ok i searched old and new archives, and still nothing im looking for. Heres my problem, boost controller is set to 10psi, stock spring on the WG is 4psi. Soo every gear around 4-4500 rpm by boost drops from 10 psi, to the stock spring BAR. I know the turbo isnt running out of breathe cuz it only get full boost around 3500

setup is b18c, t3, tial 35mm WG, open dp

 

almost every straight t3 is too small for dohc's. im guessing you are using a .48/.42 t3, which in that case it makes sense because up high almost every t3 runs out of breath

 

yes its a 48/42 but dont you think 4500rpm is kinda low for the boost to start dropping? it gets full boost around 3500

 

its a very small t3... thats whats gonna happen, right avter the vtec crossover point its gonna die. a bigger turbo will solve your boost drop problem

 

vtec is set at 6k right now

 

well thats way too highm and trust me. that turbo is too small for your motor and that pressure ratio

 

shift at 4800 and you will be a happy person that will prosper and find joy in many things in life...except turbo hondas. And put your vtec back to stock.

 

rofl.

not to mention the fact that your open downpipe isnt helping

 

so its just the turbo huh? im not doubting you i just think 4500 rpm is kinda low for a t3 to run outta breath

 

its the turbo.
