This is more about transferring power to early throttle application. We've also added every detail needed to perform at WOT as well. The greater differences show up at part throttle.

Thanks,

OK

Anyways... The Soler unit is superb! I'll write an in-depth review once I have a bit more time but there is an immediate difference in feel/performance that completely surprised me (just.. WOW). I'm very happy with the customer service, craftsmanship, attention to detail, and overall reassurance of the product/company.

Glad to see Mike here on the forum! Great to have them here , I had originally started another thread asking about this throttle body so I'll update both with a more "formal" review soon.

BUT,

I'll leave you guys with this: This product is well worth the money and it is a substantial improvement! Couldn't be happier!

Any difference in wide open throttle on a hot day?

If you don't have a ported throttle body on your car right now, I can tell you with 100% certainty, you will notice a significant difference in the feel of the car when you step on the gas. I remember before I had this SS I had a 16 V6, when I went from stock to CAI + Ported throttle body, the difference when I hit the gas was night and day. I don't see this being any different. All of our cars stock have a delay, it's just unfortunately a characteristic of the car.

Give it until after the weekend if you can, and I'm sure other members and myself will provide reviews. Only other thing I have on my car ATM is a CAI, so we shall see the difference.

Did a lot of reading about these over on CorvetteForum. Just submitted my order. Looking forward to the results and posting them here!

Absolutely, everyone in this business has had them. The good thing is that we have 12ea pre-sales test samples running out there, and we've weeded codes and other issues out.

We aim for the highest possible airflow for the stock calibration, and if we ever were to cross the line and you get a code, we'll send you a custom made TB to match your calibration. This is rare, but it does happen. I wish I could give you an absolute "NO" to your question, but I'd be lying.

Looks like a quality product. However I choose to go with Tony Mamo.
His experience and knowledge of these throttle bodies are second to none.
Sure yours are fine as well.

Looks interesting and I'm looking forward to the feedback, I'm using a Tony Mamo with a throttle controller on an M6 2SS 1LE and it transformed the car as far as drivability, no more stalling, and lurching takeoffs. I've been driving manual transmissions for 40+ years and after 4K miles in this car I threw in the towel, it wasn't me that was the problem. For you guys trying these out, keep in mind it will take 100-300 miles and several start cycles before your going to realize any benefits as the cars ECM needs to learn it.

Great to see another trickle down of tech from the C7 to the Camaro.

First the MightyMouse Catch Can.. Now the Soler Performance Premium Modified, Ported, and Calibrated Throttle Body...

Ordering this product was a no brainer.
I'm looking forward to changing my life in 15 minutes or less.

Looks like Solar is cutting away more metal than Mamo for more flow.

There is a much debated problem w/ the throttle response of the LT1/LT4 engines, manual or auto, the issue has been described in this and other forums (Corvette, Camaro, CTS-V, Trucks, SUV’s), just to mention a few descriptions:

- Throttle Lag
- Delayed response
- Car feeling heavy or not nimble
- Difficulty climbing hills at low/moderate throttle
- Uncertainty when passing other cars or unpredictable response at low/moderate throttle
- Stumble when shifting on manual transmissions

You name it, this has been my issue w/ my Corvette 7 since test driving at the dealership. I've tried a Throttle controller, AFM disabler, ECM Tuning, and arguably the three most talked about ported throttle bodies (PTB) out there. I have also combined some of the above w/ some success but still not enough. One just needs to hop into almost any other comparable car to feel they respond better.

After spending so much time/money, I decided to take it upon myself to find out, I also have all the equipment needed at work (measuring, testing, simulating, machining etc.)

Long story short; it is the throttle body. Between idle (~5 degree throttle) to ~30 deg throttle angle the amount of mass air flow (which is proportional to power) puts our cars at a weigh to power ratio similar to that of trucks and SUV’s, both in terms of absolute value and rate of change. Not to be confused w/ the weight to power ratio that is usually published, which is calculated at WOT, above 35 deg throttle angle our engines shine. It is on the part throttle range (idle to 30 deg) that the issue exists.

I’m not going to speculate on the reasons, but I can tell you that our throttle body p/n 12678223 or 12620263 is used in many GM vehicles and that such throttle response helps w/ fuel economy. That helps to keep parts cost low and meet EPA requirements for the fleet. However, I do not think one size fits all and that a high performance car needs to sacrifice performance for economy.

The throttle controller and the tune improve response by making the throttle plate move faster between the 5-30 deg range. Faster, but it still needs to go through a tortuous path for the air flow, and the manifold pressure doesn’t recover as fast. It is a transient process, and it is from the intake manifold where the pistons suck the air from. Notice that this is not true throttle response, it is just tricking the ECM into thinking you have pushed the accelerator pedal harder. The actual throttle response is the same, only physical changes to the throttle can make for a true throttle response.

The existing aftermarket ported throttle bodies also helped, they do change the throttle physically, but their effect only starts to take place at about 25 deg in what I thought was the best one of them. Definitely a step in the right direction, but I noticed they were not optimized and that more could be extracted from them, that is a throttle body that can increase the absolute value and rate of change of mass air flow right from idle and up to 35 degrees to achieve the same weight to power ratio (in that range) of similar high performance cars that feel nimble and fun to drive at part throttle.

Another long story short, I reversed engineered 10ea OEM throttle bodies, 3ea aftermarket ported throttle bodies, and a benchmark (competing car maker model) OEM throttle body. Optimized/modified the OEM throttle body to meet the benchmark throttle response as well as the goal stated above.

Our modified throttle bodies (MTB) are made (CNC machined) from a brand new OEM throttle body, flow and engine tested. Our design has been fully vetted by Corvette 7, Camaro 6, CTS-V owners, fully and openly tested by Corvette Forum members mainly. Driven in different conditions/modes for a few thousands of miles now at extreme temperatures and altitudes.

See pics below for more insight into what I’m talking about…and most importantly what do you think? All comments welcome.

What do the cut out notches in throat of body do exactly?

The Mamo TB gives a slight improvement over the OE TB. The Soler is on a whole different level, and much better bang for the buck. I swapped my Mamo TB on my C7 Z06 for one of Mike's TB and never looked back. Not really even a comparison......the Soler is much better TB without any doubt. I liked it so much, I put one on my 2018 ZL1 with under 300 miles on it. It really is THAT good!!

Placebo effect. Highly doubtful.
Then again you can train your mind to believe anything. Just got to believe.

No placebo here, we provide hard numbers. Anyone with a simple data streaming tool can measure it.

When you went from stock TB to a PTB; did you feel a difference? Was that the placebo effect too? In any case; how do you know?

Just because your the new guy on the block and people want to drink your kool aid doesn't mean I'm going to partake.
Especially when guys are putting you up against a guy that has the knowledge and experience to back it up.
Rather me answer your questions how about you answer mine?
Supply some real fact and or data that yours out performs Tony's.
Until then when some guy quotes me saying how much better yours is over Tony's with no real evidence or actual proof I'm going to reference the Placebo effect.
Not saying your TB is crap or not good. Just not saying its anything. You haven't showed anything but throw around a few fancy words.
