I have built a supercharged Blackbirdengine for my Caterham. I have not used it very much and its not quite finished but it ran well at a recent trackday. I have a rather detailed buildthread where you can see how I did. http://www.cbrxx.com/engine-airbox-exhaust-fuel-delivery/17093-twinscrewsupercharger-blackbirdengine-11.html

I dont think I'm on the cbrxx forum, I certainly cant log in anyway!

is that just a direct drive from the crank to the charger? very interesting!

That seems to be my first big issue, getting the pulley shaft through the engine cover (its not central with the hole I already have) Looks like i'll need to make a whole new cover!
Unless anyone has any good ideas!

I cant get on that link you posted at the moment
Is yours an EFI engine? or carbs?

Fuel Injected engine Matt





Hovsta what bhp have you achieved? And what injectors at what fuel pressure ?

Im not finished with setup and tuning on my engine and have not measured power yet. My intention was to increase power with 50 % and that would mean 10-11 psi of boost. As I have seen claimed horsepower to be everything from 130 rwhp to the Caterham numbers of 170 hp, that could mean everything from 200-250 hp.

At the moment I use the original injectors and FPR. Injector dutycycle indicates that I need larger injectors. Until I get them I have lowered boost to 7psi.
