So I'll let out a little secret.  I'm a HUGE car guy.  Anything with wheels = love. 

Any other car guys here?  ::)

You bet!  Thanks for those.
Heading for Reno and Hot August Nights in a couple of days.  A great experience, if you've never done it.  Am going to the Barrett-Jackson auction on Thursday just to look.  It'll be televised on Speed Channel Thurs thru Sat.

I hadn't seen this video before tonight, but your posting caused me to do a YouTube search for a Full Blown Motorsports Nissan GT-R. The first one that came up happened to be a video highlighting the new 1500+ hp intercooler I designed for the GT-R.

You can first see my intercooler at about 50 seconds and several times throughout the video after that. Then the video concludes with several passes on the 4-wheel drive dyno. That itty bitty 6 cylinder engine cranked out over 1000 hp at the wheels!!!!! If I read the screen correctly, it made over 1100 hp.

Edit: After looking at the video closer I noticed that only the rear wheels were turning. I didn't know you could shut down the AWD. John, the owner of the shop, has a 4wd dyno specifically for these cars.

This isn't your run of the mill grocery-getter. It's a low-cost super car that matches the $500k super cars. Off the showroom floor, it will do 194 mph with 575 hp AWD. It has an incredible "launch control" where the computer monitors the road and all 4 wheels to rocket this off the line at an amazing rate. (Search for Top Gear UK...they have featured the GT-R several times.)



The high volume intercooler uses an off-the-shelf core, but I designed the top and bottom caps specifically to fit the tight confines of the GT-R engine bay. The flowing design is one of the more complex SolidWorks challenges I have worked through. Each cap is CNC machined from a solid aluminum billet, and then welded to the core. Because this rather unique 6 cylinder engine is literally like two 3 cylinder engines side by side, each bank has their own turbo and their own intake throttle body. So it is really two intercoolers side-by-side, but with a deliberate bleed-through between them to assist in balancing the pressure between the twin turbos.

You can see the actual intercooler in the video, but here is the CGI image from SolidWorks. Oh, by the way, this is the same machine shop that fabricates the parts for my SCG-10 guides, and even some of Ron Wenner's products. That's how I came to know this legendary automotive super-tuner to design a bunch of car parts for him.

Here's another video of John (LJ) doing a dyno run with a GT-R. This was from last year so it is before I designed the intercooler. This one only makes 700 hp.....as if that is trivial.  [eek] But in this one, you can clearly see that the car/dyno is AWD.

Come to think of it, as memory serves me, something broke on the white car, and that could be why it was only a 2WD dyno run. Me and my son Tanner were supposed to go down to the shop to watch that dyno run, but something on the car broke, so we never got to see it personally.  



We've done quite a few projects together. Here is an intake manifold for a Honda S2000 that we recently wrapped up. This is a cast aluminum intake manifold for the S2000, 4 cylinder engine. It was one of the first projects we started, but took this long to get finalized and realized in actual product. This was by far the most complex design I have ever completed.

In order to get 850 hp out of this little 4 cylinder engine, John was pushing well over 35 psi into the factory manifold. So we designed a new manifold to give us similar volume at lower pressure. I don't remember the numbers, but I think this is like 4x the volume of the factory plenum, and the runners are massively wide and super short. Everything was designed to flow massive amounts of air with the least resistance.

Yes, you may notice that the cardboard box has Festool green color. It is! But I can't tell you what was originally in that box.

OOH Barrett-Jackson auction!!  Every once in awhile I'll catch bits and pieces on TV.  Someday (hopefully soon, with fingers crossed), I'll dabble into the American classics.  It's a rite of passage to me -- wouldn't be able to rightfully call myself an honest gearhead without. 

Have fun mate!  Don't sell the house!

Mr. Christopherson, sir -- is there anything you are not awesome at?   [blink]

In a distant parallel universe I very briefly lived as an Authorized GT-R Sales Specialist, selling our store's first one.  In a previous life before that, I floated in and out of the automotive aftermarket and somehow convinced the right people that I was half decent at suspension design and setup, and somehow ended up helping a couple Honda Challenge / USTCC race cars move up a few places (still no podium though... poop)

That intercooler is one beautiful piece of work.  Here's a t-shirt (that you'll have to wait a bit for it's next production run) that you may enjoy.  That VR38DETT is really something that still boggles the mind -- I wasn't much of an adopter in the beginning.  The RB26DETT just made more mechanical sense to me in three words -- cast iron block.  Maybe I'm even more old fashioned than I give myself credit for.  But hey, fast is fast, and I think it's still fair to say R35 aftermarket support is still nascent at best, so still many many more records to shatter in years to come!

