Keep in mind that the 7,000 rpm redline is only a temporary redline, and the static redline is still at 6,250 rpm. I do agree that it would make sense with PMR's and no ability to repair scored cylinder walls to keep the revs down.

oke:there goes my entire week of lunches. thats alot of money, i dont know i can swing putting that aside.
makes sense, let us continue to mod our cars to the extent that you did so we blow our shit in anticipation for a written article from magazines that are basically useless now that the internet has taken full force.
It doesnt really affect me, I dont plan on going hog wild on mods anytime soon anyways. Tune/exhaust should be just fine for me.
Honestly, we know the rods are the waek link. I am sure with a 3.6l KB with a small pulley and race gas would have no problem poppin the motor, epsecially since they are going to be revving the piss out of it. I think if you are going with that set up it would be wise to limit it to 6200 rpm, unless you feel like making a window in a $4500 block.
I just want to see what the car with longtubes and a KB 3.6 does on 93 octane.

Unfortunately on this new 5.8 Trinity a blown motor will typically be more expensive than it was in the past. There are no clean up hones when you score a cylinder with the new PTWA cylinder walls. I still believe that with the right power adder that this motor should be capable of 800 rwhp with a dead on tune, and some degree of mechanical sympathy by the owner. Or you could do like some do, and forge the internals before you add a significant amount of additional power.

We already know the limit of the stock block. It has the same rods as the previous GT500's. 725-750 RWHP @ 6250 rpm and a 'proper safe tune' is about the most you can go and still be safe on 93 pump gas.
There is absolutely no need to try and prove otherwise by upping the power without first changing the internals (rods) before going to the next level if your goal is to all out race the car.
I doubt very much that Evo was looking for the "limit" of the short block they are already very well aware of it.
Spoke with Lund today and 850 wheel is in the safe zone, Evo was pushing it and thats how you go faster than any one else. In order to be the fastest you have to put it on the line. They have in the past and continue to constantly push the element. KUDOS to EVO for laying it down reguardless of the outcome. On to bigger, stronger, faster and more power! L & M/Michael Rauscher racing engine on deck!
I would assume that the new engine is 5.4 Condor based, and not 5.8 Trinity based? Thank you for weighing in with the info, and that estimate is ~ 50 rwhp higher than I thought.
I too am wondering if they were able to get a 2013 block and have it built already. It is in the system already. If not, I am guessing they will ise a sleeved 2011 block a big bore to get back to 5.8.
It's not some absolute number. Way too many variables for that. 750-850 is probably a reasonable range, when you figure in all the outside influences at play.
im sure they will just sleeve a 5.8
and still waiting.
subin........
I remembered a video interview with Jamal Hameedi concerning the 5.8 motor and he stated the reason they went with the plasma sprayed bores rather than steel sleeves.
Go to 2:27 in the linked video for the explanation.

850rwhp safe.... no way is that safe with the rods etc in these motors.(specially at 7k RPMs)
That's about 1000hp flywheel hp plus the HP it takes to turn whatever blower is on the motor which can be 100-200 addition HP.
These rods can NOT handle 1200 crank HP
If someone feels 850 RWHP is safe zone for these motors , I would think that is a pretty good reason why it didn't last.

do you even know who John Lund is? If that is truly what he said, id take his word over yours.
I believe- or atleast read that Mr Lund worked with Ford when they were tuning the engine. If that is true- ill believe if he says 850rwhp is safe, It's safe.

OK
whatever 850 is safe LOL
I am sure TOB would just love to answer you about these Rods in these motors.

Yes I do
Sounds like you think I am a beginer at this ....
Guess again
Sorry but 850 was not safe on the 5.4 and is not with the 5.8
You guys believe 850 is safe go right ahead and try it.
Just make sure you have a spare motor to replace it ...because it will not last for too long
