ESS 625@ 7.5psi

m33 · 04-03-2011, 10:54 AM

After our results the other day, AJ@ESS sent me another ECU tune to test, told me to put on the 7.5 PSI pulley, and head back to the dyno. *So we headed back to ICS and they opened their shop and once again donated their time to the project so we could Dyno on a Saturday afternoon.

AJ's new ECU tune ran amazing. *On the 6.5 PSI runs, we ran a 94mm pulley, and now we switched to a 92mm pulley and flashed in the new ECU file. *All I can say is...WOW! *The HP/TQ curve is so much smoother than before. *AJ told me that he modified it to make it much smoother. *You can see the difference from our last runs a few days ago.

The boost gauge at ICS is still broken, so once again we had to rely on the boost gauge in the car dash from P3Cars. *It's less accurate, but we did the best we could to decipher the numbers from the video and map them on a boost chart. *We used the trendline method to calculate boost, and it calculated an average of 6.4 PSI. *That's a lower average than our runs a few days ago. *If you look at the video frame-by-frame, you can see the boost doesn't ever get above 6.5 PSI until the very last boost spike at the end. *Even though it had a lower average boost, I just didn't feel right calling it 6.4 PSI after we had changed pulleys. *So for now, I'm calling it 7.0 PSI until we can get te boost gauge on the dyno fixed and head back for some more accurate readings.

The car drives amazing. *The power is so smooth and linear. *This car is no joke, and the 594whp on 7.0 PSI is no joke either. *Like usual, all of the dyno files and boost spreadsheet are available for download from the Dyno Database (see below). *I've got videos of the dyno runs, but I shot them on my cell phone and they ended up sideways. *I should have those fixed later today and I'll post them once they are fixed.

600whp is making a lot of power! wow

UNNATRAL · 04-03-2011, 04:21 PM

m33, if they can pull the same sort of power of a 7.5 pulley on a 6.5 pulley, does this mean that those of us with the 7.5 pulley can get a retune with more power? it would only make sense. Boys @ ESS please chime in

m33 · 04-03-2011, 04:43 PM

FYI
I'm currently just testing and can't answer your questions . I believe if you call ESS/Roman or Email ESS directly they can answer these questions.

The software that i'm running/testing might be used in a New Kit at a later date....

Brosef · 04-04-2011, 09:12 AM

wow, those are ridiculous numbers. well done.

duk · 04-04-2011, 10:52 AM

it's really 7psi then?

To be completely honest with you I'm not sure how accurate the gauge is but if it's off can't be off more by 0.5psi .
I calibrated it when when intalling the 7.5 psi pulley .
