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

In this episode of Motive Garage, presented by Sparesbox, we install PRP adjustable cam gears into the R33 Skyline GT-R N1 and prove, once again, how essential they are.
We also test some Kelford Drop-In Camshafts for RB26 with some incredible results!

400hp...yhe funs only just starting on a stock Skyline GTR....

[@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!!

[@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.

[@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.

[@ChrisOstreicher]

@@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"

[@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.

[@Tom-lf8hx]

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

[@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.

[@crd-nz_001]

An old term given to times like this is "polishing the sculpture," and she polished up very nicely.

[@clarenceperkins3115]

By far the most exciting dyno tuning video I’ve seen. Top notch info can’t wait to apply this to my Rb 🤙🏽

[@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

[@Understeerking]

Another banger video. To be so knowledgeable, you two must make everything easy to understand.

[@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

Forget RB. You need adjustable cam gears on any serious build. IT IS the only way to optimize Your cam timing.

all RB’s should have atleast a 260 drop in cam. My 25 neo loves its type B 260 poncam

that as it is would be an amazing street car.

[@TheLabLimited]

I wish "dropping in" camshafts was this easy with a VQ ha ha!!

[@garage79r]

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

[@evanpoulos6047]

Forgive me if I have missed this detail, but what size fuel pump, quantity of fuel pumps, size of injector and fuel pressure regulator were used to make this power? Great content btw. Cheers.

[@GORZ_YOUTUBE]

This is the most existing 400hp I’ve seen on internet 😂😂

[@danielsmith9682]

Only thing that sucks about just jacking the front up is the cv boots don't like it and you have to get new ones and it makes a mess 😐

[@mickanon5607]

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.

[@robbo17586]

[@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.

[@jobijon80]

@@MotiveVideo My point was "does OE on pulleys really give the OE supposed setting"

I actually have a question which I can't see anyone answer, Cam Gears vs RB25 NEO VCT. I always get answers like no don't do it it's a waste or I get like Yea it's worth it cause you get way more midrange

[@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.

I always wonder if you guys test the HKS V-Cam Pro setup? Would be interesting to see the true gains vs stock vs the PRP adjustable cam gears.

[@dillon_r_hansen]

more mid range for sure. wider available cam advance range to optimize air flow as engine RPM changes instead of finding a fixed advance that suits the entire rev range.

[@linchester8464]

@@dillon_r_hansen other than the Best Motoring/Hot Version DVD covering the HKS demo car having the V-Cam and how the Drift King can make the R34 drift and commenting how the car suddenly got mid range torque which allows him to do that stunt. Very little info on the system. All i know is that the system is borrowed from the Subaru's STi AVCS system on the EJ platform.

[@dillon_r_hansen]

@@linchester8464 variable cam timing offers the same benefits to all engines that use it. I'm extremely familiar with the STI AVCS gears. I have been rebuilding and servicing them for a decade. The advantage is you can now play with 30 degrees of cam timing instead of the small single digit fixed adjustments from adjustable gears. Go watch a video on VTC adjustment for an N/A k series. it makes a dramatic difference in low end response and midrange torque. The effect is so strong because of the very efficient high flowing heads on k series engines. AVCS, VVTi, VTC, HKS V-Cam are all the same system generally speaking. adjustable cam gears controlled by an oil solenoid and directed oil pressure within the cam gear cavities. If your engine has it you should run it.

[@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.
