In March I installed a PTE 6776 BB 'S' cover. Also replaced the stock IC with their SLIC.
Right now I'm running a TT chip / 93 octane. Base timing and I have about 10% fuel removed in all gears. It's still running rich - high 700s / low 800s on the O2s. No knock issues to speak of.
I've got the turbo set at 18 lbs.
I've made some baseline passes before adding Alky and upping boost and playing with timing (and fuel to lean it out a bit more).
Best pass so far is an 11.91 @ 109 with a 1.67 60'.
My first question is, does that ET look about right based on my setup and boost level? Second question is, once alky is added and timing and fuel are tweaked, would 24 - 25 lbs of boost get me in the high 10s?
Here are all of the supporting mods:
Engine/Exhaust:
-rebuilt about 5k miles ago
-204/214 flat tappet cam
-ported stock heads - Brosnonian stage 3
-steel center main caps
-double roller timing set
-60# mototron injectors
-TurboTweak chip
-160* t-stat with billet neck
-Caspers cam sensor cap
-3" ATR downpipe
-Turbonetics Evolution wastegate with in-car adjustability
-test pipe with cutout
-Hooker 2.5" catback
.020 forged JE pistons
-hot wired Walbro 340
-3" LT1 MAF w/translator
-Precision 6776 BB 'S' cover
-Precision SLIC
Sorry if I missed any key info. Appreciate any feedback.
