Things like different pulley combos for different boost requirements, intercooling options, injectors, exhaust (headers, high-flow cat etc.). Even the distinct possibility of launch control http://www.hymee.com/smilies/sm_nyuknyuk.gif. Cheers, Hymee. |

We have "improved" the design, to make it more packageable. Thats right, we haven't been sitting idle. The pics above show it mounted how we will run it on the engine dyno, and perhaps in the 808 wagon, but... When we go to install it in the RX-8, there is an issue or two. From my earlier pictures, you can probably tell there isn't much room behind the blower to bring the intake round between the blower and the firewall. Plus it is a long duct required. So are going to do something "special" if not unique. The blower will sit in the same overall position as the earlier engine bay photos (i.e under then engine cover etc), but it will be facing "back to front". The beauty of this is the throttle body will be now at the front of the blower, and there will be a nice staight path from the CAI and MAF tube to the TB and into the blower! The "complication" it introduces is that the blower drive is at the rear, not at the front. This means it is necessary to either run the blower off the flywheel (:eek:) or have a layshaft. So we will have a "long belt" at the front taking the drive from the front pulleys to the layshaft, and then the "baby belt" at the back taking the drive from the other end of the layshaft to the blower. This not really a new idea, I have seen it used sucessfully on the Chev LS1 PD blowers: (www.pwr.com.au) and (www.harrop.com.au) This introduced one other slight design challange, not really an issue with the "roots" style blowers on the LS1. The drive is in the wrong direction!!! So what we are going to do is have a "double sided" long belt at the front, and wrap it round the backside of one of the pulleys :) Pictures to come, stay tuned! Cheers, Hymee. |

I know I would be interested in a high octane map with cabin toggle switch if u get that far on the supercharger.

Whereas now, you don't really feel all that much cos the power comes on so gradually / smoothly. I doubt you'l ever see a renesis give you that sort of torque numbers :rolleyes: |

The torque gain exceeds the torque of a stock LS1 V8 but it just keeps on revving The Hymee car that I went in yesterday is very similar - probably more responsive as there was less lag and the thing just pulled very smoothly and strongly from standing still It was a much smoother and put the power down beautifully compared to My car which is a VY Holden Clubsport 5.7 litre 6 speed with 265rwKW The more load you put on it the more it pulled and it sounds very impressive (love the exhaust note) Thanks for the Ride Hymee, You are welcome to attend any LS1.com.au Cruises / track days anytime as that RX8 is definitely up to the front runner but with class,ride and handling :D Rod Ls1 Rocket |

I just noticed a mention on another FI thread about the insurance costs. Just to let you know, I rang my insurer before we drove the car for the first time with the compressor installed, to advise them of the mods. They noted that on my policy, and also advised there would not be any extra premium. I even told them the make/brand of the blower just to be a little bit more specific.
Cheers, Hymee. |
Who is your insurer?
Andrew |
Yes please tell. I think I will be needing them :D
|
I could tell you, but that would require them to sponsor me. Then I would need a Suncorp Metway sticker on my car as well.
Cheers, Hymee. |

Thank you Sir! ;) As you seem to be in a question answering mood this afternoon.... How's about a rough estimate for your blower :D :D :D |
any chance of having some type of by-pass system so at cruising conditions the blower would be making 0 boost which would eliminate most of the parasitic losses when you don't need the boost (and help gas milage)?

r0tor, good question.. and something that's already been considered. See this post: https://www.rx8club.com/showpost.php...23&postcount=3

ahh, I got to drive a kenne bell upgraded Mus.tang... very good indeed
definately are quality pieces, i know kenne bell is actually getting support from chrysl.er to figure out their fuel management for their upcomming HEMI kits since their eng.ine management makes ours look like a piece of cake (very overprotective speed density system) -...this p0st was edited for spam...- |

Cheers, Hymee. Mazda used Lysholm compressor on their Miller-cycle engines as this kind of engine needs a highly efficient compressor to give a fuel economy advantage over a standard Otto-cycle engine. Fabrice |

Cheers, Hymee. WOW... I just read all the information PDF's on their website. I am even more keen on your Supercharger kit now! |

It has stated in the modifications section "Auto Rota Compressor". Not too bad since I just read it over the phone to them. Should be "Autorotor". Oh well. That is what is it, the customs documents say so. Cheers, Hymee. |

I've just read the last 6-7 pages, and I'm blown away. Hymee will you be driving the FI RX8 to the Pre Nat meet at the Regatta on Sunday.
Keep up the excellent work and I'm certain you'll have plenty of buyers like myself. cheers, rx88er :) |
