RE: Top end response

[Steven Charette <stevec@xxxxxxxxxxxxxxxxxxxx>]

Rich,
	Refresh my memory, which carbs are you running?

	If I'm understanding what you are saying the car feels like it
"noses over" or stops pulling when it gets around 70mph?  Roughly what RPM?
And I'm assuming high gear?

Thanks,
SC

I have been thinking about my top end performance. I have improved leaps and
bounds in my ET's but my top-end is frozen around 70mph in the 1/8th. It
almost feels like a governor. I'm thinking I may have fuel delivery issues
at sustained WOT. I know I have plenty of fuel available with my new 3/8's
lines and the macho Holley blue 110gph electric pump. 
So I'm thinking that since the carbs are bumped up rich a couple stages
maybe I should put in the larger needle and seats and high perf accel pumps.
I may be lacking in flow capacity at sustained top-end. The accel pumps have
larger nozzles currently but I feel it may need more volume also for the
initial launch. I've ordered the Edelbrock #1980 needle/seat assy ($11ea
local) and the #1982 Hi-perf accel pump plunger assy ($14ea local). I'll try
that out this season and see if it's the key to the top-end.

I was kinda wondering before if my Engine Dynamics 9&1/2" 3000 stall
converter was slipping. In retrospect I think fuel delivery is more likely. 

What are your thoughts?
