That looks like a great DIY.

Great job on the DIY!

One of those pictures looks oddly familiar, almost as if it were my car... :)

Awesome guide!

Hello,

That is really nice. I appreciate you guys getting that together and posted up. I have a video all done also. I will be getting it up and running hear soon also.

Thanks T.C.

Great DIY! A couple things though.... shouldn't the FPR and actuator be connected to the plenum ports and NOT to the manifold ports?

Also, I have a Hondata gasket so a few things didn't fit quite right. For the blower bracket, I actually notched the holes a little more and mounted it upside down to get that little bit extra that's needed.

oh, and the assassin plenum ports are 1/4" too, not 3/8"...
(1/4" npt 90 x 3/8" hose barb = brake booster)
(1/4" npt 90 x 1/8" hose barb = to fpr)
(1/8" x 1/8" x 1/4" hose barb tee = to plenum 1/8", fpr 1/8", 1/4" to boost actuator)
thank you drive through

^^^ Again, different setups will require different tweaks - like the boost and vacuum line routing preferences I guess - this is based on TC's recommendation for Stage 0 Sniper. I'm guessing you'll be fine running the FPR and actuator to the plenum also (like most Assassin setups I've seen), and that perhaps TC recommends this way for STG 0 to squeeze a little more performance out? Not exactly sure why, but this is what he recommended for MY setup (and it's running GREAT!) - he might recommend something different for your's... :thumbsup1:

12sec - thanks much for posting, and thanks again to everyone I borrowed from... :rolleyes:

Very nice write up man.. Thanks for taking the time to do that.

1+

Thanx man this should be helpfull. Im sure alot of ppl are gonna be happy they have this in hand lol:thumbsup1:

Not a problem.

That is freakin sweet!

Hey TC - Do you think we can get the video burned on a DVD with our kits? I do not have any time to install mine and I have a very capable shop doing it, but I am sure this would make their life a lot easier. I would also hope it keeps my down time to a minmum.

The FPR and Boost Actuator need to go to the manifold. On the manifold they will see pressure and vacuum. On the plenum, they will only see vacuum.

Thanks T.C.

Wouldn't you WANT them to only see vacuum? By putting them on the boost side, you'll have pressure against the diaphragms, right?

I assume the bypass valve is fully open under full vacuum and closes more and more with less vacuum, eventually becoming fully closed. It would have to be closed fully at atmosphere in order for the blower to start making boost. At this point there would be pressure against the diaphragm, trying to move the valve past its closing point. So basically, the actuator would operate the same way whether you put the line to the manifold or the plenum, but there would be unneeded reverse pressure if you put it on the manifold side.

I understand the FPR.... sort of. The less vacuum/more boost you see, the more pressure your FPR would create.... meaning more fuel (rising rate). I have an AEM FPR and 290s with the vacuum line to the plenum. I did a preliminary street tune to a 13.2 all the way across and it tuned very easily. The adjustments to the mafterburner are only a few points different from beginning to end, and my FPR still increases pressure slightly with more revs. I have no need for increased pressure at this point, so I see that it wouldn't affect me now. Should I move that to the manifold and retune?

bump for learnin' me.

^^ Hey Nul - just give him a call - I'm betting that he can talk much faster than he types... :drive:

Yeah, I don't like calling him... it takes so long for him to type because he's a hunt-and-pecker... but on the phone he's just a pecker. lol j/k I'll give him a call after he comes back from vacation.

I talked to him on the phone and he confirmed this. Not the way I had mine but I guess when it goes back together in two weeks I'll do it this way.

which way is what? lol

He said this is the correct way.

"The FPR and Boost Actuator need to go to the manifold. On the manifold they will see pressure and vacuum. On the plenum, they will only see vacuum."

That is not the way I had mine but I'm gonna do it this way when it goes back together.

I dunno... like i said in the previous post, I can kinda understand the FPR being on that side... but the actuator doesn't make sense to me at all. U sure he wasn't drunk, pillowfighting, or watching little house on the prairie on mute, completely naked while sitting in a leather chair, tweaking his nipples with a pair of pliers, with a micheal jackson record playing? (he always gets a little spacey when he does that)

lmao I'm not 100% sure what he was doing but thats what he said. I'm kinda with you on this. I'll ask him again, I'm sure I'll talk to him tonight.. He was kinda outta breath night before last when I talked to him.. lol

Haha! He's bustin' ass trying to get some stuff done before he leaves for his 20th vacation of the year. :doh:

lol so is it right? haha i still need to know .. because the sniper goes in this weekend for sure... FINALLY got a nice day this week to install

it's right 4 sure.

The FPR and boost actuator go to boost.

it did not show pics or info, need help with alpine setup thanks.

who is TC?
