Hey guys,
Been loving the Z, put in a JWT PopCharger 2 weeks, love the sound it makes and noticed a little difference on the track running 14.0 in the 1/4 mile. I was interested to know what next can do I to my Z to gain a little more horsepower without replacing exhaust? or turbo charging? Anybody please help me or where to send me to find these things along with pricing.

Thanks and have a great day!

 

I think the next thing on the list without replacing the exhaust would be the plenum.

I think the top two are Crawford and Kinetix. Do a search on here for those.

Plenum! if you don't wanna do exhaust...

 

Definately plenum. That would complete the breathing aspect of the motor. At least the air coming in.

 

ok well I had some problems with the search. Can you explain to me what the plenum is please? and what it does? How much they cost and what's the differences? thanks alot!

 

I think it's funny that plenty still tell others to do a search...

Anyway, a very simplified description: the plenum is the intake manifold that brings the air from the intake into the engine.

 

The Crawford & Kinetix allow for more air to enter the engine. The OE plenum has a significant forward slope that prevents good air flow. The a/m plenums are raised at the front. Kinetix is cheaper in price, but made of plastic. Crawford is more expensive and you have to purchase a new strut bar. Both have their pros & cons.

Check out their websites.
