Does anyone know if there is a manifold for a supercharged slant 6 225? I've seen a Chevy straight six with one and was just wondering if anyone could give me some info. It would be wonderful! Thanks Josh lovenlimp@hotmail.com |

Ok but I would like to stick with a carburator insted of fuel injection! can I get info on where you found the super charger so that I can look into this. The chevy that is in Chevy High Performance Magazine October 2002. 270ci straight six, has a rare after market manifold 4-71 supercharger 14lbs. of boost. It looks cool! Any type of info would be great, specialy where to get this stuff. Thanks lovenlimp@hotmail.com |

The blower is the Eaton M90 which was installed on Ford TBird Super Coupes, Buick Regals some GM products. Used ones are continualy available on eBay or rebuilt from Magnuson (see link). Are you thinking about a 'blow thru' or 'draw thru' setup? Depending on your design, if you stick with a carb, you may not need any manifold mods. http://www.magnusonproducts.com/m90_3rd_generation.htm ahtoews@shaw.ca |

Al T That is one badass slant, I have always wanted to modify my slant, looking at your endeavour, I now know that I cannot do it, I dont have the patience for that kinda deal, but nonetheless, you have got a very sweet piece of history, Congratulations. What was the total span of time that it took you, im also curious to see dyno results from it. Shed any light? Pete  Pyper70@aol.com |

Thx Pete I got the idea in March, started researching and buying parts in April, started building on the mule engine in May and worked full time on the real thing from the first week of Aug thru to the 23rd. Yes it was a lot of fun (I mean work if my wife is surfing these pages)! Dyno reults . . . I'm curious myself. I'm ironing out details this winter and probably look to get some performance numbers next summer. When I do, I'll let people know. Cheers! Al ahtoews@shaw.ca |

Al I would like to try that myself without the expense of the controls for EFI. Did you ever give any thought to just adding the Supercharger?If so what would be the best way to go.You have ONE OF A KIND with BIG RED,& the Web page is very well done allso.What would you suggest for the best Bang for the Buck,Draw or Blow thru.Useing the info on your web page & a little HELP it could be done.......Arthur coinjockey@webtv.net |

| Post subject: | Supercharging without EFI |
Arthur my intent was to build a daily driver that would have considerably more power when desired yet not sacrifice fuel economy over the broad range of driving conditions encountered. I never considered not adding PROGRAMABLE efi/ignition because I could not figure out how I could tune the system over such a broad range of variables using 'mechanical' means. My blower a positive displacement type and is activated by a vacuum activated bypass valve. It gradually closes off as the vacuum in the manifold dissapears. During this time, extra fuel is progressively added via the program to maintain the air/fuel ratio. As boost rises, I can gradually and steadily retard timing in order to preserve my stock pistons. My mixture knob can adjust fuel up to +/- 50% to quickly get things right and guide the fuel adjustments. My thots were that even if this could be done mechanically, it would take a very long time to get things calibrated correctly. I really can't offer much of an opinion on 'blow thru' or 'draw thru' since I have no experience on either. I think I'd lean towards a blow thru as it would minimize the amount of 'wet' plumbing. From a tuning perspective, you'd then adjust the carb/timing in a similar manner to what Andrew, Tom and the other turbo guys are doing. They're forcing in more air thru the carb using exhaust power. You'd be doing it using crankshaft power. For what its worth . . . Cheers! Al PS. Certainly an advantage of the 'dry' manifold of MPFI is that fuel distribution problems due to inertia, boundaries and temp variation are eliminated. ahtoews@shaw.ca |

Anyone who has ever done a project anything like this realizes how amazing it is that you completed it in such a short time. Congratulations! I don't know how you did it. Did you keep track of the total cost of everything needed for the EFI conversion and supercharger? Bob D BBobbias@aol.com |

| Post subject: | Time and Costs |
Thx Bob. Coming from someone who's gone down this kinda path before certainly makes the feedback more relevant. I read your article on EFI about 5 times before I decieded to move ahead. It was very valuable. I did sink a whole lot of hours into this project. It became an obsession, especially during the month of August as I was getting close and the big question lurked in my mind,"Would it actually run? Had I missed something big?" I did keep track of approx costs which I've converted to $US. I spent $500 for my blower (eBay) which included the entire induction system for a 90 Tbird SC (airbox/MAF/intake tubes/throttle body/blower inlet tube/blower/blower to intercooler tube/intercooler/tube to intake manifold/Ford 3.8 intake manifold & some misc FI tubing) My programmable SDS FI system along with distributor less ignition, all sensors and Bosch hi press fuel pump ran about $1800 My fuel rail & Accel injectors and rest on the pieces for the high pressure fuel system ran $3-400 Then there were the many little costs like chose to incur (steel flex hoses, Earls fittings 'robbery', filters, fluids, gaskets, wrecking yard parts, etc) I almost forgot the cost of the aluminum manifold mod costs ($400) Total probably somewhere between $3100 and $3800. Not cheap but would I do it again? You bet! Cheers! Al ahtoews@shaw.ca |
