Throttle Body 850

posted by  someone claiming to be Edwin on  Tue Mar 22 09:58 CST 2011 [RELATED]

I removed the throttle body from my 93 850 last night and cleaned it up. Has anyone here ever tried to replace the plate inside (with the plastic insert) with a plate from a 960 throttle body (no plastic insert). There is a write up on Matthews Volvo Site about the 960 plate will increase air flow and better response. Anyone have any thoughts on this. I have to think that the engineers at Volvo put that plastic insert in there for a reason and I doubt we are smarter than them!!!

Thanks

    Did it on my '96 N/A 855.

    When you first make the mod, you have the sense that the car is 'peppier,' but I think that is just wishful thinking.

    I've concluded that there has not been a change.

    I think this is the same kind of improvement that people think they get when the burn 89 versus 87 octane.

    #1 Plastic is cheaper than brass.

    #2 The 960 is a 6 cyl and needs more air

    #3 Your car is 18 years old, it goes fast enough

    I have done this on both my 850 and s70 NA's. improvement over stock, sounds a bit better, and I ran an airflow test, the engine does get a bit more air. I noticed a small economy improvement as well, though most people suggest it will decrease.
