Hello, I'm an evo newbie and had a few quick questions!
I'm a fully bolted evo 9 stock turbo
Current mods
255lph walbro fp
Ams turbo back 3 inch
Tial recir bov
Ams upper/lower kc
Ets ic
Stm intake
Hallman pro MBC
I'm currently at 350awhp and 285tq 93 octane according to a virtual dyno.
I recently purchased 1100cc injectors with a proper tune on e85 how much powe gain can I expect?

First things first your torque is really low. Secondly, ditch the MBC and get a 3 port. On E85 you'll be able to hit around 380-400 with a tuner who knows what they're doing.

From what I've seen, you should be around 375-380 before the turbo is maxed. Cams would get you 400.

I'm curious as to why your torque is so low though.

I'm on a safe tune, and it worked out best in the actual driving experience. I do plan on increasing it with the e85 tune!

Harsh476

I see okay thank you, and I'll look into it!

Cams would get it over 400. Aaron (JohnBradley) did 420whp on a IX with a stock turbo, E85, and cams

OP I sent you a pm. And I would just keep your torque below 380wtq of you have the 6 speed tranny

Well, there is safe, then there is "why ?" 😀
I made 300+wtq on 91, safe tune.

True. I should have added that I request my tunes be on the safer side. I wouldn't feel comfortable pushing a stock turbo over 400. For me, the risk isn't worth the reward.
But that's why I have a disclaimer in my Sig LOL.
I also tend to beat on my car harder than most people, so I need a decent safety margin.

I'm thinking those injectors are max for 93 but I'd go next size up for e85

1100cc will do around 450whp on E85

I dunno, man. Had 1100s that were way up in duty cycle @ 400. I'd be kinda nervous.

Interesting. I'm at 450whp and at 90% IDC. Bad pump maybe?

the fuel pump was getting maxed out right around 475-480 or so, i think. i'm really impressed with the Walbro 255s; they seem to pump more than they should LOL. on the 1100s/e85 i was in the 90%s on duty (right around 400ish), but i try to keep it at 80% or less. maybe that's why.

maybe i'm remembering wrong. it's been a couple years.

**edit: using my math:

450whp x 2 = 900cc (pump gas) + 30% for e85 = 1170cc, so it makes sense 1100s would work.

I was planning on running 1100cc injectors on my current X build but after the math they won't be enough. Gonna run ID1300's to be safe
