TURBO V8 CHRYSLER CENTURA - READER'S CAR OF THE WEEK

JASON MUSU'S V8 CHRYSLER CENTURA

WE RAN into Jason Musu at the Street Outlaws finals at Calder Park on Melbourne Cup Day. Anyone racing with horsepower as opposed to, er, horse power gets our tick of approval, and even more so when they’re running 10s in a boosted V8-powered Chrysler Centura streeter!

I’ve had this car for 20 years, and it’s been my only project car in that time. It was in pretty good condition when I got it – a daily-driven factory manual 245 that ran on LPG.

Mechanically it was great, it really only needed a paint, which I did around 18 years ago. I reckon the blue has held up pretty well over the years!

It now has a 318-cube Chrysler V8 that has been completely overhauled over the 20-odd years. It has a cast crank, H-beam rods, forged pistons, custom-grind cam, and a bunch of other goodies. It’s boosted by a GT47 turbo running 19psi, making it good for about 600rwhp on 98-octane pump fuel. It can go all the way up to 30psi on pump fuel. It runs through a 727 three-speed transmission.

Jason -musu -chrysler -centura -2Do much spannering yourself?

I do all of it! Pretty much everything that doesn’t involve machining I have done myself. I built the engine and did all the fabricating for the turbo set-up. I’m a self-taught mechanic and I’ve been playing with cars since I was about 16 years old; I’m 45 now! It’s like anything; if you’re passionate about it you’ll excel and I just really enjoy working on the car. I’m also a Mopar man so I wasn’t going to put an LS in it, but that also meant having to do all the research and development work myself. So much time and effort has gone into figuring everything out, but I wouldn’t do it any other way.

Jason -musu -chrysler -centura -5How fast has she gone?

My PB for the car is a 10.00, but that was with a poor 60ft. I need to put a transbrake in the car and then it’ll definitely go at least a 9.60 I reckon. I’ve already got the ’cage in it; I just need new gears - it’s got 2.92 gears at the moment - and a re-tune. Once I get the transbrake sorted I’ll increase the boost and see what it can do.
