lol.. Well maybe it wont be this whole 'the world is going to end and your engine is going to blow up' or 'you're lieing' thing this turned out to be. I gave the exact numbers I got from Dan on the phone. I knew nothing about this 'dyno pack' change. Last time I was there it was dyno jet, so I rightfully assumed that it was still a dyno jet.
I guess this takes the mystery out of it all.. Or maybe someone can find some conversion for dyno pack to dynojet. And we can compare apples to apples, as I thought we were originally
I guess it is what it is..

If both fuels run at least a little rich, timing isn't changed, then fundamentally it should make the same power.
but...
you never know for sure because if one fuel (could be either octane) is closer to stoichiometric it will have a quicker bang. Or the other fuel could be farther away (richer) and the excess fuel cools the intake charge for a bigger bang. which is better, Quicker or Bigger... which gets into combustion chamber shape, crank angle geometry, and other reasons I'll come up with to say that it shouldn't matter but probably does.
If you knew more about the two fuels beyond octane I could make up some more excuses.
PS. BTW, if your still buying, we could get some dyno time in on Tuesday and end all this Kurtis
Let me know, call your boyz.
Find out if we can get some dyno time this week !!
I'll pull the tentioner !! Its probably busted just like yours was, so we might not even need to unscrew it
Jon
And good luck to you GTS ACR. You aren't Black Mamba but you held your own for a short while. Have fun at the track.
they are closed we'll call them tomorrow
ILLSMOQ, do you have the ability to log boost? Perhaps via the SplitSec box?
Why yes, I do have that ability Doug

Jon
what did I miss with Black Mamba? did he finally decide on a blower or turbos???
I got ahold of the dyno guy. we are set for 1:00pm you better get to pulling that tensionor buddy boy...it's either on the car or off the car. I pay if the tensionor off.
Since this is "MY" dyno guy, I'll get the files and of course I'll post the results....even if my pop can has lost some fizz
to test the tesnioners effectiveness, you need to test it on the car and completely off the car. With it merly loose it is still preventing the tensioner from bouncing back an forth.
there is no window. I said I'd be there around 1 with two cars.
so pick one, I buy and you pull the tensioner off or lowest dyno number buys lunch...I didn't even get a chance to sneak my pcm to Dan so I'll be running with the same tune I've had all year.
either way you could be a winner, even thought you're a loos...uh never mind ..!..
1st thats what I am saying. This whole 'test the tentioner's worth thing' is your idea. Since Dan has thrown in a new variable that it was a dynopack vs a dynojet, we will have no 'scientific comparison' to go by. And lord knows we dont need anymore posts by babbling bob about how we didnt have a 'control' test.
So if you want to dyno my car WITH the tensioner on the car, and then take it off and dyno it again, and see what if any power difference there is, then we'd have something concrete to go with.
Otherwise, taking off my tentioner and dynoing does what?
I say Doug FROM DLM should say, "I'll pay for the independent test" right? After all he says his sheet works, why not put money where his mouth is?
If you just want to dyno my car and compare it to yours, cool. If you want me to pay to dyno my car again, thats not going to happen, its a waste of money. If you or anyone else on this forum wants to pay to have it dyno jetted, I'll be there with bells on to give them their data. As far as I am concerned I already have mine.
You pay, I'll play!
Jon
I said if the tensionor comes off completely, I'd pay. Or if you want to leave the tensioner alone and see who pulls the bigger number, looser buys lunch. If you don't feel like dynoing at all let me know. I'd like to let the dyno guy know sooner than later if we are not going to make it.
Since Dan has thrown in a new variable that it was a dynopack vs a dynojet,
I do not think that Dan threw in a new variable. He tends to be a very professional and precise individual. It is far more likely that you made an incorrect assumption and ran with it to your posting detriment. Trying to blame your own error on Dan is inappropriate. He has contributed a great deal to the Viper community.
I guess I should chime in here. The tune was done on our new Dynapack dyno. This dyno is really slick as it allows us to bolt up to the hubs on the car without the wheels on. This eliminates any wheel spin and gives us great load control for tuning. This new dyno reads much higher than our Dynojet. Most likely John's car would be closer to 700rwhp on the Dynojet.
The custom tune we do consists of a boost referenced split second calibration and a custom tune of the factory JTEC engine controller for the best air fuel. There is a lot we can do with the JTEC to improve the tune.
I hope this puts the numbers in perspective,
So Jon, you going to dyno on a dynojet and see if you can truly break the 700rwhp mark?
