Thanks for the dyno sheets. Perhaps my search skills are not leet enough at this point.
It appears the stock motor cars make great numbers to redline. Do you have any of the built car dynos that run out to 7000rpms? or higher? Since searching owns me and you have these all somewhere, I can wait for you.
It appears double posting owns you.
EDIT...Whoa, I know I saw a double post. How did you do that?

Scott, thanks again for posting those charts, I know I had seen them before, but couldn't find them to answer some of the doubters.
The second stock dyno with 320 ft-lbs of torque at 2000 rpms is impressive enough, but how did that other one get 400 at 2000 rpm, it's within 20 ft-lbs of the max. That's amazing! Any difference in other mods?

3000rpm = 230/397 hp/tq

APS:
2000rpm = 99/268 hp/tq
2500rpm = 152/318 hp/tq
3000rpm = 198/352 hp/tq
3500rpm = 238/374 hp/tq
4000rpm = 298/400 hp/tq

6500rpm = 400/325 hp/tq
He did a test of all these kits for a write-up in the Sport Z Magazine. So it's the same day and same dyno for comparison.
I also wondered about the drop-off or the fact that VRT seldom publishes charts over 5800 RPM, definitely makes it look like they are hiding a massive drop-off, however, this third party test seems to show how much torque it maintains, better than the APS and very close to the Greddy at 6000+ RPM's.
However, if you look at the lower RPM numbers, the JWT kit blows them away for torque.
All this to say, if you aren't planning on going for really large RWHP numbers, the JWT kit should be able to hold strong all the way to redline, and have the advantage of extra torque at the low end.

Hell, on my G35C that makes around 800 WHP, I can't run that high of RPM without erroring out the Speed Limit Controls on the dyno in 6th and in 5th the car can't get traction. And yes my ECU is flashed.
Nothing to hide at the lower 6000 RPMs, just not fans of over-reving. Just causes stress that isn't warranted.
Goodluck with your quest.

Yeah this is an old thread, but...
I am effectively going JWT-kit with my VQ35 (JWT exhaust manifolds, GT25R turbos) and this thread I find very helpful. The lower RPM torque numbers KILL my current VG30DETT and I have the smaller, quicker spooling turbos from an automatic Z32. AT 2000RPM the JWT VQ35TT is ahead of my VG by a massive 170ft-lbs and is at 2500RPM is making more than VG30DETT's peak.
Amazing the difference 500cc makes in spooling a turbo.
