BLOWN AWAY

HORSEPOWER HEROES

STORY IAIN KELLY

ADAM Rogash and the boys from MPW Performance were back to oversee an action-packed Horsepower Heroes dyno comp at Summernats 31. Once again a yellow Torana sedan prepared by Jake’s Performance took the overall win, but this time it wasn’t Jake Edwards’s own turbo big-block Chev-powered example, but Paul Allen’s Roots-blown car – the first time in the event’s history a traditional blower-equipped car has won the big prize!

Paul, Jake and good mate John Whyte whipped the single four-barrel carb and manifold off the 572-cube big-block Chev in Paul’s yellow LX sedan, replacing it with a 14/71 from The Blower Shop and mechanical methanol injection. It had made 560hp aspirated, but almost doubled that figure on Saturday at Summernats with 1036hp to qualify for Sunday’s finals. Then it pulled 1019hp to take the win, despite struggling with AFRs.

Paul beat out Greg South for the Horsepower Hero title, even though Greg’s twin-turbo LS HQ Kingswood top-qualified with 1081hp on Friday. While Greg loaded some more boost into his Haltech ECU for the Sunday final, a torched lead dropped the LS onto seven cylinders for a top run of 915hp.

The laptops were out and boost wars were in full flight in the Forced Induction sixpot class, with Shaun Cole’s eight-second RB30ET VL Commodore and the Barrapowered nine-second Cresta from Mighty Car Mods duking it out. Ben ‘Mechanical Stig’ Neal helped build the Cresta, which packs a stock-bottom-end Barra, GTW38 Garrett turbo and plenty of Haltech engine management. Running on E85, Benny squeezed 692hp on 23psi in qualifying and then topped out at 689hp on Sunday.

While super-stout, it wasn’t enough to stop Shaun taking back-to-back wins in the class. His VL backed up its 690hp qualifying run with an epic 720hp on Sunday, running over 50psi through a Garrett GTX42 and sniffing E85. The three-litre Nissan six also sports a billet crank after Shaun discovered a V-crack in the old one following his win at Summernats 30 Horsepower Heroes.

For the aspirated V8 fans there was a beaut Ford vs Holden battle between Luke Hannigan’s 427-cube XB coupe, which threw down 510hp, and Daryl Elliott’s LH Torana sedan. Luke had been superconsistent, with his big-inch Clevor rolling 510hp through several trips to the MPW dyno over the weekend. However, it was Daryl’s screaming 434ci small-block Chev that thumped out a winning 551hp.

The Four-Cylinder Forced Induction class saw Scott Forrester’s ARROW Gemini come back to the dyno, despite having hurt the Isuzu turbo four-banger at Drag Challenge this year. It made a smoky 709hp in qualifying, before belting out a monstrous 839hp on Sunday to take the win, though it looks like that run seriously knocked the donk around. Runner-up Michael Brucic’s S14 Nissan 200SX put in a huge effort, with 40psi being rammed by a Precision 6767 turbo into the forged 2.0-litre to stomp out 716hp. With its SR20VE variable-valve-timing cylinder head, the SR20DET absolutely screamed in the cell. s
