It was good to get back out on the track.

We had last months race canceled for rain which was good for me since I was still waiting for my replacement oil pan to arrive and once it did, I still had to modify the crap out of it to fit....

I also fabricated up some limiters for the front suspension to keep it on the ground and as you can see in the video it worked perfectly.

First qualifier and second qualifier I was very timid about getting after the car and smashing the oil pan again.

I had a single in the 1st round eliminations, due to my opponent locking up his engine in qualifying. So with nothing to loose I went a little harder. Put the exact tune up in it that stood it on the bumper last race.... 25% to 50% in .6 sec. 50% to 100% in by 1.1 sec. Car went a 1.29 60ft and 5.69@120MPH.

In second round eliminations I was throwing 30% to it at the hit and the car was just stuck to the ground. 30% to 50% in .6 sec and 50% to 100% by .85 sec..... Just Took me a few passes to get brave enough to go that hard at it but the car responded with a 1.25 60ft and a 5.61@121MPH. I cut a .032 light to his .059.... still can't believe I lost that race.

Anyway turns out someone is posting video of some of our races on youtube and here's everything from Q1 to the final.

As always thanks Gurus.

My old "home" track aside from the ET light boards and retaining walls, the track hasn't changed much since the 1970's.

Good runs, good that the car stayed flat.

It's amazing what a 6" length of chain attached to the lower A Arm to limit front extension to about 1" will do. I mean you can see the front of the car is just about glued to the ground as hard as the rear.

All I have to do now is straighten out the engine tune up where the car will really run on the big end. As you can see in the video the car is still a good deal faster than some and way slower than others... I want to get in the 5.40's on this little tune up so bad but I just don't know that it has the HP to do so. I'm thinking one more race before I say screw it and put the 36 jets (that's my BIG tune up) in the nitrous kit.

For the next race:

After conferring with my chassis builder we are going to shorten up the Progressive Nitrous Controllers ramp a bunch next time out. He thinks I should be all in somewhere around .6 sec total and starting at 30%... of course he don't have to pay for the oil pans.....

Going to take some more jet out of the carburetor as the engines AFR is still very rich when the nitrous is activated and this weekend it responded positively to reducing fuel pressure on the nitrous kit... We went from 6psi to 5psi to 4psi.... I'm just at the lower recommended limit of 4psi and there is no more room to go lower on the NO2 kit so I'm left with no choice but to take fuel out of the carb.

I guess we'll see how that works out.
