5psi, Then 7psi Then 10psi....after Exhaust

[tezflow]

Hows it goin boys, i got my exhaust fitted yesterday 3inch turbo back, thats the only mod the cars got. When i drive it in the low revs it shows up around 5 or 6 psi then it goes up slowly till arround 7 or 8 then at pretty much exactly 5000rpm it goes straight to 10psi and stays till redline.

What my question is with a bleedvalve will that enable the car to be boost at 10psi right from the begining say 2500 (or whenever boost kicks in on the rb25's)

i just wanna make sure it will b4 i buy one, becoz a mate of mine reckons if its boosting to 10 psi now theres no point? Thanks.

yea your m8s correct.. u'll probably gain a more constant 10psi thru the rev range .. but u could invest ina r32 rb20 turbo actuator instead...... either way its naturally gaining boost as u remove restriction with the exhaust.

leave it for now .. save for a front mount.. then see where your boost sits when u fit that..

reading through my original post i think it may be unclear exactly what im asking, what id like to know if anyone can help me is will a bleed valve set to 10psi mean that the car will go stright to 10 psi as soon as it hits boost, as opposed to what happens now..which is a gradual climb (7psi up until around 5000rpm) to 10 psi high in the rev range? Thanks guys.

YOu will need to the do boost mod, the R33s have a boost lock until 5,000rpm.

cant remember exactly

there is a thread in here on how to get high boost setting through out the rev rang, pls search

just ground the solenoid so its constantly on. that bypasses the 2 stage boost that the ecu has. dunno if it will burn out the solenoid cause its always on. or you could just purchase one of those nifty mech boost controlers on the forum for $35ish and just set it to 10.

Yea forget the bleed valve and just use the hiogh boost mod with the standard actuator. $2 for the wire,. $3 for the switch. Dash mount and switch it to 10PSI at the flick of the switch.

I have an R32 actuator if you need one, otherwise the solanoid grounding will work well.

You said RB25 so I'll assume you have an R33.

Ground the solenoid and you'll get the instant 10psi as mentioned above. Also, when I picked my car up after a ton of work to it they left the bleed valve closed.

What this resulted in was a gradual increase in boost as the revs raised until it stopped at about 14psi. Opening the bleed valve up I was able to attain a much faster boost increase up to 15psi so as far as my personal experience goes, if after the solenoid mod your boost still rises slowly, try a bleed valve. They're cheap as chips anyway and you'll want one eventually.
