Default Ams intake manifold

Anyone with an ams intake manifold on a gd?

Looking for either reversed or normal style ams intake manifold owners.

Just looking to see how much space is between it and the hood. If someone could do some measuring for me I would greatly appreciate it.

I want to run one reversed but it needs to clear the alternator. It states it wont work on the website. Just looking to see if it's possible to do with a spacer or using the normal manifold style in reverse with or without a spacer. Normally you would put the alternator in the ac position but I cant as I have a oil pump there.

Thank you

I have a normal style ams manifold. AMS is right in saying it won't work. If you take the normal style and reverse mount it, it will hit the a/c compressor, in your case the oil pump, as the runners are on an angle. And the throttle body would be pointing up towards the lower point of the hood. It's a pretty tall manifold as it is without any spacers.

Yea that's what I figured slash they said. Seems pretty dumb for these manifold companies to design these manifolds and not be able to clear the alternator.

Not really. If you want to have decent runner length and plenum volume, you quickly run out of space without doing two different models due to to the offset of the TB from the 'wall' of alternator and AC.

Both pw and ams have standard and reverse models of their intake neither can be used with the alternator in stock position. I understand the constraints but looking at the ams and how tall it is one would think if the reverse version aimed straight or up it could have. That being said im sure the advantages of doing it the way the did outweigh the draw backs of alternator mounting.

How many people have reversed manifolds and keep ac. You would think they would consider them and the 3 stage drysump(any more stages requires different mounting usually pump on pan)guys when designing. I mean aren't hard parkers and track guys gunna be the ones buying all these aftermarket manifolds

It's what happens when you don't have people that specialize in the customer base designing things. They were an Evo shop, and now a GTR shop. Everything else always seems half committed to. Not meaning to knock, just been watching them for a decade.

I'm sure one of these days I'll finally pop out a cast manifold.

For sure they have been teasing that manifold forever

You don't seem to be sharing the whole picture.
I see elsewhere that you have dry sump. So the pumps must be on top, thus you not wanting to move the alternator.
You just can't have it all unless you start making/modifying your own parts. Other options are move the alternator! A small alternator?
If you only consider off the shelf solutions you will surely get stuck.

I was going to cut the ams and rotate it up but then aluminati came out his twin injector tgvs so moved on to attempting the na manifold reversed. I've been looking at smaller alternators may try one of these http://www.jonesracingproducts.com/alt.html#al9101dns saw them in person at parts show they are the size of a fist.
