Hi people.
I have a question for anyone that are kind enough to answer me
I've dynoed my car and with 160wph only.
I know B18C5 with 160wph isn't that surprising, like few of u seen it. but I still do consider that as low.
what my mods are JDM ITR Header, free flow cat, 2.5 cat back, FPR @ 46, Chipped ECU with ITR stock program. etc just bot-on.
my concern is...would crappy clutch affect the result?
also I did a CP test. 1: 200+ 2:200+ 3:198 4:200
overall its not that bad
my question is...what else I can check to see is there anything wrong with the engine?

 

Ever consider the dyno reads low or the weather has an effect?

The relationship between rear wheel power and flywheel power isn’t linear, due to
all the variables. Tire temps, drum temperatures, gear oil temps, and engine temps,
cylinder head temps, tire pressures that change during testing, slippage that occurs
with inertial and load type dyno runs, are just a few factors that change so that even
making 10 runs with the same car, back-to-back, can produce slightly different
numbers.</TD></TR></TABLE>

 

yes, but on the same day i did my dyno, ppl with the same engine like mine put down much better output.so..there much be something wrong with my engine..any clue people?

 

clutch could affect the result....even tire pressure could as well.

You didn't mention what the ignition timing was set at, when your last valve adjustment was or if you had your sparkplugs/cap and rotor replaced.....how about fuel filter?

 

I vote ECU.

Did you have a wideband sniffer during the dyno pull(s)?

A clutch can cause low numbers if it is slipping. However, you will know if your clutch is slipping.
