how much hp am i lookin to gain on my evo 8 with a 10.5 hotside upgrade?

My mods are:
272 cams
full 3in exhaust
halman mbc
kn drop in
255 fuel pump
ams lower icp
flash

 

what's your car dynoing now? I would say maybe 15 whp give or take.....on the top end. With your mods including the 10.5 hotside, my friend is putting down 315 whp on a Mustang dyno @ 22psi.

 

On the same tune..maybe 5hp tops.
Tune the car and get about 10-15 depending on the EGT

 

I have heard that the 10.5 hotside is good for 10whp. Hit me up when you are getting ready to do all this work, I will give you a hand.

 

10-20whp if you re-optimize boost and retune.

 

thanks guys and thanks scott i plan on takin my car with all the stuff on it to dyna4formance for a new flash sometime in febuary

 

That is a great mod for the evo! You should definately look into having it ported and coated too while you are at it! Let me know as I can take care of you at http://www.paradigmperformance.net/

 

def get it ported for max flow

 

Hah, manOfFaith, if you're going to advertise without paying, you should probably be less blatant, hah!

 

I have a full 05 turbo for sale...

 

Yeah, I am working with the moderators right now and should have vendor status soon so I thought they would give me some slack.

Sorry if I have offended anyone, I will stick to pm's until I have vendor status!

 

Not offended - hope you get vendor status soon.

 

For me the 10.5 HS mod provided more gains than any other mod except W/M, and at $200 the best I ever spent (except for one other which was free)!

This was without tuning and porting too.

You will like it for sure, just have giant vise grips handy and tighten the WGA preload about 1-2 turns from neutral
