Race Car Prep Started

Started the prep on the Clio ready for start of season inspection at the end of Feb.

Have dumped the standard recirculating breather system and replaced it with a proper catch tank setup for engine and gearbox, mainly to reduce inducted oil mist and the issues that brings.

Gearbox oil cooling components have been decided on and will be ordered on Wednesday, the Sadev sequential box really needs cooling for endurance use (Clio cup races are only circa 15 mins), oil cooling setup is very simple, single point scavenge and single point return with Mocal 13 row oil cooler mounted on the front crossmember next to the rad. Oil is scavenged and pumped back to the box via a Tilton 12V oil pump.

Filter was an interesting one, standard Cup runs a Clio V6 airbox in place of the battery..... however the inlet for it is about 20mm away from the back of the headlight and as such flow is limited, I suspect by design to put a cap on max air induction capacity as Renault are very tight on what people have done to the air box etc. in the Clio Cup................. we don't have those regs though :)







Much better ;-) Heats not an issue as that area of the bay is as cool as it gets, we may whack a NACA duct in the bonnet if the data logging indicates any issues. The plan is to duct an air feed into the filter area from the high pressure zone in the wheel arch so flow should be more than adequote.

Yep, proper serious work! Need to get the brake cooling and rear wheel bearing cooling sorted as well! The rear wheel bearings will be fine as they are for the shorter races, possibly even the 4 hour races but I can see them dropping apart in the 24!

Nathan, if only there was room ;-)

First testing in this spec is the day before the first race! It'll be fine! We've done a lot of testing in standard spec and the change to Dunlops shouldn't be too bad as there is a tyre which is a close spec to the Michelins, albeit with a longer warm up time.

Gearbox oil cooling setup sorted and on its way. Thanks SJM you're excellent.

Turned up some interesting info today, this box has been used in a 24 hour race and completed the distance no problem just needed a pinion and crown wheel afterwards.

We're looking good here chaps!!!

Cheers
