What a busy-busy weekend, the shootout was huge this year. We must have had 500 people at the shop on Saturday. I heard everyone had a great time, I just worked. Can not believe how many cars I tuned in 3 days. The winner and runner up in EVO Eliminator (fastest EVO class) were both tuned by myself for the race, made me damn proud to see them do so well.

Anyway. Running into problems making huge power with the EVO. Many shops have already discovered them and found solutions. We stuck with our staged upgrades and it took us longer to get to the same problems.

Most recently our car made 548 whp on the dyno. On the road and on the track the car simply ran out of fuel pump. I looked into buying some solutions from other companies and didn't care much for the options. My brother being the problem solver he is came up with the solution in a matter of minutes. (Then rubbed in it my nose that it hadn't been solved sooner) We now have a single intank fuel pump that goes directly into the tank (with modifications) that will support in excess of 600 whp. We have actually made 608 whp with it with no nitrous already. We will need your fuel pump assembly either in advance to modify or we can supply you with a complete unit and charge a core fee of $250 until you do return yours. The pump and modifications will run $550. When you get it back just drop it into your tank.

We are currently running this with the stock fuel pressure regulator and no problems of over running it.

This brings me to the next modification that I think we are going to need. The regulator. This is going to be needed for high boost pressures to insure the fuel pressure continues to increase as boost levels get high.

Pruven performance has a nice regulator kit that they were willing to send us to try. Problem is it won't bolt on with the sheetmetal intake, only the stock intake. What we are going to do is offer theirs for stock intakes and we are having our own machined for the sheetmetals. No need for remote mounting, it will mount right to the rail.

Hopefully with this new fuel system in our car and the ton of information I gathered this weekend from Jason Seibels from AEM we should have a record setting EVO shortly.

R&D is coming to an end, time to put down some numbers........about time.

cool stuff, keep us posted

 

Congrats on solving the problem. Keep us posted!

 

will the stock lines have to be replaced with larger lines? How soon will this be available

 

The stock lines should be enough for well over 600 whp. I don't forsee any problems with them.

The fuel pump is ready now, the billet fuel pressure regulator parts are at the machine shop and they know they are a rush for us, so hopefully it won't take them too long.

David,

Are these avail. yet?

Will your regulator work with the stock intake as well or only with the sheetmetal? Any chance we could see your design?

 

We canned the idea actually. We ended up putting a complete fuel cell in the car.

The regulators are done actually. I missed that part of the question. There will be a picture of the new FPR kit up on our site today. Quality is what I have to say about it, real nice. Works with the sheetmetal or stock intake.
