Gas Milage

Does anyone have a stock VW engine, one carb? What's your gas milage? I have a 1905cc, cam,large valves, two big Webers. I get at best 20 around town and maybe 25 28 on the road. I'm think of going with a stock VW 1500..maybe even smaller.

I have a 1600 single carb, on the highway it's around 30 but I have never checked around town. Smiles per mile, priceless.

Paul I have a 1776 single carb and I gotta agree with around 30 to 34 highway, but city i measure by WEEK! LOL.. I'll spend as much as 2 weeks driving her twice to and from work.. As mentioned before the smiles are endless!

Speedster "D" Just drive it Baby!

Paul,
Thats sounds like pretty good MPG to me. Why would you spend all that money to go down in HP for a few MPGs? It would never pay off.

Pure silliness to even consider it IMO.

you have a primitive fun machine not a gas saver you are lucky to get that MPG.

You won't enjoy losing the horsepower. I'd gladly swap engines with you!

Pure silliness to even consider it IMO. >>>>>>>>>>>

I agree with you. That's why I was asking. I thought maybe a stock VW might get 35 around town and close to 40 hwy. I once had a 1967 1500 bug. No one cared about mileage then. Let's face it, the air cooled VW engine are not the most efficient things going. Even the old Speedster 1600s data give 20-25 gas mileage. I have a 1992 Toyota V-6 4x4 truck, and it gets 25 on the highway.

Paul,

No offense intended. I have a 02 Passat wagon 1.8 turbo that gets about 28 - 30 on regular and cruises at 85+mph and is quiet as can be. VW made a thing of driving beauty when they designed that car. The newer Passats are not so good though.

In San Diego with my 1776cc speedster D and standard transaxle gearing I almost get run over by everyone unless its bumper to bumper and I can't imagine going to a smaller engine. If you have a lot of open road and not much traffic in AZ I can see your point.

BTW I am on my third tank of gas. 1st tank was 15MPG lots of idleing and street driving. 2nd tank 20MPG a little more freeway driving. 3rd tank is work in process.

Cheers
Dave

Paul, I have a 2424 cc engine. If I put my small idle jets in, I get a dramatic difference in mileage. I have a set for the commute, netting me between 28 and 30 mpg, and the larger set which get me somewhere in the 15-20 range.
My only pain in the butt is balancing the carbs when I switch jets. You'll get the hang of it pretty quickly; takes about twenty minutes, start to finish.
Just a thought.

Things I learned on my recent 3700 mile road trip.........
#1 A bag on the luggage rack = about 2 MPG loss.
#2 cruising with top up, side curtains in = 3 MPG increase!
We left Elko Nevada early in the AM. Top up, sides in, rack empty, got 30 MPG with a very loaded car running a 2110 at 65-70.
Home at last! Ernie

That's interesting..... I also have a small stroker and a cam. The Webers might be a little to large for the 1905cc.
Paul

From 40 to 44 Webers would be fine for your car. As Cory says; if you get it jetted for optimum your fuel mileage will tend to increase.

Corey's 20 minute jet swap/re sync. is due to the fact he can literaly step into the engine bay as required....It does make it so nice....

Dual 40 Webers will work from a 1600 up to a 2000 or so, no problem. If I keep my foot out of it(yeah right!) I can get over 30 mpg. That is a 1400 lb. Spyder, 2165cc, 3.44:1 final drive. Around town, lots of full throttle accel to 80, about 21.5 mpg. The price we pay for fun......

It is all about tuning (a/f ratio, timing), and gearing, and throttle. Here is a LOT of info

You'd be better off renting a LM-a from aircooled.net and jetting everything properly.
