380whp is what is "considered" max safe on 93. Some tuners want to stop between 350-360whp on 93. You "can" get 380-400whp with a drop in turbo and 93 but one bad tank of 93 could do you in if not careful.

With e30 380-400whp effectively safely with e85 can squeeze more.

 

I'm not an expert for sure, but I would go a step further in caution and say that 350 whp is the upper limit of safe. I base this from what I learned from the tuner I hired. He put on an intercooler, charge pipes, catch can, bov, waste gate and custom 93 tune with the goal of meeting my request to balance safety and longevity of the engine with the max power. I now have 334 whp and 415 torque to the wheels. He stated - "There's a lot more power in there, but not if safety is your main goal".

Honestly, to me it now has a huge increase in power on tap that no longer falls flat but just keeps pulling, to the point that I really don't think it needs more or feels like more would be safe. Again, this is just my opinion, but if I want more power then I think a GT would be the way to go because to me at the power levels I'm at now, feels like the engine is getting pushed hard enough. I've driven it hard to very hard with no issues, street and highway, no track, but multiple hard pulls in a row, 3 to 6 1/4 mile and 0 to 60 runs mixed together, and have been out on many occasions with 20 to 30 minutes of running it up and down through the gears at WOT much of the time, with no issues. Again, this is just opinion based upon feelings, lol, and I hate that feelings crap, but in this case I'm going with it. The seat of the pants feel that I get says that it's putting out all the power it can and more would be asking for trouble. Now, on a 50 mph roll when I go WOT I'm passing 110 where before I would be passing 80, and I know it still is pulling hard at 145 so I really don't need any more power. Would a GT pull harder and accelerate faster? I'm sure it would but I don't think it would make any sense in trying to turn my ecoboost into a GT.

Good luck and have fun!

 

Okay so should I put in my nx2 turbo into the car and possibly push 380-400 hp since that’s the max on pumped gas? But what’s do you mean one bad tank of 93? Also I understand 350 might be the safety limit because of your tuner but since I bought the nx2 I was just expecting more power but of course not trying to blow up my engine and be safe. I guess what I’m trying to say is I’m trying to push it to the max safety limit with the car still being safe and that’s what I’m trying to figure out if that’s 350whp,380 or maybe 400 but at the end of the day I’m probably keeping the car for another one- two years max and selling it

 

Not all "93" is actually "93" sometimes the quality is bad. Also certain stations just seem to always have good quality. Some less. A bad tank can cause predetonation when pushing power to the limits. Always good to give yourself some head room. You will definitely need to monitor your OAR. Personally i wouldn't push pass 360 on stock with 93. But e30 i would push to near 400.

Walmart locally always has good quality 93. My OAR maintains a -1.

BP stations nearby drop me to -.94

 

Hello I have a 2018 10 speed automatic ecoboost mustang and currently I have a Cobb tune (93 octane) with a mishimoto Intercooler and charge pipes,down pipe, Ford performance/ borla cat back exhaust, a steeda throttle body spacer, ngk spark plugs,roush intake,shortie bov from turbo smart, a upr dual valve catch can.
Currently I’m pushing all of these together and will get a pd tune very soon and also bought a nx2 turbo with an upgrade waste gate
My question is I currently have a stock block and don’t see myself upgrading it but I do know the safety limit on these is around 420ish whp and I’m only trying to make around 400 whp since I’m only going to run 93 and on rare occasions e85 but really only 93. I’m just trying to see if this is safe or if I should even install the nx2 because I don’t want the nx2 to be “to much for the car”. it’s a daily for my wife for now until I get another car for her but regardless she drives like a grandma so it won’t be pushed at all only when I would drive it on the weekends but even then I wouldn’t push it to much.
my only concern is if this is safe because I don’t want to go “eco boom” and blow up my engine.

thank you for reading all of this lol and helping me understand and reach my goal!!!

I would talk to Ryan from PD. I would be surprised if he said that you were running within safe limits right now. Did you have your car dyno'd for the numbers you are getting?

 

i think you read wrong? I’m trying to reach that right now I don’t know what I’m pushing but next week I’m purchasing a pd tune from Ryan and have yet to install the nx2 since I’m not sure if it’s safe too or if it will push my engine too much if so I’d rather not put it in and sell it

 

I'm not as concerned about horse power as I am about high heat. Heat, both internal and external, can do a lot of damage to an engine.
Adding a performance intercooler and motor oil cooler can help reduce the internal engine temperatures.
As opening up your hood vents and insulating your turbocharger can reduce the external temperatures of your engine.

 

...I do know the safety limit on these is around 420ish whp and I’m only trying to make around 400 whp...

What is this claim based on? There is only a single auto manufacturer worldwide selling a production car with a 400 hp 4cyl--this engineering feat is not easy or inexpensive. How do you define "safety limit" and how do you know it's 420 whp for the 2.3L EcoBoost? Do you have engineering data on this, or is it based on marketing materials from people selling power upgrades?

Doubtful.

 

Instead of insinuating I'm a liar why not go get the data yourself and prove me one?

 

This had been a truly enlightening discussion. I hope you all have an enjoyable day. Peace.

 

This convo went south fast LMAO

 

Yeah, somebody got their passive aggressive panties in a bunch.
