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?

My advise would be to buy new intake manifolds from Whipple for Port injection. This will help with fuel distribution. Running the fuel through the blower from the throttle body usually loads up the front 4 cylinders with fuel and leans out the back 4. I know bc of hours on the dyno with both set ups. This will also help docking manners and make programming easier

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. 🥴

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.
