I think that we should double what we have and have a custom intake manifold maxed out with double the injectors!!!

BTW pretty sure that the Bible strictly says that you will not know nor will you know until it happens for rapture or "end times" only he knows! I guess he miss that part of the scripture readings in Revelations!

too late to tell him now he spend all his money on the Billboards.....

BMS tested an off the shelf KB boost-a-pump and it helped extend the fueling range up to around 510whp with a reasonable air/fuel ratio. At that power level they are finding automatic transmissions don't last long so the fuel system testing is on hold for now. More power won't do you any good if you can't get it down the track without blowing out the transmission.

Explain why 6AT's don't last long at 500 hp. LM hasn't had an issue yet and neither have the guys running no2.

Can't answer that but LM, Hotrod182, and BMS have all had major transmission slippage at higher power levels. I'm not sure how many other 500rw+ cars out there but perhaps they can chime in with their experiences. At that power level the manual trans may hold up better if you can find a clutch to keep up. We'll see as more of those guys hit the track.

That is interesting to know. I would be interested to see how the boost a pump affected my AFR at my 525 rwhp level. I have a bear of a clutch that will hold a LOT of power.

You trade in your AT for a MT and you're done - less than a day's work
