I'd say the guy I have used would charge about 10k for a proper 500hp engine.
I know he is a firm believer in the oldschool setups that are proven to work.
Most people who have that power cannot drive a 300hp car round a track fast so having 500hp A: sounds good and B: makes them look fast when the truth is as Greg Rose seems to show anytime he goes on track in the Martin Johnsons (sp) RS500 is that a well setup oldschool engine/car can roast most things in the right hands.

no matter if you spend 4k or 10k on a T4 motor if you can't drive the fooking thing properley your throwing good money in the bin imo or your just chasing figures for pub talk

The problem is simply getting carried away with turbo this and that, a stage 3 engine or even a gunship style conversion would probably be faster just as you have so much useable power. The Vauxhall engine was going to get silly as like a Yb its just too easy to sling a Gt30 on the side of it and go mad.
Car has been on hold for a while I setup a few other things, been out of work for most of the year anyway and with the house I've been MEGA skint
New engine is a dry sumped S2000 lump on Jenveys (when I finally put the order in for them !)
Cheap reliable and seriously grunty for not a lot of money, I don't need top speed and tbh I will be doing some timed stuff with the car now anyway so it needs to be setup for that, not to impress the internet massive

, and had done 40,000 miles, so 440ish?Also, I didn't struggle to get past you, I struggled to stay WITH you
. I drove my tits off and this was one of my most memorable track sessions EVER . If you remember, Fast Ford had put the cameras in Justin's car for their DVD footage (as he had 512bhp and an R&D dog box), so the theory was he would keep up no bother.
Even with him on R888s, we gradually pulled away from him and he finally gave up and pulled into the pits, as with the standard rear beam, his car was not giving him the required confidence to drive like we were
.You also seem to be forgetting I was on road tyres and you were on full Michelin slicks, which made things amazingly even
. Rest assured, I have a set of slicks myself now - as I couldn't believe the difference they made .

Mike/Dave, you BOTH are very good drivers imo ( not bum licking either) and that makes a HUGE difference, i,ve seen guys driving stage 3 cars much faster than BIG bhp cars all because they,re better drivers, PERIOD.....
When we was @ Combe this year i,ll not forget SI B in his 590bhp Evo going against the guy in the 500bhp 3dr and he was with Si even passed him and let,s be honest, Si isn,t a shabby driver is he??
Anyway, i,ll stick to my torquey GUNSHIP......
Mike, i want a passenger ride with you this year somewhere too i promise i,ll not feel your leg...

Because with a larger turbine, you get less back-pressure, and this allows higger compression ratios to be used.
At 2.2 bar on a T4, which uses a comparitively small 0.63 a/r turbine housing, the back pressure is well into the 50s, which heats up the exhaust valves and combined with high compression, this is likely to lead to a temperature of these that would induce pre-ignition or even in an extreme case, melt the valves.

At that point, when the engine was new it was only 477bhp , and had done 40,000 miles, so 440ish?
Also, I didn't struggle to get past you, I struggled to stay WITH you . I drove my tits off and this was one of my most memorable track sessions EVER .

Danny have you built an engine with a roller T4 and Hart plenum, looking at the prices you listed a T4 would work out around the same as a Gt30 time you mod the manifold,external wastegate....
If i was to ever do it again i would be going to Tony or SCS as there two builders that have tried and tested packages.

must add to this thread and say......my 430bhp engine was "built" by a man in a shed, granted the machine work was done by Ahmed but the engine was put together in a shed and on my drive at home......and its been ragged to death for 3 n 1/2 years now........the only "engine" thing to go wrong was that the heads gone porous/soft..........but that aint the builders fault is it........i'm not saying it would have been fine at 500bhp cos i dont know, but with head work (+1k) cam (Ł200)and different turbo(Ł400 extra) the job could have been done for a less than Ł5k.......just my opinion.........

I have another question. With all these high powered Cosworths (especially in road cars) how much does it effect drivability? Is certain power too much for the road? Would 400bhp be better on the road than 500bhp? Of course how the cars suspension is set up will contribute to how it feels on the road. But surely there is a limit?

With regards to driveability, Dave's engine is fine to drive around off boost, the longer throw crank makes it torquey, its just a lovely engine to drive in every respect.
700bhp+ though means getting up to speeds that you can struggle to get rid of if you arent sensible where you use it im sure.
My car is a lot slower than Dave's but Ive had moments in it where Ive become aware im going too fast for the circumstances, its easily done!

On a road car, there isnt really a lot of point, a basic 4 pot setup on reasonable size disks will out perform the tyres generally.
