Those are both great kits. I'd like to have a Procharger myself, I just can't seem to find a package I'm happy with. Their piggy-back fuel pump isn't something I want to monkey with, and I'd like a custom tune at the very least since I can't find a place to get a dyno tune around here. The Paxton certainly is easier to just buy from Brenspeed. I like the BAP that kit comes with...

 

I hear ya, I go back and forth with all kits but I mainly just want something reliable. I am also looking at the roush m90 and just adding a pulley. Im sure that would give me the 425rwhp i'm looking for.

 

With the m90 and the roush tune you will still retain your ford warranty.

 

Only if its installed by an ASE certified mechanic...

The VMP 500hp kit for the M90 will get you to your 425.

 

Yeah I think im gonna go with the m90 AS OF NOW. Its not that expensive, can still retain your stock warranty, and will get me the hp im looking for.

 

It doesn't maintain your powertrain warranty. Roush replaces it with their own and it has limits, for seperate systems and aggregate total. It is available to read on the Roush website.

 

The M90 is a strong deal for $4400 (yatesperformance.com), as long as 370~rwhp out of the box, or ~425 rwhp is your target. I've not entirely written that one off the list, but as of now I'm probably shooting for the Paxton HO. I priced out the Whipple standard kit, and they want $4910 for it. Thats just a lot of money for a non-intercooled kit. Its a nice blower though...

 

what kind of 1/4 mile times have people been seeing with the m90?
