COBALT SS/SC FOR 12s?
That could be but I'm sure they still would have snapped cuz I've had bad wheel hop in the past befor the new trans mounts. Im not sayin I'm the best or even good. I'm a machinist and I deal with custom drive shafts and axles for a living. But I'm alway open to listen and learn.

My chain tensioner is new, I hope it is just the lash adjusters. If I don't make 330whp with a TVS and a ported head with an LS4 TB... then the tuner must be junk. I know a guy that made 330whp with a 2.9 on a tvs and ls4 tb without a ported head.
its either your lash adjusters or lack of oil pressure letting them be noisey

ehh if he dropped pulley sizes and he has meth and good supporting mods if he got a good tune he could see 300 if not maybe 305... im not saying its a definate or easy to do but with a ported head and a ported blower on a smaller then 2.8 pulley he could see it.
A great tune and real cams, not some of that off the shelf garbage. Meth may be needed though. It should not require e85 to hit 300 wheel with the mp62.
What's all this noise about
as for the LS4...

The responsiveness of the LS4 can be tuned out a couple different ways. If on gas still, sub 3000 rpm just blend the gm stg2 maf and VE table, otherwise [sens.114]+[sens.116]/2 a.k.a. ltft+stft divided by 2 and multiply by percentage half or % until your trims reads 0/1...
4500 for the scaler works fantastic FYI

Cams, head work, bolt ons, and revs would sail a m62 well past 300whp. You wouldn't even need to try with the tune... could probably be attainable on 17-20* of spark by peak & 11.5 afr
there is nothing gay about weight reduction. the cheapest and most effective quarter mile time reducing mod you can ever do to your car and the only mod that benefits every single aspect of the cars performance and durability. Literally everything improves when your weight drops.
