TSX Dynos
#282
Yep! I got the file, unfortunately this new fandangled computer I bought for the shop doesn't have a floppy drive. I will have to upload it from home. I got to see some of your dyno's JT. Do you own stock in Intec?
BTW-You're still the reigning TSx champion
They have a K24 in a civic that pulls 220+hp

Here is a link to the Dyno Pic. I would post it, but it's huge and I can't resize it right now.

I think I have a pressure washer that's got more power than this car. JK! I can't wait to slap the next Acura salesman that tells me this thing pushes 205horsies.

5AT guys, did you do your pulls in 3rd or 4th gear? Final drive ratio in 3rd is almost exactly 1:1, so that's what we should be using. I used 4th on my last posted pull so it is assuredly inaccurate.

The Mustang derives final drive ratio by conflating roller RPM with crankshaft RPM so it all works out. There isn't any error with them, regardless of what gear you're in. Not sure how Dynojets work.

It's all done by the software. Being able to dynamically vary the load it puts on the wheels (the rollers use eddy current brakes rather than simple inertial resistance) makes for a very flexible platform. Also with a Mustang you can tune the engine under load, rather than having to adjust a setting, do a pull, adjust it again, etc.

I know the Mustang dyno can load the wheels during runs to simulate road condition. But I don't ever remember seeing any SAE corrected dyno output using a Mustang dyno. The auto manufactures and DynoJet use SAEJ1349 standard to measure outputs, which means the output of a car tested under one temperature condition is the same as testing the same car under a different condition by using SAE correction. By not using SAE correction, the output is for that particular day and condition and can not be used for proper comparison. Many people intentionally used non-corrected numbers to brag about outputs, but SAE numbers are more meaningful.

I finally found a dynojet to dyno my car. Is that slight dip and increase at 5,000 rpms normal for an hondatafied ECU?
2005 - 5AT with Comptech Header, Comptech Icebox, Random Cat, Hondata,
and stock exhaust.

Mine didn't show any sort of dip; torque at VTEC was perfectly flat. However the little corkscrew artifact at 6900 can be ignored - that's the torque converter unlocking in preparation for the next shift. Actual peak hp is probably 4-5 less.
#301
Yes. The cam angles on each side of the VTEC point are about 15 degrees apart. The cam takes time to rotate, so just before VTEC we rotate the cam into position needed for the high cam. This decreases power just before VTEC, but the result is a better powerband above VTEC, ie it is a compromise.
Looking at your torque curve I can tell you have good breathing and a low restriction exhaust by the way your torque jumps after VTEC. Your setup would support a lower VTEC point.

edelbrock is making manifold for 24 k with wicked throttle body get reflash they say

OK, that piqued my curiosity enough to warrant an email to edelbrock. Not that the above guy knew what he was talking about at all, but I hit their website and they have a section marked "New" for Honda/Acura.

time for an update...
that is my lastest dyno and here is all the data i have collected on my car over the last 3 years:
1/4 mile best time stock - 16.5s california speedway
1/4 mile best time full mods - 14.7s
1/8 mile best time full mods - 10.02s irwindale drag
mpg: 24 avg
mods:
04 mt w hondata
injen cai
comptech header
custom single exhaust
carbon fiber hood
hankook RS2
kosei k1 ts
buddy club N+ spec
comptech rear sway
ingalls camber
i tried really hard to take off as much weight as possible. For every part i replaced i weighed the stock and the new. so far i've calculated my car to be approx 3230lbs - 96lbs = 3134lbs w 207 whp dynapack

here is a resized dyno
when launching im still gentle with my car, so launches are only @ 2-3k rpm
hardly launching at all, but its just my stomach churns if i jolt my car violently.
i want to see if i can i drive it 100k + miles with all my mods + hondata.
I know my car is capable of faster times with a better launch.
also, am i the only one in the USA who sacrificed the super powerful dual exhaust look of our slow stock tsx and went w/ single exhaust for max performance?
i think dual exhausts on slow cars is a parody

I would be interested to see a single vs dual exahaust comparison, but I doubt it makes much difference like rmpage has mentioned. Unfortunately, we might never find out so all the speculations remain. However, if anyone is willing to send me a single exhaust for testing, I will cover the dyno fee.
#314
i think those aftermarket exhausts people get may be heavier than stock exhaust. They may actaully be going slower for the big dual exhaust look.
fyi: the stock dual exhaust weights in @ 61lbs.
also ne1 need stock intake, header, exhaust, springs and shocks, and sway bar pm me.

14.7s 1/4 mile.. impressive... I believe you have the fatest recorded time for a TSX 6MT.. The second fastest was 14.9s for a 6 speed.

well a single exhaust wont have any negative effects thats for sure. The exhaust Im still waiting on (j's racing) weighs about 5kg flat. That's a saving of over 15kg over stock.
