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.
