hey, bro yes it is untuned. The air fuel is low 11s. steve at Weistec sent me a new file which I have not put in yet. I have been driving it on the street with light driving and half gear pulls. this particular file in the car is by tony though.
I am seeing max timing at 17* .....

What correction factor was used? It's cut out of the picture
I'm a little confused. You added 2 psi without any other changes and gained 70whp?
Your baseline dyno says 577 but in your for sale thread you said "It makes 635rwhp/680rwtq on 13lbs 93 pump gas."

Also your previous conversions from BIP dyno to dynojet numbers that were criticized (several different time) don't seem to be very accurate. According to your previous post...
"Car made 546rwhp/671rwtq Dynodynamics
Car made 631rwhp/671rwtq Dynojet equivalent"
BIP dyno dynamics 546whp = 577whp dynojet. 31whp difference not 85whp
BIP dyno dynamics 671wtq = 566wtq dynojet. Dynojet actually reads 105wtrq LOWER than BIP dyno dynamics

I am a little confused as well. I calculated a 1.056 increase with the pulley size change, which should be somewhere around 610whp from 577.9. I was about to ask what else changed. I would assume cooler intake temperatures if timing or nothing else was changed. Maybe a better a/f as well if it was to rich before.

where do you get the 62.5mm supercharge pulley? and what size of the crank pulley now?
my weistec s/c is runing with a weistec 150mm crank pulley, and i am thinking to put the 180mm crank pulley on, and asking weistec if need a new tune to work with, but they didn't answer me....

Ahmad, your guess is as good as mine. Changed to a smaller blower pulley, went to a different dyno, and got the results above.
Honestly, all I am doing here is sharing the results, I could careless whether you believe it or not. Different dynos, different times of year, etc etc etc will yield different results. When I take it back to the track I should run faster trap than last time of 130mph as it looks to be making better power.
The wiggle in the beginning is converter lockup fellas for those who asked. I got the smaller pulley from weistec.

it is what it is I could ship craigs car up to my dyno and it will make the same power. I own a dyno jet not sure how many of you guys do I strap the car on give it hell smoothing five and leave it on std. It will make the same power.

Any time you play with boost I would recommend a retune. Why not just change the upper pulley? Much easier with the Weistec SC.

We are talking about in comparison to BIP dyno. You think it will make the same power on your dyno as the BIP one? You seem to be very biased but I'd like to hear what you have to say.
