RB26 Adjustable Cam Gears Work - THE END! Kelford Drop-In Camshaft Test in R33 GT-R N1

[@Monstero5o]

Getting happy over 400awhp is a blast to the past of the early 2000's. How i wish it was it was still the early 2000's.

[@R-Tuned-Performance]

Hanging with you guys is NEVER a dull time! This series totally reminds me of all the late nights modding cars and talking trash with the boys! Can’t wait to catch up at GTR Fest.

[@ClaytonYatescarenthusiast]

That's probably my favorite video from motive. This and the aero video series

[@sircefiro]

All the old budget supercar killer vids are awesome

[@Master_Psyper]

Andrew, it’s midnight and I have to be up at 4am😭😴, oh well, time to learn about adjustable cam gears and drop in can shafts🙃

[@MotiveVideo]

We finished filming that night at 2am so it's appropriate.

[@PHATT_TV]

@@MotiveVideoAwesome info mate. Question= I’m at 700whp on Hks 264 cams, at what power level should I bump up to 280/292’s etc???

[@zac2384]

@@PHATT_TV I'd say if your torque curve starts to dive down, then you'd might want to consider the next step up. 280/292 might be too much, but it would definitely sound cool.

[@PHATT_TV]

@@zac2384 thanks! My torque curve find atm, but I’m going (currently 700whp) to 1’000+ soon. You think 272 or go straight to 280 for 1’000 to 12’000 max??

[@markc1456]

@@PHATT_TV you should already be running atleast 272's! i made good power on gsc 268s in my Evo8mr before going 274's! picked up gains everywhere except spool but loss was hardly noticeable

[@kanenstuff]

In my 180SX with a CA18DET the half moon for the CAS was worn. I changed the exhaust cam to the inlet side and replaced the exhaust cam with a fresher one and slapped some adjustable cam gears and I got 50hp on the dyno.

[@Stuntlight97]

What did you end up with for cam timings? I did the same swap on my CA but with stock gears and the intake advanced one tooth which should be quite close to optimal

[@kanenstuff]

@@Stuntlight97 I can't remember I think it was 4 degrees on the Inlet. This was back around 2007, I still have my 180SX but has sat in the parents shed for 10yrs now as I work in Asia.

[@danielwitham1791]

​​@@pheonixfps9248agree As someone who's gone stock to 800+ with 2 GTRs (31 &: 34). I also find just over 400hp is where the fun starts. 500hp is really fun and where the truly aggressive acceleration really begins. After 600-700ish it's hard to use on the street and just mind meltingly fast!!

[@sircefiro]

Great vid, the old budget supercar killer vids are still gold too, surprisingly there's not many back to back kelford cam vids like this, seem to be a bit better than the tomei but tomei still aren't bad for most basic builds, the 25 doesn't benefit as much from gears but the 26 def does

[@manitoublack]

in what shouldn't be news to anyone. Optimising cam timing is of measurable benefit...

[@AdmissionGaming]

You said this too fast for me to understand can you explain it properly?

[@davidcathro3510]

I read on a forum that my brothers cousins uncle dyno in Florida we lost power with cam gears.

[@IsentropeMachzahl]

@@AdmissionGaming Cam timing (or valve timing) affects how well the engine can "breathe" - how well the exhaust gases are exchanged with fresh gas mixture. This is known as volumetric efficiency (VE). The more air you get into the cylinder, the more fuel you can add (if targeting the same AFR or lambda). That means there is more energy in the charge in the cylinder. At the same timing (degrees before top dead center when spark occurs), this leads to higher pressure inside the cylinder. The higher the pressure, the greater the force on the piston and the higher the torque on the crank. Power is just torque times RPM and a constant. Hence, improved valve timing increases power.

[@AmirPomen]

​@@davidcathro3510having cam gear is 1thing... Knowing how to adjust them to suits your engine need for optimum setting is another story.. " Look up "camshaft dialling"

[@Tom-lf8hx]

The GOAT spitting facts again ❤ when will people learn 🤷‍♂️🤣🤦‍♂️

[@tturi2]

thats a great insight on the 4wd system on the r33 what about v cam? vs adjustable cam gears?

[@Akatsukihi]

Would be interesting to see V CAM does on a stock motor. My R33 gtr on 12psi on stock ceramic , with prp coil , NZ trigger kit, Dahtone IAT sensor, 800cc injector and LINK g4x does 340hp ATW. Vcam is next on my list to build a responsive street car

[@sircefiro]

V cam definitely helps but is considerably more money than just gears

[@Akatsukihi]

@@sircefiro But also bringing the RB slightly closer to modern tech

[@student_driver_club]

[@SpecificationR]

The only jeedeeahh on Motive vids without a custom plate. Amazing

[@gorans7518]

4wd -rwd. Not trying to be cheeky, this is what I do and iv got a switch too. Iv got a 260rs and the factory way to make it rwd for towing is by removing the wire (green clip on mine) when the car is off, behind the drivers kick panel. Start it up and you should see the 4wd dash light flick on then pump the brake 5-6 times then the light should hold steady and you can hear it depressurizing. Put a switch so you can do it easier, but the car needs to switched off when ever doing it on or off.

[@manage13]

Well done Andrew and Herman

[@Bootsos90]

Sooo this is what it would of been like in the 70-80s when 400hp was like 1500 nowadays haha. Impressive numbers fellas

I wonder if playing with cam timing will gain me anything on my turbo high compression 5efe. Its slave cam so it only has 1 cam gear (on the exhaust) so it would be a global change...however I could maybe change the relative position of where the intake cam meshes to the exhaust cam

[@internetusername9593]

If you were concerned about that you could use a couple trolley jacks in addition to jack stands to put a bit of pre-load on the suspension arms.

[@jobijon80]

The whole video is advancing intake vs std timing...but std timing hasn't been degreed. It would be interesting to know what's the difference compared to theoretical setup. Maybe those 2 degrees just allow to come back to supposed OE setting? I personnaly degreed my timing when rebuilding my engine and aimed for std HKS setup. Had to move the pulleys few degrees...

[@MotiveVideo]

The car started at OE setting. We've done this many many times.

[@MotiveVideo]

Best advice is save your money and buy a DET

[@jesseyoung4295]

With a n/a engine the biggest limiting factor is air intake. A tumed intake can get a little above atmospheric pressure, but otherwise your engine is only capable of pumping roughly 2 liters of air in, which can only burn so much fuel. You'd be lucky to make more than 200 hp.

[@beccabriansarubbi9413]

From some of the info I've seen, you only get the exhaust cam gear due to the VCT on the intake. What the power output/advantages are, that is to be determined. Only a couple weeks away of receiving delivery of mine and I will be putting the cam gear on with a PRP trigger kit and will know what the deal is

[@flamintasty]
