Dyno Results after RENNtech Pulley/ECU...
456.28 and 505.70, dyno graph here:

RENNtech needs to reflash my ecu with a newer program, waiting to get my recalls done first....

I think it's time for a track rental.

Those are indeed strong numbers. I'm pulling 480rwhp and 549 rwtq with pulley, ecu, headers, and IC mod. I thought those were strong numbers. You throw on headers (deleting your primary cat) and an IC/mod and you'll top those numbers very easily... Congrats on a very strong E55

very nice.... do you have the dyno sheet to post? I'm starting a collection of them....
Derek, my car made 419 stock, but different dyno, it was the Viper club's dyno day.... temp at the dyno yesterday was 91 degrees, 28% humidity.... not sure if that matters.....
BTW, my car made more power/torque than quite a few Vipers there....

The most common are the SAE standards. The older J607 standard considers that the engine was run on a 60°F day with 0% humidity and a barometric pressure of 29.92 in-Hg or the newer SAE J1349 standard of 77°F (25°C) day with 0% humidity and a barometric pressure of 29.234 in-Hg (99 KPa). Also the ECE standard is the same as the SAE J1349, but does not use mechanical efficiency in the calculations. The DIN standard which corrects to 68°F (20° C) day with 0% humidity and a barometric pressure of 29.92 in-Hg (101.3 KPa) and the JIS standard corrects 77°F (25° C) day with 0% humidity and a barometric pressure of 29.234 in-Hg (99 KPa), but uses different correction curves than the others (as a substitution for using mechanical efficiency factors). Further, we have the J1995 corrects 77°F (25° C) day with 0% humidity and a barometric pressure of 29.53 in-Hg (100 KPa).

it would, I used what ever was used for my original dyno..... it's dynojet's software, and they have all of those correction factors available... I would say the latter SAE standard, since the JIS factor is within 1HP....
odd that the totally uncorrected numbers are within 2HP/TQ of the SAE numbers, and it was really hot and humid....
thanks for the notes on the factors....

Wouldn't it be nice if life were easy and there was only one standard . . .
