ggzilla Posted March 7, 2014 Report Share Posted March 7, 2014 With a crankfire, the L20B will make 110 HP. Quote Link to comment
RTB Posted March 7, 2014 Author Report Share Posted March 7, 2014 I thought that was the stock figure for a l20b Quote Link to comment
ggzilla Posted March 7, 2014 Report Share Posted March 7, 2014 It is. Crankfire will not increase your HP, but it is more reliable than points. It will also give a steadier idle. Quote Link to comment
RTB Posted March 7, 2014 Author Report Share Posted March 7, 2014 Right but will it perform a lot better than a matchbox? I just have trouble believing that BRE could run single points in their race cars in the day and push those engines very hard yet a more advanced matchbox cant handle more than 7k?

ggzilla Posted March 7, 2014 Report Share Posted March 7, 2014 Crankfire won't perform a lot better than a matchbox. Its main advantage is tuneabilty via laptop. To tune a distributor it may be recurved which needs no computer. Matchbox will exceed 8500 rpm on a 4-cyl. Datsun guaranteed it to 7000 rpm on a six-cylinder. Quote Link to comment

smoke Posted March 9, 2014 Report Share Posted March 9, 2014 Not that I am advocating the use of single point on a high rpm engine or anything, but I thought I should mention that point bounce at high rpm was primary a topic amongst V8 guys. This is due to the points having to open and close twice as much than on your engine. The points needing to come back to a rest with the cam lobs of the distributor so close together is much harder for them to do at high rpm than on a on something with half as many lobes. So guys with 4 cylinder engines, with good points that are set correctly, could really wring the rpm out of them before having any bouncing issues. Quote Link to comment
metalmonkey47 Posted March 9, 2014 Report Share Posted March 9, 2014 Are they different rod bolts than the standard l20 ones? I thought you had to upgrade to something like small block bolts. I have ARP big block Chevy 3/8th rod bolts in my lz Quote Link to comment
