I finally got around to installing my RC 650cc injectors, and did an EU retune with 93 octane fuel , and HKS 3 inch mufflers installed. This power is running through the stock 2.25inch-2.5inch Greddy stock downpipes, and a 3 inch true dual exhuast. So this is officially my "low boost" setting on pump gas. Higher boost coming soon......need to sort through a few things, namely, a new fuel pump system, and figuring out this head gasket/head lift issue that pops up at higher boost levels. The engine runs great with these settings looks like it was pushing to 600whp if we took it to 7100rpm.

589rwhp on "low boost"

Those are some pretty sweet numbers man. Are you gonna upgrade the downpipes to some bigger one's? Also, whats you're compression ratio, 8.6:1?

Keep us posted on your "high boost"

 

not bad! this looks very promising with a 3" exhaust! great numbers.. i love the torque too!

 

Nice tune. Do yo ustill have the stock rev limiter? it looks like the 29 hp jump at the end along with the AF jump are from hitting the rev limiter. Not that I am complaining I wish I had 560 myself

 

Congrats on those numbers....and through 2.5 inch pipes!

 

Nice job sharif keep us updated on that high boost dyno run

 

The rev limit is set to 7100rpm, but on this run, we tried to stop a tad early. I have no problem hitting the rev limiter...just feels funny at this much power, so we try to avoid it.
Gus, the jump at the end is not related to AF. We've tuned it at 10.5:1 and 11.5:1 and see nearly no change in power. The jump at the end is a little bit of boost creep, as I am still using the old Profec e-01, which sucks at high boost, coupled with some additional timing advance.

From my experience, the largest gains in power and trq come from timing adjustment, and only a little bit from AF...within reason for course. Power drops off badly beyond 10.3:1 or richer...but you dont pick up much by retuning to 11.0:1

 

NICE when you going to get some VIDS of that???????

 

I am planning to upgrade to 3inch downpipes shortly, which will undoubtedly yield another 30whp or so at this boost level.

I owe people a few videos...I promise I will bring the video cam to the next dyno session.

 

Nice, now time to get rid of those Fisher-Price-my-first-downpipes hah.

Great numbers.

 

Nice numbers brotha.....I need to get some 3inch downpipes and an 3inch exhaust........see how much power that adds...=)

 

Mam OMG low boost, how much HP are you yo planning? But that some good stuff. I can't wait to meet everyone up there. T-Netics kit should be installed by the first of the year and then here I come.

 

Sharif,

AWESOME numbers man... Congrats. You are da'man in getting the mostus from your motor safely.



I hope to follow in your footsteps shortly. (huge learning curve though )

very impressive sharif...now go get some kills so we can swap stories

 

Very Nice Sharif

 

Nice numbers! Were you running 101 on the high setting? I am upgrading my exhaust to a full 3" turbo back (not downpipe back).

 

Dam Shariff.....

Just When I Think The End Has Been Reached....you Take It To Another Level....

I Think You Are A Pioneer....

 

INSANE

 

jeezaluu.....nice work sharif.

 

I was running 93 on this run. The 622whp run last month was on 100 octane at 16.5psi.

I dont feel comforting really pushing more boost, until we do a little more research on the head gasket seating issue.
