These are fact and thank you for posting up! Looking forward to seeing your car in some serious action very soon!

Thanks Larry, you going to the event June 9th?

Hey Drew. Just saw your videos on YouTube! I'm glad to see you back on the road! I know your having a blast! I'll be on the look out for more of your videos.

Congrats to ESS for steping up and building the VT3-725! Great job!

Mike, really appreciate that Broski, glad to see you still posting here! I'll get more #'s and vids soon.

Haha thanks man.

Beast Mode! Must be hella fun to drive.

congrats Drew... is there a possibility of increasing boost beyond this current setting since the motor is built? >=)... mo powah! hahaha

The motor and fuel system will easily handle more boost. The limiting factor at this point is the stock DCT transmission. We set the power where we felt the tranny could handle. We simply do not know it's limits at this point so we will have to see how it holds up.

i figured that would be the only weak link at this point... good to know, thanks Roman!

One step at a time J , try not to focus too much on peak # comparisons, the car up to 7800 RPM's is making 50-70 more whp throughout, after that it's 30whp Meth vs. Meth, with No Meth vs No Meth, it's making 50-60+ all the way through vs the VT625 kit.

On my VT625 meth dyno there is a power spike right at redline that skews the differences a bit, and on the VT725 dyno, for some reason it drops a bit up top, on another dyno it did not do this, and made 644whp STD, but we wanted to use the same dyno for comparison purposes.

Either way our goal initially was 725 at the crank, and we've done that. I will get a SBS run with a VT600+ at the Shift-S3ctor event. Or possibly a run against the Arkym VT650 so you can really see the difference. Eventually, depending on the transmission, we may turn up the boost more.

Goddamit Drew, you my hero! I'm coming to the US in June, I wanna' hook up with you & talk some smack if you free.

Haha, good to see you posting over here! For sure let me know when you're here.

Send over your Vbox run (see link below for email) and I'll put it on the list, congrats on a great time!

Hope you can make it as well J.

what i find most impressive is that these figures are only at 11psi , i wonder how much izzy will put down since he's 6MT and if he can run more boost somewhere along the lines of 14psi ...... i wouldn't be surprised if 650+ whp is achieved.

Drew if and when you run the Arkym car run it with Meth off and on it would be awesome to see the difference

Will do Jamie.

Drew the 650 in DCT format is Bonkers !!!
Amazing on how I've been missing out with dct power delivery ...

Videos of the Schrick cammed S65's you got there or ban lol. I wanna hear those things

Sorry for OT. Drew sick numbers brother. How's the low end throttle response BTW? That's the only thing that i don't like about Turbocharged/Centrifugal SC'd built motors.
