Sure, the air is denser (per the huge cooling effect of the N20 expanding and there is plenty of Oxygen for combustion), just a non-mechanical method of getting more Oxygen in the chamber. Actually, N20 is good for an engine. Cleans the combustion chamber like you would not believe.

I think that N2O will love these headers with their much improved crossover setup. I'd argue that HP for HP N20 is better for your engine over the long haul if you are running the stock bottom end and if you don't use it at every stop light, just at the track and every once in a while.

I never said it magically ruins anything....but there is a greater chance for engine damage....!!! If the system or the user sprays at the wrong time.

The same thing can happen if you flash lean on a turbo setup, or if the Wastegate malfunctions and you over boost. Any FI setup is dangerous, all you can do is take as many precautions as possible to keep it safe.

that's why you have a window and a tps activated switch. I ran 20 bottles through my vette without so much as a hiccup.

So I was looking at the pics again and I realized that there isn't a flex coupler in the downpipe, just in the crossover. If the headers are delivered as they appear and you weld them up, you'll be rigdedly coupling the rear header bank to the rest of the exhaust system! Looks like I'll be buying a 3" flex coupler too!!! Unless something can done about that, it's a recipe for leaky headers.

Everything else is rubber banded in, so there is some flex...

I guess I'll wait and see what they look like... but the engine rocks quite a bit when you hammer on it.

Get a poly or msp motor mount or just rotate the stock one. It's a world of difference.

I must have bad timing, because I cant seem to ever catch him!!! I've left a couple messages for him, hopefully he'll call back today so we can get this price down a bit.

you are right, you will need the flex pipe or get ready for cracks.

How can you be surprised 16 people haven't paid? It's been over a month since the headers have been finished and still no exhaust clip.
