Supercharged Crossflow - 252bhp !

[Moto]

I stumbled across this Westfield on the WSCC Northants site.

"These pictures are of Horace Marks' early SeiW which started it's life with a "standard" 135bhp 1700cc X/Flow and after numerous changes and engine rebuilds the original block and head is now fitted with an M60 Eaton supercharger sucking through a 2" SU carb. and blowing at a pressure of 10lbsf. It has forged Omega pistons and on a rolling road session last year recorded 252bhp @ 5100rpm and 280ftlbs of torque @ 2800rpm. It has since been slightly detuned with a thicker de-compression plate. It has Toyo R888 tyres and has been surprisingly reliable since the fitting of the 2" carb."



I'm sure it'd be a challenge to fit into a Vixen but would this be a nice way to get Tuscan V8 power and torque without the V8 weight and therefore losing the Vixen's balance, whilst retaining original / period engine?

You can never get a 4 to develop the torque of an 8!!

Nice example of oldskool tuning though!!

Not too sure if that inlet arrangement would fit in particularly as its low but would be interesting to get the measurement to see!

Ford engineers supercharged crossflows on a few applications.. Also google Lumo 105T which was another little crossflow mod of the period…
These days Turbocharging is a lot easier.

There is a wonderful Vixen with a turbocharged crossflow in Surrey, I don't Gary comes on here. We featured the car in Sprint in early 2010, I am pretty sure that he has had it dyno'd at well over 252bhp.
