Thanks for all the information provided thus far. I wish someone with an actual Saleen with the same blower would chime in on their numbers with cams; there has to be someone out there.

There was a guy at corral.net. Going to be hard to find people because that blower wasn't very popular.

Any more information that, or are you referring to the link and guy above in this thread?

Good cam for Saleen blower car? - Corral Forums

I found this; looks like another believer in the Houston cam...

[jivepepper]

The S292 cam was the first great blower ground cam to come out. That's when you could only get them in regrinds meaning you sent in your cams and they reground them. All the big cam companies just basically make copies of these now with small changes in advance and lift. The orginal S292 cam came with 531 lift and the R292 has 550 now. I made peak power to 6800 rpm withe S292 and still was above 650hp at 7K. I'm sure the R292 could see peak power above 7k with the right setup. The nice thing about the S292 was it made power at lower rpm when my setup was simple and still does when I turned it up.

The S292 cams does fair better with centrifuge SCs but also works well with roots style. But there might be better choices out there for the roots.

I have never seen em with a roots/twin screw blower...do you know of any? I know MPH makes cams specifically for KB blowers but Tim wont give up the specs on them so I refuse to buy them, now, or when the time comes lol

Of course you must have modded springs/retainers to be revving that high.

would it just be better to upgrade to the M112 blower?

[GTRACER88]

It would be better to take the saleen blower off and go a different route. I didn't read it was saleen. They really aren't that great. Take it off, sell it and go centri or turbo. My 2 cents. There is also nothing wrong with the s292 cams, I just wouldn't buy anything from them again. That's all.

[LAWNDART02]

To the OP, I believe you could gain some efficiancy with different cams, more so with ported heads+cams, you may see less boost (pressure measure) but make more power if the top end flows better, using the air better with the current pully setup.
Would be less $$ than a new blower, but not by much.

+1, look into other blower options (m112) if you have the means..

Is the exhaust stock? Might free up a bit more there with an O/R x-pipe & headers. Won't get you to 400, but it would most likely make more for you than on a N/A car.

[jonwrong]

As I understand it, swapping an M112 onto a GT is a lot of work. I have researched if swapping to an M112 blower is an easy switch if you are already running an M90 (Saleen blower) with no real results. Anyone is free to chime in on that issue. If so, that's a super easy fix to get to 400. As I see it, the M90 is going to pump what it can pump regardless; no doubt the cams will give some overall increase and more under the curve. Based on what I read and my overall automotive experience, I don't know if another 50whp is there.

The car has a full steeda exhaust and BBK long tube headers. Obviously, adding a centri charger is optimal for air intake temps, boost, etc. However, there is a lot to that. Most likely, I would want a front mount, which gets into the piping, etc. Plus the limits of the stock block seem to be 425 to 450whp, and I have no desire to start building it at this point. I have also been reading that 8-9 psi is really what the limit should be, so I am not sure if a smaller pulley is a great idea since I have 9 psi now. I would be very interested to know if any traditional blowers bolt right on as the M90 is now. And again, someone with the same setup that can report numbers and improvements with cams would be ideal. I cammed my old 2.0 turbo sentra and went from 200whp to 255whp even with seeing a boost drop of 5 psi by peak HP, so with lower held pressure, I know cams can make an increase. I am just not sure it's worthwhile; cams are cheap enough and labor (mine) is free. Thanks again for all the feedback!

When I had stock heads and intake I ran the S292 cams to 6400 with the stock valve train/springs and made 515 @ 12.5psi on the dyno. I ran them to 6600 at the track for 2 years. Should all people do this? probably not, but it worked for me.

Best run with that set up was a 11.27 @ 130.69, on a stock suspension and 315 17" dr's on 17x10.5" Cobra R's in back and a 17x9" with 255's in the front in cold air and negative DA. at 550' track.

My best now with added power and about the same set up except lowers and uppers and tubular k-member is a 11.10 @ 133.8x. That was the 638 tune in hot summer air at a 1350" track. The 315 dr's are just useless now. I also need my suspension components adjusted correctly because 60's were actually worse.

I HATE Houston Performance more than any 8 people on this planet but their blower cams are definitely right! Thats about it. Everyone that works their is goofy and dont know shit! Most shops have big badass cars, some TT'd and some blown, but this joke of a place had neither. They had a CAI on one, One was wrecked (prolly the cobra they totalled on a test drive and then told the customer they were NOT going to be responsible). Just a bunch of shitty cars. The most horsepower in there entire shop was my car and thats not saying alot!

It's not the same shop that it was. Plus they have had some fast cars in the past. You had a bad experience, but most haven't. Sorry to hear it, and I must admit I've been hearing bad reports more frequently..

MPH makes great products and great service in most cases as long as you have deep pockets. But if you shop around you can do just as well for a lot less.

Just like my bad experience dealing with MPH, like being hung up on by Rhonda Barth Tim's wife who is also co owner of MPH. Just because I had a weird noise in the my BAP and wanted her to contact KB in my behalf because I couldn't get through after several days and it was only about 4 months old. She said what the hell do you want me to do? and just hung up on me.

Then several months later I was banned because someone asked what I thought of my ebay intercooler. I said I liked and it looked just like what MPH was selling. At first just my IP was blocked so I had to use either use another comp or a proxy server to log on. They didn't even tell me are warn me. Just wanted me to think the site was experiencing problems because after a short time I could log in normally. At first I bought it. They did it that way because I didn't do anything wrong and was hoping I would just go away. I figured I've been going there since the beginning so I helped to build that site and I was customer.. I had just made more power than they did with less expensive parts and was bad for business. I never said bad about the company and only talk to people about my setup if they PM'ed me,

But then they banned my user name all together. Since I mentioned buying the IC on ebay. Even though I didn't mention a vendor or mention a price they considered that advertising someone else's product, and banned me for that.

Thanks for all the tips. I have some some more searching on other boards with some pretty good luck. No other blowers really bolt onto the Saleen mani and blower kit. It seems my biggest power robber is the heat because the stock Saleen exchanger allows 30% or more air to pass through completely uncooled. I am in the process of fixing this and adding an idler pulley which all but stops belt slippage and deflection. I think this will get me pretty close to 400whp on the stock Saleen blower (A slightly larger modified M90).

[jivepepper]

Some cams might get you there if you fix the gap in the manifold.
