| Red 1993 Volvo 940 Turbo |
I have an 1993 Volvo 940 Turbo and I have already installed ipd’s
performance camshaft, and that made a little difference but I’m looking
for a little bit more horsepower and boost. I’m trying to get 15 psi.
I’m at about 10psi. What should I do to make my Volvo 940 turbo faster?
Answer: Well. IPD also offers an adjustable cam cog
advancing cam timing helps low end torque retarding moves power band to
the upper rpm’s..
There is a perfect power 6 performance tuner available that will allow you to “tune” to the limit of your current modifications and will be able to handle future mods.
The exhaust is rather restrictive in stock form on these cars and there is the possibility of a partly clogged converter on a car this old. Performance converters are available [suggest JEG's as a source] and 2 1/2 inch pipe from the turbo flange back will probably be sufficient.
You may want to consider nitrous [wet system].
Spraying a large quantity of washer solvent across the inter cooler fins [drilled aluminum tubing from a lawn chair works well] will drop air temperature dramatically, increasing air density.
Use a large wash solvent tank and a high volume/pressure pump from a car with headlamp washers[junkyard] note properly designed you will go through this fluid quickly, so plain old water is ok too.
While your stock turbo can push a little more flow with a modified waste gate actuator a larger turbo should be considered as money allows [this will get you into the 15 psi range] note at this point you will likely need studs to replace the head bolts to keep from killing the head gasket every time you launch the car.
