Yes...after much deliberation, I wimped out and followed the crowd. I now have a clean, shiny 3.6 Varioram motor living beneath the bonnet. I opted for factory reliability and driveability over boosting a 78,000 mile 3.2. After 5 months and 3 DE's I couldn't be happier with my decision.

I'm with porscheboy 16. I'm biased because I went the Protomotive route, but I couldn't be happier. Working with Todd is fun, and the product is really first class. I believe turbo is better than SCs- turbos have become mainstream- they are on tractors, boat engines, etc, and the technology is really proven reliable. SCs are somewhere out in left field IMO. I am installing the system myself and saving a fair amount of $$ and having fun doing it. The Stage 1 is a complete system that includes heater mod, software, and fuel regulation in addition to the turbo, headers, wastegate, and muffler.

Charles,

So I take it that you have done the Proto Stage I? Man, I have to see your car, where in MD do you live? I have an '84 Carrera being converted to Turbo Look at Karosserie in Fairfax, VA. To fill the void while it is being created, I picked up a British Racing Green '84 Targa. I might go the Proto route in about a year with the Turbo Look.

I'm in Bethesda. I'm also doing the Protomotive intercooler but saving some $$ by avoiding some of the "bells and whistles" (mechanical vs electronic wastegate, etc). I can't speak to performance yet, but the Protomotive stuff is very, very well designed and constructed. Here is my baby:http://www.pelicanparts.com/pmpre/im...slant_nose.jpg

Hey Jurgen, I like your idea :)

What is the link to Promotive site?

Charles, Nice car.

Not to nitpick but SCs have been around quite a bit longer than turbos and are also well proven regarding reliability. In fact the Roots type SC was invented in the mid 1800s. Also, many would argue that SCs are more reliable and easier/cheaper to plumb.

I don't mean to take away from the positive attributes of the turbo as this is the route I'm (casually) taking. :)

BTW, do you have any pics of your system on or off the car?


Here's an excellent link on Turbo and Supercharging, including a comparison of the two...... http://www.lextreme.com/Turbo.htm

Yes, I've got lots of pictures. What would you like to see ?

I have been running a SOK supercharger on my 3.2 for about 5 years though the mileage on it is only about 7,000 miles. I have just torn down the motor because I was starting to get blow and a leak down test showed internal problems. What I found was that the motor had broken ring lands. Now I'm told that the compression was too high with the stock pistons to sustain the boost. I have read others have had this problem and wondered what they did to resolve it?

Use the appropriate pulleys to lower the boost?

Since Supercharging of Knoxville installed the kit, I made no changes to it. Did I miss something?

SUPCHG911 please email me! Which SC do you have?

Hello Kdubb!
I also have the Paxton unit. Looks just like yours without the fancy serpentine pully. How has it been working for you?

For the first 3 years (not driven too often- new kids) it was fine......and then I developed an oil leak like you would not believe. I spoke to SOK about the problem which was never found. I ultimately rebuilt the top end, and everything seems ok now. I have a ROW Pcar. It was probably the Comp Ratio. Of course SOK defends the reliability of the SC's.

PM me. I am in Northern Indiana at least once a month. Let's speak off line. I will give you more details about this problem. PM me your number.

wow, 10.3:1 plus supercharger? how many psi? What fuel and any pinging?

Compression ratio too high, fuel octane level too low, boost level too high, etc. SoK should know better than to intall a kit on an RoW motor without warning you and lowering the boost level for safety.

CR is 9:5. Boost is 7 PSI. Fuel quality was probably an issue. SOK was more interested in selling their kit then in customer service. I immediately had a problem with the system that they installed as soon as I got it home and they were less than helpful. I gave up on them a long time ago.

Heard 2nd hand SOK has bad service. I bought my friends 86' 3.2L with Whipple supercharger kit from SOK. Having problems now. need to figure out

I am new to this forum as you can see. Just bought a 3.2 supercharged carrera from a friend in TN. he purchased the Whipple kit from SOK. He had the pistons machined down to 8.9 or 9.0. After break in of 5-7k miles he got a larger pully for more boost. Has put about 30k miles on it no problems. Motor is at 150k now, was rebuilt at 95k when he put the supercharger on.

Now my story.....picked up the car to drive back to Oregon (long drive). Heading over the platau at Flagstaff Arizona which i think is between 6000 and 8000 ft elevation. Going about 110 or so for a prolonged period of time. Smoke starts comming into cockpit. Got the car back home via truck and now trying to diagnose the problem.

Was the compression still too high? worn valve guides, piston rings? Did and was told pistons needs replacing. The guy local who my father knows. says i should not put in machined 3.2 pistons this time, and go with turbo pistons which i think are 8.5? Do you have any suggestions, or have heard any good advice lately? I know for sure that i am going to put in a good Air fuel gauge to let me know if im running lean this time around.

After all of the advice that I got, I think that the compression is still too high. Should be running between 7.5 to 8, but that will depend on the level of boost that the supercharger is putting out too. I 'm sure the thin air at your elevation didn't help things, but I'll leave that to a more techincal Pelican to explain.
