3.8TransAM

Well,

Looks like I will be getting myself a Stealthram when I can get my hands on the vortec version.

I dont see anything that doesnt look cut and dried for me to do when I install it except for the FPR.

Anyone do something different, relocate it, or find another one that works and is accesible without being a hassle?

Just looking for some ideas since I know I have around a mth for I can get a intake.

When I had the HSR AFPR on my car, it was easily accessable. It was literally right there pointing out from the rear of the fuel rail. It just bolts up if you get the adjustable fuel rail set.

Can u get to the distrib bolt to set the timing and do it without taking 2 hrs ? lol

Just trying to find out all the particulars.

Is the adjustabel reg. different in size/shape than the non adjustable?

AFAIK the regulators are both the same dimensions. I can reach my dist bolt fine, but I have one of those funky wrenches for it.

The distributor hold down is actually easier to get to than stock from my perspective anyway

Synapsis

True. There isn't a runner in the way. I bought the funky wrench when I had stock TPI on there, you could probably get to it with a universal on a regular socket with a HSR.

3.8TransAM

OK, that makes sense. I wasnt positive from pictures and I always forget to look on a friends car when I get the chance to see it lol.

Now I'm just waiting from someone to have them in stock again lol

check out my thread on hsr fuel rails. i got a reply with good pics of a better adj fpr and some info on getting it installed.

When I had HSR, I reached the dizzy hold down bolt with a regular 9/16 wrench. It was wayyy easier than with a TPI.

The stock AFPR is a piece of junk. Mine would not hold pressure and would let gas seep out, plus it was also a pain to get to. I bought a Kirban Performance AFPR (it's made for GN's) and it works wonderfully, but is still a pain to adjust. The distributor hold down bolt is real easy to get to now by using a 14 mm wrench with a dip.

Do you have part number? Got any pics of it installed?

I believe he's talking about this one.
Part #6547

You guys have me really worried about the one that came with my rails so I might just pick one of these up too.

I don't understand why the regulator would be hard to adjust.
Are you mounting them on the other side?
This is how I have mine setup to go in and it should be cake to adjust.

Believe the Holley instructions say to mount it with the adj'er pointing the other way, that is how I have mine installed and it sucks to adj, will give it the switcharu next time I have it apart.

What were they thinking ??

RSblkcam

I tried to mount it the way pictured but when you actually have the intake on, the distributor has to be squeezed in there with the return line arranged like that. I didn't want to take the chance of having a fuel line touching the distributor so I just arranged it the way Holley said via their instructions.

I dont have the HSR, I have the singleplane commander type intake, but it uses the same parts.

Anyway, the FPR had to go with the line OUT because it would hit the valve cover..

Its not too bad to adjust with a long flat head..

Those holley adj fuel reg. really do suck! Today I was adjusting the pressure back to 42 psi and after all that turning it went back to 35 psi. Thats it for me I getting another brand!

Rats!!!
Back to the drawing board.

RSblkcam

Have you tried reversing the fuel rails so that they enter/exit near the throttle body as opposed to the distributor? I read somewhere that somebody did it and it worked out well for them. You can't do that with the Kirban AFPR because it is too bulky, but the Holly AFPR may be small enough to work.

Just out of curiosity, what is the attraction of an AFPR (instead of nonadjustable)?

rsn932

You can increase and decrease the fuel pressure to increase or decrease the amount of gas that the injectors fire, which basically allows you to tune your engine richer or leaner depending on what it needs. If you burn your own PROMs, which I think is necessary if you are using the HSR anyway, they aren't really necessary.

So once you've got it tuned, you can't fiddle with it anyway, right?

rsn932

you could...but there wouldn't really be a reason to. it takes a long time to get it tuned perfectly anyway, so a little fiddling is almost always necessary.
