How much would some lazar cut delivery valves help out my truck with out upgrading my injectors. thanks

 

to my knowledge; not at all... you have to be able to flow enough fuel through the injectors for the delivery valves to be considered a restriction... stock dv's can flow a good bit... larger injectors and you amy need them. someone with abit more knowledge of the dv's should be by to help you out more.

 

You throttle response will get better, You'll gain a bit of power but the big increase will come with a set of injectors! Laser cuts will flow a TON of fuel. The laser cut DV's Should only be used in competition type uses WITH gauges. Now lots of folks run them Daily driving the truck, but it's alot of fuel. Depending on what pump you have, you might get the most benifit from 191's

 

what would be the biggest injectors recommended on a stock pump?

 

shoot, 191's and my 370's flow a TON of fuel..... i can't imagine what a set of LC's would do in my truck.... i had to back the fuel plate up ALOT to control the smoke.....

 

go with the 191 and a set of 40hp injectors

 

get your self a set of 181 dv's

 

Depending on what pump he has, He may already have 181's

 

where can you get 191s ..didnt they come in some of the pumps

 

We can offer them to you, All of the other vendors can offer them. Some pumps did have them.
