Ok, I watched the video at my friends house about a year ago. I dont remember most of the tricks he used. But I do remember something about the difference between gsr bearings and ls bearings. I just cant remember what it was. Could you guys inform me on what that was? thanks.

 

The gsr/itr rod bearing is 2mm narrower then ls/b16 and has a trick coating on it that holds more oil. Also the bearing is more durable for high rpm use.

 

The width of the LS/B16 rod bearing is wider than the GSR rod bearing. They do share the same spherical dimentions for oil clearance. The narrower GSR bearing offers 3 main benefits.

1. The GSR bearing has less oil film surface area which reduces friction at all rpms.

2. The GSR bearing has a special coating that helps retain upto 50% more oil than conventional bearings (according to honda).

3. Not as significant as the other 2 reasons but the GSR bearing is lighter by several grams because of its narrower dimentions.

These 3 things add about 2+ hp. at a minimal expense of changing the tang location of the bearing. (moving it inward)

Many newer vehicles use design parameters that reduce engine friction such as offset cranks, smaller and narrower journal and wrist pin diameters. Anytime friction is reduced or weight of reciprocating or rotating parts is reduced there are host of benefits, including power production.

aaaaaaaaah thank you very much.

 

sounds like a plan!

IDK about you but I try to keep the bearing from contacting the crank at all

Yes, that is correct, but what omni was meaning was the oil film is developed by oil following the bearing and crank journal surfaces. Thus the gsr (smaller) bearing will have a lower friction losses compared to a ls/b16a bearing.

 

learned something new today

Hah, yeah. If you guys bought omnimans video you would learn a whole *** load more as well. So many different trick to gain that extra little bit of HP. Of course I forgot all of them lol. But I want to buy it, but 80 bucks is a little steep.

 

thanks for the comments on the video as far as the price, its always been available through me direct to HT members for less. PM me if you are interested.

Thanks!

He just meant to use the term 'surface area'.

 

less bearing surface contact = less friction

 

I ordered the video yesterday, cant wait to start the learning process...

 

there are some interesting articals on google about auto manufacturers off setting cranks to gain a little more power and also using smaller and narrower journal diameters and smaller wrist pin diameters as well. its not for every application but they have found significant improvements from doing so.

The crank offset basically moves the centerline of the crank off to one side slightly so during the power stroke the piston has a more direct path due to a better rod angle. The toyota prius and the insight both use this feature.

 

do they also offset the wrist-pins in the pistons?

 

man i hate to ***** but i found the dvd on HT for like 40 shipped. just search for it in the market-place. i forgot what store had it... thats a steal

Where can I get an offset 92mm B-series crank?

You tell me?

 

can you use gsr rod bearings on ls rods???? and a ls crank???? i will be using a gsr blcok with ls rods and crank

haha maybe i didnt explain that with the utmost clairity.

The offset refers to the main journal bores centerline in relation to the centerline of the cylinder bores. Instead of the crank centerline and the cylinder bore centerline being the same the crank centerline would be offset to one side.

And yes you can use GSR rod bearings on LS rods and crank as well as b16 rods and crank. You simply retang the rods and turn them around. its all explained in the video.

 

would it be better to use the Ls bearings on the rods,and then GSR bearings on the mains? Or switch both to GSR for less friction?

 

omniman, you rockzorz. I love your vid. I need to buy the video. Which im going to do. Im not joking people. If you buy this video, you will be so suprised how many tips you get. Its amazing.

 

steve comes out of the woodwork. awesome.

edit: i ordered this video from iraq. first 100 or so they made. it was the only dvd i had for awhile with my little 6 inch screen dvd player. so i watched it over.... and over and over and over again. add that to the truamatazation going on, and i can recite it.

"they used to call me omni man because i had a dodge omni and used to go to the street races. they would all day, here comes the omni man. the valves in the head were tiny and the only way you coudl make any power was to turbo the thing"

see. its pathetic.

haha, i remember when he shot the pistons. I thought, holy ****! I couldnt believe they held up to that. Man, I needthat video.
