John,I wonder if you could give some details on how your turbo engine is put together--size,cam type,stock or aftermarket cases and crank.Brian was a little worried about engine life span as we neared 160 RWHP.So I will have to upgrade stuff for next year. Thanks for all the tips,finally got it narrowed down to fuel feed.I hooked another hose from plenum to fuel bowl,raised needle all the way and shimmed it,and opened up float needle seat with jet drill a little--also float level was off. |

Firemanjim, I installed H2O injection , Aquamist, neat stuff. Look up some of my old posts. Is the shop kind of messy? I need input on the build up.I'm reconfiguring the Aerocharger, different compressor wheel and diff turbine housing. Thats about all I have started. I need cam ideas,roller rockers? crankshaft work? carrillo rods?I want to run at 7500 RPM. I'm thinking 9 to 1 cr. With H2O and a intercooler maybe more? Different drive pulleys? |

What kind of HP are you shooting for?Definitely go with rods and roller rockers,probably cases,and crankshaft,cams I know nothing about,except the normal hot cams are wrong for a turbo.How much boost are you going to get with rework? |

I don't know for sure FMJ, but I'd say he is going for 125 to 145 HP. Jim - I think 9:1 for a static compression ratio is probably to much, if you really want to crank up the boost. Aerocharger told me 8:1 and I went to 8.25:1. Stock S2 cams, stock t-storm heads, 8.25:1 CR, and 15 pounds of boost should take you to well over 125 HP at 6KRPM. If you want 125 to 145 HP you can make it for much less money than you can make 125 to 145 HP with a 7,500 RPM redline. It's that RPM, to much changing direction, that will cause you to spend the $ on the internal parts. JMHO |

Jim M, Every time I see your bike you are doing something new to it. Damn dude, have you even put 500 miles on it since you bought it? Just ride it and enjoy it this summer. Once winter hits rip it apart and go for the big numbers. |

Jim,Brian Nallin told me that with that much HP I need to worry about the stock cases deforming.Going to look at S&S, etc.Stock crank is pressed together and will do same.Remember the stock Sportster engine(our engine) only puts out about 59-60 something HP stock,and we are looking at 2-3x that. |

Vr,turbo is still the way to get most power for dollar spent.Keep engine docile with lowered compression and turbo spec type cams and don't shoot for stratospheric HP #'s.I did big inch motor last go around,and turbo was less money,especially cause I got it second hand.I think most of my problems stem from fact I am sticking it on that same big inch motor--and I am turbo ignorant!!From watching #'s from Roc's stock S-2 he was pulling more HP than my big inch motor last year at Aaron's.And not yet running as good as it could. |

Vr,last year 88" motor done by Nallin with stepped open pipes made 121 hp.(My own fault as I went conservative against Brian's recommendations)Roc's bike was making about 125 last year.So a stock S-2 with turbo made more than the big bore,cammed,ballanced,etc. bike.Now its making 156 and has the potential for a bunch more. |

Nope,did not change anything,still have Redshift cams ,and high compression relative to a turbo,so I have limited boost and timing,and high octane race gas.Wanted to sort out turbo first and that took quite awhile.Next year we juggle pistons,etc for more power. |

Everyone around me says I should just buy a 'Busa and be done with it.But what's the challenge in that? The "challenge" is the essence of the multi- million dollar aftermarket go fast Harley(and Buell) industry. Its the underdog frame of mind,I quess.

If I'm wrong tell me but Eric Buell's philosophy is total balance of the motorcycle. Politically Correct Motorcycle Engineering. Too bad, but thats what the aftermarket makes up for.Its time to be outrageous! Unfortunately there is no way I could afford it! There has to be someone ,Jay Leno? Because there are components to assemble such a motor and given there could be a way to use the basic geomerty of the Buell, should we just discount it? |

Vr,I read through a bunch of your posts.Are you running the Mikuni carb?Thats where I had alot of my fuel feed problems.Float was low,needle needed to be shimmed,running a 200(I think) main jet,and the needle and seat set-up that Aerocharger has in them is a very small one because of electric fuel pump pressure,and I opened this up a little as all of my problems showed up at full throttle/high boost conditions.I also had to turn up fuel pressure almost to the point of overwhelming the needle and seat to get it to run better --- to the point it was flooding until I dialed it back a touch.Each of these things contributed to improving high rpm running.Your boost controller has two set screws on it,one on either end,one limits travel of piston the other changes spring pressure.You can fiddle with these to try and get more boost.I was seeing over 16 at first and am now at about 9-10.I was told Buell system stock setting was 11.5 max.Also newer style plenum supposed to make more power with less boost.Remeber that these were made to fit stock Buells,so fuel feed set-up and rpm range they were to be run in not like our bikes.I gapped down plugs like Roc and it ran better . |
