Well, where is it?

The Dev 5 kit costs $4895.

There is a short block motor available from the U.S, that costs $4235 australian. It produces 254kw and 420Nm. That engine, combined with a new upper and lower intake ($700) and a set of extractors ($500) in an e-series, will do a 13 second pass easily.

It's about the same for either car.

I know bluedriver got himself a unichip for his au xr8 and went from around 150 rwkws to 180 rwks odd ...he swears it goes heaps better too

Mate your forgetting all the labour in the v8 job and the tuning of the above engine combo. Which in turn would add another couple of grand to it again... Plus the E7 heads would be pushing to make that power wouldnt they??? And you'd also need a cam to suit + springs etc etc
Unfortunately the I6 is cheaper to get running up to a point.

But this thread was titled "Where's the power in the windsor?" So lets stay on it.

I'm betting the ECU is raping it through torque reduction. Even after mine has been dyno tuned By Lachlan @ chiptorque and has 3.9's fitted, it still doesnt feel like it has all its guts down low. And Lachlan had said there is a bit of limiting in them.

Thats one possibility anyways...

Stupid question time, how does a short motor produce 250rwkw? Surely it would depend on what heads, intake, ecu, etc, etc, etc you were using.

barry_v

how drivable is the dev 5 compared to this proposed motor i wonder.

the grass is always greener on the other side of the fence fellas. This topic frustrates the hell out of me so I'm not going to post again.

have fun.

I think that even this thread appears out of uncertainty,why dont you all put an effort to come to a situation where you can help each other out to produce good power?

I never believed my AU would ever produce 150rwks!!!!So here is a good starting point and for the price of a unichip and the gains to be had ,it just seems too good to go past .It also suggests that alot of power for you guys is locked away in the state of tune.As I said above Blue driver with an AU xr8 had some impressive gains with Spiro andUnichip here in Sydney..

I gained 13rwkw across the board in my xr8 as well through a chiptorque j3 but the bottom end still sucks even with 3.9's. there is some thing in the ecu that neither unichip or chiptorque can seem to get rid of

Guys these engines have 4" bore and 3" To make serious power they need to REV! To rev they need GOOD induction [I don't mean au inlets either] Unfortunatly the std Ford induction starts runing out of cfm around 4000 rpm.Just where these engines with the bore / stroke ratio start making power..The piston speed with a Windsor at 5000 rpm would be less than a 4 ltr at 4000 rpm due to the longer stroke of the six...
You can't have power to 6000 rpm without losing some tractability down low..
Though forced induction changes that to a point.....
