Thanks for the kind words Rich! I'm glad we could help you build what you wan't. I'll be e-mailing you some comments about the intake manifold. I took some time out last night, and there's a few things I didn't notice on your drawing that we had talked about doing at an earlier date. Just not sure if you still wan't it done or not.

We can machine anything...literally. If you wan't, send me an e-mail (hhtlsp@bellsouth.net) or a PM. Just include a simple sketch/drawing/description of what your wanting to do. I'll send you some pictures of various work we've done, and get you a qoute.

Alex, email sent with all the drawings. I still have to get a drawing of the throttle body flange! I have something trick in the works. Would you be able to throw in a simple throttle body housing as part of the deal? I can have the drawing for it in about a week or two. Any way, i will be stopping back down to visit right before the parts get cut for one last meating to be sure all is good!

DRIVE BY WIRE, HERE WE COME!

The best and most efficient traction control for the ultimate street car! Sounds good but who's going to set it up? MOTEC

Did you know that the 2005 corvette comes with a 90mm Drive By Wire throttle body stock?

I got one for under 300 bucks but i am considering only using the internals since the vette throttle body is cast with a rather large offset from the inlet to the outlet. I would guess it was designed that way for hood clearance issues and i believe it could be inmproved upon. O.C.D. anyone!

TT_Rex_7

I'll see what I can do. I'll need to see the drawing to see whats all involved first.

Did you know that my Hemi Dodge Ram has a Drive By Wire TB? AFAIK, all the Hemi's come with them. (300c, Charger, Ram, etc. etc.)

Edit: http://cgi.ebay.com/ebaymotors/throt...QQcmdZViewItem I can measure the ID on my truck if you'd like.

Those are some nice manifolds. Great work!

My pops has the 2005 corvette. Drive by wire is weird...

Auto Illusions

Yes, please measure it up. I have an 05 vette throttle body. It has a 90mm flap but the opening is some what restrictive as it is only 80mm high and 90mm wide. Sort of an oval to allow the throttle flap to move in the opposite direction to close off the gap and slow down the idle. Really hard to explain unless you had one in your hand to play with!

Is there any real advantage to running drive by wire?

-Destin

The only advantage i could see at all would be in the traction control. In this area the advantage would be huge!

Traction control is normally controlled by cutting timing and fuel. I would say that while making a lot of power under boost with a rotary engine and then cutting fuel and misfiring the ignition is somewhat undesireable.

I am building a street car that will be well capable of spinning the tires off past 3rd gear. The 3-rotor with a single turbo and street port in a light car like the 3rd gen becomes so over powered and undriveable that it can be beat by a car and with much less power in the correct situation!

Traction control is the only chance to drive such a car off the line and actually go fast!

Although it is fun to spin the wheel back and forth trying to keep the car pointing straight and shifting through the gears hoping to find some traction, it is not practical and no matter how good a driver you are, it is uncontrollable and will be slower. At least until you get into 4th gear!

Imagine pushing on the accelorator and the computer quickly decides how much power can be laid down and then lays it down, right up until the breaking point all before you could have even thought about reacting! Some might say it will take away from the drivers feedback but remember, it can easily be turned off by a flick of a switch!

Although it will take a lot of setting up, it has the potential to eventually become an unfair advantage.

The Motec will control a drive by wire system but has not released the new software which will include traction control via limiting throttle position using the drive by wire setup! I am hoping it will be released before the car is put on the road. Seeing how the build schedule is so far off of schedule, this may not be a problem! Any way, i would only be waiting for a software upgrade which will not need a complete re-install. I could get the car running with the current software and upgrade the software later without any physical changes except for some extra hours tuning!

I am saving up my pennies right now, hopefully i can get the Motec system by the middle of next month without re-financing anything!

For his application, yes. Since he's going from the stock dual stage TB, to a custom single TB, air will enter both the primary and secondary ports at partial throttle. With the stock dual stage TB, air only enters the primary ports at partial throttle.

I have a post at the end of this thread that will help explain it: https://www.rx7club.com/single-turbo-rx-7s-23/porting-uim-single-plane-manifold-448379/

With a "drive-by-wire" TB, you can adjust it so that at lower RPMs/Idle, he can go WOT, but have it programmed so that the TB only partially opens. By doing this, it'll only allow a certain amount of air in at once, and gradually allow more in (TB opens up more) as the RPMs rise. This is so that to much air doesn't enter the motor, causing it to bog. Here's some good details about drive-by-wire TB's. They are speaking about one from a BMW, but they all work the same.

