Richos R33 Gtst

We did some wool tuff testing at Wakefield. Just to get an understanding of what the air is doing behind the car.

It's on some serious drugs. The wool between the bar and the body work was being sucked into the gap.

Awesome r33 ssxRicho I met you at Vic time attack on the Saturday. Was good to put a face to the name on here. I've got the same r33. Keep up the awesome work.

Cheers Josh

Finished off the wing end plates with some paint.

Expander foam worked. Still needs a sand and body filler.

Running out of time for Winton on the 3rd, so 12mm plywood slitter will have to do.

The splitter still needs all the mounts fabed up and the air dam fitted,

From that pic your wing end plates look as big as your doors lol. We also made some bigger end plates and used the 7075 t6 alloy i believe, as we needed something strong and light. What material did you use to make them?

[No Crust Racing]

lol I was having a hard time working out wtf was going on in that end plate pic, they look massive.

[ssxRicho]

Just out of 2mm alloy sheet. I'm unsure of the grade. They weigh 340g ea. Rigid enough.

They are pretty big (though not as big as the doors, they are the same ones from the previous page). Who knows if they provide any benefit, until we get them on. We're going to make up some smaller more convention ones as well, just to see what the difference maybe.

There is a theory that lowering the profile of the end plate after the gurney will increase it's effect.

does it make a big difference to cover up any holes not in use on the front bar?

[ssxRicho]

Yep, those holes produce a huge amount of drag and screw up the front splitter.

Front turn in and more so grip through higher speed corners is far more pronounced. It's spooky science shit, but it does work.

[No Crust Racing]

That's interesting about blocking up the holes, I actually cut holes in my bar in those spots and meshed it, one side to feed the air intake and one side to feed the oil cooler.

Will be interesting to see how my car reacts now with the splitter on.

[ssxRicho]

I'd imagine at PI feeling a difference.

[ssxRicho]

Another weekend on the car.

Changed pads to EBC Orange

[ssxRicho]

Oil cooler shroud

[ssxRicho]

The old man fabricated this entire thing.

[ssxRicho]

Then I had the fun task of completing the bar

[ssxRicho]

The rear wing is all fitted up

Car looks good mate. Another fellow r33 peddler.

If your splitter works well you may need to jack your wing up higher to get into some clean air flow so it can balance out the front. It looks a little low there. Usually flush with the roof line is a good height to guarantee unmolested airflow. It made a huge difference to our car when we did it.

[No Crust Racing]

What's the splitter material? Structural ply?

Your brake ducts look like mine, did you find they worked?

Yeh limited by class rules to the level of the roof line. That photo is deceptive, the end plate are level with the roof.

[r33_racer]

Sweet. Should pick up more downforce in the high speed cornering area.

[ssxRicho]

More work on the car last night.

NACA duct for oil cooler. Cooler needs to be angled a little, so that is the next job.

Slot in rear mounts for the splitter.
