S/C kit tuned on E85
I meant to post this a while back, but I got my AP2v1 an E85 tune after performing some upgrades to my S/C setup. My old S/C setup, which I ran for over 3 years, can be found below.
https://www.s2ki.com/s2000/topic/693...acktrax-tuned/
For my recent dyno, my gains are ~263whp/165ft-lbs over my stock baseline on the same dyno. These numbers are at ~16psi and only 7800rpms because of belt slippage. There are future plans to help prevent the belt slippage, but for now I am happy with the current results. I should be at atleast 18psi and +30whp when this belt slippage issue is addressed.
I also have a Jeff Evans etune for 91 octane (limited to 10psi). I plan to use this tune to run a tank of 91 octane every few months or if I need to use the S2K for commuting.
Parts carried over from the old setup
Stock exhaust!!!
Stock exhaust manifold
Stock fuel hard lines
Stock internals
Berks test pipe
AEM EMS 1052U
Dual diverter valves (Forge Splitter and TurboSmart Kompact)
List of upgrades
Novi 1200 oil-fed (upgraded from a Novi 1220SL)
3" SOS pulley (from a 3.8”).
ID2000s (upgraded from RC 650s)
FBM hanger (dual FB340 pumps) with stock feed kit. Second pump activated at X psi.
Fuel Lab 6 micron fuel filter
InlinePro fuel rail (wanted extra port to drain gas tank)
AEM FPR (stock fuel pressure)
Peterson Breather can (upgraded from sealed catch cans and krank vents)
UPDATE - 10/14/2012:
So my belt slippage issue was resolved after replacing the SOS S/C pulley and Dayco belt with a Reichard Racing UltraGrip S/C pulley and Gatorback belt. Car now sees ~19psi at peak rpms. After some tune touch-ups, car put down 492 whp and 319 torque on a Dynojet. This was the first S2K on their dyno and I have no baseline, but supposedly a stock 370Z puts down 280whp on their dyno. AFRs at WOT are .74 lambda/10.9:1. I wanted the AFRs leaner and rpms rev'd a little higher, but my tuner did not feel comfortable tuning my S2K anymore than were it was at. My S2K is primarily used for the twisties so I can live with the current power.

Idle with my 91 octane etune is kind of rough. I guess you can call it an oscillating idle. The etune is from Jeff Evans and is still in progress. Idle is not so bad with my E85 tune, but there is still some oscillation. It makes the car sound mean for a 4 banger, LOL. It's all good once the car gets moving.

that is fantastic for a stock exhaust/manifold car. congrats. how small a pulley you running? go up on the crank pulley if possible. this will allow for larger sc pullies but still hit your desired boost. 3" is known to have issues

Thanks. I am running a 3" SOS pulley, but have a replacement pulley (Reichard Racing UltraGrip)coming soon. With the 3", the blower will already be over spinning with the 5.45" crank pulley at ~8100 to 8200rpms (forgot the calculated rpms). I did consider getting a 7" crank pulley from ASP when looking into getting a 1500 blower, but I decided to go with the 1200 instead.

Is this quiz time? LOL. At what engine rpm? Assuming it's 8400 rpm, then the blower should be spinning at ~47,171 rpm.
Calculations used...
(crank pulley diameter/blower pulley diameter) x engine rpm x 1200 blower internal step ratio = (7.0"/4.5") x 8400 rpm x 3.61 = 47,171 rpms
