Haltech Finds The Limit Of Their R35's Engine

As many of you may be aware the Haltech R35 GTR Skyline had a catastrophic blow up on Friday the 24th if October. Our GTR has been running on a new platform of Haltech engine management flawlessly for over 5000km's now.

The car was being track tested at Eastern Creek raceway

(http://www.eastern-creek-raceway.com/) when the engine let go. The car had completed countless flat out laps with the engine producing 400kw at the wheels, up from 300kw at the wheels - The driver tells me it was a terrific ride!

After finishing Haltech's latest Flat shifting calibrations a few more test laps had to be carried out. With no sign of trouble the car went out and successfully completed 2 more laps before finishing up on the side of the track leaving a trail of oil and plume of smoke behind it.

It was time to put it in the trailer and go back to the workshop to pull it down. After building up enough courage our in-house mechanic removed the VR38DETT from the car and set it up on the engine stand.

A few hours later the engine was fully stripped and the damage to the engine was clear - It appears Haltech have found the limits of Nissans new super car!

The engine had met its maker.

Piston #1 and #3 had separated from their lower halves right through the center of the gudgeon pin. As the Conrod's had no piston's to guide them up and down the bore they started smashing the bore, block, oil pump, sump and anything else that got in their way.

Due to the massive damage to the block we will need to replace it. And figure it's a great time to make the engine a little stronger. We will be boring the motor out and installing Darton sleeves, replacing the factory cast pistons with a study Forged unit as well as installing a set of Billet conrods. This should allow the engine to reliably produce over 400Kw at the wheels and handle the pressure.

Keep an eye on the Haltech website or drop us an email anytime for further updates.

this is how the R&D works.

Drive it and upgrade it slowly until it let's go.

Once it lets go, research the causes and weaknesses, and built a package that will ultimately make the identified sections stronger, and allow much more power and upgrades to occur.

Once you have this package in, tested and showing potential you start selling the package, and perform the original process all over again.

As you get more and more performance mods, you add to stage 1's package until the engine blows up again.

Now you have the upper limit of stage 1, and the supporting aftermarket mods for it.

Once you rebuild the second motor, you have the base line for stage 2 under way, and you keep upgrading until you blow the motor again, and you again have the stage 2 kit, the supporting mods, and the upper limit all sussed out.

drop us all a line when you get a price on the block and other parts from nissan :D

will be interesting in the coming months whats going to happen to alot of the other cars that are pushing numbers.

good luck with it anyway and also glad to see Aussies leading the way with this kind of stuff!

Blowing cars up? :D

Just kidding. 400AWkW is quite astounding if the only thing changed was the ECU. So does that mean the car could have reliable and comfortably ran 350AWkW by changing just teh ecu without many dramas?

I have been waiting for this also. Will be interesting to see if other failures result from the same thing.

Also interested to see how much all new gear will cost to strengthen it for the next round of abuse

Hmm should chuck a 2J in there, 400rwkw on stock internals wouldn't be a problem then :P

j/k

like someone said, good time for some R&D and gives them a chance for a good footing in the modification of R35s.

      Blue slip

      I mean, I got two VASS engineers to refuse to cert my own coilovers stating those very laws. Appendix B makes it pretty clear what it considers 'Variable Suspension' to be. In my lived experience they can't certify something that isn't actually in the list as something that requires certification. In the VASS engineering checklist they have to complete (LS3/NCOP11) and sign on there is nothing there. All the references inside NCOP11 state that if it's variable by the driver that height needs to maintain 100mm while the car is in motion. It states the car is lowered lowering blocks and other types of things are acceptable. Dialling out a shock is about as 'user adjustable' as changing any other suspension component lol. I wanted to have it signed off to dissuade HWP and RWC testers to state the suspension is legal to avoid having this discussion with them. The real problem is that Police and RWC/Pink/Blue slip people will say it needs engineering, and the engineers will state it doesn't need engineering. It is hugely irritating when aforementioned people get all "i know the rules mate feck off" when they don't, and the actual engineers are pleasant as all hell and do know the rules. Cars failing RWC for things that aren't listed in the RWC requirements is another thing here entirely!

      Best place to order Authetic R32 Parts in Japan

      By GTSBoy · Posted

      I don't. I mean, mine's not a GTR, but it is a 32 with a lot of GTR stuff on it. But regardless, I typically buy from local suppliers. Getting stuff from Japan is seldom worth the pain. Buying from RHDJapan usually ends up in the final total of your basket being about double what you thought it would be, after all the bullshit fees and such are added on.

      Ethanol Content Sensor - Always at 11%?

      By GTSBoy · Posted

      The hydrocarbon component of E10 can be shittier, and is in fact, shittier, than that used in normal 91RON fuel. That's because the octane boost provided by the ethanol allows them to use stuff that doesn't make the grade without the help. The 1c/L saving typically available on E10 is going to be massively overridden by the increased consumption caused by the ethanol and the crappier HC (ie the HCs will be less dense, meaning that there will definitely be less energy per unit volume than for more dense HCs). That is one of the reasons why P98 will return better fuel consumption than 91 does, even with the ignition timing completely fixed. There is more energy per unit volume because the HCs used in 98 are higher density than in the lawnmower fuel.

      No, I'd suggest that that is the checklist for pneumatic/hydraulic adjustable systems. I would say, based on my years of reading and complying with Australian Standards and similar regulations, that the narrow interpretation of Clause 3.2 b would be the preferred/expected/intended one, by the author, and those using the standard. Wishful thinking need not apply.

      Yes they do. For some maybe. But for those used the most by abusers, ie Skylines, the numbers are known. The stock eyebrow height for R32/3 Skylines is about 365/375mm or thereabouts. The minimum such heights are recorded in adjacent columns in the database.
