What's the difference between the regular maf and super maf refurbished? I'm having maf issues (ruled out LH etc), car continues to accelerate to any rpm but very lumpy. Temp 2 was also checked and I could not find any vac leaks. Fuel pressure is at 60psi with the go go pedal pressed.

Thanks

A SuperMAF is a modified version of a MAF for 928s with power output over ~500hp, and some tuning is required to run it properly. A normal rebuilt MAF from Louie should work just fine in a stock 928.

I have no useful input Fred, but I truly love the look of your shark!

(Of course yours too Dan...)

Thanks Dan. That's the info I needed.

Thanks Ron, but mine's bigger that Dan

So now that I need to replace or rehab a 23 year old MAF, I'm torn between a MAF rebuild or go for the Alpha N (MAFless mod) from JDS. I can handle the install (so can anyone who's ever done a manifold refresh) but has anyone installed it and it's running great?

Jim Corenman has installed the ALpha-N on his GT, and it runs very well indeed. Been like that for a couple of years now.

Obviously the power is still limited by the stock intake.....

The race car in my avatar also has Aphha-N but it has ITBs and a stroker engine.......for the last year. Runs rtace cams but still has nice steady tickover, no problem iwith inlet reversion.

Chebrator on RL is fitting the Alpha-N to his race car, he's using BMW ITBs.....

Thanks John. I'm gonna make the change over if I can't find why my acceleration is so lumpy. I'm still performing diagnostics. as soon as I decide I'll make the call to Jim
