This is my first official loss against anyone driving my car. I say "official" because I think Tim Aro beat me on a run at the extreme school but the data was corrupted and he thinks I beat him. When we ran with timing equipment, I eeked out a .003 second win.

In this case Heikotter beat me by ~0.2 seconds.

 

No shame there...

 

Quick synopsis: You were more aggressive on the start, but he ate your *** up in the slalom.

 

He really launched aggressively on both of his runs, (wheel hop and all) and we both thought he was putting a little time on me there, however my single chirp launch seemed to work just as well if not a hair better.

I was a little ahead (by a very slim margin) until the first left after the turn around. The camera never changed position between runs so you can use the cones' relationship to the wipers for relative location and angle. (Full screen and HD to see the details) I was actually a little late on the throttle there. (Not a common mistake for me)

He thought I was setting up better on side B and, looking at the video, I did have slightly better angles, but I was also adding distance to get those angles. Since I didn't really change the gap after my mistake, I think I merely "broke even" with my setup+speed vs his shorter distance.


*edit* I may have closed less than a tenth of the gap I created with my mistake....

 

Nice driving both of you. How do you like the Quaife? Do it again would you go clutch type?

 

I love the Quaife, but I don't think I have enough experience with clutch-type diffs to give an informed opinion between the two.

I have heard that there is a new quaife-type diff that you can pre-load so that it still works with a wheel in the air.

I would be all over that one if I were in the market and it really works just like my quife + works with a wheel in the air.

 

Nice job & interesting side by side.

The quaife was imho the best mod I did on my Z.

 

BSP setup?

 

Closer to STR (except the not legal Front arms and clutch)....

 

I'm surprised they didn't allow the lightweight flywheel in STR. It seems to fit with the other allowed mods in the class.

At least the flywheel is good for a little time. The metal bushings in the A-arms, however, do not make my Z any faster. (Great A-arms though)

We were both on the same crappy street tires. (360 TW Sumitomo's)

They didn't have any sticky 275/40-17's (Other than toyo's that hate heat) when I needed tires so I went with the cheapest I could get.

I'm hoping the new street tire stock class rules result in more sizes from the sticky tires.

 

Ty for the input. I havent heard of the new quaife, Ill look into it.

 

It's supposed to be a new Quaife-type (helical) but I don't think it's actually a Quaife.

I didn't look into it when I heard about it because lifting a rear wheel is not really an issue for me.

A quick search brings up a mountain of Quaife stuff so I will have to inquire at the track for more details.

This may be it:

And from wikipedia:

http://en.wikipedia.org/wiki/Torsen
"When a Torsen differential is employed, the slower-moving wheel always receives more torque than the faster-moving wheel. The Torsen T-2R RaceMaster is the only Torsen to have a preload clutch. So, even if a wheel is airborne, torque is applied to the other side. If one wheel were raised in the air, the regular Torsen units would act like an open differential, and no torque would be transferred to the other wheel."
