Dyno Day 2013 Recap

This year's Dyno Day got an early start as attendees took our advice and showed up on time. :) In fact we had people arrive an hour early to chill with their friends as we set up the check-in booth. We had 224 registration goodie bags to hand out -- and we had nearly as many cars. Dyno runs ran through the day in the shop, with live video feeds piped into our showroom. In the showroom we had a rare and one-of-a-kind display of Mugen and King nostalgia prepared especially for Dyno Day. Some of these items have never been publicly displayed.

Deletah was once again on hand to fill the deepest parts of your ears and hearts, and Andy Noggle was on hand as our event photographer. Boy Scout Troop 93 served up BBQ chow as raffles and nice sponsor prizes were given out throughout the day.

Rounding out the event were show awards for Farthest Distance Traveled (William Wang from New Hampshire), King of the Dyno (556 HP daily driven Supra), Staff Pick (red EF Civic hatch), People's Choice (black 499 HP turbo S2000) and Lowest Pull (CR-Z at 122 HP).

During the day we offered 10% off all in-stock items and had a few garage sale items for sale -- including the motor out of the King Motorsports RSX Challenge Car.

We caught a nice break in the weather too. The sun was out just enough to bring out the shine on some amazing rides.

Thank you to all our many sponsors, attendees and volunteers who helped make the event so memorable! We're already at work planning the 2014 Dyno Day!

 

Jon L. sent us this awesome video recap of Dyno Day featuring a few camera techniques we've never seen before!

San Pedro: Debut Race! (Updated w/ Vid)

Our Prelude race car project known as San Pedro recently had a great day of testing at Gingerman Raceway. Once back at the shop we did some fine tuning and adjustments based on what we learned.


We prepped spare noses/airdams and splitters in anticipation of San Pedro's debut race at Michigan International Speedway in two weeks.



5/25/2013: San Pedro wins its first National SCCA EP race from the pole of the 2013 race season at Michigan International Speedway today complete with a new lap record! Congrats to Moser Racing - awesome result!



5/26/2013: Day 2 at Michigan International Speedway. San Pedro wins the qualifying race by 39 seconds! Way to go Moser Racing!



Day 2 at Michigan International Speedway and another flag to flag win for San Pedro and the Moser Racing team! Way to go guys!!!!


San Pedro captures the pole in its very first SCCA EP National race of the 2013 race season- pumped!! Go Joe Moser!!!




Fun San Pedro factoid- Top speed at Michigan International Speedway on the banking was 144 mph. Entry speed into Turn 1 off the banking was 62 mph. San Pedro brakes from 144 mph to 62 mph in 63 feet!!!!


The Mosers have posted the video on Youtube!

Engine build: EV 1.3 HF

In the King shop last week! We finished up an old school EV 1.3 HF build. This engine will soon be installed in a beautifully restored 1985 HF.



The tricky part of an old school engine build like this EV 1.3 HF is a shortage of OEM rebuild parts- they are getting very scare.

 

Because 1st. over bore pistons are no longer available, we commissioned Wiseco to build a forged piston with the exact dimensions of the factory piston with the bore size we needed. We stress relieved and deburred the factory connecting rods and the whole rotating assembly was balanced to our specifications.



The EV 1.3 HF cylinder head ready for final assembly. Valve seats were carefully blended and just a touch bowl work to increase efficiency. Will 50+ mpg be a reality using yestertech?



We also got this info & picture from Yawsport:

"Captured fresh out of the paint booth over 1 year ago, this champagne Honda Civic 1300 Hatchback (affectionately named "Champ") will adorn the fully blueprinted EV1 engine currently being finished up by King Motorsports. It's been a long road to find some of the engine internals needed to complete this detailed build, but it will definitely be worth the wait. Stay tuned for the full write up of this project as well as some custom suspension goodness."



The EV 1.3 HF engine is almost buttoned up and looking terrific!

Chris K.'s Mugen Del Sol

Return of an old friend! Yesterday, long-time King Motorsports customer Chris K. brought in his Del Sol that has been in storage for many years.

 

We are in charge of bringing it back to life. Years ago we installed a Mugen B16B N1 crate engine and well as a cool set of Mugen MF-10L mirror face wheels. Since then, Chris has collected all the Mugen aero parts as well as some other really cool period Mugen bits. Once complete it will be a stunner!



Awakening the beast after many years of storage. Chris K's Del Sol equipped with a Mugen B16B N1 crate engine, Mugen valve cover, Mugen header and plenty of other rare Mugen bits.

San Pedro: Unleashed for Testing



We put our Prelude race car project known as "San Pedro" through the paces for testing at Gingerman Raceway this week, and the results were fantastic!



San Pedro's driver's office. Easy to read analog gauges, GPS based data aq and adjustable brake bias. Uncomplicated and clean!




