Hi guys I thought it might be cool to see everyones dyno results on 1 thread.
I'll go first:

Model: 340 GL Williams F7R
Max power (BHP)@Wheels: 166.7 (5891 RPM)
Max torque (NM)@wheels: 209.3 (4127 RPM)
Top Speed (MPH): 139

Keep it going

Nice! Haven't dyno'd mine yet, but assuming yours is a standard f7r engine (same as mine) it should put out around the same power. Would be cool to get mine on a rolling road though!

Never got around to dynoing mine but taking into account the cars I was winning/loosing to and 1/4 mile times I estimated it around the same as you.

Is F7R lowly cammed as power comes from such low RPM or is there some work left to do?

I would imagine that well breathing 16 valve should have 6500rpm or more as peak power?

6500rpm is the F7R's rev limit. Surprisingly low for a 4 cylinder. It's a popular thing to raise the rev limit to 7/7.5K and have a re-map.

That is interesting, for me it sounds like if there would be some potential that could be unleashed as it is such, how much re-map and increasing rev limit gains in terms of power?

Intake/exhaust runner length and diameter might need some work to get most from higher rpm of course as those are probably made for lower rpm by factory.

The issue you have Jani is the F7R is just a stroked F7P, it'd take a bit of work to get it to rev much past that and not break stuff.

The 1.8's (the P's) are much better at it.

So it is bit like redblock with marine crank which makes it bit poor revving and it requires quite bit of work to get most of it.

I knew that there has to be some issue because of such low rpm max power

I have a superchip and am planning a remap but it's on hold as I don't want to get greedy and end up blowing it!

good results. any idea on what a f7p puts out compared to the r i was thinking around 135 but thats just a guess
