Not being real familiar with the viper cdi is it possible to reprogram it to not have that sprike at 8200-8500 rpm? Not looking at using a srx cdi at this time just wonderin what can be done with the stock one. Thanks!

You can clutch the sled to run at an rpm that is not inside of the "hot" range.

nothing you can do, cant be reprogrammed. the srx cdi thing has been talked about, i have a complete srx cdi and the jumper wires (thanks betheviper) and all the directions to make it work. i was going to do a bunch of runs on the dyno with both, to see the power difference (because you will lose some with the srx box) but after mine ran so well this year, no problems, ran very strong, decent mileage, ect... i opted not to fix what wasnt broken. my .02 ski

eric did you run the stock head with those slps?

no, too many burn downs seen on here. i added a roof tunnel cooler,& megapower heads for better cooling (and i run water wetter) i run br9ecs plugs and premium for security also. i think this is where many people miss the boat on the vipers. the srx's have to run premium and ecs plugs with a looser (if you will) squish band than the stock viper. so why would you expect a viper motor to survive without giving it the same or better protection as the srx? my .02 ski
I'll be running the same thing since he has her dialed in and working like it should, thanks again for the help ski!

how does that water wetter work? I have always wondered about that stuff.
I haven't used it in the sled yet, but my modified car it reduced the coolant temps by 10 degrees, and helped me avoid upgrading the radiator. Its good stuff.

No glycol in water wetter so don't plan on using it in the winter.

water wetting reduces the surface tension of your coolant, meaning that it is able to transfer heat better. meaning your heat exchangers and your motor are closer to the same temperature.
here's some info on the topic

as far as using it in the winter, it's fine to, just measure the water wetter volume as part of the "water" portion of your mix, and use the same glycol portion you would normally use and your mix will be the same strength as it would have been otherwise.

Put a 4* timing key in facing so it retards the timing. It will cost you HP but will also get rid of some heat.

Yea i thought you could use that stuff in winter, might have to try it out. Cheaper than another exchanger
