I agree completely as I don't want the car to be to low for no reason. YOu need some suspension travel to follow the road as it is.
That look of the rear wheels would suggest 30 mm spacers with drum brakes....

Thanks for the info

Rears have 10mm spacers and disc conversion.
I am thinking of getting rid of the spacers to induce just a little oversteer.

Strange, I have 20mm spacers on the rear and it is extremely tail happy, even if you only tug the wheel left or right. The only way I can get understeer is in damp conditions in 2nd gear and floor it mid corner. Coilovers are as low as they can go and it has literally no suspension, fine on the track, not fine anywhere else.

I will take a photo of the "Stance" so you can see if there is more or less weight on the front/rear if it helps you.

For the little time I had on track last I found losing the backend a lot of fun and really quite controllable (running AP's lowered 50mm, oem rear bushes, rear arb, rear omp brace and 12.5mm spacers)

It was a fantastic day, Stewart is a wonderful driver and the Puma a great car.

And as for the 'off' I wouldn't have missed it for the world :) A complete track day experience :shock:

You got that alright Yvonne..
Although the camping in a van on the other side of the country, is the cherry on top.

And at no point did the car explode it`s engine etc..

Great video Stu, looked like you were one of the fastest in the corners. With that said I reckon with 200hp it would make the Puma one hell of a track car.

Cheers, It`s in the corners where you have to make it count with just 1679cc`s
With the FRP cams in it, my car should work a whole lot better. (145 ish bhp)

200bhp would of course be awsome.
I recon that with just 170-180 you`d blitz all but the five figure mega cars..

Assuming you can paddle it..

With but a week untill the first Javelin Sprint Series meeting of the year I figured I better get on with sorting the last few gremlins and getting a couple of jobs finished.

Today I got underneath and had the first proper look since my attempt at joining the Cheshire farming set..

5576

It was absolutely filthy.
There was mud packed into every orifice at the front of the car.
It had dried like mortar and had to be dug out with a screwdriver.
There were clumps on every protrusion from the strut brace to the petrol tank.

Fortunately my makeshift splitter had protected the mechanicals which was a relief.
Though it didn`t survive, nor did the bumper `tags` it fastened on to to I`ll be replacing the bumper and replacing the splitter.

Apart from that, crash damage was negligible.

Giving me chance to get on with the stuff thats been bugging me.
Tickover first.
Now I`ve taken advice from a few people and with all the usual faults checked (air leaks, maf, tps etc) I had a look at my lambda.
unplugging it made no difference. Ah Ha! I though, looks like I may have something.
And indeed I did.
I found that the extension for the 4-2-1 was home made (badly)
and a wire had come out of the plug.

5583

There were crimp connectors under the tape and one of them had broken too.
It didn`t take long finding a plug and rewiring the extension.

When I first started it up the tickover was still racing (3k)
So I disconnected the battery and left it a good half hour to reset the ecu.
Starting it up, the tickover settled down to around 1200 (still high but loads better)
Resetting the ecu properly should sort it.

That was my Good Friday,
Three more days fettling the car,

Cams and seats tomorrow :-)

Today (Saturday) not quite as successful as Friday but I still got a few bits done.

At Silverstone and again at Oulton I had a quite noticeable issue.
I was seeping a little oil, not enough to leave spots but as it was directly onto my manifold, enough to smoke like |I was on fire whenever I pulled up.
Never gonna please the scrutineers that..
It took some finding as it really was a tiny leak, but i tracked it down to the driveshaft oil seal. (set in too far looking at the shiny driveshaft showing)
So i popped the OS driveshaft and replaced the offending seal. (fitting it to the correct depth)
All nice and easy as all the bolts have been off, cleaned and torqued recently.

Next up was the cams.
I`d forgotten just how bloody fiddly it is, with the engine in..
With the cams exposed, I set about finding tdc, not hard but the timing bar refused to fit in.
Just as I ran into this little headache, the heavens opened. Blowing straight over my shoulder into my open engine.
So i had to bail on that job `till tomorrow. If it`s dry...

So not as good as yesterday but still a good step of the way.

For tomorrow, if it`s dry, cams.
If it`s wet, seats/interior and bumper

Typical British weather! Good news on fixing the oil leak, I used to have an oil leak from the rocker cover onto my exhaust manifold. Was the worst smell I ever smelled ;p

I wonder what's worse, mud or gravel when off the track. I would guess mud does less damage but harder to clean off!

