More 1/8 mile Torbo results...Looking Good!

[PT-Dave]

Just got back from the 1/8 mile drag strip with my factory stock Turbo. The only things done to it so far is the K&N drop-in filter and Mobil 1 synthetic oil.

Tonight the results were very satisfying as well as astonishing. I discovered just how much the turbo likes cool engines and cool air. The temp was in the low 80's but the air felt cool after the sun went down.

The nitty gritty:

Run........60ft..........E.T.........MPH
1..........2.228.........9.846.......69.961
2..........2.190.........9.775.......70.484
3..........2.164.........9.525.......72.005 (after a 78 min. cool down)
4..........2.205.........9.860.......69.999
5..........2.240.........9.915.......69.748
6..........2.201.........9.803.......70.415

Run #3 really amazed me. I dialed in a 9.670 to give myself a margin of error, never thinking that I would trim almost a 1/4 second off the second run. Needless to say, I lost the race since I broke out by .145! A happy feeling due to the time and speed but GRRRRR! I hate to lose! The last three runs were done during time trial segments, and I wasn't able to get it cooled down like before.

All in all, a great outing! I wonder where I can get it to with intake and exhaust improvements?

Looks good Dave , hoping to get mine to 1/8 mile strip next month ! Then post my runs ! Want get this rear shock straightened out first,lol ! Thanks for posting !

Good information... nothing like taking runs at the old dragstrip...

Great numbers. Looking at yout 60' times, are you still running the stock rubber?

WOW looks good Dave ,,I have but one question why only an 1/8 mile instead of 1/4 mile whats the reason for 1/8 mile times verses 1/4
I just found out today that there are friday night drags here in AZ and will be going to one real soon and they only do 1/4 mile times just want to know why thanks..

[PT-Dave]

Brad: Yes, I'm still running stock tires. This track uses VHT for traction and I must say, it works very well! In my six passes, only one car, in the last run, beat my 60ft time, but then he ran a 7.90 for the 1/8, so he had better be faster than me, right?

Ramcrzr: I haven't been to a 1/4 mile track yet, that's why I only have 1/8 times. I will be in San Antonio next month at a 1/4 mile strip, and I'll post the times I get there, too.

Dave , congratulations on your runs .
They really do look good .
I used to live just south of you I guess , in Keller ( between Watauga and Roanoke )
There used to be a 1/4 mile track just south east of there .
Is it still there?

60' times can be deceiving. If you do what is called "shallow staging" you will get a better 60' time because you'll get a run at the clocks before your front tire leaves the starting line beams. If you "deep stage", your time starts almost the instant your car leaves the line, giving you less momentum into the timed portion of your run. The distance between the initial activation of the stage light by your front tire to the point where the front tire has passed the beam depends on tire diameter, but your car could conceivably roll 10+/- inches and still be within the stage beams.

Next time you run your car, try rolling very slowly into the stage (second) light and stop, barely activate it and then make a normal run. For the next run, roll forward until the top light (prestage) goes off but not too far where the stage light goes out or you'll get a red light., and then make a run. You will notice the first run has a better 60' and 1/8 mile time than the second run.

AA/PT : Hey, don't give away my secret! I have used shallow staging for years just for the reasons that you stated. The hard part is gauging the "jump" you get by doing it that way. The reaction times can look pretty slow, but you are really moving when you trip the start beam, so the reaction time is not as relevant. I had a couple of red lights, since the Turbo was much quicker to go than my old stock cruiser. I had to adjust my reaction to avoid the red light.

Another advantage of shallow staging, assuming your opponent stages normally, is that your opponent can actually be tricked into red-lighting himself! That's really fun to do!

Amen, Brother Big K! Glad to see some turbo "rubber" meeting the "road" for once.
