Thumbs up

Ha! I like that little pic, As for the reason for no turbo, I want to build something i can literally go out and beat the **** out of and not even have to look at the guages. Fot this i went with a fuel injection setup with no turbo. If you look closely there are no regular hoses. all braided with fittings and belts will be a double belt pulley for water and crank. Twin fuel pumps and a nice oversized 4.5 gallon sump tank with not one, but 2 huge 34 row oil coolers.

Huge is an understatement, HAHA. I'm still jealous though, very nice work. Can't wait to see what this thing will be able to do.

Exclamation Engine Broken In and installed in the car!!!

As of this past saturday, the engine was broken in nicely. Sounds Awsome and made real good torque on the engine dyno. I have to say that Carlos Lopez has come up with a really productive combination to make these 2 rotor pp engines make all this power. Now that the engine is in the car, we will be making the engine harness and finalizing the little things left to have this car on the homestead speedway for the July 14-16 farausa.com race. Slowly but surely after a little over a year. this project will be comming together.

Thanks to all for all your ideas and support
And a special Thanks to Carlos Lopez from CLR Motorsports for this awsome engine pakage he has put together.
And a big Thanks from the bottom of my heart to Al Delrisco From BMF Racing for all his fabrication and technical ideas that have made it possible to have this project become a reality.

It is going to need that much oil cooling? Damn real nice and clean though.

Those numbers are from his turbo car. There is no way an NA 2 rotor will put down 500rwhp

the more oil cooling, the better.


track cars have far greater cooling system demands than street cars, I don't think that's overkill.

maybe close though, those ARE pretty big :P

Even if it pulls 300+ whp on the dyno, I'm sure it will be peaky. If not, I will seriously consider dumping my single turbo to go 13B PP! Please post the dyno when you can.

PP's can make any where from 270 up to 350 depending on a few variables. Keep in mind that the 350 figure will come from an engine that shifts at 11k (pure drag engine). Very very peaky with virtually no REAL streetability in the low to mid range. It all depends on what you want out of the engine.

one thing that caught my eye was the full metal pipe from engine to radiator... i would think that any engine movement or vibration will break that pipe and destroy your pretty new engine in a hurry

Thumbs up Radiator Pipes

your right there is full aluminum pipe between the engine and radiator. but, if you look closer, you will also see Adel Wiggins clamps at these points. The clamps are used for these purposes where you need a tight yet flexible seal. they work with o-rings and will allow a work flex of about 1/4 inch. more than enough for a motor that has solid aluminum motor mounts bolted to 3/8 solid steel plates to the subframe.

Exclamation

The hatch was purchased on e-bay. you may have to do a good search for anyone who carries it or you may have to call to see if they have one on the way from outside the country, your best bet is to pay for it so that it secures that you will get it when they get here. my friend has been trying to find a CF hatch for his project now for almost 6 months. as for the Poly rear window, its made by FAL who are the same people who make flexalite fans. go to summit racing and get thier number there then call them for a price and a local dealer. i paid about 215.00 for mine but i heard they have gone up quite a bit since then.

I bought also the FAL from Summit;delivery took almost 2 months.
I bought windshield and side passenger Lexan from HRP World.
