If 700BHP is unusable on roads then how does Andy get anywhere in his car?

Is a 450BHP Evo Faster than a 700BHP Scoob?

The drive shafts will be on the limit, especially if you are using really sticky tyres on large rims.

I'm running on the 500 mark and must admit I'd be dubious of adding more on UK 6 speed...heard they'll do 600 bhp maybe but I've already had syncro problems.

You're really looking at a custom build everything motor for a "reliable" 700bhp daily motor.

I'm about to uprate my engine and gearbox mounts again as they dont like 500 ft/lb torque....you'll need mounts made from rock to hold everything in line with that power figure...

Didn't RCM have a 700+ scoob? Is that one reliable?

At 700bhp are the PPG rated at that much? I know Steven Darley has been breaking them at around 550bhp IIRC, but he does seem to be more brutal than others with the transmission

aren't both Mark (lateral) and Paul (Zen) both running more than Steven on PPG sets?

Yes IIRC they are running more but does not change the fact Steven has had gearbox failures at lower power levels. Having said that I could be wrong, I think there is also PAR? It maybe that gearbox Steven has had problems with.

Someone else can maybe confirm which Gearbox/Gearset Steven has been running?

thanks for the replys guys...

the car will do the odd track day but mostly its a road car with NO full bore launches so it might last a while on standard stuff.

Just looking to see whats avail for when it does break.

As if we believe 'NO full bore launches'
Surely nobody can resist the temptation?

I find it hard to believe that anyone would want a 700bhp scooby for the road. 450/450 ish is surely the useable limit. Anything above that gets really really expensive and stops the car from being 'just driveable' IMO.

Albeit they are road useable:
I am sure AndyF doesnt just nip down the shops in his, he would take the Spec C.
I am sure Zen dont drive everywhere in the Zen Impreza, they take the 4WD (or whatever it is - sorry Paul/Liz)
and I am sure that the Gobstopper gets partially stripped between events and wrapped in cotton wool rather than parked down the local Asda.

and you're right Graham - full bore launch has to be tried once

I have to agree, mine at 500 mark is just not an every day car...the petrol (plus the fuel additive at each fill up) plus £150 tyres (each), plus the water tanks etc, takes longer to get my car out of the garage than the journey - although it is fun making up lost time

I have a little eco car to try and prevent fuel pumps in the UK going dry...

We run a stock (JDM) 6 speed at ~700bhp.

We have also been to Sainsburys in it too

no such thing as bullet proof at that level

I wouldn't expect my PPG to hold up under that power
