    Got told by someone once, rule of thumb is flywheel kW = rear wheel horsepower.  I am guessing it’s going to make say 350kW at the flywheel, so that equates to approx 350 rwHP.

    So there’s good news and bad news. The good news is that the car is running perfectly on the dyno up to 4 grand, everything is spot on, oil pressure, temp, no funny noises. Bad news is that it’s running out of fuel when it revs over 4 grand. Seems to be a fuel supply issue, either there is a pinch in the fuel line somewhere, the pump intake is partially blocked, or I have mounted the pump too far down on the hanger and it’s too close to the bottom of the tank. The tuner is going to pull the pump out and have a look. The saga continues.

    It’s all part of the fun. Hopefully it’s something simple like the fuel pump hanging too low. If it’s a linked line you will most likely see that

    Yea I agree with Cav, actually for “bad” news thats probably good if that makes sense.  Prob something quite simple.

    Thanks guys, yeah i’m hoping its something simple. Keen to get it back and start putting it back together. Spent the weekend working on the bonnet, more sanding and primer, sanding and primer, sanding and primer. Feel like I’m polishing a turd, but it’s slowly getting better. Definitely will be on the hunt for a new bonnet next year.

    Finally all done. The fuel issue was the hose on the hanger that runs from the pump to the hardline on the hanger, it was leaking, the hose had started to deteriorate for some reason. The hose was replaced and it was all good. Ended up making 320rwhp, lower than I thought but the tuner said the high stall and TH400 suck more power out of them, said it’s making up around the 450 mark at the fly. A/F ratio was dead flat, it’s running perfectly. Everything else is fine, they went over the whole car and mechanically it’s ready to hit the road. Now I need to find some extra cash to pay for the extra work the had to do haha

    320rwhp, by my rule of thumb calc means 320 fwkw, which is 430fwhp which is around what they are saying.  Imo peak HP is such an overstated number, its a pub pissing contest.  It’s all about the shape of the power curve to produce it on a streetcar.  Peaky engines are a bitch on the street.  It will spend most of its life around 3,000 rpm, when you boot it at that, thats when you want it to stand up.  It will boogie mate, no doubt about that.  Top work.

    Stock they are rated at 430hp. With tune and a few bolt ons it should be around 450ish.

    Some will say your figure is low, but thru a stalled t400 and a 9inch it’s about right. If it had a t56 or t6060 it would be closer to 300kw

    Hahaha yeah true mate.

    There’s a dyno video up on Facebook. Search for DC Tuning & Mechanical, they’re based at Wyong on the Central Coast. They just put the dyno vid up.

    Cheers mate, yep it’s got a nice note to it.

    Finally had a great weekend with the VK. Picked it up saturday morning, chatted to the tuner who said everything is perfect. Ran great on the dyno, A/F was dead flat all the way hovering on 12.5, motor pulled all the way to 6400. Unloaded it from the trailer and went for a little squirt up the road, it’s heaps toey down low, torque is awesome, has a nice quiet note at idle but opens up when you give it a bit. Also did a small skid in the garage haha.

    Dyno sheet reads 239.9rwkw and 1261NM.

    Started on the bodywork on Saturday and continued yesterday. Wet sanded the roof, C pillars, both rear guards and the boot. All the marks and crap that was on it are gone, all the peel from painting it in the garage at home in winter is gone and it’s silky smooth ready for buffing. Next is the doors and front guards, bolt the guards on, check over the bumpers and probably give them another few coats of clear before they go on.
