Aux fuel? Stock fuel pump? Upgraded HPFP? Do you have any of these? Are you referring to whp or hp?

I could see maybe 350whp but that's about it. You would need 4 port or a new HPFP and injectors to get above that safely*

I made 280whp with an S280 without water/meth. When I ran the meth I made 320whp, and that was about the limit of the stock fuel system. I was running a 50/50 mix (or probably a 49/51) so it wasn't really for fueling purposes and I did not want the car to be totally dependent on the meth as a fuel source.

A car I help put together did 326whp and 340wtq on pump 93oct and meth. Stock Map sensor and kept at around 28psi~ maybe with aux could've gotten to 340whp but we wont know for a while.

Edit: This was in tropical weather and a ambient of around 92-95*

What mix? A guy locally is considering trading me his meth kit for my 2J.

370whp is already pushing the s280 very hard, you would need to be around 33-34 psi for that power level. I suggest thinking about either a larger turbo or something more realistic for that turbo which is around 330-340whp at 30-31 psi.

Edit- this is regardless of fueling
As someone already running 33-35 psi on an S280 with aux, would I see any gain from water meth? Would be nice to have a little extra sauce at the dragstrip.

Add it and tell us! I wish someone like alkycontrol made a true kit for our cars. Running 100% would be fun.
