I for one have never understood how a car can perform on the street and not the track.... Even when I use to not be able to launch my car because of the 10 bolt it still trapped pretty good.

Perfect example here this particular vette when it made 373rwhp went 12.50 at 115 but beat 2 heads cam fbodys that i know for a fact are great drivers from a roll....key word being "roll". This particular vette also when it trapped 115 beat another vette that runs consistent 120-121 mph and then backed it up by racing him again and running door to door all the way to 160? How does that happen? Its the street and anything can happen. And vettes are absolutely amazing from a roll. I cant even remember how many cars ive beat that ran a better et and had more mph.....in this case....he beat me and there is a good chance i will run faster at the track.

He understands that he's seen me run terrible times at the track lol and still run fine from a roll. I'll try and disprove the trap speed thing to him by letting him take my car down the drag strip and show it'll trap alot higher than what I've done just from a good launch compared to my terrible ones haha

The cars that trapped higher at the track were driven better. The vette still ran the same as usual he just couldn't get out the hole.

I'm not a big gear fan. I use it more as a tuning tool then slap gear in something and expect it to go. I have taken gear out of the 2 cars I have hotrodded and went faster.

Yep.....changed from 4.11 and the car went faster. I don't think 3.73's would hurt it any. Actually when the ls7 goes in I will probably run 3.73'sonce it is sorted out. Gear is a tuning tool. If you rely on gear to make your car quick/fast then you simply don't have enough motor......or you have a real narrow power band and tq that sucks.

You n/a ford guys are the ones relying on gear. It's really not that big a deal in my world. When I switched from 3.42 to 4.10 I only picked up .1 and 1mph . When I went from 4.10 to 3.90 I can't give a accurate time (if I were to guess -.2et & +2mph) difference because I haven't ran it on the 18's since the gear change and now there has also been other changes. But I can assure you of this, my car would've never trapped 130 with the 4.10. It was on the limiter @ 122 with the 4.10. I don't think 3.73 would hurt it. I'm actually gonna use 3.73 with the ls7.

I guess the texa speed h/c car should go back to 3.42s since it is a tuning tool and only helps weak n/a modulars :eyes: 130 lol yea ok It would probably go 10s in that light ass car with 4.10s

I don't know which car your talking about. But to go 130 on a 26" tire with 4.10 ain't gonna happen @ 6800rpm. Apparently they would've used a taller tire, which is all part of the tuning. I wasn't goin to change to a taller tire to get threw the 1/4 and then have my normal street set-up be off.

Idk about the t56 but a mach with a 26 and 4.10s is ~130 at 7k. We also know your 130 trap is skeptical. The car is the h/c record car. There is a reason all the faster h/c cars run alot of gear and it is not for street tunning purposes lol

Your not leaving any room @130 with 4.10 @ 7k unless your relying on tire growth. The calculator I used was off 5mph(5 to fast), I found out by being on the limiter before the trapps hence forcing me to do a gear change. Mustangs and Camaro's should be 1 to 1 in forth so no change.

My car goin 130 could be skeptical. Definitely controversial. But it did 129-130.xx 9 times one day and 129 on another trip. But there is no denying that it always does over 126. Could've been good air or the other small changes coming together.

The selection of the final drive gear is all dependent on the max operating rpm (not peak hp rpm). Higher reving engines regardless of hp, ALWAYS take advantage of steeper gears. Gears just multiply the torque in any gear. Its a win win situation.

I realize the rpm thing, that's why I stated rpms, also that gear mutiplies tq. But gear is not as important on ls stuff. Or any engine that makes decent tq.
No saying 1-3 is not the same ratios. t56 26in tire 7k 4th 131 by the calculator not sure how it could be 5mph off.

I know 1-3 is not the same. I was speaking 4th. All I know is the calculator said my car could go 127 with 4.10 @ 6800 and I hit the limiter @ 122 before the trapps. Seems to me the calculator is a bit off. Now I turn it 7000 with the 3.90 so it's not a problem, but it was getting close on the 130 runs.

Now here is a video of me racing a H/C/I camaro me and him were dead even when i was bolt-ons/tune. Him and the 01 cobra were literally dead even too. This is what I did too him after the cam swap with the car not letting me go into 4th.
http://www.youtube.com/watch?v=dMXHOTO_hMI

Here is me racing a 490 rwhp cobra when i was boltons/tune he traps 123. I raced him after i put my cam in and walked him hard like 4 lengths.

