How much it can take before it blows?

I have seen a GTO with a Black Mamba spraying 250 so I would say at least 250 is safe

It won't blow... Its more so about distribution to the cylinders based on if you are running it through the front of the intake or not

FreakChevy

What do u mean? I saw it blow after 350-400 shot or is it bad tuning?

You can backfire it on a 50 shot and break the intake... Thats not saying much.

250-300 is the most anyone should be spraying through the intake. Personaly anything more then 250 and I will be installing a direct port set up.

Have you ever tried?

FreakChevy

So it can handle 350-400 shot if it didn't backfire?

I wouldn't be afraid if you were using a direct port

If you have that intake on your motor odds are you dont have what it takes to acctually use 350-400 worth of N20.

Head flow, cam shaft, exhaust.

Just sayin.

We tried 200, and 250 through a plate on a 102. The plugs read very uneven. Went back to a 92, and the plugs even out. This was on a 427 tuning 7k.

That is not a intake problem that's a plate problem. I would not go over a 150 shot on a plate or nozzle. It's like trying to get 1000whp out of a remote turbo kit instead of custom manifold setup under the hood. Sure you could do it but it won't be as good or reliable. If your serious about spraying DP kits are worth every penny for peace of mind.

I personaly havn't tried but plenty of people around here have pushed the limits. One has already chimed in this thread. My motor is built for a 350 shot. This year will be the first year out with it and I don't plan to go over 150 on my nozzle. For next year(2013) I hope to have a DP set up and jump to 200-250.

You are comparing two compleatly differant things. The turbo set up is just trying to push a ton of boost way to far(length) to be sensable. With nitrous you are relying on air flow to take just the right amount of nitrous and fuel to each plug.

Go **** in the wind and see if it looks like it does in the bathroom. Then try to blow air down a short and long tube. That is the comparison you are making but my demonstration will illistrate much better what we are trying to accomplish.

Just an FYI, Paul Major ran a rear mount turbo and holds the fastest LS time for anything LS.

There are a ton of guys spraying well over 150 shots on plate systems and it has been proven over and over and time again that a ls style intake doesn't distribute well especially on nitrous. Just ask Carter01 and camscam.

Well said.
To many people do not realize that at these power levels the total combination is very important.To many people think just because they have a forged bottom end its as easy as throwing the pill in.

Roger,
The results you and Mike seen between the two different intakes using the same plate technology is a prime example of how intake flow delivery can vary from engine combo to engine combo. On that engine the fast 92 did a better job with the nitrous delivery. Reading plugs is the only way you would have ever known.

This is why I preach that reading the plugs on these higher hp levels is very important. The wirdeband will show an over all airfuel. It would never tell you that you have a cylinder burning hotter than the average reading.

so if you do only have one cylinder burning hotter what do you do? just up the fuel jet a little?

Plenty of copanys including Nitrous outlt have upgraded plates for EFI systems but any base plate kit is not going to be able to distribute evenly to all cylinders past a certain point. I have had talks with Nitous outlet HSW and others about this for years trust me the plate is more a factor than the intake in this situation. Not to say a poorly designed intake won' affect that but the FAST 102 is far from poorly designed. As to the remote turbo setup one guy going fast doing soething doesn't make it right. How any real race cars do you see out there running the turbo half way back of the vehicle? It is a bandaid for a custom manifold or lack of space under the hood period. Lag is increased weight is increased due to pipe length its just not the right way to do it.
