Hey guys, I need to purchase some 1000cc injectors for my setup soon I'm looking between the PTE injectors and the RC Engineering injectors. I'm wondering what ones you've purchased and what your feelings are on them. I there are any other brands PLEASE let me know about them. Thanks in advance.

check out yawpower.com

they sell a true 1000cc high impedence injector. They also come with true data like dead times etc.

 

I don't know the brand, but I bought mine from Kgparts. I'm running them in parallel with 1680's on the secondary and they work great.

 

Bosch, with FJO injector controller, their awesome.

 

kgparts

 

thats what i got, full data sheep and flow chart with every injector and at a killer price.

 

I use RC injectors for a little over 4 years now, i would recommend them.

 

I got mine from KGparts also. You CANNOT beat the price thats he sells them at. I'm sure if you asked you could probably get flow charts for them.

 

What's Keith selling? I'm assuming they're Rochesters?

 

I bought Rochesters from Keith, they work great and are very cost effective.

 

kgparts here w/ fjo controller used for primaries. If I was buying again I would think about the ones Glen sells (yawpower)..

 

So why would you do it over again? Any problems with the ones your running now?

 

yes, rochester

also have 1200cc Lucas

 

I second the lucas 1200 disc injectors. I do have an approximated lag time map for these but it would be nice to get one from a reseller. Keith do you have a map for these?

 

Yawn Power is the way to go. I have them for my engine... 6# 100cc and 6# 720cc

 

No real issues but I was told by keith they have a shitty spray pattern, more of a hose opening and closing compared to a finer spray patter.

The Yawpowers seem like a well designed injector. I also like the shape of them. The 1000's I run (believe rochester's) are short and fat. The have a hard time seating and not hitting the iron= leaks. Now I would be interested in the 1200's keith now sells..

 

How are the design of the RC Engineering injectors? I like how the 1680cc injectors are nice and slim. My Siemens Deka 850's are pretty fat...

 

that motor looks so pretty....

 

I am uploading a video to youtube as I type. I will post it once it is up.
It is a little hard to tell in the video because of the glare I was getting from the lighting behind the flow tubes.



Ok, I believe this is the link even though the video is not showing being processed in my account: http://www.youtube.com/watch?v=i-MjDsXgQro

Injectors from left to right
Far left = Siemens 850cc
2nd from Left = Rochester 1000cc
3rd from Left = Lucas 1200cc (This is what people call an "RC" Injector... thier 1000cc's have same spray pattern
Far Right = Bosch 1680cc

Hope that helps.

 

I can't tell from the video but which injectors had the best pattern and which ones kept a good pattern at low injector openings?

 

marren injection 1000 cc rochy multech types
- all individually blueprint flow matched

drop in ready to fit with dual 11mm top
- and the universal base rubber
( which i have yet to have had any issue in fitting, unlike the later bosch O ring base type )

these arent pintle injectors, more like a plug disk
( different from the RC type disk )
and are a good compromise of response and flow, with excellent pattern

- i have seen superior idle , response and economy on feedback ECU's over old 550's !!

its important to be sure your multechs are flow matched
- as this is there biggest concern
and marren do it for you

 

Thanks for the video Keith. The Lucas injectors IMO spray like a hose. I love the pattern of the Bosch 1680's it's very broad and is the best candidate to atomize. I would honestly rate them (best to worst) as Bosch, Rochester, Siemens, and lastly the Lucas. Have you flowed any of the PTE's or RC 1000cc injectors yet? I'm really looking toward the RC's or the Rochesters at this point...

 

Just saw your one video of some RC 1000cc injectors. Their pattern is pretty non existent. I'll be calling you tomorrow to settle my previous invoice and to make a new on concerning these Rochesters . You better be by the phone.

 

we match them also.
If not mistaken, Marren gives you the option to have them flow matched or not. matched set from them costs additional $
You are correct though... at one point (not sure what it is now) these injectors had an allowable variance of 10% at the factory

 

That is a good, but tricky question. Fuel pressure alters this more so on the Lucas (what people call "RC") and the Rochester (what people call "PTE's")...
