OK what's next!

I've been humbled today by a denali gmc was at a light came up next to me I didn't think about it Just ate with the family!untill the guy floored it on green he beat me off the line and I caught up by 40mph but then I couldn't pull him any more just stayed with him! Had that haha look on his face pissed me off! Anyway I guess I need something next take in mind IT MUST be able to tow without throwing the egt's thru the roof I'm there now but after that I guess I need a bit more! But what Injectors? Seems the dv's give the stockers plenty would they make a difference? OR???:smoke

EDM injectors burn cleaner, and make more power with lower EGT. Then it may still need a turbo.

Injectors would be good. Maybe a 2095 plug :shrug:

Delivery valves (especially LC's) give what I call dirty fuel. They smoke lots and make high EGTs but don't give much power.

You might need to upgrade that s300 to a 62

So I should use my stock Dv's "185" and put a set of injectors in?! What will that 2095 plug do?

then why do some use LC DVs if they dont produce any more power?

I'm no expert, and I don't have a lot of experience so take my opinion as just that, an opinion.

The more I learn about these trucks the less I believe delivery valves larger than 181's give much power. The definitely deliver more CC's of fuel, theres no doubt about it. But in reading about them I don't think they provide the fuel at the right time. I don't think the EGT's and smoke from them is worth any power gains they provide. They sure are fun though :smoke

DV's remove a predetermined volume of fuel from the line upon closing. This is designed to quickly drop the pressure in the injection line. This cleanly closes the needle in the nozzle and avoids bounce or reopening of the needle after injection is supposed to be finished.
By removing the shoulder and creating laser cuts, when the valve tries to snap shut it won't create a slightly lower pressure in the injection line and fuel may be pushed past the vale and either make a slow end to the injection. Like when you turn the garden hose off with a regular knob valve and the pressure slowly drops until there is none. Compared to using a 1/4 turn valve when you turn the water immediately stops in a instant. The inter-workings of the injectors help to eliminate some of this but I don't think its enough or bosch wouldn't have designed they delivery valves the way they did.

If you used an oversized dv's and holders I could definitely see how they would provide more fuel.

Again I'm still kind of a newby to this stuff and I'm still learning. If some one knows more, feel free to correct me, I'd love to get this figured out
