We've run 24 lbs of boost with stock coils.



Post some specs. Turbo or supercharged what size, how much power. I've wondered what these motors can handle power wise, or how much a stock bottem end can take.



Mines a 392 cubed based off a 6.1 block. Offset ground the factory 6.1 crankshaft from the 3.58" stroke to a 3.795". Eagle Featherweight SB Chevy rods with Honda rod journals and .927" pin. Scary going from a 2.125" rod journal to a 1.88" with rods only rated to 500 hp, but after 400 passes the crank and rods are fine and going back in. Ross forged dished pistons, Ferrea extreme duty intake 2.08" int valves and inconal 1.62" exh valves. Hand ported and custom closed chamber 2005, 5.7 heads milled .021", .052" quench, 8.6:1 compression. Milled the heads for this build another .004" and brought the compression up to 9.1:1. 2005 5.7 coil packs still using the waste spark system, but bought 6.1 valve covers and will switch over to the 6.1 coil packs without the waste spark system. Paxton overdriven 1500 blower putting out 18 psi. 3800 stall, smallish cam, 216/220 @ .050" with a 114 LSA + 4. The new cam going in is a 219/225 @ .050" with a 114 LSA + 4. Still need the lowend tq to get my heavy azz 5184 lb 4x4 Hemi Ram out of the hole and let the blower do the rest. Best time to date with the old setup is a 1.48 60', 6.87 @ 98.xx mph in the 1/8 and 11.03 @ 118.xx in the 1/4.

As you can see, my 1/8 mi to 1/4 times are way off base. I'm thinking my stock coil packs where giving up the ghost as we have seen in the dyno room. I was hoping to try out Rich's new 6.1 coil packs the next time I go to the track to see if my truck will run the high ten #'s as it should.

BTW. I'm not a firm believer in Dynojet #'s. Heck its all over with in but a few seconds. I trust an engine dyno the most and then put it on a Mustang dyno for real world results as far as drive train loss. Better yet, hp to weight ratio with an E.T. slip.

Rich is on to a great product for all.
