WOW! Thanks for the info.

260HP was with triple Weber dcoe45 (Italy version) but I don't think I'm gonna keep these since I'm not familiar enough with carbs. This is a for a week end car. Not for racing.

If I stay with my SU, would I loose a lot of HP?

For your info, the motor is a L28 (don't know which one.... the vin have dissapear on the lock), E88 port and polish head with bigger valve, Racing springs, Cifford SS headers with Dual pipe, Perfomance ignition, don't know the spec of the cam. Racing oil pump, 7qt baffle oilpan, Oil cooler, ect..

The car was running on standard 94 octane gas. So don't the compression is too high for street use.

Thanks for you help,

Joce

Have you driven it on the street yet? While you would lose some bottom end with the big carbs, it still maybe streetable depending mostly on the cam. Many owners run around with 45 mm DCOE carbs on the street. I am running 45 DCOE throttle bodies and it is quite streetable, not to mention the rush when you get ON IT!

no haven't run them yet.

I would really like to keep those carbs on but I've been hearing that they need some ajustment depending ot the weather. Here in Quebec, we have all kind of waether all year long.

Also heard that it need ajustment almost every week to keep it perfect tuned

Also heard that gas can spill out on hard turn with no gas? It have a huge ugly plate underneath to avoid gas going on the headers.

Are these all true? And how hard it is to do the maintenance tuning on them?

Thanks in advance,

Joce

J.... enough with the teasing..... pics!!!

Your Webers are similar to Mikuni units. My 40mm Mikunis are a set and forget carb, unless you change altitude drastically. No problem with fuel spillage, although they can and do drip a bit on start-up sometimes. I'd say keep 'em. They're good units and will give you a turbo-like rush when your right foot gets heavy.....

I concur with Frank, only big altitude changes really affect jetting. Gas does not spill out in turns if the fuel bowl levels are correct. There should be a heat shield between the carbs and header to prevent heat soak.