Now here is a video of me racing a H/C/I camaro me and him were dead even when i was bolt-ons/tune. Him and the 01 cobra were literally dead even too. This is what I did too him after the cam swap with the car not letting me go into 4th.

Every car and race is so different. I do feel like my car is strong. Plus your missing out on the bigger picture my car has big and lils and a 410 gear. From the cars you have beat up on you may be shocked if we could race.

Last time I went to the track i trapped 101 in the 1/8th and 125 in the 1/4 bogging off the line to a 1.9 60ft and still ran a 11.4 full weight . When I put my skinnies on ill probably trap 127. My buddy with a H/C/I ls1 240sx said I would be shocked too until i put 4 lengths on him.

They are. Car blows right threw the meat of the tq curve. There were guys at the track back when these cars were newer with 4.10 and they would never be more than .1 quicker and would have 1mph less than me with 3.42.

For example my car makes about 340wtq @ 2000 rpm, peak of 405 and it don't drop below 360 clean to 6800. No need for alot of gear with broad tq like that. 3.73's probally would not change performance and may help it. Could also be the reason it went quick/faster with a change to a 3.90. I could've turned the limiter up a bit as it was @ 6800(7000 now) back when I had 4.10's or put a taller tire on, but I never felt the 4.10's loaded the car very hard. They just did alot of revving.

Maybe this is why my car runs like does. I don't just throw shit at it because of what others do.

As far as not picking up much on the backhalf. I think the 1/4 mph at the track i run at is 1-2 mph low. Every car that runs there reads low. My friend with 730rwhp cts-v only traps 127-8 and like 103 in the 1/8th but runs 10.6 in the quarter just doesnt add up cause his 60ft are not just awesome. My other friend with a supercharged/nitrous c6 ran 10.2 at only 132-133.

The ONLY reason on why your car picked up is because you ran out of rpm with the 4.10's. Plain and simple. Your 1/8th time would have been faster then the back half where u ran out of rpm is where the 3.90's walked past your 4.10's (pending the same 60ft for both). Its simple math....Oh I forgot..you're from Virgina. :poke: j/k.

Take your torque numbers and assuming a 1.1 tranny ratio...

4.10
@2000... 340*4.10= 1,394ft lbs
avg of 360*4.10= 1,476ft lbs.

3.90
@2000... 340*3.90= 1,326ft lbs
avg of 360*3.90= 1,404ft lbs

So it doesn't matter if you're in 1st, 5th, or reverse... the numerically higher gear will accelerate the car faster. You gear the car based on the max rpm. If you can't make it past the traps you either lower the gear or raise the max rpm.

Your not taking into account that the taller geared car stays threw peak tq longer....thus applying more tq over a certain period. Like I said I could've raised rpm with the 4.10, but the car would've been past the best power range to keep the car accelerating hard. More gear also uses more power. You did not factor that into your math.

You do realize that your argument of staying in the powerband longer (time wise) = less acceleration force? 2.73's will keep you in your torque curve (aka rpm range) much longer than that of a 4.10. Which do you think will win in a drag race? This "blowing past" the curve is a common misconception. It may feel like that but what you don't realize is that your acceleration g's are greater with the steeper gears. If you still don't agree I can break out the math for you.

04-12-2012, 02:15 PM
Well im still not agreeing. For sure you cannot go to one extreme or the other. your not taking into acount the gear change either. You have to change to the next gear earlier with the lower gear which leaves a split second for the taller geared car to have more gear multiplication. It's not as simple as simple math. When I first changed gears in my car years ago we had a program we plugged my Dyno #'s in to chart acceleration with the gear splits. The stock gear(3.42) & the 4.10 charted to 150mph in the same time. The 4.10 of coarse took off faster but from 80 on the 3.42 started accelerating better.

Maybe for your application you didn't see desired results. But when my car was stock with nothing but original SLP mods (blackwing/cat-back) I saw a consistent .2 gain in the 1/4 with 4.10's. With my experience with the LS6 loving high-rpms I wouldn't run anything less than 3.90s with a T56.

