My set up is
lq4 short block
texas speed 2.5 317 heads
224/228 114lsa camshaft
fast lsxrt intake
kb front mount kit
76mm ebay turbo
3.5 down pipe
fmic
stock tb
60lb injectors
walbro 255 intank
the plan is to tune it on the 10lbs
She is at the tuner right now i should know the numbers later today or tomorrow. The person who guesses the closest gets a cookie



Well flaco did his magic and we were having some waste gate issues couldn't get it to hold 10psi. it would peak and then fall off to 6.5lbs so at 4500rps it made 547/549 it would lose power from there.

I will be changing the spring tomorrow and crank it to 12lbs and she should be 630ish

 

625rwhp 690rwtq

 

My 6.0 put down 625/660 on 10psi. I'm sure you'll be right in that range.

 

I would be happy With 600.
looks like im going to need a 80E faster than i thought..

 

Ill say 675/625. With those heads, cam, and LSXRT it should be a screamer up top!

Good luck!

 

I hope your right!!

how much can the stock bottom end take?

 

Depends of who you ask! I feel like Ive seen anywhere from 800-1000 max.

 

Anyone else have an guess?

 

There is one that we know of thats putting down about 1100-1150 to the wheels, but on a stock intake, stock heads and a baby cam

 

holy **** batman!
