621whp and 553Tq STOCK BLOCK by Ostar Motorsports

[rhamlinii]

ARP rod bolts certainly DO alter how much a block can rev to and tolerate. . .

You can say a filled block with methanol for fuel is a stock block too; if we're going to use these: " ". But we don't because we know that pulling shafts and swapping head bolts has nothing to do with how much the stock block hardware can tolerate. Everything else not mentioned about a build that is "stock block" is "keeping secrets". . . Flat out lieing. . . .

Yes no b-shafts could save a block that is being pushed. But we're all out for the same goal. And removing shafts doesn't add to or take away from the limits of the stock hardware supplied. It's only that a spun b-shaft may prevent you from seeing the limits of the stock hardware. Different fasteners, like different rods/pistons, means different limits. For talondrift it would be advisable to upgrade. Because he is on "stock block". But it is possible, as proven here even, not to need to.

There you go. What the hell does a "filled block on methanal" have to do with a "stock block" record? It's always one damn extreme to another, with you. I'd rather not go off topic, but I will reply. The strength of the crank, rods, and pistons ARE STILL USED AND "PUSHED". "Fasteners" are not that same as upgrading rods, pistons, crank and or block. A "stock block" does not include
stock or O.E bearings, oil pump, gaskets, water pump, B. shafts or fasteners.

"ARP rod bolts certainly DO alter how much a block can rev to and tolerate. . .".

, so does B-shaft removal. So get over it. I can use stock rods at 9000 rpm with stock rod bolts. You, however can't do the same with balance shafts in a stock motor for obvious reasons. So it does limit a stock block, because it is the limiting factor. POINT...........Stock block is just that. Block, rods, and pistons. If we need to label ARP hardware? I really don't care, but it's not a secret.

For talondrift it would be advisable to upgrade. Because he is on "stock block".

Well that makes sence. Who would argue with that if he could afford the investment?

Stock block(form a fat guy that assembled it form the factory).

 

[OstarMotorsport]

well just to make it clear, my block is stock untouched from the head gasket to the oil pan drain plug. But im not the only one, so its safe to say that it holds together very well with every stock component in place.

Do you still have the b-shafts? If so what rpm do you shift? I'd really be curious to see if mike and or todd still have there b-shafts aswell? I know Mike has a rev limit set to 10,000 rpm. I'm not sure about to Todd, as I already said.

I did remove the balance shafts but nothing else has been taken off or added to the bottom end. I dont know if you can see it on the graph but i only rev the car to about 8k. Reason being is that the car makes no power after about 7700rpm due to the stock intake manifold.

That's incredible. That not only the rods take the pressure. But aswell, the fasteners holding it all together KEEP it all together. . . That's a HUGE deal to those who actually want to know.

Swapping components that literally hold together the parts in question to other fasteners that are good to over 900whp tends to cause the entire community to say that said shortblock is NOT stock. That is something one can get over too.

You can't comment on rod strength without commenting on the fasteners used; of which, they are such an upgrade as to distort the rod causing a good builder to want to rehone the big end. It is a secret if you don't say what you did to modify the coupling of the stock rod caps to the stock rods. . .

Pulling shafts isn't increasing the stamina of the parts in place. Balance shafts can just take sh!t out prematurely. And it's not like there isn't a stock removal kit already in place. There is at least one Sirius motor without them even from the factory. Pulling them has nothing to do with strength. But I guess those frowning would charge, "It's not stock if Ostar pulled the b-shafts." So would the rest of the world chide, "It's not stock if one pulls b-shafts AND uses upgrade fasteners for the most critical component to block strength". . . Still who has proven the most?







Speaking of 'extremes', 'One extreme or the other'? Give us a break. It is just as extreme to claim arp rod bolt upgrades are only as significant as swapping the bshafts for the 4g61 parts; as it is to say, well lets jsut fill it and run methanol. I was giving you an example of the same extemity for YOUR sake to understand a bit of why the rest of the world already has made a decision on what stock is. You can certainly come on here and bellyache that it doesn't follow personal chosen requisites, but the rest of the world knows what a stock block is. Why is this so irritating to you?

I am now even more carious to see what is all in "the stock" block now. "stock" is not what it sound like to be after all.

OstarMotorsport, dude, its amazing what you can do with your car. congratulations to you brotha once again.

For those of us who has little to work with on our motor, i would like to see an honest answers to hope for.

Not intended to flame anyone, just looking for detail/honest list down to a single bolts. thank you.

 

[dsm-onster]

He just said. . . Only removed b-shafts; nothing else done. That is stock. Disregard some folks personal issues with the matter and listen to what the actual record holder has said.

 

[toddmeunier]

I removed my balance shafts.

Removed balance shafts out of my motor...Everything else was the exact same in my shortblock from the day it left the factory. Had 112k miles on my shortblock. I had ARP headstuds in mine with a non oem gasket(NOT oring'd)I think it could have taken more than what I made too. I dont see 700whp being a problem on the stock shortblock. Had I not already torn mine down for a new build, Id try for 700whp.

These motors are only as good as the user though. I thought out my build and made sure all the time that my tune was dead on. Usually logged a pull every new tank of gas. At the point that I was though, I didnt care wether the motor held together or not, so it was not a conservative tune by any means.

E85 works wonders!!!

Though I listen to pretty much all this guy says . . . In specific, the above are great words of wisdom!!!!

 

[talondrift]

how dangerous it is to keep the stock balancer shaft and rev 8000 rpm and making between 550-600awhp .

can i run it safely or you recommand to change it before i go to the dyno making some good numbers.
thanks for your answer!

I cant tell you if it is safe or not as i havent tried to make big power with the balance shafts in....Though, as simple as removing the balance shafts is and as inexpensive as it is, its one less thing to worry about.

No reason to put a motor at risk cause you didnt want to spend a couple hours removing them.

Yes, that is sentiment, too. They spin at twice the rpms as the crank. They have bearings. Something COULD happen. Not worth keeping them in just to have a little smoother ride.

Yes, they spin at twice the crankshaft rpms. Nuff said

 

[talondrift]

ok i know what to do now thanks guys !

 

[rr06rs]

Are the tracks around you guys still closed? I want to see this thing pull 143+ like it should!

 

[OstarMotorsport]

we should be at the track in the next few weeks !!!! We will be at NSCRA

 

[talondrift]

with some video please !!

 

[OstarMotorsport]

If all goes well i will have a vid up as soon as the event is over.

 

[fantompr]

Congrats 139mph close to 9sec

 

[rdgsdsm]

congrats hope you get out of it what your looking for

 

[OstarMotorsport]

Well guys i finally was able to hit the track after a long winter break .... Here is the vid

YouTube - MVI 6480

 

[coppersmith]

good damn run! street tires?

 

[Armandotech]

No, the car is on m/t slicks