Thank you. I did forget one small part of the equation for him...Driver error.

Hihoe- to put it to where you can understand it. Use this calculator. I think the math might be a little too indepth. But pick any referencable car from the drop down. There is a c6 so the hp and weight is probably close to yours. Do a test with 3.90's then 4.10's. Once you hit calculate it you can see the metrics for the different mph intervals (speed vs time, acceleration vs time, distance vs time). You'll see that in all the categories the 4.10's are quicker in every aspect including 80-120 that you said the 3.90's were.

So you rev your motor to 6,800rpms per you but you make your peak power low in the RPMs? :confused: And how do lower gears "use" more power?

HioSSilver
04-12-2012, 07:14 PM
I rev limit it to 7000 stoppy. The engine carries the peak power out flat. Lower gears use more power because they turn faster. That uses power and creates more heat and/or the some power gets disapated as heat. Lots of guys have lost rwhp from changing gears/rears.

Bite I could not get the website to work, maybe because I'm on google chrome. All I can tell you is the change from 4.10 to 3.90 was a noticeable seat of the pants difference that showed up greatly at the track. Like I said the program we used on the race team I worked for the 3.42 was starting to be better above 80 and was alot better by 125. I have more faith in that software that we used to gear our hewland gearboxes vs internet download.

03turbomach and I set the rear up and we both noticed the difference. It just seemed like it pulled harder everywhere. Actually loaded the motor instead of just revving. Track times confirmed it.

For a lot of people, one tenth would justify the gear change. Believe it or not, a majority of people don't race trap speeds like you do. At the track, it's who gets to the finish line first. You race trap speeds because your car "is set up for road races" or whatever you claim, so it is convenient for you to have an erection over trap speeds. You always claim what suits you (in this case gear giving you less trap speed at the track) is how it is "supposed to be". I seriously don't understand how someone like yourself can be so biased and not realize how biased you are. End of story. If you like roll races, less gear, track, more gear. Not everyone has the same taste as you...thought you would know this by now.

You've got it all wrong. And then you take what I said out of context instead of trying to understand it. Sure my car trapps good. But 11.1 is pretty quick also. As everyone knows trapp speed is a good indicator of how a car runs once it gets moving. If I can change gear and pick up mph but et stays the same, then I'm gonna change the gear. The car definently don't run like it by does because I did things like others have said or have done. Not biased at all, clear open minded thinking to get there. It would be dumb of me not to admit that it runs good(et/mph indicates that), that's not tooting my own horn. I think it could go faster, but that's not gonna happen now because the clutch is slipping and I'll just go ahead and put the 7 in sometime soon.

Look around, guys dyno less all the time at the wheels with a gear or rear change. Some guys has lost as much as 10-15 whp changing to a 9".

A 9" will lose a tad amount of power due to the pinion being well below the ring gear centerline, thus increasing friction resulting in higher gear lubrication temps. With that said, you're looking at a 3-5% hp loss - very minimal. A gear swap in a stock 10-bolt like yours would probably see no decrease in power.

04-12-2012, 10:43 PM
You do the math on 3-5% loss @ 400rwhp. Then please tell us what it is. ;)

My point is, you have a 10-BOLT. The 9" rear is a completely different animal in itself. With a 10-bolt your not going to lose much if any, a couple hp at most. And the gains you see in acceleration are well worth it.

You lose the power by going to a lower gear because the gears are spinning so fast they are acting as a prop in the oil thus they create bubbles. Atleast this is what I think...

Also by going to a Ford 9" from a GM 10 bolt you lose power because going from a 2 letter word to a 4 letter word doubles the surface area letting the power spread out further, thus lowering the peak...

"GM's design is more efficient than Ford's. A 12-bolt's pinion is 1.50 inches below the ring-gear centerline compared to Ford's 2.25 inches. For the 12-bolt, this results in a 3-1/2-percent-less horsepower drop through friction reduction and lower gear lubricant temperatures. The 12-bolt is also around 30 pounds lighter than the 9-inch."

Bite I could not get the website to work, maybe because I'm on google chrome. All I can tell you is the change from 4.10 to 3.90 was a noticeable seat of the pants difference that showed up greatly at the track. Like I said the program we used on the race team I worked for the 3.42 was starting to be better above 80 and was alot better by 125. I have more faith in that software that we used to gear our hewland gearboxes vs internet download.



