Glad you pointed out the pressure rating difference big point. I always wondered though about spray pattern. Back in the day when I made an m90 kit for my 4.0 mustang I used injectors off of a 03 Cobra Terminator which were rated at 39 lbs but they were meant for a four valve head two intake ports and my 4. slow was a two valve head one intake port. I didn't tune it I took it to someone so I don't know how the tuning worked out it still drove good even at idle but I always wondered if that spray pattern was getting more fuel hitting the walls and causing issues like that so there wasn't as good atomization and if that affects power and if so is it even big enough to matter and I know with like decapping I've heard that there are drivability issues where its idol is a little harder to get although it seems like that might be because of differing flow rates for injector rather than spray pattern I don't know maybe bothI just wondering if you ever tested this if you know
There's another guy that did that for most lS injectors I think it was like driveway something but he actually got the data from another guy who actually did the test but it's out there
Richard: There is no simple math to bench racing. Because when losing an argument to facts, someone always mentions ambient temp, ambient pressure, Bernoulli, hypereutectic drive manifolds, etc... Testing provides the facts. Checkbooks makes races, beer makes opinions.
Hi Richard great video! Looking at your matrix I want to check my math. I notice on the matrix for boosted (turbo) e85, your showing 95 lbs injectors supports up to 969 hp and a 80 lbs injectors supports up to 816 hp. The difference is 153 extra hp for the 95 lbs injectors. So for my 100 lbs injectors Im guessing they will support about 50 extra hp on top of that 969 hp on boosted e85. Basically I divide that 153 hp difference between the 95 lbs and 80 lbs injectors as shown. So 5lbs is about a third of that. Thus my exta 50 hp estimate for 100 lbs injectors on boosted e85 or about 969 + 50 is about 1019 hp for the 100 lbs injectors on turbo boosted e85. Also for fuel pressure your showing at 43 lbs for the 95 lbs injectors. I have twin good fuel pumps and a good high end boost referenced regulator that stays 58 to 60lbs on my 6.0 LS, older sloppy stage II cam, 799 heads, twin borg warner S366 T4 turbos. Should I estimate my injectors supporting a bit higher hp because of my higher fuel pressure at 58 to 60 lbs? Thanks for any advice or input here Richard!
Richard, love your videos. Spent many hours watching them, but I notice you don’t mention methanol very often. Is methanol a good fuel choice for a track car? I’m In the process of building a turbo 408. If you have any videos that might help let me know. I’ve looked through your 900+ videos but I might of over looked it. Thanks for all you do
We must have been taught by the same Mr miyagi because everything you say make sense and that's my beliefs especially how you explain a cam is a cam is a cam is a cam and you're not going to find a special cam for turbos nitrous blah blah blah blah blah blah LOL 100% true thanks and keep making these super dope videos when are you going to host engine Masters
VIDEO IDEA: Take a N/A Engine. Dyno it. Then strap a turbo onto it, but on the cold side, run the piping through some restrictions and then let it blow out to atmosphere. Point is, the turbo will have resistance *as if* it was pumping into an engine, but we can see the actual parasitic loss of from the back pressure from the turbo. It may be a little tricky to get the cold side just right, maybe you would need some type of Pressure Relief Valve to maintain a fixed but adjustable cold-side pressure? Feel free to DM me if you want any suggestions on this!
@@richardholdener1727 damn you're right., but at least we can correlate horsepower loss to back pressure. Regardless of how the 500hp of air is getting in there, it's getting in there. From there you just scale the horsepower based on boost. I'd imagine the pumping losses would be fairly linear, based on RPM and back pressure
But I think that's rated at 58 lb per hour on the fuel system you got to make sure you know what pressure the rating is from older cars with return fuel systems I think usually ran off 43 and a half so in that kind of a car it would be less like a 29 or something
Or perhaps a better question....does injector size make a difference to power ? Is oversizing as some do very bad ? Is there any difference in power between some cheap ass CNG 210's that they all use, vs something deemed good quality and designed for gasoline ? ( low end resolution is of course another matter )
Hi mate, I have a supercharged lsx 427. Just want to know what size fuel injectors I should run. It made 700hp at the wheels, runs on E85, fuel pressure is around 60 psi. Thanks. I have subscribed to your channel.
I’m looking for injectors now for my na 6.0 LS however I’ve narrowed it to snake eaters or deatschwerks on a Holley terminator x deatschwerks are available at like 44lbs snakes are larger at 60lbs what should I do?
