So almost all my mods are on my sig...i had a fp green but it had problems and im not going to dump more money into my stuff like that again for a bit....Im running a constant 12.50 in a car thats buschur tuned and it is rite under 2800 lbs...Would an evo 9 turbo + BC 272 cams + RC 1000 cc injectors and a good tune at 25 psi get me there or beter??

 

Im also running 23.9 psi on my stock turbo tappering to 21.7 psi and havent got a 1/4 time with my new clutch and flywheel...

 

My stock weight Evo 9 (3300lbs) on E85 with GSC 1 Cams and bolt ons runs consistant 12.0's in Tucson (bad DA). I would expect you should be able to run a 11.8 with those mods...

 

I think it all comes down to your 60 foot

 

I think if you haven't purchased the BC272's yet, don't, because you can achieve WAY BETTER gains with just a few more dollars spent on a real cam. Other than that a 10.5 hotside will work perfect, I've seen pump gas Evo's around here with Comp 272's/10.5 Hotside/TBE/Emery@STM tuned trapping 120 running 11.50s. It only takes 115mph if that to dip into the 11's with the driver mod.

 

Very true. Also how fast you shift and what rpm you are shifting at.

 

my 60 ft is 1.7 and my reaction time is .463....I shift at 7400 rpms from 3rd to 4th and i shift really quick...as for the brian crower cams i have them allready...i didnt buy them, they were given to me..i knew better than to buy that type of cam but you cant beat free! lol...what this all comes down to is i want to be able to beat a stock Z06 vet....they run 11.8s all day...

 

Reaction time has nothing to do with your time. Clock starts when you start moving. 1.7 60 is ok but on avg people usually cut 1.6 60 fts. People that are really good are able to cut 1.5 or quicker. You want to shift in your powerband not at redline. If you have a dyno chart you can see what rpm you should be shifting at.

 

i agree with you about the 1.6 and 1.5 but i think that a 1.7 is the best im going to get out of my 8 turbo...as for my power band im suposed to shift at 7200 rpm

 

Not true. I was on my stock clutch and stock 8 turbo and I was cutting 1.6 60fts and when I finally dialed in the tire psi and 2 step speed I was cutting 1.5 60fts. I got about 5 1.5 60fts and then the clutch said no more. My Evo with me in it at the time weighed around 3450 also. I guess what my point is the more practice the better your times will get. Driver mod is the best mod
