Postby trublustu » Thu Aug 17, 2017 9:56 pm

I`ve not updated the thread for a few weeks,
and what an eventful time I`ve had...

Firstly, the seat and steering wheel position got attention.
I have the seat perfect for my long legs, but the steering wheel is miles away!
I thought a deeper dish steering wheel would be an easy answer. But how deep?
I could spend £50-£100 plus on a wheel, only to find it`s not quite right. Which would be a sickener.
So I picked up an universal adjustable spacer for less than twenty quid to find out first.

5856

I removed it almost straight away. The wheel is noticeably higher, and with the seat being lower driving was awful...
The seat position itself, is miles better though

5857

Slightly lower but an inch or two further back.
I`m going to look at altering the angle of the steering column to drop the wheel before fitting a deeper wheel.

Also, my car came with a home made `FRP modded` airbox.
It had seen much better days.
I decided to replace this with a `Mk 2 ` version
Taking a decent airbox I broke out the saw and cut down the bottom of the airbox. patching it with some more numberplate.
The cold air feed I directed directly into the front of the airbox raher than at 45` like the FRP.
I then made (tried to) an angled trumpet for the headlight.
This should give me a `ram air` feed at speed.
That`s the idea, here`s the photo`s,,,

5853
5852
5854
5855
5851

And so to the next sprint round at the Blyton Eastern.
As usual for Blyton, It rained in the afternoon..
Still, I managed to punch well above my weight, winning my class again and finishing 58th overall.
I beat all my group too, but with the sprinkling of Evo`s that showed up, I knew points would be hard to come by.
I managed to catch my splitter on the trailer while loading up. So a quick repair was needed to compete, with a more durable job done back at base.

5858
5859
5860
5861

Next stop Fordfair.
Now that`s another (equally long) post...

So, to bring things up to date...

Firstly, I broke out the Autoglym, fitted some suitable tyres and headed to Fordfair.
Thanks to the huge queues and sneaky campsite entrance i actually found myself on the stand quite early so got time to actually take in some of the show. Good to meet and re-meet a few of the pp members.

5869

The makeshift bonnet strut got some comments!
I`d booked a couple of afternoon tracktime sessions and had a great hoon.
Being an experienced track driver, on decent tyres in a set up car, It`s easy to look like a driving god at Fordfair.
A few cars gave me a scrap, This guy gave me the race of the day (I came out on top)

5870

It`s ashame I had no dashcam I passed the entire field in my second session. (I went out second last because I was carried away chatting and realised I was less than five minutes till my session... and mid ice cream!)
This vid is from a pro modified Focus 225 that went out behind the pace car..
and I pass him on 19 minutes.

https://www.youtube.com/watch?v=2S4v0UPjqIA

Bang on cue for my third engine to explode.. :teary:
Right in front of the camera!
As I passed him I felt a knock (you see the car kick) then another, and so on, until.. it turned into a box of nuts and bolts.
As he starts to pull up on me, the car is visibly shaking!
I limped it home and looked forward to having an engine to swap in two weeks before my Angelsey Sprint!

Great :roll:

I had originally had an epic week of sprinting and trackdaying planned, taking in Curborough and Angelsey.
That obviously, went out of the window!
But I did still have a week off work.
..And a well maintained donor engine.
....And the weather gods smiled :grin:
......And... Just to make my bank managers` blood boil, a chap popped up on facebook selling a lightened flywheel
So I reached deep into my overdraft and shelled out on this.

5871

Like everyone, Iv`e heard horror stories regarding these machined flywheels exploding!
But as it has been used (hard) in a rally car, I`ll take my chances that it`s a good `un.
So..
day 1. Identify problems and acilliaries off
day 2. Engine out and stripped
Day 3. `New` engine cleaned built up and `breathed on` (flywheel arrives)
Day 4. Engine in and start, second turn of the key (forgot the engine earths)
day 5. Eat, bathe and sleep...
day 6. Take car to Angelsey for my rebuilds baptism of fire..

As I have done this several times over, I didn`t bother with a photo story.
One thing I did do differently, was be utterly fastidious in my work.
Check, check and check again. Everything..
And boy is it clean inside that engine bay now!

So, onto day 7...

