250 Crossflow Times

[JG3282]

Just wondering what times people have run with N/A 250 cubic inch or 4.1 litre crossflow sixes. Not really interested in 200 cubed or 3.3 litre.

We had a bit of a thing going at a recent dyno comp for opened and unopened.

An XF with headwork, cam, manual, 3.45's etc etc made 102kW at the wheels and a 100% stocko [except for a T5] made 89.8kW which was consistently 10+ more than other unopened competitors.

My XE made 133.1 hp at the bags during a tuning session which is a bees dick shy of the opened XF mentioned above. That XF has run 16.3/83 at the drags, but mine is an auto and has 3.08's. Got a new dunger going in very soon and hope to see what it does, but wanna run the current donk first for a baseline.

So what I'm asking is 250/4.1's times and mph.

Opened meaning any mod that touches oil and Unopened meaning that things like straight gas and extractors are ok.

Just curious
