Thanks a lot Colin.Incredible skill, knowledge, time and patience to create this monster!! Lovely write up and who doesn't love freshly painted or custom engineered parts being fitted. Top work.
Cheers Jamie.What a great build. Some lovely attention to detail.
How did you find the HPA wiring course was thinking about it myself as want to build a loom for my PH1 race car. Maybe this year of season doesn’t start soon!
Thanks.Great project. How do you find the Proform scales? I'd heard they weren't the most accurate but I've not tried them myself, as you say the cost of these vs others is a big gap.
Also the Corvette brake ducts are a brilliant addition, would you be offended if I blatantly copied that idea on my own car?
Cheers Jon. Glad you’re pleased with the uprights.Looking good fellas. Oh and those hubs and bearings are working lovely on the daily 👌
Can’t remember off the top of my head. Will make a note of it when I next measure it.How much camber is on each wheel when you turn one way?
Thanks for that. Think I will change to a bit of toe in at the front to start with to be on the safe side and then have a play from there.I went for 6 mins toe in per side and 2⁰ camber, im gonna probably push the camber up some more as it still wears really hard on the outer edge of the tyre (this is on cup shocks and Cooksports so ideally need coilovers)
As for the rear toe, try and slacken the beam and move it around as there's a lot of adjustment to be had from them just from the bolt holes alone
Hi fred what pieces did you use for the u bend ? I need to do the same to bypassPost number 11.
Been too long since doing a post but been busy with the car at least. Had the engine running last weekend so need to update the last months work so I can do the start up post, only had a few problems.
Next job was to get the engine in but decided to add some DEI reflective heat shield to the tunnel before I did so. Nice easy job which made a change.

Hopefully this will be the final time putting the engine in before the car is running, got the knack of getting the engine in and out now, just need to get engine tilted in the right way and it’s a doddle, having the right kit does also help a lot.

Coolant hoses worked a treat. Used a standard 182 set from MTC and to bypass the heater matrix used a u bend piece. Even with the different radiator and orientation the hoses worked pretty much perfectly. My plan is to have an aluminium coolant tank and catch can but the standard one will do for the time being.

I have already done the fuel hard lines so needed to sort the tank and rail flexi lines. I decided to get Atec to crimp the OEM fittings to their dash 6 400 series hose. So sent Atec the hoses cut to length and the OEM fittings, they came back perfect so glad I did it.
View attachment 1492897
Since I had the flexi lines back meant I could fit the fuel tank, so added some more reflective heat shield material for where the exhaust gets close and got the tank in. Fuel hose worked perfectly with the right angled fitting from the tank, hose coils round and then used a 30 degree fitting to the bulkhead fitting of the hardline.

Same as the fuel lines, the brake hard lines had been done but needed to do the flexi lines. The Atec fittings and 600 series hose are really nice and relatively straight forward to do. Just make sure to buy the mandrel tool, made splaying the braided part of the hose away from the inner tube nice and easy. Used stainless steel adaptors to convert the an-3 hose fitting to M10x1.0 calliper.

Was then getting very close to getting some electrics in the car.
I went for 6 mins toe in per side and 2⁰ camber, im gonna probably push the camber up some more as it still wears really hard on the outer edge of the tyre (this is on cup shocks and Cooksports so ideally need coilovers)

