I sold my 4" already... but I do happen to have a 3.8" sos pulley if your interested.

 

Um....yeah! I'm totally interested. Might be a bit over 7 psi but I'm hoping I have enough extra duty cycle to handle it.

 

Yeah you will likely see 8psi. Will be a nice bump for you. PM me and we can work it out.

You have some timing you can play with... so retarding it will surely aid you if it turns out your lacking a little fuel. Should reduce your afr some and give you a bit of a buffer with any possible detonation tendency. Though I will tell you from experience, unless your car is running really high AIT from racing around, you wont ever detonate with this pulley if your running 12.5afr or richer... due to the nature of the SC linear boost with factory timing map. At 10psi I started getting some audible detonation pre vtec so I went back to 9 psi. If my methanol would inject quick enough I could run several pounds more boost, but it wont... so I'm playing it safe. Still cant complain about my output for what I'm using to mange things. Its kind of fun to feel like your cheating lol

Anyway enough chit chat, at 8psi you will be in the 325whp/215trq range which will be a nice bump. You are lucky if your making 280whp now.

 

Giles' company was Holyroller Dyno, which has closed its doors. Twiztid (Scott) runs Ballistic and is very much still in business.

 

Guys, would 550cc injectors with bolt on's (Exhaust, header, HFC) be sufficient for a 11psi setup?

Also does the 'SOS' map sensor work with the greddy emanage ultimate?

Cheers

 

I'd go with 650's to be safe if you stay at stock fuel pressure. Using an FPR you could get away with it.

 

You can use any MAP sensor you want as long as you base the y axis of your map off voltage and not PSI. Figure out the equation for translating the voltage from that sensor to PSI and you're set. I'm about to do this with a 3-Bar I got from PLX.

Edit: But you won't be able to ditch your factory sensor because the ECU will still want that signal to stay happy in closed loop.

 

I thought they was a limit the greddy could control? or is it 650cc?

 

There was a limit with the Blue unit, but not the EMU, as far as I know. I'm planning on controlling ID720's with mine.

 

Interesting thanks

Going to download software to have a look at the feature and familiarise myself.
