Finally made it to the first goal. I guess depending on how one claims numbers this graph could be interpreted peak torque at 470, but better off claiming the solid linear torque number. So it made a solid 434/401. So happy to say its the first 2v / M90 to beak 400whp.
Meth position is working great but the last two runs the fittings by the nozzles started leaking quite a bit so ACT's started to suffer on the last two runs. You can see the leak on the pull on this vid. It's a little hard to tell on this video unless you make it bigger, but it leaves a puddle on the intake.
First runs finished WOT pulls at just over 130*. The last two power pulls ACT's went up to 169*170ish*, which is still good temps considering the speed of the blower. This meth/water position is definitely good for at least a 60* drop in ACT's. I used to see 195-220* at only 16,000 blower RPM's and its now spinning at almost 20k and its down to a solid 130's.
Snow makes new fittings that fix the leak issue.
Had no belt slip. On the above pull it made 9.0psi at the 470 torque mark, and boost kept rising and peaked at 9.3psi at 427 torque. The 434 torque marked on the graph was making 9.2psi.
Made 401.4 rwhp at just over 5,600 rpm's @ only 9.0psi ! WOT was cut at 6,200 rpm's making 390rwhp and boost actually went up to 9.2psi.
So this pulley combo is definitely a success, as is the meth/water position.
These numbers are sound and solid as it accomplished the above pull with very heavy 20's that weigh 44lbs per side on 295/40/20's, about 30* hotter ACT's then the previous about 5 pretty much back to back pulls. Great part about all this is that it was accomplished at just 9psi. This Magnum Powers case and port matched intake is flowing nice as I used to see 9psi with my old setup and spinning the blower at just 16,000 rpm's.
Next pulls will be with light wheels and tires I will use for the track, and about 30* cooler ACT's. I think the fittings progressively leaked more because at first they were solid 130 ACT's and got one as low as 115 on a 5,500 rpm pull, that one was good for about 125* at 6,100 rpm.
So as Charles from Magnum Powers said, if I can control the heat, this case will make power as fast as I can spin it, so far that's proving to be right.
Next goals are fixing meth fittings, wheels/tires, changing my rear chiller to a "real" ice box. Once all that is in line ill start raising the boost. Considering how well the motor is flowing I expect to now see about 12.5 psi going down to a 2.25 blower pulley at just under 24k blower RPM. Will it start to slip out of control? There's only one way to find out. If necessary I could go 10rib with little effort.
But for now glad to say the first goal was accomplished, and can now ease into what's next. But im predicting mid to high 400's in power and over 500 in torque next to come.
Thanks Charles for your support and help for making to these numbers. Scott great little AED kit you built for us. Bruce and Derek from JBA, awesome job with the tuning and making these numbers real. Lonnie for your countless hours in working out this unique tune from the very beginning. John @ MP can't say enough about the motor, and Snow for your great product and support. And can't forget Kearney Mesa Welding for the great job on the intake work. Also thanks for any helpful tips to the members.
This was done on 91 pump gas.

And I hope you are taking it up to at least a 408 stroker, forged with some AFR 205's? 
How long before you finish and install the motor?
