Sometimes mate, when you have to sell impractical things it just has to be done.
We all know there is a emenently practical (and superior in all ways) vxr8 out there with your name on it!

Rich is right. Just be sure there are no holes in the boot. Oh and if you want a really quick car get a Monaro

It`s sooo lardy they dropped the gear ratios (and fuel economy) just to keep up with the `ro`.

Mind you with 2 limiters fitted top speed isn`t an issue

Well I only saw one street tyred Monaro beat me at the track and that was by less than a tenth of a second. Plus it blew up not long after!
It seems you need a second mortgage to beat a vxr8 around here and multiple approaches to power smile

And I agree the extra 200kg doesnt help. Makes you wonder if that 10th of a second really made up for the 200kg weight difference...

Should be an interesting dyno day.

Erm.....its not all cams and heads with your really is it?

You have got a slightly cheaty 7 Litre engine too

No doubt your car is quicker than a stabbed rat over the quarter though bow

Ah, but its not all about the displacement.
I only had 20% extra displacement.
Roger had 80% extra air density over standard.

Where did the extra 60% air mass go? It went into supercharger waste world!

Im guessing your beasite will reduce that 60% waste substantially. But Im sure we can do some calculations with your displacement and boost and compare the relative efficiencies of each engine in making BHP. Ill let you generate more Gross horsepower however I suspect you will burn substantially more lb of fuel per rwhp biggrin

I suspect you wont want to compare rwhp per £ spent either wink

Ahhhh yes, the old General Custer syndrome.

Even if your troops are well trained and efficient.........

You`ll still get your ass handed to you if there`s enough bare assed Indians hehe

No, the rules of diminishing returns really do apply to horsepower (Now if we were to compare with S800`s I`m sure the scales would fall the FI way though )

Ok get S800 to bring his current engine to the dyno, if he can find all the pieces. I think Ill still win as even 50p divided by zero is zero smile

Get him to add his working engine on top and we will still have a good game on!

I agree with the indian's btw. I can see them circling!

Rich... remember Jezz has more or less everything you have plus two dirty great turbo's.... best of all worlds Id say, silent, very fast and no drag on the crank from a charger pully. smile

Yeah, its not not as efficient as NA though smile
I expect nothing less than a total thrashing given the setup.

I need go no further. Mine is already faster than a Dodge Viper and an Audi R8.

However Ill still identify inefficiencies where they exist, you can rely on me for that biggrin

Jez has simply moved the load off the crank and used it to block off the exhaust flow. Sure its more efficient than a PD blower, but then so is Gordon Brown.

That's one way to look at it. Another is to say you'd need a 9 litre NA engine to produce the same power as a 6.3 litre with FI.

Lots of manufacturers including BMW are moving away from NA in favour of more fuel efficient turbo engines with lower emissions. Take the new M5 for example.

Yeah, good point.
All the manufacturers are embracing FI now.
