Yeah OP, you are also gonna need cat deletes or LTH, maybe some vibrant resonators 18 inch to weld on to your h pipe.

I want to keep my cats, I was hoping around the 750 rwhp mark they would be fine and survive. My cold starts are already too loud I live in a condo

mine were insane with the steeda x pipe after header install. I put the magniflow tru x on asap. Its perfect now and if you have active exhaust it works great still with the tru x

Stage 2 kit comes with DW400, 37lb injectors, denso spark plugs n all. Totally complete. Or atleast mine came with all that.
when did you take delivery of your kit? It has been evolving over time. I think the stage one kits come with 55lb injectors now from what i can see in the manual.

Does anyone know if running e85 is easier or harder on catalytic converters than 93?

It was 38lb injectors it came with. Late last summer. Lund told me not to pulley down below the 3.875 it came with until more fuel and with longtubes its like between 9-10lbs.

If you look at their website under the exclusive features if the kits it shows 55lb/hr for stage one and 72lb/hr for stage two and neither mentions anything about a pump nor is the pump in the most recent install instructions. They certainly have evolved the kits over time.

2018+ have different injector sizes and a DW400 pump.

Go ahead and put a fuel system on it. E85 is race gas compared to 93. These 12:1s will survive on 93 but IMO it’s just a matter of time before you find the right hot day, a second pull and break a ring land. Very muched needed in Florida. The ethanol cooling effect is also another big reason.

Superchargers in general are harder on cats but E burns cooler and overall will make them last as long or longer. Not going to be hurt though.

These trans will hold up reasonably well of you stay out of 7th. If you do long extended runs(another reason for E) over 700 and it will start slipping.

Pretty sure I will be going with a nice fore L2 staged system and running e85 most of the time currently. Ill run a tank of 93 once in a while to hopefully clean the system a bit. Also getting a 128mm filter with microglass filter since thats what ID recommends. Not 100% sure on the line type, im deciding between the PTFE steel braided and the FlexLP lines.

One thing I am slightly concerned about is heating up the fuel over time with a return style system which is why I am going staged and having the 2nd pump run only when needed. I would go brushless pumps to keep the heat down if they were an option, I'm still looking into that but I dont know if that is even an option. Hopefully road trips dont become an issue, I hear the fuel temps can get to 170 after 2 hours of driving because the fuel goes through the lines through the engine bay many times. I guess on e85 the gas mileage wont be good enough to drive more than around 2 hours straight anyway though without filling up. 2 hours at 80 mph is 160 miles, thats about a full tank of gas on e85 (maybe 2/3 of a tank). Ill keep it over 1/4 or 1/3 tank full though for safety and pump cooling.

Right now I am trying to decide on if I should do OPGs and also trying to decide what pulley to go with. Im thinking griptec 3.625 so it will be safe enough to run 93 occasionally. I wonder what power the car would make on e85 with a 3.625 pulley. Leaning away from doing OPG's and putting that money toward the fuel system but if the OPGs failed that would suck. I think its a low likelihood of OPG failure with an automatic car which will never hit the limiter in neutral like a stick car that missed a gear.


Also looking into fuel cooling radiator for the fuel to run through to stay cooler.

Also looking into holly hydramat so that without a fuel bucket in tank I wont have fueling issues when cornering

The heat mostly comes from the wattage of the motors. Size them for 850hp and you shouldn't have a problem running them all the time. If the second ever fails to kick on with a controller things could end badly. Big risk for a cheap part. E is much more tolerant of

If you installed the OPG yourself I think it’s worth it. Paying 1500 would rule it out. Haven’t seen to many 18+ break them with the new balancer.

3.625 should put you over 750.
