Went to see this liitle v8 engine yesterday, I have to say it was very impressive, a huge engineering std and was a quality build.
v8 2.4 litre 400 bhp 5 valves per cyclinder, arrow steel rods, wisco slipper pistons, built in dry sump, 74mm crank height
Weight 74 kgs, 16 injectors :bow:, pectal ecu, throttle by-wire if you want, traction control.
Cost was heavy but it had all the right bits.

PS A 500bhp supercharged version is on the cards

No doubt a motorbike engine type development.
Im sure its a nice peice, but rather pricey. Id rather buy a cheaper, slightly heavier lump, that can make more power and torque.
A chevy lump weights 220kg and produces 600bhp
This weights 74kgs and can go to 500 bhp with supercharger, it is also tiny and will fit much lighter cars ..
It is a bike engine development but now only the cylinder head is used the rest is bespoke. It is very nice.

Seen a similair engine about 18 months ago.
As good as it is why are they modifying bike engines? why dont they design there own using bike technology and improve on it. I know it takes something to put together a piece of kit like this but lets see someone build one out of all new parts and not nick the components out of someone elses engine.

I think in this case that is slightly harsh, this engine only uses the cylinder head casting everything is in the head is replaced.
Why replace a cylinder head when it is at the summit of its particular design.

What i meant to say was why cant an engine designer build these units from scratch as oppossed to taking other manufacturers designs? why cant they build there own engines with there own criteria of bore X stroke, there own port designs and combustion chambers?
I have yet to see someone design an engine with similar characteristics to this without using technology taken off the top of a sports bike.
These engines are the closest we will get to F1 technology without the cost, if some monkey can work for Suzuki/Honda/Yam/Kwaka and produce this sort of power in a small unit and yet make it affordable to the average sports bike rider, why cant they do this to the mainstream manufacturers and produce something special?
Just my 2p

It would seem stupid and costly to develop an entire engine, when you can design a short motor, perhaps using off the shelf rods and pistons, and off the shelf cylinder heads, that are tried and tested.
Just having to design a block and crank would reduce costs no end.
having to design the entire unit from scratch would cost a fortune.

How often does it need to be rebuilt?
I know one of the new lightweight/high revving V8's needed to be rebuilt or atleast 'refreshed' pretty often.
The engine in the Caterham has done 22k miles ....without a rebuild. Only got their word for it though .
The block was well though out with enlarged water jackets for cooling,

similar to the Cyclone (i think) bike based V8, only they are using much more stock components. i think they are going for around £14K. be nice to see a twin turboed version (blower will sap some torque from athe crank). i think cyclone where talking of 600bhp as the bottom ends are bulet proof! make a great engine foe a Westham and even with the blower it still wont be that high!
thanks Chris.
PS. imagin two Holeshot 1.3 turboed Busa engine straped tpgether! 700bhp and 440lbsft! now that would be VERY nice!

Some Monkey ? There is more development and technology in a modern sports bike engine than you obviously think ! They are little works of art, precious, wonderful and without comparison this side of F1.
Some monkey . . . so P&O have a couple of boats do they ?

thats already been done in that 4wd ultima with 2 holeshot busa engines making 900hp together!
Anybody seen it run yet ? Interested to see what 0-100-0 it can manage
