Personally i think i deserve a medal for driving Colin's car that quickly

[Modena Scotland]

Yep, Colin's blue 340R was very quick on the straights.

Thought I was keeping up with you ok through the twisties Mass

lol...you don't need a 340r to keep up with Mass-destruction

Mass-destruction WILL not happen. All fingers crossed

Joking apart, this new engine feels good.

Back in your hole.

Gareth, if you have calculated you need a beem with a surface are of 100mm squared. What size of beam can you use ?

You've been playing with Colin too much.
Your posts make as much sense as his. i.e. don't make sense.

Me and Brian (link up 340r) were on track at the same time and it was considerably quicker, hope he doesn't mind me saying that. ....

I was surprised how quickly it pulled away leaving the hairpin.

I'll just need to check it into the Gourlay garage for some of the same magic!

Cheers

Believe yours is a jdm engine, so an over the top manifold and maybe an rbc inlet with mapping should get you close. You have a longer manifold with jdm anyway so the exhaust and mapping should help.

Colin has custom cams which help things along....

i got 235 out of my uk spec engine with a inlet manifold and a 2bular over the top system.

Sounds about right, so the cams are giving an extra 10 bhp. It all depends on the dyno as well, its better to compare apples with apples.

mine was done at Destek in fife, think they are the same type of RR?

Doesn't really matter though. Different place, probably different calibration, different temp, air density - that all makes a significant percentage difference when you're talking about 5-10 horsepower.

to be fair we are talking about sanjoy and colin so its not going to make any difference.

[Shug]

It does at the bar...

[Gourlay83]

My car at the same rolling road made 195 bhp at the wheels (lets forget engine horse power, whp is the figure you use) Colins made just over 215 bhp. So the better cams and manifold made 20 whp which is a good reasonable increase. That's what I was meaning with "comparing apples with apples"

I've heard people say there standard engine with an exhaust makes 250 bhp, complete Bollocks imo. Some dynos/tuners seem to get these high figures but what's annoying is everyone compares the figures to them.

Alan,
Do you use the Emerald ECU in the Honda conversions ?

You can fudge those figures easily if you use wheel horse power. Tyre pressures and stuff make a major difference. That's why a decent operator uses a run-down measurement and not some arbitrary percentage fudge to get flywheel horsepower - that's about as close as you'll get to a level playing field. Of course, the only properly accurate way is to bolt the engine into an engine dyno with the same exhaust as it uses in the car, but that's a touch silly...

[Gourlay83]

The Wallace performance dyno is a dastek and uses coast down to calculate engine horse power.

I agree with what your saying though, some of calculated engine horse power figures I've seen are just wild.
