NZ AE85 - soon to be BEAMS powered

I had the same thing with a beams engine I used to have, it was horrible below 3000rpm, had to cruise round at a higher rpm to keep it drivable. I put it down to the light flywheel I had and a few other things. However put it on the dyno, and found out that my AFRs were all over the show and it was about 20hp down on power.

Fitted the factory airbox for the engine, and gained utter shitloads of bottom end power!

As in, 5th gear at 80kph, 2500rpm or so, put your foot down and would pull right off the clock no probs.

Quote:In saying that, this just made the scream that occurs at high revs that much sweeter! I'm surprised by the noticeable cam switch over at high revs. From what I've read, the continuously variable cam timing is supposed to be not noticeable on the beams (unlike the on/off Vtec), but I can certainly feel a distinct switch over on mine - and I love it!

I used to have the same thing as well, until I sorted out AFM issues... the car actually felt slower when it had 20hp more and a heap more bottom end, because it never had that surge of accelleration when the rpms picked up... But it sure was a hell of a lot more fun to drive!

I think if you get your car dynoed you'll most likely find that you'll be having AFR issues at low end, most likely because of airflow meter issues.

Such a pain in the arse!
