who cares a dyno is just a tuning tool!!!

 

The dyno Blackbird is talking about is mine. I have the 4000 model Dynapack and when I first bought it I had a loaner computer and brain. When we first started running those cars, they seemed to be pretty high, but at the same time, some of the cars where going what they said they should from the HP given at my dyno. So I took it as a grain of salt, then I got my new computer and now all the cars are back down to somewhat a more closer HP number to other mustang and dynojet dynos. I dont realy care too much about that, but it was sometimes hard to explain what was going on and sometimes people dont believe your hp numbers. But it was more about the before and after difference that I was going after. The only thing I havent had a chance to do yet is put one of my previous cars back on it and run some pulls to see if its the same or less. So I think what blackbird was asking was if you had the same problem I had.


And to answer anyones doubts about the dynapack, there is no way I would ever touch another dyno out there after using this one. I have used them all. You can see things you cant see with a set of tires on the car. At 85K, it was a worth while investment. No tire slip and the best part is the true ability to tune a car. EFI has tables, and if you cant tune them, then you might as well put a carb on the car and go back to using a Dynojet. I have cars around my area that wont let me tune their cars because their only reason is I have to take their wheels off and my dyno is unsafe. Thats like saying the world is flat.

I will however have one of our 700hp dynojet cars comming back for more tuning and I can do an honest comparison if it matters to some folks. That way we can see what tire spin and non tire spin does for numbers if anyone wants to know. Hope all this helps.

I agree all the way. Thats why I laugh at all these cam guys that make these Dynojet friendly cams like the T-rex and other big *** cams. Then you put them on a dynapack like mine and they make no more power than your tr224 or other smaller cams. Its an eye opener.

Rick

 

I would like to hear more about this statement.

 

I say this because most people dont need big cams like that, and the problem around here is that everyone says go with the biggest cam or what ever the next craze is because some dude made 600 cam only. Well, guess what happens when you put cams like that on a loaded dyno? You really see what a crappy TQ curve they have. You dont need to over do your cam to go 10's, look at the Cartek guys. All their cams are in a decent size range. Aren't they some of the fastest cars around here? I see the same thing myself. I had a MS3 cammed car on my dyno the other day and after tuning it made 392hp and 382TQ cam only, no heads. So tell me how was that any different than half the other cams I have done much smaller and made either the same or more HP. Plus there were parts of the TQ curve that no matter what you do in tuning, you cant raise up certain areas in the curve.

Now here is why you see big numbers, all these guys use a dynojet. Its an accelorometer. (sp). How you effect its rate of acceleration rate is how you affect the numbers. It doesnt even read TQ. TQ is what needs to be read, thats how you get HP, not the other way around. Have you ever noticed that every dynojet graph looks the same? Well, no one cam is the same, so why should the graphs be. This is why I dont see what all the hype is.

Of course I have people who dont follow this and tell me they run 10's with their big cam, and I tell them, their are guys with smaller cams doing it too.

Thanks for the explanation on this it clears things up and makes sence to me. I will stick with my baby cam as well because it does just fine only wished it sounded a little meaner.

 

Looking at the cam you have in your sig, thats a great cam, and all you will need. That cam will have a great power band, and good TQ curve. Plus its on an XE-R lobe too. Even better. And remember, dont judge a car by sound, wont get you anywhere.

Rick

 

Meaner!!!???? WTF! Your car already screams like a Nascar when you hit it. How much "meaner" are you thinking? Learjet? Space-shuttle? Super Nova?


Also, thanks Rick for taking your time with Lou; great info for both of us on cams....

 

Super Nova would be kinda cool.

If I drove it as a daily driver I would be asking how to tame it down some I guess you know me I am never happy.

Forgot to mention thanks again Rick for taking the time with me on the phone today with all my questions.

 

here are the dyno sheets

 

here is the boost graph

 

what the heck was going on with the dyno graph. A dynapack shouldnt have a graph looking like that. Did you finish before the run ended? Did someone let off then get back on again? The graph seems to be all over the place.

Rick

 

sorry about that try this boost graph see if you can read this

 

they said that is where the tourqe converter locked.

 

Weird, I always run my convertors locked and I have a model 4000 also. I never had any runs look like that. But all in all, Awsome freaking power. Good job with that D1sc.

Rick

 

My car on the dyno did the same thing on DP setup.

awsome power rob got out of it. I have personly seen the car at the track and the dyno graph. Everyhting he said about the is true, seen it and verified .

Harry

 

Who did the tuning on the car? Does it have the stock PCM or does it have an aftermarket setup? Nice numbers

 

Ken from HPTuners did the tuning with Rob "consulting". :p

I can vouch for the car as well, I've seen it at his shop a couple of times and went with it to the dyno that day (where my car holds the record for 'parts thrown furthest from the car on the dyno' ! Plastic ATI plenum exploded and flew across the shop.)

Not that my 2 cents ever mattered, Regardless of reliability, he did say he was running 10.2 CR. I made 822RWHP on a dynojet on pump gas, with less than 15psi on 10.1 CR. I did have more CI and more stroke. BUt with 15 PSI and that intake he is using is different in design. I dont want to say it is or is not feasible, but he is in the ballpark of what I did.

 

This brings up a very valid question. Who is to say that Mustang, Dynojet, Dynopak or any other dyno is right? Maybe on this forum we need to pick the dyno in which all will be measured and that is what we will all go by.