5868

The car felt quite different.
The power delivery felt smoother. but stronger.
Possibly down to cam timing being absolutely spot on.
I found when building the engine that it took a couple of attenpts to get it precisely right.
Last time I was pushed for time and I doubt it was a close as this.
A 33% lighter flywheel no doubt helps too!
Most cars were setting similar times to last year (all slightly quicker, a few standing still)
I utterly smashed my time from last year. :D
Setting a 1:49.49 Down three & 1/4 seconds from last years 1:52.75
My careful rebuild, flywheel, FRP LSD box, LMS plenum and proper sprint tyres probably cost the best part of £1275 but have given improvements in results on par with guys with 10k engine builds.

Feeling Smug

A stiff gearchange meant dropping to second for the slower corners meant it was more trouble than it was worth.
The video below is my last and fastest run. Hitting my target (sub 1.50) with the last run of the day. 1.49.49
I take two corners in third when really i needed second.
Oh boy the engine tone changes when you drop of the power!
I really need to look at that..

https://www.youtube.com/watch?v=Kl9-sz-ERic

5867

I am really pleased that the engine didn`t skip a beat. not a spot of oil or loose bolt.
Needless to say, I am smashing the championship class too ;-)

5866

I`m not sure whether I heard a wheel bearing squeaking while creeping forward in the queue.
But that is ongoing maintainence.
Though I might just make some changes here, I`ll think about it..

So....

I should pull my finger out and update things.
So I`ll bring us up too date..

All has been rosy with the car, The post outing checkdown revealed nothing requiring attention, So I rubbed my hands together and readied myself for the final sprint of the season well in the lead in my class.
Not quite out of reach, but It`d take a disaster to not clinch the class win..

The week before Cadwell, the Trackheads group organised a rolling road day.
Now when I`d reassembled the engine, I had been relly tight with all my tolerances and settings.
With the new flywheel I hoped for a couple of extra ponies.
And I got them :grin:

5899

Very happy with 140.3 bph at the flywheel.
That`s 4.5 brake more.
Just for being precise in my work (I was rushed with an untested engine last time)
The car had felt stronger at Angelsey. :-)

So he car stayed on the trailer and rolled off at Cadwelll Park a week later.

5900

a real treat was that there were 3 other trackday Puma`s there too.
Some competition!!
Under leaden skies on a rather cold late October morning I really focussed on not binning it, as I teetered my way round the very treacherous circuit.
Very, very slowly a sort of line as appearing through the drizzle and leaves.
I was having to scrap for the gong this time..

Then at about half three an EVO managed to self destruct on the final straight (bottom end exploded) stopping proceedings.
There was about 40 minutes waiting while they cleaned up and cement dusted the oil slick.
The gods of motorsport chose to smile in that 40 minutes,
the clouds parted a little and the wind almost finished off the track drying and we had one final run,
on an pretty much dry track.

Driving like it was the last lap of a grand prix I set my best time of the day, winning the class by 2 clear seconds.
Championship win and 5 wins out of 6 along the way.

5903
5902

I also made utter mincemeat of the othe Pumas, although I have been sprinting for a couple of years and these guys were new to it.
Big happiness and absolute faith that the car works exactly as it should.

I`ve been very modest about my win, which is why I`ve not told the tale for 2 1/2 months
I`m not a self promting type and didn`t want to turn the thread into the Stu Show!

And that was that for 2017.. or so I thought...


I have wondered just why my fastidious build with FRP spec throughout is 15bhp down on a standard FRP!
I was talking to Erroll and he asked about my cars loom (It`s a twin lambda loom)
It turns out that a without a small modification the car runs assuming it`s on 91 ron fuel!
So Erroll very kindly sent me a replacement ecu and I booked onto a trackday at Oulton Park in December to actually swap the ecu and `Pepsi challenge` the modification.
I had a video on board and the modded ecu made one hell of a difference.
Here`s a couple of short vids from late in the day

https://www.youtube.com/watch?v=JpQwIp3TfKs
https://www.youtube.com/watch?v=eryR8jbjhOI

My mate with the Clio said that after the ecu swap he was having to work hard to catch me....
Timing clear laps off the dashcam told me I was two seconds quicker.
I`ll take the car back to Tuning Developments for a dyno run to see whether I`ve `found` the `missing` 15bhp...

One last pic for the year, Nailing the apex at Lodge.
More plans for 2018..

