Gas $5.00/gal. - What kind of mileage motor should one build

[bigbore]

Iam doing a single port 1641 with a Eagle 2229 cam which is adv duration 260 and lift at the cam 299 this is a very mild cam but this engine is going in a 68 westy high top the carb is stock 30 pict 2. stock 205T dist completely rebuilt with new points plate shims and nos can. some lite port polish on the heads and a 1 3/8 header . Iam using a duel oil relief block and late oil cooler so it will have the better oil cooling. I have a stock 71 westy a stock 69 westy also to compare it to when it up and running it should interesting. I thought about running a duel port intake and 34 pict carb but I don't know if it would be a worth while gain.

hi you can use a 34 pict carb on your single port motor . empi makes cast alum end castings . all you have to do is find a 34pict carb and stock intake manifold . and your good to go . nice motor you built years ago i used that cam . it was one street friendy cam .you will like it a lot spencerfvee...........................

Ya I saw those ends but thay sure are proud of them at 50.00 a pair where they only get like half that for the duel port ones well it may be worth it I have plenty of the intakes and carbs to use and a svda that would have to go with it all.

i think john guards them .like they were gold . lol so hows south africa ? do you belong to a vw club .? what kind of vws do you have ? and hows the weather . its cold here . spencerfvee..................

[spencerfvee]

has any one done a test of a stock vw muffler to see how much it hurts power and milage with stock exhaust tips and if straight pipe tips help power out put . i saw where a ralley bug over seas made 125 hp with gutted stock muffler thanks . spencerfvee............. .......................... i know every ones seen gas going up this week . i read on yahoo news today that gas is over $5.00 gal in some parts of Cal. here in ohio gas is now $3.70 gal. i dont know about every one else but its made me rethink . about building a MPG motor . i am sure others might be thinking about doing the same thing i allso am sure that your going to see more fourms on thesamba on building a MPG motor .i am sure theres guys with lots of money that dont care what kind of MPG there VW gets lol. i would like to know what what year vw would be best to put a MPG motor in . what would be the best VW transmission to use with a MPG motor .and best tire size to use with a MPG . and what would be the best MPG motor to build maybe a 1200cc motor 1300cc motor 1500cc motor or1600cc motor or a bigger cc motor. my self i am thinking about building a 1300cc motor with a 34 pict carb single port heads a 1968 auto stick dizy with 009 bosch dizy parts . a 1 3/8 header. CB cheater cam . spencerfvee

My newest engine, 2275.
Pretty standard fk-8 and homeported heads, some fancy stuff do.
Drove it 2 hours some days ago, sporty driving with undersea tunnels and it did 43 mpg, no fancy SS pistons.
Just roughly tuned, much left in final tuning...

I find this all funny I have lived over seas and paid more then this 10 years ago and for all of my vw mech years (about 35 of them) I have built small ( the biggest 1776) mostly stock vw street engines drive them sanely get what I think is great gas MPG and Iam happy I knew these prices were coming Iam not upset Iam in hopes it will get some of this stupid unnecessary big cars and truck off the roads. now the world gets say to the US see what we have been paying how do you like it but I know friends I have in the UK and in europe are paying 10.00 plus a gal now.

Spence, You can look at a couple of ways I guess. If you are driving primarily in the city then a light Beetle would be best. I'm guessing the split and oval windows would be lightest therefore easiest to accelerate. Or you could get a 60's era Bug and go crazy with fiberglass front end and fenders and engine cover, maybe even some lexan windows, gut the interior, aluminum door covers, etc. Not my cup of tea but it could be done.

The other way to look at it is if you do primarily freeway driving then you'd go for something a little more aerodynamic like, as Krusher said, a Karmann Ghia or a Type 3.

I feel a displacement of around 1700 to 1800cc with a small stroker crank would be a good foundation for a mileage motor that has decent power for any of the above vehicles. If you just want good fuel mileage without the power a smaller 1200 or 1300 would do it.

hi darth weber . every thing you say is true .about milage for a vw bug thanks for your input .darth i started building my 2,180 motor befor i thought of building a milage motor it has a 34 pict carb. on this big motor. i hope to see if it will get good milage with a 30mm venturi in a 34 pict carb .. i can go down to a 29mm 28mm ventrui . it will be fun to do and se what hapens . i am shocked at how many people have given good info and feed back on this forum . the nice thing is that no one talked trash talk to each other . that was real nice . . its been a lot of fun reading the posts . i have gotten some great info . from these post . allso i dont think some people undersatand . how nice it is .that guys like you darth and john at air cooled and many others and lets not for get the over seas guys that have given great info too alstrup of germany who helped me out on my carb set up . and UK guys and a guy from africa and others .some who have shops to run that have posted on this forum .. that have taken there time to post on thesamba that is super . most guys with shops . charge money for info. if you go to there shops. trying to find out about something for your vw . most guys with shops will say bring it to my shop and i will do the job for you . some shops say my time is money . i dont give out free info it happens . . and thanks every one that has posted on this forum . from reading the posts on this forum. i have found out that every one has a motor combo that works for them . i think that a big or small motor can get good MPG . its how you drive that makes a big differnts in MPG . my self i am enjoying life and having fun .i am thank full i can still drag race and have a street bug .. i just saw where davy jones lead singer of the monkees just passed away from a heart attack .today so enjoy your vws . while you can guys lol keep the post comming every one have a great day spencerfvee................................................

i just dont understand why we dont have motors like that in the USA . how fast will they go on a free way ? will they do 70 to 80 mph. ? 63 MPG i would by one in a heart beat . i think the V 6s are on there way out. i know at my mazda dealers they are a hard sell. no one wants V6. who would belive a 4 CYL. motor would take over so fast . you UK guys get a choice on motor here in the USA most of the time we dont my 2012 mazda 5 van has only one motor a 2500cc motor on the mazda 3. 3 motors a 2000cc a 2500cc and a2000 cc sky g motor oh and the mazda speed 3. 2300cc motor turbo .and the mazda speed 3 turbos are not selling well at all now. they take high test gas . spencerfvee

When I was living in the UK back in 2001 I got to look at and drive a lot of cars we don't get here. The Audi TT that my wife has 1.8T gets 33 mpg on the highway 25 in town and its a quattro lots of power and fun to drive.
