@ntaphse That is definitely one way to do it... But I remember while back someone pointing out a bolt that is in the back of the manifold that can be taken out and replaced with a nipple. This would be the easiest solution.

Yeah I saw that too, after I drilled my MAP plate. Let us know if you figure it out.

Apparently I have a vacuum leak somewhere between the MAF and blower on my system. After 5k RPMs at WOT i've noticed my AFR heading towards the lean side on my wideband. The odd thing is that if i apply ~75% throttle AFRs seem to behave as expected.

Both @moto-mike and @DeliciousTuning have reviewed the logs and suggested that there is a leak somewhere between the MAF and supercharger. @moto-mike said he had to basically increase fueling about 30% to compensate (he can probably provide a little more clarification)

Myself and @civicdrivr have looked everywhere we can think of:

• Pulled the plastic intake tube from innovate, tested to make sure there were no cracks or holes in that and that it held pressure.
• Also pulled the stock intake box and K&N filter to ensure that was snapped together properly.
• Pulled the supercharger off the manifold to verify the o-ring strips on top of the blower were still in place, they were.
• Checked all of the supercharger to intake manifold hex bolts
• Cleaned the MAF sensor
• Removed the catch can going to the intake breather and went back to stock routing
• Removed the injectors, applied dielectric grease to the o-rings to make sure everything sealed up properly and reinstalled.
• Sprayed starter fluid over any area i could see as being a potential source for leak with the car running, no change in idle noted.

I'm going to try and pull the other catch can today and return that to stock routing, but other than that I'm at a loss. Do any of you guys have any suggestions on where to look, or tips/tricks that I can use to help locate the source of this leak?

Is the o-ring on the MAF good? They can tear when re-installed.

Will that work with a SC setup? Or only turbo?

looked like it. I'll double check at lunch. would it hurt to throw a little dielectric grease on that o-ring as well?

Yeah.. if there is a leak somewhere you will find it. I have even seen some people put some sort of smoke bomb in while they do it so you can see where it is coming from. I don't know if I believe the whole 1psi per second thing.. put it directly on the throttle body. I wouldn't put pressure in the plastic tube. If ANY of the seals are bad post throttle body you will know.. I would try it with the vacuum hoses off and plugged to isolate the problem to the charger or some other system that uses vacuum. (brake booster, pcv, ect.)

smoke machine at the brake booster and rubber glove on the intake pipe.. if you were local I would lend you mine..


check near the injectors..

I wouldn't. Anything that can potentially get on the maf is risky. If the o-ring isn't torn you can trust it.

Thanks, ordered one.

Can you go into more detail on the smoke machine and how you connect it? if it's something i can grab or put together locally i'm willing to give that a shot. Where near the injectors? port side?

Gotcha, thanks.

thats the one i have.. saved me tons of time and headaches searching for lean codes..

homemade,

you basically seal the intake and fill it with smoke, shine a bright light to expose where it comes from..

it works great finding exhaust leaks too..

port injectors, those seals are one time use, yet innovate says to reuse them.. seen it on other supercharger applications, they leak from there..

Probably after this weekend. Just doing some final tweaks. Looks to be version 8.4 coming soon.

I don't agree with this. You are suppose to lube up the o-ring..or you will tear it with it being dry.

@xjohnx - did you upgrade your map sensor or still stock? The Omni map sensors o rings are slightly bigger and a TIGHT fit. I actually tore mine the first time around.

I used dielectric grease. Get the o-ring lubricated, but don't put 2 gallons of it on there.

Edit: Did you check the three lines coming off the back of the supercharger? follow those to the other side and make sure the other side of the hoses aren't leaking as well. Theres only so many spots with this thing that could have a vacuum leak.

Might have just fixed the issue. Reflashing now and will update momentarily.

BTW Little side note: I have been chatting with an Innovate Rep and was given a suggestion to help out with heat. This may be very beneficial to those who don't want to upgrade to the IC kit, or have the blower off the car and not installed yet. If I ever pull the charger off I may take a look at doing this. Now that my intercooler kit is attached though, I don't want to deal with filling that coolant system again

After running it hard, the blower is still just warm to the touch. 13500 is the p/n from Thermotec. For the BRZ, I’d put some on the very bottom face of the manifold and the runners. The next effective place would be the bottom facing of the nosedrive casting and the inlet casting.
