Finally mine is in. I took a lot of time to try and kit it up for all but the intake tube was too much cutting and stretching to be viable...I would have to pull it apart to duplicate it. I don't have my own garage. I went with 3.25" tubing all the way. The larger duct size was a b___ to work with things are very tight near the TB. I used some serious force to move it and shape it with a heat gun. Just thought I would go big or go home! I wanted to minimize losses as much as possible. Be warned that 3.25" is an odd size and if you that route you should make silicon intakes your friend!
Just running it now...yes its one in the morning. The intake roar/rush from the 3,25 duct is scary/strong from idle to 3000 rpm.....have not rolled it out yet. Throttle response is crisp everytime I stab it.....from idle....this is not what I expected but very welcome. Testing starts tomorrow.
Some negatives: my duct is touching (jammed) on my transmission top bolt and engine bay (the price you pay for a bigger diameter; TB plug receptacle is very close to my trans/engine case; made a mess of the AOS tube with the heat gun but it works....it was dark and I was rushing;
Some cautions: I had my inspection mirror under and around the Carrera tee and nearly sent the car jumping...the starter solenoid is right there so don't forget to disconnect the battery!
So far the engine is running ferociously! It took me by surprise when I blipped it...
