Ah yes Olaf Manthey, I forgot about him but thanks for reminding me of him. Another very capable man with a good race record too in the VLN events at the 'Ring. His place is nice and as stated not even around here do i see much advertisement of the Manthey product unlike Cargraphic and TechArt.

They problem is most of us with modified equipment haven't really done a dyno (before and after), haven't got enough experience to comment on reliability, deal with multiple suppliers, and can't make comparisons. In addition, I'm not sure what the purpose of the thread is ultimately. Is it to help people choose a supplier? IMO People don't want to be put in this position in a public forum.

I am happy with the stuff I've got.

 

Herr Manthey has insisted to keep his business small and personable. He has stated strongly that he does not want to become "a parts catalog supermarket "
Motorsports, word of mouth, repeat clientelle and all the other tuners keep the shop very busy. That is his MAIN form of advertising.

The purpose of this thread is simply...to learn and hopefully make an informed judgment as to who does quality mods.

For example, I'm contemplating an HP upgrade but only if such a "mod" is fully balanced with the overall performance and reliability of the car. If, for instance, more HP results in suffering lesser functionality or reliability in some other performance aspect...then obviously such a proposition does not work for me. In other words, who does the best comprehensive upgrade package? Is there such a tuner...who can take a $150k car and say here's a mod package that you can reliably live with for the rest of the life of your car as originally envisioned by Porsche? Drive it on the street, track, easy or hard and you won't have any CELs, blown MAFs, etc. etc.!

Hence calling on all tuners and non-stock Turbo owners...

 

How much do you want to spend?

 

$20-30K is not unreasonable...the key is what does one get for it?

 

Then Ruf....

 

... if your looking for a short shift kit and a set of wheels.

 

Dock, you don't recommend your stage 2 GIAC setup?

Rather than naming tuners I would focus on what is done to it.

You want longevity and reliability and have that kind of budget, make sure you get a package that keeps you within around 1 Bar, and includes at a minimum cams, intercoolers and turbos. Make sure you see a before and after dyno chart as a sine-qua-non condition specifically on your car. Check the smoothness and growth vs. stock of the curve in the 4-6k RPM area and make sure you see AFRs and boost for that RPM range on the same chart or datalogs..

 

I'd say its simple given what you want...RUF.

 

Yes, I recommend the stage 2 GIAC. But if I were planning on spending 20-30k, I'd spend it on Ruf.

 

Attnoc, I have always repected your opinions. I am thinking of some engine mods for my 03TT. Why specifically would you spend the money on RUF engine mods? I am trying to decide if I should spend the money on RUF or go GIAC.
Thanks Doc.

 

My answer was based on cost not really being the issue. If I were just looking for ~500 hp, I'd go with the GIAC product. Above that power and with the money to spend, I'd pick Ruf because of their ability to provide consistant, reliable power.

 

Thanks Doc for your help thus far.
I now undestand that RUF is the "if money is no object" choice. However, does RUF 600+ hp versions provide the same reliability and driveability as the 500hp version. I guess one of my questions Doc, is at what point in modding the engine do you loose reliability and drivability, or does the RUF modifications regardless of HP output give you the reliability and drivability?
Thanks Doc.

 

Just my take on the issue, but I think all levels of Ruf tuning are reliable, with good drivability. IMO, they just do world class work. Their modified Porsches seem bulletproof...
