Glad you got in the 11's, also glad you admitted you gained nothing with the gear change. Next time listen to us LOL. You are trapping well, I think your car has another tenth or so in it. What was the DA?

DA was just about even sea level +/- 100 feet all day, so the weather was consistently good. 2 months from now, the DA will be 1500-2500' above sea level at our local tracks, so I have to enjoy the 11 second time slips while I can!

While I didn't gain any ET with the 4.10's, I still love them on the street. Car is much more lively and way more satisfying to drive. As for fuel economy, I rarely drive on the highway (my mpg took a hit there), but my in town mileage improved a couple mpg since I don't have to use as much throttle to get the car moving with the 4.10's.

Can't say enough good things about Mike Rousch's tune. The driveability is awesome and it went quicker at the track with more to come once I datalog for him.

To many variables, track prep, DA, etc, etc. I think he is close to where he should be for his mods.

Track prep was not so great and the track undulates a bit past the 1/8 mile mark making for a rough ride on occasion. For comparison, there were 6 Coyotes at the track last night. My friend Bob's '12 GT AT is Procharged (630 rwhp on a Mustang Dyno) and he ran a traction limited best of 11.59 @ 123 (2.0 60' times). All the rest of us Coyotes were NA and I was by far the quickest of the bunch. The others were all running 12.70's to 13.50's with trap speeds in the 105-110 mph range with various stages of mods/tunes on each car. My 11.90's @ 115 was clearly dominant. I beat a '10+ GT500 very badly, as well (by a couple hundred feet!). About the only "street" car there (not trailered in) that was consistently quicker than me was a Nissan GTR that was running 11.20's. So, a better track with better prep might yield even better numbers. I'll be running at our other local track later this month (Pacific Raceways - formerly known as Seattle Int'l Raceways) and that track is much, much nicer with top notch track prep. I almost always run quicker there, so we'll see.....

Agree on Mike's tunes. I had Steeda, which sucked, Bama, which was just okay, and now Mike's. The difference was very noticeable.

With basically 0 DA, you can't ask for much better. I've never run in DA better then 500, usually deal with 1500 or so.

I'd really expect a better 60', that's the one thing the gear does improve as long as it hooks.

100% stock engine, 100% stock exhaust, 100% stock suspension, heavy 3800 lb car. 11.5's will take another 40-50 hp to achieve.

I'll split the difference. Fine tune the tune and I'm calling it a 11.7 car. Other autos are getting 12.2 in good air with the stock converter, street tires, off road pipe and a tune. With your 60 there's more there than a 11.9.

I'm contemplating an off road pipe, but I'm in a California Emissions state so my exhaust is 100% intact still. 11.70's sure would make sense in my car with an off road pipe.

Brian how often do you need to get smogged? After having taken the factory H off and put the offroad one on the car - it's a piece of cake. Probably take you 30 minutes with a little help.

I have one for sale, a Lethal that was on member of my clubs car for about a year. I was going to instal it and decided against it. If my car saw more track time I would do it for sure, but the side effects turned me off. $200 plus shipping, but I do have an interested local buyer. No payment yet though...

Hope I can jump in here and not hijack too bad and get a little advice. Maybe some of you more experienced guys can offer some tips?

I'm running a Circle D 4C with 275/60/15 MT drag radials, 3.15 gear, AED tune,single piec aluminum drive shaft and a lethal off road H pipe. Best i can get dead hooking are high 1.7 60' times.

Are the 275/60's too tall for the 3.15s? Best ET is a 12.02 @113.8 at US131 at Martin yesterday. DA was about 1500. I will admit this is a heavy car at 3900 with me but I expected solid 11's. When I launch the car it almost feels doggy until a little ways out.

Just loading the converter a bit, then leaving on last yellow. That was the best ET. Leaving at idle was about a tenth slower. I should have tried getting some more rpm before launching I guess. Running 16-17 psi in the tires.

I tried a variety of launches with my Circle-D 4E stall converter and found that now my car traps highest by holding a lot or rpm's against the brakes at the starting line (leaving off idle was the slowest).
