nuf said on that topic....

to OP.... when you sober up do some more calculating because 7.30's are not even close!

 

you do realize your doing YOUR calculations on a computer and im doing MY calculations from REAL testing at kennedale in the 1/8th..... according to your computer tell it the car has a 1800 stall and then tell it the car has a 4000 stall there is a huge 60ft time difference and huge time difference in the 1/8 from a stock stall to a 4000 stall also tell your little computer the car has 2.73's then tell it the car has 4.10's once again there is a huge difference on 60ft time and 1/8 time and a REALLY HUGE difference when you have both a 4000 stall and 4.10 gears over stock stall and stock gears..... all your doing is putting in a number for weight and a number for hp then it spits out a number for what time it thinks it will get..... its a total guess in the dark, the computer dosent replace real testing and expierences

 

My car is defiantly not stock and the calculators are dead on for me. For my MPH anyway for the ET its getting closer. Thats why I was useing the calculators and trusting them, because I have proved them right.

My car has a **** load of stuff done to it and I can only manage a 7.9 and I have 4.10 gears and a manual. I launch at 5000rpms. So tell me how your buddies car with 300hp and just a stall and same gears as me can run 8 tenths faster than me with 360whp?

 

i assume you have never seen a dyno sheet of a car with a high stall have you??? you see on a 6 speed car your power and torque goes up diagonally higher towards higher rpm's, with a high stalled auto the torque max's around the 2500-3000rpm mark and is basically a striaght line all the way to red line, also the stall adds ALOT of torque, i believe he had something like 430ft/lbs at 2500rpm and it stayed there till redline.... thats what makes a car fast in the 1/8 NOT HORSEPOWER but TORQUE,.... torque is what takes the weight of the vehicle and gets it moving from a dead stop, horsepower is what pushes the car while it has momentum..... thats why all the big turbo cars like supras are fast on the big end and slow at the take off, sure they have the horsepower to blast through the big end of the 1/8th but,... the cars with stroker motors and big stalls are all about front tire lifting TORQUE,..... and thats how we out ran a 600rwhp 04 cobra multiple times, dont get me wrong the cobra would have got him in the 1/4mi. but the cobra just couldnt reel him in fast enough in the 1/8th,.... so yeah you can have more rwhp and get smoked by a car with less hp in the 1/8 pretty easily

 

Whatever buddy...

 

this thread is funny

 

I agree. A stall and 4.10 gears will get you into the low 7s 1/8. Just plain funny.

 

took almost 500hp to get my ta in the low 7's. mid 600 to get it into the 6's. Its a 6speed though

 

Well your car is a pig then, not all 4th gen weighed the same from the factory. My 2001 Camaro SS is a stripper with me in the car it weighed 3480 (3290 without me) on the scales. All I had was a Yank ST3500 stall converter, a set of FLP headers, lid, and a set of BFG 275/40/17 drag radials on stock wheels all the way around. Just the spare tire, rear seats, and jack removed. At MIR I was cutting 1.59 60fts, crossing the 1/8th at 7.538, and finishing the ¼ at 11.87@113mph with a car that was on the dyno at 326rwhp and 342rwtq. There were cars similar to mine that were 3 to 4 tenths quicker because they were using 4000 to 4600 rpm stalls, gearing, and taking advantage of location and good weather.

This is why your logic is flawed because you are not taking into account all the variables. Do not ever compare a manual car with a stalled car at the drag strip. It does not matter that you launch at 5000rpms, you are not getting torque multiplication like an auto, further as you are shifting gears your RPM is dropping out of the powerband, a stalled car runs at peak power all the way down the strip, my RPM never dipped below 5000rpm down the track. You are comparing two numbers that are obtained in two completely different ways.

I doubt the new Camaro will obtain 7.30’s with a stall and gears, but that remains to be seen, realisticlly 7.70's-7.80's. No one knows the actual weights on these cars or the variances that customers will observe, add in to the mix IRS and those 60fts are not as stellar as a solid rear axle car. But I can say this, there is going to be variances in weight. The 4th gens proved that with 400lb variances.

