For people who have upgraded to Weber, what kind of MPG are you getting?

Also, has anyone dyno'ed their car after installing Weber?

I get about 28mpg average with the 32/36DGEV. I dyno'd my car and I figure it's about where it should be for stock power with 280,000 miles.

I pulled 67whp on a Mustang dyno. The car is rated at 86bhp. So factor in a 15% powertrain loss, and that's 73whp stock. So I figure after so many miles, missing 6hp is doing well.

I wouldn't expect it to give me any power gains anyways. The stock size of the carb on my car is 32/34, so going up to a 32/36 isn't going to do much. And I can't speak for the carb on the 3geez.

A whooping 86 horses; that's amazing! What was your MPG before installing the Weber?

People with 3Geez and Weber seems to be experiencing phenonmenal horse power and torque gains at the low RPM range, according to postings in this forum. However, not many people with Weber's seems to care about MPG.

I'll tell you, it's far from phenominal power gains. It's barely noticeable. If anything, it's more than likely the noise that makes it seem more torquey. Before, I was getting about 28-34mpg. Now I get 28-30mpg.

Maybe with a cam, and header, you can get some *decent* gains with a 32/36, since it can be tweaked to match the exhaust and cam upgrade. However, I believe most of the gains are likely felts with a 38/38.

I'm getting about 27MPG with my 38/38. I also have a stage 1 triflow cam though.

Those are very reasonable MPG, so I think I'm going to upgrade to a Weber as soon as my Keihin dies.

Be prepared to do some tuning. Mileage won't be so good if the carb isn't tuned well.

Oh, and a wideband O2 sensor makes it WWWWAAAAAAAAYYYYYYYY easier to tune.

I agree wideband, and a screwdriver, and some time working out which jets you might need to swap if any.

The "kit" is supposed to have the proper jets.

Hahaha many things are supposed to be. But many things aren't as they seem.

The kit would get you in the ballpark, good enough to drive at least. But not necessarily optimal.

the greatest advantage of the two stage "oem replacement" 32/36 is it is a hell of a lot easier to work with, much simpler. I did have a lot more power but then I did exhaust work and head work at the same time.
I would do it all over again on another A20 if given the oppor-TUNE-ity.
You definateley will get power gains with DCOE webers, they are NOT two stage like the 32/36, 34/34, etc.

Wow, no kidding there. And my 38/38 is even simpler since it's a single stage. I can change jets in 10-15 minutes with 2 screwdrivers.
