I’ve had the pleasure and privilege of training various tuners/calibrators across the U.S., and a few in Japan as well. Every once in a while you run into someone that impresses you. Chris Kiewert is one of those persons that impressed me a few years ago when we first met. He was always open to discussing ideas, never made assumptions, seldom got into those pissing matches that tuners tend to thrive on, and he always treated his customers and their vehicles with respect. If he thought he was pushing things with the tune he would explain the possible consequences to the customer and would allow them to make the choice to continue or to back off to keep things safe. He did not let the dyno queens compromise his personal experiences and beliefs. Enough of kissing his ass. ;) The whole reason for this post was to wish him the best on his new endevor, EFILogics.com.

He and some of his associates have put together a nice video featuring some of the successful road race vehicles he has tuned, check it out. Good stuff!

Propane Powered Buggy

I have a few clients that I have known for over ten years now and every once in a while I will get a call from one of them asking if I will tune their new car. These new cars can be their old cars with new hardware or totally new cars. All of these clients are cool…but some are just downright crazy. I was able to tune a great looking FD3S RX-7 a few weeks back. This was a nice white car that had a built 20B (3-rotor engine from a JDM Mazda Cosmo) with a GT42R turbo. On pump gas, this combination was making around 440 WHP on 9 pounds (relative) of boost pressure! These are impressive power numbers on our chassis dyno. I will try to get some pictures and graphs posted later. I also have a group of 20 or so sandrail or dune buggies that I tune. These client are cool as well and ALL of them are crazy IMO. Randy is one of the cooler guys and he has a great looking, propane powered buggy. This picture does not do it justice, I will see if I can find some more pictures. This thing was just scary; 1700 pounds and 310 WHP are too kick ass combinations. I have not been with him to the dunes, but I have heard that he has a very easy time keeping up with (and beating) the various V8 powered buggies. You know, the ones making 600+ HP…ya right. Regardless, below is a picture of the car and the dynograph of this thing running on propane. The buggy runs a built, turbocharged Ecotech engine.

2.3L Spooling a GT37R via Proper Design & Quality Parts!

Posted by admin on 22 Mar 2008 | Tagged as: Uncategorized

Yes, it has been a while since my last posting. I have been traveling, and I registered for some additional classes at the UofU. So far, so good, but I have absolutely NO time for any fun stuff. As the race season starts up, I have to spend more time at our MMP facility tuning race cars and assisting various local race teams with their vehicle preparations. I assisted a Time Attack EVO 9 with EMS tuning using an AccessPORT and our AccessTUNER Professional software. I was a bit excited that I could remotely generate a base calibration, e-mail it to the client, and have them Reflash it to the vehicle…and it fired right up. They drove the car around checking for various leaks and heat cycling the engine, then I drove out there to finish the tune later that day. This car had:

Worth the cost + made in U.S.A    EVO9 with GT37 Turbo

AMS 2.3L shortblock
HKS 272 camshafts (stock head)
1000cc fuel injectors
Full Race GT37R twin scroll turbocharger kit w/ vertical flow FMIC

I gotta say that this engine/turbo system combination performed extraordinarily well. The robotic TIG welds on the equal-length exhaust manifold were some of the best I have seen, inside and out. After initially testing the engine and properly breaking it in on the chassis dyno we proceeded to tune for power. Our final power goals required boost targets of ~30psiG on 110 octane, and this car was achieving full boost by ~3900 RPM. This was not the only impressive part, the transient response of this engine/turbo system was phenomenal. If the driver needed to get out of power then request additional torque, the system would spool very quickly and make power the entire way to the boost targets. Regardless, you always feel good when quality hardware are used, directions are followed, and the cars are presented for tuning as they said they would be.

TAS 2007

Seas of black with the occasional bad dye

At Tokyo Auto Salon (TAS) this week. For those that have not attended before, you should enjoy it if you like the “JDM”, cars, and or girls. Much more like a smaller SEMA than PRI or Autosport. The show is cool to attend as a spectator, but I am a bit disappointed in the fact that most people appear to be here for the girls rather than the cars. I am sure that is because I am more of a car geek rather than a girl geek. I at least have a good idea about what works well on cars, as to where I have no idea what works well with women…kind of. I look forward to the new products being offered by various Japanese manufacturers…and I was not that impressed this year. No offense intended for them. I think that all aftermarket industries are having a difficult time right now with new emissions regulations (not necessarily the regulations, more the enforcement of laws that have been “overlooked” in the past), and the Japanese are not excluded. The trends I saw were straight forward; what parts can be offered that do not increase the emissions of the vehicles…not much. I saw tons of accessory equipment; wheels, suspension, minor body modifications, after-cat exhausts, etc. and some focus on ECO friendly products. One nice trend I saw was the manufacturers moving to lighter materials such as titanium for exhaust manifolds, turbo manifolds, intercooler piping, & intakes. This means (hopefully) that they are able to better their titanium manufacturing abilities…making a car lighter will make it perform better. This should only bring down the costs of these items if the markets can be competitive enough, this is a good thing for us common folk.

