985cc Turbocharged Nova Sprint Car

Yes, that looks good, although I think I would move the vent toward the rear of the wing, as it is on the Clio?

i did it that way 1st, i was thinking you ment the black piece at 1st.

Brilliant, thanks Keith, that's exactly what I had in mind. I like it.

I do intend to use the black vent piece as well, but I don't have the one for the nearside wing, unfortunately.

are you trying to copy some aero mods here Colin? cut down the pressure caught in the wheel well?

Certainly that's where my first thoughts were, but I also like the look of them.

I'm now wondering if 3D printing might be of use to me here. I've never really come up with a realistic use for one, but in this case I guess one could be used to create a mirror image of the vents/surround to use on the opposite side of the car.

Anyone got a 3D printer, or know someone who has and would be willing to create some replicas for me?

If you want to drop the pressure in the rear wheel arch, vent the top of the wing, and lose the entirety of the back of it, venting won't do much as there's still a solid surface for the high pressure to sit on, and allowing the air to flow out like that can actually stagnate the flow on the other surfaces, causing the pressure to be higher... sounds backwards but that's kinda just how thermodynamics works

Very hard to find an example as they're normally covered, but here, you can imagine it's almost like a large piece of hollow box section behind the wheel well, and that's actually no surfaces behind the wheel, so nowhere for high pressure to build. Early examples didn't have the flat outer panels to smooth flow along the car so it's easier to see, but I can't find an example atm.



edit: http://www.speedhunters.com/2013/02/...r-suzukis-s15/ check this out for aero ideas. Although I would have started with a flat floor and diffuser since that's about 30-60% of where race car downforce comes from and the CoP from doing that is generally quite central.

looks like it will fit nicely with a little work, nice! and good shout on the box, i believe BigRon on MIG has a source for round nose bearings to fit the hydraulic slaves, will ask him and let you know...

Lee - any luck finding out about the round nose bearings?

[lee303]

****, totally forgot, sorry, will try to find out this week

[novarally]

Did some stuff to the gearbox today, fitted the hydraulic release bearing, and gave it a coat of paint;











I still need to find a round-nose clutch release bearing if anyone knows what the answer for this is (Lee?). Thanks.

Glad to see this is still plodding on, Hopefully we can get back to daily updates soon - One of the best threads IMO

Thank-you for the encouraging words.

'Plodding' is exactly what it's doing at the moment, until I get my new garage built it's not going to make much progress. And then I need to find the money to pay for the engine upgrade which is currently going on at Brett Sims Motorsport.
