ATR43 SS-2 Rb25det Stagea. Externally gated from stock exhaust manifold E85 fuel. Final result of 356rwkws @ 22psi on Dyna dynamic dyno:

Further testing and evaluation on the SS2.5 Alpha turbocharger, now using an 600x300x68mm tube n fine front mount cooler. I've attached two photos, note the tubing size inside the aftermarket cooler and factory cooler.



Aftermarket cooler:

Stock cooler:

Using the new intercooler, boost tapering issue was resolved to some extend and the same turbocharger managed to pickup more power. Cooling ability however is not as good as standard, under comparison my intake temp rise by 10 degrees. I will be fitting an thicker 600x300x100mm cooler for further evaluations coming week.


Turbocharger wise, it is matching factory N1's responds but a lot more power. Pretty good to drive at this stage.



ATR43SS2.5 Alpha, externally gated on pump 98 fuel. Peek 330awkws:

Vs stock cooler using the same turbo:

In conclusion based on test result, the factory GTR intercooler is only good for up to 320rwkws on pump fuel, for upgrade, I would be recommending a good cooler that has a core size of 600x300x100mm.

All three GTR coolers are different, the 33 is best for cooling efficiency but worst for outright flow

My 105mm ARC cooler ( the best in the business) is about 4-6deg hotter then the factory 34 cooler but will happierly flow 1000hp

As I mentioned to Tao yesterday, Daz has made 500kw on a stock cooler and is heading for more. Not sure yet if he plans to upgrade his cooler this time around.

Yeah Ive heard of 450kw before

It isn't stock, it's 90 mm thick.

Weird that they're all different. How does the 32 cooler go?

And for people whom are switching to the ID 1000 injectors. The resister pack made for OEM injectors has to be removed. Big thanks for M35scotty on solving this issue yesterday. I believe he has some technical details to share.

The 32 is the best for flow but worst for efficiency, it is extrude honed and doesn't have the little fine fins inside the runners

You can tell the difference between 32 and 33 by the front of the runners, the 33 has a grove that runs along the runner which the 32 doesn't

That is something very simple and well known, simple cut the resistor off and solder the seven wires together then a bit of heat shrink and electrical tape and bingo high imp injectors working

One of his injectors had stopped working, after testing it I realised he hadn't cut the resistor pack off, one resistor had blown taking the power from that injector.

The resistor pack was much hotter than usual. Obviously it runs fine on the Haltech without modification, but overloads the resistors. Goes to show the Haltech runs some great output drivers.

Um, aren't the injectors on a GTR a negative trigger, so all the ecu has to do is earth them

That's the reason you remove the resistor, cause it's no longer needed and the high imp injectors will fry it

Sweet it should be better for e85 to a certain extent then as it doesn't need the efficiency that it would for 98

    • Yup. You can get creative and make a sort of "bracket" with cable ties. Put 2 around the sender with a third passing underneath them strapped down against the sender. Then that third one is able to be passed through some hole at right angles to the orientation of the sender. Or some variation on the theme. Yes.... ummm, with caveats? I mean, the sender is BSP and you would likely have AN stuff on the hose, so yes, there would be the adapter you mention. But the block end will either be 1/8 NPT if that thread is still OK in there, or you can drill and tap it out to 1/4 BSP or NPT and use appropriate adapter there. As it stands, your mention of 1/8 BSPT male seems... wrong for the 1/8 NPT female it has to go into. The hose will be better, because even with the bush, the mass of the sender will be "hanging" off a hard threaded connection and will add some stress/strain to that. It might fail in the future. The hose eliminates almost all such risk - but adds in several more threaded connections to leak from! It really should be tapered, but it looks very long in that photo with no taper visible. If you have it in hand you should be able to see if it tapered or not. There technically is no possibility of a mechanical seal with a parallel male in a parallel female, so it is hard to believe that it is parallel male, but weirder things have happened. Maybe it's meant to seat on some surface when screwed in on the original installation? Anyway, at that thread size, parallel in parallel, with tape and goop, will seal just fine.
    • How do you propose I cable tie this: To something securely? Is it really just a case of finding a couple of holes and ziptying it there so it never goes flying or starts dangling around, more or less? Then run a 1/8 BSP Female to [hose adapter of choice?/AN?] and then the opposing fitting at the bush-into-oil-block end? being the hose-into-realistically likely a 1/8 BSPT male) Is this going to provide any real benefit over using a stainless/steel 1/4 to 1/8 BSPT reducing bush? I am making the assumption the OEM sender is BSPT not BSPP/BSP
    • I fashioned a ramp out of a couple of pieces of 140x35 lumber, to get the bumper up slightly, and then one of these is what I use
    • I wouldn't worry about dissimilar metal corrosion, should you just buy/make a steel replacement. There will be thread tape and sealant compound between the metals. The few little spots where they touch each other will be deep inside the joint, unable to get wet. And the alloy block is much much larger than a small steel fitting, so there is plenty of "sacrificial" capacity there. Any bush you put in there will be dissimilar anyway. Either steel or brass. Maybe stainless. All of them are different to the other parts in the chain. But what I said above still applies.
    • You are all good then, I didn't realise the port was in a part you can (have!) remove. Just pull the broken part out, clean it and the threads should be fine. Yes, the whole point about remote mounting is it takes almost all of the vibration out via the flexible hose. You just need a convenient chassis point and a cable tie or 3.
