Looked like the last part of the clip was filmed in 3rd?

A loose water line won't cook it, thats more of an additional safety thing - so long as it had a good oil feed/drain it should have been fine. Either way, a GT3076R will crack 400hp @ wheels fine... if you are struggling to with a 56-trim full GT3076R then its the engine moreso than the turbo which isn't flowing enough.

I thought he hadn't decided yet?

Would be good to see some actual dyno figures for a Holset on an RB, as much fun as it all sounds any semi-decent reasonable sized turbo makes for a fun drive on an RB25

I never noticed that, thanks Yeah am aware of those, a mate of mine has something along the same lines (an FP GT3586HTA) on his EVO but didn't really justify the extra lag over a GT3582R. I think if I were going to go up from a GT35R, I'd start looking at the GT40 series turbos which is essentially what the guy with the EVO is going to do - either return to a GT3582R or shift to a GT40xxR.

Ahh ok On my wish list is a twin scroll 1.06a/r T4 for if I keep going with mine.... one of those would be intensely cool I reckon!

Is it a twin or single entry T4? And if its twin, is the manifold a split pulse one?

Scarily enough, there are people now claiming up around 900hp on T3 hotsides these days!! 8.75 @ 162mph on E85 with a T3 flanged turbo in a 4door car running interior/glass etc is a bit mad and not something I've have ever expected to see without NOS:

Yeah cheers for sharing, its a really nice example of a GT3582R setup - should be good to hear how it goes at the track, please share your impressions when you get a good chance to try it out

You said it again - where did you get the idea that the GT3582R is rated at 750hp? http://www.turbobygarrett.com/turbobygarre...2R_714568_2.htm

Yeah as much as I am pro-single turbo, this comparison is like the other side of the typical twins vs single comparisons where people would get a T88 RB26 and run it on an engine set up to run twin GT2530s and say "Look, they made similar power but the GT2530s spooled way better! Twins ftw!". A paid of GT2835s are quite a bit more serious than a single GT35R, though having said that the lag seems quite substantial for a GT35R and he says its rated to 750hp?! Is it definitely a GT3582R? Good power, either way

Yeah its hard to say at this stage, he might just be pushing all the thing is keen to all around. I have seen higher numbers from them, but from more aggressive engine/boost/fuel setups and its hard to tell how dynos compare. 363rwkw on a Mainline is fair roaring it out, I'd expect this thing to be one of the more brutal "all around" RB25 setups anywhere.

I thought they leaned towards IHI turbos? If I had more money than i needed, I'd be very keen to play with a PE RX6-R...

Awesome work man - I am well stoked you pushed it that hard and got the results I hope they bring that fuel out here... Who would have thought? http://www.skylinesaustralia.com/forums/in...t&p=4336498

Haha glad you appreciated it Can't take these threads too seriously, but it is interesting to try and get to the bottom of it - I struggle to see in most cases what HKS could do to make something that is made up of essentially the same parts could be wildly different. If I were more bored (could happen still) I'll go through the RB26 dyno results to see for myself, isolate a few variables such as boost level and modification level to see if I can get a control boost/mod level - if I do, I'll post the results regardless of whose favour (if any) it swings in. I don't have a blind preference, though make no secret that I find it hard to believe that two turbos with the same part numbers would somehow be completely different... however if it turns out to be true it'll be very useful to know. It does seem weird that the GT2860-5s have an average power of just over 300kw @ wheels when its well known and proven they can go well over that power level without much trouble at all - kindof makes it seem that there are probably a few cars (if the sample is small enough it'd only need one) which are no way near leaning on the flow levels to drag the results right down, or one making a huge power level on the 2530s to drag the average up.

Problem is different dynos, different amounts of modifications and boost etc for different setups make it harder to compare apples with apples. People who have paid for the more expensive items usually would have more to spend on getting EVERYTHING up to spec and as such squeezing the best out of them. This is an interesting entry in a NZ tuners blog: http://sthitec.blogspot.com/2009/06/gtr-week.html

I might be out of date, but didn't the Hi-Octane guys take your "low mount record" with a pair of lower specced generic Garretts?

I'm running a Garrett GT3076R on it so you can't run a stock dump pipe on it, I have front pipe as well. Is an awesome sounding exhaust with the bigger turbo as well

Pretty sure the Oz publications did a turbo shootout with a bunch of twins where if I remember rightly the T517Zs provided the best all around performance? They certainly seem to be the goods.

Wow thats interesting, the spool is no better (if not a little worse) than my full GT3076R running a .82a/r turbine housing!!

14.0 @ 98mph?

Depends on the turbo setup, the car etc etc. If you are getting soaring exhaust manifold pressure then you are quite likely to get a good gain - if its all relatively under control then may not be worthwhile. If you are running a .68 housing on a GT30 and making 320wkw then I'd guess you're probably pushing it quite hard, and the .87 may free it up a bit though its really just a semi educated guess.

That looks and sounds awesome, nice work - look forward to hearing how it goes. Its an RB30 bottom end, eh?

Link make the ECU which calls the shots on the fastest RB30 powered car in the world (may be the quickest RB in this part of the world not running meth too?).

Exactly Different wheels/housings etc can relate differently. A .64a/r GT25R isn't likely to touch 200kw @ wheels, a .63a/r GT35R will crack 350kw. He actually hit 340kw, his 370kw @ wheels was speculative and I pretty much wrote that off... if he bumped the boost up he might discover hints that it wasn't going to go much higher anyway Not sure which cars you are talking about. I know mine has done low trap speeds for the power it has, but that has been more to do with me never being able to get at the power I was making on the dyno due to fun things like ignition misfires and boost leaks Ditto the other side, I am actually leaning more towards somewhere in the middle. There are plenty of people out there who have made ridiculous power (and the times to suit) on .63a/r T3/T4s for years - in our part of the world it seems they haven't been looked into or as understood as elsewhere but it doesn't mean it can't be done. I'm just saying don't bag a setup you aren't familiar with too quickly. Pretty sure the fastest pump gas EVO in the world (traps near 150mph) runs a .82a/r T3/T4 I made an estimate on what trap speed I'd hope from a Skyline making xxx.kw on a Dynapack dyno as I am more than familiar with them, much as you guys are familiar with Dyno Dynamics. I know that an R33 making ~370kw @ hubs set up "normal" should run 127-130mph or a few less with 340kw, to put it more into perspective.
