Thread: Just got a GTP, have a few questions for the experts

but remember reaction time will not effect your 1/4 mile time. the timer does not start till you take off.

Well, I know for sure I wont be satisfied with 14's I want this thing in the 13's prefferbly mid to low, so I guess it looks like my plan to just do the 3.4 with supporting mods isnt quite gonna cut it.....

Looks like I may have the blower ported, maybe do rockers and a tb....maybe that will get me where I wanna be?? Lots of my buddies have cobalt SS's LT1 cars etc, cant be left behind since I just sold the Z......gotta make the daily driver keep up for the time being

a rocker car on a 3.4 will probably let you be able to run enough timing to get into the mid 13s if the person who tunes your car actually knows what they are doing. any off the shelf PCM wont get you there.

my car felt like a beast after i got it tuned and i was running LESS than stock timing. it was just the pure fact that i wasnt knocking anymore that made it feel faster.

1.84 Rockers, DHP PCM, 3.5", 1.9 60' and I ran a 13.8

Well lets see...stock blower, stock TB, stock cam, stock valvetrain parts MINUS the rockers...with a 1.898 60' time though

160* T-Stat
Autolite 103's (too cold of a plug...but meh whatever)
DIY Ported Front/Rear Manifold, wrapped crossover(It was a royal PITA)
3" Custom Exhaust, no cat/res/or u-bend
3" Shorty Downpipe
Custom CAI (had the filter OFF and the headlight out...not a good idea LOL)
ZZP 1.0 PCM
Yella Terra 1.84:1 Roller Rockers
TB Spacer/Heat Shield (Pointless Mods)
ZZP Poly Mounts
3.5" Press-On Pulley (with 3.4" belt...NO SLACK )
275/45/R17 Bullitt wheels in front might have helped my launch too...but it was about 65*-75* outside and I had a gallon of 108 in her too...

13.848 @ 98.72 mph Then it blew up LOL

Hopefully you at least won and got away for the end result lol

Anyone have any KR problems with the overkill pcm's?

Yup...only heard good things about them...just turn around is bad since he lives in Canada...

before we go any further, id like to hear that you value our opinions over ZZPs since...they are a business and like to make money.

seriously, what are you planning on buying at this point?

Well if it wasnt for everyone on hre I probably woulda ordered a zzp pcm I know that....next mods im thinking is going to be a pcm from overkill, then plugs and a pulley.

What are some other good mods that help fighrt kr? Anything?

yeah, looks like your exhaust is ready for some form of cooling. an intercooler would be a BIG step for you since youd be able to drop a bunch of pulley sizes immediately after you put that on.
