Intake and MAF ??

Hey guys, long time no see. Got alittle catching up to do. Does any of you know if anyone has a newer/ better intake for un NPI / SVO guys? And, has a good and dependable aftermarket MAF come out yet and possibly a really good intake tube?? The MAF and intake are th only two factory pieces I'm still running on my built motor. I have a tube, but looking for a better designed one.

Later.

The early bird may get the worm, but the second mouse gets the cheese!!!

yea RobertP can hook you up with a good intake tube....as far as MAFs go, depending on your BHP, an 80mm or 90mm Lightning/Cobra MAF is more than most will need...no need to go aftermarket.......if your engine is forced induction, and plan to make more than 500 RWHP, then an SCT BA-2600 or -3000 will support even more power.....or you can always add a MAFiA Xtender to a 2002-2004 mustang GT MAF to increase its range to support more power

I test fitted my main SCP pipe on the SVO car.It seemed to fit perfectly.But I don't think the down tube is useable.

Well, I've got a 90 LMAF when I rebuilt my motor. When I first put it on the car with my cold air tube, the car backfired through the tube a lot and the motor would sputter until I was over 3000 rpms. When I went to get the CAT dynoed, the MAF readings were all over the place--indicating to my dyno guy that the LMAF may have been bad, so we weren't able to dyno then. So I ended up putting the stock MAF back on the car and she ran great....got her dynoed and all was fairly good. Now the car, when I do drive her, does the same thing as it did with the 90 LMAF.

I think part of it is the MAF, and part of it is the tube. I know some of my problems have to do with the stock intake as well. This is my motor setup: 97 block bored .20 over, Manley H-beam rods, Diamond flat top pistons at 10.5:1 compression, 30# injectors, crank turned .20 under, SVO heads built by Renegade Racing, Comp Cams cams 232 intake/236 exhaust, SVO oil pump, Mark VIII oil pan, March UD pullies, 70mm trottle body, Kooks headers (3/4 length), MSD coil packs, 3.73 rear end, built tranny, and running true dual 2 1/2" exhaust with H-pipe, no cat. converters and Dyno Max Ultra Flo Mufflers (and YES---she is loud).

I know they have a somewhat better intake for the PI guys, just wondered if anyone knows of one for the NPI guys. If I can't find one, or they aint gonna make one, I'll just throw an SVO SC on her. I know there were some after market MAF's...but I remember guys not having much luck with them.

Well, thanks for the hepl guys....any other suggestions are welcomed. I'm just trying to get the CAT running alittle better until I can figure out what to do about the intake. I'll check into the tube you mentioned and go from there, thinking about the Trick Flo upper plenum and a 75mm throttle body also along with putting cat. converters back on for now too, if I can "fix" the MAF issue.

Was the car on a stock tune when you put the L-MAF in?You do realize you need a tune to run that MAF don't you?

my thoughts exactly....the EEC does not have self-learning logic when it comes to MAFs nor injectors in terms of knowing whats actually there......there is adaptation by way of the oxgen sensors, but it is very limited in scope and is no substitute at all for the EEC having both the correct MAF transfer function and the injector data.......you'll definitely need a tune to run them

It was tuned on the rebuilt/modified motor. When we were on the Dyno, the MAF readings were all over the place....not stable at all. Then I put the stock meter back on and went to have the CAT retuned. Got everything dialed in for about 262 HP with stock MAF and intake manifold. Not quite a year later, it starting acting up....like when the LMAF was on the car and then had other stuff in my life going on and didn't have time to mess with it until now.
