auto here..... full boost by 3000 rpms. my stock tranny lasted only a week with a turbo. swapping a 4L80e isnt stock either.

 

food for thought I gained 6 tenths by going to a 4L80 with transbrake leaving just at boost. the M6 suxed for drag racing. unless you roll race.

 

lol brutal.

 

just so people know, i was talking about street cars, a stock gto auto or manual. I have never been to a track, never even seen an automatic transmission manually shifted. I thought that would **** up the trans? or is it different in race cars?

sorry for my ignorance, but i am new to this game, as is obvious in my posts.

 

A stock trans will not last with boosted ls1 cars....even with low boost.

 

Just do what I'd do and make more power. Building boost off of the line isn't as big of a problem if you can make it up on the big end.

 

What?

 

they will with blown cars..my M6 was fine at 650RWHP in my goat,but common sense and lifes lessons all say the auto will kill the 6 speed.I will however say i have cut some of the same times if not better than most of the auto gto's out there.I do however know i will be looking at a auto for my turbo build and it wont be a stock auto...
