well i have no access to ethanol so its out of the equation unfortunately...
meth is available but its a one hour drive roundtrip for me to get it and since i live in an apartment there is no place to store it..

truth is... i am just trying to piece together all the info i can find as i am trying to justify whether a set of upgraded twins would be useful if all i can run is 93 pump... thats all

from a financial perspective... it doesn't make sense to fork out 3000+ usd for let say... a set of Pure S2 DDs if all i can get is 400-450whp due to limitations on my side...i may as well replace with a pair of stock turbos or S1 and put the extra $$ elsewhere
Order boost juice have it delivered to your house. You'll be able to get low to mid 500's out of the stage 2's on just pump. But as I said just order boost juice and store it in your closet, under the sink wherever. Doesn't take much room.

Plus remember dyno numbers don't mean everything. First... peak is peak... it's power under the curve you want. Upgraded turbos with supporting mods will give you a LOT more area under the curve. The car will pull to redline significantly differently than before, even on pump gas. It really can make the car feel like a different vehicle.

If you want big power in pump either go with the GC or 62mm+ single. Andy made 600whp on just stage 2 LPFP and stock hpfp with his 6266 turbo kit.

To the guys who had some experience with just LPFP Upgrade and Stage 2 Turbos:

What was the rail pressure you were seeing?
I am running TTE Turbos at approx. 25PSI, but my rail pressure and trims are maxed out. I am running 102 Octane..Should be around 550HP. I do not need more Power although the Turbos have a lot more room (45% WGDC), but i would like to know what are the safe limits on the stock fuel system. I think running on the limits of pressures is an game with the devil... My Rail Pressure goes sometimes down to something like 900 and then backs up to 1100-1300...

Where did you see this? Do you have the dyno sheet by chance?
