RAOC Proving Day 2 - Confirmed 30/11/07

330bhp was the max ever acheived on the PRV, but this is on race fuel, 8000rpm, sliding throttlebodies, 300+ degree cams with completely reworked heads, valves, ports etc.

Er *cough* - 600bhp on a stroked 93mm 12v at 2 bar boost by Kevin Jones. And the engine is still going.

800bhp from a bespoke-head twin cam odd-fire by the Pug WM LeMans team.

Ref the "smaller wheels" argument. You haven't given me any physics, only "if it were that easy, everyone would do it". I'm sure the gear ratios on top fuel dragsters are optimised so that they can use the traction offered by big wheels.

Are you telling me two identical PRV powered cars will do the same 1/4 mile times if they have a different final drive? And if so, explain to me how?

Does anyone have performance info and tech spec from the Europa cup GTA ???

Martin, *cough* we were talking normally aspirated......



As for the PUG LM, well you just said it, custom twin cam 24v heads. Its no longer a PRV apart from the fact its the original block. All the bad bits of the PRV design have just been replaced!

And even then, 800bhp for 4 bar boost on race fuel isnt really that good...

Martin, don't ask me to write it down, Im not Newton, but in simple terms the one with short gearing will get to say 30mph in top of first for instance, in a shorter time than the longer gear will hit 40 in the top of first, but the difference is it will have also travelled less DISTANCE down the track, whereas the longer gear takes longer to get to the higher speed, but travels further doing so.

Acceration is all about getting to a speed quicker, but you are not actually travelling as far doing so, and this is the thing with drag racing, it it distance related to time, not just time..

If you do a search on the net, you will find a myriad of ET, 1/4 mile calculators etc which are very accurate (this is the same type of system the Racelogic box uses) and not once will it ask what gearing or tyre size is required for the time crossing the line, other than telling you what speed you will be crossing at.

Likewise, as I kept on saying, people would put the shortest gearing and small wheels on their drag cars before anything else if it was so, but they don't.

?

Still going... Its gone so far no one has seen it since..

Martin, don't post things like this until it can be shown/proved, otherwise I can say my Aunt Mable has a 601bhp PRV.

Not that 601bhp is unacheivable in anyway, its just she hasnt done it.

Does anyone have performance info and tech spec from the Europa cup GTA ???

260-280bhp - boost 1.5-2bar. Standard remapped ecu, higher fuel pressure, no ISCV, bigger intercooler, same turbo as my stage 2, bigger rad etc...

All mixed figures though. Theyve quoted 180mph which isnt possible with that power.

Gawd you two don't half talk an incredible amount of bullocks


I'm still waiting for either of you to turn up at an event in your own car ! let alone one you've had a hand in building /tuning
.

Feck building them, far cheaper just to talk about them all day long and in dreamland they go twice as fast..

Im sure I told you I was going to come to Brunters in my Clio with the V6 Turbo engine the back...but decided not to..

Can i just butt in and ask why you decided not to?

Cos it was easier to ship the engine to Lee on a pallet, that scratch up my tailgate...

or too much competition?

Dropped Hidden and Lost Well it aint here yet

Keith

You missed my post above

As for cars, im not a competative person when it comes to power/speed, because I know damn full well, no matter how fast I make it, there is always going to be someone faster, so why bother. Just make the car for yourself and what you want out of it. Im quite happy in a non turbo standard 2.8 GTA for my own car compared to most.

Don't ask , the bitched because my old unit was in a 7 tonne weight restriction, and they had a 14 tonne lorry..

or too much competition?

Your car is disqualified anyway ................You had a ringer driving it
