Project Pineapple Express - Build Update V.3

I'm excited to say that the next revision to my car is finally underway at AIM Performance NJ (www.facebook.com/AIMPerformanceNJ)

Here is a quick recap of what has been done to date:

Starting Point:
  • Purchased December 2013
  • 2002 996 Turbo w/ X50 package
  • Eurodyne Tune
  • 5 Bar FPR
  • H&R Springs
  • 997SSK

V1:
  • Completed February 2014
  • Custom Exhaust, Tune Refresh

V2:
  • Completed February 2015
  • K24/20 Turbos w/ Clipped Wheels
  • Custom headers w/ PTE 46mm external wastegates
  • ProEFI 128 w/ FlexFuel Kit
  • Custom Y-Pipe w/ dual BOV
  • Walbro 460, Bosch 044, 1400cc inj, upgraded fuel rails
  • Updated X-Pipe Exhaust (added mufflers, new tips, and plumbed the wastegate dumps into the system)
  • IPD Plenum
  • 997.1TT Intake manifold
  • Pinned coolant pipes
  • ERP Twin Disk Carbon clutch
  • GT2 Slave conversion
  • Forge boost hoses
  • AWE Intercoolers
  • RWD Conversion

V2.1:
  • Completed April 2016
  • 997TT Rotors
  • Hawk HPS Pads
  • Torque Solutions Engine Mounts
  • Torque Solutions Transmission Mounts








E85 High Boost Map



PLANS FOR V3
  • Build began May 2016, Est. Completion June 2016
  • Transmission build (GT2RS gears, strengthened components)
  • WaveTrac Differential
  • Engine build (rods, bolts, gaskets, rod bearings, head refresh, head porting, 997 lifters, valve job)
  • Welded coolant lines
  • Custom tuning by TurtleTooned.com

GOALS FOR V3
A very reliable and drivable platform that I can cruise around with and take to the half-mile events when I want. First and foremost I do not want to give up the drivability of the car as I take it to work every day in the warmer months and make weekend trips frequently.

I am not upgrading the turbos just yet (unless someone wants to buy my existing set). The built motor/trans will allow me to have the peak power I have now across a wider rev/gear range, without fear of damaging the internals.

Got this from Joe at AIM Performance on Friday night

Very nice, I almost feel like I'm right behind you too! My car is at AIM as well and Garth is tuning it. 656whp on pump so far, also with a 128. E85 coming! Did you have issues that pushed you towards building the trans or is this just preventative? How thick an intercooler? I'm still on internal gates and tuning them has proven touchy but I really don't want externals

b/w 7163 turbos have internal w/g to 40 psi!!

dscoff looks like a killer build!

Ya ya, if these turbos aren't doing it for me EFR are at the top of the list for sure. I want to see what the dyno curve looks like and log boost response. The dyno plots above will be helpful for sure. Boost just can't be ramped right now till after torque peak.

Thanks man. The transmission decision was two-fold. I was experiencing issues with 1st gear popping out now and then from a stand still, and also sometimes had difficulty getting into 3rd at WOT. Once I did the tras/engine mounts the 1st gear issue got worse as there was much less movement.

At this point my options were to rebuild to stock spec or rebuild with use and power goals in mind. The benefits of going built were: added piece of mind, longer gearing, and what should ultimately help me stay at my goal of a perfectly streetable car with less chance of having to have it down in the shop again.

You made 764 to the wheels on stock rods?

Torque is what you need to sweat most is my understanding. Once past torque peak you can increase boost as octane allows and make a good bit more power if the turbos can breathe.

On my car the same thing is being done, low boost until past torque peak and then ramping up to push power up top. Makes for a higher peak number but area under the curve is far lower than it would be if rods were already onboard and the turbo turned up down low. Make sense?

Fikse Profil 10 or FM10 (don't remember off the top of my head). ButziGear is the man to call for wheels, he knows fitment on these cars inside and out.

Yes, but that is on the high boost E85 map which I've only used maybe 10 times. The boost/torque is controlled to peak at 764, while staying safe at lower RPMs. Off the top of my head it graduated from 18-28 PSI.

Once its done I'll be at all the Bergen C&C and SlipStream 1/2 Mile events.

Thanks, that explanation basically hit it spot on.

The silver 996? I didn't hear it while it was there, but it looked good (if I'm thinking of the right one). I also saw a few other 996TTs while I was there last week.
