WHEN John Carson-Wenmoth rescued this BA F6 Typhoon, he and his mates at Maxx Performance in Dandenong got to work. The car had been used and abused; lacking a reverse gear and much oil pressure, the driveline needed love.

Further inspection of the turbo Barra revealed badly scored bearings, leading John to swap in a scrapped FG’s dedicated gas motor and match it with FPV goodies up top. Obviously, this also meant a change of diet, the boys electing to roll on E85.

John threw head studs, valve springs, 1000cc injectors and billet oil pump gears onto the otherwise stock LPG internals, while the whole unit is force-fed by a Garrett Gen II GTX3582 snail.

Dialled to 25psi of boost, the ex-gas Barra now spits out 525kW (704hp), a seriously impressive margin over the F6’s factory 270. To cope with all that extra demand, a surge tank with twin Walbro 525 pumps and an Xtreme ceramic clutch have found their way under the Typhoon.

Prior to beefing up his fuel delivery system, John managed to record a respectable 11.2-second quarter-mile at Calder Park. Now that fuel surge issues have been squared away and John has some practice in wrangling the manual shifter, 10-second passes are well within sight.

This F6 is a testament to the Barra’s capabilities, proof that you can drag a commercial powerplant from a wreck, give it a touch-up, and launch it down the strip with neck-breaking force.
