victory_red_SS update: sending back the turbo's
thats what I was thinking too man. budget is hurting right now though... putting most my paycheck away each week to buy a house next year so that is priority #1. But hopefully my side business starts pickin up some more, plus my 1/4 bonuses at work help too. Who made your bellhousing adapter for the T-56.. cause I could probably get my hands on one cheap. plus I have a few old rears lying around... plus my friend owns a metal shop... I might just be RWD #2 man.

Update update, reading required
this thing is gonna be sick but with 2 huge turbos on there how is the thing gonna spool upi mean when it hit its gonna be like a f&*%in runnaway frieght train going down hill. but i feel like it will take so long to spool that it wont be worth it. but either way this car is gonna be awsome

Whats it do?
Main Function
The TTS Controllers' main function is to solve the problem of displacement and turbo lag. The 2.0L LSJ can't drive two turbos in parallel and one enourmous turbo will lag for daily driving. Therefore we must find a way to halt the the flow of exhaust gases to drive the primary turbo, then the secondary turbo.
Other functions
The TTS has been engineered in order to function as a signal generator and controller for other vital functions. It's also engineered as a theft device that will not allow the vehicle to be started without a system code. Necessary precautions have been taken to allow manual subsystems to override the TTS' ability to control certain systems. (ie: Fuel Pump, Boost Control, etc..) However, in the event of a failure of any of the control system, the TTS will "politely" indicate an issue with a gentle alarm and yellow warning indicator. If the failure is detrimental to operation and safety, the TTS will disable the vehicle until the problem is fixed. Safety first.
The TTS will allow us a greater range of control over how the turbos operates. It can even take into consideration the wear and tear of a turbo and accommodate for change. Driven by the Honeywell military pressure transducer, and implementing a complex algorithm to reduce the need of a second transducer, the TTS will solve a lot of problems posed by twin-turboing a 4 cylinder.
It's a truly novel idea. One that may be impossible to mimic by others who wish to twin-turbo a small displacement engine.

That will change from "might" to "will be" and then to "am" before to long. I don't need to be the only one.

I hear ya man. gotta send me a list of parts so I can start shopping. I'm taking the nitrous out of my lincoln tomorrow so I don't blow up my daily driver before the balt is done. lol
what did u pay for your honeywell transducer im kinda curious cuz thats up my alley of work, im soon to be an instrument technician, you have no idea how many twin turbo compressors that ive put psv's on as a waste gate instead its fun,
i would have went a couple different ways on the transducer as there is better for cheaper, but thats the trick of the trade, do u know what psv's they are using, and what there going to set for

I'm thinking about going RWD eventually, if I went RWD, I would transplant the motor to the back. No extra weight (tranny, driveshaft, rear end ect), no fabbing up adaptors, or having to change the mounting style of the motor. If I did all or most of the work it would be A LOT cheaper than leaving the motor in the front. Also it would have more weight over the rear wheels for better traction.
well that honeywell u def got hit with a good markup lol, i wont lie on that one, but normally psv's are set for a certain pop off pressure, u can get electronic psv's but they are well yah very pricy lol, i could see the transducer being used as way to open a valve at certain pressure, cuz its kinda what its meant for, but yah a normal psv ran by air is set for a certain pop off pressure, so once it hits a certain pressure it relieves presure,
but it sounds like and looks like how i set up a recent pressure truck, except i used a honeywell pressure transmitter and programmed in my program to open a valve at 1500 psi so the ******* wouldnt blow the piping up, looking at the screen that JBP set-up that your using actuators to open up. thus using a transducer, shall be interesting set-up to see, i need pitures for sure

Wow. That is insane. I can't wait till you get it done. Glad to see that you are going sequential. Last I understood you were putting them parallel which didn't make sense to me, but sequential does.

This is a little off subject...but I test drove the new Si today. I cannot get over how good the transmission feels and how solid the engine runs. It is the smoothest 6 speed I have ever driven. Aside from the feel, the car doesn't go and styling inside and out is awful. What a waste...

This is true. However, even more expensive cars it's hard to find that median. For instance, in my C5...it's brutal power but sloppy transmission. The engine doesn't feel anywhere near as solid as the Si did. Maybe Porsche has the answer...

new 335i = the sex. Drives real nicely, is damn fast for the price, and has tons of potential for modding. wait til the new m3 comes out and that thing will drop even more in price. Spend mid 30's on a car that rides like a bimmer, but goes like a raped ape. with a tune i guaruntee that thing hits mid 12's.

I'm not a BMW fan for many reasons...most of which are associated with the brand name rather than the car itself. For a true sports car, I wouldn't own a BMW - Corvette all the WAY.

Watch the muscle of that supercharged C6 go. If you think it's loud wait till he hits the throttle at 1:01. Nothing screams sports car like that one does...

You weren't around for the original thread where I state that I am going hunting for the big V's............................... Vettes and Vipers.
We are going for 750RWHP

It isn't as simple as that because in that cost I am having a complete chassis built and the back end tubbed. I am also modifying many things to fit the T56 tranny and put in the 4-link suspension. With out doing these parts of the conversion, it would be considerably cheaper.
For people just wanting to be a Cobalt version of a Sky/Soltice the cost could likely be much more palatable.

Your injectors work by the way. thanks. just causing problems for me though.
