Since my last runs 14.21 @ 97.64 MPH and 14.32 @ 96.94 MPH I have installed cooling mods with water wetter, 3.5L programmed unichip, SSR comp 17x8s with bald Nitto 245/45/17 DRs, and have removed my VSA unit and installed required resistors. On the street, the car seemed much peppier and I had quite a bit more traction than before. Launched it and ran through the gears with no problems.

Tonight for the first time, I decided to do a long burnout through 1st and 2nd, staged and brake torqued my launch. Traction was pretty good, had slight wheel hop, but let off it for a split second, then hit it again and it didn't slip after that. Car didn't seem as quick as usual and it also spuddered twice at about 5000 something RPMs like it was hitting the rev limiter or VSA kicking in, then picked up again after that. Anyways, I only hit 14.34 @ 99.59 MPH.

Any ideas what the hell may have happened??? Trans going bye bye???

Damn all them mods and still not in the 13's. I will be so ashamed to post my numbers when I get them.

ghost_masterCL

did you bend an axle? with that much traction and power it could have happened...

have you even dynop'd it since your swap? you could be having serious AFR problems, or some other thing might not be working right causignt hese problems.

rtatsutani

Haha, too true. Ashamed is the word. I'm gonna post a thread on our hawaii forum to see what the other guys are running in our conditions and busted track.

rtatsutani

Think so? Maybe it bent when v-tec kicked in causing my car to bog from the resistance? There was vibration on my way home like there was a bubble in my tire. It wasn't constant but very noticable. I thought it may have been from the used rim/tire combo that I got which may have went out of balance???
Never dyno'd it yet. That's coming any day now. Ordered the AEM wideband a/f so that should be nice to monitor for personal use.

go check your oil level my 3.5 had alot of blow by so much so i would add a quart every 2 mos ,and the symptom you describe was my indicator it was time for oil...oil pressure/level is what engages the hi profile cam in the vtec system

Sorry to read that. I hope it works out for you.

All Mine

Was that off the bottle, btw?

rtatsutani

Yep, since it was the last day our track was open, I was very tempted to use a small 50 shot, but I really wanted to hit 13s n/a so didn't.

rtatsutani

I hope it is something this simple . I have not checked my oil since the conversion which was 3000 miles ago.

Alright, oil was fine, but there definitely is something wrong with my drive train. Took it out on a smoothly paved surface and heard/felt bad wobbling. Kinda like a slight metal grinding/wobbling sound. Maybe I did bend my axle and that bang was not wheel hop.

Mo power mo problems...

Damn, that axle nut is a bitch! Good luck

99mph trap means your definitely capable of 13's.

My car always feels slower at the track and never pull off good times until the end of the night. What was the air temp?

ghost_masterCL

if it does turn out to be your axles, then I would definitely look into custom stronger axles, either that or learn how to replace the axles yourself and always have a spare set of axles

rtatsutani

Conditions were 76 deg with 91% humidity. We've been raining for 40 something days straight which caused the higher than normal humidity. Normally we're at 70-80. If it is the axle, I'll def. look into stronger ones. Any idea how much parts and labor would be for replacing the stock ones?

rtatsutani

Ok, so cause of bog/no vtec has been diagnosed as low oil, checked it half assedly the first time. "Thanks typeR". Now hopefully the SSRs were just not balanced properly and the stockies will fix the bad wobble.

you're not going to 'bend' axles with your current mods. you really dont need to worry about that.

what viscosity oil are you running?

what heat range plugs are you using?

make sure the shop didnt install CL-P plugs, since every auto parts in the world says both the P and S use the same plugs.

i had the outter joint on my axle rebuilt for 40 bucks.

rtatsutani

Oil: Amsoil 5w-30 or 10w-40, I forget.
Plugs: Denso Iridium IK20.

if you can get 93 octane easily, i would try running 1 range colder on the plugs and see what happens.

edit: what elevation are you at over there? you should be seeing a high 13 easily, but vtec is HIGHLY reliant on oil pressure. i would drain it and fill it up with new oil.
