Apexonyou is still my hero!

Damn that's good. Congrats man!

What tire/wheel combo were you running?

Edit: Still on the 4.10?

Used three year old 225/50-15 used BFG drag radials on Enkei Wideopens(15x8, +20). I really need flares, they stick out a little. I modified the upper control arms so I can run near zero camber when at the strip. The +20 offset makes it even worse. Had to raise the car almost 2" to keep it from rubbing.

Yes, 4.10's with the 6sp.

Impressive. I have to ask: you mention in the first page of our build thread that you autox twice monthly plus daily driving and track duty. Has your entire eBay setup held up to that all along?

Will continue reading your build thread...

I don't autox nearly as much as I used to. I have a short commute but I still DD it when I don't have to use a truck. The miles that it does get are pretty abusive, not a whole lot of highway cruising. It occasionally goes off road and tows trailers too. I don't do real track days, just a handful of unique events at the semi local track.

The car does no one thing great but is a blast to drive and has working A/C. I feel that I've spent the least amount of money to get reliable power yet be conservative enough to make a worn out engine put out decent power.

I don't want to disclose what I think it puts out(flame suit out being repaired) but the weight of the car going down the track was 2528lbs and the trap speed was 118.39mph. Plug that into a calculator and it returns true whp per pure physics.

You and Apexonyou. Were basically the inspiration for my ebay build, and mine is still kicking I cant wait to get mine to a 1/4 mile track.

Your Mph is incredible! Keep doing whatever it is your doing, a little more boost and a 1.8 60" and you'll be in the 11's!

So awesome. Is your timing map in your build thread? I'm going to look through it now.

I don't think the timing map would help anyone. My timing numbers aren't accurate. The crank pulley/key/keyway were permanent Loctite/JB Welded on in '06. There is at least a +/- 2 error in that alone. The timing belt probably has 100k on it so I don't know what that does. I'm also running E85.

I backed the timing off 2-3 last year to try to make the motor last longer. There was a noticeable drop in power so I think it's very conservative.

Very impressive for how many shifts are involved. Seems like a 3.9 would do you good?

<----knows nothing about drag racing.

more like a 3.6
but then his trans would call it quits shortly after I bet

This is very impressive. Only other person I've seen do this on a stock engine/trans was a local guy with a 94 running a gt35r on e85.

He blew his engine just a few weeks ago. Best pass was 12.0 @ 118 IIRC. Stock engine stock trans.

Apexonyou managed 11's on a stock motor and a log manifold. 5spd, though.

yeah. gutted car though
and his best trap was 115 iirc
so not as fast, but moves out quicker due to lighter weight and better driving

Apexonyou did it on street tires too! He had launch control and laid down a 1.78 60', iirc. I only did a 1.94 on that run. He set things up perfectly.

The funny thing is that It's still going pig rich and hitting the boost cut before the traps so there is actually more power than what the mph indicates. The track was too busy and I only got two real runs so no tuning happened.

I've been thinking about a diy traction control method that is ugly but effective. This would be particularly helpful on the street. I pucker when I get wheelspin while passing gravel trucks on a two lane highway - in fourth gear.

I ask, because I just wonder how much boost he was running and how his stock block didn't VTA on his first pass.

Great run, really impressive on a stock motor. Are you having to shift to 6th before the line? 3.90's would definitely help that.

3.90's would help. The last time at the track my trap speed was 115-116mph banging on the 7300rpm rev limiter. I raised it on my last run and I trapped at 117.8mph. This was on the shorter 205/55-14's.

This time I started with a 7500rpm rev limit and had taller tires to help the gear ratio and traction, 225/50-15's.

Fifth through the traps. I've contemplated shifting to 6th but didn't have enough runs to test it out. I think it would hurt ET but give more mph, maybe.

There is a lot more ET in the car, I just need to figure it out.

I know what you mean, but that pig rich condition can actually be helping your torque curve a little, believe it or not.

What were you thinking of for traction?

yeah, never posts tho
I posted up his dyno runs and quarter mile runs a bunch of times though.
