Ok i'm assuming he meant just pump gas lol..

I'm running...well WAS running 12 psi on my setup on pump gas....After my new kit i'd like to run to 14 on pump but not sure if that's wise...

 

why not? our internals are forged, as long as there is no detonation or anything, then i think it will last

and if it only lasts 5 years instead of 10 years, then another engine is only $1500

 

you want to run 15+psi on stock headgasket, you will surely be running race gas...

That's why people buy thicker headgaskets, to be able to run 15+psi without race gas

 

Depends on your manifold and turbo that you go with . Stock gasket pump gas is good for 500whp past 500 you will need race gas. Like a tubular with a 6262 won't take u 15 psi to get to over 500 whp so it's dependent on your setup

 

The guy who said that to you shouldnt be tuning period.
if you dont understand engine dynamics, then stay away from tuning.
Dynamic compression is the key your guy doesnt understand here.
Stock s2k engines have now proven to be capable over well over 700 HP.
A thicker headgasket is NOT the way to go, and never will be. Increasing deck is bad no matter how you look at it. The compression has to match the cam profile or the entire setup is out of balance. Will it work, make HP and drive...sure. But the tuner now has even more driveability work to do in the tune, and 95% of tuners dont do any driveability tuning anyways. Let alone knowing more is needed with a stupid spongecake for a head gasket.
Read a bit, you can come to your own conclusion.

 

hence why its better to say you can't go over, say, 15psi then saying you can't go over 500hp because hp depends on your setup where pressure doesn't. Independent variable vs dependent variable...

 

lol @ spongecake

 

I think the "setup" comment was pretty dead on. For example. My old godspeed kit... as well as it was, i wouldnt wanna run to high of boost on it because it's just not that efficient compared to the tubular mani kits ect.

having a log, with a smaller turbo, and not enough flowing air really contributes to heat and detonation a lot quicker than lets say, a kit with equal length many, a nice bigger turbo, efficient way to expell the gas, i.e. big enough exhaust or what have you.

It would be a lot safer and make more power at 15psi on a maze kit, vs my godspeed kit because my turbo will just be blowing alot of hot air on this motor and setup..

take the 50 trim and put it on a DSM or evo that's pretty much made for it, is a different story though.

 

So ive read all of this and with a 3" exhaust no cat 99 octan on the greedy kit im going with max 12psi or whatever my tuner says works best befor as you say it starts pushing hot air cheers

 

Make fun of the head gasket all you want. It may not be "the right way" to drop compression but, with the exception of a couple odd failures, it's proven.

Properly installed, the 3mm HG from Inline has proven a reliable way to drop CR and make good power with some level of margin of safety.

Ya, why aren't stepping in here? Tell these guys how far you've pushed this simple setup.
