I was down at Comptech this past Wednesday getting some stuff done.
-Had the Denso Iridium IK22 Spark Plugs installed
-Had another bung put in my header for the O2 sensor, I'm running a PLX M300 to monitor my air/fuel ratio
-Found out there is already a spot for a boost guage hose in the intake manifold so I don't need to T tap into one of the other lines
-Did Dyno runs, Comptech made sure my TSX was still running well.

Video of my Dyno run (Taken from 2K RPMS to the Rev Limit):

I'm a little disappointed in the Dyno runs. It was really hot that day. The dyno room temp read 104 degrees with everything running. We're having a nasty heat wave in NorCal right now. Last time I dynoed it was February so it was probably about 40 something degrees cooler. That 40 degrees difference in temp lead to lower numbers and my car producing less boost. I was producing 4 lbs of boost instead of 5 lbs of boost.

My peak HP was 218 whp and peak TQ was 160. These numbers are a little lower than my previous dyno with SC. In my last dyno, I had 223 whp and 165 TQ peak, but I've since added the Random Tech Hi Flow Cat, so I was hoping for higher numbers. Considering the big temp difference I'm not surprised though. Temp makes a big difference as illustrated by JTso in this thread: http://www.acura-tsx.com/forums/showthread.php?t=31171

Green = February Dyno - 60 degress outside, Comptech SC, Icebox, DC header
Blue/Red = June Dyno - 104 degrees outside, Comptech SC, Icebox, DC header, Random Tech High Flow Cat
Difference in Temp = 44 degrees warmer in the most recent dyno
Components added = Random Tech Hi Flow Cat

New O2 sensor in header w/ bung from Comptech Header


Temporary Mount Location for PLX until I figure out where I want to put it.


Rest of the pics I took:


A customer's ride they just finished:




Comptech's Supercharged TSX 6MT test car


Asked them about the grill and it's straight custom. They made it themselves and said it took awhile to make so it won't go into production


Machine shop - Every single part is custom made welded by a real person, no machines. In this pic the guy is making a TL exhaust.




Sweet ride I saw in SoCal (Completely off topic, I know )

Could a mod please fix the above. I had the colors flipped. Green is the newest dyno, from Wednesdsay, in the hot weather.

Blue/Red = February Dyno - 60 degress outside, Comptech SC, Icebox, DC header
Green = June Dyno - 104 degrees outside, Comptech SC, Icebox, DC header, Random Tech High Flow Cat

On paper that doesn't look like much of a difference from stock. However, how does your car feel with the SC on it? Is there more of a difference in the midrange? 6th gear? Your impressions?

jmathew34

nice pics, sound really nice!!

Tsx536

It's night and day difference in terms of the feel.
Also. I have an Automatic, so I don't have 6th gear.

My car baselined at 165 whp and 138 tq in cold weather. Here's the dyno for those runs. Baseline vs. Modded (w/ no hi flow cat)
W/ the SC and other mods it hit 223 whp and 165 TQ.

These numbers are all measured at the wheels on a Dyno Dynamics Dynamometer:
The red line is a completely stock Auto TSX with OEM ECU, OEM intake, OEM header, OEM Cat, and OEM Exhuast.
The blue line is a TSX with Comptech Supercharger, SC Hondata Reflash, Comptech Icebox, DC Header, OEM Cat, and OEM Exhuast.

Peak Horsepower is now 223 whp, up from 166 whp stock.
The Biggest horsepower gain was 59 whp @ 7100 RPMs

Peak Torque is now 165 ft/lb, up from 138 ft/lbs stock.
The Biggest torque gain was 43 ft/lbs @ 7100 RPMs

Thanks Yeah I just used my Sister's Sony T5 camera for the video, so sorry if the quality isn't great. I'll try to shoot a short cabin video when I have some time. That way you can hear it from that point of view and also see the PLX.

iterry

Wow, that is a difference. Any reliability problems? Now that you have had it a while, any overall impressions?

Tsx536

No, haven't had any reliability problems. I have had the SC for probably about 15,000-17,000 miles now. I have impressions posted in other threads. So do a search. There's also a lot of info in my main SC thread:

Acutally, I had it right the first time

Green = February Dyno - 60 degress outside, Comptech SC, Icebox, DC header
Blue/Red = June Dyno - 104 degrees outside, Comptech SC, Icebox, DC header, Random Tech High Flow Cat

Cool, I'll check it out

NJTSXMan

104 degress? Jesus.. I couldn't survive over there. I would die if it is above 85 degrees and i'm not at the pool or beach.

