Re: My 88 Olds wagone U/SA 10 Pennies
Tried posting pictures from phone using imgur and couldn't get to work. So he goes
1st pass shifter not adjusted right and couldn't find 2cd. But ran it through at 15.36 at 86.3 with AFR at 11.7. Couldn't get shifter to adjust so i felt for it on second pass. Changed secondary rods from. 048 to .055 with a O hanger. 2cd pass 14.72 at 88.6 with 12.1AFR in high gear. Shifting somewhere around 6800rpm. 1.88 60 ft. Leaving at 2200 rpm Adjusted DA 2300 3rd pass battery was dead in staging lane and I was done as the were around 300 cars and it was midnight and no time to charge. I was able to get car 25 lb. Over minimum. 4330 total weight. Things to do, tighten belt on alternator. Add second battery. Need weight anyway. More tuning and spark plug reading. My goal was 14 flat and I know I can get there. Finish line rpm was 7000. Using Wallace calculator it showed 13% slip so I need to address that. |

It was actually fun driving a loud slow car. The young kids have me silly looks. Some questioned and understood. For a station wagon it got allot of pictures.

Re: My 88 Olds wagone U/SA 10 Pennies
Good start, Jeff
Probably need a better baseline before you change anything major. Max out the timing and carb and the mph will come up some. I'm not surprised the converter would be a bit loose with that much weight. Might have to pull the fin angle back towards neutral (straight up) Better get back on it soon. April's almost here and the first 100 deg. day. |

Re: My 88 Olds wagone U/SA 10 Pennies
Some updates.Found a good transmission pan for $80 from Intergity. Bought a recon battery, cables and master switch for $120 total. Found 150lb. of weight at local auction for $19.00 New total of $8422.00
I will be going out to test Friday night. I think with 3 or 4 passes I can be 14.50. @ 4330lb. Thats 25lb over minimum. I will post Saturday the results. |
Re: My 88 Olds wagone U/SA 10 Pennies
Some more tuning last night and I reached my goal of 14.50. Jetting and shift points are what I worked on. I final have been way to lean and way to rich. Still shifting 1-2 late but 2-3 at 6400 looks pretty good. I have saved the run on the play back tach and will see if I can record on phone and transfer to here and see what you guys think. One thing is the motor does not like synthetic oil. I swapped out the plain old 10/40 for some synthetic 10/30 and it smoked all the way down the track. Not bad but I can see the small cloud in my mirror. Moved weight from behind rearend to just in front in hopes to get car to drive forward more but it didn't show anything in 60ft. Air was at 2700 and ran .2 quicker then 2 weeks ago when air was at 2200. The gains were pretty good, but still need .5 to reach my end goal

Re: My 88 Olds wagone U/SA 10 Pennies
I assume your running radials,how much air are you running?.You should be able to go pretty high on that car and maybe pick up a few ticks. gsa612

Re: My 88 Olds wagone U/SA 10 Pennies
Any updates, Jeff?

Re: My 88 Olds wagone U/SA 10 Pennies
Heat in Az.has stopped me. 14.51 best so far by just jetting richer. Going to tighten converter as it is way loose. Then a couple different collectors to try. I still think 14 flat can be made in decent air.

Re: My 88 Olds wagone U/SA 10 Pennies
Finally went testing before div 7 race next week. With the converter having 11% slip I tried the john deere hydraulic fluid in transmission. Sure enough it worked. I reduced finish line rpm by 300. By having less slip and running my weather station stats from the spring testing I gained .06 in ET. Even though it's not enough lock you in high gear it will get me by for next weekend.

Re: My 88 Olds wagone U/SA 10 Pennies
Little update of work performed. Changed from a 6.14 gear to a 5.57. Hoping to use motor torque to accelerate car. Front end alignment. Front end had severe toe in. Took front GM brake calipers off and freed up movement in hopes to keep pads away from rotor. They had allot of drag before, now they barely touch rotor when spun. Moved some weight to the back as I moved some to the middle of car and 60ft slowed. Installed cool fuel can. Installed fuel pressure gauge and found out I had been running 7lb of fuel and was wondering why car had a blubber to it. Had a cheap gauge mounted right at regulator and was reading wrong. Racing team race this Sunday and see if anything helped.
