Got it Mapped!!

If it's 450 at the wheels then it most likely a 3076 ( aka GT30R )

How the hell does that pull from 2k?

Be very interested to see the spec of this turbo!

Excactly my questions too

[DJones]

Dont know the answers, may be input the wrong weight??

To be honest im not that botherd what the bhp is i wanted the torque and boy have i got it, its savage.

[kwlw]

Which GT30 as there are numerous trims? Have you got the full specs mate?

Turbo uses KKK hot side and Garret cold side:
Some details of the GT30 turbo from Turbo Dynamics:

- Turbo Dynamics MD357: Special 0.6A/R turbine housing to take Garrett cartridge. High flow GT30 compressor wheel, 0.50 A/R T04E modified compressor housing and seal plate assembly, compact GT25 angular contact roller bearing core assembly, left hand thread GT30 low inertia shaft & wheel assembly. Max boost 32 PSI.

Compressor:
- 0.5 A/R T04E housing
- 48 trim
- 52.8mm inducer diameter
- 76.2mm exducer diameter
Turbine:

Ah thanks Sau

It's a proper hybrid turbo alright! it's based on a 3076R but with a smaller 48 trim on compressor ( standard 3076 is 56 trim ) and also a smaller hotside with 0.6 hotside ( smaller than 0.82 and 0.63 on standard 3076R hence the need for machining )

Figures then must be crank power IMO

Think i paid about £800 ish. advertised at £1200 though.

I'm fairley certain that G-Tech gives wheel horse power as it has no way of knowing transmission loss's, it calculates how quickley you are accelerating a known mass from a standing start. You only have to be a bit out with the weight you input and it can have a huge effect on the power it calculates. To be accurate you really need to take the car to a weigh bridge to get a wet/loaded weight.

probably then,cause 450 whp means more than 500 crank and i dont think it is possible with that turbo.

As g-meter owner, I can say, that you need to be precise on cars weight to show something around truth. Otherwise it can feel that my coupe with k26 has 400whp (lweight of V8 4.2 was left after earlier testing )

I would really love to see the Gtech file, is it possible for you to post it here?
