I thought lil miller would have just strolled away from him.
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.

Here is me racing a 01 cobra with full boltons and procharger 440rwhp.when i was boltons/tune. We were dead even.

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.

I would have probably had 6+ lenghts on him if I had my Clutch master problems fixed when I raced him.

Maybe the cobra is just a hard runner, Its the streets you never know.

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.

I thought the same. I guess the LS1 guys who put 4.10's in their cars are doing it all wrong...

I raced a ported blower 03/04 cobra that made 480 when i was just bolt ons and we were right next to eachother and i edged him up top, I raced another 96 cobra with pretty much the exact same set up as cory except he has 3.90s when I was bolt ons and walked it pretty bad. Cory is wicked when it comes to driving!! just dont ask him to tighten anything more than a hose clamp, that being the extent of his mechanical abilities hahaha.

lilmiller74

If you look at my videos I have raced several H/c f bodys when I was bolt-ons and they were good races but I pulled up top, if I race them now I would assume It would be ugly as well as the ported 03/04 cobra I race..Cory is a very good driver and he knows how to use his car.

corysmach1

I only said that cuz ur posting vids of cars that have completely diff setups than me....but they do have more power. Your car is very fast i never said that it wasnt. I honestly think from a dig on the street or even a low roll you would absolutely be shocked....butbthats where my car shines. You have a nice setup for roll racing so you get that nod on me. As for me roll racing vettes is just dumb thats there game but i do it for fun.....my car is getting lighter and ill go to the track within a month and see what happens.....and why doesnt your car pick up more on the back half? My 03 cobra army tank picked up 27 mph on the back half....it was just a pullied car.

Casey- thanks for the compliments and yes i have 0 mechanical skills lol

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 **** at it because of what others do.

I hear ya. i mean im not talking crap just seems like you would pull him more. I mean every car I raced since i got my cam put in. Especially from a dig if they don't get out on me from the hit its a slaughter.

I've seen them and your car runs awesome, and it just may be that corys car is just a really strong runner. Its just my opinion I could be totally wrong though.
I hear ya. Im not hating or trying to start anything. Just in my head from my experience with my car i thought he would pull you more.

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.

lilmiller74

So far I've only raced cory and a supercharged 05-09 roush car and the race with the roush was ugly for him.

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. 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.

AWDTBSS

he only put like 2-3cars on you with bolt ons? was something up with his car besides wat seemed like a clutch issues the last gear

cory went from heavy 18s to bigs and littles. we cleaned up his maf as well which I think was robbing him of some power.

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.
