drag race fuel injection

if fuel injection is so great then why do all racing vehicles use a carb?

drag racers, nascar,road racing bikes all use a carb. So whats so great about fuel injection?
especially drag racing,all top fuel drag racers bike funny cars and rails usse carbs to just DUMP fuel into the cylinders.

Carbs are becoming more obsolete every year in almost all forms of racing. As one other answer states, for NASCAR, it's in the rulebook that carbs must be used. As far as ALL top fuel fuel racers using carbs...not even close. More and more are going to injection, simply because it is EASIER to dial in for different tracks and atmospheric conditions....no more mechanical work to change jets by "guesstimations" as to what is needed. With O2 sensors and on-board computers that record what the air fuel ratio is, all you have to do is a few clicks of the mouse to richen or lean the mixture in SPECIFIC rpm vs. throttle postion openings vs. manifold absolute pressure. With injection, you can get max power at EVERY specific rpm and throttle postion...with carbs, all you get in an "across the board" change in low range, mid range and WFO, gaining more somewhere in those ranges will cause a loss in another range. Carbs offer no where the fine tunablity that injection offers.
Try tuning a carb on the dyno and find a lean spot of 16.2 a/f ratio between 3200 and 3600rpm that is causing a loss of 6 hp...considering that 3200-3600 is the center of the mid-range where most riding is done, 6hp is a MAJOR loss. If you richen up the pilot jet to compensate for that lean spot, it will richen the entire mixture ffrom say 1800-4500rpm, now you will have to readjust the idle mixture leaner to compensate for more fuel from the pilot jet, also this will richen up the top end circuit which pulls fuel from ALL circuits...now you have a drop in power on the top end that will need to be adjusted by leaning the main jet.........with injection simply richen up the mixture from 3200-3600 until you have a smooth/flat fuel curve with no loss in power.
This doesn't even include even further fine tuning for different throttle position openings and manifold absolute pressure.....something carbs don't even have tuning capabilities for.

The benefits of injection are limitless if you know how to use it...PERFECT engine tuning for MAX POWER AND FUEL ECONOMY SIMULTANEOUSLY for EVERY CONDITION, RPM vs. THROTTLE POSITION vs. MANIFOLD ABSLOUTE PRESSURE. I could go on and on...but this gives a good example. I have put identical bikes on the dyno, with the exception of one being carbed and one injected, same motors, cams, heads, pipes, sprocket ratios, etc and gotten more power from the injected bike than the carb with easier tuning and better mileage....you can tune the a/f ratio while still sitting on the bike with it running simply by clicking a mouse.....no getting off the bike, waiting for it to cool down so you can pull the float bowl 4,5 or 6 times for a jet change or needle clip position change, put it back together, warm it up, run it on the dyno again just to find out you have to do it again.....then, after the a/f ratio is dialed in, you start on ignition timing....AGAIN....INFINITE adjustment capabilites in 1/2 degree increments for every 50 rpm for absolute fine tuning.....all while still sitting on the bike.

Not only that....I used to live in Phoenix, I know what riders there do...try taking an S&S dialed in for Phoenix up to Flagstaff without fouling a plug or puffing black smoke out the exhaust. Try starting an S&S in 25 degree temps without fouling a plug from the enrichener DUMPING raw fuel down the manifold.....with injection....HIT THE BUTTON, it will do the rest from 25 degrees in Flagstaff at 7000ft elevation all the way down to Phoenix at 1000ft without missing a beat or fouling a plug.

Also, not mention forced induction and nitrous installations...take nitrous for instance, with a carb, you have to add a secondary petcock feed to an electric fuel pump and meter the fuel with jets, trial and error until the optimum a/f ratio is achieved...with injection, basically, you simply set-up the computer with a secondary fuel map to turn on when the nitrous system is armed and the throttle hits WFO and thats it.....

Boss EFI Simple Electronic Fuel Injection

What's the maximum power that a Chevy 350 engine can produce, naturally aspirated?

Without nitrous, supercharging, or a blower, what is the maximum about of torque and horsepower that a Chevy 350 engine can produce? Perhaps I need to be more specific, so let me set forth the parameters:

1. The engine must run on pump gasoline
2. Ergo, the compression ratio must be apx. 11:1 or lower
3. Any cylinder heads are acceptible- aluminum or iron
4. Boring out the cylinders is fine- 0.030, 0.040, or 0.060 over is acceptible
5. I prefer that the engine is not stroked to a 383 stroker, because I am more interested in the limitations of a 350 (but, again, it can be bored out)
6. Any camshaft is fine
7. Either fuel injection or carb is fine- though I guess using a carb may provide more HP
8. Any crank and connecting rods may be used- iron, aluminum, or steel
9. This can be a drag race motor, or a daily driver
10. No budget limit- no expense spared, if need be
11. Lifetime/lifespan of the motor can be anything- 10K miles, 50K, or 100K.
12. Reliability is preferred

If no expenses are a problem then get a nascar engine I believe 355 cid at about 800 HP but wont use pump gas.But to be reasonable with a steel crank, aluminium rods and whatever pistons (assembly balanced and blueprinted) and heads give you the compression ratio you are looking for. A set of heads ported, polished and put on the flow bench (2.02&1.95 valves ) A roller cam of about 296 duration and .550 lift. Roller rockers, good intake manifold, eidlebrock 750 competion carb ( I am prejiduced could not to get a Holley to work as good and a lot easier to jet ) Once you figure out your components, put the engine together as if you are going for 8000 RPM reliability and never take it over 7000, will last for years. Put together a 327 similar to this and made over 1000 runs down the drag strip( 5 years of racing) and only ever had a rocker stud pull out. Put this engine in another car and raced it for 2 more years. This engine produced about 550 HP ,so reasonably you should get about 600. But most Hi Performance engine shops will all have their own ideas and that is a good place to start.Just do not make the mistake of over camming or over carbing the engine. Small Blocks RULE.
