Default Is it normal for a Miata engine to be this loud?

So I'm about to slap on my turbo and I've done all the pre-flight checks, and everything seems fine. The one thing, however, that has always bugged me is how much noise my engine makes, since I don't have another Miata to compare it to I'm not sure if it's normal.

I go up to about 4,000rpms in the video:

Are you guys sure? I'm running a 100 shot of NOS, I'll be lucky if I didn't blow the welds on the intake manifold.

Well then in that case just stop granny shifting and not double-clutching. Then you will be fine.

I don't know, the floor pans may fail at anything above 75 NOS.

You're ******* joking right? The intake is solid up to a 150hp++ shot but the problem is the front differential usually breaks synchros around a 50shot with that type of antilag.

This thread is now about how pathetic our lives are since we can quote Fast and the Furious from memory.

Koni adjustables, they'll save us 2 pounds, and give us better traction off the line. Here's your basic design, and here's what it could look like when it's finished.
