Since C16 is now $90 a can where I live and no corn juice in sight, I have decided to perfect my 93 Oct. tune. The results at 33 psi trailing to 30-31 on a cool night.



100% 93 Oct
Built Turbotrix 2.0 with BR head
S2 cams
PPI Ex Manifold
PPI ported FP Black
Ported Intake with 65mm TB
BR 4.5" Race IC
Stock Ecu/Maf


This is no fluke one shot dyno #. I have been between 520 and 540 depending on the outside temp and knock count. The tune has never exceeded 3 counts of knock in the 2 weeks Ive been fine tuning it. All I need now is some corn juice to pop up in CT

 

That's great! ...and still running the MAF.

 

Wow!

 

your AFR on spool up is wicked rich, you can pickup a lot of spool response with it being leaner

 

jealous, 100% jealous max!

ccdsm track rental?!

 

congrats. very nice results!

 

What is 1.09 correction factor from a dynojet equal too on a dyno dynamics?

 

Dude, do you even drive your car? How the hell do you keep your engine bay so clean? Has it been repainted or anything? Especially considering Northeast winters. Is the car daily driven? How many miles are on it?

Good results nonetheless.

Thanks guys

I am well aware of that sir, but it aint off much. I was getting some weird knock at tip in when it was leaner. Or if you are referring to that big dip then that occurs for like 500 RPM when the turbo rushes into boost and the fuel pressure shoots way up and then it corrects itself.
I should be there Pete!
Not really sure, but most DD dynos around here are set up to read like a Dynojet.
I do drive it, like 1/4 mile at a time Its a clean 04 RS with 13K..garaged and minty fresh

 

nice power congrats and that engine is super clean keep it up

 

the one that i no of reads like a uncorrected dynojet.

 

Great job man.. Are you talkin about e-town cause i'll be there. Actually we should get some local evo's to cruise down there..

 

Hey Walt. Its actually a track rental that CCDSM is putting on at Lebanon Vally Dragway. I am going to the E-town event as well but prolly not to race..

 

I have a 9 on my car hope it makes power like yours

 

The transition to boost is often the most difficult to dial in. You either back out timing to reduce knock or richen up to reduce knock. I would typically ramp out timing hard from cruise to 0psi running AFR's in the 13:1 range. To know what is best you may want to run lower timing when tipping into boost and then lean out AFR to see how it affects spool, hp, and torque.

Either way your chart looks impressive.
