Drag Racing Discussions > Front Engine Dragsters
What did you do on your Front Engine Dragster TODAY?
gregm784:
Some of my post run procedures are:
Put car up on stands
PUll valve covers, run valves. With shaft rockers they NEVER move, but you will find a loose or tight valve is something is going amiss.
fuel the car.
Pack chutes
Check over everything (trans, motor, oil system) for leaks
reset seat belts
Torque rear tires every couple passes
Check front tire pressures every day
Put extra 1/2 pound in rear tires for adjustment in the lanes for track conditions.
Drain puke tank each night of racing.
Probably some other stuff that i can't think of. :)

Best part of running valves every run at a bracket deal is it screws people up to see someone work on a car. 90% of the bracket racers think they are driving street car ansd should never have to work on them.
I pulled head off brothers car one night because we had a little leakage in one valve.I was just touching it up. You would have thought we had a exploded nitro engine sitting there. Cpl guys almost wrecked golf cart sliding to stop to look because we pulled a cylinder head. Coming for top running TA/FC and TA/D background I thought it was just a very easy evening at the track.
You would be amazed at the number of guys that go full season w/o pulling VC's and are proud they are that lazy. Then they are amazed that something broke.

Glen,
Have you checked cranking compression on both sides..Asking because we had a 45* cam in a raised cam block once and should have been 48* cam.It caused the right side cranking compression to be way off from left side. Probably not same but something to check if have not,cam manufactures do screwup.
Now with the 14-71 hi helix we had more fuel on right side due to discharge air pattern of blower.This was with the delta hole. A full open bottom may have total different pattern. Just a cpl of thoughts on why temps might differ side to side.

Compression is within 5 % on all cylinders.
I am pulling the blower right now to repair the leak on the right side and will look to see if I see any pattern in the top end lube in the intake.
My thoughts is it is a problem with the transmitter transformer for the egt's on the even side, I will be switching the two boxees left to right to see what happens.

yup, coming from A/Fuel, running valves is just time for me to talk to the car.
I found out how little timing is too little on my small block one day and got both head gaskets (center ports on a SBC get real hot when retarded). We yanked heads and swapped gaskets between rounds. We had quite the audience, so i know of what you speak. (48 minutes if you're wondering).
