This car will need about 70hp less to reach 200mph than a stock 993TT. This means that with a 533BHP engine they can achieve that speed with the same output of a 600HP 993TT. When you factor the lower boost needed to reach 533BHP instead of 600 and the resulting reduction in heat soak, the HP differential can be much more than the theoretical 70HP, you have a very substantial increase in acceleration by working on aerodynamics.

The other advantage is obviously longevity of the engine if the car sees frequent high speed drives, the other is mpg.. In the long run, maybe cheaper to go this route?

Thanks

It fits like originally from roof and side walls. I have to "only" make new lower(front edge) support/frame for it. The new sealing rubber/frame comes with glass.
Of cource there are also some "minor other works" like cutting the front lid and install new windscreen wipers - they don't have to be those ugly "single one wiper upwards" -model..

I truly hope you do manage to fit one to a "Porsche" finish and really look forward to updates (pics please ) on this one

Are there any 993 based car on the whole world which has that "911 special windscreen" installed?
All cars what I have seen with that mod done, have been 964 or older model..
So does anyone know?
I like to have a picture how they did it nicely.. and is my car the only 993 version now..

dp say it is "not possible" on the 993tt. I have seen a silver 993tt at RS Tuning which had the screen conversion. This 993tt has stock body with tts spoilers, stock wheels with 5mm spacers and a Secan EVO1 (MAP) high 600hp motor in the back. I didn't get any photos, sorry.....
RS said they would not consider doing another one on a 993 even for an EXTRA 10K Euro on the bill ! - so it was obviously a major PIA to get 100% to Porsche standards.....
Keep us informed

BTW PIA = pain in the *ss

DP has also silver windscreen modified car, there

but you don't mean that one which was at RS tuning ?
Any close-shoot pictures?

So now I have learned what that PIA means literally

Then when I told them I had SEEN a 993tt at RS with the screen they replied:
It is correct that Schmirler has used the sloped screen conversion. They have worked hard to make it fit as you said

No the RS one was a different car..... Sorry no pics, I wish I had taken some
