why would you expect to loose top end with a larger TB? Loosing bottom end performance(low end torque) is what can be expected with a large TB

ya killin me man, ya killin me! i have 75mm tb and 75mm maf meter calib. for 24lb. i think i should go 80 or maybe 76mm maf. i dont think the same size is good either do you? and about the bikini contest. those chicks need to lose the zeros and get with the heros.[sm=smiley20.gif]

sry but not to be an *** but it seams no one ever reads the whole post. im asking about the maf being smaller than the TB. the TB has not changed. I swapped my 80 mm maf for my stocker because the 24's I had in the motor were to much. so as I say again will a maf that is smaller than the TB hurt performance. because I have hesitation problems, and I lost top end after I put the stock maf on, in theory this is true because you are restricting the incoming air. but I can not figure out my low rpm hesitation.

HAHA I know why do they want to be with someone that runs 4 and 6 cyl when they can have a man that runs 8 or larger, I will say I like the sound of a 8cyl, I hate the sound of a 10 cyl, and I would do anything to listen to a 12 cyl everyday. I want a ferrari 575 maranello what a car.

yea i would say to have a larger maf not the same size or smaller.

as the first 2 people said... YES this can cause a loss of performance

You asked a question in theory, therefore it would lead us to believe that you didn't change your maf yet. You state that you run a 70 mm tb with a stock maf, and lost top end, making it seem like you lost top end after you changed to a 70 mm tb. If you would have put

in, it wouldn't have been as confusing. I thought the same thing he did. So therefore no need for


edit* I felt like you were kinda getting snappy, so I had to defend the guy

i'd say that stock maf would hurt performance, it cant flow the air
that a tb of that size needs

http://www.mustangworks.com/articles...tionBlues.html see if theres anything in there that can help. i couldnt understand it lol.. but its alot of info on how mafs work and problems they can cause. worth a try. good luck.

thanks ikeybmg. Marx91 my main problem is I have a low rpm hesitation, and my throttle response sucks now. I don't know if you saw my post the other day but I asked the same question and got 0 response. I think since the Maf is smaller than the TB the Maf is not letting enough air into the intake tube and the motor is sucking more air then the Maf can calibrate fuel for and that is giving me my hesitation. I dunno that's why I asked. ricepatrol I did not ask a question in theory I stated it.
