When did I say I'm the smartest man? I'm saying HP has nothing to do with an engine limit. It's not like if you hit 1400hp omg the engine is going to die. There's multiple factors included and saying boost doesn't affect the engine limit is plain wrong and dumb.

Now you and the other guy are going to tell me octane rating has nothing to do with an engine limit either... lol.

I can understand you don't like meth but it's not a "bad" system at all. People who say its bad either hear its bad or have gone on the cheap side. I can name you about 15 other cars in my area who have been running meth for 2+ years with no problem. Same pump and all.

Nitrous blows cars up does that mean its bad? It has components that can fail and cause catastrophic engine failure... Does that mean spray is bad?
I think meth is good. We put it back on out Grand National.

It works, no argument there.

Here's the issue:

When you are relying on meth for fuel, usually because the fuel system isn't adequate, you are walking a thin line. The slightest hiccup and you're done. Why gamble. Build the problem fuel system then add meth. That way if it fails you don't loose an engine. Just because it works in 100 cars doesn't mean it's fail proof. It fails all the time. Again, just bc you know a small percentage of people with it doesn't me it doesn't break.

The moral of the story is dont use meth as the fueling.

Who said anything about octane. Please stay on the topic. Who said boost doesn't affect the engine limit? Not me. If that was the care people would be making 20 psi all day long on a stock ls3. That's hardly the case.


One topic at a time. Right now it's methanol.

This whole discussion was about engine limits with the other genius kid who said boost doesn't affect engine limits.

Horsepower on a dyno doesn't mean jack, they are a tuning tool and nothing else. Track times are the only thing that matters. If you want to build a dyno queen go for it, meth works well for that, it's a cheap way to make more power.

This was my whole arguement in this thread, then you chimed this to my facepalm to 2ss4th...

I was never really arguing about meth... I just don't think it's "cheap" or used for "dyno queens..."

Hope that clears things up for you.

There's no magical boost number that will blow an engine, very few understand this, because very few of us build engines. Dynamic compression blows motors up, is boost part of that equation? Yes, but a small part of it. This is because a 14:1 CR motor running 5psi of boost is more likely to fail than a 9:1 CR motor running 5psi of boost. This is why boost by itself doesn't matter.

The other issue with trying to argue that boost is the way to measure failure rate is this, it measures restriction. So, a motor with ported heads, a ported manifold, larger primary headers, etc. will naturally result in lower boost levels, but will make more power. This is why I have to spin my blower faster to make the same amount of boost as Jamie, my motor's resistance to airflow is less. In the same way that Jamie and I have very different power bands and horsepower figures, but the same amount of boost.

Until you understand this, and I doubt you will, you shouldn't tell someone what is safe for a motor and what isn't.

OP ---

PERSONALLY .. Given adequate fuel, I don't like to boost NA stock motors higher than 10#'s ...

Depending on your end game, and purpose with the car, bolt ons + cam and 10#s makes for a very fun car.
