Just did a dyno on my '99 Si

[DarkCivicCoupe]

Just came back from a Dyno day at a club meet in Sydney.

I got to do 2 runs ... the first run I got 72 kw (96.6 HP) at the wheels, and on the second run I got 73.6 kw (98.7 HP) at the wheels.

I must admit ... the conditions were pretty average (above 50% humidity and the temp was around 27 degrees C (80.6 F)

What do you all think? Is this good / bad / average?

Bear in mind ... my car is stock ....

Anyway ... wanted to know what you all thought

Do you have a B16? if so thats hella low HP

 

[baby99si]

99 civic SI's come wiht 160 HP to the crank how did you lose 62 HP?

Yeah that's exactly what I was thinking. But on a sidenote, get a drop.

Dont know ... (it was running on high octane 98 fuel also) ... hmmm...

[DarkCivicCoupe]

oh guys ... bear in mind this is AT THE WHEELS not at the crank .... (read someone mention that so yeah) At the wheels are my measurements ...

what do you mean by get a drop?

 

[LatinEM2]

s**t man u got 98 Octane, we only get 91 and the humidity might affect a little butnot that much of a drop in HP

 

[baby99si]

He meant get a drop by lower your car and you should have 138 or 148 one of those two not sure but thats what you should have had to the wheels.

 

[DarkCivicCoupe]

nah man no way I woulda got 138 ... we had DC2R's pulling only 99's .... dunno ...

 

[LatinEM2]

WTF DC2R putting 99 HP, what is your measuring sytems?

I am savin up for volk racing rims, bridgestone S02's, and a decent set of coilovers to lower it 2 inches ... it'll all be done in one hit I'll post pics once done :p

again ... keep in mind that this is at the rubber not at the flywheel ...


but yeah I thought it was readin pretty low ...

I mean ... the factory rates my car at 158 hp at the flywheel.... what's that at the rubber do u reckon ...??

 

[LatinEM2]

Here the 99-00' Si is rated at 160Hp at the flywheel, you usually loose about 15% through the drivetrain so you should be putting to the ground around 138+HP

 

[DarkCivicCoupe]

hmmm ... ok ... so what could be wrong here??? any hints / ideas for me to investigate further??

(I heared that the dyno I was workin on was givin out low readouts ... putting that aside though ... could anything else be wrong??)

 

[baby99si]

I dont know man but i just looked at specs for 99 si's and they have dyno proof of 138 to the wheels so something is way off in your car or the place where you got it done.

 

[DarkCivicCoupe]

what would I ask my mechanic to check ...

I mean ... this may sound silly but is there a way to actually troubleshoot this problem

 

[DarkCivicCoupe]

I reckon it was the dyno place ... we had tons of DC2Rs pull mid 90's .. the highest was 99.

DC5Rs were pulling low 100s ... some modified ones were getting 110s ...

ALL those cars cant be full of ... I reckon it was the dyno ... what do u think?

 

[KoketsuCivicSi]

u should be getting at least 125hp to the wheels
