Had a so-so day at the Track yesterday 4-9-17 .
Various problems on 2 of the 4 runs , so only 2 were decent .
Bright blue sky , and about 80 deg .

Running the Evans intake . Pretty sure that it will be an improvement in the long run , but a
Carb problem has interfered . The " stumble ' at the hit , which I thought was gone returned .
I'll do a total carb rebuild etc . ( I really did not want to do too much for this event , because I wanted
to compare Apples to Apples .)

Results were mixed. MPH is pretty good for this car , and the 60 ft times were good also , especially when considering the
stumble .
60 fts were 1.991 , 1.865 , 1.878 , 1.870 .

2 Best MPHs 94.80 and 94.52

2 best Ets 14.125 and 14.057

As I don't qualify to run in the fast guy lanes , I am surrounded by a horde of various Hemi powered Dodges , and new Mustangs , with a few
Turbo Subbies and the like over in the " street class " . But , I did win one out of my 4 runs , somehow .

It's always interesting to see your reports. One fine day everything will work like you want it.

As you might know, depending on the plenum size difference between your previous vs. the Evans manifold, a larger plenum will require a larger amount of fuel to enter the plenum at the hit of the throttle. A idle fuel (mixture screws) increase will also help.
A lot of times, even a couple of degrees of ignition timing help.

I did basically anticipate that , and set the idle a little on the rich side . The Evans is a single plane , but the Morgan is a dual plane , but
I had a quite high spacer/stack on it , and a good bit of the divider was cut down also , so had a goodly volume in there . The problem was there
to an extent before the intake change , but I thought that I had tuned it away with the idle set and making sure that the stroke of the pump was the quickest .
It had not shown up , or been noticeable before late last year .
Will be ready to move the timing , depending on results .
I'm gonna do the carb , verify the metering rod movement etc etc , and go back whenever possible .

Thanks for the comment .

Hi Bill,
What car and carburetor are you running? Air cleaner? Open exhaust or closed? Distributor? Plugs? See where I'm going?
