I went to the local track today since the weather was good and cool (7-9C or 44-48F). I beat my old personal best. I did every run with the exhaust cut-out open all the way. I also had the spare tire and jack removed as well as the rear seat. Pretty much the same as my old times except I now have the cut-out and the front passenger seat was pulled for the previous runs. All runs were done by manual shifting the 2-3 shift (holding it to close to 7000 rpm). The one run that I let the car shift itself was a bit slower (15.1@ 90). Here's the slips:

1 .693 na 9.729 73.891 15.078 91.611
2 .561 2.269 9.735 73.975 15.141 90.717 autoshifted
3 .671 na 9.710 73.998 15.059 91.725
4 .619 na 9.702 73.989 15.033 92.004
5 .650 na na 74.668 14.949 92.783 both new bests
6 .789 2.267 9.692 73.958 15.024 92.041

8 .469 2.255 9.651 74.236 14.966 92.216 - (oops! Larry)

On the 7th run, the car was too cool and the tranny didn't shift fast enough and hit the rev-limiter briefly on the 1-2 and the 2-3 shift (keep in mind that I manually shift only the 2-3 shift).

I also used the new Accel blue air filter (panel not a cone) that Kirk was kind enough to supply me with at the convention. Aside from that and the electric exhaust cut-out those were the only mods I have on the car. If you want to count the rear seat removed as a mod go ahead. Also I've got the taller than stock 60 profile tires on that seem to hurt the 60' times slightly.

Went to the track today in search of a full interior sub 15 second slip. I came close but I fell just shy of a 14 second slip. Here's the results for those interested:

1 9.829 73.110 15.167 91.740 open exhaust

10 9.846 72.546 15.231 91.498 heat soak?
11 9.719 74.178 15.008 93.000 hit rev limit on 2-3
12 9.779 72.881 15.103 92.307 hit rev limit on 1-2 !!
13 9.736 73.760 15.052 92.580 open
14 9.810 72.969 15.179 91.179 pulled alternator fuse
15 9.788 73.563 15.109 92.499 put fuse back in

All runs were open and autoshifted except where specified otherwise. It appears that shifting the 2-3 shift manually helps the times. The open exhaust appears to help the times but it's not obvious (but it does sound awesome and I get lots of comments and questions).

The temperature was about 48F all afternoon and it was sunny for the most part. Air pressure was 30.08"/Hg as reported by www.theweathernetwork.com .

The relative humidity was 42%. The altitude of the track is around 300 ft above sea level. My current weight is 195 lbs.

Ian's been kinda busy this year - U.L.

Ron had some interesting feedback for Ian, maybe it will help me whup Scotty K by more next year!:}

A few very basic things to do:

Stage very shallow. Gives you more rollout before the 1/4 mile clocks start.

Do NOT hold the brake pedal down hard....only enough to get the launch rpm to 1,200-1,500 or so....no higher.

Play with tire pressure to get 4-5' of burnout.....enough to keep the engine rpm rising. Playing with high (40-45-50) then to low (30-25) will help this. If you can get enough wheelspin with higher pressures you are better off, as the 2nd 1/8 ETs will be better.

With stock RSAs I got my '99 to be consistently below 2.2.

I'm not sure why my car is faster than some. I think that the air is what makes the difference. I really believe that the car needs good air. Whenever the track is open and the weather is cold I go to the track. Unfortunately the tracks here are closed but I might head down to Atco (another long trip) later this month to improve my times.

I really haven't done much mod wise. Most of my runs last year were made with a stripped interior (ie front passenger and rear seats). This year I only took out the rear seat (55 lbs) a couple of times, the rest were full interior. I still don't have my UDPs installed. I've got a K&N air filter and an Accel Cool Blue filter (both panels in the stock airbox, and no not at the same time). My airbox is sucking hot air from under the hood (haven't finished step 2 of the Porterization). I try to run as low on fuel as I can. A full tank of gas can weigh over a hundred pounds. The lower the better, just make sure you bring a gallon in a jerry can.

