Thread: D3/D4 Power Upgrades up to 300hp on the tyres

What engines and at what reliability?

I'm looking forward to seeing what you can do, especially if you do the 2.7l TDV6 also, not just the 3.0l like everyone else.

I've also moved this thread to here, you should get more responses here.

Baz.

Interesting, more info on torque figures rather than HP please...

300hp is approximately 20% over a std HP 3.0L

Not an unexpected gain.

More interested in the 2.7l upgrades.

I know that HP sounds better but can we talk in KWs and NMs.

Cheers

Garry

300hp = ~224Kw at the wheels

are the standard figures of 180Kw measured at the flywheel?

Roo Systems dyno showed the starting number of their D4 @177hp = ~132Kw:

So, MitchellBros are getting 69% improvement? Have I got that right?

If that's the case then, bloody hell, that thing would go!

Aaron, got any pics or footage of the test?

EDIT: assuming this is a 3.0Ltr - was the upgrade done on a V8?

So far we've been able to achieve up to 300hp with an exhaust upgrade and ecu re flash. All safety parameters in place, including torque limiters.

Your thoughts are appreciated.

Very interesting. As other have asked will this be for the 2.7's? or just the 3.0?

Not sure about the 3.0l. But the 2.7 already had enough of their share of tc lockup problems... Only to put more stress on it?
