Work, work, and more work has kept me away from all forums for a very long time. Since I have the day (sorta) off and no chance of taking the gtp out for any fun drives (glare ice everywhere) I thought I would ask a question I've been meaning to ask for a long time.
Where do I stand with my current setup:
Headers
1.9 ratio modified rockers with 90# springs are GM LS6 (yellow springs)
SS intercooler with flojet pump
Ported supercharger - custom, no idea on quality here.
3.5/3.1/2.85" mps
Headers (test set from that one guy in MN. that I think stopped making them)
Cat and U bend removed
Custom CAI with cone filter
42.5# Lucas Injectors -Flow matched
Good old DHP PowerTuner - Tuned by me -
1 heat range colder plugs
PRJ Ignition Wires and the alternator re-wire
I have been tuning based on the maf trying to get everything close to 0 (-3 to 2) and then messing with A/F ratio and timing at WOT (keeping KR below 1 at all times and never if at all possible). I noticed a huge seat of the pants upgrade when the 1.9s went in. Now I'm not sure what else to tune and where the optimal shift point would be for my current setup (I'm at about 6100 right now)
I also have access to one of the best mechanics ever who I think is on this forum, but might not be anymore (he ran a turbo setup for awhile that was amazing).
Questions:
- How does my setup look?
- Anything I missed as far as smaller/complimenting mods?
- Any guesses as to what kind of power/quarter mile times I might be looking at?
- How should I go about tuning at this point for both cruising efficiency and WOT power.
- Any other comments/thoughts/questions?