Last I'm updated with is this - the AMS GT-R


What really took my breathe away though, was your S2000 intake manifold.  I'm a Honda boy (gotta stay true to my roots!)  Sure would love to see that thing on a flow bench and/or CFD images.  I'm still saving up for my own S2000, hopefully by early next year? *fingerscrossed.  My NASA instructor is kind enough to hold his unicorn, a 2004 AP2 with 12,000 miles on the clock, awaiting my purchase.  Eventually I hope to stash away a NSX to keep forever and ever.



I shall respectfully not inquire on said original content of said Festool box  [big grin]

Great thread and nice work Rick , I am a tool and die maker by trade so I can appreciate every thing that went into your design. I don't think I am mature enough yet for a car like the GTR so for now I will have to stick with my 2007 Audi RS4. That being said though feel free to design and build any performance enhancers for my ride and I will gladly test them out for you. [smile]
 We just got back from a weekend in Oswego New York watching the super modifieds. I believe this track is one of the best kept secrets of auto racing. For a mere $20 you can enjoy a night of 800+ HP, 1800 pound cars running a 5/8 oval track that results in some very exciting racing.

Nice man!  If you're ever out here in San Francisco, do please check out Sonoma Racway (previously Infineon Raceway), and of course home of the corkscrew, good ol' .  <-- Click that GoogleMaps link and switch to StreetView to do some laps alongside ALMS cars ;)

Any track days out in the RS4?

Yes I have done a few track days at Canadian Tire Motorsport Park http://www.canadiantiremotorsportpark.com/ It is an absolute blast and adrenaline rush . CT Motorsport park is actually the fastest track in North America and the third fastest track in the world. We will be camping there this weekend for the Canadian superbike races.
I have also done MANY laps at Laguna Seca but they were all on my PS3. [smile]

Today, a post on SAFETY!

You probably all know what it's like trying to tell a friend or family member of, well, better ways to drive.  Usually doesn't go too well.  Alas, I still find it to be our civil duty, as car guys, to help keep our loved ones safe.  So here's a (G)oldie from the past, about carrying cargo in vehicles.  Be it your work van with Systainers, or your family car with a child seat, please take 10-minutes to watch this clip.

Always use your cargo net and tiedowns.  Try your best to reduce loose items in the passenger cabin area.

Start at 11:18 to skip right to the crash testing bit.

Here's a video that features my car.  I'm the red car in front of the red #8 car at the start.  I'm starting 2nd and the camera car is 4th.  If you make it past 15:00 or so, the red car in position 5 makes an appearance running with the orange car that starts first.  Orange car is fast, but was making sure some problems he was having were good before coming up to speed.

It took the camera car a few laps to get his legs, but he started to open it up about halfway in. Well, sort of. His car was faster than the others, but he just wasn't using it. He held a reasonably good line around the track, but had poor throttle management.

The biggest comment I have for this guy is that "if you're not hard on the brakes, you should be hard on the throttle!!". He had a habit of having the clutch pulled in before the corner, but still had his right foot on the throttle enough to tickle the throttle with the clutch pulled in. Why would he do this? This wasn't a downshift. He was tickling the throttle before he moved his foot to the brake!

You should never be able to hear a downshift. It should only happen during braking, and only to prepare the car for going back to hard throttle.

He also had a habit of holding his up-shift on the straights. It was like he was hesitant to go into top gear. It doesn't matter whether you hit the next gear for 1-second before jamming on the brakes, you still go to that gear. 

It took him a while to realize that he could hammer it through the high-bank concrete turn, but even then he was lifting quite a bit. You have to lift a little entering it because it isn't a smooth transition, but once in the bank, that's where it is a blast to totally hammer it and feel the G's push you into the seat.

He also had a habit of braking into the hairpin too late and overshooting the apex. He was still braking by the time he got to the outside line. A little bit more of that and he'd be in the grass.

His car appeared to be pretty fast with the way he could easily overtake several of them on that one corner at different times. (Appeared to be his favorite corner.) He could actually be pretty good with a little better throttle management.

I'm almost scared to post my videos now... but through humility is the only way to grow... so here we go!


This was probably the last video / last track day I did at Sonoma Raceway (previously Infineon Raceway).  I'm running NASA HPDE Group 1+2, so naturally, all beginners.  Poor Integra has blown a head gasket since then and I haven't gotten around to fixing it  [crying]





My Integra's first video upon first stage build completion!  A little autocross at Oakland Coliseum!


So you'll probably notice that the car is called "Circuit-Sports Integra".  Circuit-Sports is a small suspension specialist company which my friend owns, with emphasis on Nissans.  He wanted to branch into the Honda market, and I was lucky enough to hoodwink him into believing that I had an idea of what I was canoodling about -- thus the suspension system you see here is prototyped, and still on the car today!  

