Mark McGuckin tells the story of how Trespasser was built:

"Myself and Keith Scott (drinking buddy) started the car back in 80/81ish after getting sick of going to York raceway and just spectating. The original chassis formally had a motorcycle engine in it and no cage. The cage is made from the finest cr/moly tube which we…” (edited to protect the guilty) “...It is of the type used in nuclear power stations. If my recollection is correct the rear end is from a Morris Oxford picked up from a scrappy for about £10. We shortened it ourselves and got a welding buddy to stick it back together.


The right half shaft give out on a hard launch one time (pretty scary). Keith was the engine man and I did the drawing up and the driving. The car used to run very consistent 12.4 / 12.6’s getting very close to dial in every time. It was great taking out a 6 lt yank on the start line (which is where it had the advantage), but max top end was only 105 (scary enough in a metal tubed go-kart) so the yanks were catching up quickly usually 120 terminal. The spec then was 2.1 ltr. New pistons & race cam. No rad just filled it with water and went. Could not stay on the line too long or it boiled over.
I remember one time Keith thought he might show off in his drive way. Loads of revs in first. Foot slips off the clutch. And he is doing 30 mph before the back of the garage come up.* We had to rebuild the front end from the engine mounts. We took this chance to make the car a bit longer and it worked a treat and we never looked back." * The start of the demonic possession perhaps?.
