[Nick.Hay]

B10 engine??

First time for me.

The clueless need explanation. Why does it look like its glowing? Is the fact that it appears to be glowing related to it being alpina? Sorry to be so stupid, but I need someone to tell me the point of what I am looking at.

Alpina B10 Bi-turbo engine on a test stand running its heart out. Heat from the work raises the temperature of the entire exhaust and turbo housings to glow red. Talk about a stress test...

It's glowing because it's turbocharged ... very. Compressing all that air creates a lot of heat.

I haven't seen this pic, but I've seen similar ones from Saab's early turbo development thirty years ago.

if you ran any engine at full throttle for a time the exhaust headers/manifold would be red hot,the exhast gas temps are like 600c

Indeed, see link for S38 headers aglow:

It sounds like Whit has plans for something like that atm. With 6500rpm one can get 500hp. As the BMW racing team did back in the 80s, by heading for 7500rpm or they claimed 950hp with those old KKK27 turbos and Kugelfishcer injection.

Rice or no rice, the e34 would need some serious wings- and would see upwards of 300km/h... now that would be unbelievable... and worth putting up against a modern M5
