Haltech Finds The Limit Of Their R35's Engine

[PJ.]

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.

eehehehehe I was waiting for this thread

Kind of a shame to see it let go, but at least we're finally starting to learn it's limits!

who woulda thunk it even had any

[2BNVS]

good to see that the limits have been found, makes for better/reliable future modification

[turbo_brian]

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.

Any other reported deaths?

One death hardly means the limit is found, could be due to a multitude of things and factors.

[Angus Smart]

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

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?

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?

[The Bogan]

I would have thought that it would have forgies as standard ?

Sit nissan, Bad dog...

[babyskyline]

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

[PM-R33]

Is this the first one to let go in the world to your knowledge?

i too have been waiting for this,.. was also waiting for pics

[heslo]

Damn, such a shame but we are lucky to have those brave few testing the limits for us so we don't have to!

Best of luck with the new motor!

[Beelzebub89]

Dam thats a shame. Any pics of the carnage?

Not at this stage

[RB30-POWER]

400rwkw at all 4?

[AndrewJZX100]

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

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.
