1/4 Mile Times? New Build

hey

forged 355 lt1, complete le3 package, as&m long tubes n y-pipe, wb255, dyno tune, flowmaster cat back, 3:73 rears with full spool, th350 full race trans, 3800 cone convertor, and probably like 12.1comp.


keep in mind that my car will be running full weight, full interior with leather.
i have weld pro stars with skinnys and slicks.

im trying to figure out how this should run in the quarter and what kinda street abilty it will have. i will most likley drive it every sunny day

Re: 1/4 Mile Times? New Build

im not trying to spend all the money if i dont have too, if it`s not gonna make that big of a difference.

i am hoping to be able to get the car into the very low 10`s
is it possible with this setup?

you will probably need at least a 150 shot and a bad *** 60' to get a low 10. i think you will do 11.6o-11.90 in good conditions na

If you added a blower with 12:1 cr. you wouldn't be able to drive it for even one day on the street. You need to drop the cr to 8.5-9:1 for it to survive.

how so? my friend has a 13:1comp 355 thats basically what i described above and sprays 250shot through it and it holds that, i know that your suppost to lower the comp. when going forced induction but i think that if i stayed with 10#or less i should be ok.

what about 6 pounds? another member above mentioned spraying it with a 150shot, if the car would hold a 150shot it would have to be able to take some boost aswell

Re: 1/4 Mile Times? New Build

high compression is just now being shown to work good w/ nitrous. Any other forced induction with high compression and your motor will basically melt. The only reason they can do it w/ nitrous is with a LOT of tuning and a LOT of trial and error... I wouldnt ever put any other forced induction (even nitrous for me) on a high compression motor
