hey fellas i picked up a 70mm bbk throttle body with matching egr spacer for 80 bucks, i installed it and at idle it whistles. when you give it gas and the butterfly it stops.

also i got a larger, dont know what size, maf housing. it loooks like for a 94 or 95 cause it dosnt mount like mine, and you bolt something to it on the inlet side. can i use this and what part do i need to be able to mount my filter to it, thanks guys

i've heard that some bbk throttle bodies do that. you can drill a hole in it and it'll solve the problem. i think fivepointohh did it to his so you'd have to pm him. I assume you have the maf for sn95's so you need the elbow adapter, check ebay.

My 70mm Summit TB whistles at 1/2 throttle, sounds like a turbo..

I make people **** their heads when I accelerate briskly, since it sounds like it spools with my RPMs

id also look into making sure that maf is calibrated for your size injectors ..

yeah but it does get annoting. the throttle b osy itself is great, much better throttle respnse.

My sensor is calibrated for 19lbs, do you have to get a special housing for 19lbs too. i thought it was just the sensor but im not for sure?

yea, i have a BBK 70mm throttle body and EGR and about 1/2 throttle it whistles, exhaust is much to loud to hear it now-a-days. seems to be louder when its cold out.


ive heard taking it apart and smoothing out where it meets the IAC and the holes or w/e for the air to flow into the IAC to almost a polished look will make it stop.


i dont mind it, and sence my girlfriend is so easy to entertain she giggles and carrys on everytime she hears it. "oooooh, the wistle! i heard it! did you!" "yeeees Becky, i heard it."

lol
