you prob won't make it past about 12 psi before you start floating the valves. In my experience anyway that's about the spot, different engines and turbos will act different. Best to throw some pacs in and be set imo. They're cheap enough.

EDIT, especially if you're gonna pull it all apart and gap the rings.

I -think- I will gap them 0.028 and 0.030" so that as I turn the wick up, I am less likely to break it.

But part of me thinks I will be perfectly fine sticking to 15psi, in which case I would run .022" and 0.024" or maybe .024" and 0.026".

I haven't decided. It's just going to be my daily; never taken to the track.

from what ive read you need to gap rings if above 14 lbs of boost .thats why im doing ring gap . i dont wanna open the block right now . i may just settle for 13=-14 lbs for awhile an when i put cam in pull the block then . i jus wanna get it running right now

freeky

thanks for the link heres my build page . its gonna be a slow build hopin to get engine in an running by halloween .https://ls1tech.com/forums/chevrolet...3M_ryyspuh0ffA

ugh kinda didnt wanna open up the block. then it would be new hg, bolts ect. FML.

or i can just keep it under 14psi.

freeky

from what i been told an read 10-12 should be in the 500s whp range . im doing that until i get cam . ill prolly add springs tho

panda240ss

10-12 psi on pump or e85? i have a sloppy stage 2 cam and might not make a difference but 102 tb with aluminum intake? already have pac1218s.

my friend made 500 on 9psi on e85 with a 4.8

freeky

should be in the 500s with 93 pump . im really thinking about e85 lately. i know a guy that made 780 on pump with a custom grind cam an a gt45 on 12.8 lbs of boost in a 6.0

panda240ss

I Think i can do 600s with e85 and 12 or 15 psi easy. everyone has been saying so that it shouldnt be a problem.


im switching because i live down the street from a e85 station. so i shouldnt have a problem fueling and its so much better for the car since im going F.I

freeky

they jus starting selling e85 at the sheetz by me . so yeah im considering it .600 sound good.

panda240ss

i would to be honest. theres alot more benefits for it. unless u do long drive and ect then ill say do flex fuel. since its my "racecar" ill just run e85 only.
