Looking at ESS, recommendations for supporting mods

[mlj32]

I was recently in an accident in my mustang and as a treat I’m looking to get an ESS kit once the car is back. I’m targeting 750-800whp on e85. What supporting mods would be recommended for this type of set up.

Currently only mods are coilovers and kooks catless headers.

Gt350 axle, driver side.

If you're going for 800 rwhp on e85 you'll want some sort of fuel system.

I would do the billet oil pump gear and sprocket. You already done the headers. Might as well add that extra safety net.

Thats crazy, I didn’t realize they did that on a sealed motor I would’ve figured at least oil pump gears. Maybe the gen4 isnt quite as weak

There have been many opinions on this; it has been said that if it is an automatic vehicle, you can get away with the stock oil pump gears. If manual, then get the gears.

I have a manual, so that is why I did the gears.

This. The working theory is that manual guys miss shifts and hit hard limiters or do the old 1-2-1 thing and no hard limiter is going to stop you from hitting the physical limit of the internals. And that brittle oil pump gear getting rattled that hard back and forth against the limiter is when the damage happens.

The auto cars hit soft limits and trans limits well before any hard limiter and there's really no missing a gear to that degree without multiple limiters catching it.

I dont know of an auto car that broke them that wasnt making 1000+ Hp and pushing RPMs way over 8k. THere's been auto F150s and other mustangs that have, but nothing for what most of us will do.

So thats the theory. And it for sure has merit. Manual cars are simply harder on the hardware especially when clutch protection is disabled along with raised limits and removed tq management. I warn my manual guys about missing shifts when they want to be able to bang gears at 7800+. BE CAREFUL. Even NA cars at that point.
