does anyone know what the difference is between the granatelli 85mm maf pn 350330 and pn 350112??

the ONLY difference i could find is the 350330 is not 50 state legal. what makes it illegal? is there any difference in flow, hp, pcm tuning, etc etc?

 

anyone?

 

I wouldn't waste my money on it personally.

 

If they are anything like the LT1 MAFs, save your money. JUNK

 

i think one comes with a CARB sticker.

I dont think he was searching for opinions on it, just looking for the difference.

you can also call them for the answer, they have great customer service. 805-486-6644

 

The difference is you can either get a 350330 POS or a 350112 POS. It's just better to have choices when throwing money into a product that sucks.


But in all seriousness, please don't waste your money. There are people running 5 and 600rwhp cars with the stock MAF. If you're really just wanting to buy a MAF though, look into the Delphi 85mm or get a Z06 MAF from ebay. They will both have to be calibrated, however, and need a special adapater to fit our cars.

 

I forget the part # but I had the "make your car misfire and run like crap" GMAF. (I don't recommend it)

 

you'd think i touched a nerve. i was just wondering if it was like having a cat as opposed to an ory or something. one's legal and one's not but there's a difference in flow.

i read in another post that mti has recommended the 350330 on one car. they have a great rep and i trust them so why do you guys think they suck? do they not work well on a stock setup with no tune? i plan on tuning mine, which will not be stock

and what mafs do you guys recommend?

 

i hear lots of bad stuff, but mine works well. of course JR built my car and i doubt hed let a car with his name on it leave with issues.

id assume that the main issue here is the price/hp increase. GMS stuff is pricey, but i love this:
haha and GMS makes crap? it doesnt need to be calibrated nor doesit need an adaptor. haha

 

i would use a stock maf but i don't have one. the short block is being built so i'm gathering external engine parts. there is NO WAY i'm going to drive that car without a proper tune.

i've heard some good things about the granatelli maf. i'll see if i can get someone on the phone at granatelli tomorrow so i can ask em.

 

You would be better off buying a stocker off ebay or better yet IMO running a SD tune.

 

This is the reason Granatelli can sell MAF's, because of people like you that think you can just throw it on without tuning. I'm fairly lost as to how the GMAF not needing an adaptor means it's better quality than an OEM MAF. The Z06 MAF needs an adaptor b/c of the wiring differences from the Z06 to our cars. I guess if your only basis of quality is wiring differences, then yes, the 85mm Delphi/Z06 MAF is absolute crap. If you base quality on the fact that it's an OEM piece, can be much better and easily tuned, and won't just lean out your A/F for a couple extra ponies, then it's a different story.

I have had a granatelli MAF that the guy before me put on. It's crap. I speak from experience, not to mention the plethora of bad feedback on this MAF on the board. However, I really could care less who goes with what. Just trying to help people save some money and go with something that is cheaper and has a lot better tuneability. But, you can only lead a horse to water.

 

Hey guys, talked to Granatelli today. Dude was very cool and said that there wasn't a difference in flow or horsepower between the 350330 and the 350112. He said the difference was that the 350112 had to be tuned differently to be C.A.R.B. (california air resources board) approved along with the C.A.R.B. sticker, which is why the 350330 is cheaper.

He also said that the stock LS1 maf would work perfectly fine until about 500hp. But then he also admitted that the Granatelli 85mm LS1 maf also flows better and can make a few ponies over stock.

totally appreciate all the advice. sorry to hear that you guys had bad experiences. i plan on getting my engine tuned at mti and they've recommended the 350330 in the past and are familiar with them. i might give them a call soon also and see what they say.

 

Good luck. Let us know how it turns out.

 

it's not allowed carb approved b/c of the tune it sounds to the computer.

 

will do arctic. if it sucks and i have to get a stock maf, i have no problems with you guys saying i told you so. lol

 

save the 200, i got a full bolt on car and am about to go hci car and the stock maf is fine for me, check peoples part lists, most smart people just do full bolt ons, then tune, then go H/C/I or FI and do a speed density (MAF-less) tune, which is sweet

 

Newb time: So I could get an SD Tune and get rid of the MAF all together? Is that good for a DD?

 

SD isn't worth it for your power level and goals. It is possible to get it done, but you won't really benefit from it.
