A question for those that play with sticks

i currently have a diy 230cc hybrid injector kit sitting here. im running everything in my sig, would it be safe, as long as i watch my gauges, to put the kit in with stock nozzles to keep the flow down? would i see a gain in power? i would think the injection pressure would be higher but i dont think the cp would be too high for the stock hg's and bolts. i want to get some power out of this thing but until i get studs and a turbo(s) i dont want to over fuel it and pop a hg. what do you guys think? what will a stock obs nozzle put out?

Re: A question for those that play with sticks

I'm currently running 200cc Hybrids with 30% EH nozzles on them in my '97 truck. Its as stock as it was from the factory other than Air filter, Chip and the injectors (The Wheels and Kenwood don't really count).

Runs ok right now.

Re: A question for those that play with sticks

If you are running a SD turbo, just set the WG accordingly.

Re: A question for those that play with sticks

With stock nozzles that will be NO different than with the stock injectors. Nozzles determine injector "agressiveness" not capacity. They will not be a single bit different than your bone stock injectors until your programming calls for more fuel than your stock injectors could deliver.

Whether or not it stays together for you depends SOLELY on whomever you choose to tune it.

But the main thing is, with the stock nozzle, if you pull the chip it won't be "like" stock, or "close to stock" it will BE stock.

Hope that helps.

As much as I want to I try to drive it as hard as I can without smoking, i.e. rowing through the gears and roll into it until I see a little haze in the mirror and stop there.

Its VERY manage in lower setting obviously, but I can still stab it and get a decent cloud. Still managable in the hot setting, just slightly less. As for EGT's I don't know yet, I haven't invested in gauges. Data from the Scan tool shows ICP holding 2900+ psi at WOT cranked up on the factory 15 degree pump

Re: A question for those that play with sticks

charles, pw is the main ingredient in fueling, i understand that. from what you said the stock nozzle wont let any more fuel out even if the injector has a higher capacity, from that i get that even with stock injectrors, they are still not fully emptying all 90cc they should be good for?

Re: A question for those that play with sticks

If they were, then you wouldn't ever get power by adding a chip to an otherwise stock truck

So clearly if you pull the chip, you'll experience the same old truck you're used to because the injectors will not ever stroke out anymore fuel than stock. Or, in your "stock" setting, same goes.

The nozzle determines drivability. Not the capacity. If you took a stock AA, but put a 300% nozzle on it, it's going to be smoky and touchy even with no chip. Conversely, if you put a stock 7 hole nozzle on a 400cc injector it's not going to know anything has changed without the chip in. Because it will never be commanded to inject any more fuel than the stock injector did with that very same nozzle.

If you don't plan to make more than about 300rwhp, the stock nozzle wins hands down. If you want 400, it can do it, but you're sacrificing top end with all but the craziest injectors. It can do even more than 400, but you're really pushing things, and most trucks won't put that power down on stock nozzles.

Re: A question for those that play with sticks

so i guess i would be better off putting the 230's in and have the tuner pull some pw out to keep fuel flow down to say around 160-180cc's?

Re: A question for those that play with sticks

You can put nozzles on them if you want, just tune accordingly.

How well do you trust your tuner? That's really what it boils down to.
