Advice on 009 injectors PLEASE!

[DR. EVIL]

What is the approximate limit on horsepower with the 009 injectors?

What is about the best FP to run with these injectors?
I think mine is just a little over 45psi line off right now...

Would I be alright using a turbo that can support more horsepower than the injectors are limited to if I don't turn the boost up to the limits? In other words, does it really matter what turbo you use as long as you run it within the limits of your injectors?

I'm thinking of using a TA-53 thats good up to about 600hp, which I'm assuming is much more than 009s will handle. I have the stall to handle the turbo. Shouldn't I just be able to get the same power as before on lower boost levels?

Sorry for all the questions.... just curious I guess

It is ideal to have more fuel than turbo. Scan-Tool? Yes, bigger turbo with less boost but 009's run out in the mid to low 11's or 425-500 HP range. Most I witnessed with 009's run out in the 11.4 range. A friend of mine went 11.30's on 009's with 50 PSI static FP. He's done!

I have access to a Turbo-Link to check on things.

I really only have 2 choices on a new turbo since mine died... go smaller with a TA-49 or go bigger with the TA-53 (doesn't have the same exhaust wheel as the 51 or 52)
I think I'll go bigger because I can always sell my 009's down the road and get some 50's and get my extender chip redone for 50's..... good idea? no.... yes?

With that converter I would at least go to a 54. If you plan on hogging out the heads down the road, and you plan on stepping up over time, I'd look at a 63,64 or a 45.

Well, I have to keep in mind the fact that I liked how the spool was with the 51 at 21psi on some 100 octane gas.... thats the typical street tune for me. Thats pretty much what I'm running if not at the track. I want to have fun on the street from light to light

Head work and cam are both a distinct possiblilty.... but thats WAY down the road.
First I want to work with what I have, the 009 injectors. I don't really see myself going bigger than the MSD 50's after that because I don't want a new computer and what-not. Actually before I go with injectors, I'll be getting a V4 this winter (if I can get it shipped before winters over )

So if I go bigger than a TA-53, it can't be more than 50's can handle, and I still want the stock appearing TA if possible.... and hopefully in the price range of the original TA-51 I bought....
Does that help some?

Yea but why not get a well built turbo like a Craig 60 or 61. Or do you really like the quality of the PTE turbos

I have 009s in my GN and 50s in my T. Both a good injectors.

009s will support 42.5 X 6 X 2 = 510 HP

50s will support 50 X 6 X 2 = 600 HP

Both are nominal, based on 0.5 BSFC, which is either conservative, or right on, depending on your view of the fueling requirements of turbo cars, and where you like to run on injector duty cycle.

009s have gone into the 10s on rare occasions, but I don't think anybody would advocate that as a goal.

My advice is, if you have 009s now, why change anything - it's sort of "free" to leave it alone, isn't it? Give them a try and see how you like them. Just keep in mind that should you move up on air flow (i.e. heads) you may get to the point where you need more fuel.

We have a bigger is better fetish on this board. I'll bet in a year everybody on this board will be running 160s and T-100s, never mind that most guys will still be in the 12s.

Bottom line - the 009s will support a damn fast car...

I thought that was well put, im running 009s also. The only thing i noticed is around town drivabiltiy. From a dead stop and then giving it a little gas, the car hesitates for a split second. And letting off the gas while cruising, sometimes feels like the car hesitates also and then grabs again real fast. Other than that, they seem to spray fuel pretty damn good.

Well, I hear about the 51 and 52 exhaust seals on occasion.... but nothing about the 53 or 54..... fact of the matter is, I got a turbo that blew a seal, and I'm going to see what Precision will do to make things right.... I don't give up on a company until they give me reason to do so. I'll let everyone know how it goes next week when they're back from SEMA and deal with my turbo situation.

strikeeagle - you're right about "bigger is better" not always the way to go..... I have one hotwired Walbro 340 and a stock ECM.... I don't want to have to go throwing another inline pump in and getting a beefed up ECM just to use some 55#+ injectors.....

From what I've been reading, looks like a turbo supporting 570-580hp is about the most you could push with a set of 009 injectors.

A turbo supporting 600-615hp seems to be about the most you'd want to max out with 50# injectors....

So if I'm changing turbos regardless.... why not step up and only push power as far as the injectors can go and not the turbo? If it gets too "tame" for my blood by then... 50's easy to come by
But what should I get, a TA-53 or TA-54? Same price, about 15hp difference.

The 54 has some lag. If your not going to step up, I'd go with the 53. I know a guy who has a 4000lb GN (big stereo) and he's running 11.0 with a 52.

 

[DR. EVIL]

I'm all about the fast spooling, as long as my car wasn't running rich.... I could go from WOT from idle and hit 21psi by 3900rpms or so..... will I notice much difference in spool on a 53?

with the race wheels I have for next season, my car will be about 3300lbs or so that will be the only weight reduction done.... I love having a hardtop, with no factory options

 

[BLACK6PACK]

I went from a stocker (instant tire spin) to the 54. While the 54 spools a little slower, its not bad at all. I'm at full boost within a second or two. Its pretty nice that it doesn't come on all at once and fry the tires. Once I get up to 18-19 mph it the nittos start slipping, it hits second and continues to slip for a second or two, at around 55 the tires start to slip and slide again. After that I can loosen my grip on the wheel a little bit. I have a small cam, but the heads were worked a little, so I'm sure it helps.

 

[DR. EVIL]

so when am I going for a ride again??

I think the 53 sounds best for working with my 009's and someday some 50's.....
