Hey guys I was wondering what's the record at the drags for the fastest low mounted turbo GTR in tas

Also what's the record for the most horsepower/killawasps out of a low mounted GTR?

I was on google trying to find some answers with no luck. Hope you guys can help me out. Cheers

I remember seeing it at the drags a couple or so more years ago, sweet car! did it get a 9 second pass down tas or just in the mainland, I seen on the ignigtion video that it made 502awkw is that the record for power? It's all I could find

In TAS its XRATED with a 10.2, twin low mount.

You most likely wont get the chance to beat that either as it is only 1/8th now.

He 'only' had 400kw, that was around 2008 from memory.

AUS wide, the drag time, I think it's still the HI Octane R32 GTR. with around 9.7
GAV from WA made 530?kw with twin GTX2863's lowmounted

2006... looong time ago. ha ha ha.

were the gtx2863's direct replacment low mounts? eg can mount on stock manifolds etc?

Low's the street beast comming along mr Jangles? Didn't you buy a stagea to? Man we're going to have to get garages side by side at Powercruise!

The GTX series bolt up using standard -5,-10,2530,GTRS rear housing, the intake has to be custom fabricated as it is 3" & 2".... Some crowds are machining them into the standard compressor housings now, not as good performance wise as full gtx trim from reports, but gives full standard look/bolt up.

Nah I don't have a stagea, but I do have a garage

Is there anyway of finding out the records for the drag classes. Now I no that they won't have the recored I'm after but it would be worth a read to see what has been done there.

Also XRATED what kind of tyres did you use? Semi slicks, street tyres or drag slicks?

The car was raced as a true street car and on street legal tires, full exhaust etc (just like you would drive it every day).

As far as I'm aware, there was never any class/record for 'low mount, GTR skylines'... it's really just an enthusiasts recognition. The car was the first GTR in Tassie to break into the 10's, at the time it took home quickest AWD, fastest import and a few other local awards that were done through TDRA.

As far as I'm aware it's still one of the fastest 'original factory engine' eg unopened GTR passes made in Aus?

I'm still surprised there is still interest in it as most people choose to use they're skylines for different racing disciplines.

Cheers

Jangles are the gtx 2863's Internally gated?

The GTX2860, 2863 and 2867 use the same turbine as gt2860 -5 and -10. Also hks 2530 and GTRS.

Therefore they bolt straight into the turbine housing. You can use other housings of course, but this allows for stock low mount manifolds to be used..albeit with custom inlet piping.

So yes, internally gated in standard low mount gtr position.

I had a set of gtx2860's on a 2.6, with modified manfolds for external gates. but that plan changed.

On a setup like yours I'd be dropping in smaller duration camshafts and buying my gtx2860 setup ;)

Tyre frying boost from 3500rpm, and 500kw on e85 30psi ( not tested, just theory )

    • For once a good news  It needed to be adjusted by that one nut and it is ok  At least something was easy But thank you very much for help. But a small issue is now(gearbox) that when the car is stationary you can hear "clinking" from gearbox so some of the bearing is 100% not that happy... It goes away once you push clutch so it is 100% gearbox. Just if you know...what that bearing could be? It sounding like "spun bearing" but it is louder.
    • Yeah, that's fine**. But the numbers you came up with are just wrong. Try it for yourself. Put in any voltage from the possible range and see what result you get. You get nonsense. ** When I say "fine", I mean, it's still shit. The very simple linear formula (slope & intercept) is shit for a sensor with a non-linear response. This is the curve, from your data above. Look at the CURVE! It's only really linear between about 30 and 90 °C. And if you used only that range to define a curve, it would be great. But you would go more and more wrong as you went to higher temps. And that is why the slope & intercept found when you use 50 and 150 as the end points is so bad halfway between those points. The real curve is a long way below the linear curve which just zips straight between the end points, like this one. You could probably use the same slope and a lower intercept, to move that straight line down, and spread the error out. But you would 5-10°C off in a lot of places. You'd need to say what temperature range you really wanted to be most right - say, 100 to 130, and plop the line closest to teh real curve in that region, which would make it quite wrong down at the lower temperatures. Let me just say that HPTuners are not being realistic in only allowing for a simple linear curve. 
    • I feel I should re-iterate. The above picture is the only option available in the software and the blurb from HP Tuners I quoted earlier is the only way to add data to it and that's the description they offer as to how to figure it out. The only fields available is the blank box after (Input/ ) and the box right before = Output. Those are the only numbers that can be entered.
    • No, your formula is arse backwards. Mine is totally different to yours, and is the one I said was bang on at 50 and 150. I'll put your data into Excel (actually it already is, chart it and fit a linear fit to it, aiming to make it evenly wrong across the whole span. But not now. Other things to do first.
    • God damnit. The only option I actually have in the software is the one that is screenshotted. I am glad that I at least got it right... for those two points. Would it actually change anything if I chose/used 80C and 120C as the two points instead? My brain wants to imagine the formula put into HPtuners would be the same equation, otherwise none of this makes sense to me, unless: 1) The formula you put into VCM Scanner/HPTuners is always linear 2) The two points/input pairs are only arbitrary to choose (as the documentation implies) IF the actual scaling of the sensor is linear. then 3) If the scaling is not linear, the two points you choose matter a great deal, because the formula will draw a line between those two points only.
