Re-inventing "San Pedro" Part 1 (Updated)

There are cars that find new life as race cars, and then there are cars that are practically delivered straight to the track. This 4th gen Honda Prelude (BB4) is a very storied car that's been a race car its entire life -- winning a few championships in the hands of Bob Endicott (it was Bob's car). We are currently reinventing this thoroughbred race car for its next chapter -- which is sure to be very interesting! :)


Orange is the color of the year over here at King Motorsports. The Prelude race car project -- nicknamed "San Pedro" -- is geting a fresh paint job in a bright new color. Some call it Hugger Orange, we prefer to call it Daytona Yellow!! Here it is over at Don's Auto Body in West Allis, WI (Don does all of our paintwork, give him a call at 414-541-5155 if you need anything).




Next stop back to KMS for final assembly and setup.



Now that "San Pedro" is back from Don's Auto Body with a fresh coat of Daytona Yellow (some call it Daytona Red), Chad begins final assembly. Installing the fuel bladder, rear tin work and a set of freshly rebuilt and revalved Penske triple adjustable shocks are the first on the build list.



Fresh new parts and fresh paint-wonderful!!



Rear tin work-bead rolled to eliminate vibration noises. Dzus fasteners are used for easy access to the fuel systems.



We just installed the engine/transmission assembly into "San Pedro" Trick transmission with carbon synchro's and a Mugen limited slip (super rare). The engine is built to the limit of SCCA EP prep rules with a camshaft set ground to our specifications. We'll be using a Hondata S300 for tuning. Can't wait to get it on the dyno!



Getting closer to firing up San Pedro for initial engine break in on the dyno. The engine is now completely plumbed and the engine harness has been installed.



Fitting an oil catch tank on a Prelude is always tricky. We fabricated our own and plumbed it with Aeroquip -10 braided lines.



Here is where we vent the H series valve covers. Here the motor has a race header that DC built specifically for the car years ago. We will use it to establish a baseline before we start developing our own race header for it.



The fuel cell is completely plumbed. We ran a hard line under the car to the engine bay for the fuel feed and return. Connections are -6 Aeroquip.



The Penske triple adjustable damper canisters are mounted for ease of compression and rebound adjustments. Controlling wheel movement is the one of the most important considerations in making a race car handle properly.



Just started fabricating the dash for San Pedro. We use .080" sheet aluminum. We will mount an Autometer tach, oil press/temp and water temp gauge in this panel. Once fabrication has been completed we will send it out to be powder coated flat black to reduce glare.



View from the top of the dash.



San Pedro is alive!! The engine has been broken in on our dyno and we are now testing various intake and exhaust solutions.



It is critical that the initial start and break in of a new engine be monitored closely on the dyno with a wide band. We have seen far to many engines ruined by improper A/F ratios and poor "base line" tunes.



Chad is busy fabricating a new H23 dyno header for San Pedro...



On the dyno with San Pedro with our new H23 stepped race header.

Finishing up TIG welding the 3" stainless race exhaust on "San Pedro" with a Magnaflow 3" stainless muffler.



Here is the header to Mid Pipe Flex Joint.



Some finishing details on "San Pedro" dash is in and gauges wired up.



Fuel filler fabrication.



Interior tin work completed and plexi windows fabricated and installed.



We rebuilt San Pedro's front suspension using new uprights, bearings, hubs and upper control arms. ARP extended studs were also installed.



More updates will be added to the blog as we go. Be sure to check out our Facebook page to see the updates on San Pedro as they happen!


Update 12/4/2012:


We haven't had an update on the progress of "San Pedro" in a while. Christmas came a bit early yesterday in the form of the correct steering hub to mount the steering wheel. We even hear a pair of factory side skirts are on their way to us. "All" we have to do now is fabricate a carbon front air dam to mount the splitter and it's off to the races!!



Update 12/13/2012:


Here's a picture of the newly-painted Volk TE37's with Hoosier race rubber:



Update 12/21/2012:


We are finalizing chassis setup on "San Pedro" -- this orange beast is on the scales and will soon be ready for testing!



