took it to the dyno today...and got some numbers finaly for the bird...

i think it still has some more on it as its not perfect yet...but it got 310rwh and 330rw torque...ill post the graph later...

so far what do u guys think about the #s.... after looking and searching around for a while, the torque seems a little lower than most...but what do i know...

basicly car is a 04 pi motor with accufab upper/stock tb (still have to work on that), catless exhaust and a vortech 8lb....even though i didnt really check to see how much it really pushed....what do u guys think

I would think with a PI motor you'd get a little more then that...Do you have a SCT tune? But yeah those are good numbers, take that beast to the track in the spring! :)

Nice Numbers. I'd like to see the graph.


Are you forged?

i think we should take all 3 black supercharged birdys to the track one day,

Jurgens, Steves, and urs.
Sure why not . Leart ur numbers are fine say a stock pi motor will dyno around 230 and u got 80rwhp from the blower you still need to get a 75mm tbody and you have stock manifolds .

Needs some work. Here's a very old dyno sheet of mine. This is a bone stock PI engine, catted single exhaust, S trim with the largest(3.6") pulley Vortech makes. Also a V1 blower which has less step up gear than a V2.

Yours looks pretty close to right until 5000, then something goes horribly wrong.

Am I the only one who thinks those numbers are really low? With your mods, you're set up is breathing just about as well as a stock '99-up Mustang....save for a more restrictive exhaust. The guys running the MPH Mongoose kits are seeing anywhere from 350-370hp and like amounts of torque at the wheels pullied for 8psi. Now, like I said, you're exhaust is a bit of a cork and you're probably experiencing a little bit more drive train loss with the combination of the 4R70W and IRS, but you should still be seeing another 30-40hp and torque as far as I'm concerned? :shrug:


kdanners graph looks much more like what you should be seeing. :thumbsup:

Like I said I think he looks pretty good until around 5k. Then it's either tuning issues, or something is maxed out, don't know what he has for injectors, etc.

Square it away and those centris are fun on the street. Not overpowering down low so you can keep it hooked up, then they pull like gangbusters as the RPM rises.

yeah...i thought that it seemed pretty low for what i got...i got 42lb injectors, sct maf, and a 225 ho fuel pump, so i do believe im clear with those issues....i have an accufab upper intake, but still the stock tbird throttle body with stock manifolds from my npi motor, then it goes into a catless exhaust into a 2in one out magnaflow out the back....its away for the winter right now, but i want to get it running right by the summer. any advice on what i should look forward or what could be going wrong....

Sounds like probably tuning issues then, everything else sounds good.
