The Great Debate! Carb vs. EFI
« on: May 31, 2008, 02:50:48 AM »
I have a freind that I have known for twenty something years and he is a "Fuel Formulation Engineer". He works for a refinery in Richmond and he started talking about something very interesting and at the same time very curious (he never talks about what he does like its technical), He says that in order for fuel economy to improve dramaically with todays whimpy fuels (referring to BTU's/lb.) we need to go back to the carburetor... WTF!!!. I thought with EFI we were on a path that would eventually start to improve fuel economy and emisions. But what he said next was even more strange, staring at a 1986 Dodge POS in his field, If someone built a turbocharged carbureted four cylinder with super high compression (he did not specify but I assumed in the low teens) and ran E-85, it would be more fuel efficient and cleaner than any other non-hybryd on the road. I've been thinking that fuel injection was not all that impressive when were talking high performance wot stuff but holy crap! :screwy:,

So stay tuned because I thing we're building a high mpg turbo Dodge Colt that has been in his backyard for about 10 years its MPI right now, but he wanted to know if I still had the Weber carb from my old Toyota 4x4, this is going to be fun ;D.

Anybody have any thoughts? I can't help but think about that hydrogen generator you  :sly: :sly: :sly: were talking about.

He also said that Formula one is going Hybrid next year? I feel old........

(E85) Exactly. The sh!t burns clean, has a huge tuning window that will help with super high compression engines, with or without boost but the more the boost (to a point) the better. I personaly feel that E85 is a hugely untapped (for the most part) fuel that is better than gasoline in every aspect once all the issue's of E85 have been contended with. If a swap was going from E85 to gasoline changes would have to be made just like switching from gasoline to E85 requires changes.

It seems that some people try to compare their 91 octane pump gas to 105 octane E85 and then they say well E85 burns 15% - 30% more fuel and since it's not 15% -30% cheaper it isn't worth it, but they don't compare 105 octane E85 to 105 octane gasoline which is way over $9 a gallon out of the drum. Not to mention the stand alone benefits of E85 vs. gasoline.

BTW, the carb vs. EFI is just crazy talk. EFI has far too many advantages when it comes to power and economy. BUT, I ain't know engine-ear either.  :banghead:

Yea, I don't understand the need for a carb, when you have so much adjustability in FI with fuel mapping programs and different flow injectors if necessary.

The reason for the carb had something to to with vaporization cooling effect and overall vapor pressure, to be honest that was at about the third bourbon and Coke :-[ , but I do remember he said draw through system not blow through, which also seemed "odd", BTW this guy used to build some stupid fast snowmobiles in the late '90's and they were never fuel injected, maybe just comfortable with them?
 More food for thought, I used to drive this little POS Honda accord two door '83 five speed 150k mile + and it was carbureted and it got 40 mpg, but like he says, on the "old" gas...

I remember back in the 50's or maybe the 60's (early) there was a guy from Mid State California that developed a carb that would get a car somewhere around 150+ mpg in a regular car.  We didn't have these juice boxes they call cars back then.  I think one of the oil companies paid  >:D him off so he wouldn't develop it.  Maybe that's what happened to the guy here just recently who made a way to burn regular tap water via separation.

Welcome to "free enterprise", go ahead and do the research so we can control and tax it then find out its feasable, have you bumped off, then sell the ideas to the Saudi Arabians so we can pay big bucks for the  technology, so you can be taxed on it again, and have no control over the price so we can "general fund" the percentage from the taxes so our politicians can get their well deserved raises. :mad: :mad: :banghead:


Holly hell, where did that come from. That was not very positive I'll try to lighten up... :screwy:

If fuel injection had been invented first you wouldn't even know what a carb is.
There would have been no need to invent one  ;D

Anything a carb can do FI can do better  ;)

If you want to see how Big oil controls things search the Fish Carburetor and read how the I.R.S stoped the U.N.S.P service from shipping Fish  Carb. I Had friend in Riverside ho  had one I hope to get it some time he passed away not to long a go. Here is head that I am working now for my grand sons race motor Pro 4 Its a ranger head ford 8 spark plug type EFI head . It has been changed to a carb type see adapter on manifold that we made. Inj have been bulged it will fire 8 plug at one time The head has been angle milled to 45cc and a solid  roller cam set up in place ported & polished big valves . In picture you can see the roller rockers, cam will have towers
machined for roller cam berg . I am building one of these heads for my 79 Mustang Ind pace car 4 Cly Turbo Charged with full boast and Electronic Vara- Jection water Inj with alc this way can run more compression and more boast. It will be a 5 speed car for gas
millage if it works out I will build one  for one of my flat bottom boats I have. I will soon have water inj on 454 boat no shortage in lake water and can force feed large spray from lake to Carb. Been playing with water inj for lots of years Spray bottle to clean polished chambers water
and alc spray over Carb fast idle ruining. cleans carbon of Pistons and chambers best on new motor and new heads to keep them clean

I loved the Pro-4 series.  I worked as a crew member a finally a crew chief in the MSRA Pro-4 series for several years before going to the ASA Speed Truck Challenge.
