link for people with no google skillz

mustangs still read higher than DD by a bit, but the results are comparable as far as ramp and peak power go (within a few %).

Good find.

I find it interesting that they are already making application specific housings before they even have a full roll out of the std housing options though...

Hi all!   I've not really been active on this forum for some time and although I lurk in to read bits and pieces of interest I don't really think of this as a forum I'm part of but I once was and I di

Haha - yeah it could use some more boost Simon..  I'm sorry I've not put up Motec logs in the past for those who've wanted to see. Back at the time I did a bit of comparing because I did more or

It would be nice to see this option with a T4 TS IW housing on it.

Originally it was a consideration for my own project, right till I found they cancelled the plan for T4 TS IW housings on the smaller turbines.

Even if it were to make 450whp on 98 the response is excellent, we would all be out ordering gateless 6boob jobs me thinks.

There is some parallel dev I suspect, Cosworth were working on them before ANY options were available. And cheers for posting the link, I had been having issues with my browser and ended up with a "CBF, do it later" moment. I figured I'd said enough to give the proactive googlers something to hunt for :)

he is probably waiting till he gets some good results before posting anything :P

Geoff currently doesn't have a turbo on his R14. His car has been sitting in his shop since the Modified event last year.

The Blue R34 in Borg Warner's booth had an 8374 twin scroll in it. The results haven't been posted yet because the owner of that car has not put in on a dyno yet. There is also an RB26 that has the twin configuration on it with the EFR 6258's. Not sure if there are numbers on it yet either, but the biggest concern for most is that they DO NOT SHUFFLE. I've had a few twin turbo set ups on the RB26 and anything that could produce over 550whp seemed to "shuffle" (surge)... so that was good news.

I know that dyno reads notoriously LOW, and I think the single was found to have a boost leak which is why it wanted to drop boost up high. The torque curve looks nice on the twins, but I agree with Lithium we need more boost to see what they really do.

We're you hear that? I pulled the pics off GTROC, but there wasn't any other info.

I know the tuner, and know that dyno. I also know that those pulls were in 3rd gear, so it looks less impressive than a 4th gear pull. It's getting HOT in AZ so 4th gear pulls on that dyno really work the cars harder than necessary. I'm sure Geoff will post up when he gets a chance, he's up to his ass in the new race car build over there at Full Race.

      RB25DE NEO with Haltech ECU

      @GTSBoy This method was able to get readings of -10 to -2, so it looks like its monitoring.  Now I need to figure out why the vacuum on the line provided isn't alternating with manifold pressure.  I went with 2 lines that an RB25 tuner recommended but I'll get a longer hose and try directly off the back of the manifold.  He may have been used to OEM intake setups while I have a DBW setup that removed the MAF and IACV.

      I work at a car detailing and tinting shop called Quark which gets all manner of German cars in usually (mainly due to a contract with Mercedes Benz Kita Osaka, BMW Nishinomiya and others) but every once in a while something special comes in, like a fully restored 1972 HS30 Nissan Fairlady 240ZG... The shop owner had immediately started applying film to the windows as soon as it was in the shop so the interior was completely covered in towels and plastic sheets. But I could get a few photos of the engine bay which was restored like new. Such an amazing car to see in pristine condition in Japan these days.

      Duncan's V37.......race car?

      Was going to say the car pulls up nicely everywhere, especially going into that last long right hander before the main straight. Looks like a lot of fun.

      Noobie Stagea owner..

      By Turbodoc · Posted

      Hey Dave, welcome aboard! Good to see another soon-to-be Stagea owner here. The wagons are awesome — plenty of space, still got that Skyline DNA, and loads of potential if you’re into mods. Definitely post up pics when you get it, everyone here loves seeing new builds. What model/year are you looking at?