Post number 20.
Alignment and corner weighting.
Should be a shorter post this time as I’m up to date with the posts, this is the work I did over Easter weekend.
I showed the scale pads I made in the last post and was keen to give them a go. Started setting them out and adjusting the height with the 6 feet on each pad with the help of a spirit level and laser level which I had previously used for measuring the roll cage.
View attachment 1531485
To make it easier to get the car onto the pads I spray painted round each of the feet to mark the position so I could move them out the way, roll the car back into the garage and then jack the car up side by side and place the pad back into position.
View attachment 1531489
First I was keen to see how well the turn/slip plates work. I polished the surface and used PTFE lube on both sides of the PTFE sheet (shown in the previous post). Got the car on and could instantly tell they where working as the plates moved out slightly as the suspension settled. Sure enough turning the wheel was very easy too.
View attachment 1531491
View attachment 1531492
Not sure the video does it justice but will just have to take my word for it that there is hardly any resistance. Can easily turn the wheel by turning the tyre itself. And can actually shift the entire car side to side by giving the wheel (not steering wheel) a sharp yanked. So I was pleased with how they turned out, and a bargain compared to the price of proper levelling pads and turn/slip plates.
View attachment 1531493
So the first weigh and the car was 962.5kg (just noticed now that is minus bumper) And the corner weight was a fair way off bearing in mind thats minus driver.
View attachment 1531494
I checked castor before doing the corner weight and needed to add a fair amount. Please feel free to comment as I am no expert on alignment setup, but from some reading I was aiming for a few degrees of camber and around 8 degrees of castor. Is this the right way to go? No idea but it seems sensible to start with. I didn’t get a picture of it but bought a used longarce camber/castor gauge. Had to turn the wheels 15 degrees to measure the castor which was a bit of guess work so need to think of a way to measure the steering angle accurately but for the moment it will be fine as it should be similar left to right.
So after some playing with the front left and rear right ride height I got the corner weight to 50.2% with myself sitting to the car. Now what I am unsure about is how much of a difference the side to side weight distribution makes? 53.7% vs 46.3% of the left.

I had made a couple of fixtures to hold the string alignment poles a couple months back (in a previous post) which attach directly to the car which makes it nice and easy whilst jacking the car up to make adjustments. Some brick line off Amazon for a couple of quid with some bolts attached to the other ends did the job for the string itself.

I maxed out the front adjustment for camber and adjusted the steering arms. And these are the numbers i finished up with. The camber numbers are obviously negative too. Front toe slightly different based on having the steering wheel straight. Obviously will need a little play after the first drive.
View attachment 1531499
So the rear needs some work. I worked out that 1mm of toe is equivalent to 0.132 degrees, so to get the right hand side as close to neutral as possible I would need a 0.73 degree shim (obviously doesnt exist) so to the closest 10 minutes is 40 minutes to have slight toe in or 50 minutes for slight toe out. Does this sound about right to you or have I cocked something up here? And for the left hand side with the same logic would be 10 minute shim for slight toe in or 20 minute shim for slight toe out.
Would be interested in peoples own experience with their setups. Keep in mind this is purely for track use.
Haven’t got an awful lot left to do now. Mapping is booked in with RRR Engineering for May so not too much longer left until it will be up and running.
Used a set of the MTC hoses then cut the one from the heat matrix in half.Hi fred what pieces did you use for the u bend ? I need to do the same to bypass
Cheers Rob.Finding it a bit hard to believe your rear right toe.
But either way - I've dyno'd a number of track/race cars in the past and they are a dick head for walking all over the rollers due to wild tracking and or camber so you end up strapping them down harder than is ideal. For the tune I would suggest you run close to standard figures and scrap/hard tyres then switch to track geo setup and tyres after. Like maybe just go for 0 toe 1 deg camber for the dyno....
Nice setup too, your plates looks great!
And also.... how the hell did you discover those Corvette brake ducts? Look absolutely perfect for the job!
Cheers Rob.
It does seem a fair way off doesn’t it. But I have hacked the rear beam to bits and welded the stiffener kit on so would have put a fair bit of heat into it, plus if i can even the toe up left to right with a bit of a wiggle of the body mounts like @Yorkshire Pudding said then it would make more sense.
Someone please correct me if I am wrong but I believe the dyno RRR have is a hub mounted one so assuming won’t have issues due to the alignment?
Haha, saw someone using them in Australia or New Zealand, can‘t remember which, on a gt86 build thought they looked like a decent option assuming the size was about right so decided to take a complete punt on them and paid off.
Thank you very much!Wonderful talent and fantastic attention to detail.
Did you buy the Z06 ducts over here or did you buy direct from the US? Also may i ash what you have used to connect them to the foglight apertures. I think id like to do the same, providing you have no tyre fouling on full lock.
Thank you
Thank you very much!
Bought them in the USA on eBay. This is the link to the ones we bought.
https://www.ebay.co.uk/itm/281605705202
At the moment I haven’t done anything to attached them, I have made the bumper quick release so I am not keen on having them attached to the bumper really if I can avoid it. I bought a set of 3D printed ducts which clip into the fog light holes which are meant for a hose to attached to but the corvette ducts are pretty much a tight fit up against the back of the fog lights so not sure it needs anything yet. Only time will tell when I get it on track. If it does need to be attached somewhere then I plan on making a bit of a bracket off the front bumper beam to fix them in place better.
So with my setup at the moment there is no fouling at full lock. That’s no spacer but Laguna uprights, the Laguna uprights I believe give a slight track width increase so assuming it would be the same as standard upright with a small spacer. But there seems to be plenty of room.
Thanks for that, im running the Northloop RCK hubs and only a 5mm spacer up front so should be okay for lock.
I thought buying direct from Uncle Sam might be the case, i'll just get bummed for soem VAT & duty lol
Completely agree. The global eBay system works a treat. Bought a few things from the usa through eBay recently and haven’t had any bother.Sorry to butt in, but if it helps, I ordered those ones above and the EBay Global Shipping Program gives a total shipped price inclusive of duties etc. Streamlines the process a bit and stops any nasty surprises on arrival.
Edited because the link doesn't need posting twice lol
Need to copy this intake set up , looks good fred. Whats the details on the carbon box ?Post Number 18 continued.
Since the wiring seemed like it was all working ok it was time to give the wiring a tidy up inside. Used braided sleeve for a lot of the wiring on the bulkhead so it would be nice and easy to add or modify any of the wiring at a later date.

