Webers, We do I start. I ran them on one of my engines for a while. IDA TYPE that is. And will be running them on my Group NC Race car when it is finished!They are the best for WOW factor! If you want to race the car on a road circuit, they are very good. They give you a lot of low down torque for out of the corner acceleration. They are very expensive to tune, and getting someone who knows what they are doing with them is getting very hard to find that has the know how to do the tune. Just remember that when you are tuning them, they need to be done in the car and on a chassis dyno. Also, Every engine is different, so out of the box they will need tuning, so you will be up for everything x8, main jets x8, idle jets x8, chokes x8, emulsion tubes x8 and the list goes on!
Once they are set up properly, they are excellent. They do not like a camshaft with a lot of overlap, (too much reversion).
A lot of people say that they are always going out of tune. They go out of Sync, not tune once they are tuned. If your price is $5k US for the setup I would expect $10k fitted, balanced and tuned. Frank, I would say and suggest that you would be much better off with a single 4 barrel carb and manifold package. Much easier to tune and a lot easier on the wallet!
I hope this gives you some insight into WEBERS!
