Yeah Smokey Yunick used the spintron decades ago. He new that things like valve springs work differently at rpm’s. It’s why we use different spring diameters, different spring material. Maybe One diameter coil has issues at a certain rpm, then Al the other diameter spring has a harmonic frequency at another rpm, then they can help cancel each other out. Science is really cool.!!!
So cool. At first, I was thinking - no headers, balancer, intake, etc - what the heck? Then I watched the video. I'm an old gearhead, and not a tech geek. But this stuff is amazing. GREAT video!!! And new subscriber!
Thank you all for the testing/development and sharing it with us. I’m building an ls/lt hybrid and I’m thinking about a custom ground camshaft… 6.0 GEN4 with 2021 Silverado 6.2 LT heads. 😅 currently only BTR has a camshaft.
This is going on a SBE. 9000 is asking a lot long term. We have 30 engine dyno pulls so far on it up to 8600 RPM. This combo isn’t limited to sbe stuff, or na stuff. It is available for all LT applications.
Just want to say my 5.3 L83 dogs stock and modified NA LS out 😂 I’m glad I did it the hard way now…. Different plus has some balls LT genV is the way to go 5.3 and 6.2. To be honest the only lightly modified car to beat me has been a 6.2 LT. Look through my channel and you can see the race for yourself. Glad I seen this video. Back to the drawing board 😂
There really isn't alot of difference in them. The compression ratio and vvt helps to flatten the tq. If your lt is just out right dogging a ls....then someone fucked their ls up
@@HioSSilver1999 I don’t know my friend but maybe I just have a freak of nature or something but I’ve race a cammed 5th gen camaro 6.0 at the track and kicked his ass my brother owns a stock 14 camaro SS 6.2 kick his like it’s nothing, I’ve raced a C6 on the highway and made him exit 🤣 392 scat too… and to make that even worse i have 22” wheels on my camaro…🤷🏾♂️ I just now like yesterday put it on E85 and I have to get some transmission work but going to bolt on a LT2 intake and a bigger throttle body so I should be neck and neck with the LT1 next year…
@@J2A61 hell we beat cammed 5gens with just a bolt on 5gen....cams don't mean shit most of the time. We went 11.5@120 with a bolt on 5gen. Then did a c6 and went 10.5@132. My own bolt on ls6 went 10.7@130ish. The people you're racing don't know wtf they're doing if your l83 camaro is within 3 busses.....or you have something going on you're not telling. Like a gutted car, power adder or massive gear in a short race. Apples to apples or it doesn't really mean much.....definitely not worth bragging about.
Has anyone run just the short block? Without a valve train? Just wonder if there is a limit to rotational mass, or imbalance, wonder at what rpm limit the rotating assembly has issues? Just a thought.
Isn't there less stress on the crankshaft and rods spinning from an outside source vs the combustion process putting more stress on the rods and crankshaft at the same rpm?
