[QUOTE="97desertCobra, post: 9401953, member: 53488"] Yes the gears will help but for every 1 point in compression increase you will gain about 5% increase in power and torque. I can't remember the exact compression for stock 99-01 Cobra's but for 96-98 its 9.85.1. If I were to drop down to 8.8.1 and keep everything the same its very likely that I would lose about 5% of my horse power and torque. That may not sound like such a big deal being just 5% but our DOHC engines already suffer from lack of low rpm power and torque. So just an example, if you make 300rwhp as you are now and then drop to 8.8.1 compression and leave everything the same, then you would probably make 285rwhp. I would stay as close to stock compression if I were you, that way the car does not feel sluggish. Centi blowers also take well to increased compression more so than PD blowers due to the fact that centri blowers generate less heat. [/QUOTE]
