I just saw the piture of your intercooled Whipple charger and it looks really well done. I too am working on an intercooled Whipple setup, but for an older truck with the 350. And I am using an air to air intercooler. My question is does the added volume between the TB and the Intake manifold on your setup cause any dirivability issues? I have been told that the throttle response will be slower both on and off the throttle due to the larger volume of air in the system.

 

Yes it did cause driveability issues. As long as you can tune for them though, you will be in good shape. Here is what it affected; cold startup and drop in idle speed/engine dying at sudden stops. I have tuned for this obstacle. I don't know what program you would be using with your sbc 350, but in LS1 edit, I added airflow on stops by incresing the cells in "throttle cracker" from 4mph-0mph This keeps the engine from dying on sudden stops. For startup, it likes to hunt for idle when it is cold for about a minute. I have tunned lots of airflow areas and it has gotten better, but still not perfect.

This is all with a MAF setup to calculate airflow. I believe the root of my now very small tuning issues are in the placement of the MAF sensor itself. I think if I were to move it on the exit side of the intercooler, closer to the intake manifold, then airflow calculations would be perfect and it would run without any cold startup issues. (I am in the process of moving the MAF currently -well parts on the way) There was no noticeable throttle response lag at all. Other than those two things, there were only Huge gains from adding the intercooler. I run 11psi on the street with 18* advance and 91octane pump gas

You probably won't have many issues if any at all if your 350 is calculated using speed density and not using a MAF.
Any more questions, ask away.

Thanks, I will be tuning with a FAST DFI system that uses speed density to determine where it is on the fuel and spark curves, so hopefully I will not have the same issues. What size pulley are you running to get to 11 psi?

Here are some pics of my truck

I had to convert from a vaccuum brake booster to Hydroboost to fit the larger compressor

I test fitted the 2300ax in there last week, and I only have one minor conflict point (nothing a little grinding won't fix)

In all, I should have a working setup completed sometime this spring, then I can start playing with more boost.

 

Nice ride It must be a pretty tight fit to have to change the brake booster from looking at those pics. That is pretty clever using the different inlet. I think you have a handle on things
I run a 3.5" pulley to see about 11psi. With different cams and engine etc. the boost will be different.
