Q. I placed an order, when will my product arrive?
A. We ship products same or next business day. Domestic orders typically take 2-3 business days to arrive. We no longer ship internationally, use a forwarding service such as http://www.shipito.com , our packages are 6x9x1 bubble mailers, each keychain is about 3oz in weight.
Q. What is "Mega Spin" technology?
A. All USA KCT-11RS's shipped between 08-28-2009 and 3-23-2010 have an improved main bearing to minimize shaft play and included thrust bearing to promote effortless spin with drastically increasing the turbo spooling sound. This corrected the issue of impeller wobble at faster speeds. Mega Spin has been superseded by ball bearing technology.
Q. What is "Sleeve Bearing" technology?
A. KCT-11RS2 is the latest in the RS product family. The impeller shaft has been replaced with a smooth center pin instead of a screw which the impeller rotates on, and is held in with a C-Clip. Spin rates average around 10,000 RPMs and some do have a little compressor wobble. There is a totally new one-piece backplate that eliminates the center chain screw, plus a much stronger chain. The backplate is bolted to the housing in 5 places. This is the ultimate low-cost most durable keychain available.
Q. What is "Twin Sheld Ball Bearing" technology?
A. All USA KCT-11BB/BB2 (released after 03-23-2010) include an integrated high precision chrome steel twin shield ball bearing. This entrely eliminates shaft play and allows bidirectional rotation. Spin rates are certified to a minimum of 35,000(55,000 for BB2) RPMS @ 3psi. Design limits is 75,000 RPMS. Break-in not required, they've already been run tested at 75,000 RPMs. Use caution and wear eye protection when attaching to compressed air, impeller speeds can quickly exceed 90,000+ RPMs @ .5 BAR. During stress testing catastrophic impeller breakup occurs between .5 - 1BAR of pressure (7-14.5psi). Warranty due to abuse is not covered, such as impeller overspeed, bearing submerged under fluids, etc.. Please use common sense.
Q. What is "Twin Sheld Ceramic Ball Bearing" technology?
A. All USA KCT-11LE include an integrated high precision expensive chrome steel twin shields with ceramic ball bearings. Spin rates are certified to sustain 105,000 RPMS @ 3psi. Break-in not required, these units already been run tested exceeding 175,000 RPMs. Ceramic bearings are extremely light weight which reduces rotational mass, thus reduces friction, heat, energy loss, and warpage that can lead to bearing failure.
Q. Are the RPM's listed on the spec card for real?
A. Yes. Every KCT-11BB/BB2 is tested with about 3psi and the RPM's are recorded with each individual keychain. When air is injected and strikes each blade it generates an audio compression wave. The waves are analyzed in real-time, math is applied to convert the pulses per second into actual RPMs. Most keychains average around 60,000 RPMs during test.
Q. Where can I get a KCT-11BB/BB2 keychain with integrated ball bearings?
A. Only from this website. Most ebay listings are cloned versions of the older non-bearing or sleeve bearing design, some of which require a drinking straw to operate which is just silly. With a certified KCT-11BB/BB2 you will receive a compressor specification card. If it did not ship from Tucson, Arizona, USA, it's probably not a ball bearing version.
Q. I ran too much pressure and by impeller/bearing exploded, can I get replacement parts?
A. Contact support, it depends upon the model. A new backplate assembly may be required.
Q. Is this a real turbocharger?
A. No, it's a keychain.
Q. Does this keychain turbo have moving parts?
A. Yes, it has a spinning impeller. The new GE Series contains a spinning impeller and turbine with interconnected shaft.
Q. Does this Turbo keychain require lubrication?
A. No. But if you want crazy spin rates a light oil such as WD-40 works fine. AeroShell AF2,AF3, or turbine oil is good and used in many aircraft instruments with high speed gyros. We have developed a ultra lightweight oil (uLo) about half the viscosity of AF2 and maintains consistent viscosity over a wider temperature range.
Q. Can I take apart my turbo keychain?
A. Yes, on the KCT-11RS2 and KCT-11BB2 just unscrew the 5 bolts on the backplate. You can then "modify" your impeller and hone out/port your compressor housing with a Dremel to allow greater CFM airflow. If you lose or over torque a screw contact us. The center hex bolt and bearing are permanently pressed-in with precision and adhered to the backplate and is not designed to be removed. The GE Series are a bit more complicated for unassembly and must start by spinning off the turbine blade.
Q. Will this give me more horsepower?
A. Probably not. But you can tell people you have a turbo and technically you wouldn't be lying.
Q. What is this specification card that was shipped with my keychain turbo?
A. We think that's cool too.
Q. Can I purchase these in bulk?
A. The KCT-11RS2 (Sleeve Bearing) spinning turbo keychains are $2.82 each, the KCT-11BB2 (Ball Bearing) are $11.50 each. There is also a $10 flat bulk handling fee + actual shipping. Please contact firstname.lastname@example.org to make sure we have enough inventory.
Q. When will you be able to ship outside the United States?
A. We no longer ship internationally, use a forwarding service such as http://www.shipito.com , our packages are 6x9x1 bubble mailers, each keychain is about 3oz in weight.
Q. Why did you start charging Arizona sales tax for Arizona residents?
A. We use to pay the tax on your behalf, however since most of the AZ residents felt like 8.1 cents per dollar was too low and voted for a 12.4% sales tax increase, we are no longer interested in paying your taxes.
Q. What is the GE-Series Turbo keychains?
A. It's the Grant Evers Series. A new high end addition to the current turbo keychain portfolio that includes a hot side. Both turbine and impeller are interconnected with a ball bearing.
Q. Why do the GE-S1 keychains frequently run out of stock?
A. We assemble a maxiumum of 10 per day. It's a lengthy process similar to hand building a high end exotic vehicle. Each unit has a serial number engraved inside the backplate that correlates to the one on the Turbo Spec Card.
Q. How do I decode the GE-S1 serial number?
A. 1st digit = Year; 2nd & 3rd digit = Month; 4th-6th digit = number. For example: 111023 = 2011/11 Unit 023 of that year (2011); 206624 = 2012/06 624th unit of 2012; 207A35 = 2012/07 Unit #1035; 208B99 = 2012/08 Unit #1199; 212Z85 = 2012/12 Unit #3585
