I've had quick search but most specs I've seen have 1000 peimry and 2000 secondry

I've orderd 4 x 2200cc injectors and both rails

I already have a walbro 450 in tank
People keep telling me this is a bad pump and to stick to 044 bosch

Planning to run 22 psi on pump gas
Turbo is a t70 turbonetics
After 450whp

Current set up is 850cc injectors all around

I was getting very high duty at 9k rpm
Was like 98%
Didn't like them hi numbers also the motec starts beeping at around 78% or somthing around there

 

2200 all around isn't necessary, 1000cc primary and 2000cc secondaries are suffcient

 

Is there not any benefit to being able to run low duty cycles and thus more precise injector timing?

 

You should get four of the new ID 1700's, probably the best injectors in that market right now.

 

I'm running a Power FC with (4) 2150cc High impedance injectors, Twin Bosch 044's in my street port 13b. I run E85 so I really needed the extra fuel and its plenty It made 601hp on the dyno last week. Drivability is very good too. On pump gas they may be overkill but that's what tuning is for.

 

Lol what duty is ur injectors at peak ?

I've got them now still not decided whether to put them all in or not
May also run e85 as you
What Afr u hit on e85 at that power ?

 

2200cc primary injectors on pump seems WAY overkill... I hope you like an overly rich idle.

450whp on pump can easily be had with an 850/1600cc setup.

 

we dont need all 4 matched.

1700cc 2ndarys is stupid and pointless when they are the same cost at 2000s.

further if 1700 can be used for idle without it being overly rich, then 2000s are that far off either.

personally if u can only run 4 injectors the 1300 prims and 2000 both from ID.
if u can run 6 then you have many more options.like stock primary or 1000 primary and then 4 x2000

point is you should make your 2ndarys as large as possible. they dont need to run at low fuel amounts, that's what the small primaries are for.

 

I think your missing the point. These may be the best injector on the market because of their size and compadibilty with all fuel types! These injectors will not corrode or rust where it is well documented that the 2000s are very sensitive and will need quite a of bit of maintenance though out its life.

 

Yes I'm aware of this, you're completely missing the point.

ID1700 secondaries are not stupid and pointless.

The ID1700 is better than the ID2000 at just about everything besides pure volume. It also is completely stainless steel internals like the ID1300 so it doesn't have any rusting issues if you let it sit too long with E85 in humid climates like the ID2000 does.

The ID1700 would do fine with idling in the primary position so why not have the extra overhead there vs. 1300's.

BTW I'm going to be running 6x ID1300 in my setup.

 

I'm going to try them see how bad and rich it runs if it's to bad I will run my 850s in the primrys

Again thanks for evrything advice and help will post back once I receive them and sort out the pipe work
Got me some fire extinguishers to
Never be to safe lol

 

Who's doing you mapping? The ability of the person tuning your car matters a TON...

 

I'll be doing it or trying to any way
And if I need help I hope this forum will have the answers

I've already broken an engine trying to squeeze power out of it lol apex seal exploded was at 18psi on stock seals
Timing at 10 degree ish at peak Afr 11.3 egt started to go into the 800deg
Few engine knock
All your felt was a wobble when it let go so I've gone for stronger apex seals goopy ones

After a housing and re porting I'm just waiting on my shaft and bits to come back from ballancing I'm ready to reassemble
And still awaiting injectors (orderd them when I put this post up)

 

And I thought I was over doing it with 1000cc's and 2000cc's combo for 450 RWHP lol

 

I feel like this is very open ended, I am running 4 2200cc injectors on my car but I am running E85 so I need the extra fuel.

This may have been covered but I'm on my phone and don't feel like rereading everything.

 

im running just two 2200cc ID injectors on pump, its awesome. secondary holes are blocked off, no more secondary transition problems, and cruises fine in closed loop 14.7AFR. idles around 11.5-12.0 at 1ms pw

 

i have 4x 2000cc but i also am on e85, my idles around 12.5=13.0
