Mine will do it guaranteed on my street tires. I've even had it happen with ET Street R's that had 25 psi in them (so I could drive cross town with out the "wiggle").
People with balls big enough to send it and time.
Eventually we find out what the motors are capable of holding over time with people pushing the motors.
How is Lund handling the meth? Is he just letting the car trim the fuel on it's own since you are just using it for cooling, rather than writing a specific tune to account for the added fuel?
I really wanted to give the Paxton a go this season for SCT events, but you are making it really hard...
Turbo is going to have a big TQ hit when they come online. You can see it in the dyno sheets with the bit TQ swell. Centris are similar, generally with a less dramatic "hit". PD cars are the closest thing to "NA big block" feel other than a well tuned progressive nitrous controller.
Tires will...
Cornering, yes. Hard accell, depends on fuel level. I always ran at least 1/2 tank at the strip in my 15 with an open hat. There are solutions though. You can run a surge tank and that will eliminate starvation due to G forces.
I run a boost reference to my regulator.
At 0 vacuum you have 58psi pressure, so that is what your injectors max flow potential is at a given duty cycle. Add 15 psi of boost to the manifold and you now have 15psi of pressure working against that 58psi, so now you are working with 43psi of...
That combo would be massive overkill for his setup. If he doesn't mind doing some custom work, a GT350 return style setup can be pieced together for less than $600. It only depends on your hose/regulator/fitting choices as the main cost. The pumps are only ~$180.
Get a good quality gauge and be done with it. I prefer one with a peak recall and output for logging as I can't stare at a boost gauge while trying to keep my car pointed in the right direction.
Deatchworks has their new pump out that flows way more than the Walbro and can be had with the proper venturi outlet. They have already been retrofitted into GT350/500 hats, no reason it wouldn't be a drop in type of install for the stock single pump hats. It would be more than you need without...
