UPDATE: DYNO RESULTS ADDED





________

I've spilled bits & pieces across the forum, but I'm finally taking a few minutes to log everything in one place.

Starting Point: 2002 996 Turbo w/ X50 package, Undercover catless x-pipe exhaust, eurodyne tune, 5 bar FPR, and H&R springs





Goal: I didn't necessarily have a target number in mind, but the overall goal here is to create the "ultimate street car." That means different things to different people, to me that is reliable, drivable, comfortable, and hella fast. The car also needed to be in a more competitive state for the various roll-race events. For 2015 the focus will shift to suspension & braking.

Planned Upgrades: I went to Garth at Undercover Performance for everything. He helped me put a plan together that would accomplish my near-term goals while keeping things ready if I want to jump to the next level

• K24/20 Turbos w/ clipped wheels, ceramic coated
• UC Fender Well Intakes
• ProEFI 128 EMS w/ E85 support
• UC Fuel System Upgrade (Walbro 460, Bosch 044, 1400cc inj, UC fuel rails)
• Updated Undercover X-Pipe Exhaust (added mufflers, new tips, and plumbed the wastegate dumps into the system)
• UC headers w/ ext. precision 46mm wastegates (ceramic coated)
• IPD Plenum
• 997.1TT Intake
• UC Y-Pipe w/ dual BOVs
• Welded coolant pipes
• ERP Twin Disk Carbon clutch
• GT2 Slave conversion
• Forge boost hoses

Status: I stopped by the shop yesterday and we are almost ready to hit the dyno for tuning. My exhaust and y-pipe will receive their final touches this week and I'm hoping to finally pick up the car sometime next week.

Here are some pictures of the journey:

 

looks awesome, awaiting results

 

Nice welds, nice looking fuel system mate, I have booked seats for this !

 

Nice setup. disregard the question. i was reading from my phone didn't see who was posting!

 

awesome re-build. congrats. you guys on the east coast get all that downtime to refresh your cars i'd suffer withdrawal symptoms

 

looks good. subscribing.

 

Sweet man looking good!

 

Yeah he's been without for months!

Congrats! Can't wait!

 

Trust me, I have withdrawl symptoms. I'll drive my car year round, unless there's snow or massive amounts of salt out

 

i know you do, bro. adrenaline is a chemical hang in there lol..

 

Like a glove

 

Nice build, man.

Is there a benefit to externally gating hybrid K24s? You don't hear of that being done very often.

Looking forward to seeing your results!

 

i found the answer to this first hand. initially i had internal wastegated 3071 turbos. while garth was tuning the curve was erratic as all get out. i found out the turbos are spooling faster than the wastegate's can keep up with. the external w/g allow a smoother faster transition and the curve was a smoother better line
it also allows for more boosting in the future whether on his current turbos or if he decides to change out to bigger. for me I'm only on 14 psi springs. i do have the ability by adding springs to bump the w/g pressure to 25 psi on these w/g. more psi will require bigger w/g which can be installed in minutes and these put up for sale

 

so this is why some of you guys use the bov's? always wondered the difference, and where/how it became apparent.

 

blow off valves (bov) to allow pressure to be released when shifting or releasing the fuel pedal
wastegate's are used to control boost. 2 different animals
