i got a zc dohc, intake(ebay), headers (chikara) exhaust (2 1/4) custom. pg7 from the integra (automatic ecu) heard it doesn't make a diffrence. act clutch which i dont think matters on the dyno machine. denso iridiums. gutted catalytic converter. hot day in daytona tuner bash. on 87 octane. ive also kept track of my mileage and ive put 19,000 since it came in.

first time
results were 119.4 hp
106.8 lb/ft

second time
119.6 hp
107.3 lb/ft

kinda dissapointed any one got any suggestions
still running on the stock summitomo plug wires that came with the motor. does it make a diffrence.

 

advance the ignition timing to 18 degress, slap some 93 octane and try again.

 

im not shure how to advance it by 18 degrees i need a how to please.

 

first, get a timing light..... ahh better yet just do a search on here for ignition timing. Also check out http://www.thezcr.com

87 octane Those numbers aren't bad at all, what are you disappointed in? That's strong for a motor that is only in the 130's at the crank stock.
