The 6262 sillyness is never ending... New cams just got the most power and torque it's ever made

Dale is 100% correct its a well proven fact that smaller cams in RB's aid in response. Even going from a stock cam to a type b pon cam will cost you response. Been many track guys that have thrown the

Looking at a Precision turbo for my rb25det Neo.

From what I've gathered the 6266 0.84 should match nicely. Motor is internally stock but will be running E85.

I'm thinking about spending the extra cash on a twin scroll setup, going to be in a light S15 so I'd want power delivery as smooth as possible.

Any graphs or comments for a similar setup

Hey dave do you have any specs on whats done to the head? Im guessing its got some $$$'s spent on it? As good as the 6466 is dave I would still keep the good old HKS T51R. :) TILL THIS DAY, They still sound the best out of every turbo out there when spooling and cracking that big gate open. Not to mention how farking PORRRRN they look in a skyline engine bay. Haha. How much more do you reckon the t51r has left in it on your setup dave?

At this stage piggaz has talked me into going a pt6262 on my built rb25 with a r33 gtr 2.6ltr crank in it. After seeing all these 6466 30/25 or 30/26 setups making such grouse power makes me just want to build a 30 bottem end and go 6466.

I'm pretty sure it's just a basic build.

Forged pistons and rods, drop in cams etc.

TS 6466.

We went out on a cruise sat night with a few other big HP GTRs and this thing annihilated everything, every bit as responsive as the graph suggests.

Richard had to drop the motor as it was sitting too high and the plazmaman was hitting the bonnet, I was there on Thursday dropping off some E85 and Richard said that it was due back from the exhuaust shop later that day then they had to drop the engine and finish off some of the connectors and a few hoses here and there and then it will be ready to start and hopfully tune. He said should be ready by mid this week

We'll, forgive me for being a sceptic, but I need to see a timeslip or data log to believe. This thing still makes 200 ftlbs more than I thought possible and spools earlier than a 35r. Crazy!

When I had a GT35R it was on song (26psi) by 4400rpm. This thing is laggier than that, id say T04Z territory.

These aren't a big turbo physically which is surprising to see what they produce. Looks like a GT35R from the front but the rear housing looks quite large.

The blade design on the turbine side is also something I haven't seen before, it is like the blades are convex. (if that makes sense)?

Just to add, I have seen 2x SR20VEs with these turbos making more power and on earlier than my T51R KAI RB30/25.

One ran 154mph and the other 148mph, both 5 speed H pattern cars.

      With my pre/power I use a remote trigger cable(3.5mm jack each end). I turn tv on, it turns both on via ARC. Or, just the pre with the remote or its streaming software, turns on both. Not that difficult at all. Obviously,  you would also want to actually update/upgrade over other factors in your life(bills, family, other hobbies, etc)

      Yeah, nightfall was very "meh". And I'm crap at pvp, so feels like everyone has cheats(it's just my lack of skill). Final shape has been pretty good. New raid and dungeon are pretty good. If you want to give it a go, probably wait until it's on sale. But, as usual, most of it feels very familiar.

      What Music Are You Listening To?

      This morning was Kingswood's Microscopic Wars. It is the album's 10 year anniversary this year and we went to see them play the whole album as a special show a couple of months back. Was pretty spectacular.

      Thinking of getting a Q50 300hp and just tuning it instead of getting the Q50 Red or 400R

      Yeah I would like to try and get a ADM car to reduce issues with insurance. I've decided if I end up getting this car I will set it up to be a sleeper build, leave it looking stock/dad spec on the outside I wonder if you can just drop in the 400r/Red/Z ECU or better still use a flashing tool to copy the map off one. Backup the factory map and then flash the 400hp cars onto the 300hp cars ECU?

      Nah, yeah, nah. Speakers have a nominal impedance of 8 ohm that looks more like 6.4 ohm when measured. The receiver's amplifiers (all channels) are all rated to 6 ohm (I think, it's been a long time since I cared). The real problem is that many modern class D amps have aggressive protection circuitry that cuts off the fun if they think too much current is being drawn. And with my speakers having series crossovers, as opposed to more typical parallel crossovers, and big TL enclosures, they can certainly dip down to lower impedances at some frequencies and that easily triggers the protection. Pioneer receivers are somewhat famous for it, but even Denon, Onkyo, et al, all have many complaints against them across various models. It only does it when listening to music at high levels. You have to be putting your ears at risk to do it. But sometimes I want to do that. If I was serious about using it as a listening room I'd simply upgrade the amp for the front pair to a nice Rotel or something, and just use the receiver for signal handling and processing - although that would be a bit of a pain in the arse too. Have to switch on more shit, pre-amp volume vs main amp volume, etc etc.
