[misc_work] Still Nothing To Do With 205's...

[Cameron 16]

Fundamental principles of Motorsport awesomeness.

[Rippthrough 98]

Just gotta work out wtf to do with the front, but then traction is a priority so I'll worry about that later

[Rippthrough 98]

Cameron's gonna have to get some tissues, I've just finished some rough and dirty cfd work and I think it's gonna end up as a 3-element wing instead with a leading slat/flow conditioner.....

Oh god that's filthy.

[Rippthrough 98]

If it were in ideal circumstances, it should be making over 170kg of downforce @ 70mph.

More realistically, given the operating conditions from the flow off the car, probably looking at around around the 120-130kg area with the relatively benign stall needed, (given the amount the body moves around!)

Should be a noticable amount given the car is ~600kg at the rear, even if it's not life changing drive-on-the-ceiling amounts.

Some progress, secondaries mocked up, right length, but needs a couple of tweaks to the shape before welding to smooth the flow a little:







Side profile of engine/cage now, that's the old engine rear protection cage for mockup there, you can see how much longer the old setup used to be. The top bar used to be horizontal too, so you can also see how much ground clearance we've gained!







And some of the mountings and plumbing done. Yes, that alternator IS going to be a bitch to drive.
I know the air feed into the plenum and out of the charger need a bit of work but it's a case of make something easy that works at the moment and improve it later

Mental, as in just crazy! The size of that radiator what's it off!?

 

Really look forward to some videos of this.

[Rippthrough 98]

Err, was designed for a 600+bhp skyline originally I think, it worked well enough with the rotary anyway so it's staying.
Just needs a new cowling now the mountings have changed!

 

Actually, if you want a rough scale, that's a pair of 16" fans sat side by side there.

I assume you're hoping to have it ready for the 2013 season? Might come the south Wales event in April as that one of the only weekends I have off over the summer!

It'll be ready for this season, just probably not the first one or two!
Good fun next week 'cause I've gotta wire the bitch up....

:0 Awesome! Looks like it will be mega fun with a set-up like that.

[Rippthrough 98]

So long as it stays in one piece!
The CV joints are a bit of a worry at the moment but we'll treat them to some uber-grease and see how they go.

That's one BIG inter cooler, what size pulley are you using? Boost?

What do you use Phil? I was looking for a superior alternative to regular motor factors moly grease but didn't come up with much.

[Rippthrough 98]

Millers Hi-Mol 20 is the usual Tom, far higher moly content than 'factors CV grease (Which is usually around 2%), it copes with higher temperatures better too.

However, managed to blag a small canister of some Tribolube stuff designed for driveshafts and swingpins military jets, which actually coats/embeds into the steel surface whilst it's being worked so it still works even if the boots get water in:



So I'm gonna give that a shot!

[Tom Fenton 1,525]

Thanks Phil, I've ordered some of the Millers gear to try, it has to be better than car spares boggo grease, the problem I was having especially at the 'ring was heat from the brakes making the CV joint grease turn to watery crap, hence knocking shafts towards the end of a hard lap. Drive the car gently back to the digs and by the time you'd got back the grease had cooled down and the shafts had gone quiet again.

[Rippthrough 98]

Yeah, we've had that when we've had to use it as being the only thing to hand, soon learnt the lesson on that one after pouring it out of the boots like water...

[Rippthrough 98]

Who put a tube there?



Okay, not the best solution, and finding a belt will be fun, but, the only way to do it:



Starting to look a bit tight in there now!

[calvinhorse 870]

Looking awesome Phil

[Rippthrough 98]

Looking like being ready for 2022 season more like.

[Rippthrough 98]

New engine cage + extra sump protection to try to stop the sump guards bending as much:

[TT205 42]

Hats off to you Phil, there's some major work going in to this!

[Rippthrough 98]

Here hoping it doesn't go 'poof' the first time we hit the throttle eh?

[Rippthrough 98]

And a shiny pic to show just how much work went into moving the engine + box, lots further forward, a touch higher up, different mounting angle, transaxle casing modded so it could go nose-down....



versus the old:

I certainly see why it's dry-sumped
