Is it worth fitting a Tappered 70mm->64mm TB to a stock'ish SC setup 7psi like SOS, RPM etc?

I'll be running 7psi, AC, TracySports header, 5zigen singlepipe, Comptech fpr and VAFC2 - this is just to begin with.

But i wonder about the performance differences? and maybe the above setup will too much to handle fueling wise?

I read 10BHP at the wheels but is this really true and applicable for my setup?

Thanks

 

i wouildnt worry about it personally right now. if you want 10hp, up the boost 1-2psi

i would worry about injectors + standlone + more boost before i did a TB

 

Ok thanks, I won't be upping the boost
anytime soon though.

Anyone else care to Chime in?

 

Our throttle body has been independently tested to produce over 10 wheel horsepower on even standard supercharger setups. It is probably the best $/hp mod you can accomplish. Here is some further information:

Chris would these increases apply to my setup (above) or slightly less?

Thanks

 

The dyno on our website performed by a customer was with a standard Comptech setup at 6 psi. With increased pressure, I'd expect the gains with your setup to be the same or greater.
