- Manual Boost Controller - Hobbs Switch - Electronic Boost Controller - Choose the appropriate wastegate actuator spring rating for something higher |
i know what im buying this is a great idea..so basically you have to hook a vacuum line to the actuator on the exhaust then itll open at 10psi right? Also im guessing your gonna need to cut your downpipe/exhaust to weld this in?

This is a really sweet product.
|
You could always put a toggle in for on and of use.
|
or maybe not.Didn't look at it good the first time.
|
Yeah.... no toggle switch. Guys! This is epic. I personally would drive a stock exhaust for the ultimate sleeper look and then when I punch it, this thing would be a monster!!

|

Was the exhaust on the supra pinched closed? I mean c'mon, 50whp with the cutout open. Real world results for us would be in the 5whp range. 10whp on a stock exhaust car maybe.

Will a lower displacement motor such as the Cobalt reach 55whp gains on a stock turbo? Absolutely not and nor did I infer you would. I merely gave an example as to this part allowing for more power to happen along with the unregistered statistics such as turbo response and transition time between shifts that can not be measured. Remember, NASCAR says it best and it's true, "the best exhaust....is no exhaust at all." And this holds true in N/A and especially turbo. |
Always so defensive, he was just asking a question haha

My apologies if it comes off that way but text does not transfer emotion well. But there's nothing defensive about it. I like facts over "hear say." And he didn't ask a question, he made a speculative inquisition as to the supra not really making that much power in real world and thus this would be mean a cobalt will only make 5whp more. I don't follow speculation or gossip. I follow the facts on hand and its data. The data and dyno time shows directly that that boost cut-out WILL make more power and there was nothing fake about the 50whp+ more on the Supra. Also because I was there when they did the video considering it was filmed by a very good friend.

It was a question hence the "?". But anyways I just dont want someone buying this expecting big numbers and getting let down. Best thing to do is have someone be your test mule and get a dyno number for opened and closed runs.

Ill be getting me one later down the road. This product is genius. Might even set it up in my modular section in my downpipe for easy in and out.
