dyno numbers for a semi stocker.

[EXTRPR50]

I was curious to see what I was making with 4.10's, transgo kit, cai, pulleys and synthetic oil. The engine has about 190,000 on it.

hp-204.10
tq-269.71

This was using a 248 Dyno. that he said he tested at mph.

hp-163.89

This was found by testing the pull through rpm.

I dont know the exact difference but my luck says the lower number is more accurate. No changes were done to the car in between. I still have stock timing, and the dyno operator said it would not make much of a difference to advance it. So, do you add 20% for aode power loss for actual engine output?
Thanx

im guessing the second one is most accurate. through an aode and 190,000 miles 163k seems a little low but more accurate than the 204hp. since your only power mods is pulleys really. i would take it to a dynojet so you can get numbers that compare with everyone else's

Your numbers are decent for having almost 200k. New 95-95 GTs with a T-5 put down around 190rwhp. I think the autos were around 175 if I remember right.
