A couple of years on from her original EVT700 build this car came back to us for a hardware and software update with EVOMS' latest EVT775 upgrade, including the dual-mode ECU for 91/100 octane (the switch is hidden in the ashtray). Since then she's also added a set of TechArt GT Street Side Skirts and all-black 19 inch HRE 893R wheels.

Off comes the bumper..


From the other side you can see a few suspension goodies including the TechArt coil over kit and many solid links/bushings.


And the Tubi Race Exhaust system:


The parts start to come off..



Out comes the airbox and standard throttle body:


The factory plenum vs the larger Werks1 T-pipe kit:


Werks1 Kit installed in order to accept the larger 82mm throttle body kit:


The factory inlet ducts are indeed quite skinny/restrictive and to feed the upgraded VTG turbos we installed the EVOMS Turbo inlet duct kit (driver's side shown):


And installed:


And other side:


The smaller 997TT throttle body (left) vs the larger 997GT3 throttle body (right) ready to be installed:


The stock pulley is also removed:



And the EVOMS lightweight pulley kit installed in its place:


A box of take-offs including the stock coil packs, throttle body, plenum etc... These were all replaced with EVOMS' HED Coil Pack kit and upgraded spark plugs:


James installing everything back together:


Here we are with the ECU/DME open and installing the necessary EPROMS for two fully-functioning ECUs. The EVOMSit software is then burned to each EPROM.


A switch was run to the center console ashtray for 91 or 100 octane modes:


Ready to go for a test drive:


Ready for pick up...

 

Wowzer

 

Beautiful...excellent work again!!

 

how much lighter is the evoms pulley vs oem pulley? did you measure?

thanks

 

We did a long time ago and I'll do it again on the next one (next week) but it was only about 1/3 of the weight of the steel factory one (it's smaller too).
Thank you sir!
Cheers!

 

Awesome install Alex!!

Do you have any data as to how much faster the 775 is than the 700?

 

Alex, thanks for the answer. you have a pm! (in a minute)

 

Danke... and I remember when it was developed on Subbie's (another customer of ours with a great white!) EVT700 late last year Todd did the live tuning on it (see dyno) and some other testing. I can tell you having driven them (sadly always on pump) that the car is _breathing_ better if you will. There's certainly less lag than before. Very responsive for a TT (seeing as I'm all NA these days) actually. The pulley has some to do with that too obviously.
Thank you and right back at ya

 

Beauty!!

 

Whats with the 'she' stuff...HAHA

Thanks for fitting this in your schedule, the work is second to none! Cannot wait to pick her up...

 

Nice

Nicely done guys...

 

Nice work.

 

Thanks man...
Danke!
Cheers and these are the original EVOMS clubsport intercoolers from 2007-era and about 33% larger than the OEM GT2 core.
We dig it too... I was glad to see white really take off on the TT side for the 997 series.
Haha I'm not sure... He certainly had a sex-change OP this week:P As always our pleasure and please take it easy on Kermit next time you're along side her ok
Thanks!
