I am gettin an afpr and I need some opinions on which one is the best. I have heard the TPIS one is good but some people said something on it breaks. I also have heard that holly's are really good but I dont know if I am remembering right. Any feedback would help a lot. Thanks.

 

Pick one, any one or make your own. The aftermarket dowsn't sell you a regulator so if yours is bad it won't help. All they send is the cover with a screw in it.

 

My Accel has a regulator in it.

 

The BEST AFPR by far is the Holley AFPR (yes, holley made something good). The reason I say this is because the adjustment "screw" is a flat, thin disc that is VERY easy to adjust. With "most" AFPR you have to use a wrench on the adjusting nut to adjust it and because of space limitation you can only turn about about 1/8 of a turn at a time. With the Holley AFPR you can adjust it with two fingers and turn it 1/4 or more turns at a time and not have to mess around with a wrench. I'm very glad I chose this one after watching my friend with his and seeing how much of a pain it is with a wrench.

 

I have a crane one right now. That bolt is a pain to reach. Next time I'm gonna get a Holley.

 

I bought mine from breathlessperformance and after getting in through I couldn't help but think I should just have made my own. It's so simple it's sickening.

So how about telling us how to make their own???

 

I would not buy the accel brand. Once the inside goes bad (as mine did) they will only sell you the entire unit. Not the regulator part. They rigged it so a stock FPR will not fit inside the accel case! I'd either make one or by the shell that uses a stock unit.

 

Rob P how long did your accel last? Mine only has 3000mi on it and you have me concerned.

 

here is a link to an article by vader. he is THE man!

The Holley unit is great. I had the TPIS one, it was a piece, the vac tube breaks off very easily and did not come with new spring or regulator seal. The Holley does come with a new everything, the vac tube is very strong and threaded in rather than pressed on like the TPIS unit. Its also very easy to adjust as mentioned earlier.

 

Go with holley. I searched over and over the board for AFPR. I've read BBK, Accel,TPIS,Crane the screw is too long and must be cut. I installed the holley last week, easy install, comes with everything needed. the flat disk makes it easy to adjust. The instructions tell you to loosen the disk all the way out, but I learned at this position it has 7psi, this may answer why some people say it hits the bottom of the plenum. After it is adjusted I have 1/4" of space between the two at 42psi

 

The Crane sucks, as the bolt is way too long. The Hypertech Billet one I have is pretty good, only thing is the vacum nipple is a bit lose, not leaking though.

 

I guess the Accel lasted quite some time. I'm really not sure if it is the inner parts or perhaps the gasket is sucking air.
