Want More Power?

[pylon500]

Just a quick note of a link I found doing some of my 'aero' type stuff;
http://www.crossflow.com/products/fi...ts/CF6-33.html
These guys are talking about getting 360hp from our EJ33's (230 normally) with a light weight turbo installation
Awsome stuff, but you need to rob a Bank first!

Looks good.

It is easy for them to site the turbo and plumbing behind the engine, as there is no gearbox in the way.

I note they lower the compression ratio to 9.5 to 1, and in the turbo section they quote 6 to 8 lbs psi boost pressure, and give examples based on 7 lbs psi. Handy to know this as a target figure.

Anyone wishing to convert now knows we can get 320 to 350 hp with this c/r and 8lbs of boost.

This aero set-up would not be optimised as a road engine. Aero engines run at 80 to 100% revs all the time, so torque and flexibility at lower revs are less important. This one is probably gutless till the turbo spools up.

I also note, even though they describe intercooling, there is no intercooler in the illustration. It must be the lower spec engine.

Because of our engine bay tightness, I am still a fan of adding a small supercharger and intercooler, which because of linear boost will make up at low revs for the torque and power lost from reducing the C/R. The reduced C/R will also allow use of regular unleaded, though naturally the car will be drinking more of it due to increased power output.

Yeah, the 2.5RS guys are getting about 260 bhp at 6-8 psi from their motors, so the EG33 should give about 340-350 bhp at the same psi. I've got a turbo calculator in my locker if you want to tinker with some numbers.

Where is Graham when we need him?
