I don't ignore any part of optimization.

This also applies to car aero.

We had splitter strength issues at 220mph so I simply suggested we remove it and it's been fine over 260mph.

Your results may vary.
Boost fell 3 psi and power cam up to the tune of 60whp is what i was told by Eurocharged. we had a new pulley made to get boot back up to the 11psi we had been running before the heads. I cant post anything official until i have the dyno sheet in my hands.

I like that you're tapping brains outside the MBW community for help with this - I was the guy that got to push your car around the staging lanes for Jake so he wouldn't heatsoak just pulling it forward

Post as BenzoDoc elsewhere btw.

Any time you're running WOT for 28 seconds your tune and fuel are going to be paramount - I assume you're running a modified version of the tune that Jerry made for Brooke, right?

You running an aftermarket fuel rail?

IIRC they ran the car in full trim weight wise, I'm sure that you can probably cut a ton of weight out if you wanted to, but ultimately aero should matter exponentially more than weight.

A lot of guys that drag these cars with the 180+ pulleys pull their front grille out for cooling reasons - but that would definitely adversely affect your drag coefficient.

well you know like i do there are maybe 5 people in the whole community that know what they are doing and Jerry and Jake are two of them LOL Im holing that the rear tank and IC sprayer along with the ported heads solve the heat soak issues. I never intended for this car to be a race car by any definition but i looks like its going in that direction. I just got word that that issues have been resolved so it should be on the dyno very soon.

I hope to have dyno numbers soon the car was supposed to be dynoed today but i didn't get a call so i guess not, the car is not daily driven.

You need to move a lot of water to keep an A2W IC cool during long stretches of boosting.
The car has a Roots blower so a large air/air intercooler is not an option. I have the largest heat exchanger on the market along with a rear reservoir (with two pumps) i also have a intercooler chiller attached to the heat exchanger.

Do you have any type of water temp sensors in the A2W system somewhere to tell you if the water temperature is rising too high? What are your intake air temps at the throttle body (or at the manifold)?
the system is split from the cooling system and i monitor Intake Air temps. the tank is 5 gallon and the lines are 1/2" braided here are pics from the first page
