Great project!

Just curious guys...are you working with europipe on the exhaust or a you simply modifying a europie to your standards?

Keep us posted!

 

We will be @ VIR next on the 23rd of July.

We have a very long standing relationship with Europipe. All of our "turbo" cars have Europipe on them and they are always the first we recommend to anyone.

 

Hey Casey

We can't wait for final results but ur dyno act strange with GT2....what's the reason??

We dyno 2 stock GT2 and they made 490-500rwhp and after flash, exhaust, Dv's and airfilter we saw 580-590rwhp.

BTW...We tried ur modded 997tt VTG's and I/C's on 6speed 997tt and they work excellent

60-130 ran 6.5-6.6sec on pumpgas!!!

Can't wait for modded GT2 VTG's!!.

Keep update us

 

The dyno didnt act strage. you can see that the car made significantly more power after we put it back to stock! This car will be a lot of fun and we are looking forward to it as well!

 

few updates... Ran the Europipe exhaust for a few runs and it made some nice mid range gains... But in order to give everyone some good options we are going to continue development with the stock Akrapovic exhaust for the time being and after we get our turbos installed, install the europipe back on and measure the gains...

These two pics show our 127mm Blitzkrieg intercoolers installed.

 

Your efforts on a 997GT2 have piqued my interest...

I checked out your site and saw your "worlds fastest VTG" 997tt with the curves below:



A couple of questions please ?

I have seen other US tuners showing maximum torque also at this 4200rpm level using conventional non VTG turbos so what exactly is the advantage of using VTGs if the torque doesn't peak until 4200rpm ?

This engine with its 770ftlbs/1047NM is built with carrillo rods - am I correct ?

 

Toby, good to see you here!

Our goal in building high horsepower cars is to keep them simple... Through our decades of pro racing with porsche we have always found that staying simple is key and always fastest.

We have continued VTG development as we feel that it is the "OEM" Option... we dont have to cut anything up, we dont have to add external wastegates or modify the stock oil lines. Look at how our intercoolers fit... They dont require any modification of the factory tubing and retain the clips that the stock pieces use. Porsche did an incredible job building these cars and we arent going to reinvent the wheel.

Keep in mind that the dyno is done at full throttle, it doesnt show part throttle or the power the car makes on initial throttle tip in. These VGT cars have incredible drivability!

This GT2 is going to turn great lap times in a few weeks down @ VIR and I will be providing IATs just for you

this is a stock block car.

 

Good to see you here too

I like the VTG philosophy, they are the core technology of the latest Porsche turbos and it is good to see you persevering with them.

FWIW for the biggest VTG RS Tuning use which produces engine dyno ~740PS they specify 3.9 litre conversion, they say this is needed to produce the "correct" power curve - hence why your curve may well be accurate for your oversized compressors ?

This is really for the punters out there reading - you are running 1047NM peak on stock rods ? I have a set of Carrillos arriving tomorrow as at my torque level 827NM @3000rpm engine dyno, there have been a number of failures in Germany, and not pretty failures..... I'm not sure what this means but I guess a combination of over zealous measurement of peak torque by a spinning set of rollers, not as big a loading torque spread (ie mine runs around 800NM from 3000rpm to 7000rpm) and probably cars not being run as hard as is possible with no speed limits ? Whatever it is, it sure is confusing for the punters, and believe me I have no desire to have my engine stripped for this expensive work

 

Getting further into this... Just made a pull at 620whp on pump fuel on low boost concentrating on massive mid range and high end...

While we are working on a few other odds and ends we have begun swapping out the ceramic brakes for the steel pieces off of a new 10/11 GT3 RS.

Pics...

 

Sorry for the noobish question, but why are you swapping out the ceramics for the steel brakes? Aren't the ceramics better in every way?
