Тест Датсун Он До: японское недоразумение?
Тест Датсун Он До показал, что разница между этим новым японским автомобилем и Ладой Грантой - в доводке. За доводку Гранты заплатил "Ниссан" и получился Датсун Он До. Недоразумение ли это японское или расчет читать здесь http://automps.ru/2014/11/test-datsun-on-do/

Cylinder Head 205 - Degree DOHC Camshafts
This video is all about establishing your valve timing baseline, and adjusting your camshafts to the manufacturer's spec. It's only ONE of several steps that should be performed when you're assembling your engine on an engine stand. Establishing these conditions with accuracy while your engine installed in the car is a near-impossibility, and the reason why... is demonstrated in this video. There are several challenges to overcome when performing these procedures on a 4gxx series Mitsubishi engine, and they're all defeated here. The cylinder head used in this video is a J1 spec '92 Hyundai Elantra small-combustion chamber head which has had several valve jobs and has been resurfaced multiple times by budget engine remanufacturers who didn't care about quality control, as well as performance shops who do. It has had no less than .040" removed from the head gasket surface, the valves are recessed because of all the valve jobs performed, and at some point when it was cut, it wasn't level. Removing material from the deck surface will change the installed camshaft centerline, and that will change your engine's valve timing events even if all other parts remain the same. I would claim this is a multi-part video except that I've got the videos broken up by topic already, and this one is all about setting your cams to the manufacturer's specification. It is not the end of testing that will be performed with these tools. The basics concerning the process and tool fabrication are covered here. Further discussion on this topic concerning the effects of advancing or retarding camshafts from spec, and for checking your valve clearance will be in the videos that follow. I had to end this video after the manufacturer's spec was achieved to make it easier to digest, and because it would have created a video greater than one hour in length despite the break-neck speeds that things happen here on Jafromobile. Where your cams are set determine how the swept volume of the combustion chamber gets used. The information on the manufacturer's spec sheet is their recommendation for baseline settings that will help you get the most out of those camshafts. Whether or not your engine can operate with those specifications without additional hardware or without causing a catastrophic failure will be expanded upon in Cylinder Head 206. The next video should be used as a companion to this video because establishing the manufacturer's baseline is not the end of the assembly or testing process. It's only half the battle. Should you be lucky enough to find your combination of parts allow your camshafts to fit and requires no additional adjustment after assembly, the steps in this video and in Cylinder Head 206 should still be performed if you are doing the assembly yourself. Failure to inspect these variables may lead to a tuning nightmare once the engine is back in the car, hard starts, or worse... bent valves and damaged wrist pins. Making these tools and performing these steps will give you the peace of mind to know with certainty that your engine is operating safely at its peak performance.





Fairlady Z Build Updates
Today I thought I would update the couple of guys subscribed to my channel with an update on the car. I just had it painted so I thought it was about due for another video. Updates in this video, New Paint in Gloss New flares Ducktail spoiler Headlight covers New badges More updates are still to come. I have bought a new centre console and gear shift boot, and a whole lot more, but for today, take a look at the new gloss Hiroshima Screama. Check out my new online blog for regular photos and news updates. https://www.facebook.com/hiroshimascreama

Datsun 240Z Restoration Project
Slideshow of restoration project for a one-owner 1971 Datsun 240Z. This is a Series 1 car with a build date of 12/70. It has a 1st-gen. BRE "Spook" on the front, used only in 1970 competition. Light cosmetic mods, pure stock drivetrain.





Overhead Cam at 14K RPM
This video shows an operational cutaway of a BMW S1000RR — a 193HP superbike — bumping against its 14,200RPM redline. A cam and valvetrain at 118 cycles per second is an amazing sight (and sound)





CRX SOHC ALL MOTOR 12.7 RUN
Another crx single cam all motor by chapu and taller pancho running 12 seconds at 1/4 mile track. Just two runs on the night, first 13.0 missing 3rd gear with 1.9 in the 60ft. and the second 12.7 with 1.98 60ft. Better Times soon...

600+hp Datsun dyno session
series of Dyno pulls, with a best of 607 hp This was the first Dyno session where my car exceeded 600hp to the wheels. The runs were performed at Motor City Motorsports in Riverview, MI on a Dynojet 248C (yes it was calibrated properly). The backfires at the end of some of the pulls were just from the rev limiter's 8000rpm fuel cut - this introduces unburned oxygen into the Exhaust and burns any previously unburned fuel from the rich mixture prior to hitting the fuel cut. The engine is a stroked Nissan L-series, 3.0 litres with Diamond custom forged pistons and Cunningham rods. the head is an N42 with a fair amount of port and combustion chamber work,- ceramic coatings on the pistons, chambers and ports. Also has a custom cam grind from Elgin. The turbo is a GT42R with a 1.15AR hot side and a 4" Exhaust that exits through twin 3" oval pipes on either side in fron of the rear wheels. Fuel injection is a Electromotive TEC3r, and I did all of the tuning myself. There's a lot more, but that should give an idea as to what's in the car. no Nitrous no water or meth injection 94 octane Sunoco pump gas I've posted some additional details here: http://forums.hybridz.org/showthread.php?t=121857





1972 Datsun 240Z run. (One last good time before I sold it)
Right before I sold it... Clicking noise is a leak in the balancing tube (welded day after this video) Some sloppy shifts due to slack in the rear end and un-adjusted clutch with cracked clutch arm bracket. I loved/love this car! So much fun to drive...
