I'm up against this car a lot and is one of my main "pain's in the arse", a heavily altered loosely described Evo in more ways than one. In his launch sequence he holds the blue knob which I presume is a line lock and presses red button on the wheel but not releasing that until he has got going. Is the red button same as a rev limiter used as launch control or is it launch control. Can't work out why his rev counter is reading max and bouncing off soft cut if he is using rev limiter. any idea's what's happening here. I use a rev limiter with button to control pit lane speed but thinking I should be using it in a different way as well after looking at my competition. I use omex stuff so I can multi task my rev limiter if I wanted to.
Edited to add : The sequence i'm interested in starts at 1.50 into it, 17.50 onwards for TVR action

I can answer that one Ivor, It's the famous in his own world "Gary Prebble" he has been GT Champion five times I think at Combe. His car is not quite as special as the worlds fastest Evo in the video but not far off. Gary has 780BHP with a computer operated diff that can be altered as you go worth in excess of 30k very handy in the wet he tells me. On the other hand Norris has 850BHP and money is no object his car is the best of that genrea around at the moment, both cars are four wheel drive. picture book of this car here looks like he has over 1000BHP on dyno graphs

(shame the driver still needs to catch up with the performance ). OOOOOh b
hy he cost me £1865 worth of repairs last time out. Formidable competition but TVR took the lap record this year, they don't like it up em.

I suspect the blue knob is line lock on the brakes and red button on the steering is launch control that looks like it is set at 8,000rpm, hence the limiter cutting in. It's not at max revs.
You could dual use your Omex pit limiter function, but presumably you'd have to hope the revs that match the max pit lane speed are also optimal for standing starts, or you programme it differently for races without pit stops.
But let's face it, you aren't going to outdrag him at a start, not with him having 4wd.
That Evo could be massively faster with someone a bit more, ahem, skilled behind the wheel. He's on and off the throttle into and out of corners, coasts into braking zones off the throttle and off the brakes, doesn't pick up the throttle early enough n corners, his lines are variable, he changes gear all over the place - almost at random sometimes. Going into Avon Rise one time he selects 6th instead of 4th If the car didn't accelerate so rapidly he wouldn't get away with all his mistakes.
If he spent some money on tuition you'd be in real trouble!

Hi Andy,
I think the answer is to set up a separate Omex launch control box although I'm no slouch off the line. Omex rev limiters set up properly are a no brainer, cheap as proverbial ....s. I agree the 4wd cars arrive at quarry 50 yrds in front which takes most of the 20 mins getting onto the bumper let alone getting passed. In the wet you can forget it.
why is he hanging onto the limiter ( I take it launch control is just a rev limiter wrapped in a fancy name) I guess that the duration must be manual or has he not slipped the clutch out properly ?

Yes you're right, it's just a temporary reduced rev limit, the idea being you set it at optimal launch revs, hold at those revs, dump the clutch then release the launch button when you have traction. From the video Norris uses 8k in the dry - shows how much grip he has!I think the answer is to set up a separate Omex launch control box although I'm no slouch off the line.
