Need some ZL1 modding advice
Hey All,
I'm currently in the parts hording phase of my buid on my ZL1. Thanks to some really great threads here on C5 I've learned a lot and I think I have a decent game plan for my build. My goals at the end of this are to maintain the drive ability that my stock ZL1 currently has as my DD but jack up its racing potential just a bit. I use my car for work daily (30K mile in 18 months) and weekend race with it (think HellCat/GT500 spanking HP). Currently I have been doing lots of AutoX and HPDE days at some local tracks. I've got some drag racing dates planned out as well so you can see I'm after a car that can do it all. Thats why I got a ZL1. Currently have; CAI Apex catch can SS 1-7/8" headers & cat delete Cam Motion Stage 2 camshaft KD Innovation heat exchanger SCT tuner Bo White ported TB ATI Balancer Melling oil pump #10296 RotoFab Supercharger Expansion tank Still planning on; 18% lower pulley = 9.17" lower Balancer bolt - ARP Matching belt tensioner kit H/D timing chain 850 Injectors BAP fuel pump booster Valvespring upgrade BTR Trunion upgrade **dyno tune So what I am asking of my fellow C5 friends is this; 1- if you've done a similar type build is there anything you'd do different? 2- is there anything I'm missing? Not gaskets and obvious stuff. Big items. 3- from your experience is this a smooth easy to use package for driving? 4- is the 18% enough to compensate for the exhaust upgrade? Do more or less? ** what I mean is I know there is a boost drop with the addition of headers Thats all I'm after here and just some advice if anyone has any. I'm certainly not new to Hot Rodding but I'm also not arrogant enough to not accept advice from others who either do these kind of builds or have done them. Not sure who I will get to install the cam as my choices in Vancouver are not as easy as going to someone like Davenport who have a steller reputation. Thanks in advance for your input and I will continue to do my best putting Mustangs and Challengers in their place.

While it may not be nessesary as I am not familiar with your cams specs you likely will want new valve springs. Also I don't see a cold air intake listed.

In addition to valve springs like Redlineviper suggested, you will need a trunion upgrade for your rockers. You will need a balancer bolt. I went with the ARP, so I can re-use it if needed. You will need a catch can as well. And you will need an idler relocation bracket for your 9.17 pulley. Make sure you have a puller to get your factory balancer off and you will need a torque wrench that goes above 200 ftlbs. The ARP bolt gets toqued to 235ftlbs. Your normal 1/2" drive won't go that high.

Just all depends on how much you plan on revving it. In high RPM situations and when using high valve spring pressures, the factory trunion needle bearings may begin walking out of the rocker arm’s trunion bore. Just cheap insurance not to end up with needle bearings all through your engine. They are only $119 from BTR.

I'd consider a new heat exchanger. Ron Davis makes a nice one and it's less $$ than the others. That's what I went with. The stock one is so thin.

Thanks Ted. I'm curious of the power difference between the 18 and 22% pulley. I do DD this car so I do want to make sure I maintain the drivability of the car and I am cautious of making to much of a weekend warrior out of it. On the other items they are already done with the exception of the clutch.

I think you would be better served to go with a custom tune, as a programmer can only do so much. For example, heat is a MAJOR issue with these cars making power, so you want to be sure to turn your coolant pump on early (just after start up), turn your coolant fans on early (about 170 deg) and run a 160 stat. Also- A/F ratios go down the tubes without headers and at LEAST high flow cats or a cat delete. The stock cats go into CAT overtemp which dumps fuel to keep them cool - costing power that you likely cannot adjust for with a handheld. Just a suggestion. dont invest so much, and tune so little.
