The car is running, and I took it for a spin tonight.
It's a different car for sure. The car has lots of low end, not like before. I got on it a few times and the supercharger whine is OMG!
It was worth all the hard work.
The car still needs to be dialed in and I need to fix a few thing.
I will post some pics later this weekend.
I am sitting now drinking a scotch and would smoke a cigar too, but I don't feel like sleeping in the garage tonight.
Now that I have verified that the supercharger work, and can now finally start into build which i should have started months ago.
The split second box is going in the trash!
Now its time for a custom tune. I am interested if you have the following on your car.
The challenge is that the ECU doesn't understand positive pressure, so ???
Options:
1) Todd at protomotive with larger injectors
2) AEM standalone
3) Other options are appreciated.
I also live in Crapafornia, so 91 is the best i get at the pump. I am starting to think that I am going to have to buy a 50 gallon drum of race fuel to mix.
You'll just need to get a tune that matches the fuel that available to you. Having to mix race fuel will get tiresome.
I'm using a Unichip right now with 993 Turbo Injectors and (1) 993 GT2 EVO fuel pump. It has worked flawlessly for me all these years.
I eventually want to get a Protomotive tune from Todd.
Go Protomotive tune - chip.
Mass flow network.
4.5bar FPR - if I remember correctly.
Turbo injectors cost too much - go for a cheaper alternative.
Meth injection.
Otherwise - Motec

Injectors and tune, all day long. Boxster/997 injectors (#0280158116) and a rolling road remap of the existing ECU gave me 405 of the smoothest galloping horses ever to grace the tarmac. Ditched the Uni-Q, ditched the extra injectors (blocked the holes), kept the original FPR, so simple, so clean.
Trevor is on the ball here. The Stock FPR is more then up to the task.
I recently put in a Bosch 044 (GT2 Evo) fuel pump because my stock one was making noises.

After doing a search, seems like you put a KN filter on the oil vent hose
For the carbon canister, Do i have to plug it? I read that if i don't hook to vacuum will get a rich condition and fail smog. Rich condition seems good.
Finally: The brake booter, do i have to install the check valve assy or can i just simply hook up the line directly to the vacuum line off the intake manifold.
Hey Windy,
What did you end up doing with the carbon canister connection? Mine is strangely connected to the TPC intake manifold beside the FPR and my boost gauge connection where it see's boost....
1) Where did you connect it to?
2) Did you reuse the check valve with the electrical connection?
Thanks for any help.
I'm wondering if this is the reason my Protomotive tune isn't meshing well with my current vehicle setup.

Do not connect that carbon canister to boost!!! The carbon canister connection needs to see vacuum (the input side of the supercharger where the ISV is connected to). You can also cap that carbon canister off if you want and it won't affect things much. This is how the carbon canister connection work.... when you are off throttle and your input side is under vacuum (bc the engine is sucking in air while coasting down), the engine will signal the electrical connector to open and that open the line to the carbon canister. This will allow the engine to suck in some of the air and fuel vapor from the gas tank and burn through the engine rather than just venting it to the atmosphere.

Thanks AXL!
Let's see if I'm getting this right...
Either:
1) Connect it to where the brake booster and climate control are on the low pressure side of the supercharger
2) Just leave it disconnected and vent it to atmosphere
3) Cap the hose off
Thanks again!
Believe it or not it's been running like this for over 8 years! But the Valve has been pointing the other way towards the engine... so maybe that has been my saving grace.
