Roush Phase 2 dyno results

[sysquella]

So got my 2015 dyno in and kinda feeling meh. Current stuff on car is
Stainless power long tubes
Gibson catback 3” with x pipe
Roush Phase 2 kit
Manual transmission


Ended up getting 635whp 548torque
I thought I would get more. I was tuned by dyno tune motor sports. First time ever doing a dyno so don’t know much. I know he copied a similar build before he ran my car. I know the Roush kit only comes with 47lb injectors, so maybe need bigger injectors.

You running a BAP or anything? I agree your fuel system is probably holding you back a lot.

 

[sysquella]

Yeah the phase 2 kit came with a boost a pump

 

[Notheryote]

Tuner should be able to tell you if you’re running out of fuel, although I suspect your injectors will hold you back either now or especially if you try to pulley down.

Sounds about right for the phase 2. Mine was around 640. Upgraded injectors, cooling system,, etc. to go beyond the phase 2 as strongly suggested by the tuner. At the time I remember that the math showed the 47’s to be nearing their limit

 

[Notheryote]

ID1050X should get you where you want if you have good fuel and can pulley down.

Alright. I'm currently on 93 octane and really just wanting to push 800hp to the crank. Would prefer not to go e85 since not a lot around me. I'll look into those injectors and pulley size. Believe I am running 80mm right now.

One thing I wish the roush supercharger did have was more whine.

 

[WhiteyDog]

Going with the 1050x's and bigger intake tube myself. Lund suggested both last time I tuned with him. I already have the BAP, IAT 2, and 170 Reische which he suggested last time as well.

 

[Notheryote]

Maybe check this out for more whine, otherwise you can make your own for a bit less.

If you want 800 at the crank, that’s 680 wheel. Just do ID1050x, VMP elbow and Twin 67mm TB. Added some LT headers and you should be there easy

800 wheel shouldn’t be a problem with the mentioned upgrades. You can read my signature for my setup but the tuner/VMP says I can go there with just another tune no problem but there’s always risk. I run a can of Torco in every tank as a safety margin. Heat becomes a problem and the original Roush intercooler is barely adequate for even their conservative tunes. I upgraded to an Adler radiator and an Afco intercooler and they’re doing a fine job of keeping temps lower.

Exactly this! My friend has that exact setup and is making 670whp. It made more but he is on the stock roush HE and it sucks. Once he addresses that he can turn it up abit more to the 680 or so mark.

I’m currently on a Roush Phase 2 on my Manual 17 GT and VMP tune. The end of May I’m getting the VMP 67mm Throttle Body, PMas 120mm Cold Air Intake, 56lb injectors, new plugs, 79mm pulley and getting dialed in with a dyno tune on 93 and 100 octane tune. I’ll post the dyno results after they are done. It should be 680-690rwhp on 93 and close to 750 on 100 octane.

Who is tuning the car? That makes a huge difference as well.
If you're on the stock Roush Phase 2 tune, it'll hold you back. Check with Palm Beach Dyno or VMP Performance. You'll make good power on pump 93.
Good luck and let us know how you do.