@@richardholdener1727 Thanks 🙏 Rich .. I have one more for you if don't mind. Do I have to change anything like fuel lines and any hardware inside the tank needs to be replaced to support E85. The reason why I'm doing this Rich I live in California gas prices too high every morning passing this gas station seeing E85 for $2.89 a gallon
Hey Richard this is nothing to do with what you're talking about on your show right now I am dealing with an eaten blower problem I'd like to know if eaten blowers can 1 the eaten 90s in particular can 1 or be upside down or the 1 straight up I know they can go vertical and I only got 90 I just don't know 1 can go upside down from the other directly 180° of the other 1
Thanks Richard. I've been fighting a misfire around 2000 to 3500 rpm and was curious if my iniectors were too big. Sounds like it COULD be possible. I'm running 96lb NA around 500whp because i planned to run turbo but havent gotten that far. Seems to he fine putting around and at wot but cruise i can feel a p0300 and notice power kind of picking up and fading out. Wideband jumps lean for a fraction of a second. Ive checked about everything I possibly can. Could the 96lb on a 340lph pump be too much injector? It's on a vaccum regulator and i havent played with the pulse width any because I don't know enough to be messing with it. Im speed density tuned at the moment. Curious on your thoughts.
Richard what is you’re opinion of decapping stock injectors on a basic stock 5.3 turbo set up. I’m reading that most high output injectors are spraying streams vs a mist anyway so is there a real negative other than not knowing the exact flow rates? Thanks in advance
@@richardholdener1727 interesting. Looks like I better start saving my pennies!! I followed your lead and got a DNA Gt45 the other day. Doing my first turbo set up on my 5.3 can’t wait!!!
Would ford motor sport 80lb EV6 injectors be too much for a vortech 331? I want something with room to grow and E85 room. I estimate about 400-450whp in a SN95
I’ve been trying to figure out what injector I need. I have a brand new ls3 bored to 416 with aftermarket heads and cam. I plan on boosting it later down the road and running e85. I’m thinking I will be around 575hp na and want to make around 800 turboed later down the road. Trying to figure out an injector that will cover both ranges so I don’t have to purchase new injectors down the road. How big can you go and not have issues?
Ok so I’m a 5.3 ls with a single 88mm turbo . The motor is built and the turbo is rated to make 1,500hp what injectors size should I use ? Thanks in advance Richard.
Then tell me this.... My LS2 402 stroker NA was @ about 465 HP and in my '01 6 speed WS6 with stock LS1 injectors 28lb. Built exact same engine but bigger cam. Put it at 500 HP but went lean on the dyno @5500rpm. The cam's power range was to 7200rpm. We changed to 32lb injectors and added inline faster fuel pump. Ended up 540hp. But freeway fuel economy went from 29mpg to 26 mpg with stock pump and injectors where 29 was 345HP and 26 was 465HP. At 540HP non stock pump and injectors freeway mpg went to like 10mpg. Almost lost 70 percent of fuel economy for about 25 percent more HP and a noticeable speed increase that was not even worth that though. Was it just throwing gas out the exhaust unburned?
Ok so if an injector is rated at 143lbs @43 psi and you stick it in an ls wouldn’t the increase in pressure actually lower the lb of the injector if you run it @60. I know by seeing the test performed on fuel pumps some pumps actually put out the max pressure at the rated amount like a 535 walbro makes close to that @42-43lbs. I’m I on the right track or completely off lol
adding system pressure (which the pump works against) reduces pump flow. Adding system pressure to the injector (which works with the injector) increases injector flow. basically the pressure is in front of the pump and behind the injector.
@@richardholdener1727 ok what would be the ideal pressure to run that pump and injector on 93 or e85 being ls based in your opinion. Thank you for all you do miss the restaurant streams but hey in due time right
You say that an engine becomes less efficient at higher hp levels. More rich afr? Why does boost need a rich afr? If you are just adding more air, why do you need to run a rich afr?
You are increasing the cylinder pressure and heat. This gets the air/fuel mixture closer to its flashpoint which can cause preignition or detonation. That is what breaks pistons and bends rods. Run it richer to cool off the mixture. This is where the “lean is mean” saying comes into play. It’ll make more power, but you’re living on the edge.
GOD BLESS YOU! What on earth would we do without people that do nothing but pick apart everything they come across while contributing nothing themselves. WHAT A PRINCE among lowly men! Congratulations for being so special, ya miserable dipshit! 😘
I’m really confused about ev1/ev6 vs DENSO style injectors. They don’t even seem to use the same style seats? A company just told me they don’t sell ev6 anymore due to poor quality and they only run Bosch denso style high impedance injectors “and that’s what pretty much everyone else is running,” but unless I’m missing something it seems like a lot of people run ev1 low impedance and a lot are running ev6 and say it has better spray pattern. Does any of this even matter? Impedance does of course but not sure about style or spray pattern.
