Hi, I'm a novice in sport car tech (or cars for that matter) and have been stumbling lately on some discussions about "ported throttle body".
Just wondering why GM engineers have not taken action on improving the throttle body just as done by aftermarket.
Maybe they experts must have reasons behind it. Any one please share some info.

Thanks,

Vet on!

 

Vehicle manufacturer must accommodate many divergent interests into a single design. Immovable obstacles include emissions, fuel economy and safety standards, High on the priority list are driveability, longevity and design/manufacturing cost. Performance is a variable factor in which manufacturer has some latitude in design.

Aftermarket does not have to meet such stringent criteria and can therefore slant towards more performance with less regard to other factors. As performance increases, compromise in above factors also increases. In the case of the throttle body, once the design gets the green light it is difficult to change, especially if it requires a different casting. If the problem is recognized by manufacturer, preferred course correction would be to issue updated calibration.

 

Look at the Soler Performance web site. There is some great info that will answer most of your questions. https://www.solerengineering.com/

I just got my solar tb and tc delivered ....mike couldn’t be better and the parts look incredibly well produced.


Cant wait to put on very soon!

 

Actually, the original TB works just fine, thank you. Btw, Callaway does not use ported TBs, either. DRIVE and enjoy!!!

 

The C7 throttle body is the same one used in many other GM vehicles, including trucks. Cost is probably the main reason but I also suspect GM wanted to error on the side of safety and keep the throttle response a little less aggressive or responsive.

For the best throttle response a throttle controller is a must.

 

^^^^^^ This ^^^^^^^^^

Just curious, have you guys specifically tried the Soler throttle body and any brand controller (preferably the Soler) on a M/T C7?

 

Putting mine on in about an hour!!! I’ll report back on the changes and progress

 

If you disconnect the battery, roll the windows down a little bit first. So you can open and close the doors without the windows hitting the top.

 

Exactly guys gives opinions on things that they not even tried. If they had ever driven a Soler Engineering TB and the TB controller by Soler they would change their mind.

 

I love the snarky responses from some of the experts here

So for those that know me also know I dont comment just to give some BULLS×+×T answers like some do......

As a matter of fact yes I have Vitesse throttle controller and like all throttle controllers , Vitesse , Pedal Commander, Sprint and Solar they do serve a purpose and I do like them .

Being able to tailor the throttle response to what I like is important to me . Especially at the track ... yes unlike most folks I do drive my car , work on it myself and actually take it to the track and race it

I think every one of the throttle controllers EXCEPT Solar is over priced !!!!!
The Solar Throttle controller is the best bang for the buck and should be the first MOD anybody should do !!!!

My comment above was directed more towards the throttle body and the value of a ported throttle body on a stock unmodified LT 1 or LT5 .

Again, I do have an. EDGYVETTE ported throttle body so ....
Can you modify the off idle characteristics of the throttle body... sure

Will it produce any more power ...absolutely none on a stock motor !
And I challenge anyone who has a ported throttle body ,on a stock motor, no matter what the brand to show me the data that shows a power gain ...

You want a cheap power gain , spend the money on a EDGYVETTE ported intake manifold , I have a fist full of time tickets to prove the gain from this mod
Just my two cents
Dave

 

Update....tc and tb installed and wow....what a difference...just so much more responsive and don’t have to work the pedal to get power.

4 drives today and I have to be careful not to push it too much....what a great addition, very different feel to the car...:can’t wait to wake up at 5 to drive to the gym...

what a great mod, who would have thought you could change the driving experience that much for this cheap.


and Mike was awesome as were the gentlemen that helped me install...great mod, great service and met some greet guys from the club

 

Hi, Dave. Thanks for your kind words. I bet you are talking about WOT. If so, you are pretty much on point.

But, WOT is only one throttle position, and the engine is producing power at all throttle positions; ramping off, driveability, smoothness, predictability, etc., come from more power at those throttle positions. We happen to be working right now on a long overdue comprehensive data collection effort that we'll publish here; including simulations, airflow bench test, and load dyno test to put numbers and shape these adjectives. Preliminary results are showing power, and lots of it percentage-wise, at partial throttle. It can also be demonstrated that once you widen and "clean-up" the airflow path, when the TB becomes the restriction, that power in moderate amounts can be achieved at WOT as well.

 

You are very welcome, Jipper. Glad to hear you liked it. We think over here that our cars have right ingredients already, it is just a matter of having it how and when we want it, then it feels like a different car!

...and like you said, it doesn't cost much and takes very little work.

 

I’ve only been to the drag strip about six days for fun in cars and as I remember throttle response and control didn’t seem very critical.

But I’ve spent more days than I can count riding 1000 cc bikes on road race courses such as Willow Springs, Spring Mountain, Fontana, Chuckawalla Valley and Button Willow not racing but at trackdays in the expert/race group where throttle control was extremely critical.

Yes, I agree a ported throttle body and a throttle controller doesn’t make any more horse powder or torque but it makes the available power more useable, controllable and available faster.

Simple put they greatly improved my connection to the car’s power.

 

The Soler TB changed my C7 Z06.. night and day compared to the OEM unit.. but the pure linear control is well worth it, just amazing difference. The OEM TB lag was horrible for me.. hated it.

 

funny thing with the lag is I knew it was there just not how bad it was....

to the guys out there saying no need, you might be right for your driving style; however, I would strongly encourage you to check out a similar model with it installed and see if you like it.


i could not have anticipated how big a difference it would make personally

 

^^^^^^ This.

Transformed my C7 Z06 M7 as well.

 

....particularly in regards to an otherwise stock LT1/M7 combo.
