Is the boost that a car runs measured by peak boost, or boost when maximum power is reached, or final tapered off boost.That's no different to APS saying that their Stage 3 runs 16lb boost, but it actually runs 19.5lb boost peak, then only drops below 17lb at 5000 revs, then 16.5lb a maximum power.It would seem that they want to quote final rather than peak boost. I'm used to using peak boost.Brian Link to comment Share on other sites More sharing options...

It wont make 302Kw at 11 PSI on 98 ron fuel at safe air fuel ratios. Come and prove me wrong, if you believe your right and take my MONEY. Its all good fun.PETERAPS Link to comment Share on other sites More sharing options...

My original statements were regarding the kit that I recieved, which I ran at 11psi boost for said results. Link to comment Share on other sites More sharing options...
Street Tuner Member 727 Member For: 22y 10d Posted 25/01/04 03:05 AM Share Posted 25/01/04 03:05 AM maybe I'm an idiot (no poll needed for that :lol:) but I read it as a 13psi run tailing off ... splitting hairs maybe ... the dyno simply ain't that accurate is it ?? and can this run be replicated over and over or is it a once of ?? Yes, the turbo did produce 13psi for part of the run, but, and its not difficult to read, it had just over 300rwkw @ 11psi. Doesnt matter if it had 350rwkw at 50psi for part of the run, it still had 300rwkw @ 11psi. I didnt claim it was an XYZ kit with a certain amount of boost pressure and power. I said it had 300rwkw @ 11psi....and it does...Anal retention here will prove nothingThe dyno is an accurate power and boost measurement tool. The 300rwkw @ 11psi is plain to see. It should be the graph printed in Zoom for all and sundry to see. The car - and its a manual, ran over 111mph with that boost - wheres the difficulty in understanding this?Sheesh, some of ya just need to get out and race! Like the bloke with the Stage II kit on his T at the drags yesterday (no, it wasnt an APS kit). Had ten million kilowatts at the wheels, like all of them, and got wiped, time after time by my unopened VY One Tonner with 220rwkw. Link to comment Share on other sites More sharing options...

I think when someone comes on here with only PART of a dyno graph and after being asked to produce the rest of that graph for the forum to see ... and then doesn't .... well ... that person maybe shouldn't be talking about anal retentive behaviouranswering a couple of easy questions ... can't hurt ... try it sometime !!

Unopened perhaps, but doesn't every third box of HRT Wheaties (they flog breakfast cereal don't they? The seem to flog everything else) come with a copy of LS1-Edit and a whole bunch of homebrewed super dangerous maps?All Drag racing does (with amateur drivers) is provide referece points for that same driver. Much like dyno'ing in-house on your own Dyno....BTW, what dynos are all the various workshops running? Anyone running something other than a Dyno Demonics unit?A.

Much like dyno'ing in-house on your own Dyno.... Sheesh, 'super dangerous' maps. I can just see Steve Irwin now 'Crikeys, this little timing map BITES!'. Its possible to damage your engine if you have complete control of any management system, which is why its a job best not left to idiots in their backyards. that's why they bring em to me.Drag Racing? Useless really.....unless you want to know the power and acceleration capabilities of a vehicle. Looks like APS and Nizpro disagree with you here as well.Sounds like somone got a can of HSV whoop ass opened on them a few too many times! Dont knock it or get upset brother, accept and understand. Its all about tolerance. Link to comment Share on other sites More sharing options...
aaronmihe Upstanding Member Member 759 Member For: 21y 3m 30d Location: Canberra - ACT Posted 26/01/04 12:09 AM Share Posted 26/01/04 12:09 AM mmmm Martin, So you're saying that I would give and exact equal time driving your ute that say a more accomplished 'drag racer' would? That my level of mechanical sympathy would be the same as yours? I doubt it... As for the maps, you've just highlighted my point, LS1Edit is 'around' and there are some very hokey maps flaoting aroudn for backyarders as well. I wasn't having a go at your actual skills, if I wanted to do that you would know about it, I was simply highlighting that unlike a XR6T which needs a piggyback etc, an owner can tweak the maps on their Gen3 powered car and claim it to be 'stock, and the only way to prove it is to do a comparison of code with a 'real stock' car.I don't street race and I don't drag race so I wouldn't know if I've been whopped by any glorified Commodores.
