Won't rev without the AFM plugged in but they do fall in a big hole if you open the throttle, his doesn't and that's what has me confused..
(be cool if that's all it is)
Sorry never owned a stock GTE and was going of my old GE AFM...
This one has me stumped and why I asked Tweety to post a thread on it.
I can't even think of a way I could make an engine run this way on purpose.
Made a bunch of adaptors over the years, only time I've ever had an issue was when I used what I assumed was flat material and didn't surface it both sides... :(
I mean mechanically jammed as in the flapper won't move and it's choking the engine (or there's a rag in there somewhere)
There is 0 throttle response, usually if it's a fuel/spark issue it'll fall in a big hole soon as you open the throttle.
Tweety PM'd me on this one and it's something I've never seen/heard of before but agreed if the AFM was somehow jammed shut the engine would behave this way!
Click the pic it's a Vid Link!
Mag test cars topped out at around the 130mph back in the day when the cars were fresh, you can bet the test cars were prime examples as well.
Mine was a low mile example well maintained and tuned and never got past 128mph on the flat.
Can't see how you could do it with any degree of accuracy/surface finish, there are a bunch of spots from memory you can't get to at all, at least with Power Porting (extrude hone) it's a uniform material removal from one flange right through to the other.
You can only get a couple of inches in from either end so it's a waste of time and effort...
Look into "Extrude Honing" if you're at all serious about porting a stock manifold to get some real gains.
