CP's Trackday 1.6 on TB's re-build

Craig - I'm reserving judgement as well! lol It maybe that Oli is right- this plan is only at the "lets make something, bolt it on and see what happens" stage. I'm not too worried as this isnt a road car so it doesn't really matter if its goes tits up. I'm reasonably confident plus if you picked up one of those arms you would realise that its not going to be wearing out or breaking all that fast (its all abit OTT in spec plus those are caterpillar bolts;) )

Chimp007 - Sounds interesting. When I get it sorted i'll get back to you on that cheers:)

On the annoying front you may see that 2 rusty holes have appeared:mad:
The next stage is the installation of a homemade extension to the roll cage.

Yep Dave -its in my workshop. I go down and sleep with it every night:D

I have some issues to sort with it. One is the location of oil reservoir and the other is the (what I consider to be pissy****d but maybe the correct one)drive belt and crank pulley for the oil pump. Quite honestly I wouldn't trust it to power a windscreen wiper let alone something as important as the oil pump in an engine thats dry sumped and revs its nuts off.

Today I've been getting ready to extend the roll cage and strengthen it somewhat. First job was to remove the windscreen and the drivers seat. Next I made holes through the bulkhead with a hole cutter and a modded driver

yer wishbone affair looks very akin to the way the ones on the VX are done... esp with the castor adjustment via shims lark too :D cunning plan.

My mate has seen a catbolt go through a gearbox from a rugged terrain loader........ it came out with a few dinks but the gearbox had no teeth left on the sprockets :D

lol

hi cp
long time no see! have been reading your thread with interest after i was linked to it, the new engine looks great! much more cost effective than the 1800

anyways, a couple of things, the belt supplied with the dry sump is correct, but you can get one that is double the width if you are worried, not seen one fall off ever though
and on the subject of rose joints, pushing/pulling on them in the orientation you have described in this thread is what they are designed to do, and most have a spec with them for maximum static and radial loadings, as an expample, a 3/8 x 1/2 inch rose joint of decent quality has a ststic loading capability of 45,000 psi, you really wont push the ball out of the socket as it were, race teams even use them as top mount bearings
like your wishbone, but i wouldnt want to load a bolt like that, even if it doesnt break, it will wear, putting phantom loadings into your suspension where you least want it
not at all having a dig though, i had to re design my tie bar setup after i discovered a fairly basic major design flaw!!lol sorted now but thats what playing with your car is all about right?
anyways, looking good mate, have to catch up at a show sometime this year:thumb:

Hi Lee,

Good to hear from you and thanx for all your advice about 1800's :) .

Must admit I'm pretty ignorant about the subject of rose joints - the ones I have fitted were scrounged of a crop sprayer!lol
Anyways I'll try what i've done and see how it goes - its not a major job to convert them. Hopefully being as I dont have a heap of torque or a lot of weight there wont be a breakage.

You're right about the belt as well - i checked on SBD - i think i'll take everyones word about itlol

carried on with extending the roll cage and building the turrets up.

Seeing as all the old timers are coming out of the woodwork in this thread... hello!! ;)

Looks good C! Sad to see the 1400 go pop but onwards and upwards I guess :D

Hi:) It was only a matter of time with my old engine seeing as it was always driven absolutely flat out on track with no mercy at all - TBH I was chuffed it lasted as long as it did.
Hope you are keeping well and perhaps catch up with sometime this summer?

Cheers mate:thumb:

no worries on the 1800 advice mate, hth:thumb: look forward to seing this all together again:)

Hi Lee,

I would like to second the thanks on the 1800 advice, bit rude of me no to get back to you. Your build looks pretty special too, long ay on from the old days when we met in MK and our first corner experience at Silverstone!

Back to topic, and I'm just jealous that I don't spend as much time as the lads at the farm working on the car/s.

Oh and Breeny, I believe that you have contibuted to this latest rebuild!

Wahey! What random part has found a use then?

C - Yeh meet up in the summer sounds like a good idea! :)

Top Job. Not entirely how I was expecting them to come out but nicely done.

