Will add some more details later, but here are the pics, battery was an HB028 from halford, would go for a sealed one in future with no cell caps to get in the way.

I'm more interested in the clear pipes, charge cooler?, if so where's the pics?

 

The pics dont even start to do pipes justice!! i nearly fell over when i saw them in the flesh! Plus the other bits!!!

Excellent work Paul!! do we have a Wallis Takeover Any more pics?

Rob

 

Well thanks Rob, more interest now

Come on Paul, I keep checking 22b as well but nothing since 22nd July...

 

There's lots of little things on the way. I'm making slow but steady progress.

Engine hasn't changed since 22nd July, concerntrating on the peripheral stuff prior to fitting the engine.

All has been photographed along the way.

For referance, the water pipes are about 42mm outer diameter, so yes, a bit large, 5mm smaller would have been better, but I may address this in future when I design and fit the engine side of the chargecooler. I need to work on getting air temps down, cold feed and rad ducting next.

Why not just stick the battery in the boot Paul? More space and better weight distribution

 

Obviosuly saving weight where possible is a good thing. How do these small batteries actually perform??
Due to the type of cars I have owned, I have always installed the biggest battery I could fit. Reason being, if it didnt start first time, then I always had plenty of power to try again.
Obviosuly a fuel injected car wouldnt suffer as badly as a butchered carb car, but I always like to be safe.
Once your battery is flat, even a push start wont work. There needs to be at least some power to drive the fuel pump/ignition.

 

Steve, that is why I've used the biggest small battery I could find. I think it's about 25ah, whereas Andy F used something like a 16ah battery.

I could have put it in the boot, I purchased enough cable to do it in the future. However, I like my boot space just as much as my engine bay space. If the battery were slightly smaller I could put in the side compartment though.

What about one of those dumpy sealed ones underneath the driver or passenger seat?

 

I could have done something like that I suppose, but would need 2 batteries in parallel I should think. You can get some sealed anyway up" batteries for a lot less than the Varley racing batteries. It is something I will consider if I find I am in need of further space.

Currenty battery was quite easy to do though, I think.

Paul

 

How powerful actually are these small batteries in real terms?? And what roughly is the weight saving?
Would they say allow you to wind the engine over for several minutes??

 

if you need to wind it up something is wrong anyway

 

yeah but how you supposed to fix it if you can cant crank it.. and dont have a booster pack?

David

 

It's a reasonable sized battery. no problems as yet, and it's not a great starter at the moment do to fuel pressure issues of some sort

Paul

 

Neat little battery there Paul.

It's not the best time of year to find out if the battery will be up to it... being so warm. Mind you, if Mr Forrest is running 16AH throughout the year in bonnie scotland, then that would be a good sign, assuming he uses the small battery all year round.

It would be interesting to see how much more current drain on cranking you would get on a 9:1 or similar compression engine... the battery may need to be beefed up again if the C/R were increased.
