400 rwkw - wtf??

[FASTXR]

Seems like a mighty big number for something thats not super- or turbo-charged...

hahahaha T5 behind that......BANG.

Damn. he would have to have spent in excess of 25k on the motor to get that, and with the cam it must have i'd hate to see it sit in traffic.

Yep - 227rwkw to go for you Richard.

Sounds like pork pies to me...

What's the output of a V8 Supercar? It'd be about that wouldn't it? Maybe not. Maybe he means 400 rwhp (300rwkw).

The car does not have an RWC, but otherwise is a bargain for all the work done to it. It was $35k not too long ago.

... and me.. unless of course the thing redlines at 9000rpm :

Total and utter bollocks. :ymca:

Ambrose's V8 Supercar, according to the site, makes 473kW at the crank. So, figuring your average loss for a manual, it should have approx 388rwkW. For 400rwkW with a manual, it should have approximately 510kW at the engine.

Yep, pork pies in any language.....

In total agreeance Mr Sparkle..

[XRated]

But damn those flutes look tough.

It could quite easily be a mistake... perhaps its 400rwhp (299rwkW)?

Or maybe 400kW at the engine. That'd equate to something around the 320-330rwkW mark.

it doesnt go into too much detail about the motor, and i would have to say there is SFA chance it makes those numbers, but its possible IMHO.

V8 supercars have to be under 5 litres, and i believe they have limitations to what valves/cams etc they can use, and have a 7k cutout.

assuming its a stroker and has no such limitations its POSSIBLE it could make 400rwkw, but not bloody likely.

remember there was that 351 clevo (maybe stroked closer to 400ci though?) at summernats a few years ago that made somewhere over 700hp naturally aspirated.

actually, IIRC that motor cost about 100k to to build, so i cant imagine someone selling a car with a $100k motor in it for 25,000.

maybe its just very tough and runs a sh!tload of nitrous?

V8 Supercars are limited to 7500, cams and valves are free, and if you look at a set of Yates C3L heads that they use, they are just enormous, and as far as I have known, there is no head available in Windsor configuration that will flow anywhere near the out of the box numbers the Yates heads flow.

My cylender head guy is working with my AFR205's, and has seen the Yates heads, thinks I should buy them, because they are that much better.
I think Steffo is right, 400 at the motor, and its a misprint....

My mate's XD makes 665hp (496 kW) at the fly N/A with a 381 cubed clevo and its driveable on the street although with 4.5 gears economy is not exactly achievable. In full street trim it made 310 kW with wheel spin on the chassis dyno

[Steffo]

Brodix BF202 heads would maybe get close to the Yates setup. They flow 391cfm out of the box. The only Yates heads I've ever read up on were 368cfm. Not sure if they were C3L or not though.
