hi all what pressure should i see from a lpt v70 awd when given the berrys?

cheers rob

 

5-7 PSI is normal for stock boost on an LPT.

 

oops think i need a lower scale boost gauge then!
the on ei just got goes to 30 psi!!! hahahaha


rob

 

Your fine. You don't need to down grade.

I have an LPT and I have a 25 In Hg / 25 PSI gauge. But I have an ECU upgrade so I am pushing 15PSI right now.

 

s70 your pushing 15 psi with an lpt?

 

Yes and that is the highest you want to push on an LPT period.

 

so would it be poss to wind a stock turbo open to say 10-11 psi? with no other mods? and safely?
if not can i put a normal t5 turbo on my engine with no reliability issues? and what pressure would a stock t5 turbo give?

rob

 

1. You can run 15 PSI on your OEM turbo with no problems. Now if that turbo is going bad or is already in bad shape then yes there can be problems. 10-12 PSI is a good boost in pressure and a nice noticable difference from 5-7 PSI. And it is safe if you go with an ECU upgrade.

2. You can put a T5 turbo on your car. But it isn't going to boot anymore pressure then what yours is now. Because your ECU is controlling the boost pressure. But a T5 turbo can handle more pressure better then your LPT turbo can.

 

"Standard" ECU chip will be around 12 lbs and is very nice and verynoticable

 

sorry bud but what do you mean by standard ecu chip?

rob

 

He means the "standard" with respect to the tuning companies that actually have chips available for the Volvos. They are not really chips any more, but a soft loaded program, usually through the OBD port. Without this ECU tune, I'm reasonably positive the computer will cut out any additional boost you try to give it, such as with a boost controller (for anything newer than 1999.)
