The safety E85 gives for the engine is the best money spent with boost and 12:1 compression.

Its an incredible time to be live and into these cars with E85 stations almost everywhere.

So long as you don't live in AZ :) E85 is at 4 stations and they have been plagued by reports of water in the tanks.

Other places advertise it but most of the time it's E54. I would love to upgrade and there is a station right down the street from me but it's too sketchy for me to pull the plug.

E54 is still better then pump gas

Water in fuel is not good :(

I would go the E54 route but not too many people will/have tuned for it with the Roush kit. I would have to have someone local do it and would prefer to have PBD do it. Guess I need to look and see if they will do a Flex tune.

I know a guy that could handle e54

(but you can’t go wrong with pbd if that’s your preference )

So.. Would your recommendation be the same? BAP, Injectors, etc.?

Car only has 2k miles on it so I'm hesitant to spend a bunch of money on a fuel system but it may be coming sooner rather than later since I hardly ever drive it :)

I have access to a dyno that allows remote tuning as well.

dw400 and bap for sure, you might be able to get away with your 47lb port side but you won’t have the safety factor the larger Port injectors give you if you run into trouble on the low side

An example would be your fuel pump starts to fail and low side pressure drops. With low side pressure down the hpfp can’t deliver the same volume to the DI injectors as it could with low side at 65psi , id1050 and really dump some fuel even at lower pressure to make up the difference and potentially save your engine

this is why it’s common to recommend much larger then the customers need.

Also you could always run canned race E85 and have better resale of your used part in the future

Do it the right way and spend the money. 1500$ fuel system vs a 5k engine

My goal was for the car to still drive stock, not have loud aftermarket pumps, and keep close to stock to retain reliability.
Ive built so many cars and Its easy for me to get carried away and make the car not reliable enough to enjoy. I dont plan on dropping the pulley so I should be safe and it sure is fast. It doesnt feel like the same car.
Also, if (when) I decide to sell the car, I can put everything back in it in a couple of hours, sell the barely used parts and go on my way.
Full mod list;
MAK cat less down pipes
Magnaflow resonator
DW400
BAP
IDI1050 injectors.
I am on E85 and tuned.
Before I switched to E85, I was running near max timing for a blower car easily on 93 octane + boostane (100 octane mix).
Upgrading the fuel system and switching to E85 provides an extra layer of safety as well as definitely more power.
In relatively the same DA, My car went from 6.8 to 6.3 using draggy 60-130

Good parts list, Im going Fore dual system and i have longtubes catless, 3'' collector back. How does she run? Dyno? 6.3 is moving pretty well for being on the stock pulley essentially.

Just cause we all love OPG talk, anyone make the change to billet OPG and CS in hopes of avoiding damage from the crank strain from the blower?

In my opinion if you’re capable of doing them your self or are made out of money they’re pretty inexpensive.

I did not do them at first when I installed my Whipple but with Covid I got a couple months off and had extra money so I figured why not

I'm looking at a hellion top mount kit, I'm worried pushing that 900whp area with stock OPG and CS would be a dumb idea. Just the idea of paying 25% of a built shortblock to have them installed seems off putting
