Changed a few thing and having a hard time building boost.

[Mr. Rollin Coal]

So here is a few things i have changed since i noticed the slow spooling. I rebuilt my turbo and threw a 66 comp wheel and cover which used to be the 64 super b special. I also put an aftermarket ex. manifold that i mildy ported. Ever since these changes i have a hard time building boost to do a launch. It feels like im trying to spool an s400 framed charger. Would the 66 wheel and new manifold cause it to have a hard time building boost? I am open to any input of what you may think it could be.

 

[Mr. Rollin Coal]

Did a pressure test today and the intercooler is leaking. Thinking of getting a bd

 

[LReiff]

Are the manifold and turbine housing divided? Did you use a divided style gasket?

 

[Bponci]

A ported manifold will slow down the exhaust velocity. Did you machine the center section of the turbo enough to accept the larger exducer diameter?

 

[Mr. Rollin Coal]

Yes they are both divided and I also used divided gasket that I port matched.

 

[Mr. Rollin Coal]

The wheel was machined to fit the original center section which was a 64. I bought the wheel and cover from dzlfreak.
