Bet you have itchy hands from cutting the carbon. ;-)

[turbotoaster]

will that not make a noticeable difference due to now being imbalanced?

 

Fitting a bias valve so should be ok, I know scuffers used to run 2 pots all around and was pretty successful on track, so it should be ok

[jules_s]

I would imagine Chris meant the hub being unbalanced?

[chris_uk]

Yes i did

[Zoobeef]

As above you'll need to notch the opposite side at least exactly the same.

[dewismotorsport]

That is gonna shake it's tits off now, hub material is no doubt 15mm thick and a chunk that big missing is going to fair few grams at a guess 20g so will drive like the wheel is out of balance

[turbotoaster]

yes I know about that, I will also taking the other side off, I just ran out of time today, I was more bothered about working out what spacers would work so I knew what length bolts to use incase I need to order some

 

I cant drive the car until i get new pads front and rear anyway so I wont be driving around with it unbalanced

Superglue the notch back on.

[chris_uk]

Couldnt you just of removed the hub, installed the bracket then put the hub back in?

[turbotoaster]

Nope, its a series 1 ali hub, so everything is pressed into each other, so you will potentially damage the wheelbearing, then if you do that you need to replace them and because they are fitting in a soft ali upright you risk wearing that out from constant wheelbearing changes, this way anytime I want to put the hand brake calipers back on i dont have to touch the hub.

Balance is going to be much less of an issue so close to the axis of rotation. Its still worth balancing it out though.

That's true but once you add a wheel to it, it will amplify it. Bit like when you have play in a wheel bearing, at the hub it only feels like 1/2mm but at the top and bottom of the wheel it's more like 5mm (example)

ok mini-update, all brakes are now on, new pads all around, loads of copper grease, bled all the air out of the system, under light load coming to junctions they squeal there brains out, but im guessing its because they need bedding in, just running pagid road pads for the moment as I have no plans on being last of the late brakers on the road, I have my PF01 for track use.

Painted the old red calipers a bright shade of blue and put them on the back to match my brand new calipers i put on the front


Fitted ready to bed in


I will put a bias valve on, will be having a leaver style version so its easier to mess with on track, going to get someone who can cut and fair brake line to do that though as its something I dont want to potentially bodge myself.

Also took my sump off so that I could fit the baffle plate system, scared myself silly reading all the threads of people killing engines, spoke to elise spares where I bought it from and they said never to weld it, none of there race cars have welded them and never had a failure from it, so decided to go that way.


With the expected lateral g force its something I will definately need, how much g I can pull before it stops working im not sure currently, dont really know at what point moving over to a dry sump is required.

Forgot to take a picture with the baffles in, ive got a magnetic sump plug which had a bit of very fine metal on which i cleaned off, shows its doing something.

Then because the weather was nice today took the car up the cat and fiddle pass up to the pub for a drink, was good fun and gave me chance to a bit of low speed mapping on the way.


A few people asked me about the car and I let a few of the children who came to have a look sit in the car aswell, they seem to enjoy it.

Popped up on my facebook feed yesterday someone spotted you. I could say it divided opinion but that might be an understatement

[turbotoaster]

got a link to it, always interesting to see what people say

Looks crazy matey

Got back on with sorting out the downforce on the front end, no point having a massive rear wing if you cant make use of it.

So first thing to was to put the canards back on, nice and simple.

Need to make some end plates up for the canards when I get chance.

While i had the front clam off I also cut most of the chin lip away so that the clam is easier to get on and off, which will be useful at the track.



Next its time to get all the high pressure air out of the from clam, so I got out the dremel and cut out the back near the door, I was tempted to cut it all out, basically from the top of the wheelarch just cut horizontally back but for the moment im going to just be conservative and get it on track and maybe do that next winter.


Next something ive been wanting to do for a while but ive been putting it as even I was a little bit apprehensive about cutting 2 massive holes in the top of my clam, in the end I just bit the bullet and made the first cut

Cut the hole out where i think will have the most benefit.


The issue you have with an s1 is there isnt a flat panel anywhere on the front and since the vents are all straight angles my concern was how to get them to fit neatly

Since I had 4 vents I used one as a test piece and basically hacked it up to remove anything I could see that would stop it bending to shape I wanted.

I fitted it and then marked and drilled the holes to bolt it down, the good thing with this is it showed me what needed to bend and be good on my best vents and also showed me what bits of the clam will flex to ensure its a nice fit.




As you can see ive cut the ends off as i was concerned it wouldnt bend side to side, but this left me with the rough edges of where i have cut into the clam which doesnt look pretty, but now I knew what i could and couldnt get away with.

So next I came to trial fitting my best ones with the modifications I had learned from my test piece



Here you can see how much they will vent, should be pretty effective, you can also see how I have got it to bend to the shape of the clam


My mate gives it the sign of approval


Im painting them black, in my kitchen drying overnight, so I will lacquer them tomorow night



As soon as the canard end plates are done I will start back on the rear wing pylons a few more weight saving ideas I have.

I take it you are not doing time attack at knockhill this weekend?

[turbotoaster]

No, I think the first round I will have the car ready for is cadwell, I plan to do that and also brands hatch.

When does the driver training start? Keep up the project updates!
