thats the ones I use.....

The only problem is finding a way to mount it. I had to made a sleeve and thread it on both end and put a 90 elbow on the opposite side....you could buy a brass female to female tho. Then i put a washer under the nozzle head and on the outside of the silicone boot its in so the fittings wouldnt pull through the boot.

Nice. If only I could find free shipping. It's as much as the nozzle lol.

mcmaster used to charge outrageous shipping but last few times it was really cheap.

It was like $8 for a nozzle and $10 for shipping

Its a shame they aren't easier to install (or cheaper), but fuel injectors make amazing nozzles for a ton of reasons.

Seems to be a trend in methanol cars, adding 1-3 injectors in the charge pipe even on 16 injector combos.

Well I’m at a stopping point. But honestly, I don’t think I want to push things any further. The thing runs like a mf’er now. On 18psi it’s much stronger that it ever has been. I added a little timing back. Put a 10gph nozzle in and added another bottle of heet to my washer tank. My afr is 11.0 at 265pka with a 95% duty cycle. So I’m out of injector. Yea I was getting 22-23psi (turned up to the highest setting which was only at 75% duty cycle on the solenoid) in second gear and yea. It pulls hard asf. I took .5% out the duty cycle to try and lower it a little because that was with the cutout closed! It would probably be 26 if I had opened it. But I was hitting the 24psi boost cut in second anyways. Well. I couldn’t do e85 at this point if I wanted to. I think I’m gonna add a little more fuel pressure to it as a safety. I’d rather the afr be 10.8-10.9 anyways.

what do you have for fuel system? Supply/return lines, fuel pump, injectors?

Created my own return using the Fbody factory T that is sort of a dummy return, removed the intake regulator and put a boost referenced FPR where that T fitting was. Walbro 450 with a hot wire kit. 60lbers.

and you say you are north of 700whp? I mush be making way more than I thinking I am. I have a return system with an aeromotive regulator, two aeromotive 340’s, 60psi base fuel pressure with 1:1 rise on regulator, 80lb dekas and at 22-23psi I’m at 95% duty cycle. That’s including a 10gph nozzle being sprayed.

I'm running the same base pressure (obviously at vacuum when idling its less than this). Have you measured/calculated your airflow? Have you logged fuel pressure in boost? You should see 60+22=82 psi of fuel pressure at max boost, if not then your duty cycle isn't accurate. Do you have a hot wire kit and verified voltage at the pumps? All that stuff can mess with your DC falsely.

Based on my logged airflow its pretty easy to figure out a ballpark power. I've seen 44lb/min of airflow with a 50% scaled tune=88lb min of real measured airflow-any BEN error (1.5% rich when I checked a log)=~86.5lb/min x.85=~740whp at ~16 psi.

i don’t have a fuel pressure sensor. Only way I can do that is a manual gauge. I haven’t done that lately. I have 10 gauge high strand silicon jacket wiring going to my pumps. I have upgraded wiring in the car, added additional grounds and 4 gauge going to the alternator. I used to do 12v wiring for a living so my crimps are on point and I solder where I can. I don’t use butt connectors.
I’m not using a maf so I’m not sure if I can measure airflow.

you sure you aren’t calculating for fwhp and not wheel hp?

lb/min of airflow is FWHP, thats why I multiply by .85 to get RWHP. I would get a fuel pressure transducer on your car. They're all of $10 and can wire into the EGR pintle position so you can log it with EFI Live or HPT. You can calculate your airflow from this just make sure you account for your BEN error:

@Kfxguy thought you would like this:

Plug in your info and see what it spits out. This is why I think your IDC is off. Don't forget your 80lbers are rated at 3 bar typically and you're running 4 bar of base fuel pressure so they're more like 108lb/hr.

it says 963 at the tire. Which I know it isn’t that high. The turbo isn’t capable of that. I’m on pump gas and I know it has an option for that but I just don’t think pump gas would (easily) carry it that far. My fuel line is likely undersized at 3/8” and I’m using stock rails with a 5/16 return. My guess is probably 750+. I wanna say around 800 but that’s a lofty estimate. But it does pull hard asf. So hard it makes me nervous that I’m going to explode something. I don’t understand how this 60e is holding it for the amount of time it has.

ddnspider

iTrader: (26)

That's why I think you IDC isn't accurate. Obviously the log says that, but it's likely that heigh because you're either dropping voltage at the pump at high rpm or dropping fuel pressure. Same result either way if you tune to the drop.

Those the nozzles devils own use to sell. The ones I ran in my 3.8 turbo buick. They came with a rubber/steal washer so they would seat and seal on piping. MCmaster has a warehouse down the street from me. Its nice to order things and get them the same day. though the ******* won't let me pick it up and save the shipping cost.

ddnspider

That's super nice having them local. I'd be bitter too if I couldn't pickup if they were local. Good to know that they're a solid nozzle. Planning to build myself another kit for the DD now that I've messed with WMI enough. Works so well for the cost/effort.

As 93 prices escalate, $2 a gallon fuel works even better in the cost/effort calculation. Seems every new gas station has been outfitted with E85 around here, always run into car guys at the pump as well.

Still bitter about not having E85 local to me either. The closest 1 is probably 45 min otherwise the next location is over an hour away.
