Changing to the electric high volume/hi pressure pump lowers charge cooler temperature. Avoid Bosch xxx 002 weak pump. On this diagram, Bosch 392022010 is the first acceptable pump, all below = junk.
Chargecooler resistance dotted line determines where your pump would like to work.

Be sure to double insulate at least the bottom and side of the exchanger with layer of Thermo-Tec insulation and Nimbus GII hard shield, sold by Merlin Motorsports or DemonTweeks.

All who have a large 3" OD exhaust with 6" dia round Langford resonator, don't have to "improve" anything!
I have inserted an endoscope to inspect the guts of the system and discovered that the resonator (not muffler!), is a 3" trough-and- trough part with perforated inner tube, no baffles. It looks very similar as an inside of the Magnaflow resonator. I don't know if it is a fiberglass or steel wool media.
Nothing to improve here, except weight, perhaps.

All later 90+ MY had an oval muffler, 33 lbs anchor.

Rear Hub Bearings, Esprit w/inboard brakes

Reference: post #139 of this thread.

FAG545495AD Wheel Bearings are made in Slovakia.
It x-ref to SKF 99905303500 (blue seal) made in Germany = better metallurgy and reliability

I found a much better Lava Titanium blanket (olive green inside and outside), which has a silica fiber on the inside.
So far-so good, it keeps the compartment temperatures reasonably moderate.

Search on eBay for: 1320 T3 Titanium Turbo Blanket Heat Shield Barrier Turbocharger Cover Lava
So I guess this $19 version is the one that burned out really quickly?

They certainly have a great products!
I heard, that the customer service is slow, but their innovative technology is worth the wait.

The R line compressor is 7-14 vaned and features a thin slim hub to maximize airflow and extended tip technology for increased efficiency at higher pressure ratios. The R line compressor technology was designed with larger exducer diameters which will increase hp output at higher engine speeds. The complete R line compressor technology is now available on our complete line of CT turbochargers.

Why you want Twin-scroll Turbo?

FYI:
Great article explaining advantages of the twin-scroll turbos:

https://dsportmag.com/the-tech/twin-...-great-divide/

https://zilvia.net/f/showthread.php?t=460807&page=8

If I remember it well, Snowrx is the first Esprit Owner who has installed Borg Warner twin scroll turbo on his "Red Rocket"?

Having that color blindness thing again? British Racing Green

Also I would not call it a "rocket", (or race it against my Subaru). I went with the EFR turbo as it looked to be the best option for responsiveness, and I wanted to convert to an internal wastegate to add lightness and simplicity. I'm not willing to bet my transaxle against rocket-like levels of boost.

Gimme a Audi or Boxster transaxle and the laptop could probably throw on another 75 hp....

OOOPS! I stand corrected, the Green Bollide, that is!

Have you made any improvements to your tranny? At least Quaife and/or my reverse cut CWP, (LOL), distributed by Harry?

[QUOTE=Have you made any improvements to your tranny? At least Quaife and/or my reverse cut CWP, (LOL), distributed by Harry?[/QUOTE]

I put in the Quaiffe with new carrier bearings, added a magnet to the drain plug, replaced the circlip, added the big crank pilot bearing, rebushed the linkage, and gave you a Paypal deposit on your CWP project!

Bollide is a bit too close to the truth, as the last head gasket failure gave a hot fart that ignited some roadside grass! My wife therefore prefers Dragon.
