me thinks you are still asleep lolool.. the head, as in the first pic, has crators in the squish face.. it is a 172 head.. the squish face is the area that comes closest to the pistons, the idea is that a greater pressure area (and the squish is all around the edges head chamber ) is...

ok dokey here is an estimate of the amount of weight you would have to remove to equal a coresponding increase in bhp for the times given above. assume a start time of 15.0 and weight of 2500 all up. 2500 lbs @150 bhp ET=14.9 2500 lbs @160 bhp ET=14.56 or loose 158 lbs 2500 lbs...

detonation has to occur before the sensor can take any action, the role of the sensor in WOT (wide open throttle) operation is uncertain on the Sirius ecu as fitted to the 172... the fueling on WOT is a simple table with no lama correction. the dame here is pre-ignition or hot spotting. a...

Hi Craggs I will give you one tip... how to make a small amount of money out of strip time racing ..................... ................... Start off with A LOT.. the first few seconds is relatively easy...

oh m8.. just in case it isnt obvious from the pic.. the squish area are absolutely level with, and form part of, the head face. Joe

Hi, Nick m8. there were virtualy standard 172s pulling high 14,s / low 15s. your car is also lighter. with 250 you could certainly run in the high 12s low 13s. Its simply a matter of comparative results. If you know what the best run is std, you can calculate the apx power needed...

hi Ben m8.. Porkers system is a cross bvetween phase shifted vvt as seen on the 172, and vtec as seen on the honda. It is 2 stage phase adjustable - not constantly variable - It also has a 3 lobe cam with a large upturned bucket follower. the follower normally rides on the outer 2...
