Injector mounting in manifold.

[Cody]

Naw, Jim, they are talking about TBI backfires. TBI does indeed backfire, but I've never seen it do any harm to anything. At Black Forest I once had to work on this 911 that was the most terrible thing I've ever seen. It was a 930 (early 911 Turbo), but the turbo was removed and replaced with aftermarket NA car headers, and it had some god-awful terribly made home made intake manifold with a Holley Pro-Jection throttle body injection setup. Still sends chills up my spine just thinking about that POS. It was tuned terribly, and in the tuning process I occasionally had it lean and yes it would backfire quite loudly, but never did anything outher then leave a carbon deposit on the injectors and TB.
