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.
Some good info, thanx. Some of the shortcomings of the AED Kit became apparent to me when I first saw the kit, however, they only seem minor and I consider what I'm about to do to it as simple upgrades.
First: I'm not crazy about the heatexchanger-mechanical waterpump and coolant resevoir. I'm thinking of a Cobra resevoir and a Afco Heat exchanger with twin electric fans, any advice. Or would you simply recommend a electric fan attached to the stock AED 24,000gvh heat exchanger? You mentioned the Lightning Bosch electic waterpump, do you have part numbers for this?
Second: I will keep the 30lb injectors and get the system dyno'd at Steeda which uses a Mustang Dyno with complete numbers including temperature, fuel pressure and boost pressure. If the injectors are maxed, then I'll upgrade to 40's. I know I can easily sell the injestors that came with the AED kit.
I'm not worried about the numbers this kit produces but I will eventually max out this kit including a built bottom end, P&
heads and VT Stage 1 blower cams. When thats done, I'm installing a Methonal Snaw Kit for additional HP at the track.
What spark plugs do you recommend. I know I need NGK-TR6's gapped at .035 but I can't find them anywhere.
Any advice.
