Put 87 in it and see if it makes the same power.

Oh definitely. Thanks.

Why can’t you just answer the question man. Trolling because you think I’m trolling is next level.

e50 is as far as you will need or want to push the stock turbo. Nobody is running port injection on a stock turbo b58. Nobody.

Thank you, I appreciate the directness.

It just makes more difficult to do when someone says the opposing thing, that my thoughts are true too. This is why I am asking. Definitely doesn’t seem like it’s the only answer.

This is why it's important to answer questions like, what are your goals for the car? I see you have other threads talking about putting a pure 800 and so forth.

I get it can be a confusing space at first but you if you have a goal in mind, You will surely find answers here.

The hp isn’t important to me. I am at 480/570 on e50 with bolt ons.

My goal is to not have to mix (run full e85) which is why I am adding PI, upgrading fuel system.

I know it’s suggested to run a bigger turbo to give me extra headroom as pushing 500hp on stock turbo is riskier. But I’m just trying to verify if that really is the way to go. Even now at 480hp, theoretically I should upgrade my turbo because it’s pushing to the max already.

My thinking is if I’m at 480hp, if I just keep the tune at 480hp, I should be okay as that’s where I’m at now?

So let me get this straight... You want to get a fuel pump and port injection/intake manifold to run e85. You are going to need a flex fuel kit because E content will fluctuate. You will also need a new flex tune. The gains you see on the stock turbo will be VERY minimal for the amount you spend. Likely $3k+

Not to mention at such high E levels, you may run lean and blow your shit up. Are you being serious?

Yes. I’m being serious. Again, not trolling. I am legit just looking for direct answers to see what I want to do is indeed possible.

Whether it’s worth it or not, that’s not what I am asking about. Worth varies per person. For example, people add carbon fiber to their car or pay over msrp.

It wouldn’t run lean if it’s on a flex tune though?

You are gonna make less power on full E85. You will run the risk of your pump failing, going lean and blowing up the car. Are you hearing me?! Even with a flex tune, YOU MIGHT BLOW UP YOUR CAR.

Sure you can "tune" for it but many people FAR smarter than you and I have tested and have found the sweet spot for the hpfp seems to be e50. Why try to re-invent the wheel?

How is the pump going to fail if I am going to do the upgrade for that? How is it going to run lean with all the proper supporting mods?

People are far smarter for sure, which is who I’m looking for on this forum. I’m not trying to reinvent the wheel. I’m just trying to understand.

yes
I am currently making 480 whp on e50. By going e85, will I be technically making more power, less power, or the same?

I don’t want to upgrade the turbo because I don’t think I’ll ever need or want that much power because I’ll have to upgrade the trans. But I will get a bigger turbo to run e85 more efficiently, if needed.
you're ridiculously contradicting. going from a proper E50 tune to E85 tune w/ supporting fuel mods, you'll see a major gain in torque

at E50 power levels you're already risking transmission. going to E85 will put further at risk. upgrading turbo will put further at risk.

solution: fuel mods, E85, ask to remain at same power levels... spending all that money just to stand in one gas pump. that's it. that's the thread. don't question me. done.
