This might be a question you have already answered, so I'm sorry if it is, but how long has it taken you to build it to get it to the stage that it is at now?
 
engine is in place I've passed the tune pipe through the spoiler stand it looks better that way .i think

i need a diffrent petrol tank cause as you can see the engine starts when the engines reservour emptys it revs up and stops . any suggestions please thankyou . can i put a vent hole at the top of the petrol tank ? thanks

i think it reving up when the tank empties is the same as when a nitro tank empties and it runs lean for a second as the last lil bit of gas runs through...not real sure on how to stop it from doing that

Nice looking dragster.I bet your friend is kicking himself right about now that he didnt build his...Just below the carb and reedblock if engine is reed ported you can put a puffer system to pressurize the tank similar to the Nitro set-ups with plastic tubing and quick release connectors from pneumatic air valve set-ups by drilling a port into the crankcase and drilling/tapping the tank.......It can be done without disassembling the engine by stuffing rags in the crank and a vacuum to suction out the chips and will keep the engine running tops at all times until the tank empties....Its safer to disassemble the engine...You can gain some nice hp's and revs with crank stuffing,boost port addition and retiming,compression boosting by removing bottom basegasket,the addition of triple stage reeds,rocketkey,boost bottles w/nitrous booster and watercooled carb to go along with that pipe...It can also be boosted up to 15-17:1 comp and run on methanol.Plus check out the MSD Kicker ignition systems;-theyre killer for sparking-up the power...Keep up the great work..

i know you know what you're talking about but i dont know much about engines . i was thinking of putting a nipple in the exhaust pipe and feed it to the tank ? thanks for your help
 
I'm on a break from the dragster because I'm trying to get my turbine car and 3 other cars ready to go racing in the uk in september thought id update you all ;)
