GUYS!! I got a guy here in Frankfort who just supercharged his LS. He's got a Triton Supercharger, and he's poorin about about 340 horses. He showed it to me, but he did not show me the dyno papers. He said 338. I'll get pics soon.

it is good to see these cars finally getting some attention. it is not impossible, just takes some time and money now that we can tune it - which was the showstopper.

I would be interested in how much boost he was running and if he was intercooling some way.
 
I am all over being the other LS owner. Would be the perfect addition to my car and I would bring it anywhere you need it.
 
update:

- I have about 500 miles on it now - everything ok.....

I got the wideband O2 bung installed yesterday, spent some time running the wideband sensor through the dash and console.

I have to travel this week - so next weekend I'll finish up the wideband install (with pics) and then start mapping the air/fuel ratios with my other data - send it to Torrie to refine the tunes as much as possible.

Then schedule a dyno day and Torrie is driving up.
 
Quik, wow, nice job! congrats. what about for us 6cyl guys?
 
It's been a couple of weekends -

I have the wideband installed now.... used my new lift to get to it...


First - the product I am using the LC-1 Lambda Cable - from Innovate MotorSports
http://www.innovatemotorsports.com/products/lc1.php

so the way this works -
- the new wideband O2 sensor into the exhaust bung, the other end into the LC-1.
- the LC-1 then plugs into the analog-in port of the SCT XCalibrator2.
- the SCT XCal plugs into the ODBII port
- the SCT USB port plug into your laptop
- the laptop runs SCT's LiveLink and you can now datalog all the SCT parameters as well as the analog input - which is the LC-1 Air/Fuel measurements....


I then ran the leads form the LC-1 controller into the cabin through the firewall.
Wired it into power and the analog cable that then plugs into the XCal2.

Pic#1: the secert firewall passageway just to the left of the brake pedal pass-through

Pic#2: the plug in the firewall hole - the controller fit through that

Pic#3 - Here's a pic of the exhaust bung (above and to the right of the stock O2 sensor)

Pic#4 - wideband O2 sensor installed

Pic#5 - pic of the O2 sensor wiring tie-wrapped to the fluid lines of the steering box

Pic#6 - a pic of the controller hidden up in the engine bay (under the degas bottle)

Then I programmed the LC-1 to give a 4v constant output - plugged it into the XCal and logged the output - which was 3.988v - so I am loosing 0.012v due to ground-offsets. The LiveLink software allows you adjust the formula behind the scenes to compensate for this offset.



Here is the article I used for my setup: -> http://www.innovatemotorsports.com/forums/showthread.php?t=2671

the user 'Pontisteve' was very knowledgable.
 
So you had to add another O2 sensor just for data logging? Is that going to have to be done if a kit becomes available, or are you just using yours as the test mule and then offer some baseline tunes with a supercharger kit?
 
well - you always have to use a wideband O2 for dyno tuning - most good dyno shops have a wideband attached to their dyno machine - so they can weld in a bung and attach the windband during your session.

Since I am always jacking with my car - and have on-board computer to log many parameters of the car - adding a real a/f reading was all I was missing.

once we are done everything - we will get a feeling how generic we can be with the tune.....
 
Hey Quik,
it looks awesome, but I have a question.
On the top of the sc there is square plenum that turns 90 degrees to feed the pressurized air charge to the intercooler piping. Except for the flange to attach the intercooler tubing to it, it looks just like the plenum on my 3.8 tbird sc motor.
That brings me to my question(s).
did you do anything with the Plenum to remove the very raise flat floor in the bend to the 'cooler tubing?

It was a standard pratice on the sc motor to weld a 1/2 to 1 inch spacer to the bottom the plenum and then machine the opening to as close to round as possible. The limit to the space height was how close to the outside hood skin where you willing to get. this mod would drop the boost a coupe of .1 of a psi, but the flow would increase a lot.

If you have not done this yet are you considering it???

Also was there a particular reason you went with an air-to-air cooler instead of an air to water? (sorry if I missed this in the earlier posts.)

Dang it now I'll just have to score myself a v8 sport and do a manual trans swap on it asap. I'll need so I can be ready when this SC is really in full production.

thanks again Lou you are the man
 
there are a ton of options for the SC t-bird - a bunch of ideas on http://www.sccoa.com/ and http://www.magnumpowers.com/ - but frankly I was hoping to stick with 4 - 5 psi and get everything working.... before looking at higher power level - so I'm staying away from all the things I could do to increase the boost levels for now.

