Just browsing through different threads on this forum and I noticed something. Huge hp and tq claim differences between many evo owners with similar mods. I also notice that when someone makes a post in this forum on how much power they made on a dyno that there is always someone else that calls BS or says that they made X amount more hp or tq with the same setup. Why is this? We obviously know that every dyno is different and evey car is different but WOW, that different?
So I purpose something. If yer gonna bash someone elses #s or post dyno #s then you have to post baseline #s too before mods to compare. If you cannot do so then don't post #s at all unless you have something to measure them with like trap speed or something.
To me blurting out 360hp and 350tq with a IX and only bolt ons means nothing to me unless you have some sort of baseline or track time. The next guy that posts 315hp and 300tq could actually be making the same power with just a different dyno. And thats what I mean with the differences in #s. Any thoughts on this?

The way this forum member did it is what I believe to be the right way and most accurate way of doing it even though he did not post post baseline #s, he did post track times:

Yeah, we say that all the time, but many people don't pay for a dyno before AND after, and some just never think about it. Also, many of the dyno queens never go to the track, so there is no comparison at all. It sucks, but that's how big message boards work. If everyone could at least show stock vs modded dynographs on the same dyno, then the world would be grand.

PS. "purpose" should be "propose."

 

Define huge HP and TQ differences? Are you talking 20 to 30hp, I wouldn't consider that huge at all, especially when there are so many different outside influences effecting the numbers, such as location, octane rating, temperatures, different dynos, different tuners, and the list goes on and on. So it is very easily understandable why there would be different dyno numbers from the same cars with similiar mods. This isn't just the case with EVOs, but all cars from my understanding. Are you going to tell me that LS1 and LS2 GTOs with similiar mods dyno within 5 to 10 whp of every single time no matter what dyno, bullsh*t dude! Sh*t stock GTOs fluctuate up to 20 to 30whp (sometimes more) from each other, depending on the conditions. It is safe to say, that a EVO IX with simple bolt ons such as TBE, Intake/Filter, MBC, Fuel Pump and Tune should be over 300whp on most Dyno Jets. Of course some will put out 310whp, some 320whp, and some may even put out 350whp, but like I said it depends on the conditions, such as location, octane rating, different tuners, and so on, and honestly not all cars even if they are the same cars are not created equal. Some EVOs are just more powerful than other EVOs.

 

If only this were a perfect world. Sorry it is not, and I try not to look into things too much. If I see one EVO that made 350whp and another 320whp, I do not automatically think to myself, wow that 350whp EVO is so much more powerful. I think, wow both of these cars have made some good power. Also I understand track numbers can help, but like every car community out there, the EVO community is plagued with some horrible drivers (myself included). So yes the 320whp EVO may run so much quicker times than the 350whp, but you know what the 350whp EVO could still be the more powerful car, but the 320whp EVO has a better driver. So you see not even track numbers can help tell the complete story. But when it comes to dyno, what I try to do, is compare numbers with cars that have been dynoed on the same dyno.

 

^^^ yeah, I caught that too... but I knew you'd be the one to comment on it...


OP, no matter how many times it has been said that a dyno is a tool for measuring change (before mod vs after), people on here still are jumping up and down like apes over the biggest numbers --


(Note to self: go immediately to TurboTrix or TheShop and get dyno-tuned at 25psi on pump gas to get the absolute highest numbers possible, then turn boost back down to a sane level and drive around with a smile, knowing I have the biggest numbers...)


Another thing that pisses me off is why the hell does everyone on here insist on talking about PEAK #'s, when they will still get raped by a car with lower numbers but more power under the curve...

I swear, some things I will never understand...

 

3000ways, you keep missing the point in this, and I've explained it numerous times. Lite Spd was _not_ talking about "track times." he was talking about trap speeds. Yes, of course, driving ability will have a major effect on ET, but we're not talking about ET. Trap speeds are largely unaffected by driving (relative to ET). In fact, some of the BEST drivers will cust such nasty 60's that their trap speed will be a little LOWER than lesser drivers with the same power.

 

Its not 20-30 hp, its more like 45-50 hp. To me thats alot. And I've also noticed this....many Evo owners have very different views on what 350 hp really is. Does it make the car trap 111mph or 116mph? On the street from a roll the difference is enough to get walked and beat pretty good.
To eliminate some of those differences between hp #s on cars would be pretty easy. Use SAE corrected figures on dynojets (since the dynojet seems to be the most popular choice). Not only will you get rid of bolt on Evo owners claiming 350 hp, you will get rid of the guessing game. I bet the numbers and actual power levels between cars is closer than you think. There are no magic bolt ons out there and no magic tuners either. I doubt there is more than a actual 15 hp difference between stock Evos of the same year. If there is, its probably more of a mechanical problem than anything else (minor boost leak, spark plug, whatever).
I don't want to get into GTOs but you are wrong about 20-30 hp differences on GTOs. Using the same model year and same trans GTO, you will get hp figure differences that will max out in the teens in terms of hp or tq. Most dynojets are already set up with SAE corrected factors so no guessing game here. If a GTO owner boasts 30 hp more than average on bolt ons, many will call BS or show me the baseline or trap. Not applaud you for doing such a great job at the dyno.

 

LOL, I didn't know this was a spelling bee.

 

i have 333whp 380 trq and smoke a 06 gto from a roll 5-100 if that means anything.

 

You may not look into it too much but many Evo owners do with questions like:

Why did my Evo not make the power it was supposed to?
Why am I down 50hp?
Did I buy the wrong parts?

I know every Evo owner hasn't baselined their car, but why can't they use someone elses baseline for reference? Because everyones #s are too different. You have to know where you started before you can proceed forward. And to me if you don't use corrected #s consistently, you will never know what you've gained with your hard earned $$$.

 

SEE WHAT I MEAN!!! A post like this tells me or anyone else nothing.

 

Numbers are just that, numbers. Nothing is proven until you get on the 1320. Dyno #'s are never the same, **** varies due to weather, humidity blah blah blah. Parts react differently to other parts and on different cars. So many variables, too many. All it comes down to is what happens after the light turns green.

 

This is true. We can posit different arguments about the variations of #'s as it applies to mods,weather,driver error, etc. However, the only thing (in my opinion) that really matters is whether or not I'm in front of you when we get to the end of the finish line.

 

 

I think instead of posting dyno #'s, it would make more sense to post "full" time slips. In most cases but not all, we could make a more accurate guess on "actual" horsepower someone probably has as long as all variables are listed such as weather conditions, elevation, etc.. As for those who don't have a track near them to run, I can understand the continuing need to post dyno #'s without having a slip. Or, for those that are showing gains on the "same" dyno from recently installed parts.
