And if all goes to plan this week, there should be an extra special Exocet on the grid....
Just need to crack the whip some more

If you're cracking the whip, who's doing the work? Have you got Sylvie chained to a workbench?

I look forward to being lapped by one of our own. I suppose we'll have to change the name a little.

[Stiggy]

tell us more about this extra special Exocet then... has it got a fan on it?

[johnp]

Someone must've blabbed! Remember the Chaparral 2J from 1967? It used a snowmobile engine to power fans for 'ground effect'.



We've added two 12volt leaf blowers - one to mutiply inlet airflow by a factor of 8 to 10, the other to provide a partial vacuum within a rubberised skirt beneath the floorpan, giving a downforce equivalent to 72Kg. It is intended to convert from 98 octane petrol to 110 octane wood alcohol, but that's still a work in progress.

[Stiggy]

does it cause cars to hit hard objects that require stitching with cable ties?


any guesses what this modified Rocket has sticking out of the front cover? I could not understand how the scrute let it race like that. My guess is that the rain screen was increased, as the pipe was taking air/rain from the grille and up and out on the passenger side, naughty naughty!


A little wet out there, MEV's dominating the Sports Special grids. Well done guys, have a great day!

We had fun in the wet - faster cars spinning off all over the shop! No video from me but there are two from Micky Scott.

It's possible the links may not work for you - if they don't let me know and I'll try to sort it.
Reworked link - Micky Scott's vid. click on either of the top two for Dony

Man it was slippy in the morning! Close to 200bhp ATW in a MEV means gently gently when exiting corners!
I managed to light up the tyres in 4th and crunch into the wall Why is it whenever I go to Donington I need a new nose!

Most frustrating part was we replaced the Cam sensor with a 1.6 version and couldn't get the timing set correctly. The Megasquirt was set for 14 degrees and we reset the ECU to 10 so no wonder it wasn't as quick in the dry as it was in the wet earlier on!
It does sound good on the videos though

[Stiggy]

videos please, pref lowish res so my old PC can cope. Picture of engine bay perhaps?

[Stewart]

That stupid GoPro only recorded the wet race
Mind you we were sat waiting for 1h30 minutes for race 2! They'd ran out of ambulances!!

[Stewart]

Quick snip of race 1 - conditions were monsoon-like!
MX150R in front was standard power, mine I think was down on power after replacing the CAS with a 1.6 version and not being able to set the timing up properly.
