I dont like slandering people but i will never have another car on a Chassis Dyno or a Engine Dyno without me present.

Did you check your front spoiler? I'm surprised that the chocks didn't flip over backwards like in a failure and put pressure on the front air dam.
No dramas there Pat, the chocks weren't overly large.... I did notice that, but the spoiler is no grader, thats for sure...

let me know if you need a tail light, I think I have a black ine here somewhere
Thanks for the offer makka, two black SS style taillights now reside in the Hatch (picked 'em up for $15 pair at Calder swap meet yonks ago!)
Liam, I'm still winded by the kick in the guts!

I was under the impression that Lakeside was the two guys who originally started Gas Research!i would take the hatch to gas research in dandy south
But I suppose I could call GRA and see if they reckon they could get some more out of her...
Thanx for the heads up on the tickets mate.
Might have to see you about your exhaust guru!!!

Yeah..... can anyone shed some light on why she'd do this. I don't have enough knowledge here...Mate idling at 1200 in park then 600 in gear ... theres a problem there thats just wrong
Thanks for the replies people.

so what id be doing if i was you is saving for a motor transplant.Can i also say every time ive had my cars dynod in sydney i always get them to strap down car ive seen what can happen i saw a hz wagon blow a tyre an jump of dyno at about 100ks it was not a preety site no one was killed but it left a dirty hole in the wall an car was totaled MORAL even if your car has only 50kw shit can still happen it takes 5 min to put a strap on there just bgucking lazy if there not doing it all you gotta do is tell em no straps no dyno its easy.

Maybe I was lucky. But my advice is work with the problems you have, rather than turfing it and importing a whole new box of unknown problems. Don't throw out the baby with the bath water.

From my experience a 253 making 83kW on LPG is more than acceptable.
As a comparison a VS or VT 5L auto goes 95-100kW, a good 308 with 286 Crane, extractors etc might go 145kW, a stock 202 goes 45kW.
Don't get too hung up on the numbers, if you want to know how much power the thing has then shift some weight down the quarter.
FWIW Who here would tie their car down when checking the timing in Park? And I guarantee the car was not actually in the rollers when this happened (the rear roller freewheels - only the front roller is loaded - you cannot get out in reverse - you must drive forward to clear the rollers, then back out over them again.)
Strapping cars into the rollers has more to do with controlling wheelspin than safety, if the car wants to climb the rollers it is probably being tested at the wrong acceleration rate.
Cars ARE usually run in a lower than 1:1 gear because of the roller speed.
Like I said, I hope this clears up some misconceptions.

Hanging around at my engine builders from time to time,
I've seen 253's making around 80 rwkw mark, VN 5lauto 102rwkw
307 chev [mildly worked] 128rwkw, vk injected 202 78rwkw,vz alloytec
125rwkw, hz 308[mild lumpy] 120rwkw ,and many more, also witnessed
a few hugely powerful cars of all descriptions. My point is, it's surprizing to
some people to find out the actual power figure, at the treads.
my worked 202 at 114rwkw[152.2rwhp] is in pretty good company,
i think anyway!

Yeah, a standard 202 is lucky to push 101 RWHP, and that would be on a good day, and a bit further down the track from Standard.

I agree take it down the qtr and see how quick it really is....
Im keen to see wat my engine would make now, i would be pretty happy with anything over 120 by the sound of it...
Cheers guys

Still.... 45kw out of a stock 202? I think the UC's in for some attention!
Anyone know what the dramas are for a V8 in a UC? Engineered of course! Chassis strengthened?

Also agree, quarter mile is a much better indicator, where you get the combined effects of torque and HP, must be why the ricers stick to the dyno and not the quarter.

The more and more i look at it i start realising that the Qtr mile is the only way of really tellin how tuff a car is.... and if you want to go further the Track is the only way to test the whole car.... The Dyno seems only good to tune the car to its optimum...

Keep pushing, your 253 has the potential to make more....
