I think it takes at least a full tank of gas before the ECU advances timing and takes full advantage of the premium fuel.

I am planning a dyno session this coming weekend, April 3rd. I'm an automatic with an Injen cold air. So I too will have to see what the car can put down.

Let us know what your 6spd puts down

two things to remember:

1. dyno in 4th gear!!!!!!!!

2. Make sure they give you your SAE corrected numbers, not std!

Thank you for putting out the bucks for that all important pre-mod dyno. It will be nice to get a real measure of the gains, not just a post-mod dyno and a guess.

Good job!

Yeah, I didn't get to dyno mine before I put my intake on it. I'm going to dyno it later before I do exhaust or anything else. I just have done the AEM v2 CAI.

it's considered "good practice" to dyno in the gear ratio closest to 1.00:1. For AV6 autos that's 3rd, but on 6spds it's 4th. In the end it shouldn't make much difference anyways because the dyno adjusts for the overall ratio, and as long as you compare baseline vs modded dynos done in the same gear it's all good.

Some cars run a straight 1.00:1 "overdrive" gear but just run a very tall 2.xx:1 final drive vs a more common 3.xx:1 on a lot of cars, or 4.xx:1 on a lot of Hondas. For those cars you do need to dyno in one of the lower gears anyways. You'll either be hitting the speed limit of the dyno, or straining the engine and getting it extremely heat soaked and losing power by the time it manages to pull up to that high of a speed.

Time to post my results...just a recap I have a 2004 V6 6-speed.STOCK! I use 91 octane fuel The tem was prob 12C sunny. Done on a rolling dyno with SAE corrected hp and torque.
I did three runs. The first two were the same, the third was removing the intake flex tube that attaches to the air cleaner. I wanted to see if not having the restirctive filter and everything would give more power. My computer is F%ckn around with me right now and I cannot uplaod the actaul dyno sheet, But I will tomorrow. For now I will give you the numbers

First run was prilimanary with the same hp as the second,

The second run yeilded [email protected] 6200rpm,
193.6ft/lb5200!

The third run is when I tried the method I decribed above with removing the flex tubing from the air filter box...
[email protected], 188ft/[email protected] what a difference.
The guy was saying that whne the air travels in a short path throught the intake it tis very turbulent and that' what causes the drop. Plus as you with see when i get the dyno posted you'll see how eratic the power curve is.

Too note for those who are scetical of results my un corrected hp would have been 219.5hp.....

Never mind computer coment here it is..

Thanks, those are pretty respectable rwhp numbers. Will be anxious to see the results of your mods. Particularly if you do a CAI, starting to rethink my position on CAI after this article in TOV,http://www.vtec.net/articles/view-ar...icle_id=214692

So we are probably loosing power with induction systems!!!!!!!!!! Great stock numbers... Can you describe this piece that you removed any more? You say the flex tubing? You mean the actual tubing that went from the airbox to the throttle body? What did you use in its place? Were you just allowing air to enter the throttle body without any tubing?

Thanks

Roadmaster, I doubt it..

I think the problem was the air were not "controlled" to be flowing in orderly and efficiently.. it all have to do with the design of the tube as well...

I understand... It does make sense, an open throttle body has no true control of the air. But I have still been rather suspicious of cold air inductions systems and whether or not they do provide gains or not. If I remember correclty our buddy "torquie" dynoed his car with an Injen induction system and produced the same numbers at the wheels as other stock cars (ie VTEC.net test car)

I know some cars are faster, others slower... I just hate to think I am potentially loosing power with the Injen intake. I remember a long time ago sending a letter to Injen. I recieved a reponce that my letter was being resent to a more appropriate source, but nothing else ever happened.

Torquie is an auto and will dyno at a lower whp when stock. The intake showed that his car puts out as much as power as a stock 6spd.

Torques car made 196hp and likewise an automatic 2003 V6 sedan on VTEC.net produced the same numbers. If I remember correctly the stock 6-speed produced 212hp, almost exctly what SAM6's car produced.

Maybe its time to sell intake and go with a 6-speed intake

So your saying that Torquie dynoed as other stock 6spd Accords or autos. If you meant autos I stand corrected.

Oh and Torquie IS the guy on VTEC.net.

No, If I remember correctly Torqueaholic dynoed about 196 horsepower with his 2003 Automatic Coupe. His car, at the time was equiped with the Injen Intake System.

The Temple of VTEC car was a 2003 automatic Sedan, bone stock. That particular car produced 196hp at the wheels as well.

Now these were two different cars and two different dyno sessions... To be honest I don't know what to believe except that I know my car isn;t as strong as others (some stock) and I am beginning to reconsider my installation of the CAI

How come you think your car is not as strong as other?

S.A.M6 great dyno results! I will be doing my stock dyno in a month or two; I hope my results will be the same (if not better ).

[email protected] is the reason why I think my car is not as strong. The MPH just doesn't support the power. I always have blamed the track Indianapolis Raceway Park in Indianapolis... Which is notorious for poor times.

I need to get my car dynoed and see exactly what it is putting down to the ground. That will prove if my car is strong or not.

good numbers! your pretty much getting what Vtec.net got stock-5whp, not bad! torque numbers are spot on, yes. Did you dyno in 4th gear? I'm guessing yes. all in all good job!

well, I know for a fact that just a CAI, isn't going to produce the "20whp" on a 6spd, that some aftermarket companies have us believe. However, the reason, you "lost power", could just be that your engine got kindda hot! I have dynoed the most out of any member here, and let me tell you that the J series motor LOVES being cold! so, unless you were monitoring coolant temps, live TOV does, then Yes, after you dyno a while, its not odd to see the huge loss in power, because the ecu pulls timming due to heat soak. When we wait for like 20 mins, and then dyno again, BAM, the HP comes back!

yeah, I was kindda the first on here to discover that they are not doing anything, alone, on the car, but if you remember I got FLAMED big time for that post! This car will produce more power, but as russianrsx demonstrated: Not without exhaust+ecu.
