You two just can’t resist being negative Nancy's around here.

Who cares how "rare" these customers are?

Murf has sold more than 80 kits, Carl who knows but I know it's quite a few, DR sold a bunch of twin screw kits, and John has a few out there himself.

On top of that all the strokers Greg Brown has pumped out.

The domestic V8 swaps are not exactly cheap either, more and more of those are showing up.

If anything, as word gets out outside of the 928 community that performance like this is available, the more interest will be generated for the 928.

Bottom line is some people want a stroker, some want a blower (of any kind) and some want a turbo....some want both or a combination.
Meanwhile others want a pushrod......
Money and overall cost is not the #1 driving factor for everyone. If it were, owining a 928 at all would be a stupid idea from the start.


Mindblowing really.....the 928 gets some positive press and you two still find something to be negative about. Brilliant.



That BMW comparison doesn't fly here, apples to lug nuts...... If the 928 was still in production and interest in the "older" cars was falling in favor of the newer ones, it would be a valid comparison. If anything the BMW comparison would apply when comparing the 32V 928's to the 16V. Most with any interest in making a high performance 928 will just start with the 32V version which shows in the available products from our vendors, very few performance options for hte 16V cars.

 

The pain to write a $ 12 k check only lasts short, but the pleasure of a TT 928 is lasts a long time. I have long forgotten what I paid John Kuhn. He designed the best TT kit I have seen, and experienced.
Considering the cost, I guess it makes a lot of difference if you can do the work yourself. But if you can, $12 k to get an extra 200 HP (easy) is a cheap way to get a real super car that can hold itself with many new model high performance cars, even by today's standards.
I probably have a total of some $33k in my 928GT, drove it about 17k miles without any problems. You can not find a better performing car for that kind of money, IMHO.

I would love to have a TT 928, and the $12k isn't the hold-back. That's just the initial down-payment, and it's way cheap. I'd need to have a non-original car I wanted to sacrifice, but again that's not big money. It's the costs after the TT work is done. I like everything to work, so my donor car would need to be brought up to current standard or at least brought back to original standard as far as suspension/brakes/etc. Then the cosmetics, a very $lippery $slope. Then 'consumables' like tires; Miraloma in front of 928 International has been repaved with rubber a few times over the years with Bill Ball burnouts, Rob E ABS checks and the like. Perhaps the most important "consumable" is the time I'd end up spending on it to get a few 'more' ponies out of it. I promised myself I wouldn't go down this road with the 928 I have now.

But with all that in mind, wouldn't I do better to just find a nice factory-supercharged AMG something or other? Certainly dollar- and time-wise.

 

I was only agreeing with finding people to buy this stuff is hard. Not that the cars themselves aren't awesome. I have another friend that does a lot of Toyota and Lotus Elise turbo stuff. He stopped working on Elises because there is a very small market for them. He's now concentrating on Evoras. (They also need the extra power a lot more).

People willing to spend big money on cars tend to spend it on cars that are made in the last 5 years. The money guys are spending on turbo/engine kits for GTRs, 911s, Gallardos, and R8s makes the 928 stuff look like monopoly money. Look at EVO MS. http://www.evoms.com/category_s/2337.htm That's probably $200,000 of parts on top of the base car.

 

The correct answer is, of course, to do both! In addition to the Kuhn TT, our family has two biturbo AMGs and one more on order. Reminds me of the Annie song: It's a hard knock life... ;-)

 

MUCH..MUCH nicer job on the intercooler intakes. That was my only "complaint" about the way the system looked. To put so much time and effort into it and have a riveted black grill added to the bumper was...

John does great work.

 

Still waiting for my Pano. It'll be nice to see some 928 content.

 

I've seen this beast and had the pleasure of foolshly trying to keep up with it at Spring Fling. Peter, you did some beautiful work getting John's TT sandwhiched in there. I've never seen a 928 takeoff from a standstill like yours. Hope to see you next year at Spring Fling.

BTW, a big thanks to Pete Stout for putting this story in Pano. He came through like he promised.

 

Got my issue today also. Ill read it soon... happy to see a 928 article as I flipped through it. More please~!

 

Some of you guys act like Tuomo's car is the only car John has on his plate. When I was there two months ago he had the car in the video that Tuomo posted and then another that he was getting ready to start as well. This isn't a mass produced, off the shelf cheap turbo kit. This is a well thought out, hand crafted turbo system. With every new build, going all the way back to John's 16v days, the system is refined and improved. Every new client benefits from what was learned in all of the previous builds. Tuomo's car has been a great test bed to push the envelope of the system. People are lining up to get these systems and now that the word is getting out through Panorama, that line's going to get a little longer. When I started coming to Rennlist back in 2004/2005 we were in the height of the turbo vs SC'er debates ( wars ) . There were some really great discussions and arguments back then. John had a vision and he has seen that vision through to fruition. I tip my hat to him. This is great press for the 928. I hear that Magnus Walker is looking at getting into a 928.....maybe even an outlaw twin turbo.

 

I'm happy to see these kits selling. I love turbos and his fabrication work looks very good. The prices seem realistic as well for the amount of work and what the hard parts cost.

 

As someone who has tried to develop a turbo system for my 928 I can say with great certainty that I would have been far ahead of the game if I had just sent John a check and waited for a box to arrive. The amount of time and effort that you spend engineering seemingly mundane items like brackets and plumbing and getting everything to fit in the tight constraints of the 928 engine bay are huge.

 

I'm finding the exact opposite of what Em00oo posted, more and more well heeled customers are buying these cars and doing with them what they feel like doing. So I agree with you Eric 100%

 

This last year I am getting strong indications that due to the rise in 928 values that owners now think it worth spending more money on them.

When I started working on 928 electronics in 2002 I thought demand for my services would fall away over the last 12 years. The opposite has been true.

It been a pleasure to have worked with JK during those years. His TT development is outstanding.

 

Don't forget about Victor and his S/C setups. There were 2 S4s with them at the Dubuque GTG last summer.

And Victor was just about drooling when he was describing how much he'd enjoy developing a Euro S2 version (he offered to do my car as a prototype at a discount).
