But the campaignâs swift rise hinted that maybe the chronically second-place Indiegogo was finally catching up to the crowdfunding gold standard, Kickstarter. Indiegogo was founded in 2007; Kickstarter didnât come along until 2009. The former has hosted 1.3 times as many completed projects as the latter.
Universal cooling system pressure tester that eliminates the need for almost all system adaptors. Complete with 4 double-ended cap adaptors allowing 8 different caps to be tested. Universal cooling system pressure tester that eliminates the need for almost all system adaptors.
Radiator Caps. In a cooling system, a higher pressure equates to a higher boiling point for the coolant. Higher coolant pressures also transfer heat from the cylinder heads more efficiently. We recommend using a radiator cap with the highest pressure rating that the radiator is designed to accept. In general, performance radiators will accept 22-24 PSI, and professional racing radiators will accept a 29-31 PSI. The coolant will typically only build to 16-18 PSI, due to expansion up to 200Â°F.
