Pretty much, It may make a bit less because it would be low comp. ________________________________________ Ex SC-6Now in a Megane R26 |

I guess that when you are running the high boost in you just run with the low boost injectors/map then upgrade when you are ready for mapping. Hopefully zac or rich or someone will come along soon and will tell you. I am only guessing. ________________________________________ Ex SC-6Now in a Megane R26 |

What injectors are you using? 440 ccs? as said you are running low compression for which there is no low boost map available. You could switch to a low boost map but as you are running ~9:1 compression as opposed to ~10.8:1 standard it might be a little sluggish. |

im going to be running about 230ish i think as going low comp but staying low boost for now, low boost map will be fine as thats what rich has done for mine. i will go for larger injectors and larger boost pipe and cooler, although i might get rich to do me a diff map, and diff restrictor so i can run at 280ish safely, to be honest i just want to run again!________________________________________ In my garage just now2003 BMW M3 & 2009 L200 Raging Bull & Audi Q5 S Line AX stock rod & Saxo Stock rod Sold the bike an charged rallye an bought a caravan, midlife crisis or what! |

I don't understand why you would want to only run 'low' boost when you have done the extra work required to go 'high' boost  If i had gone to the effort of changing the pistons and rods and bearings etc, and have the larger boost pipework then I certainly would be running without the restrictor ring! If you only want 250~ bhp then dont spend the extra money on the bits not needed! ________________________________________ Long live the Sigma 6 Team Phase 1 supercharged XBL ID: farmer uk1 |