 

finally someone that knows something about cars!!! this dude is running low 7.50's in the 1/8th with just a stall and exhaust and drag radials.... and thats with only a 3500 stall, i promise you if he had gears "4.10's" he would drop his 60ft which is already a 1.59 which is awesome for an exhaust and stall only car but very possible, and gears would drop his 1/8 time by at least 2-3 tenths that would put a basically stock *he does have exhaust* but other than that it would put a otherwise stock car with just a stall and gears and drag radials at 7.30's in the 1/8th and THATS ALL IVE BEEN TALKING ABOUT THIS WHOLE TIME!!!! note: the 2010 will be a little heavier and the IRS will be different but you do have to keep in mind they will have almost 100hp over a stock ls1,.... and the auto has 1st and 2nd gear that is taller than 1st on the 6spd,.... meaning it will launch a killer 60ft time and awesome 1/8th time espically with gears and stall.....

 

I doubt 100hp difference, the 01-02 LS1 cars were severally underrated at 315hp and were much closer to 360-380hp cars. The new L99 is rated at 400hp and you will not see numbers in the Camaro going over 430hp, the Vette which has a better tune on a LS3 is just barely seeing 450hp stock. The biggest difference will not be the peak power of 70 or so hp, but the broader power curve of the larger displacement engine.

Gearing is not feasible on such a car, even on the 4th gens running a gear did not result in net gains in the ¼ or in the 1/8th for that matter. The steep 3.06 first gear in the 4L60E was perfect for the standard 3.27 rear gear. You may have gotten away with a 3.73 gear and gotten off the line if you had a good track and great tires, but 4.10’s were nothing but spin city. The new 6L80E has a first gear of 4.02, you are not going to be running gears on this car.

No one ran 4.10's on an automatic car and kept them, they did not result in gains and even by chance if you did hook, they typically broke.

 

Almost identical to my results in my bolt ons only stripper Z28 automatic, though my raceweight was a little lighter (roughly 3390 with me in it).
1.59 sixty foot, 7.51 in the 1/8th and an 11.86@113.62 in good air at Atco.
Dyno'd roughly 335rwhp/336rwtq.

 

True, the actual horsepower difference to the wheels between an automatic 4th gen V8 and the 2010 automatic V8 will likely be less than 80hp.





3.23 gear actually and they weren't standard on all automatics, they were either optional (and required the 'Z' rated tire option) on the Z28/Formula/Trans Am or standard on SS/WS6.
The new car will have 3.27s of course.

 

Im just surprised nobody has mentioned how much taller the tire is and how that plays in...

 

Good point and it was discussed briefly in this https://ls1tech.com/forums/gen-5-racing-tech/1012636-2002-auto-vs-2010-auto-questions.html thread, those tall wheels/tires will certainly (numerically) lower the final drive ratio. That of course means that the cars will respond very well to gears (3.73s/3.90s if someone ever makes them for the new car) on the stock stock tire and/or will also respond well to shorter (26") drag radials.
The problem there will be the TC and ABS.

 

The LS1 FBodies were actually around a median of 350 HP at the flywheel (when looking at what ppl dynoed. There are some freaks out there. But working with roughly 15% drivetrain loss they come to 350 HP at the flywheels regularly. 360-380 HP is overstating the case by quite a bit and only rests on the evidence of some factory freaks. Likewise the LS3 will probably be around 450 HP realistically.

And 350 is understating it, at 305rwhp on my auto bone stock with 15% it comes out to 360, and mine is far from a factory freak. Some guys were getting 315 to 320, maybe read what I said specifically 2001-2002 cars.

 

well according to BLK85 thats impossible
i bet you BLK85 is with all these nearly stock auto guys getting 7.50 in the 1/8
he's probably saying and i quote i have a ton of **** done to my 6 speed and

 

True, but then again 7.5s are not exactly considered low 7s...that's a lot more difficult to achieve.

 

No use arguing with people that are completely wrong. I doubt the guy you quoted runs 113mph with 335whp. I run 112 all the time with 360whp. The 1/4 time of 11.8 I could believe, but mph is determined by power. So this guy has less power than me but ran 1mph faster. Theres something more to this story. Just because you run a quick time once, that doesnt mean crap to me.
