Just messing around for a couple minutes in the mega.

also got a trials dirtbike bike a few months ago.

I rode trials 10 years ago in the STRA Sportsman and Advanced class. I kind of miss it to be honest. Maybe one day I'll get back in it. I had the 3rd 4 stroke Montesa Cota 4RT in the US. It was cool to be around trials when the 4T hit the scene. I was on a gas gas 280 w stroke before that.

I think the new 4t are pretty damn nice. The best trials rider is on a montesa 4t. I got a sherco 300, traded my pos ktm in on it.

Ya man trials is a lot of fun. I definitely enjoy how challenging it can be.

What charger did you end up going with?

S464 Borg Warner. I didn't want to get too carried away. It's been a reliable truck. Spools pretty well on stock fuel.

Cross training on a trials bike will make you better at everything on 2 wheels. I picked up considerable speed in the woods from riding trials bikes for 4 years. The regional series I competed in usually had 50-100 competitors per event and it was the same people every time. My uncle was a minder for a US National pro rider at the time so I was very lucky to be able to spend time around people that were insanely good at trials. They were sponsored by Montessa from 03-08 I think then they switched to Gas Gas.

Are you running stock nozzles too? You can run a 50hp nozzle and still hold 26K psi in the rail without issue. Anything bigger than that would need some pump work done.

464 is a touch big for stock fuel but not out of the ballpark by any means.

Are you running with a shim or plug in your rail now?

I shimmed it, how about you? Yea stock nozzles, fuel system is untouched, just got a lift pump fass 150 titanium for better filtration.

I got headstuds, mcc tuning with custom tune and overdrive, built auto, had a water meth kit, but took it off so I can fit 3 dirtbikes in the truck better lol.

On my next truck I might go for more HP, but I'm at a 180,000 kms now, want the truck to last to at least 300,000km.

I tried mine shimmed for a while in the wife's truck but it routinely sees 28-30k psi in the rail with twin cp3's so I ended up making my own bypass. It's kind of ugly but it works and releases at just under 30k. I did have it plugged for a while but that was awful and I was overloading injectors.

If you have studs and a halfways decent transmission I wouldn't get excited about the longevity. You'll be fine. I don't think EGT's will be an issue either for that setup. If they are, just add the water-meth back in and run it.

With that charger and stock fueling you might hit 575ish on kill so you're really not stressing anything at that point. Some Spicer u-joints would be the last thing I would put in for peace of mind.

To give you an idea, the truck my wife stole from me is a '14 with a de-stroked 6.7L (6.7L block, 5.9 crank, and custom rods ~6.4L) big twins, lots of fuel, and all of the supporting pieces to hold it together. That motor made 1040 on fuel and 1166 on spray. That's running through a burnt out 4speed 47RE I had leftover from a workstock pulling truck. Loose bands and all and she's got almost 35k miles on that setup. The daily tune sits right around 790hp and 1500ish ft lbs on a cold day. If she hasn't torched that old 47RE with that power, her driving style, and 37's than either i'm the luckiest guy alive or you'll be safe.

Since I swapped that turbo in and got custom tuning I haven't even been a little bit concerned with egts. Before just the hot h and s tune man she smoked and ran hot. Haha 790 is ridiculous for a daily, that thing must rip for a big Diesel, I know mine moves pretty quick. I got 35s right now, but my set is done. Going back to 37s.

Yea I usually just say my truck is 550hp, safe bet haven't actually dynod . It has some beefy front end parts. Carli ball joints, torsion bar, 2.5 Pintop kit, Spicer joints and front axle truss. Mag hytec tranny, diff covers etc...
