Turbo compression ratio

Go with a svt head gasket. CFM has decent prices.

I can show you 1 bad engines from e85 for every one that says its running good and its only a matter of time with thos, I have tried e85 and many times and I can see the knock sensor go crazy from one tank to another that tells me all I need to know , what about the engines that dont have working knock sensors BOOM

So you think 400 rpm faster spool will be what makes you win or loose a race ? no

Then the trade off for that faster spool would be more heat in the Cyl from more compression and less boost with LESS HP from the mid range to top end where the extra 50HP from less compression and more boost from 4500 to 7500 where your at in all gears but first gear which is the only place the 400 faster spooling will help , that will help you win the race

I love you guys that think faster spooling is what its all about , Ill take slower spooling (only effects first gear when racing) over more TQ/HP through out the power band 2-6th gear

Change to a ATX and sit at the line with 15psi boost and you wont worry about spool time as much

I build 10psi on the 2-step and its a manual? 400rpm is huge on a daily driver and will make a much nicer power band.

BTW this is hilarious

This e85 and 400rpm talk makes me laugh.

Those that are argueing 400rpm's is alot either has:

1. A huge turbo and lag is killing them
2. Never drove a turbo car/zetec

This talk about e85 is just as funny.

Full spool by 3600 instead of 4000 is big. That's like having a 35r but the spool of a 30r. Which I would love
