Default DERTY goes 9.88@138!!

Just got off the phone with Steve, first round qualifing for NMCA 10 second index at Stanton.

He kinda over shot a little

Had it on the dyno last night at Detroit Speedworks for the first time with the new direct port system. Word is he picked up 150 RWHP on the 200 hit with a pig rich 10.5:1 AF, the unforgiving mustang dyno no less.

First full pass on the bottle, off the T-brake.

1.37 60'
1/8: 6.3 something at 109
1/4: 9.88 @ 138

Guess it toted the wheels pretty good

not too bad for a 382 all bore on a little 200 shot.

Michigan should have some quick cars at thunder this year

Jelly, Tim, and I were at the track today and saw the car we just never saw Steve by it.

Too bad we missed that pass, would have been nice to see one of the locals run well.

Nice short time there Steve-O

Ya, good run there Steve. I got the call late last night, but could not get ahold of you.

Lets see the video.

Well, I made it home in one piece. The car made it all weekend with no serious hiccups. Needless to say I was stunned. My honest expectation on a 200 shot would have been about a 10.30 or so.

I took it over to Detroit Speedworks Friday and basically had it on the dyno all afternoon. We did some motor pulls and corrected the tune since I swapped to dual Borla XR1's and the Turbo 400. It looks like I cleanly lost 50 horsepower over the T56, but we also managed to gain an extra 20 horsepower with some simple adjustments.

After that we spent hours chasing down issues with the fogger. As the car sat, not running I could activate the WOT switch and the solenoids would fire. However when we got the car running it wouldn't fire. I chased that down for a long time checking the nozzles, lines, etc. They all flowed fuel, etc. Finally I looked at the POS WOT switch that came with the kit and decided to just take that out of the picture. Once I did that it fired right up and about an hour of adjusting the timing we had a good safe tune into the car. Managed to get a little over 150 more to the tires. My converter flashes at 5200 so all the pulls only picked up everything after that. The horsepower was a straight line all the way across the RPM band and the torque was right there with it. I was very impressed

Allright, now that we got all that covered here's how the racing went. Off the trailer I wanted to just make an easy 1/8th mile. I set the delay timer off the transbrake to .50 seconds. I clicked the car off about 100' short of the 1/8th and here's the slip:

60' - 1.498
330 - 4.132
1/8 - 6.394 @ 103.47
1000 - 8.626
1/4 - 10.893 @ 93.13

I went back to the pits, and they closed the lanes for time trials. During my first qualifying pass I decided to just leave off the brake. Here's the timeslip:

60' - 1.375
330 - 4.063
1/8 - 6.303 @ 109.70
1000 - 8.247
1/4 - 9.88 @ 139.05

The car yanked the wheels about 2' and carried them for at least 50'. It picked them up smooth and set them down just as smooth. Straight as an arrow right down the track. I knew it was a fast pass, I hardly remembered seeing anything but the finish line. When I got the slip I just about died and had to check the car number three times to make sure it was mine.

I knew I had to back it down so I put a .50 second into the timer and clicked the kit off 200' short of the line and ran a 10.056 @ 132.56. My 60' was a 1.497 compared to a 1.498 during the first run that I delayed at .50 seconds. The last pass of the night the track started going away. I ran it exactly the same and only went 10.080 @ 136.65.

Since I was activating the solenoids while holding the transbrake (I have it wired so that the transbrake cuts the solenoids off, like most do) my reaction times were terrible. I ended up getting one of the new TPS switches from NX at the track. I wired that in, but didn't have it set right for the first round of eliminations. It didn't come on until well into my 60'. We checked it in the pits and it was flaky. Sometimes it would come on, sometimes it wouldn't. After that round we made some adjustments to it and figured out how to get it to work. There's a small screw in it that we didn't see at 12:30 last night when I finished it up.

Anyway, I'm going to hit the track at least three times this week and get some full runs in a couple times. I then have to dial it in for a 10.0 index race on Saturday.

Needless to say, ARE built me one helluva bracket racing nitrous motor. Rossler built an awesome TH400 for the car and Neal Chance really nailed the converter for the car. I'm really impressed! I'd also like to thank Jay and Amber Billingsley as well as Steve Spohn for supplying me with some great suspension components, brakes, wheels, etc.

After this weekend I'm doing nothing but putting the car into kill mode for Thunder. I'll be sending the car back to the chassis shop for the updates to the cage, I'll get it back and we can get it certed and get some license passes done. I'm glad everything has finally come together. It has far exceeded my expectations!!!! I can't wait to see what goes down at Thunder.

BTW, I have no idea what the DA was here and no I don't post horsepower numbers. But you can go find a calculator and figure it out! The car weighed 3525 with a full tank of gas during the 9.88 pass.

Here's the two track photos. The one on off the brake is from the other side of the track. The starting beams are well to the right of the divider there. When a friend of mine gets the video converted, I'll post it. It might be a couple days. I'll get it up when I can.

Sweet run and pics. Do you have before/after times with the T56/T400 swap? I'm planning to swap next week and I'm just curious.

Unfortunately I can't give you a fair comparison. I honestly think my T56 was broken at Bowling Green when I ran it the first time. It went 11.80. I want to caution you that I never ever managed to get a good time out of the T56 before I nuked it.

With the TH400 set up with a 4000 stall converter setup to spray out of the hole with, I can run 11.3-11.4 all day long without breaking a sweat. It's basically a dog on motor at the track. It's damn wicked on the street though! Highways tend to suck though, nothing like 3500 RPM that doesn't lead to lashing your valves every time you get home. As I found out though, it's sweet as hell firing out of the hole! And it shifts through the spray so smooth I was amazed!!!

Thats awesome

Those NA times aren't bad for a nitrous setup. With the right gear/tire/converter/tune for NA you would have mid 10's no problem

Cheers,
Chris
