Carb of EFI

Good grief you guys... Top fuelers don't have carbs, they are mechanically fuel injected. Basically they are EFI without the E.YA!! So THERE!!!! Put that in ur pipe and smoke it.
So really, I wasn't sure about that so I assumed they were carbed cuz Ethan posted it as such. Shame on me for not being better versed in top fuel cars and also for believing him.:o

Didn't I say that?

I suppose each application would have a different outcome, but on sprint cars (something I know from experience) just going from an alcohol carb to a hilborn injection (mechanical) is right around a 75 horse increase at upper rpm(6500-9000) but at lower rpm around 3000 (which besides idling and warm up sprint cars never run at) they are close in hp, a slight edge for the injection

Ok, since everyone on here knows everything.....is 6.5s good enough?no, cause top fuel drags dont have a problem running into the 4's...

you asked if it was fast enough, and i said no because it obviously cant compete with non carbed race cars, just like you on only two wheels. kthankxbye

very good apples to apples comparison(TF v. PS)...congratsplease list the other "non-carbed"(good way around EFI) racecars PS can't compete with. Oh, and make em N/A too.

Aw Wes, someday you'll get yer own sack and be able to stop riding Dave's.
Now, where did that come from? I stated the truth. I really wasn't sure so I did assume you were right. But I did know that there were tight regulations and limitations as to what they run.
Now, How is that riding the old mans sack? -

you cant compare cars from class to class, hence the reason they have classes. I was simply stating that no, carbed cars arnt fast ENOUGH because there is better technology available to do so. There is no way a carb is the most efficient way of tuning a car or making power when you are talking about milliseconds and pluse widths with fuel injection. Matching a jet to airflow pressure etc etc may be thought of as a science, but it is superior to injection only in simplicity. Just the way you are sitting on a computer instead of tapping out strings of dots to communicate with all of us.
dont automatically think i was trying to be a dickhead with my first post. Not everybody on here is out to get you.

Alright I'll ask how many on here have tuned a carb or ran a carb for any lenght of time? If you preperly tune them and not just jets, accelerator pumps, cams, discharge nozzles main body,bleed off screws etc they make great power! Bang for the buck take two identical cars give each person five grand one with efi one carbed who will win? With a carb you buy a good carb and intake, efi its t-body, injectors, maf, intake, well you know dam expensive that stuff is. Carb car will win. I also think a car with a carb vs. efi same power carb will always pull better on the top end. Just wy two cents.

I'd be willing to take that bet. It's not all about V8's here. I would love to spend 5k on hp alone on my FI engine in the Miata. I would get maybe 200hp to the crank on a carbed side draft set up. And thats pushing it. But having FI allows alot more room for improvement (in my case). That would easily be enough $$ to boost the everluvin shit outa my engine (which becomes very hard to do properly in a carbed set up). Including an AEM. Now that's just in this situation. Obviously there are other senarios that what you say would apply such as a late 80's gm 5.7 tuned port vs the same engine with a well prepped holley carb/intake set up. It is alot EASIER to make quick power with a carb there. But at what cost? Obviously driveability and efficiency can suffer (not saying it will). Ultimately, each situation isn't goin to need the same equipment nor yield the same results. They both have their advantages and disadvantages. But in alot of cases, the carb has seen its day in the spotlight.
