Beast from the East! Project S483
#28
So it's been some time since I did an update to this thread. It's time for an update. The most recent changes to her was a new engine, and exhaust system. The reason for the new engine was a sticking injector caused the premature failure of a Oil Control Ring O-ring. This time around I decided to build the engine myself. I started by changing the port work. The previous ports were not to my liking so I dove into that. Changing the port work to my own.
Here is a picture where you can see the previous port work compared to mine.
Then I cleaned the Water Seal landings and you can really get some dirt out!
Time for some paint.
Then I built the rotors with new springs/seals. Just because, why not its apart. Then I assembled it.
Here's a little sneak peek at what else changed, she went from one disc to three with some help from Exedy
Here she is installed with the Goopy Scatter Shield

So It finally came time to strap her down. The Dyno we used was in a V8 shop. Filled with V8 guys around a supercharged mustang. They pushed it off and we rolled on. Wilmer was the tuner and I had Jim from JPR drive her on the dyno. So we are all clear this is on E85 from the gas station. The first pull we did, we decided to turn off the boost controller and let her make a run on gate pressure. So the gates opened up at 21lbs and she laid down 551whp.
Then we turned the boost controller on turned it to 20% increase which actually lowered the boost to 19lbs. After making a couple increase's on the controller we started to pick up boost after the first couple dyno pulls. On the 6th pull we made 548 whp. Turned her up some more and got the boost up to 25lbs and she laid down 704whp! We decided to turn it up a little more..
She hit 30lbs on that pull. She still had more to go but wanted to keep the stock trans in one piece. 839SAE HP or 867STD HP your choice. Not sure if this is the record for a 2 rotor on pump E85, I couldn't find any other dyno sheets any higher. To say the least I am ecstatic the engine performed flawlessly. I have to give a shout out to my Old Man for teaching me everything I know about anything with an engine, Jim from JPR for all the help over the years and Wilmer for tuning her to perfection.

To be honest with you I'm not sure. The IAT sensor is mounted to the firewall. I can tell you that right after the 839hp dyno run I was able to put my hand on the lower intake manifold and hold it there. The system works very well dispersing heat. Once the ice was put into the system the Intercooler Core was sweating it was so cold.

Just wondering what is your base fuel pressure set at and what type and how many injectors are you running? I have the same Eliminator pump and people say they don't like high pressure. I'm also on e85 and run 4 bosch 160lb white top injectors but I'm at 24lbs boost with base pressure set at 55psi. Great numbers and gives me hope with my setup.
