The Supercharged Wedges
One model which often slips through the reviewers net is the supercharged SX350. These cars were prepared by the Barrow-in-Furness TVR dealer David Haughin. At the time of writing my information is that approximately 10 cars were modified by Haughin during the 1980`s by the addition of a Sprintex S102 Supercharger, the majority being 350i`s, although some may have had 390 shells, but also a couple of 400`s got the supercharged treatment at that time.The idea was believed to have come from ex drag racer Dennis Priddle. Along with uprated blown power the cars receiveduprated suspension and brakes,Interiors also varied with a couple of cars having SEAC interiors
A non-factory model,
this was a dealer special. At the former TVR dealership "Northern
TVR Centre" in Barrow-in-Furness, Dave Haughins worked with Yeovil
based DPR Forced Induction Systems and took nine 350i wedges and two 400SE's
and added Sprintex supercharger units. Various power and torque outputs
have been quoted over the years, with the best I've found being 260 bhp
at 5100rpm and 294 lbs/ft from only 3000rpm, giving excellant mid range
acceleration. It was claimed that the supercharged unit was a more driveable
engine than the similarly powered 390.
The cost of the conversion
was £3967.50 for the engine work and £1200 for the suspension
package. An uprated clutch was also an option. This would have been on
top of the price of the basic 350 which was £18,015 at the time.
