Two vids from the RR day, will take the head off this week to get the guides and stem seals changed (cause of blue smoke). Its also running a BIT rich

Made 232.3bhp @ wheels and 252lbft, had to run it in 5th gear as it was too low so the front subframe was supported on wood, kept spinning up as boost came in. Got it to grip by adding the weight to drop the back end..

Nice and low

Nice amount of torque and it really spins up at high revs

It's now as low on the back as my vitesse

Does using 5th gear mean it was reading lower than it would do in 4th?

232bhp at the wheels!? :eek:

What do you reckon that is at the fly?

Says 260hp here but thats only a 13.3% trans loss. This was with me and a mate jumping on the front when it came on boost to sit the wheels in the rollers as the engine lifted, we did jump off though for the coastdown to stop the box rubbing on the roller. Without the wood under the subframe the gearbox was scrapping on the roller all the time! Don't know if jumping off reduced the coast down. Operators said the engine felt really sharp though, probably due to the lightened flywheel.

I turned the boost up to 14psi from 12psi too but I think heatsoak was an issue on the dyno, On the way home it was definately noticable. 14psi makes it quicker than an m3 csl

Missed the @ wheels part :eek:

Very nice power as well

Definitely! That's a great result Simon - bet you're chuffed! :cool:

I have to say since giving the MX5 a few extra ponies it certainly makes playing with people on the road that little bit more fair

Can't see 13% transmission loss being realistic, that thing has got to be putting out over 300 at the fly.

This doesn't help me and my hankering for something with a turbo

Wouldn't surprise me. It really does feel invincible on the road. Never been in any other car that pins you in the seat when you floor it at 100mph.

I got took out in a 310hp Evo6, It felt awesome in first gear after that i was a bit disapointed to be honest

Certainly wouldn't be happy if i 'upgraded' to one

That's awesome.

Only about 50bhp less than my M3 and way less insurance cost I should imagine. I'm so tempted.

How hard would it be to get 300BHP?

Is that even possible on a standard turbo, doesnt it have massive turbo lag or heat issues or some downside to it! :mad:

even with "only" 260 bhp at the fly its gonna be fast as the rover is not exactly a heavy car...

:cool:
