I think it'd be an awesome way to go about it. Talk about full control over the system.
It would be more expensive, but it would also be a much better system. It's all relative though. Cost is important to me, but it's not the first thing I think of when making choices for parts. Reliability, and function comes before cost in my eyes. But it's a give take of course.

IMHO, meth is terrible.. too many variables. If you want that much power put race gas in it. You'll still have a motor next year.
If you just use normal jets the meth will be sucked in by manifold vacuum.
Also if you are using an aem or something similar you can wire one of the spare injector drivers to a solid state relay and use that to control the meth pump so that you can easily tune the amount of meth delivered. Wire the negative side of the relay to the injector output, wire the 12v side to a HS output on the ems so that you can turn it on above whatever boost/tps/rpm you want.
I'm not sure if it would work but depending on the size of the line feeding the system you could wire a nitrous soleniod to the HS output as well. That way the vac in the manifold cant suck the meth down when you dont want it to.

I think I'm being careful this time around. Dropped compression/direct port/flow sensor/etc/etc.
I'm not looking to drive around making max power all the time. I typically drive @ wastegate anyway, then if I want to turn it up, I can do so. I only run max boost @ the track though, and that is maybe once or twice a yr.
I do agree with your comment thought, if this were an all out race car, I'd stick with race gas.

if you only run high boost at the track the meth REALLY doesnt make any since at all, other than to say you did it.
For minimal high boost use race gas should really be the only option. Less shit to buy, less shit to break and WAYYYY safer.
You do realize that if you build a low compression motor you can make 550 on pump gas pretty much all day long right? The tranny is going to give up much past that.

To make 700whp+, I really need another pump/fittings/etc. Regulator or swap to bigger injectors. It's $$ either way.
Not to mention I don't have an option to buy (116) race gas, it's 2 hrs away from me. Best I can buy locally is 110.
I've done the race gas route on my old setup (pre-s2k), and it was a pain. Going out an evening and want to play around, oh wait I can't I don't have race gas.
Next weekend, go out and put race gas in, nothing happens, just wasted 50 bucks. Tired of that. I want the flexibility methanol provides, and I believe this setup w/do just that.
I'm not arguing w/you, just offering insight on my decision. I value your opinion.
racegas > methanol
However in my situation, it doesn't work out that easy.

110 is plenty, you can make 700hp no problem on that and most places can/will ship/deliver it to you.
we dont have anyone local that sells race gas either, a distributor that around 200miles away delivers it.
put some of the -11cc mahle pistons in your motor, make 550 on pump gas, then when you goto the track put the 110 in, turn it up you have 700.
I havent ever been in a 700hp s2000, but from my last experience, 500 was more than enough on the street.. haha

I'm not made of $$, so delivering gas isn't going to happen either. I don't trust the consistency of our 110, it's in a tank all year, no telling if it's even 110. Although it does smell nice, lol.
The motor is built and sleeved already, I'm using my direct port setup.
I'm not going to re-do my setup, and add even more complexity to the setup with added pumps, bigger injectors/etc, not to mention more money involved.
Something about rolling around and being @ 500whp, and then cranking it up w/o worrying about race gas, where to come up with it, and wasting money if I don't use it. Not to mention you have to always be cautious about filling up, I could only run less than 1/2 tank, b/c I didn't want to dilute the gas, draining your tank, just to much of a hassle for a street car.
I think you made your point.
