What If Build Ideas...for Land Speed Racing

Your NA inlet temp is low for Bonneville. Common to see 105°F there, which is more like 40°C.
Weight is your friend on the salt.
To run boost, use a boost retard coupled through a Bosch relay. Power the boost retard off the 87a terminal. This will retard the timing on startup. Use a boost switch or vacuum switch to energize the 85/86 control circuit of the relay when vacuum drops or boost comes up and just before detonation would be a problem. This then shuts off the timing retard as the relay switches power to the 87 terminal. Power water injection with that. You can get away with a bit leaner mixture, but you need 2° to 5° more advance with water. Start with 2°. The amount of retard is programmed into the box. Set your timing with the relay energized.
Also remember Bonneville is fairly high. They do post weather conditions with density altitude condition for tuning.
Thanks. Yes it was a formula based on here in WI or at least generic and all temps would be required to be filled in based on your location.
