What type of peak performance number are achievable running this system with forged internals on 93 octane?

Is there anyone using this kit primarily running on pump gas that also has a secondary map for e85 that they run for track or other occasions? I would imagine this would be no different than a fail safe map and perhaps swapping a pulley.

Too many variables to even guess.

Flex fuel would do everything you want with one map. Mix and match e85 and gasoline, and the flex fuel tune adjusts on the fly.

I had that occur one time. Change the tensioner. After I did that it never happened again.

My goal ultimately would be to make 400-450whp at a minimum on e85 but if achievable on pump gas would be even better clearly. But high 300s on pump gas with the upward mobility of 400-450 on e85 would be a requirement for me to go ahead with forging internals and sticking with the FA20 instead of going LS3.

I'm just doing a bit of forward thinking. I plan on moving forward with the eforce on the stock block but with a plan in mind of putting together the next step of either a built block or a LS3.

When are you installing the kit? I’m curious what your initial thoughts are.

Possible with a built engine? Yes.

I'm doing everything myself and I work about 70 plus hours a week so it's a little slow going right now but I currently have the kit ready to install as soon as I finish putting in a new clutch, water pump, and idler pulley.

Outside of the drive to pick up the vehicle from where I bought it I've put less than 10 miles on it before I had it on jack stands and the interior pulled out. I'm just doing most everything all at once.

On 93oct?

What type of reliability would you say comes with that sort of output? Let's say you have good coolant/oil temps, good tune, on a scale from 1 to 10 with 1 being completely stock reliability and 10 being reliability of a top fuel car.

Depends entirely on the quality of your build, your maintenance and driving habits, as well as use case.

You're well beyond the hp/liter any auto maker in the world would ever put a warranty on. Even Koenigsegg money doesn't get you the hp/liter you're looking for.

Well said. Leave it to a tuner to feed you spool full of reality.

Currently I'd be content with a reliable-ish 280whp to track over the summer. I guess for my goals it is fighting an up hill battle to do anything other than a swap if I want a higher degree of reliability.

280whp is well into proven territory. 350whp is also considered reliable at this point, given proper supporting mods.

Yes, these numbers for track use, which typically requires much more than a "once in a while highway onramp" street car.

This year will be my first time tracking a car non-drag and I'm sure I'll be hooked. So reliability to stay racing and less time replacing and repairing is a big focus especially considering my limited time away from work. Although, depending on how the car feels in this aspect I may be content for quite some time.

It just seems like the point of diminishing returns on the FA20 is right where I want the car to be at +400 and to even get there from where I'm at I estimate a built shorty, fuel supply, tune, to be an additional $4k.
Which at that point the initial SC build investment is only $4k away from a Sikky/GM Crate LS3 build. Hard to justify an unstable 400ish hp over spending $4k more on a rock solid 500ish hp.

I would think the driving characteristics of the car would change a lot when swaping an LS3 in place of the FA20 regarding weight distribution and center of gravity. If just for drag I could see it, but for track I would be hesitant.

This was my original hesitation. Weight wise it's only a +20-lb difference. As distribution goes, with the Sikky kit It's almost exactly a 50/50 split with how far back the engine can be mounted.

Just based on sheer weight numbers distribution the e-force is actually adding more weight and with all that mass being top heavy and as far forward as possible with the addition of the cooler and all of its fluid this would seem to me to have a greater effect on that distribution than the LS3 *shrug*. If nothing else I would say it's similar.
