I'm not against injector upgrades either. It's just that I've been well acclimated to the real world findings of fuel system limits as compared to the theorized limits found from calculations.

People calculate all the time what these fuel systems should be able to do, but in the real world, they handle a minimum of 475 RWHP and in some cases as much as 530 RWHP. How far past the theorized maximum limit of 100% duty cycle does that put us?

Well my Fuel Pressure hits 58-59 psi at WOT and sits at 62-63psi at Idle. -- However someone told me that just because the pressure is there doesn't mean the flow is there. I've been talking around and to friends and a well known engine builder told me that he runs stock 28lb injectors up to 600hp and then upgrades, he just puts a bigger fuel pump in.

I think I'm just gonna upgrade now and be prepared for later, with a LSX intake and AFR heads in the future + a blower I know I'm gonna need it at some point.

"However someone told me that just because the pressure is there doesn't mean the flow is there."

Why? The only reason I can see the flow wouldn't be there if the fuel pressure made it to the injector would be if the injector were faulty, locking up, or clogged.

Well tonight I should have some results approx 7:00 est. Colonel were there any issues with the SLP underdrive pulleys causing a false knock?

Colonel

There were serious issues with the Whisper UD pulleys. I know, I was unfortunate enough to have one of the POSs. It caused all kinds of false KR.

I haven't really heard any negatives about the SLPs. I know the ASPs are great (what I run) but I don't know if that's where SLP gets theirs. I certainly wouldn't rule out that possiblity.

Here is the new file. From the looks of it, it seems to be a real spark knock. With 93 I was getting around 4* of KR with 107 I think I got a max of 1.5*

Here are the logs


How should I approach this using Edit shou I go a little fatter on in the IFR table or should I back off the timming in the High Octane tables

I have seen mustangs at much lower fuel pressure make 300rwhp on their stock injectors.. Which are 19#ers. I have seen many go to 450rwhp with al years of our cars on stock injectors and pumps. Now I feel anything over that you have some money in it anyways just put some SVO 30#ers in and a walbro intank.

I am putting 30#ers in mine now only because I have a hung injector and have a new motor in the works.

440rwhp and I still have plenty of fuel left with my setup.
