What Fuel Injectors Are You Running?

[1995SHO9]

I am looking to get new fuel injectors and I was wondering what the other boosted guys are running. Particulary turbo'd SHO's, but I am interested in hearing about the S/C'd ones as well.

I heard that the Accel 48's are good. What is peoples experience with these, and is it a problem not running the stock SHO pintal cap?

Just curious why you're more interested in turbo SHO's injectors??? Turbo's are probably easier to size because they don't supply fuel to the extra power you never see spinning the blower.

I am running Accel disk-style 48lbs/hr injectors.

First off, thanks for that. Do you like them, do you have any problems since you arn't using the stock Pintal caps. I assume you bought these from SHO NUT, if so, are they a dirrect drop in?

And am more interested in injectors used in turbo applications because that is what I am using it for. But like I said, I still want to hear from either or, doesn't really matter. Thanks Jason

Boost is more or less... BOOST. Size them up for what you want and don't worry about how the boost is getting there.

No, I did not buy my injectors from Josh, however, I had Josh machine them to fit the stock injector to head O-rings. I bought mine from an inside-source at which I cannot say. No problems with the injectors at all.

even though people said they wouldnt work i used 39# cobra mustang injectors. i didnt have to mod the fuel rails or the caps on the injectors. all i had to do was change out the o-rings for different sized ones and they worked. also i had to change out the wiring harness plugs from ev1 to ev6. just thought id throw in my two cents since i got the "wrong" ones

 

[yamahaSHO]

Without changing out the connectors, it appears they could in fact be the wrong ones. However, you can make many things work for a car that weren't meant to

I started with 30 38 48 and 50 wich i use right know on the same turbocharger,wich bigger injectors throwing more fuel means more of a powerfull exhaust pulse and less turbo lag

 

[yamahaSHO]

Where'd you read that?

Unless that fuel is bypassing the cylinder or running through the cylinder during decel AND is being ignited in the exhaust prior to the turbo (anti-lag), then I fail to see your logic.

If you're looking for a more powerful exhaust pulse from the motor, you'll need to make a larger combution event in the chamber.

Really Big. 63 lbers with the fuel pressure raised to 48.5 psi, effectively 66.5 lbers ...

 

[yamahaSHO]

Ransom, are you using anything to drive those injectors? What boost are you hitting again?

I've been thinking of getting a smaller pulley...

 

[NCTaurusSHO]

did not read it anywhere. i have ben playing around with the same set up for 4 years know and every time I swap out the injectors to bigger size the turbo would act differntly hit harder and faster.

 

[yamahaSHO]

Placebo effect.... Or you have another issue that could use a look.

Injectors themselves aren't going to do that unless there was something else going on (not enough fuel in the first place/ or you had to change the tune/Apexi). Changing injectors to a larger size alone to get less lag is not happening. ****, fuel alone isnt' going to give you heat/flow.

 

[1993MTXSHO]

Dunno if you care about us little n/a guys, but I am running accel 36lb's that I got off josh to fit stock rails. I dropped them in and they seem to work just fine. I still need to get a good tune on my car though as it is pretty slow still, but I do not think it is fuel injector related as I had 3.2 injectors and had the same results. I might be at Brians Friday though, I hear you might be there Saturday so I might miss you, but if you're there Friday too for some reason, I'd be happy to let you know my setup and such

 

[NCTaurusSHO]

. We run a diesel shop here and truck drivers are crazy to wanting more boost and I have changed out many injectors to a bigger size in various applications for more boost and thats how its done. So I applied the same principal to my turbo and it worked. I did not have to change any tweece setings just the safc curve. Take the supercharger off your car and turbo it then you can see and feel the difference.

 

[yamahaSHO]

WTF are you trying to say?

Obviously bigger injectors are needed for MORE boost IF your current ones do not cut it, however, just adding more fuel on your setup isnt' going to net you a "powerfull exhaust pulse and less turbo lag" unless you're igniting it in the exhuast before the turbo OR clearly making more power.

I don't claim to know everything, however, this is quite obvious and what you're stating makes NO sense.

 

[NCTaurusSHO]

im so glad you are on the forum next question I need answerd I will ask you first.

 

[yamahaSHO]

You don't get it... 1995SHO9 is looking for some solid advice and you're not giving him anything to go by. Someone already blew his car up once , I don't think he wants it to happen again.

Seriously, grow up and search for some real answers instead of passing off BS.

I had nothing to do with the wrong injectors being put in the second time in his car they installesd the wrong injectors no pintel caps were used so the injector was not sealing in the head properly. The first injectors had a stumble only when you were off the throttle for a long period like one injector was not cutting off. . He came down we tuned the safc and it was smooth then on the way to maryland he was hot dogging with me and woop smoke broken and when I took it all apart that was when I found the messed up injector seals in the cylinder head this is on sunday repalced the messed up pistons so he could be at work on monday morning its not my fault It blew up no bodys fault its part of the performance life.

So when you raised the FP to 48.5, what did you need to change on the tune? I assume you would first have to up the Injector scalars for the same injectors. Upping the FP is in essence just increasing the injector flow.
Would that take care of it, or are there other things?

 

[yamahaSHO]

Hmm... I didn't blame you, but you sure are defensive.

I'm going to try an decipher this long run-on, of what looks to be a sentence(s)...

:braincramp:

FWIW, the injector doesn't "seal" on the pintle cap. The fuel pressure pushing the injector down seats the injectors on the rubber.

its not my fault It blew up no bodys fault its part of the performance life.

********. It's not "part of the performance life". That's part of the poor workmanship life.



Regardless, you haven't given a logical reason to how larger fuel injectors would reduce turbo lag.
