my mods are a JDM 90 mm program ,90 maf ,single blade t.b ,filter kit and one LEAKING intercooler. it was a dynojet dyno.
my best H.P was 361.1 and torque was 450.2
let me hear some input please . does the leaking intercooler affect horsepower?
Thanks Jason

 

Looks a little low, but the ic leaking isn't helping it... I would assume about 390-410 horsepower with your mods...

Fix the i/c and your #'s should be about right.

My stock '00 dynoed 309rwhp , but the guy that did it dynoed the truck in 2nd gear and left the a/c on .The 99* air temp didn't help either...

A bit off topic: Did you notice a difference switching to the 90mm maf?

 

Justin,
i think your thinking at the crank?can anyone calculate what id have at the crank with 361 at the rear wheels?
thanks Jason
rscoleman,
going in for the new intercooler next week already ordered the parts . as far as the 90mm . i went from a old Swanson chip to a JDM with the 90mm . it really suprised me!JDM has their **** together thats for sure !

 

Retics4me-

My baseline dyno (completely stock) was 342 SAE Horsepower.

My best dyno (after mods below) was 368 SAE Horsepower.

JDM chip / filter - warm weather program
JDM Throttle body
JDM Water pump
Bassani headers / exhaust
JDM Electric fan
NGK Spark plugs

If you dyno at 361 rwhp, that translates into about 407 hp at the crank assuming a 11.2% driveshaft loss. Some trucks (with the exception of mine) are getting close to 400 rwhp with only a chip, filter, lower pulley, and minor other mods.......... - I witnessed it last weekend at a local dyno day session.

Mine dyno'd at 377 RWHP with Swanson Chip, Pro-M Mass air, and leaking IC. A small leak probably won't make much difference.

A big one will.
