Default Corvette C7 ported throttle body

Whats the best corvette c7 ported throttle body and what size and do you feel the difference and throttle response and how many horsepower does it increase and do you need to tune it again

No gains. Trust me. Maybe a tiny bit more throttle response. Callaway donít believe in them on their builds,thatís enough for me.I have one. Sounds like from your other post your really hung up on this thing to be faster. Ainít gonna do much with a couple grand. Sorry it is what it is.

Hamad, if you are looking for a better/faster response, we can say w/ confidence that ours outperforms the competition. We do not target adding power, our goal is to redistribute it. That is, deliver it earlier in the throttle travel. It truly feels like you've added power but the truth is it doesn't, at least not significantly or measurable in an accurate consistent manner. Our C7's are calibrated by the factory in away that feel under-powered at part throttle, but they are not under-powered at all, it is just a matter of when and how power is delivered.

Be careful of products promising power gains at wide open throttle (WOT). In any case, our product also includes features that if the added power at WOT exist as claimed by others, you will also have it and more of it, by the way. Please give us a visit.

You do not need tuning w/ our product. Ours is the 87 mm bore, for the Stingray, Z51, GS, and Z06. 2014-present. What's your C7?

I can honestly say the Soler Perfomance TB is a definite improvement. The more you drive it the more you realize what a difference it makes.

I'm testing Mike's throttle body right now and it is awesome. The Soler Engineering throttle body is more than just porting, and improves the throttle response tremendously, even when compared to other ported throttle bodies.

I bought a Tony Mamo PTB. Didn't feel any difference at all. The only difference I felt is when I had the driver demand tables tuned.

My experience was quite the opposite. I bought a Mamo PTB and it fixed everything I didn't like about the throttle pedal in this car. I was quite happy with it.

Then I saw the thread about C7 throttle response started by Mike from Soler Engineering. I was intrigued and figured it couldn't hurt to try one of these throttle bodies, especially since he guaranteed an improvement and if I didn't like it, I could send it back and he would get me another Mamo PTB. Well, I'm quite happy to say that the throttle response in my car is dramatically improved over the Mamo PTB at partial throttle. It's like a completely different car.

Actually, I've been thinking about this very thing; I mean, I only drove my car for three days so far: A 700 mile trip from point of purchase home. But, I'm used to a gen-1 small block chevy that makes 400 rwhp. The C7 makes gobs more torque, but it's not nearly as playful off-throttle on my minirammed 385. Tip-in doesn't hardly do anything. The SBC has instant gratification when you tap the gas. My newly purchased '14 C7, tossing a few revs seems to require patience, and then it takes a few seconds to climb down off the RPMs. Around-town, it feels almost truck-like in traffic. I was hoping for more low throttle torque that I *know* is in there. My Firebird shouldn't feel snappier, especially when I know there's at least a hundred ft.lb less torque below 3500 RPM.

I want the transient throttle response to be sort of like this (just with less cam, of course):

Did you find that the modified throttle body helped increase off-throttle response for around-town driving? What about the transient tip-in, when you crack the throttle, then shut it rapidly? I suspect that one is solved via the mechanical modification whereas the second might require a tuner...

Some of the throttle muddiness in these cars is definitely in the tune. There's a significant delay when you snap the throttle open like that on a C7. So much so that you can quickly put the pedal to the floor and back off without having the engine rev beyond 1800 rpm. Slam the pedal down and back up twice in a row and it might hit 2400 rpm with the stock throttle body. If I do that now, it runs up against the 4000 rpm free-rev limiter.

Thinking about getting a SBC TB for the CCA Corvette...

A ported throttle body itself will not be much of a gain on an otherwise stock setup. Pray Performance has gained dyno proven 16rwhp with their ported oem Intake manifold/Throttle body combo. They have also swapped to a ported 95mm LT5 throttle body while strapped to the dyno and gained another almost 10rwhp over the stock ported 87mm TB. The point of a ported TB is to work as a system with a ported intake manifold/headers etc. As much flow in and as much flow out is the goal.

The thing that can be presented as FACT is that his customers back up the numbers at the TRACK.. where gain quantification matters. He also has MANY dyno tests and plenty of actual DATA to prove his gains on his FB page Pray Performance. I am not meaning this to sound like a plug, but as a Pray Performance customer, who has witnessed personally what the combos do through my vehicle and others vehicles time after time.. I am convinced.

With this said, if you plan on going with a typical "full bolton" NA All motor setup which typically is
Ported IM/TB,
CAI(Halltech etc),
Headers/xpipe(I run 2" ARH into 3" catted xpipe),
Flex fuel sensor for E85,
Pray Performance PCM/TCM tFlex fuel tuning on an A8 car
Drag pack(My GS uses 18x5 fronts and 18x12 rear wheels with MT ET Street 305/35-18 drag radials)

This combo if a proven, repeatable 10 second 1/4 mile combo on an A8 car. I have run numerous 10 second passes in my NA Grand Sport. Pray has MULTIPLE 6gen Camaros in the mid 10second area with a simple combo and his magic hands on tuning.
