Running more boost? Get rid of that leaking POS dump valve...
Hey Guys,
I have been trying to find what I thought sounded like a boost leak for a while. I thought it was at the manifold inlet, then I was thinking I blew out the gasket at the head. I finnaly found it to be the boost dump valve. I had originally plugged the outlet and it was ok. As time has gone on, it seemed like the turbo didn't spool as well and there was a different sound from the engine off boost. Rather than the nice whistle is was a whooshing sound. Anway, I found it to be leaking between the valve and manifold, so I siliconed the O-ring and that helped a bunch, but there was still noise. Upon closer inspection, it was leaking boost from the seam where it is assembled. I decided to remove it and installed a 1.5" rubber plumbing cap with clamp that I got from home depot. WOW what a difference. The turbo spools better than it ever has, and actually isn't too bad at all even with the large .63 a/r hot side I still have. This would be one of the first things I would remove if you plan to run more than stock boost! Jason

Or are you even from USA? Anyways, its consideres at N/A intake manifold is slightly better in terms of air flowing, BUT, since its turbo, it doesnt count like any after all. Im going to add IC too with N/A manifold. But tip: i dont know is there difference between the height of 200- and 700-series N/A intake manifolds, but ive fitted mine manifold from 200-series D6, and it is really close to bonnet, think i have to cut piece from my bonnet cover. Will see.

I have made some measurements and I think the 240 NA manifold mounted to a D24T in a 700 car will be very close indeed to the hood. Haven't actually mounted it yet but from what I can tell looking at my 240's intake and the hood clearance on my D24T cars, it will be a tight fit... maybe too tight. It will take a test-fit to know for sure. I will be going down that road at some point but I bet Jason will do it first...  Jason, 77volvo245 scored a bunch of parts off a 240 diesel in a junkyard near him -- might see if he could pick up the NA manifold for you?
