Would you lose the power steering completely if you mounted in the front of the engine bay? I'm thinking that power steering would be a preference to hang on to.

Mounting on or near the intake loses cruise and the strut bar. Cruise is no big deal; from what I'm familiar with MSPs, they don't have cruise either. Strut bar could be reconfigured to work.

Top mount I/C, kind of like the WRX?

I agree that the Jackson Focus unit is a bad one to emulate. Car and Driver did a road test on a supercharged Focus about a year ago. Jackson claimed something like 225hp, but the car was slower than the 170-hp SVT Focus. In fact, it couldn't even break the 8-second barrier to 60 miles per hour. Turns out the supercharger wasn't matched very well to the engine. There was a very narrow rpm range, where you'd get a tremendous amount of power. If I was anywhere near my giant collection of dog-eared magazines, I would let you know the date of the article plus more details.

I think thats a pretty respectable gain being non-intercooled. Add the header, cams, hi-flow DP and MP you're going to see some really good gains.

Maybe the way this should progress is to get this to a Stage I kit first, just to get the concept established and feasible. Once that's set, then you look at a Stage II with intercooling. Just a thought.

yeah, I was thinking about that but I'm a little more cautious. I do not want ANY kit to be made without intercooling of some kind. I feel everything safety/reliability oriented should be addressed first....then we'll worry aboout adding boost. I think this is where a lot of people get it wrong and pop stuff.....also a header will probably come in the kit....still checking though.

holy crap....their supercharged ZX3 is slower in the 1/4 mile than my stock P5?!?! What did he do wrong?!?! Will I find out in my own way?!?!

They said the M45 is only running 6psi...thats horrible it should at least be running 10psi...thats it's efficiency cross point...where it starts being counter-productive. I was hoping to run 6psi with the M62 if it works out.

6psi with MP62 would HAVE to be intercooled or liqui-cooled. Too much heat...detonation would be a given.

Also, I'm not a fan of the Eaton's after seeing what all is involved with making them work, but it may be the least intrusive design.

Link from Mazdamp3.com on a 2.0L Kit

www.boosthead.com

I don't know how much different the 626/Probe 2.0L is to ours, but the kit at least can provide a glimpse of what a intake mounted supercharger would look like on our cars.

I remember the headers for the Probe 2.0L were being made to fit our engines before any headers were available, so it should be close.

Just trying to help!

already looked into it...there's not as much clearance between the intake manifold/supercharger and the firewall.

Also, you would have to remove the strut bar and cruise control for this to even be close.

The only other thing I was thinking about was the possibility of making the kit without the supercharger itself, allowing the end user to source his/her own Charger. Its not viable for you as someone wanting to sell kits, but Eatons can be found on Ebay for great prices.

Just read your reply, and how bad is the clearance with the firewall? I'd gladly say goodbye to cruise and strut bar ( which could probably get modified ) for FI via a direct bolt on. Is the kit a straight fit aside from those issues?
