Saleen Series IV Supercharger

I purchased the new AED Eaton Rev 5 blower kit with intercooler and a 7way adjustable SCT chip set up for different settings.

I am shying away from the twin screw Autorotor blower until I start hearing some longivity stories on how well their holding up. However, I know my kit can be upgraded to the 2300AX blower from AED so I'll keep that in mind after I purchase a built motor with P&P heads and blower cams.

With some of the leaking problems some guys are experiencing hear in Toronto with their KB kits and only 18K on them I decided to stay away. They tell me that they've made many calls to KB with zero feedback. After 2 weeks of calling and numerous emails, they were finally instructed by email to call another company in Cali to rebuild the blower for $2000 Cdn!! Then after 3 weeks the blower was shipped to Toronto and they were dinged again by UPS for another $350 in brokerage fees. To me, that's not customer service!! I know the KB numbers are good but I wanted OEM reliability. Another website has a KB forum and many folks are having the oil leaking issues with very poor customer service. My opinion, if a 03/04 Cobra can put out 475rwhp and be reliable enough to travel across country then I can live with 375rwhp with the same reliability. Personal choice I guess.

Your kit is actually called a REV II (named after the manifold design). You've got one of their most recent kits by the sounds of it that came with the 5th Generation Eaton MP90. The difference between your blower and a standard 4th Gen MP90 are that the lobes with the 5th Gen units are Teflon coated to improve efficiency and the 4th Gen MP90's are not. The REV II is a great kit and will run head to head with a 1.7L KB up to about 9-10psi. Beyond that, the Eaton shows it's limitations by increasing discharge temps beyond that standard intercoolers control, forcing the computer to add fuel and pull timing to keep things for getting nasty. Allen Superchargers actually got a couple of short videos on their website of a Bullitt with one of their REV II kits on it and it dyno’s in and around the 390rwhp range. And even with so, so driving, the owner still managed to run 12.6 with it.

The AED kits do have a few flaws that myself and a few owners think should have been address and some in fact have. First off, the Eaton based kits come standard with 30lb/hr injectors. Not bad if you're only going to be running it with the 3" 6psi pulley, but you're really maxing them out at 9psi and beyond. Secondly, the REV I kit like mine comes with a 190lph fuel pump. Again, fine for 6psi, but fuel starvation problems may make themselves apparent up top when the blower is pullied for more boost. (I'll have to let you know with this one. Mines currently pullied to see 12-13psi. ) Third....and I'm not sure if they still use it or not, but earlier AED kits came equipped with a mechanical water pump for the intercooler system that bolts to the end of the engine water pump. Not bad when you're above 3,000RPM, but at idle, the slower rotation of the mechanical pump would cause heat soak issues. I like many other upgraded to the Ford Lightning’s Bosch electric pump. It flows much better all around that the mechanical unit and doesn't rob any horsepower in the process.

As I stated before, I've got the REV I kit, that in fact has the same manifold design as their Whipple based Race kit. The primary difference is the use of the 3rd Gen M90 (same as the ones used on the '94-'95 Thunderbird Supercoupe) over the 2300AX. I don't forsee a lot of problems with the 2300AX. It's been around for a few years now as is actually the same OEM unit used on the Ford GT. There's a guy over on tccoa (EECDOC) that's running one on his '95 Ford Thunderbird with ported heads and bolt-ons. At 15psi, he was seeing over 550rwhp to the wheels and was running 10.8's at 128mph. He's since pullied it for 18psi and is now running 10.5's at over 130mph. If the blower is able to push a nearly 4,000lb, IRS equipped MN12 into those kinds of times, imagine what it would do for a much lighter, solid axle Mustang.

The Kenne Bell issues are becoming more and more apparent I'm afraid. In the last month or so, I've seen the oil usage and issues with leaking come up half a dozen times now on a couple of different boards. It normally wouldn’t be that big of a deal to most of us (the Procharger guys have had them from time to time as well) and is probably easily remedied, but as you said it’s their next to non-existent customer service and in some cases total lack of response that’s really got these blower owners mad. Their customer service has always been the pits though…..nothing at all like Allen Engine's. Scott is always eager to answer questions and I and nobody else I know has ever had any negative dealings with him.

The shipping and brokerage fee's on the other hand is just something us Canadians have to deal with. Whenever I make a large purchase from the US, I usually just drive 3hrs to the border and pick it up on the US side of the border in person. This way, you only need to pay the sales tax on the shipment. Brokerage fee’s from the US are something that shipping companies love to tack on in order to make money and is nothing but a scam to the rest of us. Not to mention the shipping cost from going from just ones side of the border to the other are unreal.....double in most cases. You’ve even got to pay C.O.D charges on Credit Card purchases over a certain amount, when paying for the duties with most shipping companies, if you don’t call Canada customs in advance to let them know it’s on its way….whether the shipment is pre-paid or not. UPS nailed me with that one the last time, because instead of tacking it onto your credit card like they do the shipping amount, they pay it up front and then charged you a service fee for doing so when the package arrives. Canadians get hosed….through and through.