Edit: Well, Rich beat me to an explanation. He's apparently using it for a traction control, not issues with bogging the car.

TT_Rex_7

I'll double check first thing tomorrow, but I think it was ~80-85mm last time I had the intake off.

However, there's quite a few luxury cars that have this system. (BMW, Lexus, etc. etc.) You should try searching around to see if you find one that's 90-95mm. I know BBK makes custom drive by wire TB's.

That actually makes a lot of sense! If the Motec software can handle this type of programming of the throttle control, i would have 2 excellent reasons to want the drive by wire setup as larger single throttle bodies are somewhat less desireable for street use!

TT_Rex_7

I wish the Microtech would control a drive-by-wire TB. Maybe the LT16 will, but who knows when that damn thing will come out. My luck, i'd be one of the first to get it, and it'd have all sorts of newly released issues!

If I have issues with bogging with an 80mm TB, i'll probably machine a custom dual stage TB, and hope it gets rid of the problem.

-Alex

Edit: BTW, who did you speak with at Innovative?! I tried e-mailing sales ~ a week ago, and still no responce.

I was quoted around $6500 for an M800 with advanced features unlocked and the harness. The M600 was only slightly less after loading it up with enough logging memory to actually be useful, and the advanced features unlock. Is that consistent with the prices you've seen?

Auto Illusions

m820 adv tune ecu $5549.61
m800 basic harness $625.00
m800 termination kit $105.00
6 cyl injector term kit $20.51
This is the basic ecu with traction control turned on and the necessary wires and terminals. Must add sensors!

The charge for activating the drive by wire is $250 but it will not control the traction control via the throttle control with the current software!

I also included 2 4-channel cdi ignition boxes and coils along with a mini dash display and a few unnecesary sensors which all totaled over $12000 and i still have to add an expansion box since the drive by wire will suck up a few channels i can not spare!

Of course that was reatil prices from Motec. I would like to find someone willing to work with me on the price to help ease the pain as it would be a bit to difficutl to become a motec dealer at this time.

I might be able to help....

When you are ordering that much all at once, I would hope someone would be willing to cut you some kind of deal.

TT_Rex_7

The Dodge Ram Hemi TB is 80mm. The 6.1L Hemi might have a larger TB, but i'm not sure.

BTW Rich, who did you speak with at innovative?

Ask for justin! Remember i can get you the turbo at a good price as an innovative dealer!

Awsome project. Any new updates??

Auto Illusions

Sorry but nothing interesting finished at this point. I am extremely busy keeping the shop going so not a lot of time to work on the car.

I do have a sweeeeeet billet aluminum intake manifold in the works by TT Rex 7. It should cost about as much as i make in a year but will it will be unique, I can guarantee that!
Don't worry, I will not be shy on the picutes as soon as it is finished. Hopefully it works as well as it will look as the entire intake design was done by me!

My GSXR has a second set of butterflys that are controled electronically, the only reason why there even ridable with 178 at the crank.

I know it has been a while but i have been working on the project hard and will continue this time for at leat a couple months.

I ordered custom radiator and electric pump from mezeir.

I have since finished the entire turbo system and exhaust and also installed my new PWR 4" barrel style water to air intercooler. I have to get the bumper fitted before i can order the front mount heat exchanger and oil coolers but the radiator will be here in 3-4 weeks!

I completeted the installation of the fuel line, return line, gas tank breather filter, aeromotive y-block 2way splitter and the aeromotive pressure regulator! All left to do there is make an aluminum shield for under the car and run the 8an lines to and from the fuel rails however i have to wait for the intake to be finished for that part.

I have also gotten all new injector and decided to run 3-850cc primaries in stock location and 6 secondaries (1 per each intake runner) 3-160lb and 3-321lb which will be run parallel as pairs.

I have decided to keep it all as well so i still have some fabing to go.
Power steering, airconditioning, heat, water to air, huge turbo, along with a huge custom intake manifold with 4" piping all over!

There is absolutely no room in the engine compartment but it all fits under the stock hood, even though i am not running it!

Sorry but no pictures for now, i would rather spend more time working on the car for now and will post a few photos when the intake manifold is completed and on.


Hurry up alex! I am waiting!

Just kidding, take your time, i want the inatke to be the center piece and it has to be perfect.

Were are the pictures of your intake?
