Can't tell from the video, but it didn't sound like you were revving hard enough between gears on the downshift.



Yep, more heel needed in the heel-toe braking.

My new undertray us much stiffer with the honeycomb core. I have another idea about fixing yours more easily, so it locks in place when you install it. It was the original idea for the one I have on my car. I'm away at the moment. Give me a call after 14th May and I'll explain.

I feel it was more to do with tyre pressures. Third session with higher starting pressures and the problem disappeared. I am also quite out of practice though...

Spent some time on the car this week. Cut up the drivers side guard, made the fibreglass inner guard and modified skirt, and made the side undertray.

I also fitted some 19mm ally box tube across the back of the front undertray to try and solve the sagging issue. I still need to patch the wear on the centre section of the diffuser, but it is all a lot stiffer.

I have also made up a mould to make a new engine undertray that will meet up with the rear of the diffuser. It will carry the side diffusers shapes and then turn some of that air in towards the brakes. It will simply bolt to the two sub frames.

I am still undecided on how to fit in the brake ducts and hose.

I should clear this up:

I still haven't figured out how to fit the brake ducting in and around the diffusers due to the fact they take up a lot of the available space behind the front bar.

If I figure it out, then yes, I'll probably use cable ties somewhere to hold the scat tube in place. I am trying to find a way to incorporate the ducting into the diffuser by boxing a section. This will increase the stiffness of the diffuser out of sight, and possibly provide a rear mounting point for the whole assembly.

I'll take some pics when the car next sees daylight.

Unfortunately I am now re-thinking the entire side skirt. I am thinking about making a set of side skirts to join my flat floor in such a way that there is a natural rake, or dare I say it, a small 'ground effects tunnel' on either side of the car. A few degrees (2-3) would do it and should aid in lift reduction.

Similar, but not quite. I want the actual flat floor to increase in distance from the ground as you move to the rear of the car. Sort of like a large but gentle diffuser. The skirt will extend down past the flat floor much like they do in NASCAR, except mine will have a more boxy shape to meet up with the stock body width.

Yes, I have been reading race car aero articles about the banned ground effects days in F1 etc.

The current setup is close, but the Vertex side skirts (or whatever they are) have a curve downwards at the rear end which is messing with my chi. I am working on a 'cut and shut' solution just to get it on the track to see what it goes like. Won't be pretty. Much like the rest of the car...

An engine undertray? I owe you one. Consider it done.

I'll tidy up the mould and get rid of the wrinkly edges at the front- it was done with electrical tape and some foam, LOL. Just wanted to see if it would go together OK. You need to fix it to the car somehow- I just welded some nuts to the frame and bolted it up.

Walter,

I hadn't thought about it. I suppose I could. not sure how it would work without the splitter and diffuser setup.

Basically it is a flat sheet of fibreglass with a one inch lip all round for structural rigidity that has two recesses to match my front diffusers. Anyone could make it.

Postage will be a b!tch though.

LOL. It only cost me $250 and some spare parts to get it mobile.

It is now in the shed with the track car. When I find some time, I intend to weld some casters (well, jockey wheels) to the chassis so I can take my suspension stuff back out of it and still move it around.

Those of you with a keen eye will note it does not have a sunroof, and the rear panels are straight. It also has no accident damage, no doors, no guards, no bonnet and no bumper bar- all the stuff I have already customised. So the car is a perfect match for what I have already.

The first intention was to find a wreck that I could cut the straight sheet metal out of to weld in to the track car. Then common sense went to see what that noise was, and I decided that I might build a carbon fibre/fibreglass roof and rear guards. This car will be the mould.

Of course, anything on the shell needs to come out, so I should have some cheap spare parts for sale soon (ABS, complete rear suspension and open wheeler, some front suspension parts, big plastic air con thing, roof lining etc). Not looking to make a killing, just cover costs.

Stand by for missus Lipman update...

Yeah, as good as could be expected. It isn't the money (really it is two and a half tanks of fuel) but more of a "this house is starting to look like a white trash, redneck, slum" kind of thing.

I have the track car and the shell in the garage, a bunch of fibreglass moulds in the back shed, boxes of Soarer spare parts and wiring looms in the side shed, two trailers in the front shed and a whole heap of doors and bonnets etc out the back. The red car sits on the drive. She might be right...

Welded some jockey wheels into the spare shell this weekend. I thought I took some pictures, but cant seem to find them...

I also got hold of a new rear wing. It is from a West sports/race car, and the guy I bought it from (runs a bunch of West Race Cars down here) was very helpful. He let me check out all the aero etc on his cars.

Wing came with mounts etc but will need end plates made up. Looks like I am going centre mounted after all.

Measurements are made by ruler/tape measure. The seller had no data, only test data compared to other wings he had.

span: 1560mm
chord: 276mm
thickness: 46mm (16.6%C)
adjustment range: 12 degrees with supplied mounts, which are 160mm centre to centre.
It is constructed in the US in an autoclave from dry carbon. (so it is bloody strong and light and shiny!)

