D1R SuperCharger Install
#1

<!--fonto:Calibri--><!--/fonto--><!--sizeo:3--><!--/sizeo-->The D1R S/C kit is now installed I wanted to share the experience so far as well as my observations with the install process, fit and trim of the kit, and just how drivable the car is with it. I can't thank Flash enough for the amount of work put into this kit and for letting me watch him install it in my ride.<!--sizec-->
<!--/sizec--><!--fontc--><!--/fontc-->

<!--fonto:Calibri--><!--/fonto--><!--sizeo:3--><!--/sizeo-->The process started Monday afternoon with a trip to Kraftwerks in Norco, CA for a dyno run before install, to see what the stock configuration baseline was. As this was my first dyno experience and I'm not the kind of guy that has ever wanted to build/rebuild a motor on my own, I must admit that watching/hearing my car run up on the dyno made me nervous, even though the head was freshly rebuilt. It was only 109 degrees F on the drive there, so maybe heatstroke contributed to the anxiety. I will let Flash post the "before and after" dyno data with his commentary. Monday night had the bat wing, belly pan, airbox, and fans out.<!--sizec-->
<!--/sizec--><!--fontc--><!--/fontc-->

<!--fonto:Calibri--><!--/fonto--><!--sizeo:3--><!--/sizeo-->Tuesday install started around 7am and we were test driving by 3pm, inclusive of lunch, breaks, and cleaning of engine parts and surfaces along the way. I must say that this kit is a true Bolt-On. Not a single hole needed to be drilled or body panel cut required. Everything fit just as it was supposed to and the kit looks like it belongs in the car. Equally impressive is the fact that after installation, the car went straight to idle on the first turn of the ignition key; no hesitation or hunting at all. The drive back to the dyno shop in an unbearable heat proved that the A/C was still fully functional, and by 7pm the "after" dyno runs were complete.<!--sizec-->
<!--/sizec--><!--fontc--><!--/fontc-->

<!--fonto:Calibri--><!--/fonto--><!--sizeo:3--><!--/sizeo-->The drive home was almost 150 miles on socal freeways, giving me a chance to get a feel for this modification. As promised, the added torque is felt right away and where I drive it most - between 3k rpm and 4k rpm - in freeway traffic. It is smooth across the gearbox, and in a word "Civilized". It's subtle in that added acceleration [power] is available at any RPM and you don't have to push it above 4k to get it going. Conclusion: Guaranteed to induce a $hit Eating Grin

Thanks for the report. I can't wait to get mine back from RSBarn and have the same grin on my face.

i loved the fact that even in that blistering heat, the car ran cool, even with the AC on, and in stop and go traffic

i will post the charts when i get them - they haven't sent them to me yet

just wait until you get to drive it in cooler weather - between the AC being off, and gaining back the 20hp you lost to the heat, it should be a ton of fun

Can hardly wait, we never get over 30 (one week) and always hover at 10-25 most of the year. Living in BC is like having a permanent intercooler [img]style_emoticons/<#EMO_DIR#>/wink.gif[/img]

i have now put 450 miles on since installing the s/c and it's made the car that much more fun to drive. we neglected to do a blink test before install, and now having a hard time determining if an intermittent knock sensor was a 'pre-existing condition' and whether it has any effect on overall performance. we'll swap the sensor and hope all will be well.

my latest observations: (1) rotrex oil is impossible to see on the dipstick that's built into the resevoir cap, (2) the s/c makes a very distinct sound and i think its coming through the vents in the center of the dash, and (3) my radar detector is getting more work now.

me thinks the RSB Catback is the next necessity...

Jeebzus... That's a crime! Please, for the love of all that is good and pure in this world, send your car to me immediately. I will rid your lovely car of that wretched abomination post haste -- I'll even pay for two-way shipping of your 968.

I would do this, for you, because I care. That's just how I roll...












Everyone be quiet - I think BVA might actually be taking the bait.... [img]style_emoticons/<#EMO_DIR#>/wink.gif[/img]










Seriously though - congrats - install looks great! Enjoy the system and the new ride! I am jealous! [img]style_emoticons/<#EMO_DIR#>/smile.gif[/img] [img]style_emoticons/<#EMO_DIR#>/mad.gif[/img]

??? i don't have any noise through my center vents - i wonder if the plastic piece that covers your heater box is sealed fully?

Bandit,
thanks for confirming the sound thing - Flash, me thinks you've had more time to get used to it.

Bio,
surely you're referring to the yellowed coolant expansion tank - its a perfect match for your ride.

lol - nope - i've been listening for noises from day one - while i have noises, that isn't one of them - both you and banditsc have late cars with filters - i am wondering if the heater is different and allows more flow in later models?

as for the knock sensor, i am positive it has nothing to do with the kit, but we, or the mechanic who did the head work, may have knackered the wiring while installing

I do have a rubber seal I guess you would call it, it's the one that sits on fender and on top of the firewall seal, that is missing. It's on the passenger side where the air intake would be, maybe that is some of it. If I ever find the part number for that piece I will get a new one.

bva's car has a loose fitting seal too - it doesn't take much to let engine noise into the heater box - but, if you are talking about the rubber block, that is likely not it - it would more likely be the one that basically glues down the large flat plastic sheet that is the top of the box - this frequently gets knackered when somebody changes the filters

That one is fine on mine, it's the block that I'm missing. I just moved the remaining block to the right side, see what happens. Someday I will find that stupid little block in PET.

banditsc - I was already on to Pete to find out exactly what exhaust pieces you ordered. It sounds to me like not getting the exhaust system right from the start you are doing the SC install a disservice.
