Just wondering when say Daz has got 345bhp is that at the flywheel ? If so what would his true reading be at the wheels ? There's a lot of numbers out there is everybody not going by output of the wheels ?

Plus, some rolling roads seem to give differing outputs. My previous N/A build gave 285 on one dyno and 260 on another. [My present 458 was taken on the latter] Also, differing RR's have differing losses calculations. Most figures banded are at flywheel.
Should be a gud'n this argue

What? confused

Oh, are you saying it's more than your wheel figure and as our engines are near similar is it down to the extra bits I've got? Don't forget my heads are stage 4 too... We're also I suspect running different CR's. So in fact different heads, different cam, different induction set up, and different CR.

Please can you repeat the question?

I`m sure Rob told me they were stage 4`s and my comp is 10 to something . Its your cam , induction pushing it up and the dodgy dyno laugh

Right, let me get this straight Daz, you think Rob said your heads were stage 4 but you're not sure. Your compression ratio is ten something, but that's all you know. And then you accuse me of using a dodgy dyno.

This is unwarranted abuse, I have witnesses, and I demand an apology.



p.s. guess who's not getting a cheap triple plenum this year. Or next year.

You know as much as me ! did you get a build sheet ? I don`t think you would get 345hp with stage three heads ,look at Peter`s 5.5 with stage three`s ,it produces less hp than mine ,well not for long rotate

Yes but that's got nothing to do with you, it's between me and my girlfriend.

Anyway, can't believe after 15 posts I'm still the only one that's posted RWHP......

Well, if the figures are as accurate as some of the claimed CRs, that's prolly not a bad thing...
