nearly forgot about the incident with Julians car (i think it was his))when something shot out of the exhaust and nearly hit luke in the face

I've got some footage of that one tape

Well done Frank, great day - I didn't realise J-Tuner were going to be there too, will be good to see this one in a magazine some time.

The Mk1 pulled 102bhp at the wheels, which isn't bad for a 21 year old engine which has been mercilessly thrashed at trackdays for the last year and a half. The estimated flywheel figure I got was 136bhp, which I think was suprisingly generous for transmission/tyre losses - but its just good to know the car is producing the power.was

As for videoing - I was looking after the video camera and so didn't really get chance to chat to everyone as much as I'd liked to have done ... thanks to Paul Port and Super for minding it for a few runs

I've got 1 hour 40 mins of footage from today - its playing int my PC at the moment.

I'll try to edit up the runs people did, and upload high quality clips to the site here. Looking at the footage the sunlight through the windows causes some patterning on some of the footage, but it is good enough.

good run home ( you know who you are!!!!!)

got absolutely no idea jim

[Pete J]

Nicely organised Frank =D>

Great convoy and some awesome cars. Never seen so many CC's in one place.

Was it me, or was there a wide variation in calculated transmission losses? Seemed to range between 40 and 80 bhp guestimates

Anyone keep track of all the wheel bhps?

Only took a few pics on my phone and I promise I wasn't pulling a face when we were all infront of the IMOC banner

Once again, well done Frank.. really looking forward to yet another MR2 feature in J-Tuner =D>

Great turnout guys, was well pleased with my run (if it's accurate)lol
Was nice to meet a few IMOC'ers.

I got 237 at the wheels today

at the wheels is where it counts ... so 237 at a smidge over 1bar boost a nice number

I'm well chuffed (hence my silly jig under the cossie )

Yep, I put my hands up- It was my car that shot the birds nest out the exhaust and nealry blinded Luke with soot and cr@p

I am recovering now from my naff run and am hoping I get it sorted very soon. As soon as I do i will post back up what was wrong

Was a great day tho and nice to see so many cool cars

[BenF]

The transmission losses will vary with the power that the engine is generating- its not a fixed amount, and should be calculated on the roll-down after the first run.

The best figure to use is the one that is measured at the wheels - there's no argument about these.

If you need a figure at the fly, generally for my old Mk2 Turbo I found transmission losses were generally calculated to be between 15 and 17.5% - so a 200bhp at the wheels is about 235 at the flywheel.

If you need a figure at the fly

Need.........only time you'd need it is if your wheel hp sounds crap and you want to beef it up

So is someone goona start a thread with ALL the results of the day!!?? What did Mark end up making!!?? I've been waiting for like a month for these results

Cheers

Well mine was cr@p and way down on what I was expecting......177bhp at the wheels .

What can i say to that except

[steve]

was a good day, i'll be running on the next one

[juliankv73]

Wish I never bothered but at least I know categorically it runs like a sack of spuds!

[KiwiMR2]

CosmosblueMR2 is onto it

i think it's good you did run mate, if you didnt you'd never have known

that UFO from your zorst missed me by a few inches so it's all good

Yeh TBH, you both right, just a bitter pill to swallow and not throw up!

First I gotta get my new exhaust then start looking at the WHY, WHEN and HOW, then a new RR to check everything out.

Cheers fellas =D>

[juliankv73]

Steve, I thought I was using the Power of the Darkside and that the Force was strong with me!

The ONLY thing strong with me was the power of that birds nest and the black smoke pulsating from the zorst during the run!!

DEEP BREATH= AHHHHHHHHHHHH Bad black air, **AHEM** cough splutter,

[steve]

dont worry about it mate, your be back after some extra jedi training

[CosmosblueMR2]

Damn i missed the projectile out of the rear of Julians car

Ben - hurry up with THAT video - should be a great IMOC moment

Julian - nice to meet you mate - hope you had a good day overall despite your dissapointing figs... at least it gives you a starting point.

can only get better now !
