Quad Turbo VH

[maxnix]

If only we had this much room under the hood and Race gas all the time.

















The detail work he exhibits for the breathing of the engine is exquisite.

We need to get Simon to post more frequently here and maybe produce some street goodies for the VH here in the states. Not much market down under, I am afraid.

Is that Nizpro as in Simon Gishus?

I never realised they did an VH stuff. All of their work is epic.

They did the VH45 twin turbo in that race boat.This one is a VK by the looks of it

[maxnix]

Yes, I believe this is a development of the original VH45DETT they did.

I think it shows abundantly well how good flowing the heads are and how little shrouding from the valves. I certain is is a bore and stroke to get to 6L.

I'm pretty sure that's actually a VK56 (it may be a VK45, but I wouldn't think so). The front timing cover gives it away, its a VK front timing cover, not a VH.

Still very awesome regardless.

[maxnix]

You know, you might be correct. The camshaft looks like they have the narrower included angle of the VK. An even more impressive acheivement in my book. The oil filter mount might be a give away also. Wich I could see the lower left side better.

I did some digging and found more pics here

Hi all,

Feel free to jump on the forum and ask Simon any questions you have. He will be more than happy to chat.

Cheers.

Phenomenally gorgeous... I love to see fabrication on that level. Top-notch attention to detail!

Now, I can see that bolted into the front of an old-T-bucket.... Hmmmm....

Man, in a second if he would guide us on a VH45DE build in a G50, which are very rare in Australia!

I am with AZHitman, that engine behind a Caterpillar radiator and a T bucket with a B&S 3.5 HP driving the water pump! Two kegs for gas!

Hello guys,

I was just informed that you had tripped over our ski race engine and wanted some info on it.

It does start life as a VK engine. We have successfully campaigned a VH45 DETT in Australia ski racing, including a trip to the world ski racing champion ships last year in New Zealand. The 4.5 engine develops 1177 hp and we get a service life of around 50 hours per engine. We run 22 psi of boost pressure and run it to 8300 rpm. Boat speed ends up at 126 mph. It’s in a 21 foot Force hull and run by the owner Ian Kilpatrick. You can see a down load of the boat footage on our web site.

http://www.nizpro.com.au/videos.html

It has achieved many Australian and state championships in the 8.0 litre class, over the last coupe of years. Mechanically it has 100% finish rate.

However we have always been a little low in the outright horse power stakes when competing against the 9.0 litre twin turbo Chevy’s. We have normally been able to run in the top 5 outright using the 4.5 VH.

During this time I have been developing this 6.0 version with the intension of running outright speeds. It is the acceleration from corner that’s hurts us compared to the big capacity engines not the outright speed.

Starting with the VK block and cylinder heads most other component are new. The intake manifold is a combination of magnesium intake runners CNC billet alloy valley plate and carbon fibre intake plenums. The plenums weighs in at 700 grams or 1.5 pounds each keeping the centre of gravity low. The rocker covers are also mag with carbo coil cover for a similar reason.

Internally it has the best parts money can buy billet crank, Ti rods and valves and the rest of the normal high quality parts you find in this style of engine. We have also cast a magnesium sump of 12 litres and it holds the internal oil cooler

The reason for the quad turbo set up is so there was no need to run a gearbox, ever the 9.0 TT boats runs auto gearboxes and use low gear to get out of the water with skiers. Our 4.5 VH didn’t even need this.

However I always say if it’s worth doing bludgeon it to death with over kill.

The turbo’s are stage similar to BMW’s twin turbo 3.0 litre diesels. The small turbos carry the engine to around 600 hp at any engine speeds, where the large unit takes over. The advantage is the large turbo’s can be very large giving very easy top end. With peak boost arriving at 1900 rpm on the little turbo’s and 800 ft lbs and the big turbos running 20 psi and 1500 hp on Australian 98 octane fuel, it makes light work of it.

I am unable to say how much power it would make as our engine dyno will not hold power levels above this. I would believe that 2200 to 2300 hp would be achieved especially if the duty cycles were lower than we see in ski racing.

Intercooling is taken care of from two large water to air intercooler built into the hull charge temps are around 5 degs C above river water.

All up including the forward/reverse gearbox the engine package weighs in at 320 kilograms 704 pounds maximum engine rpm is limited to 8500. The engine management system is Visteon using twin drive by wire throttles, coil on plug and electronic boost control.

Hope this is the info you were after.

Cheers Simon.

Thanks for the info Simon. Out of my price range but I love seeing the research others have done with the VHs and VKs.

Did your VH engine have similar internals (new crank, ti rods) to what you're running in the VK? Any reason why it was better to start with a VK block versus getting the VH block sleeved for more displacement?

[DeXteR]

WOW!!

Amazing piece of machinery right there.

[Mettler]

It's awesome to get a visit from someone with such intimate technical knowledge, and who has taken these engines so far.

Thanks Simon! Look forward to seeing you pop in more often. We want Nizpro aftermarket bits for our VH powered cars!
