You guys still want to put something together sometime?

Yup. Adding to the list:

• flat6pilot (Kyle)
• 16volt (Shannon)
• kenikh (me)
• Mark Houghton
• pkabush (Paul)
• cnielsen (Chris)
• rswannabe (Brooke)
• zakthor (Eric)
• cnielsen (Chris)

Although my car, Paul's car, Shannon's car and Brooke's car are all apart right now. :P

For headstud replacement?!?!?! :eek:

Youse guys finally pulled yer heads out of yer collective keisters?!?!?

:D

Grr... I'm still at least two months out.

Damnit you guys! Aren't you supposed to get your projects done in the winter?! :p

....you must think about Chris a lot, you have him on there twice.

Epic burn. :D

Track Day Test
 

So I took the car to the track this weekend (The Ridge Motorsport Park in Shelton, wa) to open her up.

The first time at the track with the turbo I wanted to be able to turn the boost down to a much lower setting than what it was dyno'ed at, thus the reason I installed a MBC with a .3 bar spring.

The .5 bar spring netted me 360whp (@ nearly 10psi). I don't recall the rule of thumb on hp/psi increase/decrease formula is but with the MBC at it's lowest setting, it'll give me about 7.5psi (or closer to a 'true' half a bar of boost).

The conditions were a bit wet and I wasn't comfortable 'pushing' to the edge.

The video below shows my quickest lap of (the before) 2:04 in hot, dry conditions while chasing another, faster 911. (Mark Albrecht) While my lap in the turbo was a bit slower (2.05.xx) (I got hung up on T12 trying to pass) I'm still learning how to feather in the new, available HP.

It's still entertaining to watch the differences....

How do you like that track? Car sounds great with nice smooth power!

Track is great! Can't beat freshly paved asphalt. Lots of fun ups and downs and a blind corner or two.

Mine's apart for complete rebuild due to shattered rings on all 6 cylinders. That's what you get with high compression, high boost, single plug.

That sucks. How high were you boosting it?

When I bought the car it was running 1 bar boost on 8.5:1 compression on single plugs. As soon as I bought it I dropped boost to 0.5 bar, but I think the rings were already shot at that point. I did not have a leakdown done prior to purchase, so that is on me. It was an impulse ebay buy.

Okay that makes sense. I bar wont leave much room for error on that motor.

Pretty much limits safe driving to winter days

This is my new FAVORITE THREAD!!!

Answer: 14,000 miles and 8 years. That's what it took to finally lose compression on #6 cylinder turboing a N/A engine.

Bittersweet.

The rebuild will start this fall. I've talked to Chris at Turbocraft about recommending a build that might handle 500hp but tuned to 350 - 400whp for track days.

I may have more questions in the coming months as I create the parts list.

I think you set a new standard with your build, and that what inspired me to turbo my euro 3.2! .. mine is still doing fine after about 1000 miles (no tracks so far), but since these engines became VERY expensive and I'm not rich by any standard, I decided to also rebuild mine to be more boost friendly, my plan so far :

- a very clean used set of 3.3 p&c
- a used B&B full bay intercooler
- a used Haltech 2500 ECU
- a used 997 DBW throttle body with the matching pedal

all of the above item cost me $2750, I think that would be a cheap insurance to keep my engine happy and get a bit more HP at the same time.

Good luck with your project!

Current rough build ideas (Notes from Chris at TurboKraft)

Goal is somewhere between 400-450whp. (Build the engine for 500hp and tune it down)
Some track duty (3 -5 times a year) but no racing.
Ultimately something reliable for the reason above. HP goals could change if unrealistic but also with reasonable cost in mind. I don’t need to chew up anybody on the street.

• P&C
Good: Standard 3.2L big bore Mahle Motorsports P&Cs
Better: LNE Nickie cylinders (allows knock sensors) with custom CP Carrillo pistons w/ 3rd party coatings

• Rods
Good: Rebuild original with new pin bushings, ARP bolts
Better: Pauter forged 3.0L Turbo rods

• Cams
Probably SC cams (supports up to about 450whp) 964-family cams are also an option.

• Heads
Upgrade valve springs & retainers, guides. Ideally port & polish to match the Carrera manifold or as close as possible (40mm is practical; full 41.5mm means welding & machining) Will likely twin-plug.

• Turbo
I'll run what I currently have.

• Miscellaneous
Bigger oil pump (964 pump?) and crankcase squirters, ARP head studs or 993T or Supertec (not Raceware) Fully refurbish the crank, i.e. machine out the oil plugs to truly clean it. Update from Megasquirt II to III ECU, larger intercooler, CoP ignition.

Followed this al the way through, fantastic results and your budget was impressively done. I bet it's a blast to drive with the current power/weight.
