VACmotorsport m62 engine 600HP? Are you kidding?

[dovlet]

I cannot imagine even how they abtain this power. Any idea?

It's a race engine, they exceed 100hp/L N/A quite often. This engine would be completely unstreetable.

My guess on the mod list would be:
Very aggressive cams
Solid lifters/heavy springs
Heavy intake, exhaust porting
Slightly larger valves
Headers
It obviously has ITBs
Incredibly high rev limit (which is where it makes the power)
High compression Pistons
Needs to run on +100 octane
Possible stroked to 4.6 or 4.8

That's all pretty standard stuff for NA circuit motors. The important thing to remember with this, is that the motor probably makes low 300s ft lbs of torque, being non vanos and having cams for peak HP, and that it makes 600 horsepower most likely around +8500 RPM.

Yep, that was my thought. It's a race motor built to run on racing fuel. While it is cool to see that kind of power from an M62, a race motor isn't really practical for daily driving. Look at the E60 M5 with its F1 inspired engine, that thing is a maintenance nightmare because of how high it revs.

I bet this sounds insane. Just like that v10 m5. When buying an engine like this I am sure money is no object.... Would love to see this in an e46 m3 or small chassis.

Muh M3 GTR clone

must add straight cut gears

I would just love to hear that motor scream by at 8000+ rpm.

Hi,

Just realized I totally mis-read the title and it's the M62 engine ! I totally read it as the 'S62' and hence posting up about the Ascari.



Apologies !

Cheers, Dennis!

Remember they also built (several times) Simeon's Baby motor - Once before and once after the One Lap back when..

Interesting fabrication of the cooling system.

[TxDarth]

You mean the intercooler for the SC? The radiator was stock, I believe it is now Zion tho...

[auaq]

Look at the reservoir that looks like is attached to the s/c bracket.

Cool E38!

From the looks of it, it has a dry sump, probably won't be using the BMW DME either.

It's the same engineering that brought Ferrari a 3.0L NA V12 producing +700hp in mid 2000s formula 1, just to a much lesser degree.i don't have torque figures on these engines, but I'm sure it's very low

Thanks to everybody for inputs, now it is little bit clear. Also, I read on their web that some one bought it in USA and managed to achieve 1000 WHP. If so, what is the torque? As we know the main thing is torque to run fast. Any Idea Gents?

~1200 bhp on an M62? Do you have a link? That's well into HP/L range of multi million dollar racing teams running cars that rev up to 18k. The re-engineering of an M62 at that point would probably cost much more than a purpose built engine. It would have to be severely destroked to even near that point NA, and the rest of the m62 doesn't not lend itself to high revs. While it is a relatively high revving engine for a production V8, the stroke is way to long (compare it to a Ferrari bore to stroke ratio), I can't imagine even the strongest forged connecting rods would last past 10k. Then you need to destroke. Short strokes do not mix air and fuel as well as long ones, and obviously you are losing displacement, so you need higher revs again to make up for it. At this point you will need custom heads because ported M62 heads won't have near enough flow. This is in addition to an already completely custom valve train, no aftermarket options will get you past 9-10k. Essentially, the only part of the engine you have left is the block.

The point being the limit of a NA M62 with already extreme modifications is around 650-700hp, I think I will be backed up on that

Also, torque is most important from a standing start, when racing circuit tracks where the car is always in the 6k-9k range, that's where horsepower matters (and this doesn't mean peak at the limiter, it means an smooth curve in that range)

Surely it has to be a turbocharged engine to make that amount of power. Pretty sure the cylinders were bored and then sleeved to handle a lot of boost.

Yeah. They've had that ITB M62 on display forever. If/when it was ever in a car for sure it has always appeard to me that it was only for a short time just to 'prove it could be done'... and all the other comments are spot on - it'd have been a total stand alone custom race motor. There's not much about that that would be BMW M62 in the end except the block and the heads. I've seen that motor in person on the stand at their shop and honestly it looks more like a bling bling display proof of concept than it does a real motor.

Looks like, but if you will research their website they says that they have also results that it is giving more than 1000WHP on dyno with Supercharger 6psi. So, that means someone already bought it & tried, if they not lying us. Any way there is no many info regarding to this engine. Also price is not shown, may be that never been sold and no body tried that engine. And that is only on their words that it is able to produce 600HP. I am sure if some one will call them to ask price for that engine they will say about very expensive price (no concurrent cost in comparing with alternative engines) that no body could buy it.
