I beleive the Pinto set I did had spacers to get the spacing closer.  The manifold was a fabbed item from the UK.  The carbs came with the main jet already bigger (1.9mm-2mm from memory)
 
The engine was one of my mild road car packages, made 95rwkw on the dyno i use (143fwhp).
 
Overall, the wide open throttle mixtures were basically spot on, but at part throttle and just off idle it was hesitating.  This was rectified by drilling the pilot jet, from memory 2 sizes (we remember having the carbs off twice).
 
It is important they are mounted on the correct angle (as they would sit on a bike) which would appear to be about where you have them.

Thanks Woz,
 
Did you do adjust the needle jets at all?
 
Any pics?
 
What are your thoughts on these vs webers?  From all my reading it seems there is not really much in it but that properly set up webers (meaning dyno'd) may be better for all out race cars where most of the time you are at WOT where as the bike carbs are a bit friendlier around town.

From memory the needles were left alone.  When we finished the tune on it it would literally pull from 1500 rpm right through to 6500 without any problem and was quite pleasant to drive.
 
I don't have any pictures, and the owner sold the car off a while ago sorry.  I beleive it ended up in NSW.
 
In regard to these versus webers I haven't had the opportunity to do some real back to back tests.  Because of the angle they have to be mounted on I beleive that the webers have a better entry angle in relation to the port, especially on a Pinto.  This doesn't effect other engines however.  In regard to flow and how the carbs work etc, and power, in my opinion they are just as good.  The design makes them very drivable down low (better than webers) whilst still retaining good flow up top.  I think you would probably reach flow potential given the right engine though.  I'm keen to play around with a set on one of my more powerful engine builds at some stage, but I think they would start to fall over at anything over a genuine 170-180fwhp.  I could be wrong.

Bang for buck they are pretty hard to beat.

Absolutely, I wouldn't hesitate in using another set at all.

good work - nice & informative
 
found these the other day as manifold options - look interesting -

Not bad, you need to weld them obviously and work out the right agles to mount them at too.
 
You may be better off just getting ready made ones if you don't have the skills like me.

nice thread- thx
got me thinking - but i cant get too ahead of myself - i havent found a donor engine yet.

for those interested - i found these easy enough - not sure if they are same / equivalent.
 

Those are 38mm carbs where as the R1's I used are 40mm.
 
Probably no difference on a mild engine but you'll be lacking top end power if you start modifying things.
