Went to DYNO

[JashGTP]

Hey everyone,

Just had a great and informative trip to the dyno.

Oh car is a Grand Prix GTP, not too many mods. Just a 3.6" supercharger pulley, headers, borla catback and a little pcm tweaks with PT.


I made decent power for how pig rich i am running. Also, dyno operator had my car at i think at least way too high a speed, but i will be going back to check that out and im going to lean my car out a bit.

Here i the chart of the three pulls

Max Power: 223whp
Max Torque: 256whp

Anyone have any dyno experience want to chime in?

Also, did these on 18" wheels does that matter?

Good numbers for the mods you have. Assuming you have a 98 GP as listed in your profile you can probably drop to a 3.4 and add some timing to bring those numbers quite a bit (scanning as you go of course )

was the speed the dyno done too fast?
