Boosted ERL 434 Has any one booster a 434 super deck? I would like to run 15-20#. I know it would not be as strong as if it was a 427 because of the over bore. Just looking for precedent and how much boost they have run
Lot of variables , I have boosted a couple , what crank do you have dragon slayer , ultra Billit , is a turbo extrem ERL 434 super deck , 1/2 head studs?
Or is a regular Callie's forged crank do u have six bolt heads ?

with so many issues on ERL blocks to begin with I'm not really sure why you would want to stuff so much high dollar expensive stuff into a block with thinner sleeves and possibility of issues with no support when an LSX block is pretty cheap.
looking forward to seeing the f1a94 results though. not sure why we don't see more builds with that blower. looks like a monster on the numbers i've seen on other platforms

LSX blocks have their problems (early versions) and they're boat anchors.
The only issues I've heard about with the ERL stuff was the dry sleeves would possibly drop a sleeve. The wet sleeve stuff is pretty much indestructible.
We spin a super-deck north of 8500 all the time with the baby 88mm on it. Go through the 1/8th around 7500-8200 depending on what turbo is on it.

Okay, i had not heard of any superdeck issues and after that post i looked around and still couldnt find any issues so i was just curious. Back to the boosted 434? Outside of needed custom pistons any issues?

I have all the right parts in there minus pistons. Cr is 11.8:1 at the moment. Dragon slayer crank, callies ultra I-beams, johnson lifters. Will run flex fuel. Its really just me swapping the pistons and im going to get the block machined for piston squirters. My concern is more the bore being 4.155 vs 4.125 and it being 4-bolt vs 6-bolt. Thats why im wondering what people have done with this in the past. Ive seen a c6 with this block run 8lbs but im not sure if he was high compression

I'd leave the compression in it. It'll make more power and not have to work the compressor as hard.
Can make a decent amount of power and RPM with hydraulic stuff, but I'd be watching radiator/cooling system pressure for sure with a 4 bolt and that big of a bore.

I watched a local guy fight a 427 ERL superdeck 6bolt deal for 3 years with headgaskets. Couldn't keep them in the block anything over 20lbs of boost.
They swapped to a LSX block and haven't had an issue since.

Probably 17-18lbs would be the max on this combo. The pistons i have are not really made for boost, they are k463x155 wiseco. I was going to get the block machined for piston squirters anyway so i figured some custom je pistons for a compression of about 10.0:1 would be better

We change the head gaskets when they start to leak.. usually in the 40-50 pass range.
We shoved 33psi into Ray's 2 weeks ago, went 4.37, .44, .45, .53 (not in that order)on a fresh set.
I think the question you should be asking, is how much power do you want to make, and then realize that you could easily make that power out of a 370ci. Probably even make money off of selling your 434 used, and then building a 370. Just my opinion.

1000whp should do it. Yes just chasing numbers at this point or i would be happy with my 600+. I like to tinker and do new things and was going to make this my project. Would probably be more simple for me to pick up a used 4.125 bore 6-bolt then starting over since my car is set up to run a 4th gen ls7 headed motor
I'd sell it to someone that want a n/a build.
That blower is badass and would make some great power on different block. I have some custom diamond pistons for boost that are 4.125 that I'm selling since I'm going with a different setup.
Don't neee crazy cubes to make power out of these setups.

The car was street raced and tracked raced at the time, I dk if that makes a difference.