In any event, I was curious as to why you had the Denso IK22 installed as opposed to the IK24 that comptech had sent another TSX SCer who was having some issues.

It is interesting that the heat caused it to only pump out 4lbs of boost. I would have thought it was something with the belt.

I'm really impressed with the details I've heard about the Comptech supercharger package... Especially considering how the stock TSX is already borderline when it comes to compression and tendency to ping. It makes me secretly want to buy one or at least have access to a factory sponsored tuner car (ala AMG for Mercedes or M for BMW) which has one of those bolted to the head.

How sensitive is the engine to fuel quality--does it ping much when it is really hot outside?

Thread cleaned up and fixed dyno numbers.


Yeah, hot temp will kill performance quick. It's especially danger for a SC setup without intercooler.

That S2000 is the sexy sweetness. Oh Honda, why are so many of your cars WWD?

jmathew34

any thoughts on if the ethanol mixture in gas will hurt a s/c'd tsx?

I can hear the audio but can't see the video. It sounded like a fighter jet taking off!

sho-one

so did they replace the spark plugs for free? What are they going to do with the rest of their customers, are they going to contact them. Hmm looks like I'll be giving them a call on monday. By they way, did you install a boost gauge?

Tsx536

Yeah it was way too hot. I wish I could have dynoed on another day but I happen to have that day off of work and I was mainly there to get those other things done.

And I thought the low boost would be the belt slipping too but it wasn't. We checked it in between runs and by tightening it on the 2nd run we got 4.1 psi instead of the 3.8 psi on the previous run. So by tightening it, we gained about .3 psi of boost.

The spark plugs weren't free, but they took care of me

frgn sweet k-rock! Lucky!! Comptech what??? Great pics and write up my myspace compadre. Thats like almost like 80hp more than my turd dyno'd. Ride looks good my man!

Tsx536

So how much HP/TQ would you guess a 44 degree difference in temp would make?

Yeah I think you gotta have Divx in order to watch it. I'll have to figure out a different way to encode it, or maybe even a different host.

Tsx536

I think the problem is going to be engine management. Here's an RSX guy that ran it without changing the turn on his Kpro and he said it automatically made him run really rich. He changed some settings using the K-Pro to remove some fuel, but unfortunately we don't have anything to do that.

Kenny, how is the transmission holding up to the extra power?

Tsx536

I just put the video up on Google video. Hopefully you guys can see it:

And no problems so far with the transmission CG
I asked Comptech if they thought I should run High Temp Auto Tranny Fluid and they said since I don't go to the track I should be fine. They took a TL to the track a couple months ago and did some testing.

good stuff!

Nice review. I wish I can finally break down and purchase one.

Check out how much the engine moves at the end of the video! I think ETD is a must.

Have you noticed a difference with the colder plugs?

rmpage

I don't see why it would. Ethanol has a relative octane rating of over 100 (RON + MON / 2) so it might actually help with detonation.

Tsx536

Thanks C Jizzle

Tsx536

Yeah it does move a lot. That's right after the engine hit the rev limiter. Would a engine torque damper increase the vibration during idle? What about when the a/c is on?

I haven't really noticed a difference but if I do I'll let you guys know. What's interesting is when I asked Comptech about that then they said the colder plugs are actually more important in the winter when the air is more dense.

waTSX

Nice write up, Kenny.

jmathew34

can someone take kenny's s/c dyno and superimpose a hondata dyno onto it? i'd like to see the differences in gains across the band...

anyone?

JTso

iTrader: (2)

Hondata and Kenny used different dynos so the graph comparison would be meaningless.

Tsx536

I don't think Comptech did a dyno of my car with Hondata before it went back to stock, but I'll ask them.


Edit: That's post 5,000 :gheywave:

Nice of you to restrain yourself from creating a "My S/C TSX dynoed at 5000HP" thread.

5000 posts wow, i can't imagine spending so much time on this site.

Nice trip report! Looks like the RT cat made you lose power.
Were you able to see the Comptech TL? Someone on the TL boards had the chance to drive it.
He mentioned that with VSA on, the car feels like stock due to serious traction issues with all that power.

jlukja

Tsx536

Haha...Yeah that damn RT cat.

No, I didn't get a chance to drive it. I was too busy with everything with my car. I should have asked though. Maybe next time! What I really want is a ride in one of the NSXs though
