Twin Turbo Video on Youtube
 

http://www.youtube.com/watch?v=9QSd_prPqoA

The throttle was never fully opened for any of these shots.

John,

I noticed in the video when the car is stationary and the camera is at the exhaust that the car shakes when you hit the throttle. Do you have fresh motor mounts in, or are they original?

If they are new i could still understand why the car rocks from all the torque.

Was just curious if you have new motor mounts or if they are original.

Not sure...I think they may have been replaced at one time. They were certainly not collapsed by any means.

I plan to do a better promo video soon...that one should have my mug in the shots.

Nice car. We need a nice burnout video :D

I'm not big on burnouts...but she'll do it for sure. Did you guys notice how RESPONSIVE the ball bearing turbos are. They come on boost hard and fast, no?

As you can see, the boost response of the system is totally acceptable!

This is the stuff you got banned on R-list for. Taking pot shots in other threads. Get over it Russ.

Kuhn, nice work buddy. See ya at SITM.

Then try to be a man, and not do the childish things you have done for the past week.

A laugh between you an another would be in PM's. Of which you enjoy saying thing should be kept as, instead of cries for attention and sympathy.

The pot shots on the thread you mention are between friends, in good humor, yours are in anger and envy. Enjoy your stay, I'll be here too, as I have been.

Is there a large group coming from Texas thus year? They always seem to be well represented. That show will be here before you know it...time is going by fast.

I'd better make more videos now!

Very cool!

You should bring the Alien to SITM!

what is SITM?

Sharks in the mountains....major east coast 928 show held by 928 Specialist out of Spruce Pine, NC.

What's the date for SITM this year. I'm sure it's been posted but I'm on too many boards and can't member....

PM sent----

enough of this.

--Russ

It's like the 6th of June...1st full weekend in June.

I was just surfing over on the list for info. Thanks!

John,
Looks like a clean layout.
Do you have any dyno charts, before and after, with afr's?

Griff

Very nice! Can't wait to see it in person at SITM....

Have you had it on a g-tech (or even better to the drag strip) yet?

Just saw this for the first time... Boy there sure was a lot of white smoke coming out of that tail pipe. How old are those head gaskets? Would hate to see all that hard work get destroyed... :)

I guess you are at it again Olson, Besides you will only see the ass end of the car only.:confused:SmileWavy

I really don't understand how the lot of you don't like this guy and his accomplishments. I can semi-understand the debate between types of superchargers. Should it be a centrifugal-flow, a twin screw... or maybe a turbocharger? It is all the same, forced induction. All of us have significant others, and they in the end are the primary determinant in what we do with our toys, our Porsche 928's.

Why the acrimony toward Herr Kuhn and his latest turbo system?

N!

who knows...it certainly isn't justified.

for a while there, I thought it was a sand box issue.....maybe some folks (not referring to John here) just can't have any critiques sent their way, but John has been pretty much over it for some time now.......

the complainers of what I have written in the past are the same ones who don't follow the rules per se, and then when someone makes a comment (about whatever), the response is "you don't know what you're talking about...." Unjustified as well-

if we all would just quit teasing, trashing, bashing and just plain stopped being mean to each other, the forums would be a lot better off>>>>>>>>>


all of this picking at each other has become very tiresome........:rolleyes:

Andrew, I do take it that you understand that one of the by-products of combustion is water vapor...
I'm convinced all the problems you have had as of late are caused by Bad Kharma.

Other than that I really don't have anything else to say here.

Cool car! What a lot of real work! Hat's off to you!

Whoa... I was saying this out of genuine concern. However, rereading my statement, I guess one could misconstrue it for some rib/dig at John, but that was not my intention (hence the smiley face...).

I had an issue with pitting on my head which allowed coolant to ever so slightly leak into my combustion chamber. I would hate to see something similar happen to this car. If that car was cold, I could understand the white smoke as a result of accumulated condensation burning off, but once warm it shouldn't expell that much except in the coldest of climates (e.g. Minnesota), and even then it shouldn't be that much. Hence my concern.

