aftermarket MAF

it was actually like 96svt1nbe or something silly at first:shrug:
but thats really niether here nor there. the point is,unless you prove that is makes power its always going to be doubted. as the maf isnt the restriction in the intake tract. a unoptimized tb is...according to demon.

Well, logically, whichever has the smaller cross-sectional area will be the point of restriction. Has anyone actually made any measurements on this? :confused:
 
psht.... i was joking first of all. i really dont know or care how long you have been here. you do nothing that impresses me. second of all, running a larger MAF will never hurt the car. having it improperly tuned will hurt HP. i talked to hollyroller and he said that he got 2 tenths of a second consistently with the larger MAF housing. just today i put my pro flow on the car..... it'll do some kind of good with it on the car vs the stocker, when i get it tuned. you can't say that the aftermarket maf is worse than a stocker if you bolt it on with the calibration that came from the company. how do they know what your car needs to be set at from their factory? durr!

Exactly, it will boil down to the tuning as well... like I said, I didnt use the actual MAF sensor that came with mine, only the pipe, and felt a difference, and the 1/4 mile trips i made proved there was something to be gained in the upper end from it!
 
and your just the epitamy of impressivness...:rolleyes:
i'm not sure what the attitude and your cheap shots are proving...but they certainly don't help your credibility or argument about the maf. but i'm sure you dont care about what people online think of you,why would you...your "IT":help:
 
sorry dude, you the one saying "oh i've been here since 02" and all that. nobody really cares how long you've been here. how do i act like im "it" anyways? i hardly ever attack people like you but i make one sarcastic comment and you get all pissed. calm down man, lol.
 
i said i was here since 02 b/c people are always like "noob",and its annoying. when do i attack people? i spec. pointed my post at "harry" not tricker.

moving on...you guys say it add's gains,so prove it,harry's been talking about it for three years already.
i like to see old ceg myth's get busted anyways.:laugh:
 
After thinking about it, I must agree with TRicker. If the TB is what is restrictive, as 95pgt-t says, then opening up the MAF will most definitely NOT harm the numbers at all. It isn't possible. If the MAF IS restrictive, then opening it up would gain a bit with proper calibration and a tune as was stated. Just my $.02 :shrug:
 
tour96se. Lmao i thought u dropped off the face of the earth. .

Anyways back on track. You were the one who got a special tune for your sho-shop pipe because you hard your bend removed. You were so pissed that you spent all that money and you got nothing out of it:help: I never forgot about that. I always wondered what were you thinking throwing that money away. :help:

Tricker and me don't get along. But at least he's knowledgeable to understand a larger maf will net larger gains if tuned accurately. He doesn't need to be on here for years to prove his point.

Yet a stock maf based at 70mm is not accurate. Because the restriction actually makes the maf end up to be 53.7mm. Since our stock TB 65mm has the center shaft it also must be smaller. I haven't had time to do the math on it for an accurate tb MM. I see that it would be around a true 58-59mm.

So why do stock contours have a 60mm tb and 70mm maf?
Svt has 65mm tb and 70mm maf. Yet we increase the tb by half shafting it and not the maf.:shrug:

In the end why make the tb 62mm after halfshaft and leave the maf at 53.7mm?

The maf sounds like a bottle neck in the intake system to me.

thanks harrry. im not trying to start arguments. ive only been in the contour game for about three years now, but i have done some tearing into them. my initial statement was just a joke to tour96se. he's shared knowledge with many of us and it all seems to be accurate thus far.

anyways, i do agree. the only reason i changed my maf housing is because the maf wires are in a small tube on the pro flow housing, and the stock SVT housing has the center running through it. i do wonder why nobody has cut the center out and only left a little bit of aluminum around the MAF wires. i guess its easier to just go bigger. an untuned or improperly tuned maf of any size will make a car run like crap, however. i hope to see a small gain with my housing. if nothing, i get the nice polished look. ;)

I recommended it back in 2004. Look up my original 2 posts on the old forum. I have added a link for a write up on how to do this mod. You will see when i first joined i recommended the maf opt and tb opt. I got chewed out hardcore by demonsvt and others. Because i was new also:cool:

Enlarging the maf tube does nothing. We have conducted tests on drilling out a stock tube by enlarging it to its max. Then testing the fuel/air changes and nothing was different. Its the housing increase that changes fuel curves making the engine suffer in the fuel area. Your starving the engine of fuel. Thus creating a higher burn and maybe detonation which in return will create a spark hitting the top of the piston. Long term dmg will occur and a dent or hole will be present if it is not corrected.

I have always been a fan of an maf increase on all cars. Its this maf opt that needs to have a tune added to make sure your not depriving the engine of fuel.

Unless you have a real life fuel reader. You are able to adjust or watch if your engine is suffering at high rpms. And of course you would adjust your fuel needs accordingly.

i totally agree. i'm not going to run the car until it is tuned with the bigger TB and MAF. i do have a wideband so i can see fairly accurately if the car is in a dangerous AFR, but the reasoning for getting the bigger tb and maf is just to upgrade before i do a tune, so i don't have to go correct it later :)
 
i'm not arguing either..as i've never tested a proflow on this platform. in fact..you guys have pushed me into buying one just for testing purposes.
 
i do plan on doing some before and after dyno's of various parts that have been long rumored on these boards as worthless....i'm really wanting to try a 3l manifold too

Stazi had one while runing his turbo kit.

Good call on items to test. I think joey is going to cove this while having a 3L.

Do you still have a 2.5?
 
yeah... 2.5 i was talking to someone over on neco,and reading through their old threads. and it was mentioned that the split port 3l uim had better top end than the svt uim. people really dont attempt it b/c of the egr tube and some vac lines