Here is the JDM EVOX Turbo Part # for those that need it.

This trip has been my most diverse indulgence in food while in Japan. I have eaten…fugu (poisonous blow fish), nato (fermented soybean), Katsu (style of breading and frying a protien and eating it with rice that has tea poured over it), Japanese soju (Japanese version of a Korean liquor), jelly fish, shark fin soup, abalone, curry, raw squid, great Indonesian food…a very diverse menu thus far. The fugu has to be a prestige thing, the meat itself is just a white fish and does not have much flavor or texture…at least I did not croke. I am not a fan of ordering any type of shark fin, they way those fins are harvested is downright cruel. The sharks are basically caught, brought up on deck, then the dorsal fins are cut off and the sharks are thrown back into the water…where they drown. Nato is something that I can say I have eaten, nothing I really enjoyed, but I tried. Japanese soju taste as if it aged in barrels…the Korean version is a bit sweater and easier to pound down like they do. Visits to a curry house are a must. These places (and many other business eating establishments) are all about getting it done. Your order consists of what curry you want, how much rice you want, and the level of heat you can tolerate. The food is delivered quickly and piping hot. I personally cannot eat as fast as most locals do, but you have to be respectful about eating quickly so you do not take up a seat as you often see a line of patrons waiting outside. I can usually handle the heat pretty well, but I sure as hell am not going to try the hottest. I have eaten enough of this stuff to know that anything above 7 will eat through paint. I may have also put a hurt on Billy…I don’t think his stomach is accustomed to the heat. We tracked down a great Katsu restaurant in Shinjuku that offered a side of thinly sliced cabbage with a dressing that we super good IMO. I need to figure out a translator so I can order the dressing to enjoy at home.

The show was a great opportunity to get up close and personal with some Japanese race cars. I always find it interesting to observe what others employ to give them a competitive advantage. One thing that was killing me was the fact that just about all R35s appeared to have chromy bling wheels rather than proper lightweight wheels, hopefully this was simply due the the little preparation time they had.

The latest R35 GT500 car appears to have a totally different aero package and it will be interesting to see how this car continues to develop. I am no aero expert, but it was obvious that this car is employing a much different approach to aero than the previous Nissan models.

Where do I sign?Sign me up if the Nissan Dualis comes with the bot.

By far the sexiest car of the show was a IS F “race prototype” that Lexus was showing. I have some shots of the underside that show what the aero was doing and it appears that the car has been run…then very carefully (and beautifully) cleaned up. The car is LHD and looks like it could fit in ALMS, Grand-AM GT (except I don’t think these aero mods are allowed), or even DTM. Regardless, I will follow this car around just so I can absorb some of the sexy that was dripping off the car. The super clean, white Nismo accessorized R34 that Brembo had in their booth was a very close 2nd IMO. The problem is that I would sell one of my children (if I had one) for either car and I would daily drive both of them…which would leave me without a significant other and shot by several of my friends.

PRI 2007

Posted by admin on 14 Jan 2008 | Tagged as: Uncategorized

I have been super busy with work lately, time to get back to the blog. I had the opportunity to attend the PRI show for the second time in four years…bad ass again. This show is primarily a bunch of classes for co-workers and myself, but we get a few hours to attend the show. I will sound like a bit of a geek, but my class schedule kicked ass. Below are some of the classes I attended this year:

  • High Performance Engine Design and Development by Geoff Goddard (former Cosworth Lead Engineer)
  • Combined Video and Data to Improve Performance
  • Class 3, Foundation Of Today’s Race Cams, by Isky Racing Cams
  • Class 4, Improve Your Performance Using In-Car Torque Measurements by ABB
  • Class 5, Combining Video Data to Improve Performance by PI Research
  • Class 6, EFI and Hilborn Fuel Injection by Hilborn Fuel Injection
  • Class 7, Using Video For Driver Coaching & Chassis Development by MoTeC Systems USA
  • Class 8, Springless Valve System by Made For You Products LLC
  • Class 9, Upcoming Developments in Engine Management by MoTeC Systems USA
  • Class 10, Getting The Most Out Of Your Engine Management System by MoTeC Systems USA

By far, this show blows away SEMA if you are a techy guy or gal. No dudes googling over show girls, free classes (classes that actually teach you something), no loud and obnoxious marketing crap, smaller, more focused booths, actual technical people whom you can speak with, and full of products that are engineered to make your vehicle faster. Cameras are not allowed at this show unless you are press, but some one gave me a few (fuzzy) pictures.

