So here it is: dyno of my FP Green with Jun manifold, along with installation of DW 800cc, Walbro 255 and Perrin 3-port.

You may be disappointed at the numbers, as our local Mustang dyno reads rather low compared to others, with around 50% drivetrain loss on AWD vehicles. My baseline of 200whp was stock tune/turbo with Gruppe M intake and ARC intercooler, while a bone stock MR register around 185whp-190whp.

As reference a stock 997 Porsche Turbo makes 315whp and a stock C63 AMG makes 308whp on this same dyno. So you get the idea.

My car is tuned at 25psi for conservative purpose, we did boosted up to 27psi just to see what it would be like, as expected Green seems to respond really well with high boost. I would imagine meth/race gas would really maximize the benefit of this turbo.

The following is a comparison of Green at 27psi, Green at 25psi vs stock turbo tuned at 26.5 psi

Baseline: Stock turbo at 26.5psi: 268whp/261wtq
Solid line: Green at 25psi: 296whp/263wtq (50whp gain @ 7200rpm)
Dotted line: Green at 27psi: 322whp/265wtq (60whp gain @7200rpm)



The following is a comparison of Green at 27psi, Green at 25psi vs bone stock with only Gruppe M intake and ARC intercooler:

Baseline: Stock tune with Gruppe M intake and ARC IC: 200whp/213wtq
Solid line: Green at 25psi: 296whp/263wtq
Dotted line: Green at 27psi: 322whp/265wtq



Below is the boost and a/f graph of Green at 25psi vs stock turbo tuned at 26.5psi. I am now running less peak boost but holding much better boost than stock setup.



With a dyno correction factor of roughly 53% on this dyno, my horsepower at crank is approximately 450hp at 25psi, and close to 500hp at 27psi. The newly founded power makes a huge difference in the top end, the car pulls a lot harder towards the redline and with the quick shift of SST, the first 3 gears goes by very quickly! and 4th gear scared the heck out of me...haha. Even at partial throttle, the Green is very responsive and lively. It may spool up a little bit slower than a fully tuned stock turbo setup, but the benefits of better throttle response and the top end gains outweigh the losses.

 

looking good Leo! You gotta come by and show us the new turbo sometime

 

Unfortunatly since the torque/horsepower are at different scales and therefore do not all cross at 5252, the overlays don't mean much as far as spool difference and area under the curve are concerned.

Thank you for the other info though.

 

BTW, did RG do the tune for you?

 

nice numbers !!!!

 

c63 amg =303 whp,lol........it reads really really low your dyno,lol....pretty weird mustang should be bang on.....

after all this we have to admit that the stock turbo is really really good ......stock turbo = almost no lag at all ....so nice

 

Nice Gains!

 

Where did you get AWD loses 50% through drivetrain. It is closer to 15-25% as far as loss is concerned.

Nice gains

 

Just for clarification - stock cams right?

 

Thanks guys!

Yes.

Thanks for bringing it up, I didn't even notice that lol

The stock turbo is nice for low to mid range, but missing ALOT in the top end

What I mean should be dyno correction factor

Stock cams and motor.

 

damn, nice gains man! Hate to be the one to hammer this but keep us updated on how the SST behaves.

again, awesome car!

 

It has been really smooth so far with no issues, I have not encounter any slipperage yet even at this level.

 

Hey Leo,

Were the numbers SAE corrected ? I was just curious because it didn't say on your dynoplot.

The Mustang Dyno at RG reads about 14% lower than Dynapak so you are making 337whp 299TQ (estimation converted to dynapak numbers @ 25 psi). Nice gains, this didn't make me feel too bad because my EVO is not too far away from yours

 

Ben, I don't think MD dyno graphs says SAE on the plot, pretty sure they are corrected values though.

You may be right on the conversion on the whp, but i think the wtq on the MD may read even lower. I previously dyno'ed with my stock turbo setup with all my mods tuned at 26.5psi tapering to 21psi at Dynapak and put down 294whp and 310wtq.

Did you put down 355wtq as you sig stated? I thought it says 335wtq on your dyno Either way I am surprised on the torque you were putting down with your car.
What kind of boost/timing were you running to get those numbers? Were you running high octane gas?

 

Based on these numbers your math does not add up for calculated gains. I understand your point about the Dyno you used, but just curious how you calculated the gains? I am sure your MR must feel very powerful now! Thank you for posting the Car's results!
