Up-date on this engine project. Well I was a little concerned about these blowers being any where close to enough. The customer wanted us to try them so we did. The engine made 750HP without the blowers at 7500 rpms and about 630 ft/lbe of torque. This being a 8.5 to 1 engine with pretty small camshafts. The engine just is to big for these blowrs and the heads just flow to much. With the blowers on it made about the same HP at about 748 or so but the torque jumped to 700 ft/lbs but the max power was at 5700 rpms. The engine then needs more air than these blowers can provide. They only make about 3 PSI and then fall of.
Talked with the customer about all of this and he wants to try some larger blowers which is the only way it will make more power. If we can get a pair of blowers that will supply the engine and keep up with the air it is moving and make power all the way to about 7500 rpms it could get pretty interesting. The 1000HP should be real easy with the right blowers and still be very streetable. The engine idles on 700 rpms and runs like a top other than it not getting enough air from these units.
It is going in a Kirkham so I not sure what he will do with the extra power but we will try to do what the customer wants. It will be cool if we can get the new blowers to actual fit in the car.
