| Post subject: | SU, Webber or Dellorto? |
I think a lot of my idling and tuning issues are due to the linkages on my 1 3/4 SU and i think i've decided rather than spending anymore time and money on the SU i'll get rid of it and put a weber or dellorto on. i'm leaning towards dellorto as they seem cheaper to obtain. Question: Are the Dellorto's easier to tune? i'm guessing that more tuners out there will understand them and be able to work on em? is this a fair call. also my car has a lumpy cam in it, will the dellorto enable easier tuning for down low and up high versus the su? cheers. |

I run a 45 Dellorto on my 1360 and love it. I find them easier to tune than Webers, perhaps because I've done more of them. But there are pros and cons with either, compared to an SU... Pros: They look good. No throttle spindle bushes, they use real bearings and seals. They stay in tune better. They (usually) give more top end power. The sound is great. Cons: Much more induction noise. You cannot stab the throttle at idle like an SU (it's not an on/off switch) particularly with big chokes (for power) in it. Hard to fit in the car with a decent manifold AND air filter. May need a Weber box put in the firewall. Less bottom end and midrange torque than a good SU setup. Poorer fuel economy. Cannot use vacuum advance to the dizzy. |
