Wow, all I can say is dynoing your car is loud. Souded like a friggin' jet engine at 130mph.

Mustang Dynomometer

261.7 HP @ 6,250 rpm
254.4 HP @ 4,750 rpm

Stock STi's typically 220hp on a Mustang from what I've read.

K&N Typhoon Short Ram
Perrin Turbo Inlet Hose
TXS RFL-Ti TBE (w/cat)
Perrin Pulley

Ambient temps about 70F, Elevation 750ft ASL

Nice numbers, just shows you what a TBE can do...

Eurostyles East....very nice guys. I sold their dyno to them.

I've been meaning to make the 1 1/2 hour jaunt out to Pittsburgh to run my car on their dyno to see the #'s. I went to Payn Technologies and got basically the same number's you did. But I have CP Pistons, Turboback, FMIC and UTEC running about 16.5psi. For some reason, Payn's dyno read very, very low. But he said I had one of the highest HP car's with these mods that he has seen on his dyno.

Do you happen to know what weight and HP@50mph they put in for your car?

Tim,

it says 3625 for weight? and 15.70 hp@50mph?

What the hell does that mean?

I know my weight with a driver is 3410 so I don't know how they figured it out and how it affects the dyno.

I didn't know you sold dyno's, that's pretty sweet!! :eek:

Justin

Wow did you dyno in 5th?

Yep. Why? It's the closest to 1:1 ratio (actual 0.970).

Cool, didnt think sti's dyno'ed in fith.

The weight is obvious. If you know your weight, you want to put it in. The HP@50 is basically the aerodynamic coefficient of the car.....it's the amount of HP it takes to push the car down the road at a constant 50mph on a smooth, flat road with no wind.

We have a patented program called road load simulation and using these 2 numbers, we provide this simulation. So basically, the amount of load on the vehicle will be the exact same as if you were on the street. It's the closest thing you'll get to a road tune.

So next time I want to tell them the actual weight of the car plus the dyno testers weight. So, is the fact they were ~200lbs too heavy of any significance? Also does the HP@50 sound right to you?

It's not going to affect the numbers very much. It's basically like you were doing a WOT pull in 5th gear with 200lbs of stuff in the trunk. The car is still putting out the same amount of HP, it's just pushing more weight.

I think the HP@50 is also a little high. When we dyno'd my car, I had 3400lbs and 13HP@50 for my numbers. Most cars are going to be in the 11 to 16 HP@50 and most trucks will be in the 18 to 25 HP@50 range due to aerodynamics of the vehicle.

I also did my dyno pulls in 5th gear too. Doing pulls in 5th is no problem unless you have boost creep issues.

p.s. sweet I'm a scooby specialist FINALLY....which I should have been months ago after my motor rebuild. But I don't post usless banter...

I'll go with your suggestions. I think our cars are pretty close in weight and aero-dynamics should be on. I will ask them to adjust those numbers next time I dyno.

Planning on any steel cities events this year there "Specialist"? :lol:

Here's my autox schedule....as you can see, it's a little busy. I won't be going to the CenDiv events except the championship, no OVR events and probably no NWOR events. So there are a couple weekends open that I might come out.

Cool man. Hope to see you at one.

Justin (fellow small tire guy)

Very nice. Also very nice to see an awd dyno in Pitts!
