he351cw install, new injectors

[projectworkstock]

hi everyone, just joined in today, i own a 91 non ic 4x4 with 280000 miles with a 727 auto that has been upgraded with a low stall converter and a valvebody deep trans pan and aftermarket trans cooler, bought a he351cw today and i am looking for 400plus hp and was wondering what would be a good injector, no towing, just setting up for pulling and a fun truck, installing a water to air cooler and have boost pyro and trans guages, looking at a set of 5x14's, 366 spring, denny t pin, pump maxed, with a raptor 150lp, any suggestions on injectors?? are 6x16s too big for me?

I know the 6x16s are too much for the he351 with a maxed pump. I've got a set in my '93 with the stock h1c (twins are in the garage waiting on some time to install-to many other things breaking here lately). You've got to drive it very very easy so you dont kill the people behind you or melt it down. I know the he351 is a better turbo than the h1c, but you would need at least a 62mm s300 of some sort to make the most of them. The 5x14s would probably do much better or check on a set of pods to stay on the cheap side.

wouldn't the 5x14s give better MPG over pods ? --- aren't pods 4x16s so they do not burn the fuel as efishent

I'm new to this so I realy to not know

wile reading I see every one upgrade the fuel furst --- but just makes heat

wouldn't be better to upgrade the air "turbo" side of the motor furst ? than add fuel whin EGT's cool off

[oldestof11]

BC, its a catch 22... Not enough air equals a lot of smoke and piston melting temps. Not enough injectors mean turbo surge, bark, high EGT's from not putting it in its map, laggy spool up...

There you have it...

well i was thinking about running the 6x16s with a detuned pump and i only went with the he351 because it was 100 bucks and it is so close to the s300 setup which means easy upgrading in the future without modifing my setup, but the exhaust housing on the 351 is tight and 5x14s will make wicked power from what ive heard so maybe they would work good with the turbo and the intercooler,water meth setup, and a quickspool cam, and a port and polish job, just considered 6x16s due to the fact that i was going to upgrade to an s300 and a 14mm h/r in the future, just planning ahead.

If you don't mind haze and lots of smoke then go with the 6x16's.

do you think they will work alright if i turn the pump down or am i on the verge of melting the pistons if i go with the 6x16s with the he351

I run 300 hp with mine and I have a H1C with a 16 cm hot side and a 60mm gds on the cold side. Its super hot if I hold it but is drivable. I have 4 more turns left on the fuel screw. I am going to upgrade to a S300 62/65/14 soon and also upgrade to a 4 inch exhaust ( to match the turbo ). I like the power I have but wish I could actually use it. I am in hopes with a good turbo/ exhaust/ intake set up it will cool me enough to be able to get after it.

-with all of this being said, what would you all recomend for an injector that will get me over 400 hp on fuel, im not worried about haze or hard smoke, the 351 should light pretty fast due to the small hot side and clear up alot of fuel, but since this is my first 12 valve and coming from an 05 and 07 commonrail i dont know a whole lot, just wanting a good injector i wont have to change when switching to a s300

If you want the big sticks in the end get them first and adjust your fuel screw to the turbo you have. You can have as little as 180 horses all the way to 500 plus with a set of 6x16's. Like I said before the 16's run great, just hazzy.

how would these do if i hooked to the sled, to hot and dangerous, or hot but nothing to worry if i dont hold it there all the time

People say not to worry about temps for the short time a truck pull goes on. Again you can control the temp with fuel settings and your foot. There are guys here that get hotter then me. I don't let mine get more then 1500 for more then a couple seconds.

i want to say thanks for all the information and i am thinking about getting a set of 6x16s from dieselautopower, they have great prices, are they good or has anyone run their injectors

I think the reason everyone adds fuel before they add air is because you can still drive an over fueled truck. Right foot controls the smoke and heat (within reason). Put way too much turbo on it and you cant stay on top of it no matter what you do. Even though my '93 has more fuel than the H1C could ever clean up, I can drive it just fine if I try. I just have to ease into the fuel and lift before she gets too hot. I would never try to tow anything more than my lawnmower with my current setup, but if I wanted to tow heavy I would not have put the big injectors in until I had the air to match anyway.

Hey Richie-would timing help or hurt the haze? Mine don't haze anywhere near as bad as yours, but I have mine timed to the head right now.

It would help or at least should. I run stock timing in the 93 for a couple of reasons. First I love the low end power this truck has. If I advance the timing I will loose some. The truck lights the turbo real fast. Thats kind of important when you have to shift a stick. 2nd I have a stock head gasket and I am pushing 45 psi of boost. Advancing the timing will add to the cylinder pressure and sure as hell would pop it. My only complaint is the haze. It runs and goes real nice.
