Racing Results - 2G GSX auto

1/4 mile racing times for my 1998 GSX

16.829 seconds @ 83mph

60' in 2.592 seconds

Stock T25 turbo, stock airbox, stock airfilter, stock exhaust, stock intercooler, 1G BOV, hard upper-intercooler piping. The Boost Control Solenoid restrictor removed. It is reading 10psi with a quick spike to 11psi. Definitely has boost leaks too.

15.801 seconds @ 86.34mph

60' in 2.382 seconds

Stock T25 turbo and stock exhaust, stock intercooler, cheap cone airfilter, Translab shiftkit, NGK BPR7ES plugs gapped to .028", 1G BOV, hard upper-intercooler piping. Dejon Tools MBC set @ 15psi but it is not holding it. Later found that all of the fuel injector seals were leaking boost. Turbo was trying to push 18psi and only 11 was getting to the intake manifold.

15.279 seconds @ 90.86mph

60' in 2.288 seconds

Stock T25 turbo, stock intercooler, cheap cone airfilter, Translab shiftkit, NGK BPR6ES plugs gapped to .028", 1G BOV, hard upper-intercooler piping, hard lower-intercooler piping. Dejon Tools MBC set @ 12psi (occationally spiking to 16psi), only running a 3" downpipe for the exhaust.

Compression test shows 154, 148, 136, 132# and boost is leaking into the block. Definitely in need of some maintenance or a full rebuild. Good enough 1/4 time for now.
