Power and torque curves, preferably on a dyno that isn't tweaked to show customer pleasing big American ponypower Specially with the single turbo because my VG30DET was on the dyno the other day.
Do you have an issue or problem with American individuals persay? or is it something else? Just wondering is all.
Honestly bud I haven't the slightest clue. I haven't seen his manifold setup or anything. I'll ask him to send me pics of what he has so far so that I can post up but I'll be waiting just like everyone else.
You can bitch and winge all day about US dynos but 400m is the same anywhere in the world and they pretty much kill us with the times they run.
Not at all, nothing personal, in fact I've posted on one US based forum for years. What does get me is the amount of US rubbish HP figures around on forums. One very experienced US operator told me that it is common in the US for tuners to fudge HP figures just to keep customers happy. And a dyno operator here has shown me how easy it is to do that. So are we clear now where I'm coming from?
It seems much more prevalent in the US than anywhere else going on my experience over a long time with certain engines that I'm familiar with. And then people believe the nonsense and think that US engines are generally more powerful than anyone elses. No wonder if AU tuners are starting to fiddle their outputs too. Anyway, I was mainly on about power and torque dyno sheets and how both outputs are relevent, more so with real world street and circuit race cars. Drag cars? Not interested and would not have a clue.
Drag times and also mph is the real test, even this can be false, some magazines even quote estimated. A time slip is proof. Different dyno's read different, most dyno's in USA use in ground single roller. Then there are hub dyno's which have less frictional loss, software corrects this but? Plenty of cars in Australia and I am sure in USA have a sizable in balance from rear wheel kilowatt reading to ET at the drags and more importantly a relatively slow mph.
Drag times have to be an appoximate measure of horsepower at best, given all the variables. Anyway, as I said before, drag engines bear little relevance to street or circuit car engines where torque and power bands are important. Which is why I keep asking for them. On the US scene, part of the problem could well be their dynos because the few Dyno Dynamics sheets from the US I have seen look pretty realistic by AU standards. But I do get pissed off by the common US attitude that in effect denies that there is a problem.
