93 2.4l DOHC Shadow

Awesome! That 5th run was looking awesome(r/t and 60' and 1/8th)until you missed fourth! lol. Take the tubes out of the slicks, PERIOD! I am sure you will get kicked off the track....Probably be the first time you enjoy getting kicked out of somewhere!!! LMAO

Thanks man. So do tubes have any negative effects on things or is it just that most people don't run them? Right now they are tubed and screwed. The on aquired a leak because in typical DJ fashion I tried mounting my slicks myself..........and I failed. So I took them in, we pumped up the tube and couldn't find or hear any leaks so I figured it was OK. Well obviously it wasn't and the leak got worse. I will need to still run tubes until I get some 8" rims becuase the ones I have now I drilled out for the larger stem. I make the call when I get some new rims I guess but if they don't have any adverse effects I like the bit of extra safety that I was lead to believe they give.

did you wear the headphones going down the track?

nice job.

I had full intentions of doing so but when I hooked up the ol ear buds I wasn't getting much volume since my others are full over the ear headphones which block out much of the outer noise. But I will figure that out because I like knowing what is going on.

Most, probably 90% of us do not run tubes. You run a greater risk of cutting a tire or scrubbing the sidewalls over time without them. I've never heard of a new set with tubes leaking though.

Aside from that, another first timer on slicks and another great job. I'd say that run you missed 4th on was an 11.6 or 11.7 pass since you ran slower 60', 330' and 1/8th times and still went 11.8.

I didn't even look close enough at the missed gear run to notice that yet. Good call and that makes it exciting. Now to get some consistant 1.7 60 foots.

congrats! those are some nice #'s to go with a nice ride

Thanks man, it is good to finally have some go to back up the show.

If the tire spins on the rim with a tube the valvestem can get ripped. Thats why you see slicks bolted to the rim sometimes.

I run tubeless like most others... tubes add weight

Ya, I screwed/bolted my slicks on. At the same time I read a bolted slick will produce a better R/T since it won't slip on the rim. I have nothing backing that up, only a bit of internet reading. The concept makes sense though.

safety vendors often offer combination earplug/headphones. these might be beneficial.

i have the noise isolation ones and they seal ok but arent perfect.

JT beat me to it. Most of the FWD cars don't run tubes, I don't think you need to worry about spinning the slicks on the rims in FWD applications. Rear wheel is another story for obvious reasons. i think it is just useless rotating mass in FWD. Most of the TDer's running 10's even 9's run tubeless.......I'm no expert though.

EDIT: all of my runs were 1.7's with 23" tubless

Again, what an awesome fab job,

I don't run tubes either, more money to spend, lol.

Just have to check air pressure overnight as they do lose air.

[Turbo3Iroc]

Also as you noticed most wheels need to be modified to run tubes. And as far as I know there isnt a tube small enough for 23" though I think M&H has one for the 24.5.

But since you went through the trouble of drilling your wheels and opening up the valve stem, I would just buy a new tube.

[turboshad]

Maybe I'll try to get the car into the 10s with tubes so I can tell everyone if I didn't run tubes it would probably be a 9 second car

Dyno booked for next Wednesday. I'm curious to see what the curve looks like.

.:FoRuM56:. was out for the drag racing and took some video (thanks man) so here it is. He got my first 4 runs and had to leave so unfortunately not the fastest but it was still cool to see the car from outside the cab and it is another thing for me to study and hopefully improve on. This should be my last double post for this event. Sorry if you are watching both threads and have to see all this twice.

The first run.

The second run.

The third run and into the 11s.

The fourth run. I totally botched the stage so back to the 12s.

[Aries_Turbo]

nice runs dude!

[rx2mazda]

NICE DJ! Tune looks really clean all the way down the track. Did you lose at all? Just more proof that the Holset He351 is a really good turbo. Can't wait till you get it up in the 30psi range where it is happy.

[turbovanman²]

Love the 2 stage,

[turbokid]

Wow awesome runs!
More boost forsure =)

[rx2mazda]

Love the 2 state,

WTF is a 2 state?

Yeah, just fixed it, 2 stage/step, lol,

I'm off to the dyno tonight. With the 1/4 mile speeds I'm expecting some high 300 to maybe low 400 numbers. I went out last night and put in a bunch more timing and still no knock. It will be interesting to see the difference between the 1/4 mile tune and the new one. But really as long as I can drive it home I'll be happy

That's the right attitude to have. Frankly, with the times you posted in the real world, you hardly need a neat graph to go with them IMO.
