    Thinking of something weird... So I feel like e85 is going out of the picture... E85 is leaving stations left and right because now it's 3.40 a gallon. Remember when it was 1.20??

    Now... Matt would say... "Why not do methanol injection then?" And I agree. Great idea.

    But... No one does N2O on WRXs. A simple 50shot with Q16 at 22psi? I would be able to do something kinda new and definitely different. Plus, I can refill it where I work. Don't know if I'd get a discount... But it'd be nice!

    So... Q16 would give me the detonation resistance of e85... It'd be a lot more consistent... And it'd give me more fuel pump and injector headroom than e85 currently does.


    With that additional headroom... It'd be enough pump for the additional fuel injection for the wet nozzle.

    And let's be honest 50shot isn't really that much.

    You know me well

    Meth injection, when paired with proper failsafes, is great.

    When I do my build, I'll be running pump+meth. However, mine will not be an aggressive map. It will be a map utilizing meth more for knock control than for power; the goal for using meth is to run a setup that will never knock (regardless of gas quality).

    You're correct, people don't typically run NOS on Subarus. Personally, I'd rather not pioneer anything with my car.

    If I were in your shoes, I'd go with Q16 for the track and 91+meth for the street. Don't tune the street map too aggressively, and your build should last "forever".

    There are a few on nasioc and 1 on iwsti that have successfully used n2o... And I have yet to find a "I did nos and blew my STi" thread.

    This isn't exactly a pioneer of a car, but I don't know anyone with 25-22psi on a Dom1.5xtr turbo with a TMIC... I don't usually follow the masses. I also had 400whp on a stock catback not long ago. . I do try and be different somewhat. And honestly, n2o is a lot safer than F&F makes it seem. It's just another power adder which adds oxygen... And the wet shot kits meter the fuel so you don't have to. Only concern is making sure you have a throttle switch so it turns off when off the throttle.

    I'm not saying I'm doing it... Just thinking about it. I still have to get coilovers, and new brakes first.

    There are a few. However, I still wouldn't do it myself.

    You made decent power on the STI catback, but you'd have made better power. Similar to your stance on cams; just because you can make the power, doesn't mean you can't make more / do it more efficiently

    Actually... I removed the STi catback and put an aftermarket one on (custom 3" with borla muffler) and had it touched up by Harvey (at the time) and I didn't make any more power with any more spool. I still contend that the stock catback is good at 400whp

    The only thing I'd like to add to the discussion is to consider your engine build if you are changing any of the topics of interest here.

    I think one of the best advantages of e85 is that it is there 100% of the rpm/load range - meaning you can run a higher compression piston and still get your optimum timing.

    With any 'additive' type system, you normally only use it in the heavier map areas. While that is the general idea (keep it from blowing way up high)... you may not be able to get some of the daily driving perks of running a higher compression piston and still hitting your timing on the dot.

    Aside from that, Kevin, n2o is functionally another method of forced induction (as you hinted at). Whether it's worth it for what you get, that's your call. I like the idea but don't know that it is appropriate.

    I have a feeling you'll be pushing the turbine side (and hence exhaust bottle neck) of the 1.5XTR pretty hard with the n2o in this situation. I'd consider meth injection in your shoes.

    FWIW - your build is very similar to what I'm aiming for with my build. That Dom1.5 seems down right impressive and perfect for daily driving.

    You can always have 2 maps... one for N2O and racing, and the other a daily. Which makes the most sense because I wouldn't be driving on Q16... right?

    As far as the turbine side... I did a 10cm housing instead of the 8 which is usually seen on most of the 3071's that WRX owners pick up... I can't imagine a problem with it being too small

    She's running and driving well... Cold starts under 40 degrees are a bish. I'm going to fiddle with stuff in the tune.

    For all of you thinking about doing an aftermarket fuel rail... Rethink using oeteker clamps. They suck. I have yet another fuel leak. It seems like as soon as it gets colder and colder the rubber hoses shrink and I have more problems.

    Now my shifter is starting to vibrate more... I need to look into that.

    I just got front brakes. I'll do those either tomorrow or the next day.

    Re: Sinister's Progress Thread

    What would you suggest for fuel line clamps? That's good information to avoid those though.

    My last book suggested always pressurizing the fuel system before starting the engine to verify the system holds after any fuel system changes. If it's happening due to temp changes though.. That's pretty annoying.

    I was saying the turbine would hold you back with n2o I think. Adding an additional form of forced induction basically creates a mismatched turbo if the other form is significant to my understanding. It would still work... Just a trade off to consider. I'd have to touch up on my brocharging/n2o to tell ya more confidently

    What brakes ya get?

    I did check that. It didn't happen before it got cold.

    Heide... Look up the chaos series in drag racing. Huge Turbo and Supercharged V8 engines with big bottles of nitrous. They're so powerful they only let them go the 1/8th mile.

    I got stoptechs and powerslots (based on price)

    Hate!

    We got my coworkers taken care of on a normal drill press with a bit of a creative clamp. What a stupid idea to not use a steel insert in those.

    I looked and it sounds like a series that's only at bandimere and pueblo. The chaos cars are running a 6 to low 5 second 1/8th mile. Anything goes as far as turbo blowers and nitrous. There can't be a tube chassis (back half tubbing allowed), and the max tire width are 10.5 slicks. There are weight limits placed on each class.

    These are cars that scare the piss out of me. We're talking full bodied cars with 114mm turbos on v8s with two nitrous bottles hooked up. It's no wonder they only allow 1/8ths on these things.
