I have been tuning a lot since getting the car. The car has been seeing 26-27 psi and holds it fine. I've played a little with fp and timing and as expected got some knock here and there as I decreased fuel and/or added timing.
So I was reading a thread where Grumpy was talking about using an air regulator as a boost controller. I had one laying around and hooked it up. This was about 7-8pm, probably 80 degrees out, remember I have a pt54, tial wastegate, huge FMIC and huge 3.5"dp and straight shot exhaust. Stock heads and cam though. My Meth knob was at 6, 43ish psi at FPR line off, tt alky chip, basically what you see in my sig. First hit wot it pegs the boost gauge the needle literally back between the oo's in boost lol. I of course immediately get out of it (afrs looked good 10.9-11.2, no knock). I crank the reg down and hit it again, same thing, has to be 35psi+, sounds great, goes like hell, I get out of it. So I pull over (this is in an old peach orchard) and check the scanmaster, 791 0 knock, my innovative gauge read 10.8 (it normally reads 10.2-4.)
The reason I posted this in this section is because how impressed I am with the alky kit. I cannot imagine that much boost with no knock any other way on a stock motor.
I of course pulled the reg off and I am back on the waste gate spring (18.5lb spring) I see 26-27psi set up this way. Even with good afr's and no knock that much boost worries me on a stock block.
