JC members suggested we should put this information in the V6 development and mod area to benefit all V6 ECOTEC owners. For full story see http://forums.justcommodores.com.au/showthread.php?t=42803
Here at Raptor we have just fitted some FIT 1.97:1 Ratio valve rockers to our ECOTEC as part of the upgrade path prior to supercharging. Read on for the results we measured!
As you can see (dyno chart) from the power AND torque curves the improvment is everywhere right through the range with a noticeable increase at the end of the power run. Car really pulls well for this small upgrade and we reckon there would have to be at least .2 of a second at the strip to be gained now, the car slightly taps the limiter in first gear now since the RPM flicks up damn quick!! :thumbsup: The stock air filter and intake system are all still in place, only 3 changes have been made, extractors, exhaust and finally the high lift rockers
For NA mods its nearly impossible to go past the 1.97 rockers and exhaust system combo in terms of bang for buck! We can't think of a more useful V6 upgrade anywhere.
STOCK POWER 114.6 RWKW
Power with FIT 1.97:1 rockers, extractors and HSV pipe 134.8 RWKW or 180 RWHP
Gain is 20.2 KW or 27 RWHP :dance:
The stock quartermile time was 15.65
The time after extractors and exhaust was 15.52
Time at track after rockers ....... will be revealed Sat the 11th Nov after next Test and tune, should be quite improved!!
Even from this point we would have to say HIGH LIFT rockers are a must for an NA ECOTEC if you want to experience a solid power gain.
