Hypertune 680x325x100 core.

Entry into a Nismo core.

What fuel pump do you have? What size is the return line? Is there any kinks in the return line? What size is the outlet of the reg? Knock off regs is just asking for trouble. It’s kind of important.

Johnny, isn’t the whole idea of a surge tank to have it full ALL THE TIME? Not 3/4, half sloppy around tank, empty at the end of the straight then turn into turn one, when you NEED IT! Why not just run twin intank pumps? Defeated the purpose of a surge tank IMO if it’s not full all the time. ? walbro 460 lift pump. The surge tank comes with -8 sized threads. Bit silly to go from -8 and pay for a a -8 to -6 adapter. Keep it -8 and put a bigger lift in it. You have 2x 460’s emptying the surge tank.

What if there is very little/no fuel coming back from the surge tank. Sensor gets no fuel flow, reading goes stupid, engine doesn’t know what ethanol content it is. Not a smart place for it IMO. Have seen it on another car and funnily enough it got moved.
-
Put a 1-2psi valve in the by pass. That way the sensor gets all the fuel it needs and as soon as there is a slight rise in pressure, the excess goes via the by pass.

Tapping after starting (hot or cold) - then goes away

I hope it’s going back on the dyno now that all the exhaust gas is making it to the snail and not exiting stage left before it! The “big turbo” won’t feel as big now. ? -
R32 Gtr Build In Usa

How long till the twins are put in the bin and the 8374 goes back on? -
Need a single. Don’t have to worry about equal length wanker junk. More power everywhere, better transient, just put one on it. Waste of money.

Hurry up and get the new gearbag! -
Mate send scotty an email I’m sure he’d be more than willing to clear things up for you .
-
Didn’t see that you asked me a question, mate. Bin the stock recirc valves. There is no reason why they should still be on the car. Put one of those turbosmart units on the comp cover, turn it all the way to hard and see what it does. ?

Away on holidays. Don’t give a shit. -
Can’t really put a pressure on it. How does the head flow? What cams? How restrictive is the cooler? The list goes on and on. Buy one, put it in, wire it up. It’s not expensive.
-
The 9180/0.92 is kind of retarded. If you want the power that the 91 mm compressor can flow/give, you’re not going to get there by choking up the turbine side. So now you have a larger compressor and turbine to turn making it lazier than it needs to be THEN won’t make the power because it’s choked. the 8374/1.05 makes much more sense. No, it won’t be lazy/laggy because of the larger AR rear. Big compressors and small AR rears “to chase response” DONT work.
-
@gzro The coppermix has gone. The OSG R3C replaced it.
-
^^^ Are you measuring exhaust manifold pressure? If it made the power of a 9180, does that make the 9180 redundant?

88 is out. -
Another vote for the 8374/1.05 especially on a smaller 2.6L. The OSG triple is a pleasure to drive. The pickup point is lowish, not grabby/bitey. Having had a Nismo coppermix for just on 10 years, I was quite hesitant about going to the OSG triple. Totally unnecessary. * Apprantly they did some changes at some point. Not sure when the change over was but it would have been before July 2015.

Same turbine wheel so it will all work.

8474 compressor update on a 2.2 Evo. Attatched is the 8374 and 8474 graphs.

True. But then you could just size injectors correctly and not flog the ass out of the pumps.
