BLOWN AWAY

STO RY IAIN KELLY

THE dyno hall was packed solid for Summernats 30, with dozens of punters through the door to see what power their car makes. Adam Rogash and the MPW Performance boys were running the Horsepower Heroes show this year and, while they only had one dynamometer compared to the previous year’s twin set-up, they got through heaps of cars.

While we saw strong results from turbo fours and sixes, everyone was hanging out for the top-dog forced-induction V8 class, which saw a familiar face back in the hall. 2008 Horsepower Hero Craig Munro brought back his legendary twin-turbo TRYHRD HSV VX ClubSport to have a tilt at knocking off Jake Edwards and his 2000hp LH Torana. But it didn’t all go to plan.

With a new twin-turbo LS combo in the car, Craig was looking to go deep into the four-figure power zone, but a leaking blow-off valve held him to 15psi boost instead of his normal 40psi. This meant he only ran a best of 798hp, a long way short of the car’s 1800hp potential.

Jake Edwards pushed his Merlin up to a 4.5-inch bore, taking the big-block to 477ci and dropping compression slightly, but with the same cast heads and 110mm turbo from 2016. With only 30psi, he made 1461hp to qualify in the lead.

Then the drama started, with both Craig and Jake wanting to run last for Sunday’s finals. In the interests of fairness, the MPW Performance crew chose to put the three finalists’ entrant numbers onto slips of paper and had random spectators draw them out of a hat to set the running order. This put third-placed Greg South up first in his twin-turbo 427ci LSX HQ sedan, followed by Craig and then Jake.

Apparently unhappy with having to run second, Craig drove out of the hall, but returned in his car 15 minutes later and parked the HSV with bags of ice on the engine. But he then left the dyno and nobody could find him as his timeslot approached. After waiting 10 minutes for Craig to come back, the dyno crew disqualified him, with the crowd counting down the last 10 seconds.

They cheered loudly as the time ran out and Jake fired up the Torana, whipping off 1593hp at 34psi and then 1663hp at 40psi to take his fifth win at Summernats Horsepower Heroes.

“I wasn’t going to run it, as I’m working on putting this engine into a tube-frame drag car,” Jake said. “But I was cajoled into bringing it back, and I’m glad I did.”
