| I have enjoyed converting my 924 to Delco EFI and would like to help others follow in the obvious benifits. |

| Gas mileage is of course good. The bueaty of the Delco system is its ability to constantly and emmediatley trim for an A/F air fuel ratio of 14.7:1 under cruise conditions. Most other after market ECU system dont have the sofistication that GM spent millions of dollars developing. |

Kris, Sorry I did not direct you to my porsch section on my web page.
Go to Current projects and click on Porsche supercharger installions photos. I dont have much data there on the EFI conversion. I also own the Toyota corolla running Delco with 24 lbs boost. |

| Supercharger on 924 is a Toyota SC14. I am getting 13.5 lbs boost and at present trying to purchase a intercooler as air temps are all ready reaching 125 deg C |

with a good IC you should be able to drop the temp by 50 deg

Kojab what kind of instrument did you use to measure air intake temperature? Or did you measure closer to the chamber, and if so, how?
I've been trying to locate one...
Thanks. |

Boost is going to drop slightly whether you have turbo or Supercharger.
I am expecting my 13.5 lbs to drop to 12 lbs.
The nice thing about the supercharger is that there is no boost lag. I have done logs which shows the boost climbs instantly with TPS. |

| Boost is maintained by the wastegate therefore a turbo engine can make up for the drop in temp. |
