I do not run 30-32 degrees on the Elky. Atleast not at WOT under boost. On the highway, yep run 45 at times.
Started this DIY turbo 250 with low timing (25) and increased it with our comfort level, esp with the minimal amount of control the engine had. Ended at 29 degrees. I am sure with a intercooler, the right compression, cam, ect the timing could go much higher. Not what we were doing here. Just trying to show what gains could be seen with a throwdown turbo setup.

Sent out the turbo data, anyone not getting it, contact me. May change to a divided head and intake this evening. We will see how it goes. Tom

Tom,
I see that in all of your pics with the Holley that the carb is oriented 'parallel' to the head. I've read that it should be turned 90 degrees for a more even fuel distribution to all cylinders. Is what I've read been correct? Or did you do this due to ease and the fact that your secondaries are open all the time during the dyno tests.
'Parallel' orientation makes the throttle linkage hookup VERY easy. I say this due to the amount of time and effort it took for me to get my linkage fabricated to hook it up with 'perpendicular' orientation. Which is recommended for a street chassis or doesn't it matter?
Keep up the good work!

For street use, I have also mounted the carb like you suggest. Bellcranks can be very hard for some guys.
With the dyno being WOT most of the time, it really did not matter. It was also easier to hook up the throttle, except for the side draft intake.

Here is the last pic.
Picked up all the parts from the shop. Had them on the truck and thought, perfect moment to capture. You will also see the dyno 292 sitting there. Glad I have a BIG box on the truck.

I heard the Car crafts are all sold out! It has a red mustang on the cover and is the July issue.
My daughter, who usually will not be caught dead talking to me, was very eager to take pic's ( from a lofted up forklift perch). Maybe someday she will think I'm ok. Tom

Drew,
Good point! They were used very briefly at times. Now I just need to get all the parts organized and get the 2nd Elco in the shop. Time to make it power it self. Getting tired of pushing it around. Let those stools collect some dust. Tom