I have just tacked it to the rear sheetmetal using some angle at the moment whilst getting the position right. Seeing as I have no rules to comply with, I have sat it back far enough for the boot to open on the factory hinge.

I am working on a mount (using scrap around the sheds) that will solidly mount it to the box section in the rear of factory boot floor. If I need to I will also run rods from the external part of the alloy mount through the bumper and back to the steel body work.

My greatest concern is how close the centre mounts are to the centre. I am concerned the wing will "wobble", even though this is how they are mounted on the West cars. Making these mounts as strong as possible is going to be tricky. I could figure out an end plate mount as well just to hold it all stiff, but it would look dicky.

The car is 1800(ish)mm wide at the widest point, so the wing is not as wide as I was going to make. It is much wider than the current wing (1300ish).

I had a few to pick from, but the guy selling reckoned this would be the best for a sedan based car. The profile is not too far from some of the stuff I was looking at, except I was looking at more camber. There was a wider wing, but it was their 'low downforce/drag' wing. Interestingly they have played with twin element wings (of which I am a fan) but did not find any advantage to them and ditched the idea.

Some of my plans for the spare shell were validated by my talking to him and looking at his chassis' sitting around the shop.

Good stuff Ben. That box section at the rear of the boot is my choice for where the wing will eventually be mounted too. It connects directly to both the chassis rails, so downforce should be directly transferred. The box section is also robust enough to handle the forces we are talking about.

I don't think the wing will get any wobble, but an answer (if you find it is the case) might be to use stainless cable from further out on the wing back to the mounts to make it more stable.

Walter only problem with that is from what ive read you need to attach it to a boot latch or under boot to measure the downward pressure. Would it be possible to use on a solid mounted wing?
Looking great ben!
Possibly to clean up the yard there may be somewhere renting a large shed you can store and work on it. If you go with a couple of mates can make the rent worthwhile. There is some sheds here locally that you can fit about 10 cars with a bit of space between for 220 a week, if you went in with 4-5 people would make it about the same price as a storage shed. But be able to work on it whenever. I want to do the same but cant find enough people i know also interested haha

i gather that the unit itself measures downward pressure through deflection. so just under a mounting point might be the go for placement. it would only measure say 1-2mm max deflection.. I am just assuming here tho. lol

for a solid mounted wing... perhaps the boot latch?

I would like to know how that works Walter. My wing will be welded to the chassis, so no putting load cells under a mount as such.

The yard is clean- I just don't have any more room in the car garage, LOL. I could park in the entertainment area, but then where would my bar and BBQ go? I cant get to the sheds out the back due to some fences etc. I think I mentioned one of my sheds is an old stables- I have enough room to park about 10 cars if I wanted to use it for that. We lucked out buying this place...


Some pics for you Andrew. The mount I built last night is flawed. I inadvertently built a cantilever into it by having a single post down to that box section in the boot. So it you push down on one side of the wing, the mount acts as a pivot and allows the aluminium upright to move enough that it is visible. It'll have to come back out and be replaced by two posts done to the floor.

I have drilled the bumper to play around with a rear 'strut' which I have made from a 10mm steel rod. One end will be threaded and the other have an eyelet welded on. The purpose of this is to be able to stress the rear side of the mount to make small corrections after the welding at the front. The lever effect is so that 1mm change in the mount geometry could cause 5-10mm at the wing tip. I don't car how good you are, there is going to be some correction needed after welding that many joints. Better to plan for it.

My first idea was to weld two 30cm long bits of steel angle either side of the boot catch and reinforce that with struts to the floor. I baulked because of the amount of steel I was adding to the car. It might come back to that as the mounts need to be sturdy and very, very rigid. The original West car has these mounts bolted to the gearbox.

welded mounts to chassis... i dont think it can be done, unless you utilize your cantilever creation :-)

if you were to mount the wing as per your pic, u would have to use pins instead of bolting it to the bracket, so it can swing. mount the load cells under the wing mounts, where it rides over the boot. pivoting off the pins and applying force onto the load cells then to the car. modify your bracket and wing mount so that they have stoppers, to stop the wing and mount swinging forward when under heavy braking (at low speed)and swap those external mounting rods for boot gas struts?? a little bit out of the box lol

a pro would be that it's a direct load and direct readings. a con would be the direct load is not on your chassis....or is it??

Cut the bottom half off those mounts, and attach new ones directly to that box section from the rear (look at the pictures below - on the Soarer you go in through the rear bumper, the boot is too high).

Then you can either weld your current mounts to the new ones, or drill and bolt them together, which will allow for angle adjustment if you want it.

Note also the horizontal stays between the mounts, which provide rigidity to help stop the wing wobbling you were concerned about.

Yep. Got it. I might see how much it will cost to get some mounts cut from 5mm thick ally plate so they go right down to the steel box section. Less joins equals more rigidity. Then I could just weld some brackets etc off that box section for it to mount to.

Guess I need to mock up a template and have a play.

No hurry. I have run out of cash and 'man points' so I need to focus on the house and family for a while. The downside to having a big property...

Ben also check out some of the wing mounts in this link
