who's injectors are these & what's there flow?

[john keskes]

bottom section is very dark green.. I can't get under the hood now.. car is under a cover and under 2 ft of snow but i am so curious to know now. i bought the car with these.

 

[john keskes]

i think i just answered my own question : 50 lb injectors made by: Del Phi

 

[Chuck Leeper]

Several flow rates for Delphi injs... Get a pt number off of them. Should be around the top of the black part of the inj...

And change your fuel pressure regulator. You need to have an adjustable for modern chips.

thanks but i'm gonna leave the car as is for now. No plans on racing . She idles great and the tuning seems to be fine according the scanmaster #'s.

That is not an item that you would have for just racing. I just assumed that you would have a modern chip in the car if you have 50lb injectors, since stock ones are more like 28. Most new chips call for at least 43 lbs for the regulator, which the stock one is not. But, like most things, I could be wrong. If it idles great you probably do not have the stock chip, anyway. If it is the stock chip then you would not believe the much better idle and performance gained with a replacement. Anyway, I would bet the last owner replaced the stock chip with the injectors. Come to think of it, maybe that regulator is not stock. Are the last three numbers on the regulator 233 or 237? 233 is stock. 237 is the upgraded Park Ave. regulator.

Steve, thanks for the info! this is the kind i'm looking for.. I have no clue what chip is in this car but i am 99% its not the original. Before the snow storm ( I'm out in eastern Long Island ) we just had ( We got slammed & i can't get into the car right now ) i looked at the chip & it has no markings on it. The Previous owner just told me that the car had a "thumb wheel" device for the chip that was in there but the car didn't run great. he put the "other " chip back in ( which is the current one in there ) and runs much better but can't tell me who's chip it is. That FPR is a stock 230 . I've read about the 237 that also came in the T T/A but again this is brand new & the car runs fine with it. I think in the spring when i can drive the car everyday, i will get the urge to make it a mid-high 12 second car.. I can't wait to get get the part #'s off the injectors to see what they really are! Also need to see what fuel pump I'm running.. He had the Tank replaced with OEM tank & most likely has the OEM Fuel pump. This way i can see what i need & don't need to spend extra moola

Also it is of your best interest to replace the factory hard plastic vac Lin to the fuel psi reg with a rubber vac line and wire tie the ends.

 

[john keskes]

Why is that ? does the plastic crack?

 

[turbo nasty]

Yes the age of the plastic and more importantly the job it does. So if your line cracks or blows off then you lose your pnuematic signal to your rising rate fuel psi reg.....that in turn causes the engine to go lean and train wreck ensues....Head gaskets blow...knock hammers rod bearings ...etc etc.

 

[john keskes]

Got it. thanks for that piece of advice!

It is exactly for this reason, running lean, that you want to make sure that your chip is burned for your specific injector, turbo combo. For this reason one of the first things that must be done is to upgrade the fuel pump. Along with that we usually add a "hot wire" to the fuel pump to run it at a higher voltage. When we upgrade the injectors we must get a chip burned for the new injectors. The thumb wheel chip was a very good chip but it is old technology. That chip probably didn't work well because he couldn't adjust fuel pressure to the level required for the chip. Your car may be running "fine" with the chip that is in there now, but it may be a time bomb. Just a little of "let's see what this can do" can cause you to run lean and go boom! A modern Turbo Tweak chip burned for those injectors along with the required adjustable regulator may just make you realize that the car was not really running "fine".

Another quick tip: If the car is very stock it may still have the little black filter on the end of the passenger valve cover that has a hose connected to the turbo. If this is the case you will want to remove the intercooler and clean it out. It could have a pint or more of oil inside of it. We usually replace this filter with an open element K&N filter.

 

[john keskes]

That's again for all the tips guys & yes my car does have the mini K&N breather on the passenger valve cover already

 

[jasjamz]

He is giving you very good advice on the fuel system upgrades. Adjustable regulator, hotwire kit, and a good pump. At least verify the fuel pressure with a non rail mounted gauge.

Thanks.. I'll be getting all over this once the weather starts getting better.. February can't end soon enough here in NY

February is finally over !! the weather was decent today so I uncovered the car and satisfied the curiosities that i mentioned above.. my car has the stock 233 FPR, at idle with vac line is shows about 30-31 lbs. The injectors are the 37# variety - Delphi 1709034 . I did a couple of runs on an empty stretch and she does pull well to around 14 psi but not strong enough to break the tires loose on a roll. I know the car does not have a Hot wire & don't know what fuel pump it has but i think my next step is to run a hood mount FP gauge so i can see what's it doing under full boost.. I also know that i'm not running a 160 'stat. Scanmast is showing me about 184F. I wanted to see what my recorded runs were on the Scanm. but i deleted when i switched the motor off ! : (..