Looked pretty tragic when just the lids were chopped off.

no worries mate, just figured you'd decided not to go that route, it is still a bit new to be the first option for a small block yet, should be interesting to see the results, but i wont call it special till it makes the numberslol

These pics show the extended rollcage pieces being welded in

A couple of pics of my bro's bargain track day basher. Ex race car - fully caged, plumbed in fire extinguisher, bucket seats, harnesses, decent Ohlin (I think) suspension etc etc ....was bought for the princely sum of ?2500. Cheap as chipslol Incidently dont be tempted to add those trumpet socks - they can lose you massive horsepower!

blimey CP - those strut tops are brilliant!

Dont suppose you know the mod to adjust the camber on a 60mm drop do you! (seem to recall the "file the hub" mod and something about moving the strut top bolts by 7mm outwards???)

The beemer is fantastic - I always wanted one in that old shark nose style -

that beemer is lush. loving the triangulation aswell

Ade, I cant remember the exact details but what you said sounds right to me for getting the camber sorted something more appropriate for normal tyre wear and road use. TBH i would try those measurements and then if you have a good eye for whats straight and square you'll be able to ge a very good idea just by getting down low and looking at the front wheels from the front of the car when its parked on level ground. That'll get you ball park and you can then take some measurements to fine tune it more accurately

the novaload mod was to redrill/slot the top holes 1mm per 10mm of drop (moving the holes outwards to correct the neggy camber of lowering)

then weld washers ontop to stop it from moving.

Yeah, I found doing up the top mount bolts extra tight with serated washers didnt help. Welded in washers are quite necessary.

Loving the work Charles! Really good to see some new ideas about!


Nice Beemer aswell...Got something very similar up my workshop, although tripple webbers instead of TB's...

:thumb:.

All but finished the additions to the existing rolle cage. Got the side bars to go in still but once they are in I'll feel a whole lot safer:)

moving on very quickly! looks good

Nice work on the cage :)

Overall some really good fabrication work there.

I was concerned when I first saw the turret tops being cut but now they look fantastic. Hats off to you CP!

Managed to get some time to have a go at my car again. Main jobs today were to sort out where the dry sump oil resevoir should sit and drill a hole for the feed from the tank to the bottom of the pump.

Whilst I was working in the area I needed to sort a hole for the gear lever arrangement which will go direct to the selector housing quaife style but in a straighter line requiring fewer U/J's. From my experience with doing similar mods, the steering rack tends to be in the way so I took the opportunity to move the steering rack mounting points upwards by cutting them out and re- welding them about 25 mm higher up. I was keen to do this cos my steering arms have been angled too far upwards for my liking since I lowered the car as much as I could to keep the centre of balance as low as possible.
I also elongated the hole for the steering wheel shaft.

What on earth have you done to your brake pedal? lol

Great skills as normal Charlie :)

lol I noticed that as well and thought WTF and then realised its the throttle pedal which has been removed to allow for stitch welding:D

Had a bit of time spare today to look at sorting out a home made gear lever mechanism. Wasn't sure what to use as the main bearings/bushes for the connector bar from the lever assembly, thru the bulkhead into the engine bay. The bar has to move backwards and forwards as well as twist. Eventually I hit upon the idea of chopping up old shock absorbers and using them:
http://i205.photobucket.com/albums/b...a/24307001.jpg
From the debris I extracted the top seal and bush which go together on the shaft like so
http://i205.photobucket.com/albums/b...a/24307002.jpg
http://i205.photobucket.com/albums/b...a/24307003.jpg

Next I offered the whole lot upto the hole in the bulkhead to see how it came together
http://i205.photobucket.com/albums/b...a/24307004.jpg
http://i205.photobucket.com/albums/b...a/24307005.jpg

With a bit of modding this will be welded in place at the the right angle to allow the shaft to be able to move in the correct alignment. If you compare pictures you can now see the value of moving the steering rack up

Some great ideas! Loving the rack re-location!

Finally I had a go at making the gear lever assembly. Its not exactly going to be light but I haven't had to buy any new stuff so if I can get it to work ok I will have save shed loads of dosh. I've utilised another shocker and this time cut the main shaft and welded it together side by side to get the necessary offset. I've used the seal and bush in a similar manner to the previous pics so that when installed there will be 2 of these guides for the gear shaft to be located in. The gear lever rose joint assembly is one of my old tie bar mounts that I no longer need.

Top work.
Lol @ chopping up a shock to make a gear linkage.

..NOW I AM IMPRESSED!

Grass roots modification at its best.

just read the whole thread, some very impressive ideas

intresting
