They honestly aren't. there only rated 375HP at fly. at 7 psi, the Series II blowers will only out out about 320-330RWHP. Even with A LOT of work, you're lucky to get more than 400RWHP from then.

 

I got this from Mustang Monthly and MM&FF wrote the same thing I think.

"Some people assume that the Mach 1's four-valve engine is identical to the DOHC 4.6 used in the '01 Cobra. True and false. Basically, it's the same engine, except for the Mach 1, Team Mustang enhanced the performance with high-flow four-valve heads, higher compression, new cams (from the 5.4 Navigator, reportedly with the same lift as the '01 Cobra cams but with different overlap and duration), revised calibrations, and improved exhaust manifolds that are also port-matched to the heads. The result is, well, actually less advertised horsepower than the '01 Cobra--305 to 320--something that may be attributed to the Cobra's marketing status as the top-of-the-line performance Mustang"

 

Saleen also does cobra modles as well.

 

I'm not doubting you, but I've never seen or heard of them? The only one's I've ever seen on their website are all 2v's.

Maybe they have but for only specific years? I know in 04 they only did 2v's.

I was meaning 99-04 models. Weren't these all 2vs?

 

Not true Roush did make one Mach 1.

I have raced just a handful of them at the track and beat them all, but only because I got them off the line. With similar mod's to mine they would smoke me. With a good driver they can go high 12's stock. Just spray him and be done with it. All is fair in racing.

 

I think they only did them in 99 and 00, but I could be wrong. I have definitely seen them though, they're badass.

 

Yea, I saw a redfire Cobra with SALEEN kit, but I thought it was a replica..... maybe not?!