Testing going well. First set of Hoosiers are now history.... :)



Starting to use some brakes.... Huge brake ducts and trick race pads. This is way they should look when you use them hard!



The driver says there was a balance problem. The crew refers to this as driver running out of talent :)

For the record, we are extremely happy the driver wants to push the boundaries of adhesion. Sometimes that means going over the limit to find exactly where that limit is. That's precisely why we go testing! We have plenty more splitters where this one came from (it helps that we made our own).



That's a wrap from Gingerman Raceway! We learned what the car likes and finished up 2 seconds under the lap record. A very good day!

Re-inventing "San Pedro" Part 2 (Updated)


We've had so many pictures to share of our 4th gen Honda Prelude race car project (dubbed "San Pedro") that we've decided it's high time to start a new blog post! Welcome to "Re-inventing 'San Pedro' Part 2"!


Update 1/18/2013:


This week we have been working on building the plug from which the mold for the front air dam will be made. The airdam will provide a platform to mount the front splitter once completed. Here we are roughing out the foam core to the basic shape we are looking for.



Once the basic shape has been roughed out, Bondo is applied and sanded into a finished shape. This is a very time consuming process as the entire air dam has to be symmetric -- with a perfect surface finish. Up next, building the mold from this plug and making finished pieces out of carbon fiber! Stay tuned.....



Update 1/24/2013:


Work continues on the front airdam plug. After numerous coats of Bondo and shaping, we are getting close to a finalized shape. Next step is several applications of high build primer and sanding to make the surface of the airdam plug absolutely perfect with no pin holes or sanding marks. This is roughly what the airdam it will look like when attached to the front bumper.




Update 1/30/2013:


We have now completed the plug for the front airdam mold. Before the mold is made from this plug, it will be liberally coated with wax and then with a mold release agent so the fiberglass used in making the mold does not stick to the plug.



Here is an example of what the final mold looks like. The molds are designed to have great strength so there is no potential for any dimension of the final part to change during the lay up process.



The next step in producing the airdam for San Pedro is vacuum bag moulding.

Vacuum bag moulding uses a flexible film to enclose the part and seal it from outside air. A vacuum is then drawn on the vacuum bag and atmospheric pressure compresses the part during the cure process. Vacuum bag material is available in a tube shape or a sheet of material. When a tube shaped bag is used, the entire part can be enclosed within the bag. When using sheet bagging materials, the edges of the vacuum bag are sealed against the edges of the mould surface to enclose the part against an air-tight mould. When bagged in this way, the lower mold is a rigid structure and the upper surface of the part is formed by the flexible membrane vacuum bag. The flexible membrane can be a reusable silicone material or an extruded polymer film. After sealing the part inside the vacuum bag, a vacuum is drawn on the part (and held) during cure. This process can be performed at either ambient or elevated temperature with ambient atmospheric pressure acting upon the vacuum bag. A vacuum pump is typically used to draw a vacuum. An economical method of drawing a vacuum is with a venturi vacuum and air compressor.

A vacuum bag is a bag made of strong rubber-coated fabric or a polymer film used to compress the part during a cure or hardening process. In some applications the bag encloses the entire material, or in other applications a mold is used to form one face of the laminate with the bag being a single layer to seal to the outer edge of the mold face. When using a tube shaped bag, the ends of the bag are sealed and the air is drawn out of the bag through a nipple using a vacuum pump. As a result, uniform pressure approaching one atmosphere is applied to the surfaces of the object inside the bag, holding parts together while the adhesive cures. The entire bag may be placed in a temperature-controlled oven, oil bath or water bath and gently heated to accelerate curing.



Here are rolls of carbon fiber material that will be used to make the final airdam.



Daytona Red race cars have taken over the shop today!




Update 2/26/2013:

San Pedro update! The mold for the front air dam has been completed. Notice the robust construction of the mold to insure there is no chance of a core shift. Pictured is the backside of the mold. The upper and lower half are bolted together and then unbolted to release the final part.



Here is the inside of the front air dam mold for San Pedro. The surface finish has to be glass smooth as your finished part will pick up any imperfections.



A look at the first carbon fiber air dam out of the mold for San Pedro. Next up fitting to the car and measuring for the splitter plank....



Update 3/26/2013:

The front splitter/airdam is now complete and mounted. Next up building shrouding for the radiator, brake ducts and an airbox...



Update 4/3/2013:

In the shop today: TIG welding the aluminum airbox for San Pedro.




Update 4/4/2013:

Yesterday we bid a fond farewell to San Pedro. Next week we'll be testing San Pedro at an "unidentified" race track working various chassis setups. Here are a few photos before San Pedro was loaded up to head to its new home.



San Pedro basking in the sunlight after a winter makeover...



Detail shot of the front airdam/splitter profile. Lot's of downforce to be expected. How much? We shall soon see :)



All that's needed is the spacer between the seat and steering wheel :)
