how much boost could i go safely with 10.5:1?

right now i am gonna be doing a dp 100shot but i am planning to boost in the near future. i have spoken with others about this i just want to get some other opinions. the main reason i ask is because the pistons arent in yet and if i need to go lower i want to do it before they are in.


10:1 forged je pistons
ib spec h beam rods
darton sleeves
hondata s200
fully worked head milled 20 thou.
etc...

 

no comments? anyone with exp. on higher than normal boost?

 

high compression + boost = detonation

 

im running 10.5:1 on my setup.
It's going to be done next week and in the car in a week and a half.
From what ive heard the most I can boost is from 10-15psi. Thats with the WHOLE ENTIRE block being built and running a AEM EMS TUNED. Like i tell everyone tho. Its mostly a street car thats why i kept it @ 10.5:1 and i dont know 2many 300+ hp Daily Driven street hondas around here. Plus you can always Take it to the Track run some C16 and up the boost to about 25psi and run some HOT numbers.
No im not going to tell you my setup.
You can wait till next week when i have videos and dyno sheets up.

 

If I remember right allen with the blue hatch is running 500 something whp on 10 something compression. CHeck it out at http://www.cheesefrog.com

yes

 

yah i think that guy's CR is @ 10:1. pretty bad *** if you ask me. and it made 372whp@9psi. that's why i was somehwat happen when my end compression ratio with my new head went up to ~9.4-9.5:1

And so does low compression + boost.

anyways, with your set-up you should be good for 500+whp, how much boost that is? depends on the turbo size. It could be 30psi with a t3t4 or it could be 25psi with a sc-61...
With high compression you need more precise tuning to make it work safely.

exactly what I was going to say

 

If you motor is built properly, your fuel is up to par, you have a tuner that's familiar with tuning turbo Honda motors and is familiar with Hondata you should have little to no problems putting down a good amount of power on pump gas. Like Soon_2b_evil said. He should be done within two weeks. His motor is between 10.3:1 - 10.6:1 with a good sized turbocharger.

thanks for all the info guys
thats just what i wanted to hear. my car is mainly gonna be a daily driver too. plus for now i dont want shityy n/a #'s bc im not boosting til later. i gotta a good bulider/tuner, anthony(precisonh23a) is doing it all for me . i trust him.he knows his ****. i just wanted to hear some other opinons bc this setup is not the avg.

 

no problem man. I'll let you and everyone know how things go, when its all done.

 

Id say with that setup up you could make some serious numbers...With higher compression your gona have better streetability because low end power before the turbo spools will be better
