In other words, I like to see Z1 repeat the dyno testing on a different car (engine) with all of the same mods.

This would determine if the results were repeatable, or if your results were just the will of the Z gods.

If they could duplicate the results on a different car, that would indicate that the recipe of mods is very well matched and complemented, i.e. “the perfect set up”.

Johnnydrama has a shot to get you. LOL He is not doing E85 though and it looks like that gained you 10hp.

I will have a repeat of the same mods minus the e85 and injectors, I am staying on 93 octane. It will be installed and tuned by Dynosty in the coming months, don't have a firm date on the calendar yet.

I made 341whp/271wtq with the following list of power or power related mods:

Z1 Intakes
Z1 Plenum Power Mod
Motordyne LTH
Fast Intentions Exhaust
Stillen Lightweight Pulley
Z1 Lightweight Flywheel

The next round will include the following list of upgrades:

Z1 Race Intakes Upgrade (Installed)
Z1 Ported Lower Intake (Installed)
Dewla Dezign Cold Air Intake Guide (Installed)
Z1 2-piece Lightweight Rotors (Installing this weekend)
Jim Wolf C2 Cams (Pending installation and tune at Dynosty)

I was also going to do EPS Big Bore Throttle Bodies but both Z1 and Dynosty have recommended staying away from them due to poor idle quality and reliability issues.

After the tune is done, I will be going back and upgrading the LSD and final drive to 4.08s. At which point my N/A build should be complete... yea right.


I will share with everyone the results of the C2 cams once completed.

How much of a pain was it to install the z1 intake upgrade with the dewla air guide? I was thinking of doing the same, but wasn’t sure there would be room, even with a modified crash bar.

What did Z1 and Dynosty mean by poor idle quality and reliability issues? I've been running the EPS TBs for almost 2 years without any issues and I was remotely tuned by Seb.

Have you considered the slightly oversize TBs provided by Syno? 63mm, maybe not as much of an issue as 70 and still less of a "neck down"

I had not because I wasn’t aware until doing a quick search after your post. Sounds like a more viable path with less risk, more economical as well. Thanks for the recommendation!

My tuner warned me about larger throttle bodies. I ignored him, had Syno (Scott) port and polish my stock TBs out to 63mm, did a bunch of other mods and then got a tune. Not only do they work great, my Z was one of the higher HP NA 370s my Tuner had ever worked on. Even without a tune they didn't cause any idle issues.

I'm actually running the FI tow bar. I'm not entirely sure how they mounted them when it was reassembled at Z1, but Injust had them resting on the bar. The air guide was bolted in at the top. It screws into the bottom of the stock bar, but that's not an option w/ the FI bar. I used a stainless steel zip tie through the hole in the bottom of the guide and the tow hook hole, pulled it as tight as I could and hit it w/ some black spray paint. It was pretty solid that way, but I imagine Z1 screwed it down a little better.
