How big of a wet shot

FastRegalWE2 · 02-01-2007, 09:42 PM

I want to try taking off the alky and going more to a track style set up with race gas and nitrous. I think the engine should be able to handle at least a 200 wet shot but I figured Id ask in here. The engine is girdled and all forged with a TH400, but its the nitrous reaction with the higher cylinder pressures I dont know anything about. I have FAST, T70, all forged roller, 83#, etc etc.

Some of the Pro Mod guys use a 800hp hit on a motor with 15:1 compression.Just like with the turbo, its all in the tune up. A safe starting point is 3 degrees ignition retard for every 50 hp of nitrous. A timing retard device like Jacobs Nitrous Mastermind or Timing Retard from MSD is a good tool for this. They only pull timing when the nitrous solenoids open so the car runs better when off of the spray. I ran this way for years when I was a n2o junkie.HTH

What has worked really well for me is around a 100hp shot.

I use all Cheater system components, and run through a single fogger nozzle.

Nitrous jet is a #46
Fuel jet is a #42

Depending on boost levels, it's good for approx 100hp at the rear wheels.

Depending on your FAST system, you should be able to activate the nitrous and have a seperate timing table for the nitrous.

Things to consider are

boost level- Nitrous will give you a bump in boost. 50hp 1-2lbs
timing- I have retarded 2 degree for every 50hp
Traction- 100-200 off the line will challenger your traction
Progressive control- again depending on your FAST system you might be able to bring it in form say 25% to 100% over 2 seconds
Plugs- run a little colder plug and check them (best way to tune the nitrous)

Hope that helps

just looked in my FAST program, there are places to input nitrous info, may just be able to do this
