PettIt lists their S/C kit for 2004-2010. Do they support S2 now?
Someone posted this link in the S2 section.

BTW, I use 10.5 for leading and 11.5 for trailing
"For literally decades, Racing Beat has recommended NGK Spark Plugs for Street, High Performance, and Race rotary engine applications. The NGK R6725-11.5 spark plug is the Racing Beat-recommended Spark Plug for 12A and 13B Bridge/Peripheral Port Engines in either a Turbo or Non Turbo application. Price shown is for one (1) plug. This spark plug is used for both LEADING and TRAILING positions. This spark plug is NOT generally recommended for street use, unless you are running a highly boosted turbo-charged engine."

First quick log after break in oil change and plugs. 7k rpm and @ 7 psi boost. Trim at 18. Didn't have time to reset room fuse and drive for a while before logging. Will do on Saturday with more logging but keeping it under 8k rpm.

ok--i have a very small issue. I am getting some break up when the secondary opens under mod to heavy load .
I have noticed that I am running richer than I used too also? Before with the 7psi pulley I was running oem injectors and it was ok---np usual 14-13-12-11 a/f's.
Now with the 7psi pulley and upgraded to blues in the P2's I am running 14 (at idle and light cruise) straight to 11's with any real load ( always above 3K rpm). I have dropped to 10.5 a little higher up in the rpms. power is good.
Running an efi dude run tonight but that blinking cel makes me nervous!
Should I take the 2 blues out?

Actually he is referring to the Aux fuel injectors on the top fuel rail (outside left and right). The inner two injectors are the P2 top fuel rail S1 series 6 port engine.
The blue injectors are from the S1 series 4 port engines and do flow more fuel. When using the bigger pulley you must change the yellow Aux injector for the blue or your AFR will be lean.
I instead use the S2 series P1 for my P2 injectors and the S2 series P2 for my Aux injectors.

It took me over a month to find a second pair of Toyo Proxes R1R at a decent price $201 ea. The first pair I got for $128 ea back in early Jan. There is a national shortage of R1R because they are high quality tires for autox/road course and at a decent price. Well till now.
Toyo is holding to release more in March with a higher price and retailers are holding what they got so they can cash on already in inventory stock.
Anyway, heading to Homestead Saturday 5 March to watch the Rolex Grand Am and the RX8 for the first time.
