HSW... help on jetting (a question..) Ok.. i have a HSW wet kit...
it says at 50psi fuel pressure...
100hp = .052 N20 jet and .028 Fuel jet
125hp = .057 N20 Jet and .031 Fuel jet
I was curious.. since the LT1 actully runs at like 45 psi.. would it be safer to run the .052 N20 jet and the .031 fuel jet? Or would that be way too rich? I dont have the .028 jet but i do have a .029. Should i just use the .029 jet??
Thanks.

If you have a wideband O2 sensor in the vehicle you can swap jetting around if need be (or your on a dyno). If you don't have a way to measure A/F I wouldn't mess around with the jetting, but you should be okay with a .029 jet instead of the .028.
