Here is a data log of the car as well.

ART_Auto · 06-05-2014, 05:07 PM

No its on a chassis rolling road. I have no idea what the correction factor is but thats definitely the power assumed at the flywheel. I double and triple checked.

JWillis72 · 06-05-2014, 05:08 PM

Do you know the WHP?

No idea. I have emailed him to ask but won't get a reply until tomorrow as its 23:12 here just now.

ART_Auto · 06-05-2014, 05:36 PM

Has anyone got any feedback on the log?

I know its rich but Stillen also commented on the timing.

JWillis72 · 06-05-2014, 05:53 PM

It's not on the stillen tune is it?

gussyturbo z · 06-05-2014, 06:14 PM

I have the same kit with 3" cat back and tp. I also have the 9lb pulley and mine only makes 7psi. I think that's just what this pulley makes! The only way I think to make more boost is to change the pulley on the blower.

You might wanna check for issues I saw 9 psi on the stock pulley
You have TPs also. 3 inch cb? Losing back presumer to spool the SC ?

Custom tune. It started on the Stillen International Base tune which is good enough to start and move around but useless other than that.

Good I'm happy with my Stillen product but the caned tune sucked on my car.

I'm confused. Are you concerned that the S/C isn't creating the advertised boost or that it's not generating the advertised power or is it suddenly making less power and or boost than previously measured?

Boost values are all based on the capacity of the blower. the size of the pulley, and the engine (including intake, exhaust, IC plumbing, and valve timing) -- if you have something set up differently than Stillen had when they took those measures, you will get different results.

As to power, unless you are finding evidence of a loss as compared to an earlier run on the same dyno, I would guess that tuning bugbears aside, your car is putting down power and torque figures in line with expectations.

ANMVQ · 06-06-2014, 08:44 AM

again and sorry of I missed it but is this WHP or engine power?
"The car produced 475hp at the flywheel and 340 ftlb torque."
The TP's will cause you to have lower boost as said before but the WHP numbers shouldn't be down? You should be making the same power just at lower PSI,
Only thing I can comment it why TP's? I stayed with the stock cats and made over 450WHP( 457) but I changed some things and one of them was not the pulley. I would toss the stock cats back on , unless you want to keep the boost down under 10 since it seems a some of us had issue with engine failures with PSI over that. I did :/

And Why did you move the charge pipe? I didn't have any idle or off throttle issues and had an upgraded BPV. I did how ever have UPREV MAF's tho.

ART_Auto · 06-07-2014, 05:20 AM

It was where the air filters were sitting that we had to move. The MAF voltages were unbalanced when you put the big fan on it like you were driving.

The only cats I have are Berk Sports cats. If I put them on I am assuming I am going to have to tweak the map?

Alternatively, would putting restrictor rings in the exhaust help lift the pressure?
