Snowy's Production Sports R35

[Snowman]

It will be my very first race. Excitafraid is the term we have created for how I'm feeling about it

We have another new addition to go into the car - the new Motec CDL3 track kit with the upgraded SLM.

Basically these can be configured to go into any car (no Motec ECU required) but are really easy for cars with an OBD port / CANBUS system. GPS based lap timing with automatic track recognition so no more putting becons out or programming the unit for each track you go to. The SLM can be programmed to give warnings for any settings read through the canbus or any other interface you use. So you can set warnings for engine, transmission, water temps, knock - whatever you like really. And it obviously acts as a shift light as well. Plus the I2 software is as good as it gets for data analysis when looking at lap times and comparing things like braking points at even lines through corners with the GPS tracking.

Another thing I've had to get was different sized uprights for the Aeromotions wing. Regs state the max wing height can only be 250mm from the boot lid at the centre point of the car. The old height was about 295mm. With these new smaller ones it now sits at 249mm.

Excitafraid or not, you will have a lot of SAUers in support

if you get passed the grid, you'll be alright

I'll be there Sat or Sun to spectate.

[Gts-t]

This car is badass, looking forward to further updates!

I should have the cage bracket tomorrow Snowy, I'll drop it off at RacePace.

Hey snowman, not sure if your gonna add a front splitter now or later but curious if running the lower uprights gives you less rear downforce. It may end up balancing the car and loosing that under steer you have.. Not sure but would like to hear your feedback if you try. Cheers

[Snowman]

Steve - I want to run a front splitter and I have one ordered from Powerhouse Amuse. Unfortunately it's not due to arrive until August so I won't have it for the first event.

I hope Miles doesn't mind me using his pic but this is the same unit as he runs on his beast. The main benefit with the Amuse unit however is in their under-side design.

[blackrex]

I saw your spare gearbox at Trackart yesterday Snowy, no wonder your Veyron weighs so much, the gearbox is massive.

[Snowman]

Gearbox also includes the transfer case and rear diff. So yeah it's massive.

[stevena]

That front splitter will definitely help, it's great that you can buy one already fabricated to fit your vehicle. Since you won't have it on for the first event please give feedback in regards to front grip, not even sure if you will feel any difference but still curious.

More work has been done. The event I did earlier in the year at the Australian GP showed a continual rise in engine oil temps over +15min runs to the point where oil temps were getting to worrying levels so a second oil cooler has been installed into the centre of the car similar to the pic below (I don't have pics of my set-up unfortunately but this image was the basis for what we did)

[Snowman]

The other big issue we have faced with the car to date has been brake temps. To date there are no real brake ducting solutions available for the R35 so the boys at Racepace have come together with the fabrications guy at Kelly Racing to design a custom brake cooling duct. At the same time they are also designing one for Chris' R33 GT-R.

Again I don't have pics of the first step - but that was to come around with some balsa wood and sculpt the basis of the shape for the duct mould.Once they had this they were able to cast the initial duct which was deliberately made oversize in length. The construction is also made with a special high temp resin that is also designed to self extinguish in the event of a brake fire. It's the same stuff they use on the V8 Supercar duct construction.

Next step was to check clearances with the wheels at lock.

The calliper and rotors were then removed and the duct is trimmed to make a neat fit on the back side.

Then the calliper was bolted back on and the front was trimmed to match as well. This intersects right along the edge of the calliper so that there is clearance for the brake lines.

Next step is to show how we are collecting the air into the ducts and I will post that up when it is done.

[Snowman]

Another shot of the brake duct now that the calliper and rotor is in place. Can also see the brake water spray kit at the front.

Motec CDL3 dash has been mounted as well.

[No Crust Racing]

This is awesome stuff Snowy, I'm really looking forward to you getting back on the track.

[JZP]

Ballpark $$ on the Motec setup?

Edit: just googled it... nice bit of kit

[Snowman]

About $3K with the upgraded SLM.

[phunky_monkey]

Looking good mate.

What format are your races in? 10, 15, 20 mins?

[Snowman]

Dane - The state series are 4 race weekends. Sandown races are 8, 10, 10 and 12 laps and PI are 6, 8, 8 and 10 lap races.

The enduro races (Island Magic and Bathurst) are again 4 race weekends but they consist of 1 x 5 lap for driver, 1 x 5 lap for co-driver and then 2 x 1hr races with 1 pitstop each race for driver changes (no refueling however).

Anyways - I have some more car updates. I have the new doors and side window's back from Raceglass.

Rear 1/4 including the inner mould which the window sits in. Looks stock!

One of the front door window's.

One of the doors - total weight is 6kgs.

Inner side of the mould.

And fitted to the car. Color match is amazing so no painting or anything required.

[twinvl]

Looking great, even since I had a look a few week ago!

If you're struggling with any of the dash setup let me know. Also I can check your config to ensure you get the best data you can out of the CDL3!

I'll try and make it to the race in a couple of weeks too.

Cheers,

Darren.

Cheers Darren.

What would be SUPER would be if you had the CAN protocols for the gearbox so we could log what that is doing as well. I got most of the engine stuff from Lee but I don't have anything as yet for the gearbox.
