Who has experience with these types of load bearing dynos? I do not see anyone really using these for fwd cars.

 

Talk to Chris@Xenocron

 

I think MASE at stage 6 uses one too.

They are very sweet dynos. It was just out of my price range for now.

 

Im not a big numbers guy, I know the numbers will read low compaired to say a mustang or dyno jet. Was wondering if anyone else mainly used one instead of a braging numbers dyno. We use to use a dyno jet and seem to get a much much better tune on the DD.

 

all we will tune on is a load base dyno never used a DD but have used mustang dyno and land and sea. i did get a chance to drive on a DD at seama last year it is a nice dyno for the price.

 

chris at xenocron has a dyno dynamics and it is a very nice machine, as another user posted they are great for the money, i was under the impression that they did tend to read a bit higher than most dynos, such as the dynojet and dynapacks. but whatever it is it still works and get you numbers!

 

i was under the impression that the dyno dynamics was a heart breaker compared to a dyno jet due to the lower numbers.

 

who cares about numbers if its a better product and makes the cars easier to tune and gives you a chance to do a better job of it

 

No its the other way around, its a load bearing dyno, some were around 15-20% lower people have seen.

 

Yea, usually mustang and dyno dynamics read lower.

 

If let's say you dyno at 600 hp to the wheels on a mustang dyno, what would be the approximate hp on let's say a "dynojet"?

 

It really depends on the ramp rate used for the pull. The first time I was on one I thought the car I was tuning was broken Nice to tune on though.

 

Its all based on percentage. All of the dyno's read slightly different. Some of the dyno dynamics owners have re-adjusted their dyno's readout to be similar to a dynojet to keep customers happy and have a decent reference for whp. I own a DD myself and i can no longer see myself tuning a car on any other dyno.

 

You can make a Dyno Dynamics read about any way you want, you can change the correction factor with a simple couple keystrokes. Control-X and pop in a new correction factor on the Dyno Dynamics dyno... bam... done you have better numbers. Also if you dont have the ramp rate, weather data, etc all correct you will affect the numbers according. Generally though a properly setup DD I have been told and seen will read much like a mustang dyno.

Dyno's are just tools and useful for measuring results agianst themselves given the operators are not attempting to make a dyno read a certain way or using any tricks to affect numbers (which can be easy or harder to do based on the brand dyno, the model, software, etc).

 

I could never make cars (FWD) hook anything over 480whp. I hate the fact that you cant drive the car off after its sitting in the rollers. What a PITA that is.

 

Mustangs are all over the place. I know a shop that will baseline your car low and then change the wheel weights for your end result. You leave happy every time LOL

Dyno Dynamics makes a nice product. You can roll that sucker right out of the way when you aren't using it with ease.

 

That is you. I have made well over 480whp on a DD and had no problem. I have never had a problem driving the cars off the dyno.

DD are different then most dynos. If you do not know the dyno, you will hate it, but when you get use to it, it is hard to go back to other dynos :p

 

if you want a good tune then DD is the way to go. if i had a DD and a dynojet side by side you better believe id jump on the DD.

on a side note though if you think about it dyno dynamics is the better choice either way..if youre looking for a number you can change it easy and bam you have your dyno queen!...nobody would ever know anyway because it will just sit there anyway and then theres guys like me who the only numbers i give a crap about are e.t. and mph.

 

btw a DD has a brake for the rollers why wouldnt you be able to get off it

 

as long as it works as a tuning tool to the best of its ability then who cares about the # most of the time we dont use the corection when we are tuning the dyno is just a tool. i cant tell you how many times we have had cars run faster numbers on the track with lower # then another car.

 

The brake only work on ONE drum. The other drum free wheels as you try to drive the car on and off.

I'll stick with a Mustang dyno.

 

It is... I made 222 on an allmotor B-Series on a DD . . . how much is it on a dynojet ?

 

I don't really understand this statement. I've been off and on DD's with both AWD and FWD. We always drive it on....and drive it off. Only thing we have to watch for is the lowered cars.

Let's see (preface this as dyno's are tools for tuning. Number comparison is just kinda a fun offshoot that can be manipulated), Been tuning my cars with a DD for the last 3 (?) years. My tuner (Matt K from Dentsport in Norwood Mass - I believe he's on here) swears by it. Yes, it is considered the "hearbreaker" dyno that will read low. But he seems to love its mid range load tuning ability (I don't want to speak too much for him. I'll let him do that if he sees this). But he tunes everything from Ferraris to Honda's to Volvo's on that thing. Says he loves it. FWD, RWD, AWD.

Now, with that being said, I have taken my car (tuned) from the Dyno Dynamics directly down to a dynajet (I'm curious like that) on three separate occasions and came up with exactly (or within tenths of a whp) the same number as the DD . The Dyna was set on ASE correction factor.

The numbers were in low whp (Eclipse in the range of 200whp) and they were NA numbers (no turbo obviously). I found this curious and after discussing this with others, they were saying it had to do with turbo numbers. So when Matt did my second runs with the 420a turbo'd Eclipse (around 440whp), I decided to head down to the Dyna and see what we got. Well, unfortunately (as happens on dyno's) it didn't go as planned. My first run, I threw a alternator belt. That made it break up as it was going into the 5.5k range and we didn't get a clean pull in. Funny thing though, was that I ended up with the same number as I got from Matt with our previous DD runs. So obviously, a clean run would have netted me a higher number.

Just points of curiousity. But yeah, the tuners I talk to seem to like the DD over the Dyna BUT they also want to please their customers who want the higher numbers, lol.

I think most people's REAL dyno on here is the track I agree with a lot of statements on here. When I was building and playing with my car, we barely cared to dyno it much. I think I put down a total of ~ 10 dyno pulls with my car before we unstrapped her and waited for the snow to melt and go racing.

 

In the end the only numbers that matter are the ones posted on the big scoreboard at the strip.

The dyno should be used to get your car sorted out so your ready to get to the track.

But you'll never stop the keyboard drag racers and dyno racers so you'll have to learn to live with it..
