Default More HP!

Well guys I have had my 08 GT with a Roush S/C for almost a year now and have a little money saved up. From what I've read it is a M80 installed by a dealership when it was first purchased and pypes exhaust. I'm not all that familiar with superchargers but am with programmers and fords in general. So my question is how much boost is this thing pushing? Can I bump it up with a pulley kit, and maybe a recommendation on a brand of kit. Would also like to be pointed in the right direction for a boost gauge. I'm not all that high on the air vent style. (Would like to keep it looking factory or a bit of a sleeper)

P.S.
I'm looking for a SCT programmer for my mustang. If your selling PM me and we can work something out!

Your help is much appreciated!!

I think you need to upgrade superchargers, there's not much room for improvement in those.

Well that's too bad. Looking at prices and I don't think I'm willing to make up the difference in the prices right now. Maybe just a good tune for now.

yeah i thought you had a roush, not just a roush s/c. but yeah a tune should help a bit, are you auto or manual?

I would recommend talking shop with one of these performance shops that can help. I know Brenspeed is/will be carrying the new Edelbrock S/C's and are one of the largest Roush dealers in the Country. Those guys would be happy to talk you through the specs. You're in OK so there is a full install shop 20 minutes south of Dallas that you could get it installed in, if you wanted to upgrade. Or do a custom Dyno tune.

I've never talked S/C with them but they have always taken plenty of time to explain any questions I had.

VMP tuning offers a 500 HP kit for the M90. Check it out if you haven't already.

I got the same m90 and brenspeed has tuned it perfectly. Call them for sure. With the stock tune your getting about 5 lbs of boost. A CAI, tune, headers, cams will all give you more power. The pulley kit is another option but it spins the blower so fast it becomes inefficient and suffers from heat soak. Call and educate yourself before you buy anything.
