Got a 9.2 compression 383 with a TC78 at 10psi and the EFI connection 24X conversion. Currently running in speed density and making 600hp and 600ft/lbs spinning to 6000rpm . My dyno tuner thinks I'm at the limit of a MAF, but I don't know. It runs alright, but I think it'll run a lot better using a MAF.

 

You'll be fine without it.

 

my friends 10 sec 4.8 truck is using the stock truck mafs

 

I bet his and the OP's are the different style MAFs.

 

Well, I have a 4" aluminum housing with the LS7 style sensor. Problem is my intake tubing is 3.5" so if I put the 4" maf sensor in there it'll have erratic readings. Also the iat sensor in my MAF is bad, so I just have the stock LT1 style IAT sensor for now.

 

we cut the wires off the truck one and put the iat in the intake behind the throttle.

this is the totally stock maf housing cut off the stock airbox lol

 

7 years ago my camaro made 760rwhp with a stock maf and factory map sensor. 600rwhp is no prob for a maf

 

I was making around 700rwhp+ with a MAF, but I was utilizing fueling from my methanol kit while in boost.

I wouldn't use a MAF on anything but a boosted Ford(ford seems to have boost and MAF's figured out) or a newer corvette or camaro(with the newer E-38 pcm).

 

Why

 

Why wouldn't it? I'm talking about part throttle driving and fuel economy wise. WOT shouldn't be any different.

 

If you have any issues with speed density you need to find a new tuner, it should drive great, get good gas mileage, and be fine without a maf!

 

then whats the benefit of switching to a 2/2.5/3 bar map sensor like everyone seems to do? Easier tuning?


...sorry for hijackish question.

 

The 99 LS1 in a 69 Camaro I worked on last year has a LS7 slot MAF in a 4" tube. If you play around in the code you can get it to read up to about 1000hp.

 

You will max a stock ls1 MAF in the 600whp area.....I know because I can go log my car and I max airflow at ~4500rpm's. Anything above this value must be fudged with PE or IFR tables or by some other means.

 

What about one of these?

Also, this is the type of MAF I have, but its aluminum.

I tried......even bought a fancy shmancy $450 dollar MAF, and it pegged immediately and I was like psssshhhhht. I do not have time to figure all that **** out. SD beh beh
