Anyone modded their Z06 yet?

Have you looked into the Mamo throttle body? I used Soler on my C7, great item, no issues but I did research the Mamo afterwards i though it may have been a better option.

Soler took note of Brandon's Garage who did flow testing of the MAMO vs the Soler 91mm's which were not a true 91 but a 91 effective. Since then they have just released an improved version of their throttle body that is a billet piece that can be anodized black for better looks and is a true 92mm. The flow rate is 1200CFM which i think if i remember right is a 5% to 6% increase on the effective 91mm's and if i'm not mistaken now just barely edges out the MAMO's.

to answer OP's original thread question i myself will be doing the following bolt on's and no hptuners even though i have the MPIV interface for my other frankenstein build project car but want to keep my extended warranty intact by leaving factory tune alone.

1. Eventuri intake (tried contacting paragon and eventuri if they would ever do an abs opaque cover and/or carbon flash option with bubble shield since i don't care to be flashy on intake either if it saved a grand or so but no dice, no response; and i couldn't live with spending 60% of the cost for sub par gains compared to what eventuri is known for mid range power bumps)
2. 92mm anodized soler performance TB's
3. unobtainium welding gesi 85500 sport cats

Gonna do my own HPtuners logs on 3rd gear pulls noting temperature and humidity conditions and plot this baseline in virtual dyno, then do sport cats and do pulls again and log, then do intake with throttle bodies for final logs. all logs will be done on the same flat road in the same direction.

i'm not a youtube channel or vlog or anything so i just can't justify the time in solely doing TB's versus solely Eventuri intake since likely if you dug into the depths of youtube you could find this done by someone. Its mainly for me and my own verification of how my machine has changed by now doing bolt-ons and just willing to share the results.

i'll likely start my own thread for when i start this adventure since i believe it could be useful to other z06 owners.

Cheers.

Thanks for the info. I contacted Tony Mamo via email but did not get a reply. I guess I will also do soler instead. Looking forward to your build.

The Soler new 92 mm billet looks good.

Interestingly enough I asked Davenport Performance about a throttle body " upgrade " to go with the Corsa Extreme exhaust and cold air intake install and they said they don"t recommend it because their Dyno numbers don"t justify the cost . Which I thought was pretty honest on their part . Have you actually seen testing that showed an increase in HP ? You would think more air , so add more fuel . In this case they suggest not .

All true, but the Corvette tax on the C8 is like no others. Maybe true for LT2, but more gain for the LT6. The C8 is expensive to mod what ever it is.
 
Couldn't speak to any gains for lt2 on its throttle body.

Lt5 gains 15hp at its highest but not sure at what rpm. It's further compounded (not multiplied) when teamed with eventuri of which the combination of the two drop peak torque from 6800rpm to somewhere around 5500rpm?

Sounds reasonable . Regardless , the air/fuel ratio is what counts I believe .
 
Well for those that are doing HFC, jsu stay away from majority of the 200 core type. The consensus is that 400 core is the better choice.

The good news is we have 2 such company that make the 400 cor type hfc for our Z06s.

Atlantic Built - Performance Exhaust Systems (https://atlanticbuilt.ca/)
and

Unobtainium

World-class Titanium, Inconel and Stainless Steel fabrication and more… Our Mission is to be the ultimate performance and sound destination for automotive enthusiasts. We seek to create original and innovative fabricated solutions for the most discerning customers.

The AB ones has the machined crove to use the oem donut type gasket for the driver side.

Spencer at Atlantic Built is a great choice. He’s building me a custom set. Heading to visit him when it stop snowing out here lol
 
My set from unobtainium that I'm installing soon are gesi 85500's.

I don’t doubt that at all. I was just talking to Spencer … he’ll be replying soon. Busy dude in these parts

Yes he did. Took time to explain of his cats. Thanks.

AB also uses the 8550 5" core for those that are looking into doing this. 2 reputable choices and no need to pay brokerage/shipping vs one from the US.

Had an extensive talk with my service guy at the dealer and they are ok with doing bolt on mods as long as i undo the mod if code persists to see if its truly a warranty thing. For the price of the gaskets to put back to stock, no biggie to me if any issue occurs.
