Is that a -91 or -92 blower? How many lbs of boost?

c38-91 and 14psi on pump gas (93 octane)

edit: btw, I saw the vid of your car being put together by LHT and it was the motivation behind me relocating the air filter to the same location as yours, props on how your car came out

My plan is to go boosted come springtime, I'm glad I ordered the SOS wiring kit just for peace of mind. I've seen enough from all tuners that the grams pump is junk, but now that I'm hearing about the injectors being shit too I might get myself some ID 1050s and call it a day....I thought Grams were just rebranded bosch injectors? I wish KW would just offer the kit without the fueling, save me a few hundred bucks.

well according to Evans he’s seen 3 out of about 100 grams injectors with issues... he did recommend the id1050 if I swapped them out but he was pretty confident after the tune that my injectors were working fine...

we we were both pretty happy with how things turned out... with the exception of the fuel pump & the vtec solenoid bolts it was a 100% out of the box bolt on kit

I was troubleshooting a problem with my kit and I noticed one of the mounting bolts backed off from the supercharger. I took the bolt off and realized the bolt went straight through the supercharger! I'm not mechanical engineer but this doesn't seem right. Is anyone else's supercharger like this? I checked and all four mounting bolts went clean through into the supercharger.

the photo shows the hole with a light going through the supercharger.

Hi!

I would like to know what is the difference between an Ap1 kit and a 04-05 Ap2?

I bought a kit that comes from an Ap1 with the 30 mm upgrade and the pulley is a 90mm.

Did everything fit on my Ap2 without problems?

I wrote to Kraftwerks but I got no answer ....

Thank you!

I just posted on another thread. I received my kit last week from KW (2006 S2000 with -81) It comes with black oxide ARP bolts now for the Vtec solenoid mounting and there is a 3rd mounting bracket in the package. if someone can help me post pictures I can text or email them. Does anyone know what the 3rd mounting bracket is for? It is "L" shaped with one open hole and one threaded hole.

Also, what are the torque specs for the QTY6 bolts that attached the KW crank pulley to the adapter? Red or blue thread locker for those 6?
