Pricey, but arguably worth. Almost all the Supra exhausts are actually just 3.15" of flow because they're designed to hook up to the stock DP with the 3.15" diameter squish at the outlet. That squish limits maximum flow to that diameter.
This exhaust ppears to be a true 4-inch, and afaik there...
Broski: if they spent $60,000 on a car, joined an enthusiast forum to talk about that car, and still can't figure out what they actually own... I'm not sure pictures will help.
You're correct. Thermal management is easier down low, as the engine and engine bay are designed for the turbo in this location. It also makes for a comparatively easier install (IMO) as all the hookups for the turbo are down there as well, and you can re-use the EWG if that's what your setup...
The soft DTCs are normal, but the real code people are worried about (ASE code P0420 and P0410) actually cause a CEL on the dash. That's what people are trying to avoid.
In fluid dynamics, flow of a system is limited by the narrowest point. If his exhaust attached to the stock 3.15" restriction of almost any downpipe, then flow and backpressure is unchanged.
I'm definitely excited about it. I've been largely unimpressed with the turbo offerings on this platform. The bottom mounts have been underwhelming (lackluster components), and top mount is not a use case I want anything to do with (not the spool characteristic I want). RP is the first solution...
I absolutely love the T51R sound. I understand and appreciate it's controversial, but I run an RP turbo with T51R on my other car and it's currently the stock block record holder for the platform. I loooove the sound of T51R.
But it's like fuel dump on timing retard. Some love it, some don't.
Anyone with a passing knowledge of turbos should have seen the red flags around CTS.
1) Their power claims changed several times, and later fell apart under scrutiny.
2) They scraped the parts bin for old-gen GTX turbo parts, which are known to spool slowly and flow poorly.
3) They couldn't...
I don't think it's about promising the world, dude. Just about being realistic. It's not another bog standard header/vband/turbo setup, so it takes more time. ¯\_(ツ)_/¯
As a sidenote: their turbo ODM is the same as Garrett. Yes, Garrett does not make their own turbos. They license ODM...
It's a long wait because the product does something others don't.
1) It reuses the EWG for easier tuning, even with a significantly larger compressor housing. That requires unique R&D to relocate the wastegate actuator without binding. The compressor housing sits notably further away from the...
