Im going to upgrade to a larger fast intake and TB over my LS6 setup. But to see some nice gains i would like to upgrade the lid and maf. Ive been doing some research and im going to go with the FTP high flow 104mm lid. What are my options for a larger MAF? I do not want to go with an GM 85mm. I have found this MAF http://www.powrmax.com/PowrMAF%20100.html but am unsure of its quality. I refuse to shell out 300 for the lingenfelter MAF. What are my options?

Haha I dont really see one then. Ive never heard of a powrmax anything. Your only option it seems like to me is to go with a SLP 85mm or a GM 85mm. Why dont you want to go with an GM 85mm?

104mm lid, 85mm maf, 102mm intake. I don't want the bottleneck

its not really a bottle neck though. That 85mm will support plenty of horsepower. The stock one is good up to like 500. If you were gonna buy an off the wall maf like that then I would ask your tuner what he thinks because he is gonna be the one who has to deal with it. If its a pain in the *** to tune and he charges by the hour and it takes him longer to tune it then youre spending more money. See what Im sayin.

Where do these guys get their infomation from?

I have a PowerMaf its pretty tough material.

The PowrMaf is using the OEM GM LS7 MAF card, its just installed in "his plastic housing"

The new GM MAF card is adaptable in a wide variety of vehicle appliactions.

It is just as easy to tune a 100mm MAF as a 85mm MAF

Texas Speed has a 100mm MAF (is using the card style maf sensor)
Lingenfelter has a 100mm MAF (dont know which sensor of the top of my head)
Tick Performance sales the PowrMaf 103/102mm MAF (is using the card style maf sensor)

You could make your own!

Since it seems you will be using a 102mm intake then the 100mm maf is best.

the only thing that is currently a issue is scaling the IAT that is used in the card maf is off about 15% I know HP Tuners already has a fix in the beta version for this, but is not out yet for the offical verison. But you can still use your factory IAT for now and then when the software verison is ready just wire in the other 2 wires to the card maf.

What is your setup, my 85mm maf ran out of signal at 6000 rpm. I think that I will just go with a SD tune and forget the maf.

^ best answer.

I have the FTP 104mm lid, TSP 100mm MAF, and FAST 102. My tuner hasn't fine tuned it yet and I'm still looking for a good solution for couplers.

What information exactly are you questioning?

Going out on a limb, probably this: 'Your only option it seems like to me is to go with a SLP 85mm or a GM 85mm.'

FWIW, this car is using a Powrmaf and making over 650 fwhp on a 427 LS2. Owner says it runs smoothly. see post #1113

This statement is what I was refering to, The PowrMaf is not a off the wall MAF, and tuning the SLP 85mm MAF has been beat to death on this forum
The SLP 85mm MAF is not ideal for tuning. The GM 85mm however is a good MAF to tune with. But in the OP's case I recommend the 100mm MAF.


Yup,

Hey Shevrolay I have replied to your other thread about the Elbow I used to for my install.
from thread FAST 102 and Meziere EWP Mock Up


and OP Goodluck on your install.

OP you know the 104mm lid necks down to a smaller size than the 85/98mm air lid right? 85/98mm FTP lids are the same size just FYI. If you get the 98mm FTP lid a 4" coupler will fit perfectly over the outside diameter of the lid. The 98mm lid also perfectly accepts the 85mm GM maf.. Going to the 104mm lid is just going to be more of a hassle and probably no more gains due to the fact that it necks down smaller than the 85/98mm lids. Just some options for you..

This is probably a question for FTP, but why would they market a 104mm lid and sell it as a smaller size? Not that i dont believe you, but this concept just seems silly to me.

So if the 104mm lid is actually smaller than the 98mm lid, then i would be better off buying the 98mm lid.

yea idk either man.. but Chrs1313 has measured it himself and stayed with the 85mm lid because it was larger.. And he's make 495 rwhp and huge tq from an LS1 running 9s I think now so I'd take his advice

This is very true I was pretty disappointed when I measured the two lids...believe it or not the 102 necks down tighter than the 85mm lid...the lids are identical besides the snouts...

The 104mm lid does not neck down any smaller than the 98mm lids. They are exactly the same except for the snouts. The snout on the 104mm lid is necked up 6mm to allow the 100mm MAF to slide right in. There is no room to make the lid any larger and still fit under the hood. The 104mm lid allows a 100mm MAF to be used with any adapters and matches up very nicely with the internal openings in the 104mm lid.

Here is a picture of the 104mm lid with a TSP 100mm MAF installed. You can see the opening line up perfectly for a smooth transition.

Both our lids have the largest internal volumes of any lids on the market.
