Thinking about buying the roush m90. Does anyone have experience with this supercharger? if so what are your thought? I am not sure if it will work well with my cams.

There's at least one guy over on FNSweet running the M90 with the 2.57 pulley, tune and Hot Rods. He claims 445hp to the wheels and has no complaints.

With the stock pulley and Roush tune you can expect 370 to 380 to the wheels.

where did you get yours? are you happy with it? Any issues with the stock clutch and transmission?

I got mine from Stage3 Motorsports however, Yates Performance and Blue Oval Industries have the kit for about $4,300.00 and I think BBR has it for $4,500.00.

I'm very happy with mine, the car drives like stock until you get to about 1/4 to 1/3 throttle then the boost kicks in and away you go. No issues with the clutch or transmission. I get about 16-17 MPG City and 22-23 on the highway. Not too much of sacrifice for the power output. The M90 has a sweet whine as well!

I have the M90 on my 10. Bought it at Yates for $4300 shipped and had it installed for $600. i love the blower. It't quiet at idle and screams at WOT. Like someone else said, you can feel the boost a bit at low speeds, but get around 2500 and the car flys. It's a blast drive and with the new price cuts this is hands down the best bang for the buck going for a blower right now. It's rated at 435 at the crank.

I didn't dyno my car and i am on the stock roush tune for warranty reasons. Several 427r's I have seen dyno sheets on put 380 to 390 to the ground with the same blower. The dealer claims a custom tune will get another 40 or so whp for it and you can get smaller pullies as mentioned. Basically this blower will put all the power the stock motor can take out if that's what you want. i really like how it looks like a factory part under the hood too. Check out my garage album if you want to see it. Only the 10 kit has that intake layout though.

Do you guys have a phone number for yates? I looked on their website and it says it is for the 2010. I am unsure if this will fit a 2008

ShaneM

No phone, email them via their contact form. i think the kit for 2010 is only for that year, but i thought they had kits for other years on there too. I think the reason its specific is because the wiring harness is plug and play for the 10 whereas the other years required some splicing. they actualyl drop ship directly from Roush, maybe they can match the price at least.

Thanks for the info guys! Would you do it again if you had the chance? Is it worth the money?

I talked to Justin at VMP and he says he can get 420 to 425 to the rear wheels on an M90 with his tune and different pulley. Considering stock internals for me..I won't go forged... I think this will be good enough.

ShaneM what is the warranty?? Just to 36k on the odometer right?

What did your roush tune put down? I know they claim 125 or so