TiAL’s Possible New IWG TurboThe V8 and NASCAR industries are super big here, but I still got to see much of what I like with data acquisition companies that are now offering their better products to the public (now they are out of F1), and various companies offering new formula cars or spec racers. By far the best products of the show were all of the newer and much smaller DAS hardware offered by AIM Sports, CDS, and Magnetti Marrelli. TiAL Sport was also displaying another interesting product. Nothing that is in production yet, but they had a turbo with an integral WG. The IWG plumbing is still part of the turbine housing, but it vents to a section of the turbine housing that is kept separate from the turbine exhaust gas flow (outer circle) until the gases mix at the extended turbine outlet. I have always been a fan of an IWG vs. a EWG when it comes to weight and simplicity. I will be a swinger of these turbos if they can perform as well as turbos with EWGs. Very cool idea.

HKS EVO at PRI 2007HKS also had their Time Attack EVO on display at the show. We did our best to look at what they have been up to. The front end has gone over some serious revision since I had seen it last. Ultimately, they have had that car up and running for some time and they have had the opportunity to get tons of track time which is critical IMO. That car and the team that engineers, manages, and operates the vehicle are very accomplished and I look forward to being able to compete against cars of this stature. One last PRI note, I am still waiting for the day that carbon brakes can be afforded by average folks like myself, so get on it! ;)

SEMA 2007, the chrome kicker show.

Posted by admin on 19 Nov 2007 | Tagged as: Uncategorized

SEMA was the usual non-stop work week for me. This happens only once a year so I do what I tell others to do sometimes…deal with it. I find it nice to meet some of our tuners, customer, and vendors in person; meeting face to face is always better. I really only saw two companies making something impressive. One was Cosworth’s intake manifold for the VQ35 engine, an impressive looking piece.

VQ35 Intake Manifold 1 and VQ35 Intake Manifold 2

And the other was a cool gadget. I am usually not a fan of gauges, but this device was super cool IMO. PLX Devices makes a 60mm gauge that picks up data from any OBDII port and allows you to display it on the guage. You can scroll through all of the loggable OBDII data stream variables with a wireless remote, choose a customized display, or even create your own. The below picture kind of sucks, but you get the idea. All automobiles are going to have to monitor everything in a vehicle so they can optimize the performance of the vehicle. They will basically have to do what good hot rodders do with engines and what any race engineer does with the chassis and aerodynamics. I just hope that the driver is not taken out of the equation, some of these newer cars almost drive for you. A smart product would be a DAS that pulls all chassis information from the various sub-systems in a vehicle then uses it to display necessary data for the driver, log parameters, and use algorithms to calculate how to optimize the suspension, chassis, aerodynamics, driver, etc. This is stuff that used to cost tens of thousands of dollars to do. If you start to make this product then you owe me for the idea!

So I took two pictures that pretty much sum up Vegas. Not a place I would want to raise a child, but definitely makes the child in me giggle whenever I am there with good friends and a bunch of money I don’t have to account for.

Only In Vegas Only municipal cross-walk signs which have been purchased by funds comprised of gambling taxes can pay for something like this ;)

Learning something new

Posted by admin on 09 Nov 2007 | Tagged as: Uncategorized

Learning something new is very motivating to me, and it allows me to take a break from the norm. We wanted to display some initial ideas we had like our CFRP (carbon fiber) intercooler end tanks and some carbon fiber piping. If you have ever had the opportunity to work with this stuff it is very similar to fiberglass and if you have never worked with fiberglass then don’t have your first attempt at an FRP be with carbon fiber. The costs can rack up quickly when things don’t work out well and this stuff shows you very clearly where you screwed up :(. Billy, Justin, and I decided to take on the task of making some prototype CF intercooler piping. After a crash coarse in reading material (non of which had any information as how to MFG CF piping) we dove in with two initial ideas, which seemed great at first. Of course, the final prototype was made from an entirely different process which we made up along the way. Regardless, we displayed these product ideas at SEMA and it was good to hear some positive (and negative) feedback from the masses. The end tanks may make it into production, but the process for the piping needs to become much more efficient to be able to offer it for sale. Below is a picture of this work.

Prototype CF piping and I/C end tanks

I have some more information on SEMA that I will try to post up next week…something along the lines of what I thought was impressive, the normal shit that sucked, and of course the debauchery that is Vegas ;)

Hello world, please allow me to introduce myself!

Me llamo Christian James Krahenbuhl (yes, my name is long and it is Swiss if you care to know). First post on my first blog, first of many things this week. I have been working on some composite items…getting things ready for a trade show. The first prototypes came out well so I am excited to see how the next ones turn out. With many things, I feel composite components will get better with repetition. Like much of my life, I learn and teach What Not To Do and this week was no different. ;)
