Solar Throttle Body
Has anyone installed a Solar Throttle Body on their C8 LT2 engine? Was there any improvement? I have my C7 unit and just wondering if there is any positives to installing it. The Solar website shows the same TB fitting the LT1 and LT2.

Few YouTubers have done it.
It's on my list of stuff to do; with their throttle controller. Would be nice to see if there were any gains on a dyno versus seat of the pants.
90% sure I'll add some ARH headers while I'm in there too so I may not be the one to have an answer.

Throttle controller is all fake gains; just press the pedal down further.

The throttle controller makes for a more "responsive" throttle. You can dial in less input equals more output. And a load of other combos. I get it's not "HP" gained.

Depends on the size. I tested their smoothed 87mm unit they call a 91mm effective, then an OEM 95mm, then the Soler 95mm smoothed they call a 100mm effective. The 95 and up gave around 5hp paired with ported manifold or 10hp with ptr (both tested).

So was there an increase in the midrange or up top. I thought you are pretty much maxed out with the stock 95mm. Matt upgraded to the 95mm ported to 100 and it appeared to lose a bit on top end in the 1/4 mile with the ported intake. Or did I read this wrong?

Yeah......a friend of mine has that combo but he included the ported intake manifold. At the drag strip, my car can't even get close to his car......it just keeps pulling away His car is strong as heck from the bottom to top end. But it's to figure out which mod is doing the most work. I have 87/91mm Soler Performance myself but I decided to go with ported intake manifold and attck blue filter. Got to get back to the track.

I recently watched a before and after dyno by Eight 16 Garage that compared three added mods. He installed the mods and drove the car around, then to the dyno shop. The before and after mods were performed on the same dyno.
3 mods that were installed together:
1. Halltech Hornet intake manifold.
2. 95mm Soler throttlebody.
3. Lingenfelter pTR carbon intake manifold.
Best baseline dyno with Paragon catback exhaust: 424 Hp and 417 foot pounds of torque.
Best after installing the 3 mods: 437 Hp and 429 foot pounds of torque.
Gains: +13 HP and +12 foot pounds of torque.
The dyno gains started above 4600rpm and steady to redline.
Basically, he really did not feel any difference in power. He said, "maybe a little sluggish at lower rpm and maybe upper rpm pulled a little better" "Or it could be a mind thing". He also stated that he would probably not do these mods again. These are his personal results and his opinions, so I respect that he took the time and expense to share his experience.
Hopefully. the drag strip will tell another story.
Don't shoot the messenger.

Seen a.Z51 with almost the same mods less the Ptr Intake. Around 435 rwhp on the dyno.....same dyno and day bone stock car registered 424 rwhp. The 435 rwhp Z51 went 10.90s at the drag strip. Dyno numbers are good but I refuse to rely on the outcome even if there were high numbers.

I concur - for me I'm interested in just that extra edge in the top end. Stock it seems to run out of breath past 5k. Not really looking for high HP number gains on a chart.
If it allows me to edge out just that much over my friends I'd be happy.

I do controlled condition 60 to 130 mph testing and the difference is extremely minimal. Extremely. We're talking .5 tenths or less.
