408 nitrous?

[top flight]

Just finished my all forged 408 and want to know how big a shot I can spray?

That depends completely on your build specs, but if it is fully forged and built for a big shot you might be able to go upwards of 400. If it isn't built for spray you are prolly safe with a 200 shot. Tons of variables to account for.
The most important thing is the tune in most cases. Also remember with a big shot you are going to need more supporting mods than just a built motor. Be prepared to break stuff.

Its fully forged and speced for a big shot from Texas speed with patriot stage 3 heads 240/248 cam 11:1 compression and stage 5 finish line tranny 4000 stall 4.30 gears with moser axles! And I'm thinking a 300 shot!

Good tune up, forged motor, spray as much as you want.

Not as much as you want, there are limits. With a texas speed motor i wouldent go over 200 imo unless they have gotten their crap together recently and found out how to actually build a motor. Just because a motor is forged means nothing. Ring gap and bearing clearances play a big part and so does tune up on a 300 shot. Most plates wont support that and id suggest a dedicated fuel system as well. You also need to do lots of research on n2o tuning.

They didn't build it! And I'm not letting them tune it either! I have heard bad things about there tunes! I was thinking of taking it and having Nelson dyno tune? And I have a dedicated fuel system for the nitrous!

I don't believe you!!! J/k! Where's the pics of this beast? Sounds like you're setup is pretty nice.

pics or i call BS, you mean to tell me you paid to have a stroked and forged motor built, you have no idea how much you can spray, but yet bought a stand alone system for the nitrous, and you dont have a tuner yet for it.......you are either lying or you have more money than sense

That motor sounds like it could possible take a 300HP shot but there are a lot more factors in spraying that much nitrous. The main things that you need to watch out for in that big of a shot are ring gaps need to be set a little larger than they would be on a N/A engine. The other thing is to watch your dynamic compression because to high of dynamic compression can cause problems with that big of a shot.

Here is a good explanation of Static VS Dynamic compression.
