What Size Throttle Body?
 

I have a stock motor with a Paxton NOVI 2000. I have equal length Bassani headers with matching X-Pipe and 2 chamber Flowmasters. I am going to upgrade intake and heads later on, but I am working on a custom tube that goes from the supercharger to the TB. Before I can start this though I need to know what size TB and EGR spacer to buy. Is 80mm to big? I'm not going too radical with the motor, just want to be in the 11's or so. I need some suggestions so I can purchase the TB and EGR apacer first so I know what diameter of tubing to use from the Supercharger. Thanks

I would go with a 70mm TB with the Novi2000. I do think 80mm would be too big.

Later,

i 2nd the 70mm tb recommendation

Thanks for the info, Should I get a 70mm mass air as well?



Bobby

A 70 mm TB should work well. As for the mass-air, I would recommend a Pro-M 75 mm + - are you using a blow-through type? Pro-M has a new meter out, the Univer. You can get these in the blow-thru design in many sizes. Very nice units that meter very well from what I hear.

What do you mean blow through? My mass air meter is installed before the supercharger. Is this blow through design a new thing or does it allow the mass air meter to be installed somewhere else? Thanks