Project DB8 Day 1
- Stage 1 build's emphasis was all on suspension.  All rear suspension bushings are replaced with spherical bearings, and starting from rear trailing arm bushing forward, polyurethane.  Monotube dampers, F:10kg, R:8kg.



Project DB8 (aka NinjaCat) - Stage 2
- Stage 2 saw minor weight reduction, and minor power increase by cams, exhaust system, and engine tune.

Naahh, no worries. That "drag-your-nose-across-the-asphalt" point of view of the camera was pretty cool!!!!  [scared] [scared] That was fun to watch.  [cool] [cool]

I do have the same comment though. You should never hear a downshift, because it means you are using the engine to slow the car instead of the brakes. If you used the brakes, you could hold power for a couple more seconds before hitting the brakes. That would be enough to put you right on the tail of the car ahead of you and possibly power out of the corner ahead of them.

You could also hold a tighter line through the corners. You've heard the line in the Dukes of Hazard theme song, "....straightening the curves...", right? Enter wide and aim for the tight apex, and then exit as smooth as you can with full power. The straighter you can make the curves, the faster you can take them. Your inside tire was a little too far away from the apex. Your entry can be a little jagged because you're on 4-wheel brake, but your exit should be a smooth curve because you are on full 2-wheel power.

By the way, if the driver ahead of you is using the engine to slow the car, he's going to have to take a wide entry into the corner and a wide exit. When you come in with hard brakes, you can take a short entry, closer apex, and then a tighter inside angle coming out of the corner. That is the perfect time to make a pass leading into a straightaway. The tighter entry can get back on the power sooner and have the shorter line on the exit.

This wasn't a downshift. He was tickling the throttle before he moved his foot to the brake!

You should never be able to hear a downshift. It should only happen during braking, and only to prepare the car for going back to hard throttle.


He definitely held back on the first few laps to film his father and I (his father is in #8).  His car is definitely more powerful than the others.  He's a 1.8l prepped for SM, the 3 red cars are 1.6l prepped for SSM.  I think the orange car is a SSM also, but I don't remember and don't know the guy.
I partially agree with your throttle assessments.  His braking isn't his strong suit.  In his defense, that is a funky track.  It is severely crowned for drainage all the way around and doesn't have the nicest/smoothest pavement.  Also, there are at least two braking zones where there is a small rise followed by a small drop before entry.  Need to get most of the braking done during the rise as there is little grip over the crest and down into the entry.  The wide angle camera really hides that.

He also had a habit of holding his up-shift on the straights. It was like he was hesitant to go into top gear. It doesn't matter whether you hit the next gear for 1-second before jamming on the brakes, you still go to that gear.  

This track and stock Miata gearing don't get along well.  If you do shift at the end of a couple of the short straights that put you right near red line you will lose a half a car length.  Miatas rev up around 7500RPM.  Best bet on a straight is to shift a little lower than that as power starts to drop off over 6700 or so, but the shift itself isn't worth it for the few seconds you're falling off the power band.

It took him a while to realize that he could hammer it through the high-bank concrete turn, but even then he was lifting quite a bit. You have to lift a little entering it because it isn't a smooth transition, but once in the bank, that's where it is a blast to totally hammer it and feel the G's push you into the seat.

The carousel is nasty.  We all pretty much launch into it near the speed we'll go around it, no smooth transitions there we're catching air.  But, it's bumpy and will spit you out if you try to go full throttle through it.  About 2/3 of the way around it smooths out and you can hammer it and get launched out.

He also had a habit of braking into the hairpin too late and overshooting the apex. He was still braking by the time he got to the outside line. A little bit more of that and he'd be in the grass.

Actually not a bad line through that turn.  It reminds me of a motocross when you get a bunch of cars going into it.  Some going deep, others tight, and all coming out about the same.  It's super tight with crazy off camber and the exit is the inside of the track onto the really long straight that follows.  Both left's that follow are full throttle if you setup the hairpin correctly, so it's really about the exit speed.  The lines that bigger cars, like vettes, have to take through there is almost comical watching on video.  There's just not much room to get the car fully turned and wind up pinned to the inside of the track on exit so you don't have to lift on little bend.  I don't go quite as deep in as I rotate the car more under brakes, but his way works.

His car appeared to be pretty fast with the way he could easily overtake several of them on that one corner at different times. (Appeared to be his favorite corner.) He could actually be pretty good with a little better throttle management.

I agree, a little more experience and he's going to be quite quick.  He has no fear and has improved quickly.

Enjoyable start to a Monday morning yea?

Had a bunch of car ads hanging in my room as a kid, mostly Ferrari, the then new high tech C4 vette, and trans am.  Only one I had on the wall that made the list was the MG ad, also the only ad with a car I really had no interest in.
