I just got back from the dyno. A good experience, but not exactly the results I was hoping for having the Comptech I/H/E, RT Cat, Hondata Reflash and Heatshield. I have video of the runs too, which I'll be posting to Google Video as soon as I finish editing.

If there was ONE positive result from the dyno runs, it was that I learned the quiet tips have almost ZERO affect on the performance of the car. That was good news IMO.

It is also worth noting, I only gave the car about 15-20 mins to cool off. The intake manifold was still warm to the touch.

First Run, no quiet tips.
Summary:
189.0whp
160.2 ft lbs.
a/f ratio: 13.5-14.5


Second Run, no quiet tips (car cooled off for 15-20mins)
Summary:
189.5whp
161.4 ft lbs.
a/f ratio: 13.5-14.0


Third Run, with quiet tips (car cooled off for 5 mins)
Summary:
188.8whp
160.5 ft lbs.
a/f ratio: 14.0-14.5

 

One other cool thing... right next door to this dyno shop was a place that builds Mustang Cobras and Nobles.

 

those look like some good numbers!

in terms of crank power this would be...?

 

~223hp at the crank if you use the 15% loss via the tranny

 

what numbers were you hoping for?

Looks good to me, but I am a little uniformed with what you should expect from your mods.

 

time for a cold air intake to increase that power.

 

Do you happen to have a baseline dyno with the car in stock setup to compare?

Otherwise, those look like some decent numbers for the bolt-ons. I've seen some other TSX's dyno at lower numbers with similar setups.

 

Yeah, I think those are good too. If you were hoping for higher numbers, I wouldn't worry about it. That dyno might read lower there others. Too bad you don't have a baseline dyno. The big thing you want to look at is the improvement of your own numbers.
You should ask the dyno operator if he has any other TSX dynos stored.

Can't wait to see the video though! And you going to do any more engine mods? Pulleys?

 

he was hoping to be over 200whp. I think the pullies would put him there too.

 

Yeah, pulleys would put him right there.

What was the outside temp? Temp can have a big effect on the dyno.

 

This crossed my mind after I got the results.

BTW, I do have the Comptech Icebox.

 

Yeah, wut was the outside temp?

 

dynos in the states must be calibrated differently to the ones in Australia. If I reached 140kw (190hp) at the wheels with just those mods I'd be over the moon. For reference a stock s2000 here would only put out no more than 130kw and a modified DC5R (including ecu tuning) about 125kw.

Anyway, don't get caught up on the numbers - I'm sure you've felt the difference the modifications have made and enjoy driving the car more, and thats all that should matter.

 

I should try doing dyno on mine too. Wandering how much it'll push with auto tranny.

 

Best Dyno Run

Dyno Run with Quiet Tips <---- something is f'd up on this one. Going to redo.

 

Roughly 75 F.

 

Thanks for the perspective. That does make me feel somewhat better.

 

I know you have the comptech icebox and the injen intake and the k&n make more power which you know. you want to buy my injen cause i am thinking of ordering the gruppe m intake or mahybe I should just get the supercharger and call it a day.

 

The sec clip didn't work for stop. It just stop half way. I like the first clip, really like the sound of it. Can i see some picture of your car and a close up picture of your exhaust?

 

Check my cardomain site; link is in the first post. If you want something more specific, just let me know.

I'm working on fixing the second clip. Google Video is very pissy with me at the moment.

 

Calling on JTso or others to comment on the a/f ratio. The tuner guy seemed to feel it was just a little too lean. My thought is its Hondata being a little conservative. I was thinking the 12.5 to 13 ratio range.

 

Yeah it does look a little too lean. Should be down a little lower in open loop mode. You have your a/f ratio graph? I think JTso has some of his around. You should compare your numbers to his.

And Hondata usually would make it more rich to be conservative I believe. This will help protect you from running too lean. Being lean aka closer to 14.7 usually generates more power though.

Hopefully JTso will come around to comment more though. My knowledge of a/f ratios is mostly with my forced induction setup.

 

Yeah, I have all my a/f graphs, just didn't post them. Guess I need to start scanning

 

you should get both though a gruppeM is more rare than a comptech supercharger these days

yea i noticed people do get caught up with numbers, different dynos, different days its hard to compare. Also forget to mention, power curve looks great very smooth.

 

A/F Ratio Graphs (FYI, don't pay attention to MAX A/F... owner said its printing that same number all the time)

First Run


Second Run


Third Run (w/ Comptech Quiet Tips)

 

Okay, here is the update link with the Quiet Tips in:

Dyno Run with Quiet Tips

 

nice videos...although, i listened to them several times and could never pin point when vtec kicked in

 

In the first video... @ the 12.5 second mark (non-Quiet Tips)
In the second video... @ the 19 second mark (Quiet Tips)

Subtle, but its there.

 

mod, props on the clips and graphs. i can imagine your frustration ... i have an 05 auto without a reflash of course, so i'm too scared to get a dyno (then again, i don't know of one in the tampa bay area). i would expect that the rt cat would've put you over the top. maybe it's time for a set of pulleys. some people notice a bit rougher idle, but i didn't - could be because i installed hks circle earth ground wire kit at the same time. one thing's for sure, the old tsx is exponentially more fun to drive with my mods, so number might not matter too much after all!

 

is tanabe medallian touring exhaust quieter than comptech with quiet tips?

 

With the same given parts (I/H/E and RT Cat), I'm pretty sure the Comptech with quiet tips is more quiet.

 

I'm not a dyno expert by any stretch, but it seems to me that a chassis dyno's only real value is in comparing "before" and "after" runs on the same dyno under similar conditions. My best on a Mustang dyno was 184 whp, that was a 25 whp increase over my baseline, meaning I added roughly 30 bhp and that was exactly what I expected.

What was your baseline, moda?

 

Some Weak sauce ### sorry to say.. How many miles do you have on your ride Moda-Way?

 

60k and thanks!!

 

Whatever the stock 04 TSX 6MT is.

 

That is lean. Stock, the K24A4 also runs lean around those numbers, so it's likely not a problem.

 

moda_way, you know I will ask for the actual dyno right? If you have them, I'd like to compare the curves of the different setup.

 

Yeah, I tried. They ran the dyno s/w off of a Windows 98 platform and the USB Flash, if you remember 98, isn't support like USB out of Win 2k or XP. Of course their burners weren't working either. Typical grease monkey shyt. I actually had to fix some of their stuff. Sorry, I don't have the data files.

 

That's too bad... No one uses floppies anymore?

Btw, I think moda's a/f is a little on the lean side during WOT. The a/f on my setup got a little leaner when I have the test pipe on. Here is the a/f comparison.

Red = test pipe
Blue = high flow cat

 

Just watched yur vids, just realized how much louder my HyTech is compared to other set-ups out there! BTW, nice numbers!
