is that an ATS TB inlet? looks nice. i ordered one last week!

Yup, I ordered that and the GM Knock Sensor Conversion for Doc to install. Along with the healthy dose of goodies that he's putting in the car.......should be really niiiiiiice.

i woudlnt recomend using the GM knock sensor. it dosnt work correctly for our cars and ats should stop selling it imho. keep the stock sensor.

Good words man. I'll clear up that I wasn't offended by the statements, just getting sick of them.

As for piston position in the cylinder, taking an LT1 as example, that's a stock 3.48" stroke. That's 3.48" where the piston could be located anywhere in that cylinder. If you're talking about a 4.00 bore, then you're looking at a volume change of approximately 43.75 cubic inches or .7125L on that cylinder between TDC and BDC. If there is a condition that's severe enough, you could possibly even detonate prior to the intake valve closing before the compression stroke has even begun (ever see a V8 with a couple of swapped plug wires). Given that, I feel that there's going to be a marked frequency change in the knock between the two points (TDC and BDC) with the volume change. I know it's not a 3S-GTE but the same theories still apply as a motor is a motor for the most part.

?
not quite sure what you're going for here, but i think you were just agreeing which is kewl.


also, J&S sells some kit which uses a wideband sensor and is very accurate, like $400?
it seems like it's just a piggyback sensor(semi-standalone? lol)

also, bringing a V8 in was prob a bad idea, since sensors are kept within families. although each engine is slightly different, going from a I4 to I6 would be bad. I don't think you were trying to compare the 8 to the 4 though...i just can't deal with reading all this stuff more than twice.
