Title says it all. I didn't want to get hosed in another Schwitzer slowdown, and although I was waiting for Buehn to get back to me, homeboy apparently is really busy.

So, I have some factory perfect K04's in the mail. I'm looking for someone to crank these open and slap in bigger guts.

That said, does anyone ever have these bored out and do that work themselves? I have a shop up here in Boulder I've used in the past that rocks on stuff like that.

Any ideas? Thanks in advance.

Back to the garage,
Bob

give 'em to me

I figure I'll line up the stuff in the undercarriage and then work out the "top of the engine" stuff, i.e. software and fueling. I just want to make sure I can get the highest performance (within budget reason) I can from the hard-to-install componentry.

Randy at der Autobahn does GIAC, and I'll likely set my junk up with whatever reg/injector combo GIAC supports. I am honestly unfamiliar with the whole deal, for instance, say, if the Bosch greentops are the same as the RS4 setup that, say, AWE has... I just don't know that tech yet.

Wagongotya - I will make you a smoking deal on some lightly used K03's. Bonus - deer collisions are a thing of the past with their high pitched whistle.

if you're looking to get high performance from your hardware a good set of IC's and DP's are pretty important in keeping IAT's down and the exhaust open...which = hp in most cases. You can't go wrong with either GIAC/AWE or ASP fueling, both are fantastic options in my opinion

and no avail yet.. they're working, but not running worth a crap... Hope you can ger yours to work!!!

I've heard that the K24's are hard to tune...

For reference, Buehn's product page is below.

make sure those big brakes get on there before those big turbos.

Get the job done properly.

But FWIW, you won't see much gain with K04/RS6 hybrids at this altitude over OEM K04s. Sure, some gain, but for the $ v HP amount, I don't think it's worth it.

....man, if RS6/K04's are that hard to tune, maybe straight up K04's are the ticket. I mean, especially, the hybrids are a chore to tune at 5000ft, it may be lethal to A/F at 10,000 ft, which is where my weekends get spent in the wintertime.

I had hoped that Rs6 tuning is past the dyno queen stage... maybe it?s not as streetable as I had hoped. Bummer.

I say this even though Cole says his car feels slow with the stock K04's. :)

the biggest problem is trying to get sealevel like psi out of those little snails. Once you accomplish a proper A/F ratio at 5K feat, then 10K will be no problem at all. You may run out of breath up there( as in not generate as much boost pressure) but the one thing you won't do is run lean. When I moved from San Diego to Denver I noticed a 15% reduction in MAF value readings. However I had more then enough fuel for that 15% reduction. Any well tuned setup is going to be able to adjust fuel trims off altitude (there is a nice little barometric pressure sensor in the ECU) and meter fuel out correctly. If anything at 10,000 feet, you'll be pulling less air, not able to compress as much air, and have more than more than enough fuel.

The risk in a turbo car for elevation is when you go back down to sea level, not up in the mountains, and your setup is running lean now.

My APR kit has had 0 problems here in Denver, or up in the mountains (I've vagged the car at 11K feet) and passed emissions with flying colors. If your setup is well tuned as it should be you shouldn't have any either.

isn't the "pickup" bio-diesel as well?

looks like an old military 5 ton, they run on diesel, JP-5, or JP-8.

I always like the great compatability of military vehicles with thier fuel choices.

...well, you're technically right, but I yanked the stock motor in that, put in a Cat 3208 N/A engine, found out that big NA diesels suck at altitude, so I made a mount/pedestal/oiler and an intake and turbo'd it.

BTW, it's sort of bio... every diesel technically is capable of compression ignition on veggie-based combustibles. While I run it on a mix of bio and dino in the summer, in the wintertime, it's straight dino.

The stock multifuelers, though, as stated will run on just about anything. The compliant injector pumps and fueling setup on those will allow a mix of anything except straight av gas, which isn't recommended for some reason (coulld speculate but not sure). Otherwise, I mean *anything* - ATF, waste kerosene, mixtures of old motor oil and diesel, or gas, or anything. In the end, it's all compression ignition. Intake air, compress air, shoot in fuel.


So, I wonder if I've seen you before Audi OS? There was an S4 that used to park/visit like 2 doors down, maybe yeah, a year and a half or 2 years ago.

I'm all flattered and stuff. I'd guess I'd be properly flattered if I weren't going home tonight to continue to get the front of that POS buggy off jackstands. :(

Please pass on my contact details to them - racecadet at yahuuuu if they'd be open to share their experiences.

Thanks again,
Bob

I had the blue FJ40/black KO4 1.8T that was always over there...

I always used to marvel at what you had parked in the driveway...

Do you still have the grand cherokee?

...I sold the Grand, my old F350, and my daily driver to buy the allroad. :)

I miss the hell out of that ZJ - beefed up 3/4T drivetrain. I fabbed all the suspension and axle work, the steering, the upgraded brakes (down to bigger booster and Master Cylinder, all junkyard mix and match), the drivetrain upgrades, the rear bumper, the hitch, all of it myself - I think I was one of the first 5 or 10 people in the states to put longarms on a grand at that point. But, after it sat almost unused for a year or so, I realized that I just never really drove it anymore. Too bad I'm not in my current relationship - I'd love to have it back.

Well, I do know that the Jeep's buyer enjoys it immensely, and that greatly pleases me. I told him to call me when it becomes too weighty to hold onto.
