I just bought a YSI for my 3400# 91 Z28 and was looking for some input.It`s going on a 406 sbc,production block,9.55:1 comp.,stock Track-1s,hyd. roller .510/.525 232/242@.050 . I`m using a TPIS Mini-ram with 36# injectors in the fuel rails that came with it. I have a Weldon 2015 pump/regulator,-10 into the pump,-8 to the pass. side rail,thru the TPIS balance tube to the driver side rail,-6 to the regulator and back to the tank.
The car goes low 11s @ 117-119mph N/A, low 10s@ 130-132 on a 175 shot. For now I`m looking to duplicate the performance on nitrous with the s/c and go mid 9s later after I replace the block with a Little M.
What size injectors and what modifications to the fuel system will I need? (FAST ecu)
What blower pulley sizes are needed for both setups? I have an 8" 10-rib crank pulley and shift at 6200.
I`ll also be using a Griffin 3 core a/a intercooler measuring 30"long 6" tall and 3.5" thick.
Thanks!
Glen
