    20bt S2 Rx7

    Never really posted this up before. Has kinda been a little ongoing project of mine for the last couple of years. Done most of the work myself - Now its nearly at the stage where I'll let people have a look. I cant let you know all my secrets but lets just say I'm looking forward to debut at next years summer nats Dyno comp.

    Enjoy! :D

    whoa... methanol?
    why no intercooler?

      yeah ran a 10' PWR water to air intercooler. found it a little restricting down low seeing as though the exhaust housing is pretty big. So i ripped it off and decided to go methanol injection along the compression pipe and water injection through the turbo. has gained a few ponies. not to say the Water to Air wasn't good just the turbo is quite large.

        I see! is that legal (to HP Heroes rules)?

        btw, are you injector methanol by engine load or rpm? and what are you using to inject it?

          Using mercedes benz injectors that are methanol safe. boost actuated not rpm. even without methanol injection I do believe that sumernats allow water injection which is quite ok to still do an impressive dyno run on pump fuel..

            Cool, what is different about them that makes them methanol safe? I presume they might even be water safe.

                They're stailess steel injectors with a special neoprene seal. and yes they are water safe also.

                  Nice, do you recall which model car they were from? do you have any other specification like flow, impedance, etc. Was the neoprene seal fitted yourself?

                    Thanks for the kind words. I really don't know if i will. I kinda like the idea of plodding along quietly and rolling up fairly unknown.

                        Actually I really don't know. A cluey friend of mine informed me of them and suggested that they would be perfect to run off a couple of mt2 computers. So we just made up a rail and put them in. and then went to the dyno to tune the feed.

                        I could try to find out for you though.

                          third, forth and fifth. I think the box might be the next thing to go though. Series 5 won't hold up long if I get some decent tyres

                            I'd appreciate that if it isn't too much trouble.
                            I've never actually tested an injector with water or methanol but 'they' say that the injector will rust or sieze.

                              thats because most are mild steel. they also have rubber seals which deteriorate with methanol. I'll ask my friend later on in the week when I see him next.
