Gaz Walker Posted November 20, 2008 Share Posted November 20, 2008 From JCPN: It was only a matter of time before it happened, but it seems that an Australian workshop has managed to take the engine of their R35 GT-R right to the raggedy edge - and beyond. Yep, somebody's managed to destroy Godzilla's plasma-lined heart in the pursuit of ultimate power. The car, which was being used by ECU firm Haltech to conduct some fairly exhaustive R&D, suffered a catastrophic engine failure at Eastern Creek Raceway near Sydney at the end of last month, and it's only now that a complete teardown of the VR38DETT has revealed what went wrong deep inside the R35's engine bay. It appears that the culprits were the number 1 and number 3 pistons, which split horizontally at the wrist pin and sent the crown up into the valves and the skirt down into the depths of the crankcase. The number one and three conrods, no longer being confined by the pistons at the small end, then proceeded to smash their way through the remainder of the engine, destroying the block, oil pump, sump and the plasma-lined cylinder bores. Needless to say, Haltech's VR38 is now one hell of a paperweight. GT-R owners need not be worried just yet, as Haltech's spectacular engine failure doesn't necessarily mean there's anything inherently wrong with Nissan's new wunder-car. Haltech's GT-R was reportedly cranking out a massive 400kW at the wheels (543hp) when the engine, for want of a better phrase, shat itself That's a huge increase over stock, and big power by any measure. In fact, it's practically miraculous the standard cast pistons lasted that long in the first place, given the extreme testing Haltech inflicted upon them. The story doesn't end here though. Haltech are in the process of shipping over a brand-new block with Darton sleeves, while proper forged pistons and stronger conrods will also be specced for their new motor. Given all their previous experiments were run on a stock motor with stock ancillaries, it'll be interesting to see how much power they manage to extract with the stronger aftermarket goodies whirling away within the bowels of their GT-R. We wish them luck. Quote Link to comment Share on other sites More sharing options...

The Raven Posted November 20, 2008 Share Posted November 20, 2008 oh no , just got my exhaust today am a little worried You should be, the only way out i can see is that you give the car to me for safe keeping. Quote Link to comment Share on other sites More sharing options...
Gaz6002 Posted November 20, 2008 Share Posted November 20, 2008 oh no , just got my exhaust today am a little worried Are you going to up the boost at all mate? I wouldn't lol. Have you had it on rollers? Before and after the exhaust would be nice to see Quote Link to comment Share on other sites More sharing options...
Jurgen-Jm-Imports Posted November 20, 2008 Share Posted November 20, 2008 Its a $#@!ter (give ya £20K for it) ok done 5zigen exhaust sold on forum for 20k Quote Link to comment Share on other sites More sharing options...
Gaz Walker Posted November 20, 2008 Author Share Posted November 20, 2008 oh no , just got my exhaust today am a little worried LOL - don't be daft, these were running 543 @ the wheels so at least 600 at the flywheel! It'll be fine Gaz. Quote Link to comment Share on other sites More sharing options...

Before and after the exhaust would be nice to see 504 it made before fly figures and this is supposed to take it too 560-575 with a small boost increase.. what was haltechs gtr doing fly figures ? can anyone work it out Quote Link to comment Share on other sites More sharing options...
Gazboy Posted November 20, 2008 Share Posted November 20, 2008 Nissan are claiming really low friction losses on the GTR aren't they, I wonder what the fly hp was? I make it a shade under 600bhp. Did well really. Quote Link to comment Share on other sites More sharing options...
Jurgen-Jm-Imports Posted November 20, 2008 Share Posted November 20, 2008 LOL - don't be daft, these were running 543 @ the wheels so at least 650 at the flywheel! It'll be fine Gaz. 650bhp still sounds too low for engine to destroy it self Quote Link to comment Share on other sites More sharing options...

tooquicktostop Posted November 20, 2008 Share Posted November 20, 2008 I was expecting the stock engine to have a tolerance greater that that, but I guess if you go in search of power beyond the factory level you are taking the risk it goes bang Quote Link to comment Share on other sites More sharing options...

Gaz Walker Posted November 20, 2008 Author Share Posted November 20, 2008 650bhp still sounds too low for engine to destroy it self I was working it out at 15% but I think the GTR is more like 10-12% in RWD mode so maybe around 600hp. You've got to bear in mind this is a light alloy V6 not a cast iron straight 6 behemoth like the Supra! Gaz. Quote Link to comment Share on other sites More sharing options...

Swampy442 Posted November 20, 2008 Share Posted November 20, 2008 Bet Nissan are gonna be VERY interested in that engine. Had to happen I suppose Quote Link to comment Share on other sites More sharing options...
Digsy Posted November 20, 2008 Share Posted November 20, 2008 Bet Nissan are gonna be VERY interested in that engine. Had to happen I suppose I don't think they will be in the slightest bit interested. They'll have tested it to death for the performance levels they wanted to sell it at. End of. As already mentioned, the days of massive over engineering are long gone. Quote Link to comment Share on other sites More sharing options...

Design parts to be just strong enough, rather than the old method of using a slide rule, then adding a bit for luck. Quote Link to comment Share on other sites More sharing options...
Nic Posted November 21, 2008 Share Posted November 21, 2008 There are a lot of GTR's here now with the HKS GT570 kit fitted, which ups power to around 570fwhp. Quote Link to comment Share on other sites More sharing options...
