Just got the car back from the rollers

[Daston]

Car went in for a new head over the winter, with her ran in the guys at Dulfords wanted to give it a run on the rollers to see what figures it was putting out. With a new head, fingers and cams she put out 342bhp and 300ft/lb torque. Will get the dyno sheet scanned in.

thats a standard 4 litre?

Sounds pretty much on the money, must be pleased??

That's none too shabby Dave.

Yeah it's still enough and pretty much bang on what it should be.

Who was planning that turbo kit again ??

At the wheels or fly ? - presumably at the fly

Flywheel

Here be the graph

seems to be a good power curve, surprised the torque peaks at 4500 would have expected it to be higher

Looking at the graph peak torque is at 5900 rpm where the arrow is i should think that it should pull a house down with peak torque close to peak power .

Why didn't you run it to the red line? You've almost got another 1000rpm to go? Peak power on mine is at 7250 rpm.

Not sure I wasnt there at the time, good question to ask though, did wonder why it stopped there.

[dpd3047]

wheres the other power graphs that were on here last night?

If you look at the graph the power flattens out between 6,200 and 6,500rpm so they probably thought there would be little point in revving it higher.
