First time on dyno after this winter's upgrades. Mods were Roush M90, CAI, (gears were there and don't add to hp, but sure add at the track) 360 RWHP. That seems right on track with Roush claim. They say 435 at flywheel. When all siphering is done (20% loss for auto) I figure the M90 & CAI give me 450 at the flywheel.
Of coarse I want more, but I'm pleased that I got what I paid for.

 

Congrats on the dyno numbers! I was looking at this same Roush blower but have decided to go with the Edelbrock E-Force. How did the install go? Did you do it yourself? Any tips on good/bad things about converting to a S/C system?

 

The install went great, I and a friend did it. Only good, no bad things about having a blown car. That is as long as you get your jollies with it legally. Getting tickets would suck big time.
I got my "Chrome" M90 while it was on sale $3899, that's what put me into a SC'er. And I'll never look back. The sound & power are awesome......
Note: I did not want a quiet blower, the whine/power is were it's at for me, and I got it in spades with the M90 and additional CAI.

Don't you just love it! I've got a Whipple S/C putting out 7 lbs. (according to Mustang dyno), 373 gears and two tunes. It's a vapor 2008 vert auto. On the dyno it got 380 RWHP on the 93 Octane tune, local tuner. I've got an X pipe with Magnaflow chambered. Sounds great. My biggest issue now is with stock tires it may or may not hook up. If it hooks up it hits second and smokes the tires. If it doesn't hook up first gear smokes. So I have to be real careful or it looks like your burnout picture.

 

I'm running Roush safe tune mine so far.
I have 4.10's and these tires for the track and best time so far is the 12.3 1/4 mile at 112 mph.
