Very good. I have no complaints. My afr is at 14 to 15 under cruise then 11.5 under WOT. Car drives great. It does not behave like stock under cold idle, a little high and jumps around a little whn idleing down. Not a big deal. Going to ask about it when I retune with my 3in pulley. Hoping for 400

 

Nice...you should have them run it up to 8500 rpm. Please upload a scan of your dyno run after your touch up. Did you get a baseline dyno?

 

uhm....No.
do some more reading. 700+ is extreme on stock block, yet works fine.

And hell yeah, def keep us posted. Been wanting to see more numbers from that blower on 12-14 psi.

 

No baseline unfortunately. Its on a dynapack, suppose to be middle of the road on reading compared to the rest in town. Does anyone know If the paxton 1220 is good for more than 12psi? The smallest pulley SOS sells is a 3in. That's 12 psi @ year the blower and 11 or so @ the manifold from what I've found. Would it be okay to try a 2.75 or would that put the blower out of efficiency?

I'd like 12 to 13 @ the manifold. Would be good for 425 or better. Just don't know the capabilities of the blower

Fuel is still @ 65psi, plenty to go on the injectors, and am using a boost a pump to ramp up fuel volume on a walbro pump.

Looking forward to hearing from someone on this

 

Well it made 12psi, 8200 rpm, and 415hp, 277tq @ 78 degrees. The dyno I went to was a dynocom, and reads on the low side by what people say.

Awesome numbers Id say. Im maxing the charger out with my 3in pulley and will need to go to a 1200 Paxton for more.

Good for now

 

Holy smokes...very nice sir! You should create a new thread with a snapshot of your dyno sheet and details of your setup. Any idea what a stock s2000 makes on that dyno?

 

Usually 200 to 210 on a stock car. So successfully doubled the stock output. I can see how this is addictive. I already want more!

 

That torque is incredible, awesome numbers! Please post dyno sheet.

 

If you don't mind what are your suporting mods?

I have the SOS stg 2 kit with 9 psi kpro tuned ap2

I've been intrested in raising the boost trying to get more power also was that map sensor pnp with kpro? Or was it some
thing instantly needed to be tuned
