Anouther let down. This time in the 1/4 mile.

l was busy for opening day for Woodburn drag strip yesterday, but there was racing today. So i went down there. It was pretty cold, with a 5-10ish head wind, and two rain delays. Most of the serious racers (points people) where saying the track was pretty green, and slick. Wich it was.

I've came to the conclution that n/a 2nd gens in general are pretty slow. My best time was a 15.1@94.8mph. 60ft times where like a 2.5 or 6. Can't remember. Just like everyone else on this board, launching was the biggest challenge on a slick track, with bald tires. They are'nt completely bald, but down onto the wear bars.

I only had the chance to make a couple runs. Maybe i could have done better. I don't know. I'd like to think so, but when it comes down to it, i did'nt.

I still plan on getting the s-afc tuned on a dyno, but after that i'm probably going to stop building the 2nd gen. Unless i find some serious hp in there, wich i don't count on. There will be some new tires in my future, but thats just for safety.

Overall, i had a great time, but kinda down about the results. CJ

BTW, my brouther in his mustang ran a 12.7@120mph on thin little street tires.

My other brothers SHO taurs ran a 15.5@90.

What's done to the mustang? (I know them pretty good)
Don't compare yourself to a live rear axle car. Its built for straight line performance. Try him on the corners, and he'll be fucked.
Mustangs take a lot to make them handle (and the cobra IRS is a stepp in the right direction, if they only made beefier half-shafts...)

The mustang has a (I think) 347 in it. Blower running 10lbs of boost. Sorry don't know what type. Full exaust, with X pipe, cyl heads, cam, sds injection, etc. etc.

The car as it sits is untuned. But he was'nt grabbing traction until 4th gear.

He needs to install his gears, put some slicks on it, and get the injection system tuned in. Then it should be pretty quick. CJ

HOLY ****, that is a bad time. He should be running high tens, low 11's.
A stock 5.0 with 10psi of super can run faster than that.
He needs some serious tuning done, or needs to learn how to drive.

WOW those MPH's looks way high compared to ET... 2.6 60' times? Did the track get the VHT and the waste oil confused again?

That indicates bad 1st gear performance.... bad low end lorque, or low traction...
I have crappy low end torque. and my 1st gear kindof sucks for some reason.
My best time (before my S-afc which made a big diff) was 14.54@99.7...
High MPH... I also can't launch consistantly.... yup...
Well.. 15.1 isn't bad.. but you have a lot of mods don't you??
I would start looking for a problem... you already know you are running rich, you should gain 20 HP with the dyno tuning if you are at 10:1!!!
What about ignition??? Maybe you aren't getting a good burn, that would show up in the exhuast probe as a rich mixture too..
Maybe your compression isn't perfect??
Must be something somewhere..... a ported engine with dual exhaust, and no emmisions should be running a bit better...
Maybe your AFM is out of whack??? Too loose??
Who knows, but there's got to be another second less in ET there somewhere!!

To be honest, the car was going faster, and faster the more i adjusted the s-afc, and i only got 5 runs. My motor is realy a very mild port. It still has a stock idle, and will pass emissions. I still have all the emmisions on my car minus cats too. Bolth coils check out. Also i noticed that the higher i shifted it at, the faster it ran. As when i shifted it at 8,500 i ran my fastest mph.

As far as the mustang goes, its just wat to much power for the amount of traction the track had. I mean he would be blowing the tires off in 3rd gear, just rolling into the throttle. Even my 2nd gen would loose traction shifting into 2nd gear. It was pretty slick.

Pee-Jay, there was a couple new guys working at the track this year. Maybe they did get em confused??

Once i get back from my honeymoon thing, i plan on going back. Hopefully the track won't be cold, and there won't be a head wind. If i can't break into the 14s, then its time for nawssss man We'll just have to wait and see. CJ

When I took my stock 90' GXL down I only ran a 16.9 granted I didn't have nothing done to it (this right before motor blew) but I did by that RX for it's strait line ablites.

My cousin has a Mustang that runs 11.76 on street tires and it is all motor if he could get the thing to hook up it should run low 11's and his car really, really sucks in the corners.

