Dyno Test?

I was wondering if anyone has ever put their F-Car on a Dyno Test to see how the current BHP output compares with the original factory figures?

For example. Euro 328 quoted = 270 bhp. Current = ???bhp

I've heard of people who have done that and been told that they've lost most of their horses. I don't want to put myself in that position and find out my 270 horses are actually only 200 now

I have had it done on both a 308 GTB and F40. On the former the original factory claimed bhp was 255 and the current is 235 bhp. Not bad after 31 years.

Dyno of the 308 here (note, the car is for sale and well-prepped for the track yet street legal).

Thats cool. Thanks guys.

I remember seeing an episode of TG on one of their road trips. I think it was Italian sportscar under 10k (or some such thing). Anyway they had to put these cars on a Dyno test and as I recall the 308GT4 had lost the least out of all of them. I am beginning to think that the F-car is probably one of the best at retaining bhp.

Question is
what is the best way to keep the horses in the paddock? and
how can one recapture any that have run away?

Steven - what was the original bhp quoted on your 308?

1. Regular proper maintenance
2. Engine rebuild

Euro 308's were originally rated at 255 bhp and US 308's at 235 bhp. Factory ratings in the 70's could be a bit "liberal".

That must be why F-cars are good at retaining the horses - all that maintenance!

Boxer, how did the F40 do in the dyno?

did you test the engine out of the car?

and you got it right, those are the 2 ways to keep all the horses in there hehehehe

Engine was in the F40. It did very well on the Dyno. With the sports exhaust and LM Turbos it puts out close to 600 bhp.

The factory probably lied and said 255. i bet they were lucky when new to do 235 or so. It is like Ferrari 308 stock speedometers...

In the 70s the rating was probably flywheel HP not wheel HP figure about 10% or so Drivetrain loss
