I think you don't understand what I am trying to say, I suggest you do some googling.

I dont need to google anything. I am the one here that made record numbers on -5 turbos. I specifically asked YOU what is the restriction? What is the back pressure ratio on -5's? What is the back pressure ratio change when externally gated? What specifically is the advantage to externally gating these turbos on this engine?

Your motor will breathe, externally gate anything before the collector and you'll make more power.

It's not rocket science.

And congrats on your epic record achievements because it's a US dyno. I'm sure my corolla would make as much power as your setup too if it were on some inflated US dyno :)

Also, calm your farm.

congrats you managed to make 800 field mice power with -5s on an American dyno

That is assuming that anything after the collector is in fact a restriction... You have no data showing that it is or that an externally gated setup will benefit this specific application.

I would also like to point out that everyone seams to be laying the burden of proof on me. Has anyone here specifically dyno'd on a dynojet to say that it reads high?

And still hasnt seen the strip....

Car will see the strip. Just got the clutch sorted out. Now working on a tire rub issue.

If you love playing statistics wars, I heard the stock market is a fabulous place for that :)

What do statistics have to do with definitive measured data?

FYI - you still have not answered my question.

hint: its because you dont have the information to answer said question.

It is well known that dynojet number's are ALOT higher than dyno dynamics or mainline dynos here in Oz.

Run it up on a mustang dyno that will give us a far closer number.

Im sorry but on a stock head and stock cooler etc that your car has that power simply isn't possible!

Dynojets are around 15% higher than our dynos on average.

Don't need any data, proof is in the pudding.. piggaz's turbos were over worked, glowed probably redder than the sun, boost bled down up top.

I don't need to work for NASA to tell you that the housings are too small.

Anyhow, a couple of Nissan SR20s would pull a premium one week before race wars

Look, I was letting this thread sit till we ran the car at the track except I keep getting multiple emails a day with you jack holes cluttering up the tread. I am not stating anything until I run at the track.

So we are looking for high 130mph?

no, need at least 140mph.. Maatouks can do it with less powererererer.

Ok, so the turbos glowed and the boost dropped off...

Turbos glowing - excessive egt.... why?

Boost falls off - Compressor cant keep up (out of flow). Not related to exhaust housing restriction. If anything boost would remain at targeted level because the gases cant escape the engine quickly enough.

    • GTSBoy on your suggestion on another thread I had a look at those injectors and ended up getting them because of the quality.  Got the expensive ones.  
    • Hey guys been looking everywhere to try and find the correct gtr hood latch support part number but only found the first half and when I search with that number it sends me to an r34. The first part I found was 62515. If anyone could help me with the rest then I’d really appreciate it. Or if there’s some alternative hood latch support that would work even better cause I can’t find any for sale. (Searched on upgarage, partsouq,buyee,rhdjapan) 
    • If you've only done the upper control arms on the rear, AND you have changed their length (by more than about 1mm) to set the camber you want, then you will definitely need/want to install traction arms also. Adjusting the camber arms on their own WILL introduce bump steer and make the car unpleasant to drive. Most owners have no idea that their car could behave infinitely better than what they put up with. I'm not entirely sure what the Stageas need, but I am thinking that unless you have massive front spring rates and pretty soft rear springs, you have waaaay too much rear bar. Oversteer city, in my estimation. Combined with possible excessive bump steer from maladjusted arms, that could be a recipe for nastiness. ATR43SS2 is not a highflow. It is an outright replacement turbo. It's a little bit bigger than the largest highflow profile that Tao does. Probably a solid 300rwkW turbo where the bigger highflows will be about 30-40rwkW less. Nevertheless, we're only talking about ~300 rwkW, which is well within the abilities of the stock ECu to run with a Nistune on board. I would do so without hesitation - and I will be doing so when I get my finger out and actually get the injectors and AFM installed. But, if you would prefer to drop a whole lot more money on the ECU side, then I suspect you're looking at Haltech. The Haltech fanbois here will all spout on about all the available engine protection you can have, that you can't have with the Nistune option. And they're right. But it doesn't really come for free either. You will spend more money on extra sensors and the like, plus the work to install them. If the engine was built and therefore represented a big investment to protect, then I'd say definitely do it. If you view the current (and forever into the future) shortage of replacement engines as something to prompt similar protection, then also, do it. If you see a destroyed RB25 as an opportunity to put in a Mercedes or other V12 (like I kinda do)... then your perception of the risk/reward might differ. These are good injectors. You can also get a "better" set of the same with more flow matching, for more $$. 1000cc is where you will want to be. You will need an R35 AFM and adapter tube if you want to stay with Nistuned stock ECU. Otherwise, if going Haltech, you can ignore. As for intercooler. Just about anything will do. You're only talking about ~300rwkW. Just put a big core in there. Be aware that return flows do add significant pressure drop and will cost power and will make the turbo work harder to achieve the same goals. If you can manage a proper crossflow, do it. I'm keeping my very good return flow because I'm only expecting to be in the ~250rwkW range, and will live with whatever outcome I get.
    • I have a heap that i have collected if you want some authentic ones still. Pm me if your interested!
