Is ''10.6:1'' comp to high for boost? This is for a type R motor.

You should be safe with 7-8 PSI

 

lol ^

 

Just giving my opinion. Im sorry but I forgot you know every thing

 

once again PSI really doesnt matter, its all in the tune. A local shop around here just finished an 11 to 1 compression B16 it went up to 16 pounds and made 378whp. They used Hondata S300 for the EMS

Sorry to thread jack, but do you have a dyno sheet and setup specs of this? I'm curious to see the midrange.

Me too......

 

naw, i was just at the shop and they were telling me bout it. i know they have building the car for well over a year now. i was shocked as hell myself. i will be up there sometime this week i am sure and ill ask if he has one there.

 

it's "10.6:1".. it's a ratio.

You'll just have to keep a good eye on things with that kind of compression. There's countless threads if you search.

Yes I run 93 octane and have a 3 bar map

I was tuned by Jeff Evans both times, he said if I wanted to do a race gas tune we could have easily made 400+ @ ~16psi.

 

jeff evans ive head alot about him and his tunning abilties on stock motors!! heard of a couple 450whp+ stock GSR's!!

450whp 325ft/lbs on a stock motor, only internal upgrade is the ARP head studs.

Its all in the tune

 

thats joels car!!! [freak] i envy that thing!!

 

Jordan,

You'll be absolutely fine with the stock ITR compression. I would stay under 350whp on pump gas to be safe, anything higher look into running an auxilary race gas map. High compression isn't neccesarily a bad thing for a turbo motor, TonyTheTiger used to run one wicked setup wtih 11.5:1 if my memory serves. The negativite aspect comes in to play on the tuning end of things, as the possibility of bad gas or too much timing will quickly result in detonation, same as with low compression, there's just less headroom.

In regards to my previous setup, it's still runing strong in a friend's hatch N/A, I believe there are some future plans.

It still pulls 220 Compression across the board.

The motor has been through quite a bit: 35,000 stock miles, ~30,000 turbo miles, 200+ passes at the track, never had one issue. Just goes to show tuning is everything

Thank Joel, I was just doing some research to make sure I was ok without tearing into the motor. Can't wait to install it..