Cheers Barry.
Next season my class has been tweeked. 1600 to 1800 this time.
I'll be waving the puma flag against some quicker cars this time.

As for the surprise power boost, I need to throw it onto the rollers to prove the difference.
But it's there
Handy as ill need to up my game to be competitive..

Well we are now out of January and it`s about time to start thinking of where to take the track car this year and what further improvements I can make on the car.
I really am happy with the cars performance, as seen by the times on the final sprint with the other Pumas there ,
the car is streets ahead of a regular track day Puma.

So it`s time to look at the small stuff.
While, post trackday checking following the Oulton outing in December, I found that the gear linkage bolts werre not tight. "that might explain my struggling a tad with the box" were my thoughts..

Once I`d tightened it up I realised that there is a quite floppy bush between the bracket and linkage, and there was significant movement when moving the gearstick.

So as my first little play of 2018 I have broken out the hot glue gun and packed a spare buh (I had lying around!) full of a couple of sticks of the stuff.

5911

When set the glue is nearly as stiff as a cheap polybush
If There`s a noticeable improvement in gear selection, when testing on track,
i`ll invest in some pukka shore 85 polyurethane resin and make a more robust one.

My other thoughts are turning to aero.
The last outing at Oulton was without any splitter at all.
In slippy conditions I was not as sure footed as usual, so that will be getting seen to.
I`ve also started putting together a diffuser. and maybe a little more too..
I`ll stick some photo`s up shortly

Whit a genuine headache to deal with...

As for what to do this year, I`m going to compete in the Javelin Trackday Sprint Series again (I got a title to defend)
I`ll probably be limiting the trackdays to an early test day and end of year get together with the sprint guys.
I have plenty of space for cars, but no garage, and that needs my attentions and money atm...

I will of course be at Fordfair in the summer
And a week later I`m visiting a place called The Mid Wales Activity center.
They have a driving circuit over 2 miles long which is more like a rally stage than a circut..

Should be just a little fun..

hey stu good work with all the racing!

thought there was a solid mount for the gear selector isn't it available through pumaspeed or similar?

Instead of a hot glue, use a windscreen glue (Sika is the best, https://www.google.hr/search?q=sika+tac ... 79&bih=649). Just look at some repair shop, they never use the complete can and some is left in it. For your purposes more than enough. It is excellent stuff; stiffens rubber mount very nicely,sticks just about to ANYTHING, but still allows for some play. I am affraid that this hot glue, which is now completely solid will start cracking and falling down.
I would also advise you to start stiffening progresively. First just one line of the stuf, and then see how it goes. IF it is not enough, add another layer (by using the handgun) etc. You might still want some play in it, not solid connection, as the gearbox might get hurt; I suppose your engine and gearbox mounts are much stiffer than they used to be, so you have to allow for some play somewhere in the system

I have seen those steel brackets Sleeman, I`d just never seen just how much play there is in the standard unit.
At £40 for the pumaspeed one, I`ll see if my home made bodge makes any difference before thinking of shelling out.

Good shout with the Windscreen glue.
The hot glue doesn't set hard, probably similar in consistency to windscreen glue and I cant see it being fitted long term so cracking shouldnt be an issue.
The linkage is still free to move back and forth freely so I`m confident it wont shake it`self to bits either.

As I say this is a trial, I`ll be taking a spare standard bush with me when it is tested, just in case it doesn`t work.

Thanks for the feedback guys

I know people are using this technique to stiffen engine mounts with great success and no problems with it whatsoever so that might be of use in long term as well. It is for sure cheaper than anything you would have to buy and is scalable, so to speak

I have a Vibra Technics lower gearbox mount, which I came across second hand.
£145 new would be way too much to spend on a seemingly minor mod.
But it certainly made a big difference on the car.
At the moment the upper mounts are the stiffest standard (used) ones I could find.
With the rock solid lower mount the engine is surprisingly stiff in the bay.
That lower mount (torque link) seems to be where most of the engine movement comes from.

I`ll find a suitable product and stiffen both this small bush and the upper engine mounts too.

The mount which the gearbox hangs from is notorious for changing shape because it has gaps both from the upper and the down area. This has as a result the gearbox fouling the lower strut brace. These gaps could do with a bit of windscreen glue.
