how do guys run no alternators at the track and still hold 12v?

 

Two batteries connected in parallel, new or fully charged high amp batteries between rounds having to self start, no radiator fans, etc. Many ways to do it but not with street cars like his that are not setup to do so

 

it wasnt on purpose the belt flew off on a pass!!!

 

Gotcha. Thanks guys.

 

Christmas is coming early for a few people

 

 

Hell yea cant wait woot woot!!

 

Going to tune a car next week with a set of these. I fully expect them to do the same but I will post back with results

 

they use 16v batterys and charge them after every run

 

A little more from Tony

This is data from a batch of 100 of these injectors. This is flow deviation from injector to injector (every 10th injector was used for this test). The reason you see so much deviation down low is because of slightly different injector dead times from injector to injector. All our injectors are matched in sets based off of both flow and injector dead time. Make note, 2-3ms is where MOST of the life of the injector is, all idle and part throttle. Even with a good batch of current technology injectors, there can easily be a 5-10% difference in flow at low pulsewidths if the injectors are not matched in sets based on dead time. As you can imagine, 5-10% fuel flow difference from injector to injector at idle and part throttle can have a significant affect on how smooth an engine runs and also an affect on how lean you can run the engine



Here is the deviation data from a set of 4 that is properly matched based on dead time
