Which means with the meth added, it is almost certainly running very, very rich.


A Mustang dyno reads lower than a Dynojet. How much lower depends on its settings. We cannot determine exactly where he is by comparison unless we know roughly what a stock EVO 8 typically generates on that particular dyno.


This is where cam gears really become worthwhile. Tighten the LSA slightly and advance the intake cam about 2 degrees, and they spool as quickly as stock.

 

Latest back to back dyno candidate was a car from an evom vendor. With CFT's new computer, software and calibration whereas it used to differ 1-2% lower than the local dynojet, now it appears to be -5% under the dynojet.

 

His car was not tuned for the meth. They just turned the boost up. I mean he could pick up quite a bit with some more timing and leaner a/f. But he would be better off with a standalone or piggyback.

True, but just to help clarify, I assume you are saying +2 from where they sit and not from 0.

Before he moves any thing though, it would be helpful to know his current settings. You don't want too great of a spread (over 6 deg ?) in either direction. For instance, if he is at -1/-4, he wouldn't want to go +1/-4, but if he is at the popular -3/-3 then -1/-3 would make sense.

According to a tech at Fidanza, a +/- split set up (plus and minus combinations) aren't used on our (import) cars, but I have forgotten the technical explanation.

This may be implied also in your suggestion, but he might want to start with just 1 deg and try that. then move on to 2, etc...

Probably a bit of overkill on my part, but you don't want things banging around in there.

 

FWIW, cam gears are not mentioned in his mod list, so my suggestions are based using stock timing as a point of reference.

 

I am not sure what he is using for management, but he added 13psi of boost with alky and he only gained about 110hp, that just does not sound right. Maybe his motor has more potential with less boost but is just being limited by the stock ecu or something if that is what he is being tuned on.

 

There is a ton of whp potential in A/F's alone. It is the customer that decides ultimately what he considers safe. It is his car. There could be another 40-50whp or so in there. He had made his decision not to push it on stock motor.

 

The Car has:

Stock Cam Gears

Stock Bottom End

Dynoed on a Mustang Dyno

AFR in the high 10's

Engine Management consists of Stock ECU with Flash...

 

Ok then definetly more potential there.

 

jus a little off topic but....what clutch are you running on that car? thanks

 

Congrats on getting the kit installed and running well. I am just wondering who you got the kit from? Was it a used kit or from one of our vendors? Curious as I don't recognize your screen name. Hopefully you will be taking it to the track soon.

 

also, you are only on stock ecu, thats good power for that..... throw in an AEM and you will see over 500whp

 

The GT35R will ultimately be my set-up one day. Congrats! Bring the car out to the Brandon meet on Wednesday's (Sonic in front of SuperWalmart off of 60). We'd love to check it out.

 

its not 100% irrelavant. its all about cylinder pressure, not HP. Just the cylinder pressure needed to make over 525whp on a 35r is about the stock motor limit as far as safety is concerned. 32psi is pretty freakin high for the stock motor, unless the timing is retarded quite a bit, near the edge of EGT temps being too high.

 

Hey man, I was down at CFT when you were there(tall skinny kid). I wish I could have stayed longer to see your runs. Damn good numbers, congrats!! And I am definitely going to get a tuned by John next time, very cool guy, knows his stuff.
