So what are you doing about engine management, computer, EFI control, etc?

I thought you just went through this with the Holley conversion?

Are you starting all over again or do you use some of that system?

Where do the fuel injectors go?

This will also help docking manners and make programming easier
I think eddy young said it had problems side to side, but what you said seems intuitively correct due to the small discharge area compared to a roots.

Thanx!

We pulled in there about 3 am slept in the boat and finished the rest of the ride on Saturday .
It was a working vacation with prop testing from FJ and then getting the Whipples.

not sure where all the heat talk comes from. My NA 540ci in my car has IAT temps similar to your roots blower setup. Guys need to calm down with the heat talk. 🥴

You should get an intercooler , sounds too HOT!

My Vortech supercharged small block would have ait's in the 170-180+ just cruising around. Under boost would be 200+. Ran like that for awhile, than put meth kit on.

My single turbo setup on same engine would be cooler cruise temp but over 200 under boost. Put largest intercooler i could fit and now air temps are much better. 5-10* higher than ambient after 1/4 mile run.