Sounds like you're making good progress anyhow Stu

And so onto Easter Sunday.
We are having real quality bank holiday weather, not quite the monsoon wthat hit yesterday, but 4 seasons in one day!
Fortunately the breaks in the rain/hail were sufficiently sunny to get my engine back together, with no more than a clean rocker cover fitted.
I did find the mud had got to my aux belt and some pulleys were cruddy.

5584

All cleaned before refitting
Started first turn of the key.

While the weather was harsh, I just got busy inside the car.
I recently acquired a pair of quite filthy, Cobra adjustable seats, on Cobra subframes.
I already have a pair of spongy 4x4 lightweight bucket seats.
I have been using standard (late) Puma seats and I am not a great fan of them.
They seem to encourage you to lean out of the seat. Giving a great driving experience, but not what I want on track.
I want to be almost held in by the seat.
The Cobra seats are in good nick and would be great with a clean, but the buckets get hold of you much, much better.

With the subframes weighing 7 1/2 kg and the Cobras weighing 15 kg this would be a heavier set-up than standard.
The buckets come in at 7.5 kg and win out. Two Cobra adjustables for sale.

5586

As the car is getting set up in `Sprint trim` only one seat is going in for now
This removes a further 23kg for the sprints

Another little task I undertook today was looking at replacing the upper grille with mesh.
Here`s the result (saves another 500g)

5585

I`ll be fitting a couple of LED D.R.L`s for poor conditions and painting the mesh and metalwork black.

As for Easter Monday, I`ll be finishing off my door card and cosmetics.
New bumper will get some attention too.
That`ll be fitted next Saturday before we set off.

It did just that. Wild.E
I`d noticed that the exhaust smelt really rich and started checking the fuelling as well as air flow.

Thanks for the messages, asking after the lip spoiler supplier.
My purchase history doesn`t go back far enough and that supplier I mention earlier is a duff link.
So I`m gonna have a good search later to try to find something suitable to recommend.

And so Bank Holiday Monday rolled around.
My job list still seemed impossibly long and I cracked on with gusto..

I`d decided to give the car fresh pads anyway, so hadnt inspected them since Oulton.
And I found one of my pads had the the least friction material left as I have ever seen.
5588
I recon If I`d finished my last lap I`d have ground metal..
as it is the back plate has barely touched the disc and hasn`t marked it (phew!)
So new pads all round and a pressure bleed just for good measure.

After staying away from any go-faster stickers, I`ve decided to give the car some character.
Mainly because it`s going to be very publicly competing in the sprints this year,
so I wanted to give the car some individuality.
Unfortunately I had to give in.
I`m no vehicle wrapper and the first couple of stickers I applied were so bad, I stopped before I cocked it all up.
I`ll be contacting a local guy to see if he has a spare half hour Saturday morning, to stick some go-faster stripes onto my car!

I also had a play with the front bumper. I removed the lower grill (another 550 grams) and with a bit of stretching I fitted some more of the mesh hat I fitted to replace the upper grille. It`s a full kilo of weight saving, better stone protection for the radiator and better airflow through it. win-win-win :-)

5589

I also spent a bit of time inside the car doing some simple cleaning.
There were nuts and bolts, grit, tools and other detritus everywhere.
No longer, all clean.
I also had a play with the seat position to get the right feel.
It`s totally different to the Puma seat and I`ll play with it a little more at Blyton..

Speaking of which.

My first attempt at an organised competition, the 2016 Javelin Sprint Series, starts next Sunday (3/4/16)
The first and second meets are at Blyton Park, near Gainsborough.
It`s the track I have driven the most and as the only Puma entering, I hope to fly the flag for the little Blue Oval

If anyone is free Sunday, you are welcome to pop along (it`s free) to offer moral support and hearty cheers..


p.s.
I`d better pull my finger out and buy/cut some plywood for my splitter
and get my soft tyres fitted to their rims..

No probs Barry, cheers.
I`ll be flagging up each event, it`d be great to see you at any of the meetings.

I may even write a dedicated Sprint Series thread, especially as i`m in the only puma taking part (so far)
