I would be surprised if it runs 10.2. Way more then 820 needed with our cars and weight and transmission to run 9s

I think this will depend on if they tampered with the TCU torque limits or not.

Well, looks like we will have some pretty interesting numbers to look forward to this year between these and the pure turbos.

I have my doubt's about 9s though

These cars will never have the 60' or 330' foot to run a 9 with MCT lockup logic and torque limits. Until that is cracked with a combination of HW and SW, don;t hold you breath. Also I would expect more than 860whp on a built bottom end and w4. Pure stage 2, with meth is already close to that.

EDIT: that 863whp was on 91 pump....ok..I'm impressed! Race gas, or meth with more timing we should see close to another 100whp

kit has been out for a while and W4 car down here was supposed to put up dyno 3 weeks ago and still nothing.... weistec had their W4 car at shiftsector a while ago (after it posted its first 830whp vid ) and ran 165mph, so definitely not a 9 sec car

almost a year since their 830whp vid and no dyno's from weistec and no official times, plus customer car down here that was all over instagram with his w4 build and then once it was finished, nothing... no dyno (even though they were "coming soon" 3 weeks ago), no timeslips ..... if the results were impressive i am sure we would of heard of them by now

So torque is less than stock turbos and 200 more horsepower

Can't even imagine what that would feel like.

At some point, the W4's have got to make more torque than stock. Hp = (torque x RPM)/5252. It's most likely making it up higher in the rpm range.

Larger turbos move the torque curve over to the upper rpm range. It makes more torque up top and that's where the HP gains are.

lol stock turbos don't make 760 wtrq in the real world ... on an inflated corrected Dyno maybe ... or maybe for a split second Dyno spike

and stock turbos only make high trq for a small rpm with window and then run out of breath whereas bigger turbo holds that trq to upper Rpms thus higher hp

these bigger turbos should make it much better for highway pulls but still do nothing for low end launch.... so you will still get smoked by m5/ RS7 at the stoplights

rs7 from a stoplight I can understand as it launches hard with perfect traction.

Even with a slight lag that we have I don't see how a RWD m5 is winning an AWD E63 from a stoplight on street tires
