just wondering how far dual 465’s have taken you and will take you on E85. I’ll be 4.6 with 11.1:1 with twin turbos.

I second that thought- I don't think a 1300 injector will cut it either probably need 1700's . or dam close - I assume the 1100+ is rwhp.

Yea 1,100 rear. I’ll be doing the Holley 160’s with the dominator ecu
If 1100 through an auto, you will be maxed out at that power level on twin 465 pumps. Will definitely need 3 pumps. Fore is nice, but also consider the CPe triple pump hat. It's a very high quality piece.

I would do the Bosch 210's over the Holley 160's also. They give you room to grow and are a better injector. https://www.ebay.com/itm/BOSCH-Gas-...e=STRK:MEBIDX:IT&_trksid=p2060353.m1438.l2649

I have seen 1000 RWHP out of a few Turbo Coyote's, but that seems to be it. If shooting for more, then get the triple pump for sure.

I would also look into a external pump. Weldon 2035a. Badass pump with amazing customer service

Also fwiw I’m at 860rwhp with a JT trim 10:1 engine. I maxed out id1300s already. I just stepped up to 1700s. You might be ok with the 160s. But better safe than sorry. Good choice on the dominator ecu. I love mine

^^ how did you max out id1300's on 860 rwhp - Seems odd usually id1000's will support 850 rwhp on e85 with twin 465's.

Maxing injectors has a lot more factors than you would think ( type of power adder/bsfc, rpm range, fuel temperature, displacement, compression, ethanol percentage etc). One of the bigger factors often overlooked is boost level. If you running 20psi of boost to get 850rwhp you will have a lower duty cycle than if you have to run 30psi of boost to get the same 850rwhp as the injector has to work harder to deliver the right amount of fuel and over come boost in the manifold.

When picking out injectors, guys don't often account for going static or the fact that you can never really effectively operate the injector at max advertised flow. Most go static in the 91-93% duty cycle range. So for safety, its a good practice to shoot for 80% duty cycle range max when using a calculator to give you 10% overhead. So basicly you should calculate no more than 80-90% of the advertised flow rate tops right off the bat.

To add more data to the thread, I maxed 1000cc's on e85 at 800rwhp with a 3 bar base pressure (43psi) at 18lbs of boost on my personal car. Also seen 1300's max at 930rwhp on one setup, they were sold to upgrade and then made 1050rwhp on the next car at the same base pressure. In other words results vary, sometimes wildly.

Also something to keep in mind, the original 1300's actually actual flowed in the mid 1200cc range, where as the newer ones now called 1300X's flow in the mid to low 1300cc range.

Yep. My engine is 10:1, stg3 heads, custom cams, JT-trim vortech at 16.4psi@6400 rpm but the car would spin 8-8400rpm.. I've seen them make more power on other combo's.. But on mine they are maxed out. Or what we feel safe with.. This was base pressure set at 50psi as well, and a big external weldon fuel pump
