More Timing and Less Boost or More Boost and Lower Timing? Boost adds more than timing. 1 psi of boost can add 20 hp, 30 hp or even 40 hp (depends on na power), but 1 degree of timing won’t be anywhere near that!

LS3 Intake on Cath Port Heads With Adapters! The LS3 intake is arguably the best factory GM intake ever made, but does it work with cath-rec port adapters used for LSA blower installs? Anyone else ever tried or tested this? The answer is it will bolt on, but the LS3 intake with adapters makes less power (by 18 hp) than just running a TBSS or Dorman LS2. I wanted this to work so bad back in 2018 when I tested it, but it just didn’t pan out. Get a cath port intake! Make sure to check out the sales

Intake Tech Tip-Single or Dual Plane or something in between? A dual plane with an open spacer usually shifts power slightly higher in the rev range, without costing as much torque down low as the single plane. Of course it doesn’t usually make as much peak power as the single plane either. It’s kinda in between!
