Xflow-4AGE 20v swap complete
As per title, I have swapped my modded Xflow for a 4AGE 20v, the conversion took around 5 months, had the car set up on a rolling road yesterday and
had the first real drive, power run results were 99kw and 146 nM at the wheels....bog standard engine(more to come?)
The first drive was a revalation, way smoother than the Xflow and the power is awesome, the fact that this thing revs to 8500 without a fuss is mind
blowing, I hate to say it but it blows the doors off the Xflow without breaking a sweat!
Should have done it ages ago.....
Cheers

Just about the same height as the Xflow, although I have a chopped sump, the oil filler clears the boonnet by about 2mm

Glad you're seeing the benefits of this bomb of an engine.
Have you got any photos of your sump modification? - I'm interested in doing the same....

Ham,
Silvertop or Blacktop? Your power figures on that dyno are very similar to the dyno I use and indeed OMEX and RAW use a lot. If you've got a
Silvertop then the Blacktop is actually even smoother and power peaks 400RPM higher than the earlier Silvertop. If you're reving to 8500RPM and
till making power then it sounds like you're using a Blacktop.
To get the best from these engines you advance the cam early (VVT on the inlet cam) in the rev range then retard the cam again at around 7000RM to
gain a little more top end. Seems to benefit the Blacktops more though.
The pic below is how I shortened my sump and gained a little capacity. This doesn't show the baffles very clearly though.

Running a silvertop with a gotech Mfi ECU, my vvt kicks in at 2100 rpm and is de activated at 6800rpm, its revving to 8500, but peak power comes in at
7800 rpm, only point in going past that is to ensure I am in the band for the next gear!
Your sump looks very similar to mine, I have hinged flaps on the sump "wings" to conteract lateral oils surge in the sump as well
Cheers

Thinking out loud, I wonder if i could use a key safe as the sump add on. it would look pretty and save on some of the welding.....
