Thanks M & M!

The pics show some of how the car reacts. We normally race with 5 1/4"s front-end travel, with this set-up we had 2.5"s of front travel. The rear if I remember right, we have about 5"s total travel/separation. We have to guesstimate on the rear separation, don't have shock travel sensors & don't want them. Anyway, that's the tightest we have run the separation for this race. We usually have about 1" more separation.

Also, our baseline weight bias on the car is 50/50 at 3100 lbs. race ready. We can also put the weight bias at 49/51 with 50 lbs. of ballast under the rear bumper.

I did a quick look over of the data logs & everything looked pretty good. Except I found some minor RPM spikes slightly after the converter flash. Pretty sure I was on the edge of spinning the tire in that area.

Here's the 1st round time slip to go with the pics above. It was my quickest reaction time of all runs at this race on a .400 pro tree. I was trying some things differently & to get more of a wheelie; it slowed the cars reactions. While not great, the car driving out of the beams with little to no wheelie; I can get better .020-.030 lights, but still not where I want it.

Thanks Tex!

Good luck on your racing this weekend & thanks for the links.

I ran a 5.80 race a few weeks ago along with out regular points race. Man it was cut throat. The guy that won it was no worse than .019 on the tree in eliminations. I had never run 5.80 index before we usually have 6.0 index races so I was searching a little for the index ET through the day adjusting my shift point on time. I shift on rpm when off the foot. Weather was rough too, mid 90s with 60% humidity, 140+ water grains and 4200+ DA.

I was 5.768 and 5.777 in time trials. Pedaled to a 5.824 first round then a 5.78 double break out. Got behind on the tree in the third round .024 to .047 and was 5.786 needing to back into him but did a bad driving job. Only had .003 room to turn on the light in that one anyway. I really enjoy index racing and wish they had more of them at my track. This day was a Wally race for all classes, plus a cool ring.

It's funny but my car is quicker to 60' off the foot leaving at 2600 than off the button leaving at 4000. I was 1.231-1.235 off the foot and 1.237-1.244 of the button.

I really like these index races I've been running. It's nice not using electronics as a crutch & let it be a driver's race. Was the index you ran in no electronics? Sure would be nice if NHRA had one class like that; like maybe Super Street, but that's not going to happen!

This past race my time hits were 5.778, I'm usually a little slow on the 1st hit; 2nd was 5.764. In eliminations I used my right foot throttle stop (ripping) to slow the ETs between 5.815 - 5.886.

If you mean not throttle stops then yes.

Ours are no electronic throttle stops, no delay boxes & depending on the promoter .400 or .500 pro tree.

2BKING

.400 tree and nobody worries about delay boxes since it’s that tree. Very few 5.80 cars are carrying anything in the box. I have mine in just to run my transbrake. It’s zeroed out though.

My shift controller can shift on time or rpm so I shift on time for index and rpm for Footbrake. It starts the timer from a preset rpm. I kept pulling time out of the shift to slow down.

A good day racing Saturday .
Started off damp and lost Q1 but still had 2 and 3
For track championship rounds we qualify off reaction times . I was #3 of 27 with a 0.011 . Then reverts to ET after E1 .
Class is 10.00 - 12.99 no box .
DA was great / fast all day . Was 1139 @ Q2 down to 0 in E2 to settle mid 300s for rest of eliminations .
E1 I had lane choice but was chased by a 10 teen car . Had the tree and backed up giving him the stripe . Double breakout for the W .
Air was just fast .
E2 Lane choice and chasing . Good tree advantage ,drove around a mid 10 car for the W
E3 Lane choice and chasing . Opponent had issues in burn out and on track . Easy W .
Semi Had #1 qualifier . He is a mate and was chopping the tree hard . BUt those late model efi LS are not super consistent . His 0.005 to my 0.021 was not enough as he broke out taking the stripe .
Final Chasing and somehow Martin had lane choice and I was in left . No matter .
My 0.005 to his 0.027 was enough . Drove around and backed up for the W . He did say his car didnt hit the number .
The Goodyears were great 1.46-1.481 spread .
Lights were great 0.005 - 0.047
All in all a good result .
Except for lack of prize $ . Less than the entry .

Tex,

I watched all your runs; it was nice to be able to watch the elimination rounds. I watched them last night. I was busy this past weekend with the grandson & limit my time on social media.

Anyway, congratulations on your win! That sucks about your winnings.

2BKING

Good work Tex. Sounds like a great weekend.

thanks guys .
Definitely felt like I was on the tree more consistent .
