Michigan 968 SC
#1

I finaly finished the install of the Design One Super Charge kit. I've finished the break-in miliage and have done about a hundred miles of unrestricted RPM, all I can say is WOW. I'm loving this and can see trouble with the local traffic court people in my futrue. This kit makes the car come alive at all RPM's. I've got a DE in a couple of weeks and can't wait.

The kit is well designed, well thought out, with clear directions and performs as advertised, I'm happy.

A few thoughts on the install. I made several mistakes, all do to being in a hurry.( I had a 3 week , out of country, work trip and wanted to complete the job) Don't hurry, take your time. I pumped most of the Rotex traction fluid out on the floor because I wanted to "SEE" if the fluid was pumping thru-out the system, It pumps and starting the engine and going to look at a disconnected hose resulted in a puddle on tyhe floor. I had to purchase more and It's expensive, so caution.

SC belt on the wrong side of the alterneter, the instructions show the correct way, I just needed to look.

Read the instructions three of four times, it helps.

One pin on the DME chip not in it's pocket, results in a no start, head scratching and removal of the DME again.

A couple of tips. Have the head refurbed with a new head gasket, Injectors cleaned and balanced, all hoses replaces, engine clean and leak free. I did all of this the past winter anticipating the SC install.

Carfull when cutting the "charge pipe adaptor boot" it cuts easy with a sharp knife, if you slip you'll need a new one. I know.

One last thing, If the any of the "intake pipe" hoses want to kink, once kinked they will continue to want to in the same place. Get a loosly wound spring, from ACE or Home Depot. It's OD should match the ID of the hose, Slip it in the hose at the Kink and no more kink.

Is that engine routinely inspected by th local health department - or is it in a surgical ward. Man that is clean.



100 out of 10 for cleanliness in that engine bay. I am blown away.

taht is pretty danged clean



one install note: i thin i would run the MAF cable underneath, just to protect it from movement and such - failing that, i would at least zip tie it to the hoses

The <acronym title='mass air flow'>MAF</acronym> cable is zip tied, and I really went over all hoses and cables for clearance being secure after reading about Banditsc's rubbed threw SC oil line, I will look at it again to see if I should move it.

The engine compartment is clean because I don't like getting dirty hands, LOL. I do all my own wrenching and have been "in there" Multiple times for all of the 968 issues. The car was basically junk when I purchased it, I hauled it home , not running. It took a year and a half to get it on the road, Thank god for this and .net forums

Can you try to describe the "seat of the pants" before and after(HP)? Are you running aftermarket exhaust?

I'm running a RS Barn "cat back" system. I had the full stage two exhaust and chip, but removed the header and re-installed the cat when I did the SC.

I would describe the feeling as more torque at all RPMs, It just pulls better and sets you back in the seat quicker at a lower RPM. I will be doing a DE in a couple of weeks and I would venture to guess, as least at this track, I won't need as many down shifts or second gear corner exits. Will see and I'll let everyone know.

It also makes this lovely sound like there is an F-18 somewhere above you <img src="/forum/images/smilies/968/wink.png" class="smilie" alt="" />

On the hose kink problem I ended up putting a hose clamp on the largest hose and tightening it just enough to force the hose into a round state.

I found some hoses with 90 degree bends of the proper sized and cut and spliced so they turned the corner nicely.

just be sure that those bends don't reduce the inside diameter, especially on the idle control valve - that thing needs all the air it can get
