I went to a mustang dyno yesterday in Northern Kentucky. I was a little disappointed with the numbers for my setup. They were 277rwhp/295rwtq. I expected my hp to be up around 300. I dont have my dyno sheet with me so i cant post it up here but i will tonight. I was making max hp at 5600. That is what i didnt understand, i thought that i would be making power up to about 6500, my problem might be my tf stg. 1 cam. .499/.510. I know that i need to tighten down at least 1 rocker arm on the drivers side b/c i can hear the clatter. Any suggestions? question for anyone else with the trick flow top end, how far were you making power on your dyno?

My setup:
Trick flow TW heads ported and polished, 1.6 rr's
TF stage one cam
TF track heat upper and lower, polished
Shorty headers, o/r X, flowmaster 40s
70 mm tb, 80 mm maf, 24 lb injectors
FP set at 40 w/o vac

Dont know what else you would need to know but just post anything else

 

are these numbers pretty average, the tuner who did my car said that just about every car that comes through with my general setup makes from 260-280 so idk u guys tell me.

 

If you went to a Dyno Jet, you would see 300rwhp. Mustang Dynos read lower
but are actually more of a "real" number

Good luck getting TFS top end kit to pull past 6,000. 5,500-6,000 is about right.
Long tubes might help open up that top end too. Shorties like to choke out at high rpms.

 

Why would a dyno jet read higher than a mustang dyno, this place is called modular depot so they specialize in 4.6L mustangs. I am assuming that it was a mustang dyno.

 

Mustang Dyno puts load on the rollers from how I understand it. Dyno-jet you just spin a roller with no resistance on it. Thats the easiest way for me to describe it.

I Mustang Dyno'ed mine at 196 rwhp and 247 rwtq with bolt on mods like cai, headers, off road h and cat-back.

Dont be to discouraged by the numbers, just pick one method of dynoing and stick with it is my suggestion.

 

Dyno Jet just spins a set free weight.

Mustang Dyno puts a reverse torque load on the drum and is
more of a real life simulation of what the engine goes thru trying to push your car.

277rwhp on a TFS top end kit with your mods is really dead on with what 90% of poeple make.

Again some LT's might help with top end numbers.

Dont sweat it. Those are decent numbers

 

Your numbers are descent for your mods. A better cam would raise the power band a little though.

 

pretty average for the worst h/c/i available

would have made more with GT40 stuff

 

my dyno #'s are about the same. the mustang dyno numbers run low like you were told above. they also gave me dynojet numbers at the flywheel. i believethose figures was 378hp. if you read any of the manf. #'s are in the 350hp to 370hp range with no load at the flywheel. so your doing pretty good.

 

shouldnt his numbers be higher since his heads have been ported and polished? just my 2 cents
