Nope.. Standard means Standard, not "fairly Standard"

Of course you can you have a standard(ish) car . I've chipped in and its a chim forum, did you mention that most standard 4ltr V8S's seem to make more than the equivilant Chim installation before .

I have a rolling-road print from My Chim 500 which is putting out 258bhp at the wheels at 5553rpm - what is this putting out at the flywheel?

So - anyone got an opinion of what my car is making at the flywheel, given 258 at the wheels?

If it was making that much at the wheels , which is still quiet a lot even for a fettled 500 then 310-320 bhp corrected IMHO.
Most 'standard' 500's make around 225-230 bhp at the wheels again IMHO.

my 4.5 was on the Rolling road at Mech Repairs last month and recorded 219 bhp at the Flywheel before the Mods were carried out. From all accounts their r.r always gives a low figure and this equates to approx. 270 elsewhere.

As a rough guess I'd say it's probably very close to 300bhp, if anything slightly over, which is a lot!!! My reasons for saying this is my Griff 500 put's out slightly less than that and the difference on Austec's RR was 41bhp between Flywheel and A.T.W figures. How about Torque??

Took my 4 ltr to austec a while ago and i seem to remember them quoting it at 230 at the flywheel.

Well if its standard 4.0 then Austecs RR is over-reading somewhat, or its the best 4.0 I've heard of

[Dave 500]

My 5.0L which is standard produced 247bhp at the wheels and somthing like 270 lb/ft.

Quiet a few of the standard V8S's seem to make 230-240, if not more. Whereas the chims seem to be nearer 210-220 as standard, but there are always exceptions IMHO, some even 190 ish which is sorted V6 S country.

Surprised a V8S owner in my old S... he didn't seem very happy about it either

best compliment normally is when you stop off after a 'run out' for a shandy and the question is asked cooly.............'whats under the bonnet' to which you reply [pies mode] its standard [/pies mode].

Yeah.. a heater...

[V8 Archie]

I got 240bhp/270lbft at the RR day last summer. That'll be at the fly though. (4.5L).

Print indicating 286lb.ft at 3620 RPM (once again at the wheels)

[stackmonkey]

If it helps at all, my Chim 500 Taraka was measured at 257bhp and 271lbft at the wheels at Holeshot, bradford less thana couple of weeks ago. TVR Power gave transmission losses at approx 20% (it's a late 95N car) giving engine figures of 320bhp and 340lb ft.

[dlewis]

Austec RR gave 252bhp and 291ftlbs for a little 450, which was nice.

Mind you it is modified it has AC!

Ah I see a 50hp AC plant, shame it doesn't cool the car very well .
Was that wheels or flywheel BTW .
