i by no mean disagree with what ur saying. what my car can do that yours can not is automatically make fuel changes and spark changes for temperature and elevation without popin the hood. i can make fuel changes in milliseconds per cylinder. i can run a closed loop set up with a wideband so maybe for some reason the fuel pressure drops oh shit now i'm lean so then it can add some fuel and take out some timing automatically. save my 20000 dallar engine. my system runs at 60psi so if i drop 1 psi chances r its not ganna go lean.....your 8-9 psi system u drop a half psi on a big nitrous kit and shit happends quick. i mean the list can go on and on.......i am not sayin that you can make an ungodly more amount of power with an efi system what i am stating is that they are more tunable more safe more controls.....

thats why you have a good fuel pump so it wont drop no pressure. the only thing fuel injection can do over carb motor is driveability. it wont make more hp or go faster.

mike moran knows his shit. i just get lucky and go to the right people for the work i do have done. i just wish i could go back in time cause all the parts on my car were pretty much availble back in the day so it would have been badass to beat up on all those crazy combos they had then.

yea i agree a good fuel pump is ideal but shit doesn't last forever. never said it will make more power or go faster just said u will have way more control of your engine and u don't have to pop the hood....well i'm outta here i've made my point.

EFI or carb, tuning is tuning its fuel and timing. Engine requirements are what they are. guys like billy glidden may not use efi cause there current set up works. A lot of people are afraid of EFI, systems like fast and big stuff are getting easier to run so they can market them better. factory engine management on the other hand isnt as easy.

I'm not knocking carbs or EFI. However I didnt see widebands in anyones carb car untill efi got popular.
 
carb 800.00
dis7plus 700.00
n20 controller 300.00
jet kit 80.00
power valves 50.00
wide band 300.00





f.a.s.t xfi 2000.00
factory efi free

Forgot MANY necessary components with the EFI example....

about the only part that may need to be upgraded on a factory efi system is the injectors and for boosted cars maybe a map sensor that is if they aren't running a maf. bigger fuel rails and lines is part of the fuel system not the electronic system. pretty sure carbs need big lines and pump also......so i'm curious to what the many parts that may be needed??? jquick have u ever had a wideband in your car?????

I left out crank trigger for both set-ups seeing both would prolly use them.
efi would need inj. and TB as well. I don't know if I consider that MANY or not

no crank trigger needed, you dont ahve to run a dig 7 either. the only functions i use on mine is the retards if i wanted too i could lock the timing down for 1kit and use the retard on a dig 6 for the 2nd kit.

nobody uses a controller only people who dont know how to make their shit work or run a drag radial and going fast

who uses a wide band? plug reading is the best way to go

what does a power valve have to do with nitrous?

and for your example for fuel injection, what is a fast or big stuff 3 gonna do sitting in a box, you still have to have the knowledge to use it.

ok lets set a budget and i bet ill go faster with a carb and nitrous then you will with fuel injection and nitrous.

no i read the plugs. only true way to do it.widebands dont work cause it will change reading on where you put the 02 bung at. a plug reading tells you everything.

yep. the wideband will show total a/f but you still could have rich and lean cylinders

true story. now tell me JQ how do you adjust individual cylinder trims on a carb mtr. with a dis 6 box?

your dis 7 has EFI technology. you can pull timing, use traction control, adjust individual cyl. etc.

I agree when pushing the edge plug reading is the only way, afr only gets you in the ballpark.
 
If I ran nitrous or N/A I'd definitely still run a carb. I held out as long as I could to switch to EFI, I think it was in like 93 I finally switched, and only because I got addicted to boost. It's the best way with boost.

EFI is a lot more expensive though, the fuel pumps, regulators, injectors, throttle bodies, rails, computer, and tuning all add up.

Just curious, why do you guys feel that individual cylinder control is so important? I can see if you're heads up class racing or something and you have to go .001 better than the next guy with the exact same parts or something, but for most of us on this board, I don't see why it's necessary. I've never used any of that stuff, never once had a car tuned near the edge (except back in the day with a KB and 300deg ACT), and I've run from 13's to 8s at all different boost levels.

I know the intake flows different depending on the cylinder, but I've never had a car that was on edge enough to matter.
