ls turbo 1/4 mile
 

Ok first time at the track I have a 06 ls turbo cobalt I made 291 whp @ 10 psi I have pretty stock driveline, besides, I have zzp axles, zzp solid top engine mount, and poly inserts in my trans mounts. I ran a 14.26 at 105 but my 60 ft was 2.55 that was my first and fastest run I wanted into the 13's but Idk if my current setup would do that thinking about doing Fe5 lower control arms and maybe traction bars just for the track. I just bought some new bf goodrich kdw's before my runs got pretty bad wheel hop but manage able didn't go all out on my launch either. Just lookin for input

Thats still a good run for your first time man.

Look into rotated mounts from Powell, only things that will fully cure wheel hop for the F23

I was happy i wanted to do better tho lol but ya already called powell and ordered the front one but thanks a lot man I need time on the track lol

did you drop your tire pressure at all?

Get 60' down smooth for sure. Should be able to do 2.1-2.2 on street tires after a few tries. You will be in the 13's easy then. I ran 225 fronts and an ingals td tightened up for my only track day with mine, 2.1-2.2 60 and no wheel hoppin.

Real tires and you have mid 13's or better in it with practice.

I'm currently running 225 45 17 bf goodrich kdw Right I want slicks I don wanna destroy my open dif tho lol I need a LSD I feel if I get slicks lol I had stock tire pressure didn't touch it next time ill lower front tire pressure and get footballs lol and what is the prefered size for rims and slicks like tire and rim dementions any input would help man

Holy god I'm scared to see my dyno :(. My M62 setup I ran 13.4 @ 107mph with a 2.1 60' and 2.2 60'. You should def see high to mid 13's though with that trap

What u mean holy god?? And is that trap good??

Holy god as Im scared to see my dyno numbers..your at 291whp and my ET and trap are faster.I hope it's all driver mod cause i'm scared for my motor lmao.But i', goin for 12's.

fe5 wont give u a hand. just buy polyerathan bushing from 04 cavalier.


at 290whp you should run slick.

107 isn't a 300whp trap.

Never said it was lol

Ya well I have bin babying it through first it originaly. Went to 6500 at redline after my tune redline was set at 7000 for some reason I can't shift into second at higher than 6500 unless my transmission is cold cuz when I get it perfect I build like 6 psi in first and il get it right into second ill just light em up till I catch grip and pulls u anyone els have this issue!!???

Well i talked to a few ppl and they said my setup was one of the most power they have seen stock block and with a m62 I don think u are that close to my numbers how much boost u running I have a 50 mm t3/t4 turbo that's why i made so much hps that turbo flows a lot of air

Do you have a Turbo Tech Racing Aluimnum Intake Manifold yet?

Yep :D

Full bolt ons 13psi 2.9 pulley,ported head E85 on 22* of timing. :)

Id personaly say your around 250 whp range Ur a lot better off the line with that m62 my turbo is too big doesn't fully spool till around 4800 unless I break boost or launch the shit out of it!!

Haha I'd say im WAY more than 250.Especially with how much timing i'm running with E85.We will see shortly.

Cool then u can tell me what it really makes superchargers don flow that much cfm sorry to say and a stock m62 especialy deosnt maybe 260 but I doubt it post Ur numbers when u get em

indeed.haha oh just a fyi,there's a LSJ here same mods as me on E85 that 300whp.just sayin.I have more displacement and more compression which would make more power than the lsj.Im not basing my hp on his car.honestly if I hit 250 wheel I would be happy.But with some of the cars I keep with/pull,everyone here is thinking closer to 300 which I hope not since i'm on stock internals.We'll see though.

Ok I know what your saying I have same motor 10.1.1 comp. Is higher than stock lsj of coarse bit my friend here in abq nm is 16 psi tvs super charged e85 tuned and I walk him bad and he only made 255whp sorry need a graph to prove me wrong

TVS @ 255?!?!?! something wrong his car dude.M62 guys make that all day long without an aggresive tune

this!!!! it was the best mod i ever did!!! bye bye wheel hop


and about the dyno numbers, dont guide yourself from that, dyno varies from one to another.
remember also elevation. (did not read if are in the same area).
