I typically rev mine to 9200. The power carries well. The 6262 car revs to 9k. I usually don’t rev cars much higher due to rpm limitations on the accessories. I think the valve spring is a bigger concern than the cams to keep those valves from floating.

Installed straight up. Shifted the power to the right.I also tuned a 2g that made the same switch from Kelford 272s to S3s. 6262 car at 35 psi. At the same boost level, the car went from trapping 138 mph to 145 mph in the quarter. Our only change on that car was the camshafts. It carried the...

Here’s mine making 894 to the wheels. 6466. E85. 50 psi tapering to 44 by redline to manage back pressure.

The dragys are not a great way by themselves, but pairing them with other data helps add to the picture.With the clutch deal, I actually have it set up as timed through my haltech and not “as triggered” which helps keep the shifts much more consistent and not waiting to see the clutch at the...

so far I’m not impressed with the t3 housing on it. Speaking with Joe from FP, it sounds like they’re just not a good hot side compared to the tial but that’s why I’m looking to switch it up to the vband housing. I think in a stroker, the .85 AR would work better but for my 2.0, it just lags...

Alright, so I've been doing a little testing and trying to get as much "back to back" testing as possible. Something to note ahead of time is that the testing between the 6466 and the 9569 were done in similar weather whereas the testing done on the 9564 was in weather that was 30 degrees...

Ill post some logs and data here soon but my shifts vary from .18 to .28 seconds. Thats from the time the clutch switch disengages to the time its engaged again. In that time, the turbo drops to around 21 psi of boost. The 6466 dropped to 41ish. Flat shift is WOT with 100% ignition cut. Im going...

Here’s some data so far too. Ive only had a few days of testing so far. Slightly skewed because 9569 was tested on a hot day with negative slope but I think between the DA change and the slope correction, it might cancel out. I can see the 9569 clearly makes more power, but it also drops...

Here’s an update but with questions. I just removed my old .82 AR 6466 and replaced it with a .85AR xona 9569S. 6466 made 50 lbs of boost with the wastegate dUty cycle 45% ramping to 100% by the end of third. Now that im running the 9569S (67.9 comp ind, 69mm turbine exd) im finding that with...

The item Barn Find Sleeper has been updated:Figured its been awhil but not much has changed other than the amount of data i gathered from this car. Making the switch to a xona 9569S really soon. Id like to see some more improvements here!

Honestly, my biggest goal is to maintain the spool factor while hopefully increasing my efficiency. The Gen 2 6466 is quite old so Im hoping the new tech, like in the UHF wheel, will shine with the 9569. Im going with comparable hotsides, .82AR T3 with the 6466 and .85AR T3 with the 9569S and...

Thank you. Yes, that's my car. And actually, I got my 9569S from Josh W if that's who you're talking about and I believe it is. I've heard good things about the UHF wheel but I guess I want to see if for myself. If I can see 50 pounds in third by 6k rpm and make more power, I'd be a happy...

Thank you! I was just happy It didn’t break. I ended up putting almost 1000 miles on it that week and didn’t touch anything other than emptying the catch can.

I know some of you guys are running the 9569S. I’ve got the 6466 and looking to stay T3 for street car reasons. I’m curious if you’ve used either turbo, how would you compare them? Otherwise if you just use the 9569, how do you like it? Any information or data on the UHF turbine wheel design...

Just curious, who here has a high horsepower fully wet block? and what do you make (hp and dyno type) or trap? Looking for personal experiences please. And for those who have half fills and street drive their vehicles, how do you like it? Do you notice any overly excessive heat anywhere? I've...
