Re: D16Z6 makes 250whp 203trq st00pid tuned!
Thanks for the compliments on the setup and all.
So far it has been just about 2 weeks now and this setup is still running strong (he doesnt exactly baby the car either
).
Ivan has just got another d16z6 short block that we are now working on building up for him.

And, no Spenser, it's not your rings either. They just go first under light pinging...

HA GEEZ!!!!! Everyone know's it's not psi it's whp. However, you don't know TRUE whp unless dynoed not guesstimated. Not everyone can dyno hence why everyone asks for psi instead. 250 whp does seem to me like breaking point on a stock sohc. Let us know though. Bump to the top for some more pics and vids please! I want a vid of this thing badly. Thanks!

I asked Ivan and he said it isnt a 60 trim on the compressor wheel, he said he doesnt know what it is but he knows it isnt a 60 trim.
So far it has been more than 2 weeks that this thing has held together and he has made roughly 8 passes at the local 1/4 mile, along with daily driving it to work.
Rember I am no special engine tuner, I am a fabricator, we left the tuning for a professional tuner Jason who knows what he is doing.

Sorry, to bump this so late, but just to add to the discussion about what will break the engine.. Two things generally break a healthy engine, cylinder temperature and cylinder pressure. By keeping the cylinder pressures and temps down you can have a high hp stock engine last a long time .

Translation:
He says to bring your power (boost) in after the engine's natural torque peak. Average cyl pressures are lower but the fact that you're turning the engine a bazillion times a minute means more horsepower is produced. Since time available for the combustion event is a function of piston speed, and time is also one of the biggest factors contributing to pre/det, you also gain a large dose of knock resistance by spinning high rpms.
However, those of us boosting low buck low revving swill are utterly fucked.
:P
Okay, maybe not, I just felt like being dramatic. There is also a general trend with parts weakening as temperatures rise, *especially* with aluminum. If you can keep the combustion temperatures lower, parts are a smidge stronger, and can deal with more pressure. Especially if there aren't any pre/det pressure spikes. Water injection or (less preferrably/ideally, although it's free and doesn't have to continually be refilled) EGR cools combustion temperatures greatly while producing more pressure. This protects the defective aluminum swill in your engines such as pistons and cylinder head, and leeches away pre-ig causing hot spots where they are most prone to form such as on valves and piston flycuts near the edge of the Honduh cylinder wall. Stock sleeves are still garbage, although it's looking like judicious block pouring can sidestep this to a certain degree.
Nice to see you here, st00pid!

Re: D16Z6 makes 250whp 203trq st00pid tuned!
First off the pics. arent working for me
How fast is he running at the 1/4 with that setup? and did you guy's leave everything stock(ie. Head gasket, Head studs) or did you replace those prone item's first? I was once told that the D-Series isn't gonna survive at anything over 220 WHP due to the rods being so weak. Any help on these Q's or more info on this setup would be appreciated since I'm lookin to put 10psi through my Z6 "Daily" driver and cannot afford to blow crap up and have down time. Now go out and get some more pics. and vid's. up! (after responding to this of course)
