Default 400hp + stock axles + 24.5's = A tow home from the track

Ok so I have a 92-5 civic coupe
built/bored b16
b16 tranny
quaife lsd
itr fd
24.5x8x13 MT on lenso's @ 12lbs of tire pressure
Stock Axles
making around upper 300's possibly 400whp on 17psi
Cars last run was a 12.0@115 on 14psi on 22x8x13 MH's@ 10lbs of tire pressure

I recently went to the track with the new 24.5, did 2nd gear burn out. Went to stage and preloaded as best as I could without it pulling the car. I built about 10psi off the antilag and was at about 6500-6600rpms. Went to take off and the axle snapped into the passenger tranny side. I replaced the axle but my question is should I try preloading with the ebrake? With my old 22x8x13s I didnt have to use the ebrake at all and was cutting consistant 1.7-1.8 60fts but was running out of gear in 4th. Is anyone else making around 400 or so with stock axles on these same slicks having any launching problems?

yes u should always pre load with the e- brake should help if u didn't use the e brake last time, thats why u most likely broke an axle cause u didn't use the e-brake. hope that helps

Wait, so you were trying to preload without using the e-brake?

What i do is put the car in 1st, pull the e brake all the way up and hold it there and use the clutch to more the car forward to stage.

Once it stage, with the e brake all the way up, i let the clutch out as much as i can without having the car move forward.

Once the 3rd yellow light drop, i drop the e brake and feather the clutch depending on how it feel.

when i was making 380 whp using 24.5 slicks the stock autozone axles lasted longer than the top of the line gator axles. i dont know how you preload without the ebrake. especially with the antilag...

I ran stock axles(mid-high 10's) for over a year and never had a problem...guess I was just lucky. lol. Must be some good sets and some bad.

good times none the less.

ok ill try that but it seems like the antilag wont let it build boost if the clutch isnt in but to a certain point. Im hopefully going out to the track this weekend and if the axles hold together should be well into the 11s.

I would feel where the car wanted to leave, and keep there then let the clutch out firmly, but smoothly and on a stock GSR gearset with DSS stage 5's I was in the clear all the time.

But I do agree with stolenteg, I just never took the time to do it haha</TD></TR></TABLE>

Feel like an idiot but what does "sidestepping" mean???

raise the launch rpm and lower the tire pressure. you need to spin the tires in order to keep the axles alive.


ive ran9.8's & 158 on stock axles on 24.5x9x13. if your on stock axles, ALWAYS bring a spare set. a 10 min axle change is a lot easier/cheaper than a tow!


used oem honda axles work way better than any of the napa/autozone "new" axles.

preloading saves axles imo...

Thanks Joe, yea Im going to bring an extra set when I go just incase. Im going to try the antilag at 8000rpms and 10psi off the line instread of the 6500rpms and 10psi I was trying. Wouldnt I want to keep the tire pressure higher to get it to spin a little off the line?

Thats a good idea. Also try preloading more, and with the e-brake this time. The increased RPM from the higher antilag may help out with building boost a little better, so if you let the clutch out a little more while on the e-brake, you mite be ok. (as far as snapping another axle)

Ive seen some of Tony1's vids where he preloads so far with the clutch and e-brake, you can see his rear end of his Integra squat!

when you guys are talking about stock axles are you talking about oem honda axles or auto parts store axles?

i agree 100 percent Joe. try 7-8psi in the slicks, and more rpm. and always bring an extra set of axles.

not sure how you can preload without using the ebrake. the car would start moving.

How heavy is your car? I ran an 11.9 @121 and was making about 340 whp, in an eg hatch. I was just thinking that 115mph seemed kind of low for a trap speed? But i guess i dont know, by all means im not calling your car slow, maybe its the tq difference between a b16 and a b18c? And i did run stock axels on that pass i made. they were oem honda, which someone already stated seem to hold up better than any aftermarket napa/autozone stuff.

went to the track yesterday I made 2 passes on the 24.5s preloading but had horrible 60fts. Went 12.3@115 with a 2.0 60ft , then a 12.4@116 with a 2.1 60ft. I was preloading using the ebrake. They decided they wanted to reprep the begining of the track and I was the first car to run. In the back of my mind I knew something bad was going to happen. Went for my next pass, burnout was fine and went to take off on the line and snapped the driver axle into the halfshaft. Im getting frustrated with these slicks, I never had this problem with the 22s but I had a problem with running out of gear in 4th with those. my 1/8mph did go up from 90mph(22s) to 92.5(24.5s). Seems like its hard to get the slicks moving but once I do they are fine. I was also running between 12-13psi of pressure in the 24.5s

i run 25's on my 4dr integra (2700lbs) on lenso's, with a tilton twin disk, i pre-load slightly (twin disk doesnt like it) and last year i broke an axle every time i went to the track....i put in innovative 95a motor mounts, and have made 12 passes so far this year with not one axle broke.

i run my slicks at 8.5psi, cut 1.70 60 foots, launch at 7500 on 10psi of boost...and i run 11.6x's at 120-122.

in my experience pre loading, and proper clutch engagement, and good solid mounts are key to axle life.
