Asphalt results "2006"

[Master of Faster]

There was a little bit of a crosswind, sometimes a light headwind. When I ran the 9.7 is was pretty calm. At the time I ran the 9.7 I thought it was just an OK run, it was clean at least, but the sled didn't hook the greatest, but I didn't even do a burnout, just pulled up and went. Next time out I think I'll up the engagement and do a burnout to see if it will leave a little harder. Leaving at 3800 it takes a split second before the turbo spools. I never did really make a clean run on 10lbs, but the clutching was so far out at that boost I doubt it would have broken into the 9's.

WIR 7/7/06 Temp 84, with 42% humidity, and a barometer reading of 29.30
Sunny conditions, and a headwind of 15-20mph all evening, till the humidity jumped up to 80%.
Tom, (MrSled) and his 2 brothers, Bob and Jr., along with Rich from Richmotorsports came down to watch the night of action. Great to see you guys again, and hope to have the SRX done so Tom can take the Apex/Attak for a rip down the track with me.

The great debate is over for me, as I tried a cold bottle against a hot bottle, and the results were just the opposite from what I would expect. Tom was amazed also to see a cold botlle get a quicker time than the hot bottle.........Yes, you heard me.

Now, this is with my system from Barry, and cannot be compared to the other systems, cause I cannot say what effect it will have on other brands, just that I have proof of what I have encountered with my sled. All nitrous runs were stabbing both the throttle and nitrous right off of the line.

1st 3 runs were with a hot bottle at 93.5 degrees, from being in the trailer all day in the sun.

1st run - lane 2, reaction .047
1.489 60ft - 6.475 1/8 @ 107.909mph - 10.264 1/4 @ 126.234mph

2nd run - lane 2, reaction .147
1.501 60ft - 6.377 1/8 @ 108.722mph - 10.155 1/4 @ 126.047mph

3rd run - lane 2, reaction .172
1.489 60ft - 6.679 1/8 @ 99.155mph - 10.840 1/4 @ 114.034mph (ran out of nitrous)

now the cold bottle at 45 degrees for the next 4 runs

1st run - lane 1, reaction -.107
1.484 60ft - 6.362 1/8 @ 107.472mph - 10.126 1/4 @ 127.215mph

2nd run - lane 1, reaction .078
1.493 60ft - 6.396 1/8 @ 109.226mph - 10.189 1/4 @ 126.528mph

3rd run - lane 1, reaction -.039
1.501 60ft - 6.477 1/8 @ 108.790mph - 10.234 1/4 @ 127.779mph

4th run - lane 1, reaction .021
1.497 60ft - 6.545 1/8 @ 103.725mph - 10.517 1/4 @ 119.770mph (ran out of nitrous)

As the bottle warmed up between runs, the times got slower with the 3rd run almost going over he centerline, so I lifted a little bit. This was unpredicted, as it should have been the other way around, but for a .03 difference from the best of 2 bottles, this will never be an issue for me again.

Congrats to Ken with his Skidoo Crankshop 1000, as he ran (2) 8 second passes on Friday. 8.991 and an 8.968, both at 143mph!

Wisconsin International Raceway - 7/8/06
temps in the mid 80's, humidity 50%, and you guessed it........headwind of 25+

1st time run - lane 2, reaction .208 (sleeping)
1.493 60ft - 6.926 1/8 @ 95.071mph - 11.243 1/4 @ 110.305mph

2nd time run - lane 1, reaction .049
1.499 60ft - 6.910 1/8 @ 95.743mph - 11.196 1/4 @ 111.442mph

1st round - lane 2, track temp 138, reaction .181, dial-in 11.27
1.511 60ft - 6.972 1/8 @ 94.343mph - 11.305 1/4 @ 109.894mph
Won round 1, due to other opponent Redlight

2nd round - lane 1, track temp 122, reaction .057, dial-in 11.28
1.499 60ft - 6.928 1/8 @ 95.682mph - 11.235 1/4 @ 110.685mph
Won round 2, due to other opponent Redlight

3rd round - lane 1, track temp 109, reaction .107, dial-in 11.24
1.509 60ft - 6.947 1/8 @ 95.178mph - 11.271 1/4 @ 110.418mph
Lost round 3 due to oil on the starting line. I was pointing at the oil spots, and they took a mop, and made it worse. I hit the throttle early, and still had a sleeping reaction time. All I could do is go for a ride. Rules call for no dial-in changes after you cross the redline from the staging lanes. @#$%^&!!!

Well, still in 2nd place, and only 2 points behind the leader.

Mohawk pic is for monker.

tough day at the shootout for me. the day really dragged on. If there was any doubt that I hurt the motor last time, I removed all doubt this time. Looking in the in #3 cylinder you can now only see 2 of 3 intake valves. Happened second round of bracket elims. Hit the gas at then line, then shut her right down. Stopped on the track before 1/8 mi.

I'm done for the year.

Mike made a good showing in the quick 16. I'll leave the details of that for him.

Keep up the good work guys.

Terry thats weird how the cold bottle went faster, everything I've ever been told pointed toward heating the bottle. Do you think it possibly had something to do with not having enough fuel for the higher pressure or just because the NOS was warmer?

Sorry to hear about your motor Monker, our turbo motor went down this past winter, deffinitely sucks.

 

[NOS-PRO]

I have always thought that also, as the old system components I used, had to be warmer to produce the pressure needed. But not in this case as the bottle got warmer between runs, the sled ran slower, with no other changes to the sled. Burnouts all the same, 60 fts. within .01 of each other. If this was true, (which I was also guessing on), the machine should have never run faster than the warmer bottle runs. But, I wanted to know.

Allow me to explain why. Hold your hand over your mouth and blow really hard then take your hand away. You will expell all your air very quickly thereby leaving you breathless and in need of a big gulp of air. The same thing happens with nitrous. When the bottle pressure raises, you get a huge blast of nitrous and nothing for the last 2/3rds of the run. When we ran my Pro Mod drag bike, we would keep the bottle in a cooler with ice and then take it to the staging lanes wrapped in a cold ice water soaked towel. When the last run of the class before us was doing their burnouts, we would install the bottle. We would leave the line with 900 PSI of bottle pressure and try to cross the finish line with 900PSI of bottle pressure. That way we had a consistent charge of nitrous for the entire quarter mile. Our on board data retrieval computer always the quickest runs when we ran the nitrous like this. 7.16/190.0 will get your attention!

Great job Mikey!

Wish we could have been there!...............

 

[Master of Faster]

Thanks for the explanation Freddie, makes sense

Mikey great job.

Exactly Freddie!! I used to experience this with my Mustang(pre-supercharger) with a 150 hp dry shot of nitrous. A hot bottle would hit soft, prolly due to too much fuel pressure and ofcourse your explaination!! Most of my succesful shots of nitrous came at night after the bottle has cooled down.

I really never thought of this until now that you mention it!! Sounds like a full bottle at 900 psi would work most consistant, as opposed to 1200 psi hot!!

Great job Mike!!! #5 qualifier and #4 finisher in the Power Adder Quick 16!! You'll have to go get em at NYIRP in the end of July!!! Glad I could help out!!

 

[dirkdiggler]

One reason

It was faster for one reason, anything above 80 degrees you acctually start losing HP. the bottle Terry Ran was at 93 degrees.

Here is a chart that shows this power loss.

 

[87gtNOS]

Funny how I have had a digital laser thermometer all this time and have measured bottle temp many times with it and never clued into this!! Bottle temps in my car were always 90F +!!!!
