No rush atm bro we are snowed tf under for the next month or so at least!

@@BoostGumps yeah bro that's good plenty of work but sometimes it feels like a curse! Loving the vids bro

Our trust go-to, the crow 1287

Youre watching one

@@BoostGumps you said stock heads. Do you think with cnc heads and a fast intake manifold you could get 520 hp with a manual and the 1287 cam?

@@user-yx4lt5kz5f ohh my bad, we have made 495whp on the same package with cnc heads on 6L, so yes i think with a fast intake also 515-520 is not out of the question 👌

Hey mate what's your order number? Flick us an email info@onsongperformance.com My apologies, we have had some issues with shipping delays on stock, The above email is the best to get us on, sorry if you have been trying the other email I have just been too busy to monitor both the last 2 weeks

@@BoostGumpsthanks guys appreciate it order number is #1191 and also sent u a email just incase

Thx guys order number is #1191 also sent u guys a email regarding it.

Definitely DOD, if manual it wont be activated electronically at all. But will still have all the DOD hardware phsically in the engine.

This same combo in a car would probably be 350 whp. Landcruiser driveline is heavy though. Lots of rotating mass in the big gearbox, transfer case, big diff and big heaver wheels and tyres. All of which tax lots of power.

@@BoostGumps yeah that makes sense. I have an old 1hz cruiser that i turbod. Before the turbo it made 60whp and the engine is rated at 130. 50% horsepower tax is crazy but probably wouldnt be hard on a slug engine lol. If the 80 & Ls combo only tax 50hp out of 350 then thats not too bad then i suppose

I could imagine it's a little weapon! Often with wiring thats the best move. Just start from scratch!

Looks like a cut down swb sj70 cab with a lengthened chassis.

Yeh definitely true. What you are essentially doing with 2step, is dumping excess fuel into the cylinder and delaying the ignition event excessively. The idea is to ignite that fuel once its already in the exhaust port, causing an explosion/rapid expansion directly in the exhaust. So having this happen can certainly blow out gaskets and wreck manifolds if not done correctly. Another risk is having this pop the exhaust valve back off the seat and opening it into a piston, so make sure you have decent valve springs!

@@BoostGumps thanks for the explanation. You guys really know your stuff, I love watching your videos. Especially dyno tuning vids, they're my favourite :)

That's overrated you learn more from problems😊

I dont disagree but i rekn these fellas have had plenty of learning opportunities in recent years so its nice to see them have a win once in a while is all i meant

Can confirm it is an absolute weapon off-road.

I should probably make a video explaining this in depth a bit better. What I should have explained is that the dynamic compression is most affected by the timing of the intake valve closing in relation to the induction/compression stroke. The later the intake closes, the more dynamic compression you will bleed. This doesnt always directly correlate with the lobe sepperation angle, but more accurately correlates with the intake lobe centreline and intake duration. By the time you open these engines up and allow them to breathe properly, plus a half decent cam, you generally will find in most cases that they lack enough compression and are not knock limited. This isn't exclusively the 6L, it applies to all stock bottom LS engine combos in our experience. Compression and Vacuum don't necessarily correlate either. Generally speaking, cams with more valve overlap create less vacuum as it slows air speed quite a bit at idle. Having very little vacuum can make them hard to tune, because in a speed density situation where we are tuning based on manifold pressure (vacuum) it shorten's up our window for tuning and we lose lots of resolution when compared to a cam that creates more vacuum. This isn't a problem for wide open throttle, but for transient and low throttle and cruise tuning, hence cams with very tight lobe sepperation angles are generally not used for street applications. (In EFI cars like LS's, you will find Carb'd cars will use much tighter LSA's, things like SBC and Carby LS combos need a tighter LSA cam) So yeh, although cam and valve events do affect both dynamic compression and vacuum, they do it in different ways which arent necessary linked.

Cheers mate! We have had a horrendous run the last 3 months, but keen to get your Ram in soon and have a play!

@@BoostGumps oh true bro that's no good hopefully you guys are at the ass end of that! Yeah bro I'm keen to send the ram in when you guys have time! The SS still gets me going every time I drive it by far my favourite car I have ever owned!

Hey mate, do you mean as in a video of dialling the cam in? Just to show how to do it? Or just to demonstrate at what degree the cam was installed?

That sounds like a good idea! Once we have caught back up on the work we have up to our eyeballs, I would like to start making more vids as such, and other requested content that viewers wish to see

109 LSA is the perfect cam for a 6.0 according to DV. But, it's hard to find a .600" lift cam on a 109 to take advantage of the high flowing LS3 heads. So, by his data going narrower will be as good or better. I'm running a Cam Motion Little Chopper in my L77. It's on a 108 LSA.

Im not farmiliar with DV's work, but can add that from all our understanding and flow data that I have analysed from rectangle port heads, that I wouldn't necessarily use 600 lift as a minimum. CFM rarely continues after 580 from what I have seen. The lobe profile will make a bigger difference than the overall lift, the faster the valve gets to that 300 ish lift the better.

@@BoostGumps Thanks for the reply. Yes, the flow in the rec port heads level off after .580" or so (diminishing returns after that point). I wanted to make sure to go past that because there is some data suggesting that more lift (even when it doesn't look like it's needed) will produce more power. Eric Weingartner shows some data on his YT page that correlates the power increase from a few years ago. Does the power brakes work good on this car?
