New injectors

[Burning oil]

The fact that he is going to put your faulty injectors back into stock is enough to make me not want to buy from him.

X2 WTF?

 

[JMJNet]

At least you get the money back!!!

Well, I'm not counting on getting any shipping costs back, but the majority returned will be nice at this point.

That is why a set of those sits on a shelf in the barn, never to be installed or sold to anyone. I learned my lesson from here and got a set of bosch remans instead. Yet Walt will resell them and probably sleeps well having no conseince.

I hate to admit it, but I have a set of his so called marine injectors NIB, sitting in my garage too. I bought them when I go the 18:1 engine from Peninsular. I think I'll have my guy test them and maybe if need be have him rebuild them properly.

I also have a brand new IP and lines I bought from OFI when I got that engine. This will be a good time to install that too. Then, have the currant one on the motorhome remanned too.

I got some teds injectors I will sell for cost. I bought them for 200 or 220 off e-bay, and paid to have them pop tested, cnt remember the PSIs, but they were turbo spec, and withing a couple hundred PSI. (2000-2200 IIRC) if you would be more comfortable with them.

for a dream engine build though, I would personally find some german bosch new, or reputably rebuilt.

I have been talking to a guy I know who builds 6.5's and he said he can build me a set of injectors set to whatever pop I want. He recommends 3000-3300psi for chipped trucks. He says he has 20,000 on a set of 3300 pop injectors and it hasnt hurt the IP at all.

 

[matuva]

3000-3300 PSI? Looks a bit as a very high pop pressure?

 

[hookedup50]

Should be 2000 to 2300

 

[matuva]

yup, IIRC, stock is in a 2000-2300 psi range, and the Hi-pop ones around 2600psi.

 

[pacificdrumma]

He recommended 3300, thats what he runs in his built up trucks. He has a mechanically injected 6.5 with a pedestal center mount turbo, over 300hp to the wheels, and he runs 3300 on that truck. Nothing is set in stone, and I am still trying to learn about which psi is right for me.

 

[matuva]

Yup, I understand. What I say is that under such a pressure, I would not have faith in the standard nipples of the injector lines. Not sure either the nozzles will last what they should

What does Kennedy spec their high pops at?

IIRC 2250 is what he told me on the phone when I ordered mine. That is what I've always heard is "turbo spec". They do settle about 200psi though after you run them for a little while and they get "broke in".

The highest I have ever seen some set to is 2600 so when they settle they will be 2400

FYI

I received a check from ssd today for the injectors I returned to him, plus the shipping (one way).

I have the cast off, but now have a boot for a while longer. So, I haven't been able to get the doghouse cover off yet for diagnosis and pictures.

That kind of pop pressure would be pushing the rotor head right to the point of seizing at full fueling and 3,000+ RPM's. Not to mention it would retard your injection timing back a GOOD amount. The 2200 pop pressure is supposed to maintain in the 8,000-8,600 PSI range at the rotor head in the upper RPM's and higher fueling IIRC. So going to 3300 could easily push you past the recommended max range of roughly 11,000 PSI at the rotor head(and I believe it is just shy of 13,000 PSI that the rotor head will shear off or seize). These are DS pump specs if I remember them correctly(been quite awhile since I was up to speed on 6.5 stuff), but I don't think the DB pumps were much if any higher.

This should finish out the new injector thread

Here are some pix of the injector swap and some towing pix.
1. #8 injector from the top side
2. #8 and turbo from under
3. The turbo tail removed
4. #8 injector exposed
5. The Napa reman and the old injector
6. Husker 65 towing me to campsite
7. First tow from Lincoln to Des Moines
8. Hooking up to second tow
9. Home
10. Foot/leg before cast one week after injury
11. Red cast
12. Red cast decorated up for July 4th Blues Fest in Downtown Lincoln

I will start a new thread on the 6.5 carnage and bad luck events that went on this summer, as time permits. I've just got all the casts, boots and braces off. Now to play catch up before winter.

 

[3bals]

I see the pix got mixed up. I was having trouble uploading them too. The bottom 2 are out of sequence. The first one is the turbo from under and the other is a view of the injector and gp from under with the turbo tail removed.

I hope one of your winter projects is brewing up some more beer, Jody. That red pepper beer that you made and gave me a bottle of a couple of years back sure was tasty!