One thing that I can account for the difference between my car and the other SHOs at Lapeer was underhood temperatures. I was pushing my car up the staging lanes or I'd keep shutting it down. I'd also keep my hood wide open till right before I got up to the front of the line. The other guys weren't doing this and I believe most of them saw there times get worse every run. Unfortunately I showed up late to the track because I was running around finding a tire shop to fix my flat that I got 25 miles after having the tires installed. Usually when I race I like to let the intake cool down enough so that I can touch it and barely notice any heat. That day I couldn't hold my hand on the intake runners very long (yeah I'm a wuss). In sub 40 degree weather it doesn't take long to get the intake cool. At Lapeer the temperature was around 57 degrees and we didn't get very long to run so most of my runs had limited cool down. Usually I wait at least 10-15 minutes or more to let the car cool down.

Speaking of cool down, at the convention this year, I let my car cool down for almost an hour and a half and my time dropped by 2 tenths and I gained a couple of mph. However, I did have the exhaust unbolted for my that run. Because the car ran some much better than it did in the previous runs I broke out even though I thought I had set my dial in to be pretty conservative. I ran what most of the Gen I & II MTX cars were dialing in. Obviously a long cool down helped me there.

The only other thing that I can think of would be the 'drive it like you stole it theory'. I drive my car really hard. Every day it sees lots of WOT action. Every on-ramp and plenty of green lights.

Well, it's hard to argue with Ian's results

Here's my slips:

   As you can see the car was running pretty consistent all day long. The last run was slow because there was only 9 minutes between runs. I had been leaving 30-45 minutes per run to cool down. I was the only person driving to the staging lanes with the hood up and I pushed the car up the lanes. I never idle the car in the lanes and when the car is running the heat is on full to suck any heat off the car.

As for the mods, the best one I've got is the Cermachrome coating on the runners and surge tank. I paid $200 Canadian (about $160 US these days) for the coating. See this page: http://www.magma.ca/~rld/krome.htm

Other mods I've got is the exhaust cut out bypassing the stock mufflers (would also bypass 3rd cat and resonator if I had them), SHO Shop power steering pulley (although it wobbles), K&N panel filter (might also be an Accel Kool Blue), hot air intake (entire saxacone removed), 225/50/16 Pirelli P7000 Supersports (light weight, shorter tires). Oh yeah, I also removed the SARC fuse and the daytime running light fuse.

Here's the slips for the opponents:

It seems that was at least one SHO made after 1995. I didn't see any V6 ATX's run anywhere near as fast and most MTX's weren't running that fast either. Maybe doughboy will show up next year and show me what a real SHO will run.

In other news I accidentally bought a Kenny Brown autographed Kenny Brown shirt. I was trying to run up the price and accidentally bought it. I also almost bought a model of the V6 engine. I would have stomped it on stage if I had won it. Why not? I stomped them earlier in the day at the drags.

Forgot to mention, I was using the 87 program from Doug Lewis with a mix of 93 and 87 (but mostly 93 I think) in the tank and I ran on the low fuel light for about 20 minutes before I even got to the track.

Also I just weighed myself. I back to about 190 on a scale that reads a little low. I guess I gained about 5 lbs during the week. I'm not sure if it was the copious quantities of beer or the fast food all week that did that. I must get that weight down for the fall but I've been saying that for years now.

7/24/05 - OFF LIST to Tim

This (above) deserves FAQ. I think he's got a thread from several years ago, add this to it and throw it out there. He was almost a full second faster than my best time, and most GIII's were stuck in 15.9-16.3 times based on heat soak, and just plain hot and humid. - UL

They kept "tuning" for lack of a better word, the computer and timing devices when time trials started. The lightning strike (not Tony's truck) really had them messed up. But I think all the ET's and speeds were accurate and printouts correct, like you say, by about 11:30 or so, and we extended time trials to 12:55 instead of stopping them at noon. Why 12:55 instead of the announced 1pm? I don't know, the track personnel made that decision, there weren't any cars coming up and it was hot. only one person goofed off till they were too late and got no timed runs, they had plenty of time to get runs in beyond the normal cut-off time.
