Eliminates the distributor and plug wires (always trying to clean up a crowded engine bay) , plus picked up a couple of hp and lbs-ft using copper plugs instead of the platinum ones. Before and after pictures included, plus a dyno chart of stock with a .051 plug gap on platinum plugs (run 50), stock with a .060 gap (51), then COP with copper plugs at a .060 gap (59). Nothing like adding lightness (to the car and my wallet at a mathematically related pace-go figure!). Thanks to Mike Trendel, who said he might be coerced into making a few more, if anyone's interested.
Btw, if the graph looks a little different than my last one seen here, I think it's because the cam timing might be a little off. We replaced the stock oil pump with one of CFM's billet aluminum geared ones, and my torque and hp bubble at 5000 rpm has gone (this is the first time I've been on the dyno since before the new pump. The oil pressure is higher with the new pump, as much as 2 bar. The only 2 culprits would seem to be oil pressure or cam timing, and most people I've spoken with discount oil pressure as the perpetrator. Any thoughts would be welcome.
Hey, I hijacked my own thread! 0-full thread drift at R500 speed!!
The oil pressure WAS the culprit. Excess pressure was preventing the VCT from operating properly, costing me my torque peak. As soon as the stock pump was installed, the proper power curve returned. Hooray!
