It takes 7 hours only for supercharger install.

if you install v2 kit, there is a bolt below the supercharger bracket.


"Apply thread-locking fluid to the Cap Bolt to install
the Supercharger Bracket. Loop the V-ribbed
belt around the pulley of GT Supercharger.
Install the Supercharger bracket and V-ribbed
belt.
NOTE
 When installing the Bolt M6 L18, use a ball
point type or short tip type hexagon wrench
for easier installation. "


in my case, it tooks over 30minutes for that ONE bolt.

I would suggest to separate parts according to the instruction steps prior to start. Also cut the hoses prior to start (just ensure you measure 3times before committing to cuts). This is a precision kit. With preparation I.e. making the suggested cuts it will bolt up like a factory part. My 2 cents. I'm out.

I have two other people helping me and I have no idea how you managed to get some of these things completed alone. The bolts in the bumper support just blows my mind that that is the solution. That was ridiculous. Lol.

Installation does not require removing the timing cover or either timing chain therefore mechanical (cam/crank) timing should not be altered. No timing light needed. Ignition timing is/will still be controlled by the ECU and will definitely require a tune for any supercharger.

Thank you for the support. Just like to be as ready as possible.

I used the canned tunes from the supplied HKS interface, however, I noticed it was not preloaded until we connected it to a PC and it does NOT have the 93 octane option. Why is this missing?

[Scott@HKSUSA]

We chose not to supply the 93 oct calibration "as delivered" because not everyone has access to 93. But everyone does have access to 91. To help everyone understand-

The Flash Editor memory has 4 calibration "slots":
Slot 1: stock calibration (permanent - can not move or change within F.E.)
Slot 2: 91 oct calibration (writable - Pro-Dealers can move/change/edit)
Slot 3: E85 calibration (writable - Pro-Dealers can move/change/edit)
Slot 4: Power Writer [open/blank slot] (writable ONLY after F.E. has been married to a ECU)

Since we can't change Slot #1 and we can't pre-load anything onto Slot #4, it left with us with 2 pre-loadable slots for the supercharged calibrations. 91 and E85 are the only two calibrations that cover all the bases, so that's what we ran with.

[HuntingtonFRS] Now that you're up & running on the 91 octane calibration, if you'd like to send your F.E. to me, I can upload the 93 oct. cal. into "Slot 4" for you.

For The US market, our supercharges, if purchased from an authorized dealer have a 1 year warranty which is great news. HKS customer service has been decent to me so far. a bit rough at first though. next step is to send the compressor back and get a diagnoses from japan. I am waiting on evasive to provide a receipt for my purchase to complete my return criteria for HKS. engine teardown will finally be completed today. still in discussion for what internals to use.

Thank you for the detailed response! Nice to see great customer service.

If I get the 93 tune and end up with a tank of 91 octane I assume it's fine and I would just have a loss in HP? And if I have a 91 tune and run 93 no harm?

Do not run 91 with a 93 tune...

The reverse is of course totally fine.

[Scott@HKSUSA]

Running 91 oct. on the 93 cal. wouldn't be good. If you're in a pinch, sure the engine would run on it. But if you drove it aggressively it would certainly knock.

Thank you and sw20kosh. My only concern would be if I'm on the 93 tune and take the car out of town and find only 91 is available.

[CxG]

Well you should be able to have the 91, E85, and 93 calibrations avail after could you just run a different map if you end up in a area with 91 only. Or run to a near by auto parts store and buy octane Booster?

Just stay away from those 91 octane states. They're no fun anyway

You're not going to lose your 91 oct tune so you can always flash back & forth (91/93) if you needed to.

[Kodename47]

Running 91 on a 93 tune is fine all the time you're not going WOT all the time. I can't imagine there's much difference in closed loop areas of the tune so if you can only find 91, it'll be fine to drive around on until you can get good fuel.

I installed HKS V2 kit with 40.5mm air restrictor.

and yesterday, I changed 40.5mm to 41.5mm ( and also make different tune for new restrictor )

DI injection time @7214 was 5.74ms (stock D/P ratio)
and MAX MAF Volt@ 7288 was 4.76v

I think there is more - but small - room for more boost. (42mm will be ok)

I like 41.5mm much better, I feel more torque over 6500
with 40.5mm, there was hesitation over 6500.
