Thought i'd start another thread with this info to make it easily findable. Very very strong if you ask me. Both stock + with intake. AEM is not currently planning a CAI(only shortram for now) so this might be the best one on the market for some time. I guess we will ee when the icebox comes out.

dom

Tinky, so this means that the Auto TSX is losing 20.5% through the drivetrain. What was the average an automatic tranny typically loses? Do you have any other auto dyno's we can compare with? (M6, G35, 325, Accord??)

There's something unsettling IMO about losing 40 HP
At least we'll make 11+ back with a CAI.

Hmm...for some reason those dynos dont look right to me. The figures for max power and torque dont seem to corespond with the actual chart. For example it says max torque is 150..yet nowhere does the torque line touch 150.

Unless I am reading it wrong?

Count Blah

I'm no dyno expert, but it looks like its maximum torque of 150.8 ft-lb is reached at 2200 rpm at the start of the graph.

dom

fdl, its the pink line between 2 and 2.5K RPM. The stock peak occurs just past 2500RPM. So its gets its peak tourque it seems at about 2200RPM with the injen.

fdl

Right...and that makes no sense. The peak torque is definately not at 2200 rpms. To me the info before 3000 rpms is garbage...therefor that peak torque number is off.

EDIT: OK forget about what I said about HP..i wasnt looking at the whole graph But I am still confused about the torque #'s

fdl

See my last post ... peak torque isnt so low inthe rpms...and wouldnt a CAI REDUCE low end power...but improve midrange and top end power? Plus isnt the published peak torque for the TSX at 4500 rpms?

I am not trying to be sceptical...its just not making sense to me.

dom

Whats nice IMO about the injen tourque curve is the rougly 10 to 12 extra lb-ft you see between 4000 and 4500 RPM's. That a healthy does in the midrange. And there's also another 10+ HP just after 7000 RPM's

fdl

You know it looks like the TSX has lots of power well past 7100 ...even in stock form. I wonder why they didnt make the redline higher. I think with an ECU upgrade AND a CAI...we could see some hefty gains.

dom

fdl look closer, the "-" between 150 and 175 represent 5HP so if you line it up it ends up just below 170HP which makes perfect sense. You should probly print it and use a ruler to see it better.

Interesting pioint about the torque curve though. Having peak tourque occur at 2600RPM for the stock line does'nt make any sense. Maybe the dyno was off or something? Then again that would mean that peak tourque is about 135 @ 4500RPM which does'nt make sense either?

fdl

Ya domn...see my edit. My mistake on the hp thing..i wasnt looking at the whole graph. But I am still confused about the torque.

gogozy

but this is good sign!!! there are more power for us!! but i wuld like more offering so we can varify the graph!!

TinkySD

From all the dynos we've seen the stock figures by acura quote dare wrong. almost all k24s make peak torque between 2500 and 3000 rpms. The dyno seems to follow the AEM sri pattern. more power between 2000-2500 rpm, slight dip until 3k but then good chunky gains the rest of the way. Peak numbers are better in all cases with the injen though nd the dip is minimized. Remember that aftermarket manufactures tend to use very pessimistic stock dyno data to over exagerate the gains their prodcut gets. Assume that an auto puts down 160hp and 145lbft of torque. That's right online with estimates of 200-hp and 180lbft of torque. That's quite strong if you ask me. the old av6 lost something like 25% to the auto which is pretty average for most honda autos I think.

TinkySD

Here is an AT m6s with a gutted airbox/resonator removal.(equivalent of what moda way has done)




Caveat of course are these were done on different dynos.

dom

Your telling me a Mazda 6 Automatic only makes 159 HP at the wheels? Thats a 27.5% loss in efficiency compared to 20.5% for the auto TSX. Granted the M6 still has more tourque but that makes me even happier that I bought a TSX.

Tinky is the official dyno man

TinkySD

I'm addicted to tech info! I even got that cartest application today to fool with stuff. The m6s is severely overrated.(sounds like the rx8 and miata to me...) It actually is cranking mofre like 205hp but you get an extra boost in torque to about 200lbft. Obviously the auto is not as good as that in the tsx. The tsx also has more torque below 3000rpm(all the i4 haters need to take another look!). Of course the m6s has a good bit more midrange from 3000-6500 rpms with the tsx making power from 6500rpm to rev limitier.

fdl

So Tinky...or anyone...

Assuming we'll get 11 to wheels from a CAI...and looking at what was typically gained by putting hondata into the RSX...any guesses one what we could realistically see in the TSX with a CAI and hondata ECU?

