Most PSI on Boost Juice

I am going to buy the Stage2 Snow Performance Meth kit and I am going to use the boost juice with it, which is 49%meth and 51%water. What is the most PSI that I can run with my setup??

03 Evo VIII
Evo 9 Turbo
Megan TBE
eBay o2 Housing
BC 272s
IX BOV
PPi Ported Manifold
AMS FMIC
KN Drop In

I made 333/318 on a DynoJet and wanted to also know if it will be possible to hit 375 with the addition on meth. Comments welcome please.

The amount of boost applied will depend on the extent you go overboard on timing and the amount of fuel added to control knock.

Can't really state a good psi to use it will vary.

Try starting with 24 psi with less than 12:1 A:F and use the stock timing ROM with the load rescaled to 280%. Just fine tune the timing and use the boost to get the power

it all depends on the tune you will be running...find a good tuner and talk to him about your setup, he would be the best one to tell you how much boost you will be able to run

With 100% meth you can run btw. 29-32 psi... You need a good tuner though. With 50/50 I really don't know.

I would also use a heavier weight engine oil. I noticed after braking down my engine after 5,000 miles of running alot of Meth, i noticed alot of cylinder wear.

Look into a better oil to fight against this.
