Buying a Throttle Body.....opinions.....

1Slow90coupe · Mar 22, 2007

I am going to buy a throttle body and egr spacer for my car. I just got a new TFS Street upper/lower. I was thinking a 70MM would be right for me, and am looking at all the brands available. BBK, Edelbrock, Accufab, Professional Products. I see the P/P ones are a lot cheaper. Does anyone have experience with these?

Advice....

I've had the BBK and PP...no issues with either aside from the common TB whistle from both. 70mm will be fine unless your running some heavy duty product on that motor...big boost..big displacment type thing.

Just bought an Accufab... It's purdy nice

I had a BBK- It worked well too

Yeah 70mm will be plenty, unless you go with more cubes and boost but not one or the other.

They will all get you the air you need

i run a 70mm PP TB, looks good and works great with no problems. it has the fabled whistle everyone always says. lot of people hate, it but i personally like the whistle. sort of a cool sound.

Go 75mm if youre going to upgrade. The TFS has a 75mm opening so you match that opening to the size of the tb. Been there/done that, drove great! I dont think that at your level a tb is even needed though BUT if you must swap, 75 is the ticket.

I say go 75mm just in case you do decide to stroke it.

The 65mm would be plenty, I have read of sluggish throttle responce (slight) when you get a TB thats too big for your engine. But the intake has a75mm opening as i remember and you don't want to create turbulance in the intake track so thats what I would prolly get.

Accufab, a 70mm will work fine, my dads car had a 70mm Accufab and it had good throttle response and the TB was a nice piece!

i bought BBK's 70mm TB looks nice, but cost me like $580.....maybe because it had their new intake manifold attached to it.

If your gonna buy one, do it right. ACCUFAB. Thats what I have and the quality is incredible. no whistles, no problems. nothing falling appart.

I'm happy with my Edelbrock TB & EGR spacer. Pic

PP 70mm here and no problems

Flavadave4 · Mar 22, 2007

I just got the polished 65mm TB and EGR from Professional Products and it looks like a really nice unit.

I like the idea of a 65mm too, not sure if you can still get them from Ford Racing anymore.

70mm all the way

Oh yeah, I also have an original 93 Cobra 65mm unit, and it works well on my car!

I just read this month's 5.0 mustang and FF. They did a stock setup. Where they changed the cam, ported the heads and put on a bigger throttle body. They made 380 on the dyno.

I'll have to read that article, there has to be something you are leaving out
