Upon receiving it, I was right. Everything is machined well to fit together properly and function properly. The ball seats nicely and the spring allows easy, smooth adjustment. I put it on my car and dialed in to boost pressure. Mainly, I wanted to reduce spool up time, and this device does help with that. Nothing crazy extreme, but noticeable.
Worked great for me at the road coarse track last weekend with no boost creep or negative affects.
I have hardly experimented with upping the boost, but it did work well when I went from 8psi to 12psi. I can't comment on holding that higher pressure at this point, but I am confident that it would work just fine. The adjustment nut is only about 2/3's tightened at this level, so I am sure the spring and ball will work as advertised. I have to get my fueling and other items right before I put more stress on the engine with higher boost.
The only negatives are outlined on a similar review:
1. inlet/outlet nipples are different tube sizes.
2. To adjust more than 1/16" a turn, the vacuum tube must be removed.
3. No mounting bosses to secure it. Using my tube lengths, I was able to find a way that keeps it in place fairly well
Overall, I would buy again and am happy to support 'the little guy' rather than the name-brand aftermarket tuner companies that offer cheap/sketchy products to the mass market that look nice but promote boost spikes and unsafe engine performance.
To lay it out simply, here are the pros and cons:
-Fine threading on the body allows for small adjustments (if you breathe on the adjustment screw of the NXS it will change by 2 psi, haha)
-Quality spring. The ball rattled around in the NXS controller at my adjustment level. I'm pretty sure it's not supposed to do that and I believe it's because the spring is overly stiff.
-Not made of plumbing parts
-Hits boost level pretty consistently (I did notice about a 2psi swing between freezing and warmer temperatures but that's inherent to all MBCs)
-Different sized nipples on each end. This is not a huge deal with some high quality silicone tubing, but it is somewhat annoying. I ended up using Upgr8 4mm silicone vacuum tubing. It fits both ends pretty good, with the large barbed end not requiring a clamp. No way I'd trust the smaller end without a clamp.
-Adjustments can be a bit annoying because you are supposed to remove the tubing as the adjustment threads are part of the body itself. Not a huge deal either, I just spun the large barbed end inside the tubing rather than removing it as the instructions suggest.
-Not really a great way to mount it. Since the adjuster is part of the body, there's no mounting holes or anything. I just zip-tied it to something, but it's not ideal in my book
Sure you may be able to round up all the basic pieces, but the Dawes device puts them all together, plus a few tricks you probably didn't even know about.
Do yourself a favor and pick one up. You will not be sorry!
Happy boosting and save a mini mopar!
The ball is very light and bigger than competitors, seats well. Fine adjustments.
I used this switch with it: [...]
I'm impressed, simple and easy. Works good. How the car should have come from the factory :)
