I am thinking the gear is too high for the horsepower you are pulling. Could be wrong and the wind could be the culprit. Wish I could do it myself. A run at Boniville with my T-Bird has always been on my bucket list. Will problably have to settle for the drag strip though.

If you factor in the head wind, it looks like you did improve. You just need more favorable track conditions.

mabey switch the gear back and go to a taller tire. a little more carb might help on top end.

Hope you Guys are not too disappointed, you are all over the record with 56 year old technology that you have improved on. You will get there, i know its hard to figure thing out when you only get a few runs each trip. Car looks and sounds great.

Well the final Maxton came and went the records books are sealed and we don't have a record there. We did how ever meet some really good people and had alot of fun. Sat. turned out to be a wasted day we had a sustained 15-18 mph head wind with gust to 25. we made a pass and went 138.9xx way off and didn't know if it was all head wind or some of the changed we made. (went from a 3:15 rear gear to a 2:95 and made a cold air ducted intake system). The car was all over from the wind push so we called it a day.(they also had record turn out for the last race over 3 hr wait to make a pass.Got to the track early Sun morning and beautiful fall morning low 50 and no wind waited in line till 11:45 and made the first pass went 140.1xx it layed down in high gear it just couldn't pull more than 5400 RPM so right back in line with no time to change out the gear. So we decided to pull of the cold air system to see if it helped or hurt. The ECTA crew said runs were going to be cut off at 2:00 not a minute more. We barely made it to line my final Maxton time slip reads 2:01. the car went 140.3xx so looks like the cold air system didn't hurt or help (I suspect in 80-90 degree weather it might show some more improvement). Bottom line we went the wrong direction but we had alot of fun doing it. I think my crew said it best just because we don't have to run the little R sticker anymore does not mean were  not still rookies. Here a video from the last pass at Maxton. Thanks Sam

First let me congratulate you on a significant achievement already with your combination. 145 is flying in a 50's Ford.



As far as Chassis dyno tuning here are some tips.



Ignore the horsepower numbers you get. I have found it is very difficult to relate them to engine dyno numbers. Chassis dynos are all over the place as far as what readings you might get. Use them as a tuning tool , forget about what number it makes and concentrate on making changes that improve the number.



Find an operator that can tune a carburetor. A lot of techs are so deep into efi that tuning a carb is not their strong suit. Keep notes on the air temp and humidity at your test session so you can fine tune at the track based on the dyno data



Use the power curve generated by the dyno to find best gear/rpm combo



I know there is a record in that car!

Yes the chassis dyno is in the works I was trying to run it some before this race but as usual time gets away from you. We have engine dyno pulls but there several years old and the motor has been changed some what. I think it might respond to some more gear also so a new 3rd member is in the works also. I would like to play with engine timing and carb jets on the dyno also. If anyone has ever chassis dynoed I'm looking for any tips you would like to share.

Well you got a good base line to go forward on, great outing, How about a chassis dyno to fine that sweet spot in power? 145 in a 55 ford must have been a lot of fun.

Well we came up short best and only run today was another 145.00 im not sure if we are hitting a aero wall or running out of HP or gearing issue but the good news is it all still in one piece thereare a few thing that we can improve on there still one race left at Maxton and the air should be much better in October. Thebest part is I had a blast and got some of the best complements a Y-block racer can get getting told your full of it and there no way it still has a Y-block in it. Thankfor all the kind comments. (P.S. the scrub chevelle running in my class ran a best of 138.xx)

Yesterday's runs were really impressive.  I have a feeling you will own that record soon if not today.  Sealing the carb to the scoop is a must.  It gave me 6 mph with that single change.  Good luck.
