| We are looking at 60 - 75 HP from the 30 lb and an additional 10 - 20 from the stock injectors. |
|
My main question is can the average DIY'er do it himself? I know that the work Lou put into the SC was enormous! Also, what type of technical support will Geoff provide for these kits?
|
|
Then just drill and tap a hole on the intake and add another injector! Yup, turbo dodge guys have been doing this for years, and it works well, too.
|
I really wasn't aware that this had been in the works for so long. Is there a "programming pcm's for dummies" at the local wal-mart?

As you know we use the XCal or Livewire to upload tunes into our LSes. www.sctflash.com. Tuners sell their services by creating new 'tuned' PCM codes for your LS and you upload it via the unit.
There is also a Pro Racer package that is the same software the tuning companies use - but limited to a single vehicle. So it allows you all the control over the car - via the PCM software. There is some good coarse that you can take - http://www.calibratedsuccess.com/ where is teaches the tuning and talks about the SCT software specifically. He also has a book that is a 'starter' type book -> http://www.cartechbooks.com/vstore/w...6&WebPage_ID=4 |

I didn't see any confirmation of it working for the V8? Is there going to be a kit for the V8? And does this mean that we can get 350+ HP without having to use NOS?

Saab came out with a "ping detector" on the 16V 900 turbos. I've seen other vehicles retrofitted with this. I believe it somehow gets rid of boost when knock is sensed (not sure if it's wastegate like or adjust timing or what but it does it within milliseconds). Might be a good idea for the boost crowd...save an engine, maybe? Just a thought.
|
I really need to get with the times, hugh?
|
WOW!!!! this what I have been waiting for. I will just have to wait a little and see how this works out. Sure sounds great!

Forced induction is not cheap. I am curious to see what you 6'er guys will be running with this combo when it is available for you. Should make things a little more interesting.
|
|
Forced induction can be cheap, my other ride has a holset hx35/40 turbo with custom manifold, downpipe, external gate, standalone fuel and spark, msd, cam, nitrous, huge ic, 1000cc injectors, and all of that still cost less then then 4 grand. They are talking about a charger, bracket, tune, and single maybe cold start injector (either way 12 volt extra injector) for 4 grand. You see why I am a little leary?
|
|
Where else can you go for approaching 100 hp for four grand? No where.

I went there, and to my surprise, the motor is done in Marshall, Virginia, a town of only 600 people where I grew up as a boy. A small, small, world. |
|
it seemed like the trunk was filled with water - kind of a weight shift would happen late - then again, it likely had more to do with the amature behind the wheel of someone else's expensive car....

Shiloh - my advice (I know you didn't ask for it) - until you are running careful about mentioning what is and is not included in the kit. Focus on getting up and going - it's an exciting project and the first for the V6s.
IMHO - Tuning is an absolute must and that can only be done by a SCT tuning device (and likely a shop who tunes using the SCT products). You can get better performance by running closer to MBT (minimum for best torque) spark or LBT (lean best torque) fuelling. The LS already runs LBT fuel (approximately 12:1 air/fuel ratio, compared to the normal stoichiometric 14.6:1) at wide open throttle (or wide open pedal for 2003+). Spark is normally the minimum of MBT and "borderline" (the spark level at which knock begins occurring). This is normally the only place where there's room for improvement from the PCM. But running closer to MBT when you're borderline limited would mean running higher octane fuel. But the LS already runs on premium, so we do not have as much room to wiggle. So you will not have as much PCM automatic adjustment to compensate for the additional air you are injesting since we are already running close to the limits in stock form - hence the need for tuning and the fuel system upgrade. Working in the cost of the additional tuner, fuel injectors, tuning, ....etc. Think of it this way - if you were going to add N2O for an extra 75hp you should not simply add a dry system (hoping the fuel system would some how compensate and add more fuel - you would have to go wet to add the additional fuel since our fuel system are already running near their design limits. Gone are the days where the PCM and injectors has a 25% play. So your BDT is doing the same thing - adding more air. I'm sure Robert can explain it better.... |

Heck, even just on 100wetshot of nitrous I was at 91%+ FPDC (fuel pump duty cycle) which is not maxxed yet, but still closer than I prefer to come to limits while remaining safe. I try to keep all items to a safe max of 85% duty cycle or less.
|
On the topic of forced induction on the LS, whether BDT or supercharged, has anyone experience problems with increased crankcase pressure, i.e. dipstick popping up or out, oil in the intake, front or rear main seals blowing in extreme instances?
|
|
Nope. I vent my cam cover to atmosphere to prevent that with the turbo. The tuning will be slightly different because of it but it is not problem at all. I vented to atmosphere even when N/A while running nitrous too.
If you want you can always run a oil/water separator and a one way check valve and keep the cam cover venting back into the intake. |
|
No problem with the un-metered air affecting your idle quality?
On my Mustang, originally after installing the S-trim I used the Steeda oil separator. I ended up putting a second PCV in the left valve cover with the Viton check valves in both lines. No more oil in the intake. |

If I recall correctly, I believe this guy was only talking about getting something like this done on his V6. So you guys asking about the V8 may not get much out of this thread.
|
|
Even if he is only referring to the V6, I would love to build a V6 Manual Turbo
