Speed up my ABF Please

[Golf Loon]

Wow Thanks Gavin. Lots of good resources there.

They seem to say that the exhaust cam will help the ABF up top, but not acelleration. The opposite to what i want!

Well any 'hotter' cam swap will raise top end at the expense of torque

If you want to change the powerband and nothing else, do the 9a/PL cam and fit a vernier pulley.

The engine management won't like it, though, especially the OBD2 If you really want a chip, I still standby the fact that Powerchip are rubbish (dyno proven), so get a chip from DBilas or similar. They're cheaper, and they work

P.S. Good deals on 228mm 8lb alloy F/Ws in the US at the moment and a good time to buy with the US dollar so strong. I'd imagine the friction surface wears a lot faster than a hardened steel equivalent, though.

Does anyone engineer a hi-lift cam for the ABF? If you're after more torque without sacrificing drivability, this might be the go. I have played with hi-lift cams before, and was impressed. You probably wouldn't need to extend the duration too much (i later re-engineered the cam when i upgraded the carbies, and turned the car into a nightmare to drive around town... Oh well it was quick when I got stuck into it )

I don't know a lot about EFI engines, so if I'm talking out of my a$$ tell me

Cheers!
