Stock 1.6......How much boost?
How much boost can a stock 1.6 engine handle without having to do any major engine work?
|
17.3psi for 17 minutes, then it goes boom.
|
Bond, you're an idiot, everyone knows it's 17.2 and if you go 1/10th of a pound over that it detonates. :jerkit:
|
It may detonate, but it will last for 17 minutes :noob:
|
Basically they're Saying it all varies between motors, and how good your tune is. And you'll figure out how much boost is too much if you read about half of the threads here.

why cant anyone ever answer questions honestly? Do you think that answer of yours did anything for me other than piss me off? People like you are why I hate forums! I am only here for the select few that can actually pass on some useful info. Please be serious!

SO PLEASE STOP ASKING QUESTIONS THAT CAN'T BE ANSWERED AND NOT EXPECT TO TAKE IT UP THE ASS. moooooooaaaaaaaaaaaaaaaaaaaaaar booost! |
First boost is a relative term. 10 psi on a GT 2560 does not = 10 psi GT30R. Its better to think of WHP which our blocks tend to start bending rods around 240-250 whp. So safely i would expect 220 whp (although we have had failures this low).

Ok, allow me to answer your question honestly and directly: There is no single, straightforward, direct answer. (That was the answer.) Too many variables affect the performance of the turbo system, the engine's ability to turn air into power, the engine's ability not to destroy itself, etc. One of the most important things you need to realize is that there is simply not a fixed relationship between PSI and power, even assuming the engine itself to be a constant. I could run 50 PSI reliably on a stock bottom end if I simply installed cams with 0.1" lift. I'd probably make about 40 HP. Conversely, I could break all four pistons in half with only 10 PSI if I tried hard enough. Even if fuel and ignition timing are absolutely optimal, the exhaust is wide open, etc., you'll still get more power using, say, a GT2860 turbo at 10 PSI than you will out of a GT2554 at 13 PSI. Until you understand why this is, I'd suggest not experimenting to see how much boost your engine will take. I cannot strongly enough suggest that you obtain this book and read it: Amazon.com: Maximum Boost: Designing, Testing, and Installing Turbocharger Systems (Engineering and Performance) (9780837601601): Corky Bell: Books |

given your knowledge of boost i predict any positive manifold pressure would thrash even a factory boosted motor so plz, either read and learn for yourself or /end yourself and go drive a kia.

depends on turbo size, two turbos can flow 10psi but each one has a different flow rate, how much air is being pushed in at that psi which raises cylinder pressure = boom. a friend of mine that is on this forum is pushing 16psi with water/meth injection and his shit is running hard. stock 1.6l in a 90'

It is also said, anything above 12psi regardless of the mass airflow behind it and the rings will fail, however, I have seen no real evidence of this, it's the rule of thumb that FM and BEGi adhere to. |
Right then, on to more pressing matters gentlemen. I have been wondering for some time, How much do heavy things weigh?
|
Im an idiot but I have to "get more better knowledge" Learn how to speak before you talk shit!
Thank you Braineack! You seem to be the only person in this forum that answers anything seriously. What people dont realize is that they were once new to this as well, so how am I supposed to learn when you guys just give me smart ass answers and mock me? |
I've been here two years, lurk everyday and still learning. See my post count? Use the search function :/.
