anyone log IATs? pulley size?

I mentioned this earlier. Contact Innovate - they will send you replacement clamps. I cut the old ones off (slide the new ones on first so you can tighten it fast and not lose a lot of coolant).

Anyone else see this on Innovate/Abby Motorsports FB page? Haven't heard much about IAT readings in a while, just figured i'd share it.

Abbey IAT(air intake temperature)upgrade on the Abbey Motorsport Sprintex Supercharger kit for the GT86/BRZ.

we move the stock air intake temperature sensor from the Mass air flow sensor on a stock car to after the Sprintex Supercharger to read charged air temperature for better calibration with the EcuTek International Ltd software.

Thought I had this sorted out but it doesn't appear so. AFR's still getting leaner towards the top of the rev range. It seems to be worse in higher gears.

I tried locating any vacuum leaks by spraying starter fluid everywhere I could think of on the intake pipes/couplings/throttle body/elbow fittings. Where do you guys most commonly see these leaks? Could it possibly be anything else?

[choi0706]

you should probably look at the port injectors.. seen those leak if you weren't careful with the gasket on bottom..

or it could just be the tune...send him some data logs.

I am pretty sure IAT's in the manifold do not read correctly. The sensor doesn't stick far enough down into the air flow. The manifold gets heat soaked and the IAT reads some of that heat.. Long story short we need a better solution. I saw a log somewhere of a WOT run with a post charger IAT.. I think the temps continued to decrease for the first 5 seconds into the run... then kept increasing after the run was over.. temps should fluctuate with boost.. not lag behind it.. reason to believe it was reading the temp of the manifold more than the air..

I thought I read something like this, but couldn't recall. Good post.

My scientific solution was touching the lines after 6 WOT pulls to gather data logs. The line going to the front mount felt about 150 degrees (water temp) and the return line going into the supercharger felt a few degrees over ambient of 60 degrees. It's enough for me to know it's doing it's job, just wondering how effective it cools the charge.

you should have touched the top of the supercharger instead

no joke. non-ic, it would stay hot for like an hour or more after the car was off, and be SCORCHING hot when I touched it. Now I can throw my hand on it. When its real cold out (like today), it feels like a hand warmer, lol.

Here a question/thoughts for those of you that jumped from the 75mm pulley to the 70mm pulley.
If I make the jump to the 70mm, sounds like I will need:
-Stronger clutch installed (like act streetlight flywheel and street clutch)
-Intercooler
-70mm pully
-I may also do a meth injection
-I don't want to bother with e85 yet
This means I'll be spending around $2.5k without meth (parts and labor [intercooler 1200, clutch/flywheel $566, clutch install $600, retune $200]) and over $3.5k with meth.

With all that, is the supercharger or engine expected to have a shorter lifespan? I don't want to have the car fail on me in a few years because I overstressed the charger or engine. I want this car to last. I do a few track days a year. I have most all of the less expensive supporting mods like oil cooler as you'll see in my build thread.

Would I need to change the supercharger oil more frequently that recommended by innovate?

Depending on my tax return I may get some or all of this stuff. My guess without looking at taxes is probably I'll only be able to get the intercooler.

Not necessarily. I went to the 70mm pulley and didn't change anything. It depends on the gas you can run. Do you have 93 or 91? I have 93 so it may be different, i've heard 91 with the smaller pulley and no intercooler isn't the way to go (can't remember who said it).

I don't have a clutch either. I plan on going to get tuned on e85/flex fuel with the stock clutch, hopefully it holds. I DO plan on upgrading however. But if I was to stay on 93, I wouldn't be touching the clutch. It holds just fine.

As far as frequency of changing the oil, I don't see why that would effect anything. I mean the service is suppose to be every 30k, and I checked mine with like 10k on it and it was so low it didn't even hit the dipstick. So that should be something checked frequently anyways, regardless of the setup.

I do recommend the intercooler though, either way and no matter what gas you are going to run. Just makes for a way more efficient setup. Consistent power as well.

Can't comment on meth injection, no plans to be running that.

I buy Costco 92 octane gas as it's next door to my house and cheap, yet good gas. Someone told me at the mechanic shop that running a 70mm pulley without any of the other stuff like intercooler wouldn't work very well. I can't remember exactly what he said as to why.

I need to remind myself to check the charger's oil level since I haven't done that yet.

man, 92...now your throwing me for a loop

maybe bill @DeliciousTuning could come answer this, since he has experience with 91 gas and a lot of different setups.

Don't want to throw guesses out there on ya.

What's the process for changing the oil on the charger? I know where the fill plug is, where's the drain?
