Re: fuel injected or carb?
ok this topic is getting just plain fucking ridiculous.
carbs suck. the end.
an engine with more than one cylinder is really several engines connected together by a common shaft... ie the crank. due to machining tolerances and everything no 2 cylinders are going to be EXACTLY the same. there for EFI can be used to trim each individual cylinder to its optimum output. if carbs were so fucking great why did the OEM switch to much more costly efi?.
the simple answer, long and short is that efi is better. carbs are antiquated. you need to be able to adjust fueling and spark based on many different inputs while the engine is running. carbs simply cannot deliver that kind of performance. believe what you want, spout whatever bullshit you want.
however, this is what it all comes down to. an EFI is a computer based system. junk in, junk out. the EFI will only work as well as it is programmed. if you lack so does the engines performance. carbs are easier to get in the ballpark so alot of people like them. ALL oem engines are going to injection. both high and low performance alike.
to say an efi runner has to be long is ridiculous, you can run injection on any manifold designed for a carb. just add some injector bungs and a carb body with no float bowls... ie a throttle body. to say carbs atomize the fuel better is crap. if you can suck fuel out of an emulsion tube you can do the same through an injector.
im so tired of this argument. if you want a powerful street car that you can drive every day, hot or cold, something you can let your wife or mom take to the store with NO SPECIAL KNOWLEDGE of how to operate it go EFI, and buck up and let someone tune it thats knows wtf there doing.
if you want a 1970 chevelle ss and all its inherent problems then by all means get a holley 750, mechanical secondaries and drown your poor little 302 in fuel.
ultimately will a carb make more power? maybe maybe not... whats the chance your street engine will be built to its ultimate potential.. not real likely.
im sorry but technology moves forward for a reason. the engineers take what they learned last year and improve on it this year. as this happens refinements will happen, things will change. hard headed purists will resist. but the ball keeps on rollin. why do you think it took harley 100 years to build a better engine... not because they couldnt do it {even though porsche designed the vrod engine} but because people resist change.
once again. carbs suck. efi is the way of today and tomorrow. if you dont like it run a carb, and trailer ur heap to the track. because not only do i race my car, but i have to drive it to work everyday.
last but not least engines with carbs dont last as long. because they overfuel when there cold and wash cylinders down which kills ring life. when the motor is cold they cant add more fuel {except for choke} and when there hot they cant lean out. same with ambient air temp etc. thats why you have to tune a carb car for track conditions as where efi does it automatically {assuming your correction tables are correct} why do you think engines today go 100,200 even 300 thousand miles and more without a rebuild, but 20 30 years ago youd be lucky to get 50k before tearing it down. and no metallurgy is not all there is to it. refinement is the key.
