Built lme/ysi LT1 fuel system??
I am about to get my built motor from lme and was wondering if I can get away with dual nozzles meth and lt4 hpfp to achieve 900 to 950whp on 93/meth. Stock lt1 injectors and low side.
My setup is built lme short block with ysi blower. Going to be running 8.25 percent lower and 3.00 inch upper with 8 rib. I know the belt slip issue which is why I am staying with 3 inch blower pulley. Any suggestion would be appreciated. I have heard lt1 injectors will do just about ok. Reason I dont want to spend money on injectors is because I will be doing direct port injection later on.

In my opinion, not only will you need the LT4 injectors, but you will need to be spraying a metric butt ton of meth. As in probably triple nozzle. I had mine setup with LT4 HPFP, LT4 injectors and rails, and twin M15 nozzles for 30 GPH an hour and I was up to 850rwhp. I added E85 but could only run about 40% before running out of fuel volume. So, that would get you up to about 900 wheel or so..

once you have a flex fuel sensor installed and the E85 bits and pieces are added to the tune file for it then it will adjust based on what mix you have in there. Simply put, don't try to run more than half...

You will be spraying a **** ton of meth to achieve that kind of power. Save the cash you spent on the short block and keep the meth reasonable till you get the port injection on it. Not a fan of meth for fuel....

Well I can confirm I had the setup the OP is asking if possible.
I ran the novi1500 at 16psi with built short block from LME & dual nozzle 15s. I had lt4 pump and injectors and cam 32% lobe. Also ran flex fuel at about e50. Car made 900-930 wheel depending on the day.
3 inch pulley on a ysi will be about 16 psi maybe a tad more. I’d run the 3.3 and keep boost reasonable and you will for sure need LT4 pump and injectors.
Maybe go ahead and do the low side system and let it eat.
