Were gonna have a hill climb contest for our annual mini meet next year but its just a fun contest. Everything will be safe and the organizers seem good st what they do and it looks like fun for a lot of us first timers. Thing is I want to try this and prepare but not sure where to start. Any tips on the engine and myself?

[Mk1cooper]

So far my car is in a decent shape structure wise. Engine is 1293cc, dual H4 carbs with float extensions, BG needles, 266 Kent cam and the head is a later cooper S ported and polished head but with stock rocker assembly, flywheel is lightened as well and exhaust is Works from Somerford with LCB manifold. Gearbox is a 4 synchro with straight cut gears and finalndrive of 2:76 i believe. Compression ratio is 10:1

Good tyres is what you want first and brakes.

A dogbox to with a diff ratio that suits the track.

Would it matter if i’m using the 10x4.5 steel cooper s wheels? My car is a works replica and planned on acquiring SP-44 Weathermaster tires for looks at first as it’s originally planned for car shows only but this time i want to participate in the hill climb. Wondering if this will work as well.

As Migliacars says if you want to do any good on a hillclimb....I assume you are on discs,  4.5 rims with 165 tyres, will be OK

maybe not the sp44's some Yokohama's would be better for the hill

You certainly need to bin the zero acceleration 2.76 diff and go for at least 3.76

I would also be going for a wilder cam

Depends how serious you are and your budget.

[MIGLIACARS]

Its a matter of how quick you want to go. If your happy trundling round at the back leave it as it is. If you want to be leading the pack, start spending!!!  AS above the power will come with a cam but with a cam you need the dogbox, dont bother with the sccr, If you want to go fast you will need to abuse it.

two comments.

 

what is a hillclimb to you?

read the rules.

 

then decide if you are there for the experience of to try and win.

 

and as an aside there is not much point doing any changes with that final drive ratio.

Sorry been busy at work. I do have another period correct 1522, 3 synchro A type gearbox that is like to install. This box also has SC/CR gears in it with a layshaft numbered 306. The ring and pinion included is a 3.76.

[Mk1cooper]

To be honest the hill climb contest is something i just want to try it out but won’t hurt to show up with something i can prepare in. If i like it then i don’t mind improving the motor with better parts.

[nicklouse]

just leave it as it is and be more concerned with and rules and regs you have to fulfil.

[MIGLIACARS]

If you go and the bug bites you will be hooked on it, so get ready to spend spend spend, once addicted its like a drug addiction but more expensive you have been warned, and good luck with it pal.

 

A 1522 3 syncro is no good what so ever unless u have to use it for the regs save it pal its a sort after casing.

[grizzler73]

As Nick says get the car prepared so it complies with regs and safety requirements, you will have a laugh. The first thing you will realise is that the major problem that is stopping you in going fast is not the car but you, that will be the biggest hurdle!

Good luck, motorsports is great fun, but you will spend...

If it’s a road car and if the regs allow, the best performance and minimum spend upgrade will be to lose as much unnecessary weight as possible. Remove as much trim and seating as allowed along with the spare (if fitted) and run minimum fuel. Basic stuff I know but it will make a worthwhile improvement. If you can find a rolling road it will be worthwhile setting it up before the event, if you can't, make sure it's had a good service with new plugs and points at the very least.

 

Your biggest problem will be the 2.76 diff, if you can change it out it for your other box with the lower diff and at the same time fit a cross pin diff (money well spent because it will transfer to your road car) it will pay big dividends. Practice your starts in an out of the way car parking lot prior to the event. Make sure the seat is a good fit and the belts hold you in position so you’re not thinking about bracing yourself on corners.

 

On the day, disconnect the speedo (so you're not spending your time looking at how fast you're going, rooky problem) and just work with the rev counter and make sure you can easily see it. Although it’s a road car, if you want to get the most out of it you’re going to have to accept you can’t be gentle with it. Don’t drive it like its you’re pride and joy out for a Sunday drive on the highway. High revs and dumping the clutch, hard braking and hard cornering are all part of it.

 

None of the above will cost much for a first event. When you’re hooked, be prepared to never stop spending.

Some suggestions for engine:

- 266 is a low lift cam, with std rockers you won't get good mid-top end performance

- suggest replacing std rockers with 1.4 or 1.5 ratio, this will make massive improvement

- BG needles are super-rich, has this been set up on RR?

But when you increase valve lift you also will see drop in low speed torque, not so good with SCCR and 2.76 FD.

Also worth paying close attention to distributor advance curve to get best overall torque curve.