I went air-to-air on the intercooling to stay with a more traditional setup - it turned out to be more of a challenge than I was hoping for.... but it's in now. I need to really stretch it to see if I hurt the flow too much....

more tuning this week - I've been running new tunes almost every day, logging the data and Torrie re-tuning.

should be trying some WOT runs over the weekend.

Any news on this SC install? Pics?
 
great Quik,

I'm a member of SCCOA, but have been off the list for a while. I don't currently have an sc-bird, but my one stang has an sc motor in it.

I did the plenum on the SC and the intermediate shaft pulley. The Pulley was supposed to jack the boost up to 11-12 psi, but with the plenum spacer it only rose to 10 psi. On the other hand, the increased flow made the car and animal and the intercooler input temps only rose about 20 deg.

Good luck with it.
 
sorry - being traveling. I've been daily driving it from over a month now.

We been doing some more tuning. Finally took it from some WOT runs. Felt strong - datalogged it and have a new file to try.

The car is parked and I should be pulling the plugs this weekend to make sure all is good. the A/F is a little tooo safe, so if I can get it back on the road this week We be getting more aggressive with it.

the tip-in and tip-out still needs a little work.
 
$$$$

how much does the supercharger cost that u got quik? also does anyone know howmuch a turbo would cost? exlcuding installation
 
hard questions to answer.....

as this is a proto-type - all the pieces are either fabricated as a one-off or I made them by piecing together several production units (like the coolant hoses).

The only thing 'over-the-counter' is the M90 supercharger, throttle-body and the inlet/outlet plenums. I have purchased two more sets of those items off e-bay - for a couple $100s. I rebuilt them - new snout bearings, snout seal, and coupler. I am currently polishing a unit up to see if I want a shiney unit under the hood...

I probably have several 1000s in materials, one-off pieces and funky tools I have purchased since the start of the project. The goal is to get the kits down to a reasonable piece and let people purchase pieces off e-bay and such if they want.

The fact the you are asking 'how much a turbo would cost without installation' is probably not the right question - it really is not the cost of the parts, but all the fabrication time, test fitting, miscellaneous pieces that you need to create the first one.... and the costs involved in the repeated tuning effort....

As an example - SVC created a one-off supercharger for the LS/T-Bird - the proto-type was selling for $6k but had to be installed by them, you had to live near them and no intercooler. They planned the production kit to be around $10k - but last I heard nothing ever came of it.

I think others are planning on taking another shot at the rear-mount turbo kit - so they can give you a better idea of what they think cost will be like.
 
Whats up with some pics, some stats, videos, ANYTHING. Quik, I know you and I don't get along but I'm still interested in the SC project. You've been saying things are running fine for months now and haven't gotten so much as a pic. Not saying I'm doubting you or your progress, I just don't see the reason in having a working SC on an LS, talking about so much, spending so much money on it, and then not posting any pics or videos. You did a video before but that was at idle and that was like 6 months ago. Whats up with some new footage???? I know I'm not alone on this either. I'm sure we'd all like to see the SCLS do some WOT runs and if you've all ready done them why not video tape them? I know you gotta video recorder. What sense in NOT documenting/recording ur progress and most importantly, your successes! It would be HUGE for the LVC.com website and all its members. I look forward to seeing something, good luck with the rest of your work.
 
I Second That! Pics? Video? Sound Clip? Let Me Test Drive It?:d Update Please..................
 
Well... it's been a while since an update.....

While I was waiting on Geoff for a few things, I decidied to keep my hands busy

with the need to 'up my game' for new pics for Tony - T-MAN for the 2007 LLSOC Calendar (the calendar competition is tough) I though I would solve a couple of items at the same time.

so... i decided to dress up the engine bay and move to a new throttle body.

The setup I am using is a stock T-Bird supercoupe throttle body that perfectly matches the inlet plenum to the SC. The throttle body has not posed a problem yet.... but since it is smaller then the stock LS throttle body - I thought it would be a good target.

so I purchased a Magnum Powers 85MM Throttle Body - the largest aftermarket TB you could buy.

Pics are the TB:
here are the TBs side by side:
