RE: PH Fleet: Tested On The Rolling Road
Discussion
Can you remember what sort of figures the various Rover V8s usually produce Vixpy?
Do any of the 500s actually get anywhere near the 340bhp or whatever it is they're quoted at? I presume all the figures quoted in this thread are estimations of the flywheel figure rather than rear wheel horsepower?

Chim/Grif 400 : 190 - 230Do any of the 500s actually get anywhere near the 340bhp or whatever it is they're quoted at? I presume all the figures quoted in this thread are estimations of the flywheel figure rather than rear wheel horsepower?
450 : 250 - 270
500 : 240 - 290
As standard anyway, depending mainly on how worn the cam is

I'm wondering why mine seems to be producing so much power now?
Prehaps this is a good example of why its worth paying that bit more for older peformance cars from dedicated specalists.I stress this is not a reference to whoever Garlick bought the car off, but I found secondhand TVRs varied hugely from one-to-another and not always with correlation to who was selling them or how much they were charging. Likewise for servicing, price is no guarantee that they won't leave the car out in the rain to fill up with water and then fail to tighten the wheelnuts properly (leaving them to come loose at speed) as one expensive and generally well-regarded TVR specialist did to me.

Couple of Points
1) Pauls Chim is the best standard 4L I've ever done, and I've done about 200 of them (thanks for the cheque Paul)
2) The 460/470 I quoted for the M6 was because it was running normal unleaded, On super the V10 almost always does 500bhp.
Vixpy, what did the M6 do at the wheels ? Thx !1) Pauls Chim is the best standard 4L I've ever done, and I've done about 200 of them (thanks for the cheque Paul)

"Kinda curious, but do you use correction factors or are all the figures STD? Also are they metric or Imperial?

Wasn't trying to pick holes BTW (encase it came across like that). Just I guess I'm a bit a geek and find this sort of stuff interesting...

Big fan?
There's a bit on the BBR (MX-5 turbo and tweaked BMW Mini tuners) website where they mention not to rolling road forced induction engines due to the lack of air compared to when the cars are rolling.
Rolling road forced induction engines isn't a good idea?
Do you think that could be a bit of face saving?There's a bit on the BBR (MX-5 turbo and tweaked BMW Mini tuners) website where they mention not to rolling road forced induction engines due to the lack of air compared to when the cars are rolling.

The only way to really know what does what is to take it to the strip but a dyno gives you a good indication if they have nothing to do with the tuner.
Charlie has RR'd mine and the intake temps didn't get anywhere near silly.

Agree fully. Also a dyno should be used as a tuning tool to allow you to load the engine, monitor and adjust while measuring AF ratios more than just the torque/power curves.
