They are a little to short so when everything starts to lift it starts to strip out the block
So let me ask you all, you guys are building blocks with forged parts,but not going to push it, these motors are living at 700. If your turbo isn't making these numbers, why spend the money on forged parts when oem has been proven? I could define to see is you plan on hitting higher numbers, I read a few builds, most go with forged pistons,but make 500 hp. We're is the weak spot on these motors?
My goal is to push the limits, I have the precision 6870 turbo which is rated for 1200 and I'm going to be running a 50shot of nitrous. The goal is to hit triple digits, but the main goal is to get the 1/4 mile record which is going to be very hard to do being in the location I'm at and having to race at the second highest elevation tracks in America.
As far as weak spots there's no real answer, my piston ring let go which is why I started this build where others ran into different issues.
Sorry meant now I see your goals! It's was more of an inquiry but ya, that's a well put list of must haves.
Ya I figured thsts what you where getting at, just sharing my goal and where I want to be as long as everything holds up
Did you mean quadruple digits? I too am striving for the 1000hp mark and have built my motor accordingly. I have the ARP head studs and have never heard any issues about them. Only the modified studs Alex was using on his punisher motors. Which A/R did you decide to go with on your 6870?
Haha ya, I do mean quadruple, had a dumb moment. Crap I can't remember the a/r now, I believe it's a 1.00
No just been posting updates on this thread, once everything is completed I'll most likely make a build thread
I am not using a single turbo. I am going with GC twins. Which means i will have 600 torque on low rpm. That is the reason for my built engine. Weak part is rods with bend. And people have had pistons and ringlands break. So at 132k i planned a rebuild anyways and just want to do it all at once. Also have room in the future.
Keep the power in the 650-700 range and enjoy it. If I ever get bored maybe I'll piece a built shortblock together and do rods/pistons. I'm really not trying to build the motor though.
