ya wow great numbers

How much boost?
that was pure 93??

Amazing numbers!! Ted was right when he told me that an unmolested stage 3 could make crazy numbers. That 425trq with the s3 spool must be wild on the street.

Nice job guys

26 psi as I remember, a few gallons of 104 mixed with a tank of 93 but we feel that the Meth alone will be enough with 93 on this tune, because it is still conservative.

what was the timing??

It varies with RPM and boost between 28-21

If anything I have been accused of having a low reading dyno which is not true, but everyone is comparing to dynojets which are all over the place, there are several around me and most read pretty close but there is one that reads real high.

I believe its accurate. You seem like a stand up guy from your few posts. I wouldnt have an doubts at all except that the OP stated it made almost the same numbers on straight PUMP GAS, no meth.

With meth, things change, and 390 is doable. apparently, 390 is doable with OUT meth or race gas...

Props on the tune. and as Ive said in the past, if I were closer to you, you would have tuned my car.

very nice numbers guys , SCT is very nice to have . glad to see those numbers with using the software .

foxracing12002 · 06-13-2008, 08:20 PM

very nice. can't wait to get my maps in line. dbb 50 w/meth &all bolt-ons w/ 75%meth 25% water with 39* (yes 39 no typo) and 9. afr. so yeah, its time. congrats man. beautiful.

Thanks guys, Yes we are Excited with the software and the results we are able to obtain.

Ted.

SRT-What? · 06-14-2008, 02:56 PM

Is it too much to ask you how you tuned the fuel ?

Did you use the 'power enrichment above stoich FA ratio' table, the 'Volume efficiency' table, or a mix of both ?

I'm confuse about the VE table. Since the car is definitly not stock (ported intake, open exhaust, etc) I'm pretty sure the car has a better 'volumetric efficiency'.

Can you point me the right direction without reveilling to much detail (please !!)

Both.

VE table is the percentage of HP the engine can produce at that given RPM and Load.

Have you modified the pressure ratio scalar for the VE Table at all? I've been trying to figure out the whole pressure ratio thing. I've managed to get my AFRs where I want them without touching the pressure ratio, but I keep getting this feeling that I should be modifying it a little. On the JTEC vehicles, fuel is MAP in Torr vs RPM, which is really easy to work with.

Negative.
