Custom Heat Shield – BMW E24

This is a custom heat shield we made for a German market 1980 BMW 635csi E24 w/ a M90 engine. We’ve been working on this for a while and the attention to detail is imperative. This E24 is getting a brand new Super Sprint stainless steel exhaust system. We need to make sure the heat from that is contained and stays away from the fuel tank. First, we took measurements. Then, we hand bent a flat sheet of heat shield material with a flat metal bar. After that, we trimmed the edges to the body contour. Finally, we used our bead roller to roll the edges which makes it much more rigid.

Why you need this?

A heat shield for your European car’s exhaust system is essential for performance and safety. The exhaust system generates high temperatures. Without a heat shield, nearby components could be damaged due to the heat. This shield acts as a barrier. It prevents heat from radiating towards sensitive parts of the vehicle, such as the undercarriage or nearby wiring harnesses. By installing a heat shield, you ensure that your car’s performance remains consistent, protecting important components from potential heat-related issues. Additionally, it helps maintain a comfortable temperature within the car’s cabin and prevents overheating, ultimately extending the lifespan of your vehicle. Prioritizing a heat shield for your European car’s exhaust system is a wise investment in both vehicle efficiency and longevity.

1985 Article about the BMW 635csi

In many ways, the 635CSi is a superlative car. It produces prodigious speed thanks to its new 3.5-liter engine. The 635csi exhibits much better handling than BMW’s early 6-series coupes. It is put together ,vith rare care. Its ergonomics are generally excellent. And now it has Bosch ABS anti-lock braking equipment for help during emergency stops. All told, the 635CSi is a very accomplished piece of work.

Still, we’re talking 3.5-liter, high-rev­ving. seven-league boots here. BMW has punched out the 3.2-liter bore from 89 to 92mm, and the torque has increased from 195 to 214 pounds-feet. This single overhead-cam six is old. but it remains atop the pack in basic design. Its aluminum hen1i head is fed by Bosch Motronic fuel injection. Crossflow intake and exhaust ports handle the breathing. and a new, adaptive Lambda-sensor control sets the fuel-air mixture more precisely through a ,vider range of operation. ·ro allow maximum spark advance at all times, BMW has not yet resorted to a knock sensor, and the 3.5-liter motor compression ratio remains a impressive 10:1. The added dis­placement has bumped up, the horsepower only from 181 to well over 250hp. However, it is tuned instead for midrange response, the big six’s power peaks at 5400 rpm, 600 rpm earlier than in the 3.2-liter. A 3.45:1 final-drive replaces the 633’s taller 3.25 gear, boosting the throttle response throughout the rpm range. but a rev limiter clips the power smartly at 6200 rpm.

T4.5 Eurovan Coolant Bottle Bracket Adapter

We had to make a custom adapter for a T4.5 Eurovan Coolant Bottle Bracket Adapter the other day. We needed a new coolant reservoir for our customer’s 2001 Volkswagen Eurovan VR6 MV. The warehouse sent me the wrong reservoir (Ver C, and not a Ver E). (701 121 407 E). The Ver C is for 1999-2000 Eurovans with a 12v VR6 engine, however all the connections and hoses are the same. It’s just 180º off from the one we needed. Apparently the Ver E coolant reservoirs are no longer available (NLA) and virtually impossible to find. We searched Classic VW parts, eBay and other sites and came up with zero results. Ver C is still available, however it is also hard to find, but they are available special ordered new from Europe. If you need a Ver C reservoir, we can get one for you.

Instead of wasting time trying to find a new one, or installing a used part, we drafted a file in Fusion 360. Then we 3d printed this bracket. Printed with PA12-CF Polycarbonate Carbon Fiber (25%CF/75%Poly). The bracket is safe up to 220c / 428ºF. This will adapts the older C style bottles with the overflow return on the left / drivers side. These other tanks are readily available. Furthermore, this will fit so the left / drivers side electrical connection (coolant level sensor) fits the configuration for Eurovans with the Ver E bottles. Fits 2001+ T4.5 Eurovan / Transporter / Caravelle – 24v Engines, with the bottle that mounts to the core support. We also installed some brass inserts so we can just bolt it right in and the tank can be replaced it in the future, if need be.

Version 2.0

We revised our design a little to make it both easier to print and use less material. It’s just as strong as Ver 1.0.
