Its hard to tell with out testing its with a strain gauge or alot of Cad work. but it should make a huge different just from a design point. Mech engineer though here

I am saying What makes it that much stronger than a main girdle? it doesn't look like new technology to me. my girdle fit very snug to the edge of the block which i would think would hold more pressure then some oil pan bolts.

maybe your not on the same page as me. look up ls1 main girdle on google. look at how on several points it touches the block for a couple inches. i would think the block would have more structural support for keeping the caps from wandering side to side than the oil pan bolts. and as far as the caps lifting the bolts would provide all the hold you would need there.
Its cuts into the block and the bolts just go though it locking the block and oil pan the mains and everything together. Just cause a part touches another part doesnt mean it will keep anything from moving when we are talking a few thousands of a inch. Does it help yes
Keys cut into a part then bolted makes different parts acted as one.
When we get into the limits of rpms and hp bolts are not always the weak points. The threads the bolts go into could be. The whole block where the bolts tie into may flex.

But what i am saying is the oil pan gonna make any difference? i doubt it. like seriously a main girdle already ties the main caps together. so how is this like a new revalation? the center of the block is already tied together from distortion. I would put a steak dinner on it that the oil pan bolts are not gonna put much structural integrity into the equation!

snd the girdle touching the edge of the block also acts as a key! WHEN PARTS TOUCH EACHOTHER THEY ALSO ACT AS ONE PART!!! I understand what your saying, but from a design point it probably doesnt matter! i doubt you will exceed the strength of a 4140 block girdle without pushing the limits of the block! overkill for sure. its like the building a frame out of 1/4 inch steel. just doesn't need to be done.

with arp studs and a regular girdle will be enough for most street cars or most race cars 1100hp and under. i think this girdle is meant more for a little higher hp engines. seems to look like the oil pan bolts are just a back up support strength for the main caps. but leads me to wonder how the twisting of the block will effect the oil pan.
i will still stick with the original girdle only b/c i dont want to spend $600 more on machine work when i dont really need it

But i guess changing the design a bit could get someone around this guy's patents

I got a buddy pushing 1500 hp on a alum block. Im at 800rwhp on my alum. My new alum block im hoping for at least 1600 hp
The oil pan bolts are not for stopping flex as if the crank is being pushed out as much as for stopping side to side movement of the mains.
Its not going to cause any leaking issues twisting of the block will not affect the oil pan. When a block heats up it twist and grows so it will acted just like it always does.
and for the note of tinys bolts not doing much looking up the size of 6-48 bolts(1/8 the size of oil pan bolt) . They are used on rifles. that take 20 neg Gs of force with fired from a 50 cal
This is going off. lets leave this at its a very nicely designed part

well i guess i don't need to explain anything since you guys know everything,i guess all my modeling and FEA data are lying to me,since you guys can look at a picture and tell me it works no better than any other.The girdle does not rely on fricton or the oil pan bolts to do it's job,it mechanically locks the main caps and the block together-you can't see everything in a picture.This is not for everyone-i designed this for high hp engines-1500+ hp.And i didn't change anything to get around a patent-i made a whole new piece for a stronger design.
I have seen the part and have one on my ls2 engine. but i am a very **** person i like design perfection. For my next engine i will spend a little more money if this part will work. Is it need i dont know but i like to over do every thing in life
that thing looks stout as hell
