Has any shop/any individuals explored which one is actually the limit? I've seen at least a post or two suggesting that the lt1 injectors really aren't the issue, but the pump is. It would make sense that the pump is solely the limit, as an increased fuel lobe will take the fuel system noticeably further. (Low pressure issues assuming to be fixed).

Any comments, thoughts?

The limits of the LT1 engine are all very closely intertwined around whp. GM developed this engine to make hp and when you exceed that you run into multiple problems.

1. Fuel - you oversimplify with the LT4 pump and injectors. The car has both a low pressure side fuel system (electric in-tank pump) and a high pressure (mechanical) pump system. The biggest power boost can be gained by upgrading the low side pump. Not a lot of discussion about this because it is easy. Any of the pump upgrades from gen5 port injected cars can be used to supplement the low side.

High side upgrades are the main limiting factor in these engines. It is really hard to get the amount of fuel required to make big power through a tiny direct injector in a fraction of a second. High side upgrades currently can be done with a cam (increased lobe size gives more pump from mechanical pump), pump upgrade, or injector upgrade. Because the car uses direct injection these options are very limited. To this day very few aftermarket parts exist that are better than the stock GM parts and those that do exist are very expensive. Lingenfelter sells a hp pump and injector set for $ and that is as far as I know the only direct injection system than can dyno hp period. No other systems can touch this power level stand alone. The GM stock LT4 pump and injectors will give you around hp max and it is really best to run them as a set. The injectors are designed to run a certain fuel pressure. The LT1 pump and injectors were developed along side each other and so were the LT4 parts. You can run the LT4 injectors on the LT1 pump but they are not as efficient and same with the LT4 pump with LT1 injectors.

Perhaps the easiest way to overcome this direct injection fuel restriction is to add a port injection system on top of the direct system. This is exactly what GM did to get the power they wanted from the new ZR1 corvette engine. Many builders have done this to make big power builds but so far the factory computer does not support this and the aftermarket is a cluster of not well tested products. There is no doubt in my mind this is the direction we are heading to beat the limits of direct injection but the tech is still relatively new.

2. Compression - The stock LT1 is to 1 compression. Boost has a multiplication effect on the compression ratio of an engine and when you add a forced induction system you are very limited in the boost you can give the engine before the fuel is so compressed you get detonation. If you run alcohol this not an issue but most of the fuel sold in the USA is less than 10% alcohol. In reality that means unless you are making specialty purchases of fuel like E85 or race gas the LT1 engine is only going to safely make about whp on a tune where you could drive the car across the country and buy gas at the pump.

3. Piston and ring design - the LT1 was not designed to run boost and many, many people that have boosted the LT1 engine over whp have experienced an engine failure related to pistons, rings or even rods. To be honest the previous GM LS pistons and rings were better able to handle boost than these new LT1 engines. The stock LT1 engine really needs a piston and ring upgrade if you plan to take the engine over whp and run it hard.

In my opinion the LT1 is about a whp max engine without major upgrades. The LT4 is about a whp engine without major upgrades because GM adjusted the compression ratio and piston and ring problems. So, not just the LT1 injectors or mechanical pump but a cluster of limitations.

    lt1 fuel injectors

    i was tols to use 30lbs injectors with the le2 package will the stock fuel pump and regulator work and when i look at the pcmforless application for tune it says to use stock fuel pressure which is 42 right dose anyone have a link to injector and pressure table and im also confused i can inqure a nitrous kit for dirt can they tune it for a shot max and not affect driveabilty i proably will only use it a few times and i dont want the car to run extremely rich were it will be hard starting

    I am going to be using the stock fuel pump to get it running and then switch out to a ractronix fuel pump kit and reuse a stock fuel pressure regulator. I have a bottom end with LE2 heads. The less stuff you change at the same time you do a head and cam or entire engine swap, the less you have to question. They can tune it for NOS but I would do that down the road on a dyno tune after you break it in and sort out all the bugs but thats just me.

    I have 30lb injectors on my car with LE2 heads. You don't need a new fuel pressure regulator. Your tuner will dial in the fuel pressure, but the pump really needs to be changed. Run your engine lean one time and you can say goodbye to it.

    Some good and not so good in there but what bottom end are you going to be running? Stock bottom end with the LE2 and one of his custom cams will get you very close but the compression has to be some what high.
    I looked at the Trickflow 's with the 54 or 56 cc chambers and they made right around or so at the wheels but that was thier cam grind and I don't remember what it was.
    Edelbrock: People say don't bother.
    LT4 you can do it but having the lt1 heads worked by Lloyd or advanced is going to make them flow better than a stock lt4 head or edelbrock lt4 head. not to mention you have to buy the lt4 intake.
    Advanced induction can do any head you want and make power out of them cuz they flow them like what Lloyd does, BUT be ready to spend a bit more with them. I got a quote from them for a set of trick flows and the entire top end was going to be just under 5K smackaroos. It would be realy nice and done right but I just did not have that kind of a motor in mind.
    Trickflow heads you better see if you can find them right now. Summit ran out of the 's and said they have no clue when trickflow would be running that head in production again. the 's are really ment for blower and NOS apps unless you are going to have a piston in it that will boost the compession back up. you need to stay at to for N/A , only way to make the power on a unless you add a blower or nos.
    Another head you may look at is the AFR's or Air flow reaserch heads. They make a nice head as well and they flow great numbers. I guess what I should have said is you need heads that are flowed or flow very good. Thats were the power comes in. but you have to know what bottom end you are going to have so you can get the chamber volume right as well as the clearance you need for the valves depending on what lift cam you are going to be using.

