GET THE FORD RACING THROTTLE BODY
September 09, 2011
The price tag caught my eye on this unit first: So cheap, right? Well there's a reason- It isn't a complete unit, 'some assembly required'. It requires parts off your stock throttle body, thereby rendering your stock TB useless. Not a big deal I suppose since you're upgrading, but I would have considered another product, one that is a 'bolt on' not a 'bolt on after you build it'.
Now the big problem: I did several upgrades all at once. This TB, a K/N CIA, UD Pulleys, and a Pypes Cat-back mid-muf exhaust system. Suddenly began having misfire issues @3k RPMs in 4th and 5th, when crusing or accelerating slowly. Not racing through it, just holding it at 3-3.5k in those 2 gears. Changed plugs. Changed coils. Changed injectors. Changed to the BBK CIA (more on this in a moment). Problem continued. Took it to my buddy's Ford dealership and ran a compression test- Ran at 100% on 6/8 cylinders, and the other 2 were so close, it might as well have been all 8. The tech was surprised at the results considering the vehicle has 100k miles on it. Said these were the best test results he'd seen on a car with that many miles. Just installed the Ford Racing Throttle 62mm Throttle body: Problem solved. I don't know why, don't ask me to explain it, but simple fact is, the problem was there, and now it's gone. I'm not a FR salesman, I'm a law student who wants his Mustang to run and sound like a SOB. Now it does. The throttle response with the new unit is better, and oh yeah, I can cruise @ 3k in 4th/5th gear without the engine stumbling all over itself. I'm willing to accept that maybe even it's my installer's fault, and he didn't move the parts over properly or something, but that goes to my first point: The FR Throttle Body came out of the box, went onto the car, and was bolted down, end of story.
Finally: If you read all that and say "What do you know, I'll make it work and save the $200", so be it, but keep this in mind: If you want a CIA as well, or already have one, make sure it's the BBK. The lip on this TB is bigger than the stock, and the K/N CIA ring is not made to fit it. Yes you can force it (like my installer did, and ended up cutting it, which made us have to get a new one which we were more careful with- but it never fit quite right hence changing to the BBK one during the above 'miss' problem), yes you can get other parts to make it work, but again to push the FR TB: I slipped the K/N ring on it, no problems. BBK built this unit to push their CIA as well. Fine, I'm all for making $$, but this unit needs two huge warning labels in red at the top of it's description: "Requires parts from existing stock TB" and "Use only BBK CIA". Considering the nature of this purchase, this is important info and should be conspicuously noted online. Goes to merchantability if you ask me.
At any rate, if you want to save $200 at the risk of dealing with trouble from day one, this is the unit for you. If you want a performance unit that arrives and is installed in less than 30min with no issue, spend the extra $$ and get the FR one.