Open it on IE and see what it does. So you went to the track on different days (i.e. weather conditions) and you saw a mph pick up and you think the gear swap was solely the reason? Please tell me you're joking.

This guy in this thread also had the same thinking as you. Is everyone else wrong in the thread too? Many of them have n/a motors that run 4.10's and are faster. They must be doing it all wrong.


http://ls1tech.com/forums/gears-axles/1244750-4-10s-too-short.html

I also saw another thread where you chimed in and said you did a few things after the swap to 3.90's and u picked up mph. So that wasn't mentioned in this thread either. Go onto YB and ask the very same question. You'll get the same answer as what I'm trying to explain to you.

But now that I think about it...I'm wasting my time/effort trying to educate you so keep your 3.90's. You'll never open your mind and try to understand the math behind it. I'm done.

Wait...didn't Mystic give us some insight about this? Like more gears means more power...or vice versa...He may have been onto something.

HiO your car may be a 126 car but your credibility gets lower when you say ignorant shit like you have in this thread.

Yea yea yea....blah blah blah

Bite I never got a true back to back after the 4.10 to 3.90 gear swap. The only real change was my drag wheels with dr's when I went back other than the gear. But still not a back to back. I can to you the back to back of the 3.42 to 4.10 was .1-.15 and 1mph. Same wheels /tires although a different but comparable day. Not as great a change as everyone thinks. I'm sure gear works good for your 4.6, you need to multiply all the tq you can.



As a side note. I still have all my inner bumbers, alot of fbody guys remove them, pm those guys if you have a problem with saftey. Doors bars are still there and the main chassis have never been cut on. Just bolt-on parts and a careful selection of how I do it and the parts I buy or make. I've had lots of guys pm me about what and how I've got the car that light. ...remember, if I were to wreck it there is also less weight to stop on impact or if someone were to hit me it's less weight to move. Bet you did'nt think of that angle.

Bayarea....your car would'nt run like it does w/o h/c. I don't know why anyone would blame my #'s on weight alone. If you want add 400lb back to my car in your head if it makes you feel better. We've all chose our mods here. Keep a open mind and live with it.

What does your car weigh?

Well hio like I said there is a reason why all the fast h/c cars have alot of gear for the most part. Also i think you make more power then bayss. your car would not run the way it does without the h/c and compression bump.

Weight can very a little Corey. I can get the car as light as 3000, but it's really low on gas, has my bogarts on it, no front swaybar and no dd crap in it. About +30 for the for the 18's with the bar on it. Last time at the track I had 3/4 tank and dd crap in it. So about 3050 or 80 that day and went 11.1@ 130. I weight about 165 dressed. Those are car only weights. Scales are a local quarry that measures in 20# increments.

Auto I don't think Bayss car is as strong. Didn't he get outran by a pullied cobra in a recent vid?? I can handle those pretty good so far.

If I didn't have h/c i'd still have a bolt car that runs 11.80s which is damn strong. Your car wouldn't run as strong without the ls6 and the power tools



Auto I don't think Bayss car is as strong. Didn't he get outran by a pullied cobra in a recent vid?? I can handle those pretty good so far.No sir you have not saw any recent vids of me racing. Most recent vid of me vs a cobra is me pulling a 2.9 whipple cobra with me on the motor. I have no problem with pullied cobras

His car is faster it has been 10s
True story.

Yes I handle them well. If I did a lot of weight reduction and ran in good air i'd be doing some major damage at the strip.

btw... What was your 1/8th mile on that 11.1 at 130 run?

I think my 1/8 was 7.2@98. My 1/8 has been weird this year for trapps. Anywhere from 98-104. On the 104's I did spin pretty good in 2nd.

I don't remember the vid of you and the whippled cobra.....but good kill. Whippled ones are tough.

104 seems like a very high trap but 98-101 would make more sense.

3000# is very light! That helps your car tremendously. And your trapping 130 on spray right?

Because it's true full bolt-on. It's pretty normal for them to make 400 with headers , intake and a tune. Drivetrain on a fbody is probably more efficient also. Also has almost 80k on it now......running good and free.