Ack, If I wanted a Drag only car I would buy a muscle car! but I bought my RX7 for the turns! Sure acceleration is great and all, and we all want more of course. But I find it much more funner flying around a roadcourse or an autocross than "1 2 3 GUN IT"

Remember you are comparing a small import to an american muscle car. Take yer rx and your brothers mustang to a local autocross and then compare

ShambldeBK....10.1 in the 1/8 would amount to 15.6 in the 1/4....Good Job.....Thats not stock was it?? I personally have seen a stock one get 10.2 with my own eyes but nowone really believes me. Moded ones that got a 9.9 got a 15.3. It varies.

PPnos. Dont be so down on N/A power. U should be hitting low 14s. U just suck at racing...hehe Get it tuned.

15.1 isn't slow and a SHO Taurus is quick for what it is. The SHO package is the performance engine.

2.5 or 2.6 for a 60' is your problem. Probably due to the track conditions- your MPH should get you into the 14's if you drop that 60' down to a 2.1 or 2.2.

The 60' is the key to a good ET, and your 60' is blowin goats. Get that 60' time down to 2.0 and tune your car and you should be gravy...........

Hey CJ,

What flywheel do you have on your car? Light aluminum ones aren't very good for drags. I've got a 17lb steel one on the TII and it seems to launch pretty good. I've got some Hoosiers on a couple TII wheels that you could throw on there. A little burnout and they get pretty sticky. That should help you get those '60 times down. Do you slip the clutch or dump it? What clutch do you have in it?

I got a 1.982 '60 time on my TII, possibly could have done a little better if I kept running. 5 runs and I got a tiny bit better on every run (track was warming up).

What is your best '60 time on your FD?

Maybe we can meet up at Woodburn sometime. Also try putting on stock aluminum spares in front, it'll save about 40-45lbs over 87 TII wheels.

Later,
Jeff

Hey guys, i'm not even trying to compare my FC to my brothers Mustang. Shoot, my FD would'nt even come close to that mph.

Jeff, i'm running the stock flywheel, clutch, and pressure plate. I tried to slip the clutch, but all i did was manage to make it smell realy badly. So i tried dumping it a couple times. If i launched it at 4k, it would bog. 4,500 and it would spin. On my 15.1 i dumped it.

My best 60' in my FD was a 2.0 on street tires. That was last season. Before the mid pipe, y pipe, m2 intake, ic, and i was running stock boost. Basically all i had done was a down pipe, and the racing beat intake.

I'd love to buy them from you, as with a battery tray for the FD. If you want to hang on to them for a month or so, we may be able to work out something. I'm doing the wedding thing this weekend, and honey moon next week. After that we're moving into the new house around the 16th of April.

Please let me know how much you want for them. Even if you want to keep the rims.

As a indication of how slick it was out there, the funny colored cobra mustangs with slicks (bolth of them) where only managing low 14s. One guy had an exaust, and the other was stock. But bolth had slicks. What should they be turning?

Dude, don't be down. Almost 95 mph in the quarter is a nice mid 14 second pass. Those crappy 60' times are what killed your ET.

Hey Cj,

2.0 is pretty good for your FD on street tires. My best in my FD with auto-x tires is a 2.005. I actually got pretty close to that with the stock clutch, that is when I met you. That clutch was almost worn out, it slipped just a little on the launch and didn't let the wheels spin. When I got my best '60 times in both my cars I slipped the clutch just a little. You probably should upgrade the clutch in your n/a since it is obivous that you are putting down some really good power with the 94 mph trap speed.

I'll sell you the Hoosiers cheap, they'll fit your FD too for the Medford event if your coming. I'll hang on to them, no problem. I probably have 4-5 sets of wheels and tires sitting in my garage anyway.

You never told me how that IC fits?

Congrats on getting hitched!

Later,
Jeff

The ic overall is realy a nice setup. Its a pretty tight fit, with the stock battery tray. That why i'd like to buy a battery tray from you. The only down side of it is the silicone couplers could have been a little longer. I'll get some pictures soon, and send them to you. Later, CJ
