    Scared of nitrous and what it might do to your engine? Don't be. Nitrous is one of the most incredible power adders there is. Misuse of nitrous is what makes people scared. But if you're still not ready for nitrous on your turbo engine, here's another option: a nitrous spraybar mounted in front of your intercooler....

  2. so lemme get this straight, the nitrous doesnt actually go into the engine, its just sprayed on the intercooler to cool it further?
     
  3. Yup...and for nitrous kits going into the engine, there are plenty of safety precautions (eg. RPM windows, A/F ratio shutoff, etc.) one can take that are optional for most of todays kits. Today's nitorus kits are about as safe as you can get.
     
  4. As long as you can read the directions. <A BORDER="0" HREF="http://www.supercars.net/PitLane?displayFAQ=y"><IMG BORDER="0" SRC="pitlane/emoticons/wink.gif"></A>
     
  5. there safe, but thats not what I would be worried about.

    The part that sucks is the horrible wear and tear on your engine.
     
  6. It's not horrible wear and tear if you install everything correctly, and use the appropriate nitrous kit for your application. It won't wear your engine any more than if you use a supercharger or turbocharger; the advantage is that you can turn nitrous on or off, in most cases you can't do that with a blower or turbo.
     
  7. I just thought this was a really cool idea, considering that Honda got a (66hp?) inscrease thanks to this.
     
  8. At 25psi I imageine it would help a ton, considering how much air is going through the IC and how much pressure drop there could be potentially.

    On a side note, how the hell do these engines make so much power on small turbos? They call a GT35R "massive", but on most RX-7s it falls on its face after 22psi and can't make more than ~470rwhp, yet it can make 700+hp on this Civic and 800+ on the AMS evo.
     
  9. Rotary's arent exacly the best for high PSI i dont think
     
  10. This is old..........also Rotary engines take boost just as well as a piston engine.......you just have to keep watch on it a lot more then some.
     
  11. I don't know, but there are MR2 guys running it at about 25psi and making around 550rwhp. There are also guys running it making considerably less. The only other GT series turbo I know of making huge power on MR2s is a GT4245r at 33psi which made just over 800rwhp.
     
  12. That's what I have been trying to tell people for years, but no one ever believes me.
     
  13. these coolers have been around for awhile now, there is a company that this is all they make Ntercooler or something along those lines, but with those you can use CO2 instead of nitrous to cool with, same results, not wasting nitrous that could be going into your engine, and i would think CO2 would be cheaper/easier to get than nitrous.
     
  14. Nitrious eXpress makes the Ntercooler. NOS makes same shit but I forget what they call it. Its just a damn thin small tube of metal with holes in it that spary nitrious right on the bars of the intercooler. BUT you should only do it when its stopped because when you're car is in motion this shit is worthless to spray.

    Again this stuff is old. Its been around for about three or so years and before that people have been hooking shit up that they bought form the lawn and gardan places so a nice stream of water can be sprayed onto the intercooler.
     
  15. That AMS EVO used a 42... I think. 35r is massive. 20 psi at 5k on a 1.8 VW.

    And isn't your rotary 1.3l?

    I think if I went a bit bigger then mine 3071r, and C16 I could easily hit 470 wheel. A T3/T4 with a stg.V wheel should do that too. You rotary guys suck <A BORDER="0" HREF="http://www.supercars.net/PitLane?displayFAQ=y"><IMG BORDER="0" SRC="pitlane/emoticons/tongue.gif"></A>
     
  16. Off topic, but I ended up going with a (used) Precision SC44. I just paid for it yesterday and it's supposed to ship today. It's used, but it's supposedly in great condition and it was pretty cheap. I'm going to clean it up, polish the compressor housing, coat the turbine housing and check it out in general. Should be good as new. I'm probalby going to cover everything but the compressor housing with a shield anyway.
     
  17. How do you guys polish the compressors? I tried to do mine but failed. Sandpaper couldn't get in all the lil spots. Someone told me they just used one steel wool fitting on their power tool thingie. (Forgot the name.....used to drive in screws I think lol).

    And how big is an SC44? I see those names throw around a lot, but I don't know who makes them and how big they are.
     
  18. I've never actually done it. I'd assume it's pretty much the same as polishing anything else. A wire wheel on a drill/Dremel, then a polishing wheel with polishing compound.

    The SC44 is about the same as a T3/T4 60 trim. Supposedly good for about 565hp (though, I won't be pushing it near that high).
     
  19. 60 trim is biig lol.

    Yea, I tried to do mine with sand paper. Bad idea. I might be switching manifolds in the summer, so while it's off, I might give it another try.

    How many psi are you going to run and by what RPM do you expect them?

    And I just figured out my car feels slow in 2nd gear is because the tires completely break loose <A BORDER="0" HREF="http://www.supercars.net/PitLane?displayFAQ=y"><IMG BORDER="0" SRC="pitlane/emoticons/tongue.gif"></A> . 30F will do that to summer tires. <A BORDER="0" HREF="http://www.supercars.net/PitLane?displayFAQ=y"><IMG BORDER="0" SRC="pitlane/emoticons/sad.gif"></A>

    I'm not really sure what I'll run. I'd guess between 18-25psi (380-450whp?) and should hit full boost by just over 4k (so I've heard). The coldest it really gets around here is something like 50*F and as you know, I'm going to be running 315mm DOT slicks, so traction shouldn't be a huge problem.

    As for polishing, after my previous post I searched it and came up with these:

    I've seen a 57 trim push 20psi at 4k on a dyno run, while my GT3071r goes to 4k at like 4,200-4,300 on the street. Maybe break in time?
     
  22. Whats wrong with going big<A BORDER="0" HREF="http://www.supercars.net/PitLane?displayFAQ=y"><IMG BORDER="0" SRC="pitlane/emoticons/tongue.gif"></A>

    Once I save up to around 10k i'll be going with a GT40RS
     
  23. What car?
     
  24. His MKIV Supra?
