Just wondering if anyone has put S.U.'s on their van, and if it was any good. Or even those funky little Minnow Fish carbs? I know how to do it - fabricate manifold and throttle linkage etc - I was just interested to know if it's worth it? Specifically for an Aircooled, but I suppose for WBX's too. Might make a (refreshing) change from Webbers, and trying to rebuild Solex spindles.

I was reading this link http://www.yakthehairy.com/ebay/minnowfish.html about minnow fish carbs. They sound brilliant! Its a wonder theyre not more popular. Could be an interesting project for you, Dubstar. Are they easy to come by? As for fitting a set of SU carbs, you could get a set of twin SU's out of an MGB. They were very good quality ones too. Very big though. You'd pick them up at any car show really. Ive always seen loads fo them for sale, in various conditions.

If you really must!!!! a LOT of messing around...

Anyone interested in a Fi system that will improve economy, power and emissions... ?? either to replace the standard DG carb and AC solexes and an option to replace the DJ/MV ecu's too...

Another little project I am working on...

From what I understand its less messing around than fitting an uprated set of standard dual carbs.

Suggest Mini Cooper Eaton Supercharge kit
Using LPG to cool charge in stead of Intercooler.

A friend put twin SUs on his 1776 bay a few years ago good results
I have a Minnow fish carb in my garage somewhere
I spoke to Bob Henderson in Argyle a few years ago. He was the manufacturer. He still sold new ones, which where £175 He also rebuilt S/H ones for £40 don't know if he still does.
The Fish carb was an american design I beleive. There were manufactured in the UK by Reece and Minnow I think they fell out at some point.
Bob henderon wrote a book on turbocharging
He was turbocharging VW beetles long before the Americans
Ford wanted him to make Fish carbs for them he declined.
He designed and built the ill fated Argyll supercar. Probably one of the only Scottish cars.

i`m a big fan of su carbs they have the advantage of not having to choke them down to creat a venturi so in effect a 45mm su is equivelent to say a 55mm webber ect, but without the lack of air velocity at low engine speed/partial throttle openings.

only downside with them as far as i see is they take a while playing with needles/springs to get the fuelling right and the fact that BIKE CARBS are basically the same design,easier to get hold of,lighter,more popular with rolling road operaters and are newer to start with.

also making manifolds for bike carbs is easier as they mount to a tube. ie no flange on the carb side of manifold.

they are getting very popular in the rally scene and are proving to be reliable.

S.U.- Sodding Useless

SU care good carbs! The only reason I ask is that rather than try and rebuild the solex's, which seem an overly complicated carb anyway, with hard to come by/expensive parts, that SU's are easier tom come by parts for and are much cheaper. And better. In my opinion of course.
Now obviously a full multipoint, computer controlled fuel injection set up would be better, but I think it would be simplet to fabricate a manifold and linkage for a set of SU's, and cheaper than buying a set of 40 Webbers.
Not that I'm gonna do it of course, but I do have a set of HS4's off a TR7 sat outside. Still attached to the TR7 engine. Now where's that pipe bending kit......

i have often thought about using bike carbs

su's or stromburgs are good tho

SHUSH!!!! dont tell anyone..........

I wonder if a Hyabusa engine would fit........

It will fit... but it would be hell to run... and you would have to lower the gearing so far....
2 might give enough grunt....

I think if I put 2 CU engines back to back and then put a supercharger and nitros it might give me similar grunt to a Hyabusa engine I was only joking about fitting one though. If you did though, I would imagine you would use their gearbox and attach the driveshafts from the van direct. You'd have to rev the stuff out of it though. Might be a bit tinny and noisy in a tinny and noisy van!
I'll just stick to my SU dreams for now

Anything is possible....

2 'busa engines wouldnt be too bad... wheel spin would be an issue I reckon... 1 driving each rear wheel...

anyone got a couple of busa engines laid about?

Oh... now you could use 3... drive the front end via a syncro diff etc...




I better stop now.... I know I shouldnt have tried those little pink pills laid about at work!!!!!!!!
