Put some rags in the tail pipe.

Block it with something other then your hand. and listen for the hissing noise.

those pictures are pure pornography...


hasnt it been established that backpressure is always a bad thing, velocity is what you want in the pipes?

I haven't been around here for a while ... but...

Less Backpressure = quicker spool. Period. No exceptions, no excuses. It doesn't matter if it's a Miata turbo or a Big Cam Cummins. Turbo's hate backpressure... Leaks behind the turbo make no difference. Leaks ahead of the turbo are very, very detrimental. Also be sure you don't have vacuum / boost leaks.

some of you have failed to consider the cyclonic effect of the often overlooked sphister valve.

cyclone - you put that intake I let you borrow in yet? I'd hate for your car to suck in a rock.

Yep. Turbos don't like foreign objects. ask me how I know...

Fastrax203

Haha yeah we met up and he popped the hood. I was like...waaaaiiit a minute...where's the filter?? Luckily I had my OE box just sitting in the garage so I let him borrow it for the time being.

Aww I love Rocks Yes sir I did, I might just buy a filter and stick it there or get creative lol.

I'm also thinking about sneaking over to your house while your asleep and copying your lip

If you need a filter for your adapter I've got plenty. Just let me know and we'll swap it out. I'm gonna be getting bodywork done pretty soon so PM me.

There's no arguing about the principles of fluid dynamics, ,ie, if the pressure downstream of the turbo decreases, the energy in the exhaust stream increases. More energy in the exhaust stream = quicker spool = more hp

You can reinvent the wheel if you want, but you can't violate the laws of physics.
