What are the stock maf limits?

na svt · 02-19-2013, 10:58 AM

In regards to...?

04torchedpony · 02-19-2013, 04:13 PM

Hp limits w 39# injectors. Wanting anywhere between 450-525whp on spray

Get a 90mm lightning MAF and install the Mach MAF's sensor.

04torchedpony · 02-19-2013, 04:33 PM

Thanks for your help!

Thanks for the help

musclemerc · 02-19-2013, 08:02 PM

if you do the 90mm MAF you will need to do the IAT mod.
*Cobra IAT sensor
*IAT Pigtail
*3/8" bung installed on your CAI

na svt · 02-19-2013, 08:36 PM

The Mach MAFs electronics can be inserted into the 90mm housing. Nothing else is needed.

I tried this and after trying to screw out one of the screws in the LMAF housing it just started spinning in the housing. Pretty sure it's trashed now.

Pry it out, then glue the insert back in.
Happens all the time.

Yup, a little epoxy fixes it right up, well that and cleaning the screw threads.

What glue to use?

I use the Zspar that I use on intakes, JB weld can also be used.

I've also repaired them by filing a slot in the OD of the insert, installing the insert and they drilling a small hole at the slot and then inserting a small nail whic ascts as a wedge.

a_bishop07 · 02-20-2013, 04:01 PM

dont think u need a 90mm to make that kinda power... i made 480 on spray with stock maf...

04Mach1FTW · 02-20-2013, 06:35 PM

your stock maf will NOT read properly at that level lol... Mine was very close to maxed out at 360 rwhp

EDIT:

Wasnt even thinking about the spray, just factory MAF limits

Brain · 02-20-2013, 08:04 PM

The nitrous is injected south of the MAF. I'm not understanding why you need to upgrade the MAF?

04torchedpony · 02-21-2013, 08:12 AM

Ya I'll be running a wet shot btw if that makes any difference.

a_bishop07 · 02-21-2013, 02:58 PM

wet shot here... and like i said 480whp. car runs great. ive sprayed multiple bottles through it.

blown03Mach1 · 02-21-2013, 07:20 PM

I ran stock MAF and diablo MAF.ia. My hp was 458 on a loaded dyno behind my P1.

04torchedpony · 02-21-2013, 07:42 PM

I may hang onto of the guy doesn't come through. A 100shot should net me close to 460-475whp and I'd love to spray a 175 shot later on.

311-420 · 02-21-2013, 10:38 PM

The extra fuel is already accounted for in the nozzle of a wet shot. No need to fool with the maf.

wouldnt this read off as the housing is bigger and the stock maf is calculating air flow based on the size of the housing that is came in vs the 90mm housing

Brain · 02-25-2013, 11:27 PM

A tune is required to compensate for a larger MAF.

04torchedpony · 02-26-2013, 08:37 AM

So what's the conclusion? Would I need a bigger maf for a 100-125 shot of spray or could I just stick with my stock one. Or do i need to see if my stock one is pegging or not when the time comes.

Brain · 02-27-2013, 02:31 PM

Stock. Fuel and air both enter the system through the nitrous injection. The MAF is not in the equation.
