no...my buddy wit an 8 (9.8 hotside) ran a 12.0 at 116 mph...with just turboback,9 bov,1000cc injectors,mbc at 29psi, and 02 housing and xs engeneering 272 cams on e85....
i ran a 12.2 at 116.8mph...same mods except minus the 02

 

1000cc injectors for anything an evo8 or evo9 turbo can put out. If you plan on doing anything bigger than an evo9 turbo, better get 1200cc or higher. Are you running straight e85? If you still plan to run pump gas, i would suggest not going bigger than 1450cc's. With ecuflash, the 1450's can still be scaled down to run ok with pump gas ie 93 octane etc.
You will also need a doulble fuel pump setup with a red turbo or higher. goodluck!

 

Wow yet again people that think you need massive injectors just to be able to run E85. 750cc injectors are good for at least 400wp so why in gods name would you need 1000cc+ sized ones for a stock evo 8/9 turbo? I have 321 Hp 347tq in my gsx and all I have is 680's

 

What injector duty cycle are you getting with the 680's? and at what boost? thanks

 

yea e85 runs 30% more fuel...with 680's on e85 and about 25 psi on the stock turbo your injectors are maxed out, so whats the point???
not even a ? on a bigger turbo

 

The program me and my cousin use don't show duty cycle, what we do is get the afr to where it should be then try to richen it from there and see if we can and if we can we know we still have some left. all last summer I was running 25 pounds of boost. all I'm saying is don't get like 1600's or some crazy thing it can really mess your idle up if your going for around 400 hp get like 880cc - 950cc.
