What about these injectors?

[Fnschlaud4620]

I have been in the injector market for some time now and I have found the injectors that I believe I am going to buy. I just wanted some input from the pros before I spend the doe!

Power Parts Engineering
Rated at 370+ hp with VE pump
5 hole .020 tips
145 deg spray pattern
400.00 exchange

Special secert stuff add 20.00 per stick

Well I ordered them today so I hope they work well. Anyone have any expirence with these guys?

[KTA]

Your post is contradictory, you said you wanted input, but then you say you already ordered them?? You can report back to us on how they work out, especially with dyno numbers. I hope they work good for you, the price is plenty cheap.

[Fnschlaud4620]

Yes my post is not correct, I am very impatient and I guess I need some grammer lessons.

I got the injectors on the way with the added work to what the guy said "body, pencil, and some type of filter" I do not know for sure. He was talking jargon to me.

I would have liked to gone bigger, but he said that being I was not into pulling he recomended not to or they would smoke a ton at idle. He said that these will haze a little but not as bad as the marine tips. He said I should be able to achieve around 400hp for the 520.00 I could not resist buying them that second. I am jumping into this head first. Checking out Swankmetel's twin turbo pics on TDR inspired me to build twins for mine. I still have to build my intercooler setup then I will need a VE pump genius to tune the pump. Is there any one interested?

[KTA]

You have a good twin turbo setup it looks like, one that is capable of providing enough air to go well into the 500+rwhp range, especially with the right exhaust housings on them.. Flow wise those injectors should be capable of easily running in the 700-800hp range, but I think they are awefully big tips for a VE. I at one time I had a set of 5x.025 for a pulling tuck application and they ran like crap and made terrible power for me. The VE isn't capable of generating as much pressure as a p7100 and subsequently the atommization suffers. I am anxious to here how these work out with your combo. I am glad to see someone else pushing past what POD's can provide.

[Fnschlaud4620]

You raise some very interesting questions about the tip size. I am going to call and double check tomorrow because the guy said that he "thought" they were .020.

I do not know if this information is revelent to injectors but figuring the area and number of holes of injector I have come up with some numbers.

AREA
Stock injector 6 hole x .009 = .000381
marine 370 5 hole x .012 = .000565
POD injector 4 hole x .014 = .000615
5 hole x .014 = .000769
5 hole x .016 = .00100
6 hole x .016 = .00120
5 hole x .020 = .00157
5 hole x .025 = .00245

Seems to me that 5 hole .016 are more like what I need from this data.

Would injectors with several, smaller holes (something like 8 x 0.012) have better atomization than ones with fewer, larger holes (like PODs) given the same area?

Injectors are a long way down the road for me (after college sometime), but I'd like to know what to look for

[KTA]

POD's are 4x.014, and yeah I would think something a little smaller might work better for you. As for the other question more holes is better to a point, if you get the fuel droplet to small it doesnt have enough mass to penetrate and move through the air in the combustion chamber and it burns too slowly, therby hurting power. Injectors are complicated and a hole lot of trial and error really.

[Fnschlaud4620]

I contacted Power Parts Engineering today and I was wrong again. I was getting 5 x.012 which they call their 370 injector. I believe I did not hear him correctly and I thought he said .020, oh well it is cleared up now. I told him I was thinking of going bigger hole size than that, he said I could upgrade to their 435hp injector which is 5 x .014 and he let me have them for the same price as the 370's 520.00 + shipping. This was as big as they wanted to go with my pump I asked about 5 x .016 and they said they would do it but they could not say they would work very well, I dont know. I left it in the hands of expirence and went with the 5 x .014 435hp. All I really wanted to have an edge over my cousins single turbo POD equipped truck. I think these will do.
It will probably be a while untill I have dyno numbers. KTA thanks Alot for all of your help.

Any update on thease?

I got the Injectors in the mail a few days ago. rated @ 435 hp with the VE They are 5 hole x .014 at 145 deg spray pattern, 7mm tips for a VE pump. They look really nice. I am not sure if I have 7mm head or a 9mm. It is a '91 non intercooled engine. PPE said if I need the adapters they could get them for me. I actually am glad they are 7mm so the can work on a newer head.

But I now have a decision to make. I recently picked up the housing, gear, lines, front cover and a 97 P7100 pump off a 97 dodge. That is in good running condition. I dont know if I should try the VE injectors or just try to sell them now for what I paid. I do not want to loose money on the deal. I also dont know if I want to go through the work of changing the pump. PPE said they could also reset the pressure in the injectors and make me up a set of custom lines.

I dont think I have the funds to do the P-pump conversion right now Cause I would want the bigger delivery valves and "Work" done to it.

Also I want to fire ring the head, But what Should I do? go gen 2 12v or gen 3 24v? Will a 24v Head fit on a 1 gen block? I know I have to change the pistons for that one. PPE said they have lines & injectors to do that too.

Then again I only have a 4L80e transmission.

any opinions?

Prime example of what I always preach. DECIDE WHAT YOUR END POWER GOALS ARE THEN BUILD TO IT!!! Do not continuously upgrade or you are just pissing money away. Save your money till you can build what it takes to satisfy you and then do it, you will be way better off financially. Once you build it then in 6months you cant decide you want more, or else it just starts all over again and basically everything you had was a waste or a compromise. Modifying is a slippery slope with no $$$ end unless you can excercise self control.

[TOMTOM]

Thats were i'am at. A YOUNG MAN ONCE TOLD ME YOU'LL ALWAYS WANT MORE THAN YOULL EVER GET!!!! WISEASS OR WISEMAN? The fact is YOU are the only one with the answer. Thank goodness we have the web and good guys on forums like this to help us. [b]

that is good advice.

KTA, i like your comments and advice... i am going to try to be one of the people who "push past POD's" however i am doing some mods in the meantime. my wife's truck will get the leftovers of what i can't use so i don't really consider it wasted money. actually bombing my truck has been a self supported and actually money making process overall but especially lately! have a few questions but i am going to throw them in a new thread now that i think of it.

[Fnschlaud4620]

Oh well, Its only money! I figure that if I loose a few hundred dollars It was the cost of alot of fun. I wasted more money on Disney World than I paid for these VE injectors. I Know I will have more fun with the injectors than I ever did at Disney. The Injectors are going in and I'll see what they can do.

I think the p-pump will be sitting in a box for a while.

Anyone sell custom ground fuel pins?
I would rather not grind mine my self, I think expirence is invaluable for this. I would be happy to return mine for a core. I just dont think it is worth 175.00 to buy a new one.

Thanks for ripping on me, Especially you KTA, LOL
