Due to a somewhat humbling matchup with the wife's 98, my old 95 needs a bit more hp. I'm thinking a set of used 181s or better yet, 191 delivery valves.

So if anyone has a set of 191s (or 181s) stashed away, let me know.

Last of all, who's upgraded a 175hp pump with 181s or 191s with a setup near mine and what kind of results did you see. Both in power increase and egts.

Thanks RJR

 

Well, I can tell you what big dv's will do for a 160 pump......I can't remember what size dv's are stock in a 175 but I think the results should be similar.........The truck picked up huge bottom end power....turned it into a real tire burner!! .......For your application, 181's will definately be enough - you won't notice a difference with 191's if all you are running is a 215 injector.........The 215 hp motors from the factory were equipped with 181's.......she will be a little more smokey down low but it will be tunable.

 

i have 2 180 engines that have 181s in them supposedly stock if this ifo helps

 

In a lower HP situation such as yours I would not consider the 191's. I would find a set of 181's and if they do not do what you would like I would personally consider a bit larger injector. JMHO

 

191s..... Yea Boys.... Thats it, Lemme tell ya, a set of 370's 191's 4k gsk #10 Slid up and a 0 on the shelf..... Better have some big air is all i can say!
