Stokeless_TSX

I really wanna see a dyno with a CAI, Header and an exhaust. Along with Hondata.

vwong

Ok, since my site is back up, here is the dyno plot for my car. Again, it was dyno'ed at Church Automotive Testing (same place Hondata did theirs). And since I forgot to get a print out from him, but I got the raw data. I plotted them in Excel.

PixelHarmony

I thought lift hits at 5k?

Stokeless_TSX

vwong's dyno is stock.

sauceman

I really love your schemes!

Stokeless_TSX

Just evil isn't it?

tekn0mage

Here's my Dyno. I will post another one later today. I am getting an Injen CAI installed now. Will do two more dyno pulls once installed.

2005 TSX 6MT w/ 1980 miles

Mods: 2004 Hondatafied ECU, Comptech Exhaust

tekn0mage

With an Injen CAI vs. Best run without Injen

Dan Martin

Wow the injen gains are very impressive.

gfd1182

does anyone know when the comptech supercharger is coming out?

04 TSX
Comptech headers, Exhaust, AEM SRI
W/Navi Nighthawk Black

Dan Martin

Last update had it at early May.

Stokeless_TSX

Then when May hits it might be June. Don't hold y our breath. Just hold on tight and wait.

This is a pre and post Hondata reflash dyno. The only component change was the Hondata reflash.




K&N CAI
TB bypass
Hondata gasket
Hondata reflash
DC header
Stock exhaust
5700 miles

Stokeless_TSX

Just a fatter curve what happened to 200 whp Johnny? hehe. I bet it pulls hard at 5500 though huh?

kangjin

Here's pre-reflash vs. post-reflash. I also added the hondata gasket and coolant bypass between dynos, so take that into consideration.

Numbers still seem really weak to me, might have to hop on the DC Header bus.

taewlee

is your car an auto? and did you dyno at the same place as jtso?

kangjin

sadly, it's a 6mt with 15.6k miles and no problems. and i dyno'd minutes before johnny at the same place.

TinkySD

Kangjin: your before dyno is just an injen right? Regardless of your peak numbers look at all that extra torque you gained below 3k rpms! Gains like that is what make me consider this mod for my auto.

kangjin, I notice your dyno curves seem to show a little hesitation. You might want to check the condition of the spark plugs, as they might provide clues to the mysterious lower number. While you have the plugs out, a compression test won't hurt either.

sauceman

JTso, your dyno was really with only Hondata, nothing else, no TB bypass, Hondata gasket, not even CAI?

xizor

I believe he has all of the above mentioned plus DC header.

xizor

were all of your runs the same? did you rule out heat soak as a factor if the first run was the same as the last?

The dyno comparison includes the following mods. The only difference is one with Hondata reflash and one without.

K&N CAI
TB bypass
Hondata gasket
Hondata reflash
DC header

tekn0mage

JTso thanks for providing that great comparison. It's quite a bit of work to dyno your car at every mod. I missed my baseline run with no mods Could you tell us how many miles are on your car?

I was happy to see your numbers. Makes me think perhaps I got a little bit of a freak on my hands. Our peak is right around the same, except you have a header, gasket and tb bypass goin on. Makes me wonder what I'll peak at with a header.

My car @ 2k miles (injen cai + comptech exhaust + hondata) = peak 180.79 hp / 158.06 tq

versus your peak of 181.4 / 157.69

Just a comparison thats all not trying to prove anything... hehehe.

taewlee

i wish someone would dyno with injen cai, dc header, and hondata....

JTso

My car has about 5700 miles. do you have the actual dyno files? If you do, send them my way and I can plot them together using dynojet viewer for comparison.

tekn0mage

yep I have the actual dyno files. Brought my little mini USB flash drive with me hehe. I'll send them your way via email perhaps?

How do you want it...

You've got pm.

tekn0mage

I am looking at Kangjin's dyno... I bet he ran that in 3rd gear. The numbers are a little more erratic than a 4th gear pull. My bet is that it was done in 3rd gear.

That would also explain the slightly lower numbers than par.

kangjin

both runs posted were the same, ~171.2 max hp. the first run (like last time) my tires slipped around 5k and screwed up the graph.

they were run in 4th gear every time.

the before dyno is with an injen cai and fujitsubo catback. after is +reflash +hondata gasket +coolant bypass.

i'm thinking about the dc header, and maybe dynoing the current setup -fujitsubo +stock exhaust just for kicks, but the dyno fees are adding up.

vwong

Exactly why I think dyno'ing on a Dynapack is better. You can really eliminate these kind of things, and get a more consistent dyno. Just my humble opinion.

Here is a comparison of tekn0mage and my dyno results. Note the A/F and how it affects the gain when it becomes rich for both dyno results. The blue is tekn0mage and the red is JTso. I have to say this is a very close comparison.

vwong

Here are my dynos. Before and after Hondata reflash (in a totally stock engine).

sauceman

I am constantly amazed at how "handsome" the Hondata power curve is.

iamhomin

vwong, you're only modification is the Hondata and you're getting those numbers?

Dan Martin

Don't forget that dynapak dynos read a little high but the gain over the baseline numbers is quite impressive. +22 hp and +21 lb ft at around 6000 rpm.

dom

Yup, One of the Ricer mags dynoed a stock TSX on a Dynapack at 180WHP when it first came out. His car is putting down some nice power though.

TinkySD

Sweet gains! I like how the torque peak after is at 3k rpms, great for daily driving.

TinkySD

JTSO -- he just has the injen and you have dc headers and injen correct? Interesting that they are so close while he doe snot have headers. I'm wondering if a different set of headers(comptech for example) would change the results.

JTso

TinkySD, he has Injen intake and Comptech exhaust, and I have K&N intake, DC header with stock exhaust and Hondata gasket.
