I once had a camero that ripped the drain plug when it landed from a wheel stand and ran through at 8500 with out to much damage to the crank and rods, maybe you will get lucky. Anyway looks like a good beginning to your project. I was wondering what the rules say about aero modifications to the car, can you remove the headlight bezels and block the grill opening? You should write more about the car, where it came from and the engine development you guys did. Congrats on getting it to the track and going as fast as it did, even with problems.

Well its been a while since I have updated my build as usual life can sometimes get in the way of racing. Well other than overcoming the build cost and the expense of getting married in May I finally have been able to scratch alittle money together for another attempt at a Maxton record. There being only two races left before the ECTA loses there lease its time to get serious. I sure would like to have my name on one of those records when they close the books on Maxton.

 I left off with a hurt motor and about 17 mph short of the record. I went through the motor and luckily nothing major apparently the short time with out oil pressure didn't hurt anything (had it apart so new bearing, seals ,etc. after some talking and problem solving about my head gasket issues I have come to the conclusion it was pure stupidity on my part. On all the racing engines I have built in the past I always lock out the distrubitor or use a crank trigger and adjust timing digitally. Well not on this engine set it to about 36* timing for the first couple of passes to be safe. Well Duh this engine still has mechanical advance once it going the timing was way up there so detonation and bye bye head gaskets.

 The major overhaul was converting to a manual trans. I decided to go with a toploader and a quicktime bellhousing for safety reason. Wow what a mistake. ( I covered the issues on another tread on this forum so I will spare everyone the details) I lost about 4 months dealing with that but it is back together the motor is in and a handful of little things and were going back to Maxton for another try. I was thinking about a few hours on a chassis Dyno any thoughts. I have never used one but considering the drive train change seems like a good Idea. Does anyone have any thoughts on the percentages of HP lost from flywheel numbers to rear wheel numbers? Any way heres a few Pic one of the motor installed and a couple interior showing the shifter and the fact the car now has the right number of pedals a race car should have. Thanks Sam

Im shooting for the sept. race and if all goes well and I have any running parts I will try again in Oct. The later date is probably the best for a record attempt with the cooler (hopefully) air. You wont regret making it out it really is a cool event. Looking forward to meeting you there. Sam

Just thought I would share with you all our darn near record run at maxton today we got started late due to rain the first passes did happen till about noon we made two passes 145.17 and 144.90x something all on a 147.xx record so close but yet so far that was the 3rd and 4th ever pass on the car and the first 2 with the 4 speed. We are going to try it again in the morning with hopefully better air. The temps were mid 80s with almost 100% humidity most of the day. the last run we had about 6-8 mph head wind so maybe we have a chance tommorow here is a link to our first pass it from the starting line so not much on the hi speed side.

Good luck guys!!  I know those last couple mph are hard to get but well worth the effort when you get them.  Keep on trying. Wink

What modifications, if any, can you make to reduce drag? Often a lot of improvement can be found there. Did you do any carb tuning for jets etc.. Like you said so close, only 3 mile an hour and you will own the record. Whats are your class rules as far as ducting etc.? Chuck in NH

Just like with Tim's truck we are running a production class so no body mods no air dams or splitters allowed. We have a nice front rake in the ride height but thats about it as far as aero tricks that are legal no taping no ducting allowed. I will seal my carb to the scope for fresh air but just haven't had time if all goes we today i can spend some time this month trying to go faster and not just rebuilding the car. The tuning is untouched i think there is something left with timing and jetting and the air was about as bad as it gets yesterday. Im going to put a little more timing in this morning and and rase my shift points a couple hundred RPM and hope for some cooler dryer air and a lot of luck. Thanks Sam

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.
