Most folks replace theirs because of suggestion like above (opinions, which are based on what?) or suggestions from shops/tuners (there's the ones making money off of you).

I should have said stated you would eventually*. The fuel injectors and fuel pump were in the duty cycle of 90% plus at WOT. In the best interest of not having a fuel pump/fuel injector fail you it would be a good idea. But yea, I should have made that more clear and stated you would eventually need it.

Thanks pgrandberg11

I had no idea Kraftwerks provided a BOV for this kit. Does anyone on here run it? would you recommend it?

If you are talking about the one that is provided with the kit, yes you would need to run it. It dissolves boost pressure when you are street driving and not on WOT. The bypass valve will shut close when at WOT to allow the psi to climb. If you didn't have this installed, you would have a huge hole in your hot side intercooler piping and you would never be able to build boost as all the pressure would shoot out the hole from the rubber molded hose. You can run this recirc or vent to atmosphere.

I was referring to the one that was shown on 86speeds website. I saw the Kraftwerks one and a Turbosmart one. I just assumed they were upgrades or different sounding BOVs.

oh ok, yea I just took a look at this one:

http://www.86speed.com/performance/k...blowoff-valve/


http://www.86speed.com/new-products/...blowoff-valve/ (this one comes with the kit)

I don't think I'd recommend the large BOV since it states that it should be used in applications with 18+ psi. If you're not running enough boost, you'll never be able to completely close the valve. I'd just stick the standard one. The standard one is actually pretty loud in my opinion especially if you let off after hitting redline...

ahhhh ok. I was under the impression that the "standerd one" you linked didn't already come with the kit. Im waiting for my setup to come in the mail this week which is why I wasn't sure. You tha man for answering so many questions here!

I just wanted to give a shout out and huge thanks to CJ @KraftWerks

As I was looking to purchase a car with an SC in it, he was extremely helpful answering all of my questions, and went above and beyond in helping us sort a few things out in an unbelievably tight timeline. I don't expect companies to provide this level of customer service anymore. Well done!

I'm really hoping they release a DIY video regarding belt tension, seems like it would alleviate a lot of the stress around this system.

It really doesn't get any simpler than this explanation from pgranberg11.

"Use the half belt twist method. There's a little cutout on the bottom of your supercharger plate that you can't fit your thumb through. Try grabbing the SC belt and twist it half way. With your right hand, put your thumb on first and put your pointer finger on the back of the belt push up on your thumb and pull down with your pointer finger until the belt twists half way."

The stress regarding this system will be there for a while until more owners testify to having no problems than when the system first came out. I was hesitant to purchase this system, too, but the price and how "clean"/ OEM the setup looks won me over. We'll see how reliable this kit is in the long run. I did purchase a spare belt just in case. The other SC I considered for this was the Cosworth kit, but I didn't want to spend that kind of money since I have my car getting a V8 swap. Two car projects running simultaneously puts a hurting on the budget.

Just bought this kit!! Coming in by the end of this week and installing next Monday. So excited! Any tips on installing the oil reservoir?

I would definitely back that statement. HIGHLY recommend buying extra belts. It's a supercharger and belts will break. Yea it's nice that you can still drive without a belt on the sc (I've done that from Gingerman raceway in Michigan all the way back to chicago on the same tune and was fine, probably don't recommend doing that however..) here's the link that I use to get a belt, it's typically the cheapest:

In regards to stress, I believe people tend to make it a lot more worse than it really easy. Honestly, the biggest pain in the ass with this kit was figuring out the belt and the oil cooler setup up (if you plan on tracking, not necessary if you don't). But once you figure out the belt, the kit is nice to drive.

It would help if you have two people. have one person in the car and prime the sc while someone else pays attention to the oil level in the reservoir. don't let the reservoir ever go empty, but don't overfill it either. I don't know how you would do it with one person otherwise.

good luck and enjoy the boost!

Sounds good. Going to install at my shop with the mechanic I work with. But for the placement of the reservoir where did people install them? Ive seen people with it in the front in the middle by the bumper. Any reason why it would benefit from being located there instead of being by the battery?
