So i have been doing some research about adjustable cam gears at a few different MPG websites and it seems to me that if i were to get an adjustable cam gear for 95 SL1 SOHC i would be able to advance the cam timing a few degrees and shift the powerband down the rpm range hopefully to something like peak torque at 1400-700rpm. I know that it would reduce the top end of the car (the SOHC only revs to 5500rpm anyway but i stay below 2500rpm - 2600rpm max) The peak torque on the Saturn SOHC engine comes on right around 2450rpm. I know that is low but since i shift between 1600-2000rpm i figured it would drastically help to be able to have peak torque available at those rpm for acceleration and cruising (60mph at about 2100rpm) i know that diamondlarry had a small cam advance (2-4 degrees) when he had his head shaved and it supposedly helped out alot. The adjustable cam gear for the Saturn also is only about $75 so i think that is a reasonable enough price to have torque available at such a low rpm. Anyways let me know what you guys think.
