Why lost power on 4th gear. (20V)

[EG9]

My car seem to be slower especially when approaching rev limit in 3rd and 4th gear.
Even lost to stock 20V blacktop engine when approaching turn 1 and turn 4 in SIC.

I suspect it's adjustable cam pulley setting. I have reset the adjustable cam pulley but haven't try it yet.

Previous setting: intake:retard 4 degree/ Exhaust: advance 4 degree.
Current Setting: intake:retard 4 degree/ Exhaust: advance 8 degree.

Do u guy have any opinion on this setting or the problem may cause by other stuff?

chu it could be a lot of factors but actually u know it very well too that there's no two way about it,its either u want it low end or high end( can't have the power all the way from 3000 to 8000rpm rite ) like my cam setting is both advance coz i desire power band from 4000 to 7000rpm its response out from corner that i want especially if u frequent track day a lot but anyway y dun u start by telling us what have u mod to ur car so far so can analyse from there........cheers

I knew it, but try to minimize the power lost. Current setting is more suitable for short course, fast respond and fast gear change. Anyway will change the Cam setting tomorrow. hehe.....
You custome paper still with me. When are you going to collect it?

 

[7500RPM]

chu, i think its time you advance to a 2.0 liter car now..

Just "HOPE" only....hhahahahahahha

 

[QiW]

for hopes like that ... there will be more $$$ required ... huahahahahaahahaa .. :p

 

[chinozie]

maybe too light i think...
TRD flywheel how many kg???

 

[EG9]

Manage to gain back the power lost after try various of adjustable cam pulley setting.
the power seem to come in at 5500RPM and peak at 8000RPM now (Got abit of Vtec feel....like B16A engine). At the same time never lose too much of low end power as well. But still have to try in in SIC.
