I did run an extender on both front O2 sensors. But the car was running / idling great in this configuration for around 500 miles while I was breaking in the clutch.

AFRs at idle are right around 12-13 on my wideband in open loop at first start up before going into closed loop. When Vengeance was road testing, they said they tried an open loop tune but noticed the fuel issues were still present.

I've never driven a centrifugal setup before this build. My old 04 cobra was roots style with a very flat torque curve, more on / off. The experience is unique with the linear power. It drives like stock until you put your foot into it and start building boost. I don't really want to fully wind it out on the stock block, but driving around town is a blast. And the lightened flywheel is great around town. It's nice to be able to slip the clutch like stock and not have the shuddering like a single disc. The idle is also set at 1000rpm and it has almost eliminated the clutch chatter.

Still noticed I'm dripping a little meth from the nozzle which stops about 1-2 minutes after parking. May need to see how to remedy this, I've already tightened it pretty hard.

Also planning to have a custom charge pipe made at some point to clean it up, now that it's SD and can eliminate the MAF along with some of the couplers / clamps.

Not sure on the nozzle size but I am running single nozzle, which ever size came with the A&A kit from Alky. I'm wondering if I should upgrade to the dual nozzle down the road at this power level?

You should be well above 800 then if you're running a 3.6 and 10% OD plus heads. Keep us posted!

It ends up being a nice small part which can vibrate loose and catch the breeze down into your cylinder. (!) So it is worth loc-titing the heck out of the bugger. If I still decide to run it again on mine I'm going to toss a spot weld on the tip just to be certain. I'd rather have a fugly charge tube than nuke my block.

run pump gas with the stock ecm on the primary, and a much larger injector controlled by a Megasquirt or something with widebands

just a smart direct port meth injection. I'd need enough monitoring to know if the meth goes out and running like crap works fine too!!

haven't got much feedback on this idea, sorry to jump on the thread

If done correctly, you lose a large enough of a fuel component, it will be enough to knock the engine on its *** without doing any damage and it'll run badly enough to where you should know something is wrong and let out of it. I also set up the tune for secondary protection. I custom build upper charge pipes to eliminate the MAF. Let me know if I can help.





I know that you know this but to help clarify for the OP and others, at the junction he circled, It's pipe thread on one side and AN on the other and then NPT between the nozzle and fitting at the charge pipe. Definitely use red loctite on that nozzle.
