My car is 100% stock, but the GTS has some bits that make it very similar to a 3.8S with the oem Powerkit.

 

The GTS is a DFI car, the supercharger can't be used on DFI cars.

 

I have an 997 s with the vortech v2 and yesterday I had a race with a 997 turbo APR.
The different was to high.
This car is really fast.
My car has 372whp and is real power.
I also had a rolling race from 50km with a 997 gt3rs mk1 and I won him.

 

Doctor911 please clear which was faster? Your S/C 997s or the 997tt?

 

The 997tt was much faster but it was 620hp.
With the gt3 997 mk1 I was faster with difference.
The kit here in Greece is not 510hp in the dyno.

 

Even with 510hp you can not beat a 620hp turbo. What dyno do you use? Btw i am from Cyprus!

 

Γεια σου πατρίδα!!!!!
The dyno is roto test and you can see the real power at the wheels.
Even with this power that I have in my car the car is totally different.
Is very fast from the beginning.
Now I want to upgrade the vortech v2 with the change of the impeller.

 

Γεια χαρα!!!

So originally your kit was designed for less than 510hp so you will upgrade? What other mods do you have on the car?

 

No.
The kit is exactly the same with the kit vf510.
I have also have ipd plenum Cargraphic,manifolds milltek ,cat HJS,exhaust Cargraphic,short shift and ECU made at the dyno.

 

With those mods you should have seen 500hp at the dyno. Who is tuning your ECU?

 

The ecu is Andriamakis.is very famous in Greece.
His dyno is very tough.
The dyno s in US are very optimistic.
In his dyno the gt3rs mk2 has 354whp so as you can see me kit is faster that the gt3 rs.
The torque in me car is 49.7 kgm at 5730 and the power is 372whp at 6300

 

Your torque seems to be correct. The VF kit indicates a fixed power gain figure, so whatever dyno you use, you have to see the correct gains but with different total bhp figure.

 

I know that the torque is correct but as you know the power is different from dyno to dyno.
When I spok with a person here in Greece he told me that the the kit that he took from the vf engineering was not 510hp but 420hp at flywheels.

 

Looks this race.
The porsche has 420bhp.

 

If i was you, i would have tried the car on an optimistic dyno such as a dynojet just to proove their numbers are wrong. Anyway i am waiting for my VF510 kit and for sure i will check the before and after on a Dynojet and a MAHA dyno.
