Really?

I'm sure it works just fine. The guy who's selling it to you ran some damn quick times and made gobs of power. If the price is right, I'd go for it.

Yeah. The same guy who's had all of his company's threads locked because he can't be bothered is going to give you an answer. The funny part is that he has logged on the forum very recently, but didn't bother to post a single word.

checked his pm's maybe? either way dampers on a return system are not neccesary, I've seen 3000hp cars with no dampers. You know whos gonna tell you that you need them? the guy selling them.

Eh, I've already spent more time looking than I wanted to.

Considering how many sources we've got for fuel rails (2, and one of them is GTM ) it's kind of a moot point.

Devil's advocate- Going from my (admittedly often faulty) memory, it was a VQ-specific issue that made the damper necessary. Someone shine the phunk-signal up in the sky. Maybe he'll explain. Or he'll tell me he has no idea what I'm on about and I'm remembering incorrectly. Either is a distinct possibility.

it's not vq specific, its rail harmonics. when the injeters open and close they create pressurewaves in the rail if there isn't enough volume and the waves stack up they can cause flow issues to the injector. it happens in all fuel rails, usually on smaller engines like the subarus because when you have 2 very large injectors in one tiny rail it is easy for them to effect each other. the 370 does not have a real issue with this if you want to double check why not call your tuner and ask him if there was a lean spot at a specific rpm, Usually its between 3-5k for about 500rpm on engines that get it, that he could not tune out by adding more fuel.

Edit: somebody should call cosworth and tell them their rals are garbage cuz they don't have dampers

cosmogirl is making a good choice. This is the system that powered my heavier car to 11.13"et.

I converted the car back to OEM stock after hurting it, because I DIDN'T have an oil system that was capable of 8500rpm, which I pressed looking for the tens. (Ducks for cover....)

It may have had 1000 miles on it max. Anyway, he's getting all that for less than 1/3 of what my invoice was, plus the fuel pod (Does the G37 and 370Z have the same?)

cosmogirl is a good egg. He's going to fly.

I'm aware that rail harmonics are not VQ specific. I'm saying that (again, going from memory from a post I can't seem to find) the VQ has an issue when the damper is removed.

The z can has metal struts not lastic and the level sensor is on a black mount. The big difference is the jet pump fittings between the 2 are different
