Rpi m5- stage 1 dyno

[MPower82]

Dyno'd my car at RPI on their dyno dynamics this past week with new mods and got 415 RWHP.

Mods include RPI scoops/ RPI block off plates/ BMC air filters/ RPI pulley/ GT section 1/ GT section 2/ GT section 3. This is before the RPI ecu flash, which should add another 15RWHP.


here is a link to a video of the exhaust sound

I had 433 rwhp with BMC filters and RPI scoops stock exhaust. that was 520hp at the crank. You must have more than 415 with all those mods.

RPI's Dyno is ultra conservative...

The dyno used at RPI is a dyno dynamic and ultra conservative. Eloys methods are crazy, and he dynoes the car with the hood closed. The correction factor is about 10%-15%. So technically, my car would have dynoed about 460 on the dynojet at VF.


But bottom line, whatever you dyno at RPI, it is guaranteed that you will have huge numbers on any other dyno. i.e. Mustang, dynojet etc.....

if you dynoed 433 at Dynojet, then you would dyno about 390 at RPI.