A simple explanation like "The car was was not fully warmed..." or "the HGs have already been replaced" or something of the like would have been a more appropriate response than an attack on me.

I love fast cars, no matter how it's accomplished - be it displacement, supercharger, turbo, NOS. Just saw a 650WHP Mitsubishi with a 2.3l engine running 30 psi. Simply amazing. Maybe someday I can get to that type of HP/L, but that's a dream for now. I digress.

We need to all work together and share information that we gain through our efforts to lessen the learning curve. It's kind of like that analogy of working together to grow the pie, rather than just trying to get the largest slice. By growing the pie we all win. It's a much more mature attitude.

For example I learned how to strengthen our stock TT shafts by 50%. I'm happy to share the information once this BS stops.

And as for my issues... and I have had issues, no lie there... they are a result of having a high mileage car, that had not been taken care of. I thought it was a bargain - no such thing. Bad Karma? I don't think so. I've done a lot for the 928 community and I go way out of my way to help people when I can.

I'd be happy to buy you a beer sometime if you'd let me and maybe we can bury the hatchet. What do you say?

Trust me Andrew, there are no issues from my side. We just want to surround you with turbo technology until you say "Uncle" ;)

We were going to dress "Sonett III" up in a Monkey suit and let him chase you around the show in June whilst carrying a turbocharger, but on closer examination I determined this would not be in good taste and that someone may end up taking offense to it all.

You buy the beer and I'm game, but I won't be throwing a blown head gasket into your shrine as I don't have any to submit!

Well then I guess you need to stop the BS Olson.

interesting......haven't heard of anyone breaking a torque tube (shaft). I've seen the couplers broken, clutches blown, transmissions torn up......and oiling problems with the engines, but no shaft breakage.

maybe.....it's the next thing in line for failure....?

No BS from me... :rolleyes:

A few people have. I learned that if we could drill a 1/4" hole in the center of our TT's it would be much stronger than the solid piece because you remove the fulcrum point (i.e. the center) and transfer the load over a greater area. The problem is we can't drill a hole that long without great expense.

The solution is heat treating. The factory TT's are not heat treated. The issue is that traditional heat treating (horizontal) will cause the the shaft to bend/warp which will cause considerable vibration at 6800 RPM. If you can hang it and heat treat it, you can impart 50% more strength to the shaft and gravity with help you to keep it straight. But it's not easy to find a place to do it.

Luckily the breaks appear to have been anomolies thus far, but eventually it will become an issue for high HP 928's.

HA HA HA . That is very funny coming from you[ the one that starts all the BS] Olson. That goes to show people how much of a man that you realy are. Besides, I am not going to go on with this game that you are playing. That's the way I see It olson.

when you look into the expense of it, and then match the cost of replacement to it, you might find it's not worth the effort......

I've got two complete torque tubes w/ good bearings in my pile of parts, and no takers. in this case I suspect it's just easier/less expensive to do a changeout of the whole tt assembly.

Maybe i should try that before I blow another one.

I have been following John and his progress for years. I saw the car at SITM last year and it is spectacular. His work is outstanding! I look forward to seeing his car again this year.

Glenn

Stop by Glenn...we can go for a ride. I didn't give any rides last year.

John,
That would be great, I will take you up on it!

Glenn

Why are you such a prick?? I offered a genuine concern... Oh why bother. This is like my eighth post on this board and I'm ready to put you on my ignore list (if there is one here).

Edit: Nope! no ignore list. Oh well. I guess I will just have to taunt you a second time... :p

Isn't the answer in the Porsche owner FAQ? ;) http://forums.pelicanparts.com/suppo...eys/paddel.gif


Use the "manual" ignore function, pay no attention to negative off topic comments and say what you want to say.

BTW I have a Kentucky long rifle with a barrel drilled by hand over 100 years ago, I sure hope mechanic skills haven't dropped that much since then. OTOH I am not really buying the drill a hole and make it stronger stuff. Besides axles will break before the TT does.

Hey Olson taunt all you want,that just shows everyone how much of a"boy"you are!:)
