I will say it's been a long time getting it back on the road. After I did some damage with detonation to 2 of the pistons and rings from fuel pump problems with the A1000's, I figured I would pretty much go the whole way since I need at least 650RWHP for 200mph. Right after the car went in the shop, I found an aluminator block on Ebay for about 1/2 price of retail still in the crate. Arizona Dyno rebuilt the entire engine and popped it back in. The first problem we had was still the A1000's not statying consistent. After having Aeromotive check them and send them back, they still didn't work right so we got dual Walbro's. That solved one problem. Keep in mind I have a return system.
Next problem was the fuel rails were leaning out on one side. Had to replace those and feed them from both sides. During tuning, we ran into the Aeromotive regulator going from 40-50 lbs but it needs to go up to 57. We are ordering a Weldon unit to see if that fixes the problem. The curve starts going wacky above 5000 rpm's but with the Livernois heads, cam, and springs, it should spin to 7000. It's currently running 17lbs of boost. The only problem with that and 91 octane fuel i that without adding a couple gallons of 109 in the tank (20 gallon fuel cell), we have redline at 5000 and run 9 degrees of timing. That's still 500rwhp but I have to see what the mileage looks like with that setup. We may go down to 13-14 to get more timing.
Kieth and John at Arizona Dyno are spending many hours with this project but the results are amazing. Once it's finished, we now expect at least another 20hp or more with the curve straightened out and cleaned up on top. I also added 2000R brakes in front, wider tires, and with the 80 lb savings off the front end, the car should also work even better on the road track now.
