Hahn's setup places the MAF sensor in the ic-tb pipe and vents the pressure before the ic into the atmosphere with a blowoff valve (therefore venting before passing the MAF sensor). I think the advantage of this would be more accurate readings from the MAF sensor and probably better overall performance of the fuel management system.

Bill i have a some questions for you also:
1. if we were to installt his kit ourselves ( i will most likely do this becuase i think it would be fun and no one where im at will do it) , how hard of an installation am i looking at...others have said it shouldnt be too hard....and im wondering how hard you think it would be...
2. if you could could you get us a round-about price of what this kit will cost?.....most of us speculate around $4000....is that correct or no?
3. for your oil supply and return lines to the turbo...did you have to make any special taps or were there already allowances made in the oil pan for these lines ( i think some1 posted up a pic of a pre driled hole sealed of for tapping)....how hard was that to do?
4. i dont know if this would work but couldnt the intake be re run to the front left fender?....although that would require new piping and further delay production...
5. is that fuel rail your using the stock fuel rail or a new one....it doesnt look stock to me...?
6. and last what is your reason for puttin the MAF in the ic-tb piping...i personally think it is good idea becuase of cleaner and cooler air but i am curious what you have to say about that?
overall the pics look great and i cant wait to get the turbo kit....keep up the good work and i look forward to some answers...thanks

The problem is, with the engine installed in the car, it is damn near impossible to get a drill up there, and then to tap the threads. Also, if you have an automatic trans, even if you did have that hole tapped, the trans blocks any ability to run a line there.
SO... Instead you drill and tap the oil pan directly above the pan drain bolt, which just so happens to be directly below that dimple on an assembled engine.
Remember, this an L61 engine. I don't know if the LE5 has that dimple, but I'm betting you still tap the oil pan in the exact same spot.

Mike, here's some answers:
1. Most of our systems are designed to be installed by either skilled enthusiasts or pro mechanics. We exhaustively document and detail the systems, with the best instructions and tech support in the industry. As it's effectively impossible for me to do anything more to evaluate your personal skills, suffice to say...if you have a pro auto mechanic friend looking over your shoulder to keep you out of trouble, then doing your own installation should be fine.
2. You're in the ballpark!
3. This system features a new approach we have developed for oil feed and return that is the easiset yet. No oil pan removal, no drilling onto the engine itself!
4. Frankly, at the power level of a Stage II, the current air filter location is no problem. The humongous intercooler is amazingly effective at these power levels. Re-configuration of the air inlet is just unneccesary expense at this juncture. For higher power levels, we'll be looking at airbox or other cold air inlet possibilities.
5. Yep, that's a stock fuel rail. These new sheetmetal fuel rails are awesome!
6. We've found that this is where the MAF works best based upon rather exhaustive development.
Thanks for your interest!

Hello Bill Hahn
Not to jack this thread but could you please take a few moments and give your expert opinion on twincharging the LSJ, either in this thread or this other thread.
https://www.cobaltss.net/forums/show...d=1#post425199
This would would be very helpful and insightful for those of us going this route as well as all the nay sayers.
Thanks,
Rod

Ok guys, i should have the video here on Saturday, (pending weather conditions) so be ready to see what she sounds like with a 3" exhaust, and what she looks like with custom powder coated pipes!!!!
