I really don't know much about those. I do know that the Dyno Dynamics machine is known as the "heart breaker dyno" because it reads so low compared to others. The operator at the shop told Tony and I that FI 350's that put dyno in the high 300s on his machine will read mid 400s on DynoJets... so you can see how that'd be heart breaking.

There are a lot of factors that are involved, and it's more like an 11whp difference. IMO that sounds about right on this machine because the only other mods that he has that would really give him more power over me are his HFCs and CBE (Berk and Stillen). And he has the Stillen G3 intakes which probably, under totally equal conditions, are identical to my Injens.

And, keep in mind that with his CBE and HFCs he will whoop the crap out of mine in mid-range power. It's not all about peak hp.

I thought you said he ran 270, and you ran 265?

It still should be based on percentage gains:

a dynojet stock runs about 280, tony got about 10% increase with his mods that put him to 307...so on a dyno dynamics if he ran 258 stock, he still should have seen a 10% increase of 26hp with a result of 284.

same with the injen, if they dyno'd 280 stock on a DJ, 15 hp is roughly 5%. so you should have seen 5% gain over 258, or 12-13hp.

Either way, you blow thedreamer's results outta the water! :rofl2:

The problem with that is that you are working under the assumption that power is a linear measure, but it's not. Since it's not a linear measure and since both dynos use different assumptions in calculating power output, we can't compare that way.

What we can say is that, on a DynoJet, expect around a 15whp gain. On a DynoDynamics machine, expect less. I'm sure a Mustang dyno would give us totally different readings as well.

% isn't linear. It is the way I have read nearly everywhere to analyze gains on any dyno. % increase over base.

You and me both! The garage where the dyno is has a Dynojet though...

GARAGE808 :: HONDA AND ACURA TUNING

Not even sure when I will receive the intakes, they haven't charged me yet.

IMO, he had no net gain or loss when you factor in error. If he reset his ECU, maybe he'd see a small net positive gain. But I'm in the camp that believes that the short-tube intakes are NOT going to provide any measurable gains over the stock intakes, which we have proven are very efficient up to a nearly redline. Long-tube intakes don't even see gains over stock until very high up in the range because the stock system is that good.

:iagree:

btw, not trying to start an argument or anything, just going off of what I have learned about dyno's in the past.

I wish all dyno's would get calibrated to the same measurements so we didn't have to try and compare apples to oranges :shakes head:

You know what I mean... Dyno A doesn't consider one unit of power the same as Dyno B. % gains are going to be most useful if you're comparing two different Dyno's of the same make. I don't really think that kind of comparison is going to hold up across different dyno's since their methods of measuring power are totally different. Not to mention all the correction factors that go into a Dyno Dynamics vs. something like a DynoJet which is very basic.

Oh, no problem at all! I think it's just important that we all understand the differences involved. I don't want people saying, "Injen says +15whp but Steve only got 6.9 whp, they are totally lying!" Or people saying, "The Stillen G3 gets +18whp but the Injens only get 6.9whp!"

That's just not healthy.

true, and my knowledge of both dyno's is still limited, as I have not taken the time to dyno my car and learn the differences. Just seemed to me like something was out of whack when Tony as only 5hp higher than you with full breather mods.

anyways, like I said, not trying to argue with ya :tup:

Guess I need to just decide to go with Injen or Stillen now, gains look good, will probably wait until my exhaust is one my car before I buy a different intake. Thank you for doing the dyno and getting results.

:iagree:

thats why I wish we could get some dyno shoot-outs on the most popular setups. manufacturers all mail their setup to one person who dedicates a day at the dyno. do some baseline pulls, then part a, then part b, then part c...etc.

compare all the graphs and you know you are finally looking at consistent data.

Until then (which will likely be never), go with your gut feeling on which part will work best for you!

Well I'm out for right now guys, I have to go and pick up my new living room furniture. Be back to play later. :)

ur dyno results is going to be the most interesting one...... r2c is the intake of the hour now

good luck with a new setup dreamer, hopefully takeda offers to reimburse you or something like that.

takeda is short for take da shiet out

Any idea when R2C is coming out with their intake for the 370? I know they were testing it last week. No news is not good news....

:icon18::rofl2:

it's already out bud, jbms has a group buy

Checking....

price is not bad, i got a better deal though

Merci!

Bienvenue !

Updated Post #1 with my Results and thoughts.

for those who want to see how the black intakes look like installed... all thanks to Lou from Amplified... if u want em black he got em... :tup:

they look good. still wanna see Dyno sheets though.

Dude I ordered mine but I gotta wait a minute for them to come in on the 27th! Lou has got them on Hand! Damn!!!!!:mad:

BTW they look Bad A$$!

Black looks great! Thanks for pics! + rep

I'll put them up as soon as I get them... hopefully tomorrow morning.

Very nice!

Awesomeness, thanks so much for doing this.

Just curious if anyone else noticed that 258.1 + 6.9 does not equal 265.4? It would seem you gained 7.3HP or your current max is 265.0HP. I'm hoping for the 7.3, cause that means your car is even faster than you thought, LOL.

:icon18: Wow I didn't even notice I messed that one up. Max is 265.4... not sure why I ran with 6.9.

I can't believe I work in finance. Guess that explains the last year or two. :icon18::icon18::icon18:

lol, I'm an accountant and have been known to do similar things outside of the office :tup:

Not sure if im a fan of the black, aside from the INJEN logo, they kinda get lost in the bay. Looks nice though. Ill be going with the chromies.

Man, I hate accounting! I doubled in accounting and finance and am very happy I did not have to become an accountant. :icon18:
