Engine/Transmission (1994 - 1998) when are 191's necissary?

[NBowlin]

when do 191's become necissary?

at what point do 191's become a must, or do they?

 

[Jeff H]

Just for really high horse injectors.

It also depends on which pump you have. I don't think you really need them in the 215 pump.

Only on the small P-Pumps do they, at times, become a must.

How much hp you want? I have a 215 pump and 191s arent enough for me. I have custom delivery valves and i gained about 50 wheel hp, but it depends on a number of things.

I agree. If you want HP, you gotta get delivery valves, at least 191's. typically you want to add them ~400-450 wheel hp or so, or if you plan on a larger turbo you will want the fuel to spin it up.

thank you for your responce

i am planning on useing 370's, #10 plate, scotty 2, 3kgsk, i am going to talk to mr yardley about a turbo, and talk to eep about a cam. i am having to plan it all out and have parts ordered, so i can go on leave and help put it together. then have it shipped over to me so i have to try and get it right the first time.



thank you for your responses

191's are a very easy addition at a later time if you decide not to go with them now. I would say wait, that way you have a little "tinkering" around to do in the future to find a few more hidden HP.

NBolin:

If you are planning on a cam and a turbo from Kurt, why only 3,000 GSK get the 4,000 and have it over with. You won't regret it. And you will have a much better driving truck and you won't have to change and add the center spring later. Be sure to do all 12 valve springs.
