how much timing
Im not questioning your guys tune, but rather mine. we run 26 on motor and 18 on a 150 and the plugs look good timing wise, seems normal right? thats why on my combo I would think 14-15 on a 250 would work good?
Every head is different but our motor likes 32-34.The nitrous tune is not always figgured on all cars out of base . We run ~20-22 on the 175 shot but we also have 2-3 degrees out of 2468 so thats 17-19 on them and 20-22 on the 1357. the evens run hotter on the ls1's. on both kits (~350) we run 10 degrees. again 7-8 on the evens.
we like the timing mark about 1/8 onto the strap in the 1/8 It would probably put it just to the bend in the 1/4 but for 1/4 we pull another 2 degrees from the 1/8 tunup to start.
