Civic Si Vortech (Need help)

Hello, I had a Civic Si 99 EBP with white rims, unfortunately i crashed it at low speeds but it still was a writeoff.

I just bought another Civic Si Black color 99. The car has the following modifications: 17 inch rims, big aem rotors, tokico illuminas, and in the engine it has a VQ-5 Vortech supercharger kit with 6.6 psi of pressure, i have dc headers and exhaust along with a apexi vafc.

Here is the question, the car pulls strong, but not as strong as i think it should, it pulls well from 6 thousand to 8 thousand rpm but its not a huge thrust of power, maybe cause its only 6 psi. I want to add the aftercooler and put a 10psi pulley, will this make a big difference? The car has 50,000 miles. the engine will last very long even with the 10 psi pulley? What modifications do u guys suggest to feel more torque lower in the powerband and to have more power overall?

Thanks for the help.

Hey MexSiR sorry for accident your car was looking real good last time you posted up. Post up the new car good luck!

10psi on that setup w/ an aftercooler (and professionally tuned i hope) will last for a while....that's only like 250whp so that would be very driveable and reliable. The only thing i stress a lot is tuning....make sure not to settle for something like the stock FMU....those are shit....get tuned on crome, hondata, or AEM....something good

I've been on 275whp+ for about 5 months and i had no problems...therefore i'm pushing my luck....:p

a kamikaze header with a 2.5 collector and 2.5 piping all the way back will set you up good.
