Until you start to get at least 3 feet of elevation, they are not required.

Sorry Alex, but I have to disagree. Not only does front end "elevation" uncover the jets, but G-force does as well. One does not necessarily beget the other. This coming from cars that 60 foot in the 1.15-1.20 range and are lifting the front only 6-8 inches, but even that is extreme as it does not take that much. Any car with a 60 foot of 1.70's or better will benefit from it. Even if someone put them in there that may not really need it, they will certainly not harm anything. Nothing worse than someone jetting a carb to the moon to overcome a bog only to find out they were uncovering the jets.
P.S.- Alex, just noticed the "professional manwhore" title. Please tell me you would pass on the giant with the size 24 feet!!

I have disagree too.

Jet extensions are cheap insurance. You do not want to run you engine lean because of the G forces that force the fuel in the rear bowl away from the jets.

If you run N20 or a supercharger they are a must..

Also,

On a stick car they seem to be more important than the slightly later hit of an auto. With the current combo c-4 & 408w the 850 doesn't have jet extensions at a 1.53 60'er. But the old 351w t-5 tranny needed them at 1.68 60'ers.
Also running the float level high in the rear bowl can overcome the problem too.

OK, OK, you guys win.
Stoker, just as soon as you start 60 footing in the 1.15 range, hurry up and get those real cool horsepower increasing jet extensions installed.

Hmmm, that tomato was thrown at me? Please re-read my post, I meant nothing disrespectful, nor that he had to hit 1.15 60's. Only saying that elevation was not the only reason.

Mike,

It's ok it was thrown at all of us. Maybe we didn't need the extensions with the stick car. but they seemed to help, and were cheap.

Alex is "da man".

SteveW

p.s.
Alev, BTW I got Dave's wheels today. Gonna have the slicks mounted on them tomorrow. Don't get to race 'cause of the Nationals at Infineon this w/e but they should help. Thanks,

As Steve mentioned, raising the rear float level will do the job in most instances. My Fairmont does go 1.15 60foots, or does 3 foot wheelstands, but it HAS gone 1.32 60 foots, along with 2 foot+ wheelstands I run a single 780 Holley vacumn secondary carb, with no jet extensions, but I do have the secondary float level cranked up quite a bit. I first uncovered the rear jets back when I installed a trans brake, & the car would launch, lay down, & then take off. I simply cranked up the float level until the problem disapeared. I`m probably 2 full turns of needle & seat higher than having the fuel just at the sight plug hole,but I`ve never had any problems the carb dumping fuel out of the boosters, or loading up when hitting the brakes after the burnout. It`s been set up like this for at least 10 years, with the auto,& the 4 speed, works just fine.

Throw some tomatoes at me, I love them!! Home grown preferred.

I don't know if it was the rear jets, the fuel system, or the fuel pickup in the tank, but right at 1.70 60', My Stang began to fall on it's face after the front end began to lift. I upgraded everything and it cured the nose dive. Just like baseball, it's better to have all your bases covered.

Cool pics! I like the Alex's Mustang better though Mike. Course I'm predjudiced. Also I would like to point out Alex is running a SBF no nitrous, while your buddy has a 540 CID BBC on the juice. I know the chevy is heavy but......gosh I'm thinkin the lil SBF is impressive! Just my .02 cents and No I wouldn't suck up to Alex for nothing I only suck up to my wife. LOL

They don't allow them in this class Alex. This is Limited Street that runs with the Outlaw 10.5 cars. 3100 pound minimum, true 10.5 tires, mufflers,.....and no wheelie bars. Makes for a great show, but gets VERY expensive. I have two cars I work on that run this class, and Bryan is a fellow racer. He had just gotten the ladder bars swapped for a 4-link. We told him we were gonna put a mobile home trailer hitch ball in his seat as a back-up for the 5 point harness!!

Never said it wasn't impressive Jerry, I like it too! 5.20's through the 1/8 mile on true 10.5 inch tires ain't shabby either regardless of the powerplant. That's why I like the class.....the tire is the limiter. Of course, knowing that this IS a Ford site and not chebbies.....

You need to jet down about 2-4 sizes and up the timing 3-4 degrees for starters in 5k feet of air.

Cool wheelstands. I like the bumper shot. (Crunch!) Also, it is not that I am so impressed with Chebbies. I like all hotrods.....American muscle that is. Anyhow, here is one of me getting about 4 feet of air after eating pork n' beans.....well, better not show that one.
Good thing I had my jet extensions!!!

By the way, not that this particular pass or wheel stand is so impressive by my little tiny 289 http://ihra.com/photos/2002/northern/epps/denasynko.jpg

but it had a 1.464 sixty foot time........

On the rear wheels? That is cool. Any wheelstand is impressive, heck that one is. Look at it again, the guy with his ears covered could've gotten up under there and changed the oil for ya'!
Think about the poor ricers though. They have to line up in reverse to get air That would be a b!tch going down the track....but ya know, if they watched Fast and Furious....I could sell THEM some jet extensions!! LOL

Actually Alex, I picked up 2 seconds in the 1/4 with my jet extensions when the Maverick was running 2.0 60' times. At least I think I did. They do go in the front bowl right?

Hehe, I wasn't brown nosing, just looking for a laugh. I'm more than happy to argue with Alex even though I usually lose

Haven't been to the track with the Cals yet. I'm currently converting the Maverick to cable clutch and going through the T5.

Well, I hate to disagree with Alex, but when my granada got down to running mid to low 1.50 60' times, jet extensions helped it. I have a playback tach with a printer interface, and I used to have acces to a printer so I could print the rpm from the entire run. Without the jet extensions, there was an rpm drop after teh launch. (and not the normal rpm drop from the convertor "coming down" from the initial flash, it was after that). Once I put the jet extensions on, the secondary drop went away. It was never bad enough that it was real obvious to me that it was there, but it did show up on the graph. I probbably could have raised the rear float level and cured it, but at the time I didnt think of that. Jet extensions was my first thought, and it it worked.

Hey guys....I never said that they wouldn't HELP. I have used them dozens of times on Holleys to cure a multitude of difficulties. I just don't think that every application needs them. As with all race prep, most is all test and tune.

Mike why are the tires a limiter? I know it's tricky getting small tires to bite but if you overcome that, they would seem to have an advantage. Yes/No? less rotating mass = less weight, wouldn't this be better? I used to run a 10.5 inch tire because that was all that would fit under my first car. I liked them just fine as long as the track was prepped well they seemed to bite good. Of course back then I ran allot less motor than now.
