My 91 Turq has them. Still work perfectly at 93,000 miles, 368 rebuild about 15,000 miles ago. The engine builder retained them.

Well, just to B different here, mine are eliminated due in part b/c they were smaller than the ports after I ported the runners. (37.5mm+). But, even before the porting, I had Marc eliminate that "feature" after my 2nd dive under the plenum fixing chit (leaks). I've NEVER missed them for a second.

Cool feature for a stock engine. Not much use for them after porting for a full boogie 416, so they are removed.

Agree w Jerry and Paul. I never liked that split second hesitation built into the secondary port activation. Felt like turbo lag.

Both my 1990 ZR-1's have working secondaries, which I intend to retain. My black car has run 11.7 / 118 in the quarter after having the plenum and injector housings ported, but retains the functional secondaries.
