Get ECU to log speed, rmp, boost and TPS over time, get to a speed and stand on the throttle. Ah, thought timing helped with that. That's why i pay someone to tune my car

Pfft, there's no fun in preserving anything though. Full boost as soon as possible, that's the only way!

Looks nice and clean now, but all the lines you need won't help i'm afraid. How are you pumbing into the gates, straight rubber or lines with fittings?

I'm hoping to do close to 500 with a plaz 76 but i'm realistic that it might run into issues. at that point not sure what i'll do though. Maybe cooler spray.

Just had a thought: you running this in the feed or return? If the pump is heating it would need feed, if the going through the rail and getting hot is would need return, i'd have thought?

There's not really much space there with the 33/34's because the fuel tank sits there now. If it were me i'd invest in PWM fuel control and stop the fuel from getting hot in the first place instead of trying to cool it down after. Easier said than done of course.

Pretty sure that's exactly what every one of the dyno companies out there said. And then set out to create it. And then there was one more dyno standard.

If it's not twin scroll then that's not too bad

Interesting, eoudhave thought it would have come on a bit sooner?

Soo..... http://www.nismo.co.jp/news_list/2016/news_flash/16014.html

Why the focus on 2 lines?

I'm just about to start getting quotes on a 3.5" system (stainless though); what's everyone's idea of a good muffler these days?

How do you people keep getting 200k's out of a tank on E85? I couldn't get less than 300, and that's without the super special VCT and the like.

Just dry sump it. Only way to be sure

But... Nismooooooooo!

The general concencus around here is that a 7670 would make at most 400kw but more likely high 300's, so not sure why you're thinking it wouldnt, I can't think of anyone saying that at all to be honest.

that is my gut feeling based off all i've ever read. Hopefully I'll go pick up my car running (on run in tune) when i get home ont he 14th of Feb.. so might have more first hand advice to say about it then... Also know someone up here doing a 7670 on theirs so will get to ride in that and get a somewhat comparison

Less power is is always more boring.... 7670 would give you some better response but would that be worth the cost to change to it? That's my gut feeling on it

What you want out of the car would probably be a better yardstick. One thing to remember about cams is you already had 246 duration ones in there, so its not like you've completely changed the engine

Did the engine have the heat exchanger on it when you took it apart? Because that fitting in the rear of the block isn't the one for having an oil heat exchanger... it should have a Y pipe for the feed, big one goes to cabin. The hole in the side of the thermostat housing is the return for the heat exchanger and cabin heater.

Turbo water comes out of the turbo side of the block. Is there a reason you're keeping the water to oil heat exchanger? I mean you've gone all out on a plenum so I'm assuming it's a serious car, but you don't have an air to oil cooler? Also need more images. I assume that the bit in your hand is the return? And there's ports on the plenum to plumb to it for a return?

800hp at the crank on the 76mm plazamaman. I plan to test that out soon to. Bigger cooler means more weight and i guess more pressure drop but maybe not?... Also means its harder to fit. Thing to keep in mind also is that bigger coolers act as a bigger heat sink, eg they're physically bigger chunks of metal that take longer to heat up. an 80C cooler is going to cool less effictivly than a 50C one. They both have the same frontal area so there's the same amount of air flowing through them, though obviously on a 100mm one there's an extra 30% length of fins for it to flow more so it could cool slightly more... but then that disturbs your air flow... End of the day will depend on your application. For a non extreme street car that's probably never going to do more than a social track day, a 76 will be fine for sure, ditto for aluminium radiator.

That sums it up quite nicely!

+1 plazamaman. get the 76mm one. Will keep your IAT down just fine, bigger is just more weight/restriction

I'm no drag racing expert but doesn't that time indicate your probably making less than 713hp? Wait no it's mph for power estimation isn't it?
