I see posts where folks mention that they are tired of breaking things on 26's and like how things last longer on the 24.5's. In fact when I got my 25's Wil made a big effort to talk me outta the 26's (personally, I think he was out of 'em... ...lol...)

1) This "breakage" Is this or without a wheelie bar?

2) How heavy is the car?

I'm on 25's now, like it, want to go 26's. Dogbox, billet case and 5.9s should do it (in my minds eye). No idea. I have no practical experience with 26's. Is the whole 26's thing kinda like the axles thing? Where some guys can run 700whp on stock axles, and some guys can break 5.9's on 350whp (I broke one in the water box on a wet tire)? Is it related to launch/pre-load/driving style? Or just related to mathematical certainties with a calculated and predictable outcome?

What are 26's breaking that don't seemed bothered on 24.5's? My apologies, I'm sure this has been addressed, but 26 is to short a search term to get proper results.

Many thanks to those killing parts on 26's for their time and effort.

Short track is where you get your ets, and w 26s you can lay down more power.

 

so, to get to the actual question... what we're you breaking, and did you have a wheelie bar? Car weight?

 

Axles are the first thing to go. 5.9's will last a little while, but will break every now and then. The trannys don't like 26's either. Alot of this has to do with clutch setup as well. If you over do it on the clutch, it will shock the drivetrain too much. I spent the last year breaking just about everything in the drivetrain with the 26's. Most of mine was from improperly setup clutchless shifting. I think I have got it under control now.

 

i think most of the wheelie bar cars are gonna be lighter and have less breakage

 

The idea of the wheelie bar is to increase force. this force is achieved through leverage. Two cars with the same weight... the wheelie bar car has substantially more potential to break parts based on the intended use of the wheelie bar, which is to reduce slip.

I asked what would break. nobody reads... ...lol...

 

less weight = less force/stress , but i think when it comes to whats going to break on 26's its a matter of your weakest link

 

You break the same common things people break on 24.5s just more often. Axles, transmission components and differentials being the main parts that break on honda drag cars anyway.

 

*sigh* nobody reads.

 

that is the answer to your question, its kind of an obvious one, first you are gonna put beat up the clutch then when you upgrade that you are going to break axles, then when you upgrade those you are going to move on to the transmission.

sigh***nobody reads

 

That and also the REAL answer to his question is nothing. Because everything people break on 26's people are still breaking on 24.5s. the only difference being that the OP thinks if he gets 5.9s and dogbox with billet case he will be able to run 26's but these are the parts that are breaking for everyone else anyway.

 

I guess I was asking for advice from those with experience on 26's.

and was curious about the other questions.
1) With or without wheelie bar and
2) car weight.

Those pertain to the forces involved and influence failure.

 

s#@$ happens bro .......

 

nobody runs wheelie bars.....

and

all of the cars are 2400+ lbs


- take the winter off and practice "sliding out" that clutch foot.

 

95% of cars that you can get feedback from do not run a wheelie car and do not run at anything under 2400 lbs as posted above.

The cars that do run 26's and a bar usually have a beefier driveline and clutch setup, the key is to not shock the driveline just like with a street tire. Just keep that under control and things should go fine, as for ways to do that, just make sure the trans is in good order, the driveline is beefy, and as Danny said, you don't have too much clutch, being an 'easy' driver is key as well. If you haven't had a high attrition rate before, you are less likely to have it on the 26's over someone who can't run a 22 without breaking stuff lol

 

I've made about 50 passes on 26"s and never broke. Car weights 2500lbs with 3.9 DDS axles. Went 9.8's @ 150-155mph on most of the passes. To make the parts last longer you need to bring the boost in smooth and (like said above) "slide the clutch out"......

 

Well, how about this. Is you car set-up to handle 26's? Are you making enough HP to need 26's? Do you plan on running over 155mph? People who run 26's successfully, need 26's to ET/MPH. They all ran 24.5's until they hit that wall of engine rev's/short times/ET... plus you have the myth brigade speading breakage stories like it was them who broke. just understand in any car, any weight 26's will need more torque to spin (force x distance = tq).

 

i think this is probably the best advice when having to deal w/ 26's

 

What about carbon/carbon clutches? Or any other clutch specific componets people use and can chime in about?

 

It's easier on parts of course, but that human part can still do wonders on things lol

 

Yes, physically will fit 26's
Horsepower, Power to weight ratio 3.48:1
I don't want to go over 155mph, It's wasted energy, IMHO.
Cars already cert'd
has a chute,
have my License.

Not interested in hitting any particular wall, although I feel I'm there, +/- .3 on ET. I'm just going to go the 26's from the 25's, with some planning, So I'm ready by spring. Ain't gonna be cheap. Want to start working on it now.

I don't like to be broke down and I don't mind planning ahead. as an example I have 5.9's in my DD street car... Just trying to plan ahead.

 

I'll let John Force know it's wasted energy to go over 155mph.

 

Not sure it pertains to him unless he's looking to run a 9.60@150 in my Civic on a "Itty bitty" tire. Perhaps you could drop him a note and ask. It would save me a lot of time if you could do that, as I've been meaning to get after John Force specifically about that very thing. I'd drop him a note myself but tracking down his email and then writing it all out, and clicking the little button...*WHEW*... that's a lot of complicated work for this hillbilly. Plus, with my poor internet connection, I doubt my email would ever catch anybody going over 150mph... So, I'm thinking you're gonna have to let him know. Appreciate it, way to stay heads up on that. Glad John Force hasn't posted in this thread yet or we'd sure look silly.

..It does pertain to my goals though.

I don't want to go any faster, I want to get there quicker. It's possible it's not for everybody.

I'm not interested in trying to re-invent the wheel. Just use the wheel as best it fits my application based on the opinions of those that have ACTUALLY used 26's.

Excuse the excess typing, I'm hopped up on Butterfingers and left over Heath bars from the Halloween candy dish... I think I've eaten about 30 of 'em.

 

We used to run 24.5's and after switching to the 26's we've broken Tranny housings, Quaifes, Internediate shafts, Axles, Gears, you name it...

But, i would never go back to the small tire... lol

 

Bob, My experience says car weight and the mount of TQ the car makes. I had 26's on my CRX, but it only weighed 2150 with driver, didnt have issues. Also only made like 10 hits before the IC failed. But I was on stock axles, and transmission.
