HAHAHAHAHAHA just got back from my uncles workshop very good stuff.
Redoing my cousins Javelin Rambler (which is now mine to race

) we were running a few tests he was crazy about the noise (he took the exhaust back end off and left only bout half of it under the car).
Now this was a new "improved" javelin is no longer original 5 speed ratchet shifter upgrade, 7.2 litre V8 supercharger so thinking we had everything right on the dyno take it around town aye?
yep just like everything else lacking shifting speed take it thro all the usual tests and this time i remembered to check the timing ends up thats wat was wrong with both my lasers and nothing so thinkin back to how things work i decided well its a long shot but wat about a new shifter or sumthin? yea do that nope dont work, new valves n springs? yea try that
nope....
anyways long story short ive never heard of this but it stopped as soon as we changed it to a heavy duty Limited slip diff HAHAHAHA that made me laugh so hard and now i have titanium valve springs and valves and uprated pistons and arc spark plugs blaster leads and coil and a Nitrous oxide system in a laser HAHAHAHAHAHA just thort id share my fun with you all