    Put LT headers on it and call it day untill he can do it right. If it is high millage no sense. If low call Advanced induction or Lloyd Elliot, or buy an out of the box kit like the trickflow system, or air flow reasearch heads.

    How to Choose the Best LT1 Fuel Injectors?

    Engine performance highly depends on injection, concerning the fuel injector. And you have no way to compromise with certain aspects of quality.

    There are some key considerations to influence the frame towards a better outcome. Keeping the points in mind will get you the best fuel injectors for LT1.

    System Fitment

    The most obvious fact goes with the system specs, specifically the vehicle’s version. Not all designs can adopt the same gear. Therefore, you have to know your specs from the manual before purchase.

    Flow Rate vs. HP

    One peculiar consideration lies with the relation between flow rate & horsepower. For LT1 engines, the standard static flow rate should measure 42 lb-hr. And using mathematical formulas, you can count the horsepower.

    Frame Materials

    Almost all the top-quality injectors feature sturdy metal with composite plastic. You should look into the combo, especially the polymer portion. Metal quality with exterior surfacing also matters on longevity.

    Spray & Filter

    Intake filter media is one integral part of the system, letting you purify the flow. And the spray pattern should satisfy the OEM requirements. It implies a standard 15° spray pattern for any running engine.

    Internal Sealing

    Pre-installed gasket O-rings are essential to ensure a secure mechanical inside. You’re to check the whole platform closely, on its exterior side. It’s better to attend all the joints to understand any problems with the details.

    Extra Features

    Any individual injector comes with lots of mechanical specs. There are many involved features you should determine from the beginning. And you must ensure precise physical size to promote a direct replacement.

    Symptoms of Bad Fuel Injectors

    Defective or bad fuel injectors eventually cause severe engine damage. And certain symptoms are apparent upon the defect or failure. You better pay attention to the signs for prepping replacement.

    Rough Engine Idling Any vehicle’s Round Per Minute (RPM) depends on proper fuel injection. The defective injector fails to meet the engine’s demand. RPM gets decreased to cause rough idling, calling for restarts.

    Sputtering Vibrations Cylinders need a sufficient amount of fuel to fire themselves up. Reduced efficiency means fuel entrance in the cylinder system. And it causes noticeable vibration on every startup attempt.

    Frequent Misfiring Any malfunction in combustion assembly causes misfires. Other associated components may trigger the issue. But you have to check the entire system to determine the problems.

    Check Engine Light It’s another universal symptom of any defection action with the engine. Your ‘Check Engine Light on the dashboard will remain tuned on. Likewise, you’re to conduct a thorough search.

    Sudden Engine Surging Inconsistency in the spraying pattern will cause surging. Bad injectors will spray either a massive amount or a little amount. It deteriorates the combustion towards variable RPM with time.

    Fuel Puddling Leaks Failed O-ring opens the interior gasket. And the slight opening will keep getting larger with time. The spot will start spilling a fair amount of fuel on the underlying automotive parts.

    Startup Fuel Odor A heavy smell of fuel will hit your nose right after the startup attempt. It concerns an urgent engine repairment issue. No matter what happens, you should immediately consult a mechanic.

    Dropped Economy More fuel supply becomes evident with a failed injector. It directly means more refilling requirements from the station. Look at the system closely to determine the exact triggering cause.

    Failed Emission Test More leaks or more burns will contribute to the emission. Your system will keep emitting lots of burnt smoke. And you can leave the hope of passing the conducted emission test.

    Frequently Asked Questions (FAQs)

    Q: Are LS1 and LS6 injectors the same?

    Answer: The specs for LS1 & LS6 injectors appear the same from the outside. However, the recent versions of LS6 may differ from the originals.

    Q: How long does fuel injector cleaner take to work?

    Answer: There’s no defined timeframe to guarantee its outcome. But you should notice changes within 50 miles or two days.

    Q: How long should fuel injectors last?

    LT1 Fuel Injector Removal

    Step on in and see how to remove the Fuel Injectors on a Corvette LT1 engine. It takes very few tools and can be done in a matter of minutes.

    As with any automotive job, safety is a primary concern. Please use eye protection and keep any ignition sources away when working around gasoline.

    With that said, lets get started on a Corvette that is getting a set of LS1 injectors installed.

    The injectors are hidden underneath the covers on a Corvette.

    The passengers side cover just snaps off when pulled upward. In order to move the drivers side cover out of the way, the throttle cable needs to be removed from the bracket.

    Use a screwdriver to lift the plastic tab upwards to slide the cable out of the bracket.

    With the cable loose, the cover can be moved out of the way exposing the injectors.

    I used a fuel pressure gauge with a hose to bleed the fuel pressure down to zero before proceeding. The valve is located on the rear of the fuel rail.

    Now the injector connectors can be removed by pressing the wire clip and pulling upward. Do this for all 8 injectors.

    Remove the 4 bolts on top that secure the fuel rail with an 8mm socket. Also disconnect the hose that goes to the fuel pressure regulator.

    Lift the fuel rail upward, start with the rear then the front. The injectors come out with it.

    The fuel lines are still connected but swivel to allow you to set the rail upside down.

    Remove the retaining clips by sliding them away from the injector as shown.

    Carefully twist and pull the injector out of the fuel rail.

    That's all there is to it, and it only took a couple of tools.

    Simply reverse the procedure for the installation, making sure to put a little oil on the o-rings so they slide into the bores easily.

    Note: I will have to reprogram the engines PCM for the larger injectors.
