Considering BBK 70 TB to Accufab 65 swap...opinions

[MH88'Notch]

Hi, I've got an 88 Mustang with an all Trickflow setup. Right now the car has a BBK/Edlebrock 70mm TB on it, which whistles and sticks a bit off idle. I was considering switching to a 65mm Accufab which I can get a really good deal on. I was thinking this might give a better throttle response and should still flow enough at WOT to give the same amount of power on my NA setup.

Just wanted some opinions...

I would do it in a heartbeat. The 65mm should be enough for what you have done anyway, despite what others are going to say.

you would be suprised what a 65mm will flow, I have seen some motors on a dyno pushing some nice #'s with a 65mm TB and probally still had some flow left. I have heard alot of good things about the ford racing TB no sticking or whistling, they come polished with sensor for around $170 brand new. either way you would be happy with the 65.

65mm good on all motor...Great on forced induction....bigger isnt always bettter (no matter what she says!!)

Smaller would get prolly more boost but bigger is going to flow more air. Just because your boost levels are lower doesnt mean you are making less power just saying....

I just don't see the logic in it. Why downgrade? Save your money, the “sticking” can be fixed with a good clean (TB cleaner) and idle set screw adjustment, and the whistle can be fixed by grinding down the sharp edges where the IAC ports come into the main flow path. I have also heard more than once that the throttle response thing is a myth. I’m surprised so many people are talking you into going smaller, but IMHO, stay with the 70.

I am not sure I have a 70mm eldebrock bbk TB I thought they was 2 different companies but mine says both on top. My whistles really loud when you hit the gas. Everyone thought I was supercharged. When I accually went SC it doesnt whislte at all. I took my CAI off and the whistle stopped for me anyways

Accufab makes the best quality throttle bodies.

Iv herd good things about the ford racing tb but i went down to make a purchase and i asked the guy if it came with the tps and he said no. Is this true

I checked the web and it looks like it does come with it.

within the power range the stock block can handle a 65mm will be fine...ill split mine with a 65MM TB.....
