Powers 4.3

[lawtoni]

A quick cap doff to Dom and team at Powers Performance

Just had a new 4.3 rebuild dyno'd at 407bhp and 374lb/ft at the wheels

which using the 15% rule works out at 468bhp and 430lb/ft at the flywheel

Cats in place, nothing else fancy on the car but with latest MBE ECU

Happy days

I just picked up my 4.3 yesterday. It feels really lumpy at low revs but feels really sweet between 2-3K, possibly fuel mapping issue? Was this the same for you? I’ve only put 125 Miles on it since the rebuild.

It will all be sorted after the running in and after the remap

Until the remap, your engine won't know it's a 4.3 and is doing its best as its former self!

I have now spent a few hundred miles in the 4.3 since the remap and whilst I'm less inclined to get into arguments over the headline figure (which feels about right from the car's performance IMO), I can reveal that it is fantastic!

Relentlessly fast! Possibly too fast for the public road. The acceleration does not seem to let up at all.

5th gear pulls like 3 gear did in the 3.6.
I've just ordered 4 new tyres to replace the 5 year old rubber that was on there before which I expect will help a great deal in taming the car.

So 470whp, 400whp or 100whp. It is marvellously quick!
