Boost control on a centri car

[WIST2019GT]

I was talking with a friend of mine who does alot of fab work and has some pretty fast no prep turbo stuff. I was expressing my jealousy of his ability to control boost on the fly and we came up with some ideas to allow variable boost on a centri car to help get down low/no prep tracks. We came up with a plan to add a wastegate to the intercooler before the MAF and run a stand alone boost controller with a MAC valve to create a "controlled boost leak" to help keep the car from overpowering the road too much.

I know I'm not the first to think of this and I'm aware of the Beefcake torque booster setups, but that is static and doesn't allow for any sort of control. Has anyone here ever tried anything like this or know of any reasons this wouldn't work well or at all? Its all an idea at the moment so poke some holes in this for me.

We have also talked about adding a wheel speed sensor to the front wheels to help correlate data when the car is spinning to open the wastegate and pull power. More ideas that could be explored.

Thanks.

Very very interesting! Im down to see what comes out of this and brain storming of ideas !!

If you talk with engineermike, he says you can handle traction through tuning and it will be much better than doing it through an external boost controller/wastegate.

If you have a good tuner tuning the car, they can control the torque and how it comes on, to where you wouldn't have to do it that way. See what engineermike says here in this thread.

Great concept on that one. I could definitely use this for my DD when I don’t need all 900 whp all the time. But I don’t think its exactly the concept that Wist2019gt is going for.. I could be wrong thou.

I don't disagree but I am not tuning the car myself as I know nothing about tuning and I dont have PBD sending me hundreds of tuning revisions as I make TNT passes on random different nights. This would allow me to control at least a small aspect of power deliver without becoming a tuner or hiring a full time one to test with me.

Yea super easy you tailer torque request or max load however you want it!

Not a new idea. I haven't seen anyone go fast with this setup. Be the first!

Definitely not new. Just trying to make the car a little more consistent in poor track conditions or airport style events where the surfaces is very poor.

many guys add boost controllers to the wastegate setups, no different than a turbo, some run a static pressure all the time, some add a controller.

it's all what you want to do, when adding a controller you are going to want to go down in spring size

S550 with 6r or 10r is less than ideal in poor prep conditions for many reasons. I assume you intend to reduce power to get the car to move, then ramp in or "scramble" more power once hooked. 2nd gear leave on the 10r, lots of data collection (additional sensors and logger) and alot of luck will be needed.

Lots of Dodge guys have been running these systems with PD blowers. I've been using it on my whipple because I have a 150 mm TB with the whole system having big lungs (ported voodoo heads, 2" primaries, etc) and the bypass operation was creating harsh jumps in torque production. The tune has plenty of opportunity to manage load and torque/etc, but the biggest option there is manipulation of the blade angle and that's much more challenging in big power/big TB conditions. Controlling the actual air before the TB manages the anticipated load takes the top off the problem.

Yes this is the plan. I agree that the setup is not ideal for poor conditions and I have considered moving to a new platform of even a TH400 but I figured I could try working with what I have before making drastic changes.

Second gear leave and logging the car at the moment. What additional sensors do you recommend?
