JWT and Z-Tube figures
 

Hey All,
Can someone please let me know what the reasonable RWHP is with a JWT Popcharger and Z-Tube installed? Also further down the line I'll be replacing these items with a SC, so I would like to know with that in mind, what type of exhaust would one recommend?

Thanks!

Go that way, really fast. If something gets in your way, turn.

Good catch SixFive. Most people don't get it. I guess that's a sign of either our age or good taste in movies.

Our central florida dyno day results showed Ztube/Popcharger combo to have a solid 7rwhp and 7torque gain on 5ATs and about 5rwhp and 5torque gain on 6MTs. These are both all the way through the curve, not just peak.

Well since I have the data from the CF Dyno Day in front of me might as well re-post the info... the AVERAGE GAINS across the board seem to be a little lower than what dabomb sited...

5AT stock / redline = 227.6rwhp & 216.7 rwtq
5AT Z-Tube, P/C / redline = 231.6rwhp & 220.5rwtq

6MT stock / redline = 229.7rwhp & 222.6rwtq
6MT Z-Tube, P/C / redline = 229.2rwhp & 226.7rwtq

If I remember right the average gains across the rpm range were about 5rwhp and about 5 ft-lb rwtq.

FYI, this is the mod to do for sound, not performance.

301-bhp!!! ...and growing!

Thanks Neff, i was too lazy to go get the actual values.

I remember that the peak comparison is misleading as through the curve the gain is a couple more (especially on 6MT) but yes this is a sound mod unless u have a aftermarket plenum that can take advantage of the added airflow....search for "Central Florida Dyno Day Results" and read Neff's great writeup and spreadsheet of the results.

Re: JWT and Z-Tube figures
 

Now would you say that the 4rwtq is gained by the z-tube or the pop charger? I'm still debating between the jw pop charger and a k&n drop in filter. Then one day I will wake up and say I want an Injen, so indecisive. Does the bumper have to be completely removed to install the Injen?

Re: JWT and Z-Tube figures
 

Read the dyno day info and you'll know the answer to this question. People dynoed with the z-tube and P/C, the Z-Tube and P/C with no heat shield, the Z-Tube and stock air box, etc...

301-bhp!!! ...and growing!

not enough hp/tq gains to tell and difference... intakes are MOSTLY for sound... and slightly better mpg

as for exhaust for n/a you will need a 2.5 inch but if you plan on FI go with 3 inch

Fast Intentions is a very good exhaust... search it...

Talk about an OLD thread. :thewave:

Damn i didn’t realize lol... i guess i have two pointless post

LOL Way to work on the post count Beebo! 2004? Really?
