From fastspec2


I was being the devil's advocate here. Fastspec sums it up perfectly, the wastegate size can be smaller as the limits of the turbo are reached.

I am trying to provoke though...

when the bov vents it will vent metered air, causing the car to run rich whenever the bov opens. Sometimes, this can cause the car to flood out or stall.

looks great man. Tell these guys a little more about the setup huh?

I've always wanted to boost a P11, so I can be a baller like you. Oh well. I got cloth seats and no ac. What can you do.

car lo...

I would guess that the JWT is about 1800-2000 since it seems to have some geometric modification to it. The ACT feel stiffer, but my JWT held better... hmmmmm.

The current pp I have now feels just...

So why would running a lower psi make a larger gate a necessity? All the big guys running GT42R turbos would be running small gates because they are running 40psi right? Nope.

Well, the synapse gate is still way big compared to the TIAL. So I guess if you can stand the extra space being taken up by the WG then the synapse will work great. It is a better design. But packa...

I got 2 tial V38 for about $250 a piece iirc. Considering the packaging, I couldn't be happier. But then again, I'm one of the few that utilizes twin scroll.

The watercooled gates cost more? Nope. As far as I know all the new V38 have cooling ports. The price didn't change.

Apexi also used to make watercooled gates, but you had to spend a lot more mone...

I bought an all aluminum radiator a while back. It has a much higher fin count than my NX radiator. Same thickness. But it has GA16 1 1/16" inlet and outlet instead of the 1 3/8.

Still works like ...

CO2. it keeps the gate closed longer.

Remember a larger turbo means more intake flow, which means more exhaust flow, which means you will need a larger gate to keep from creeping.

The only way r...

Porsche also ran air-cooled motors longer than anyone else too. They ran air-cooled, laggy high-power designs well into the late '90s. Just because they live in the stone-age, doesn't mean it is be...

as long as you have a way to get all the air out of the system, you should be fine.

Come on ben, you didn't just throw the "basic wg" thread at me did you? :D

For ultimate durability the water-cooled center section is a must. Oil temps can still see coking temp inside the turbo w...

I run 22psi on .032. But I start getting break-up around 24psi. I lowered it to .028 and have never had an issue since. stock B14 ignition...er, b15 ignition lol. RR dizzy.

a 10x10x1.25 core isn't that big. I would go with something like this:

Air to Water Radiator

A cooler this size should be good enough for just about everything (no reservoir) except the sluttiest...

Why not just run an air-cooled motor? Cause we all know how well that works. Why would the GTR or any other factory turbo car use a water-cooled turbo if there weren't very strong advantages to dur...

Perhaps too many people had cracking issues like I did. I have the older style that is not water-cooled and I cracked the both of mine. This was probably done to prevent further issues like the one...

Right, what I am saying. There is no point to have both. If you had a small heat exchanger, then the larger capacity would be good. There is no point in having 2 gallons of water and a huge heat ex...

Yes, it is a new R35 GTR.

For what it's worth, I will be changing to my a/w setup shortly. It will just consist of a decent heat exchanger, a cheap straight through intercooler core, and a pump. We'll see how it works. I gu...

You won't need 2 gallons of coolant for an air/water with a large enough heat exchanger. No reservoir should be needed as long as your heat exchanger is of sufficient size.

I actually didn't ride the clutch at all. I dumped it at about 8000rpm, but it wasn't a really hard dump. I basically launched like I was trying to do a burnout. Which it did lol.

Cars up here ...

oh and so far Ive beaten the GTR, and two ZO6s. The ZO6 that ran last night ran a 12.6 @ 119 and had a intake setup. Otherwise pretty stock. This car is probably only putting 450 down at 22psi. Pul...

2.1 60' and I had a boost leak I was trying to find in the parking lot. Boost usually starts to hit really hard in 3rd and results in a ton of wheel spin at 5000rpm. Well, there was no wheel spin. ...

I guess the biggest difference between our runs is that I am at 5000ft. Corrected air density is like 10,000ft on my runs. That's like running 16-17psi at sea level or something like that. Not to m...
