LT Headers and Supercharger
I've got a Saleen supercharger, and i'm going to be adding some long tube headers in the near future. I was wondering if having the supercharger on the car is gonna cause any extra difficulty on the install. I need to know so when I get quotes from shops that don't try and up charge me for extra work id there really isn't any.
Secondly, i have a custom tune for the SC will my car run ok without a new tune until i can get it on the rollers again, I also have a wideband a/f gauge so i can watch it and possibly tweak it if need be with my predator, is this feasible or am i dreaming?

RE: LT Headers and Supercharger
There should be no reason to charge extra for an LT install IMO. As far as your tune goes... from what I was told when I inquired the same.... you should be ok... to really take advantage of the additonal airflow that will occur get it back on the rollers ASAP.... one issue that I had (and did not go with LTs as a result) was the added power potential was going to cause me to run out of fuel.... I have a BAP... So to really take advantage I was looking at the GT500 pump upgrade and maybe an upgrade to 60# injectors. If I did all that... we guessed I'd see a 40-50 rwhp bump.

You do not need a new tune for the headers.
When using a less restrictive exhaust system you are likely to lose 1/2 to 1psi boost because of the reduction in back pressure you can compensate with a smaller pulley.
If your LT's dont include extensions you'll need to get them if you want to use the O2 sensors, otherwise you can use a tuner to turn off this function.
Chances are you'll get O2 engine codes because the O2 sensors will be now located further back, especially during cold starts. SO i vote for turning off the O2 sensors.
You are to expect a much louder exhaust because of the SC/LT's combination.

You are not going to have any mechanical issues installing LT's on a SaleenSC'd car.
