Turbocharging a VT V6 Auto

[Cubes]

Its all about gearing.. Look how much quicker an Auto Commodore is quicker off the line than a Auto Falcon.

The EF,EL,AU Falcon has 357Nm of torque compared to the VX's 305Nm.

The Commodore kicks the Falcon's arse its as simple as that. BUT mate a 5 speed in the Commodore and a 5 speed in the Falcon and watch the Falcon come to life.

so true, i just drove a new ba falcon hire car while in cairns and damn the gear ratios r so ***in long, 1st will take u to about 80km/h and second to around 140km/h

Why would the US be spending more $$ on R&D compared to the Japs?

The GenIII was designed basically as a truck engine, that would still be able to see duty in GMs premiere sports car the Corvette. Truck owners want cheap, simple, reliable and durable engines, that meant a single cam and pushrods. Several hundred thousand of these engines are built every year for trucks.

Now for the Corvette, they appreciated it was tough to beat quad cam 32 valves for outright performance. But had to make do with a design that had to firstly service the cast iron light truck engine.

This meant a lot of work going into 2-valve cylinder head, roller rocker, materials etc etc design.

Designing an engine to be flexible enough to fill several roles meant development costs could be spread over a much larger spread of engine sales.

Your right im only guessing and dont have the facts at hand, but the Japs continue to use engines that by way of their mechanical design are more effecient.

The cost of getting something to perform better than it has any right to costs a lot of money. GM started with a huge handicap when designing the LS1 as it had to retain pushrods to cater for the truck market.

I imagine Nissan with the RB had a blank canvas when it started work on this RB series of engine. It was to be a passenger car engine, and when time came to spawn a performance derivative, they were able to simpy refine a sound format, not a previously compromised format.

Just need to find out how to fit a blower without loosing the AC or putting a massive hump in the bonnet? Would definately be the ultimate combination.
