Are yall using stock injectors?
The stock injectors will furnish enough fuel for a low boost ZR-1
We are increasing the injector size on the LT1. Will let you know what that is when the dyno work is done and injector size is proven correct.

What size turbos and piping are yhall going with?
LT5: you will have the option of ordering several different types & sizes of turbos. from bushings to bearings. Base setup will include 2 Garrett 30's.

LT1: same as above only a single Garrett 60.

Both will have a single 3" dia exhaust from the engine to the turbo(s) and a 2.5" return for boost air. Both designs will have 3" turbo outlet exhaust to dual tips.

Any power numbers yet
If you will re-read the post I wrote above, you will note that the fabrication is nearing completion, so we have not yet had a completed system available for dyno tuning & testing. However, we're expecting about 390 RWHP on the LT1 @ 8 psi and LT5 @ 425 RWHP @ 5 psi, both with no internal engine mods.

Potential is from there up is enormous if an individual is willing to prep the engine for higher boost.

When we're done with development, we'll furnish a full report on the before and after turbo dyno results, with complete system specs.