Dare I say 20 hp to the wheels?

dom

Those are THE only two mods I'm interested in. 20 extra HP without looking riced out. That would be awesome. Well maybe a Throttlebody as well, but thats it. I'd also say that if a CAI gets 11HP on the Auto it should be good for at least 15 on a 6MT? The problem I see with Hondata is the cost, I've heard its about 1K CAD.

My wife was asking me what I want for my Birthday in December, and I hinted to a CAI, hopefully the injen or something will be available by then.

Santacruz

This is what I've been waitng for damn it. Like domn, a CAI and maybe an ECU are the mods I want to put into my TSX. I'll wait to see what kind of results the icebox comes out with and then decide. But these numbers are pretty impressive aa well as eye opening. Wish Honda would stop being so "safe" with their performance numbers.

gogozy

Does CAI get wet in bad weather?
i don't think i would get hondata, since it will void the warrenty..

AKay

Like ive stated before i think with all of the bolt on mods and a flashed ECU we can see 250-260 hp for the tsx.
This motor will be surprising with the power unleashed from tuning.

1) CAI only has a wet weather problem if you completely submerge the filter end in water. To do this, you'd have to be fording 6-8 inch deep water. Consequently, you can usually get a semi-porous "band" that goes around the engine-end or mid-pipe that just in case will allow the engine to breathe in such cases. Basically it's only a worry in flood conditions.

2) Hondata does not void the warranty. Getting the rev limiter removed and blowing up your engine by shifting at 9000rpm though, does.

gogozy

thanks!! :P
Do i need to remove bumper and any other parts to install the CAI?
have anyone try battery relocation kit? can i mount the abttery in trunk? will it get too cold in winter? i'm thinking free up some space in engine bay and cut some weight at front end..

TinkySD

yeah you have to take the bumper off, but i've done it and it's not hard at all...maybe a little nerve racking the first time though!

gogozy

arrrrh ..
took short cut install my PIAA (without removing bumper) and then accidently cut myself end up 7 sitches...
gusses at the end, i still have to remove the bumper... :'(
but not sure my wife would let me do it since we wait in ER for 4 hours last time... hehe

but the gain looks good, so CAI won't get wet while driving in rain, only when drive through water? what about added sound? man, can't wait for it.....

dom

I never had to remove my bumber when I installed my AEM CAI in my 98 GS-R? I really don't like the idea of having to remove the entire front bumber to get a CAI on. You can never get it to fit the same again.

TinkySD

I dunno about that...I think mine fits better than it did before

gogozy

sure the admin always have magic touch....

but that was one of my concern so i end up with 7 stitches.. look like i can't avoid it.. any suggestion onf battery relocation? oh, i will start a new thread on that..
thanks/

projectsx

you dont have to remove the bumper for install of the CAI i can get access from under the car . just remove the plastic cover under the car or the wheel well cover then the three bolts holding the resonator should come out.

gogozy

wooooohoooo
best news since black out......
think i will try remove resonator first!!!

projectsx

i just got off the phone with hondadata and they said quote" we dont have anything for that car and nothing in the near future but check out web site for updates."

dom

Thats exactly what I did with my integra and was hoping to do this time around. Thanks for the confirmation.

fdl

ok..


so is anyone gonna buy this thing and tell us if its everything it claims to be?

I want more power. Just 20 more horsies...thats all..and things will be perfect.

AKay

I would buy it now but im skeptical as to the performance numbers with the comptech icebox.
Maybe a few of us should email comptech and ask for a dyno because we are seriously comtemplating a group buy on INJENS.
maybe at least if we get a dyno on the icebox we can make the decision on performance gains now or more later.
AKay

projectsx

i have it on my car and driving it daily . no problems love this bad ass cai . i will do group buy as soon as it is avalible to ship . injen expects another week or two before it is ready for shipping

TinkySD

projecttsx: do you notice any loss of torque between 2-3krpm? The dyno plot doesn't go quite that low although it does have toque slightly lower at 2500rpm. The AEM SRI shows a signficant drop in that range which is somewhat an issue because that isa very normal rpm for freeway cruising.

gogozy

mmm, yes; it of my concern too, i just don't know if the dyno was not accurate at that rpm or not since i am not an expert.... any expert

projectsx

very little notice but starts pulling at 3k rpm and just wants more after that. when i use the sports shift i like 3rd gear i pulls strong. now i feel like i can take anyone on the road.

AKay

does anyone know the est price on this intake?
My performance shop would want to order it direct and install it themselves to warranty the work.
AKay

TinkySD

it looks like a pretty good product. Keep us updated on when it comes out. I might even buy one....
