Hey guys,

New S2k owner here, just picked up my 05 Sebring Silver S2000 last week. I'm planning to do some mods in the future but for now I'm leaving it stock as I only have 400 miles on it. Right now I'm in the information gathering stage. I've searched the forum and found info on intakes, headers, exhaust, and tunning. From this I've made my parts list and have a local tuner set up to do the wrenching. What I haven't been able to find is any info on the different types of dynos. I've seen posts with people using Mustang Dynos, Dynojet and DynoPack. My question is which one gives the most accurate numbers??? The tuner I'm using has a DynoPack dynometer which until now I've never really heard of.


Any comments or advice will be appreciated.

Thanks!!!

 

As long as you stick to using the same dyno, the numbers should be comparable. Comparing numbers across dynos is guesstimation as best.

There is no one objectively better dyno. Some are supposed to simulate driving conditions better to more accurately judge how much power you have in a real world sitution...some don't. The best dyno is an engine dyno!

DynoPacks should be fine for tuning and getting numbers. I want to think they read a bit higher than the roller dynos, but it's been a while since I've looked into dyno information.

 

I don't think which dyno you use that is so important.. as long as you use the same dyno and tested the same way each time for comparison.

 

just remember, as i said in a previous article. roller dynos are cool. lots of neat sounds, and make up about 60% of the dynos you will run into. the problem they present is they take up mad room. and they show you exactly what you are putting to the contact patch. problem is, as i stated, too many factors can fudge your numbers. tire pressure,wheel diameter and weight,excess tie down pressure, and what gear you start from and how rough you are on the throttle (this has to do with wheel flyweight).
now if you are running on a dynapack. you have one cool repeatable aspect. the wheels are removed. so now ALL the stuff i just mentioned is gone. you will show what i would call correct numbers. what your car is putting mechanically to the hubs. many say *you dont race with the wheels off* duh, i know this. but the thing is YOU know, if you slap on a light ass set of 16s, and go rip up the street for a week, youll have wood. then, throw on a set of standard (read pretty heavy) 18s, and go drive same roads for the next week. youll be begging to put the lighter(less leverage against car) wheels back on.
thats all im saying. and its much easier to support, and then dyno an AWD car with dynapack than it is to buy an expensive dual roller setup. this is why dyna was designed.
so now you see how i opine, it may not appeal to others, but in my head it is real life experience, and as close as i can get to what i would view as truth. later. dave

 

Thanks guys!!! This is the kind of feedback I was looking for. This site rocks!!! I have found a wealth of information concerning which mods work and which ones don't as well as other information about the car. For some one who has absolutely ZERO experience with Honda's this kind of feedback is invaluable.
