No pics but here's the low down:

Today was the first day of Import Alliance 2008 at Nashville Super Speedway. Carma Performance was out there with their Dyno Dynamics mobile dyno. I thought "what the hell, I brought money to spend". When I went, not many people and no line. When I my car got on, suddenly there were a few cars in line and a TON of people around it. They prepped my car, asked some questions,gave me forms to sign and got to it.

The car:
1996 Honda Civic CX Hatchback

The Motor:
B16A2 from a 99 EM1 Civic Si
10X,XXX miles on the 9 year old motor
STOCK Internals
AEM Short Ram intake with a filter that's never been cleaned (about a year and a half on the car)
Exedy Stage 1 Racing Clutch
Clutch Masters Light weight flywheel (7lbs I believe)
STOCK Exhaust Manifold
Custom Muffler shop catback
A'PEXi World Sport II Muffler

Now, I was hoping to break 130 at least. I guessed 135WHP TOPS.

Run 1: 144WHP :shocked:
No friggin way. AWESOME. I broke 140WHP........

Run 2: 148WHP :shocked: :shocked: :shocked: :shocked: :shocked:

DAMN!!!!!!!!!!!!!!!!!

At that point, everyone started asking me what all mods I had, and I heard a lot of people say "woah" when they saw the 148. Apparently neither I nor anyone else expected it to do that well for what it is.

I've always heard 1 year = minus 1 HP at the crank. So that would have put it stock at 151HP at the crank. Add a coupla HP for the intake and exhaust. Then the power lost getting to the wheels, accounting for the flywheel, I just didn't expect near that much. I'm supposed to get an email with the dyno chart sometime (SUPPOSED TO, no guarantee they could read my hand writing).
 
Good numbers! congratulations, I really don't believe the - 1 hp every year in a honda motor! :woot:
 
what's crazy was all the uber badass cars at IA (which I'll be going to again tomorrow, 2 day event) and some how I get attention for having a beater hatch with a 148WHP. There were cars with 800HP and more. There were races too and full blown track cars were out there. Some crazy S2000's, one whoop ass Scion TC, 06+ 2DR and 4DR Civic Si's, an R35 GTR, Skylines, BMW M3's, Porsche's, you name it, it was there.
 
148whp is GREAT! your about 15whp over stock b16a's which usually dyno in at 130-135whp on a dynojet.

and for all the UK people thats 175BHP
 
I might wanna have my mechanic check the internals when he changes my timing belt to see if the valve train or anything else is not stock. I doubt an AEM Intake and Custom Catback with an A'PEXi WSII could produce that much extra power on an engine this old. I'm startin to think the engine was rebuilt at one point.

Also, today I went back to IA. At one point I participated in a rev exhibition. A lot of people got booed. A Miata at the very beginning, a Pink EJ8, and my friend's beat up CBR600RR with no muffler (hit a deer) got the biggest rounds of applause. I got mild applause and probably the best of the beaters (excluding my friend's bike). The dude "MC'ing" told me I was better than the other beaters that participated. And I accomplished that with a muffler designed to be quieter than most other straight through mufflers. The car in front of me was an EF with a can and he got booed.

ehm.. how do u exactly tell which model of B16a u have?

i mean; the engine stamping wont show b16a2 printed on it right? or does it??

mebbe i have the higher HP b16a?

i run on stock internals as well; jst some exhaust & intake mod; i m outputting around 160whp on my b16a :)

i m not trying to boast or anything like tat; n have a ecu management to help me tune this engine.

Click to expand...

apparently the Honda NSX C32 engine does not achieve its Max output until it reaches 160,000kms run in. Titanium internals...
 
I dont want to spoil the fun in here or anything but theres no point for you guys to compare figures unless its all done on the same dyno, location, day etc... Otherwise itd mislead ppls thoughts.

the most important thing is, if you have a base figure from your car on the same dyno. This will give proper comparisons.... Otherwise this kind of comparison conversation is useless.

I've been on 2 different dynos with my 9 and one registers around 15whp difference. no joke
 
The opinions on this may vary but from my personal experience the B series engines only get better with age is properly tuned and maintained.

100k kms is hardly a bad mileage for a b-series, we had a track car ( a CRX Vtec ) with around 400k kms doing great and still going very strong, mostly we changed oil and the regular maintenance. It never gave us any trouble which is impressive and comes to tell us about one of the things Honda is great at which is reliability.

Like jugbugz said dyno testing should be only a reference, specially if your updating your car, in order to compare figures and know the results you got with the new mods.

Dynos also have their own tuning procedures, and the results may vary from dyno to dyno, so its not a good way to compare with other figures from other dynos.
 
OK, I was finally told about how this dyno works. Pretty much, what it shows is what's hittin the wheels. It's not showing anywhere near as much under what I was initially told. Anywho:

I actually broke 100wtq if I'm reading this thing correctly.
 
OH, one minor detail I forgot to mention. I achieved this power on a 95 degree Fahrenheit day in amongst 2500 cars in the infield of a racetrack (practically all concrete and asphalt), with 20 or so cars running around the track with the sun bearing down all day. Yeah, it was probably actually 100-105 out there (38-41 Celsius I think) so I managed to get decent numbers with bad heat soak. I plan to go to Carma Performance sometime in the Fall when it's cooler and re Dyno it (and maybe with some more/different mods like a header, different intake and possibly a new ECU).
 
I got 144.9WHP (b16a2) on the dyno which was 172bhp! Which i was impressed with - all i have is I.H.E. mods!

Great numbers mate!!!
