Has anyone ever used "Professional Products" brand throttle body? They are priced lower than other brands but are they any good?

Guys with Mustangs run them all the time and I haven't heard any complaints about them that have not been said about the other brands.

Im  ready to purchase a new TB and was just curious if they held up well.  For the price I may try one.

I've had three. I had a 70mm on my car some time ago, felt it was too big, so I sold it and bought a 65mm. I then upgraded the engine and bought another 70. Never an issue with them.

When I upgraded my intake system from an Edelbrock Performer RPM to the newer style  Edelbrock Performer RPM II, I changed to the Professional Products 75MM T/B and added an Anderson Ford Power Pipe and picked up almost 50 horse. The T/B has worked flawlessly and I have the polished version which looks good with the rest of the polished induction parts.

Eventually I'm swapping a Performer RPM II onto my Thunderbird. I just have a few more tweaks to try with the GT40 intake and if they don't work it's intake swap time. Plus the RPM II just looks cool.

I have the RPM II and unless you are going to run a stroker or twist a 302 to about 7,000 rpm I would suggest a different intake.  It was a dog compared to my TMoss ported Cobra upper and lower on my 306, I lost all kinds of low end torque and gained very little power under the curve with it.  With the 331 it has proven to be a better choice but its even better with a 347 from what I can tell with other guys running it with that combo.

The old saying of bigger is not always better definitely applied for me here.  The only reason I bought it was that I was going to build a stroker, I had the money, and I had a buyer for the Cobra upper and lower.

My plan for this year is to install a shift light so I can get accurate shifts at the track. I want to try some shift points between 5500-5800rpm and see what gets the best results. Then perhaps swap to another intake. I would realistically prefer a Performer RPM I but they are harder to find than a RPM II. I think the RPM I would be a good fit (only gives up a tiny bit of torque to the GT40 but has good gains above 5000rpm). I know the Typhoon is just a Chinese copy of the RPM I but I'd rather not run a Chinese intake on my engine.

Run a ported Cobra or Explorer intake as with your combo you will make more power than the Edelbrock RPM II.

But the RPM II looks cool. Isn't that what really matters ;).

If one goes and looks at the old Anderson Ford intake shoot out the GT40, Edelbrock Performer, and Trick Flow Street Heat intakes all make within 10hp and 10ft/lbs torque of each other. These are stock non-ported intakes. The original Edelbrock Performer RPM intake made about 5-10ft/lbs less torque under 3000rpm but about 15-20hp more above 5000rpm. Being that I have a 2800rpm stall converter and 3.73 gears in my car I'd gladly run the original RPM intake for the gain above 5000rpm and the faster revving. My car spends virtually no time under 3000rpm when accelerating, even on the street. The original RPM also shares the same runner cross section as the Performer which is why torque loss is much less than with the RPM II (the RPM II has a much larger runner cross section). If I could find an original RPM intake cheap I'd jump on it. If it didn't work out as I wanted I could always swap on a Performer upper and sell the RPM upper.

On another interesting note Tmoss has a 5.0 Mustang 'vert with GT40 heads, a small Crower cam, and a Systemax II intake. Seems like he should run a ported GT40 intake and his car should have no low end torque. When I asked him about it he said he really felt no noticeable torque loss with the Holley intake swapping from a GT40.