Update 1/9/2013:


Finally... San Pedro gets a new windshield!



San Pedro sees the light for the first time in 2013! Spring testing is coming soon!

Mugen Integra Type R (DC2R)


One of our favorite Hondas is the DC2 Type R (DC2R). Mugen fitted new aero and performance parts to improve upon Honda's already formidable track-worthy Integra Type R. The aero kit fits the JDM front clip and features an aggressive, taller wing. Bronze 16" MF10 wheels and suspension upgrades make sure this lightweight Integra transfers power from the Mugen-equipped motor to the pavement.


Three-quarters rear view: clean, simple and functional!



This Mugen sketch illustrates the aerodynamic theories supporting the bold design of Mugen's functional aero body parts for the DC2R. We love how the Mugen front bumper cover and hood work together to pull hot air out of the engine compartment.



Theory is put to the test in an aero analysis in a full scale wind tunnel. Form follows function!

Quiet Fury: Mugen Twin Loop Exhaust Systems

Poll any driver of a Honda B Series what their favorite exhaust system is and you're likely to hear "Mugen Twin Loop" as a top pick.


Here are a few rare pictures of the genuine Twin Loop as seen in Mugen's showroom in Tokyo.



In this cutaway you can see that the pipes are looped back through muffler chamber a second time. The theory behind this unique muffle is based on low frequency sound waves canceling the high frequency sound waves. Because this dampens the sound so effectively, the muffler can be very unrestricted and still be nice and quiet. The tone of the Mugen Twin Loop is truly amazing -- almost musical!



Here is a cutaway of the Mugen center resonator. The workmanship is brilliant!

Mugen Facility Tour: Exhaust/Header Fabrication Shop

Today we're taking you on a short tour of the Mugen exhaust/header fabrication shop. Located behind the main showroom in Tokyo, this ultra clean and efficient facility is where all the Mugen headers and exhausts are fabricated.



All Mugen exhausts and headers are constructed from polished T304 stainless steel, including all attachment points. T304 is considered the best steel available for corrosion resistance and all-around toughness. The flanges are cast stainless steel and use OEM gaskets and hardware for a precision fit.



Each exhaust and header is TIG welded on an extremely robust jig to ensure absolute perfect fitment.



Here a center resonator is packed with sound deadening material before being welded to the B pipe:



The finished product is racked before being packed up for shipping. This represents a typical production run of B Series headers.


 

 


You can check out the currently available Mugen exhaust components in our online store. You can also order a custom header made by King Motorsports. In the tradition of the Mugen headers, the dyno-proven King headers are hand-fabricated with T304 steel for any H, B or K Series and built for perfect fit and maximum horsepower gains.


 

Awesome Display of Power: Honda Motor Anatomy (Updated)

The single day that garnered the most "Likes" on our Facebook page was the same day that we posted some amazing motor images. These iconic Honda motors are disassembled and perfectly laid out like a vignette of some mad motorhead's secret underground lab. His workbench a clinical and spotless automotive gallery of every bit and bolt in these beautiful Honda motors.


If Dexter or Hannibel Lecter were Honda tuners, this is what their secret garages might look like.

Shipping Mugen: Arrival!

 

In late November we posted up pictures of the prep and loading of a special Mugen shipment leaving Tokyo. We're happy to say that the shipment has officially arrived to our facility here in Wisconsin, USA!


Although this shipment contains a variety of Mugen parts, the lion's share of the cargo allocation was for the FRP Mugen S2000 hardtops. We've already pre-sold most of this shipment's hardtops and they will head out to customers very soon. The remaining hardtops will go fast so if you've been eyeing one of these quality pieces, now's a good time to order since (for now) they are in stock and ready to ship!

 

Here are pics of this latest Mugen shipment, freshly unloaded in the warehouse area of our facility! You're looking at ten Mugen S2000 hardtops, Mugen wheels, Mugen SS S2000 bumpers, DC5 aero and more ...