The wiring on the bulkhead isn’t as tidy as I would have liked it to be but functional is better than it just looking tidy I suppose. Hopefully it won’t be noticed once driving. Seems to be hidden a bit more from the drivers eye.

Added the cage padding and checked on head room with my helmet on. Very close but just about manageable. Can gain 5mm with different seat bars, MSA/FIA says 35mm seat rails are ok but I ended up using 40mm so that could gain some room. Can move the seat down one notch on the side mounts too. The plan is for me to remove the seat cushion to drive and James can add the cushion in which will give us the different driving positions we need. May look at a resin seat bag instead of just the cushion difference if needed.

Air intake was next. Thought of the different options for this but kept coming back to the same design as what Scott has done on his car (tomtek / pro-am racing) so I am afraid this is just a copy of what they have done. Revotec intake duct, ASH hoses and a carbon filter air box. Gives the best combination of ram air feed and cold air feed. Added stainless hose clamps and seems solid even without a mount for the carbon air box.

I gave the inside a good clean when tidying the wiring up, so finally decided to buy a car cover, Halfords outdoor car cover for £40. Extra small and fits the Clio perfectly.

Nice!Need to copy this intake set up , looks good fred. Whats the details on the carbon box ? View attachment 1531517
Not yet fred , i just couldnt see any detail on that. Assuming the other bits are available online ?Nice!
Its one of these:

Assuming you’ve got the rest of the other bits sorted?
Yes, got the ASH hoses on eBay and revotec duct from eBay too I think.Not yet fred , i just couldnt see any detail on that. Assuming the other bits are available online ?
They look like the ash ones i did have in blue which i sold apart from they were 2 90 degrees. Will get them ordered with the 180 i need. Thanks for info fred , thats one hell of a clio build !Yes, got the ASH hoses on eBay and revotec duct from eBay too I think.
Not a problem. Cheers mate.They look like the ash ones i did have in blue which i sold apart from they were 2 90 degrees. Will get them ordered with the 180 i need. Thanks for info fred , thats one hell of a clio build !
It will depend on whats been setup on the bump steer adjustment. A bit of toe out is more desirable on dive as you probably wont be able to get zero bump steer.Are you sure your toe in at the front? These should be toe out front. Under braking or as the front dives they will go more tow in I think....
