or you can be a retard like me and got with 7.5-8:1 and have 650hp on pump gas

but yeah... what he said

Let's see it?

Tony1 and Jdogg as usual are on target. Chosing your compression ratio is a very simple process. You first need to chose what power you want to make. Then you need to chose what gas you plan on running. From there chose the highest compression possible to run the car safely and efficently. So if your goal is 300whp on 93 octane, you can run mid 10s compression and still find the holy grail of tunering, MBTT....Efficency is the most important thing in cars.

 

so what if ur power goals are 550whp to 650whp on 91 octane?

 

you arent gonna make that much on 91, never ever.

more like 400-450 on 91

 

then what will it take?

 

what compression ratio?

 

9:1

 

or whatever is best, cause i havent started my build yet. I start next month, right now i am just planning cause i like to go into it with knowledge and a plan of what i wanna do. so i aint lost

 

on 93.. with a very efficient turbo, ported plished head and an overall efficient motor, 400-450 is reasonable

 

i want 500whp plus though i am asking what will it take to achieve that.

 

oh and what inline fuel pump setup are u running

 

should i lower CR? or what

 

ok... you guys got me... we dont have a dyno sheet, but we did have 900cc injectors maxed out at 28psi on a 2liter b16 at 9300 rpms... 55psi base pressure.. (smashed oil pans are NOT good for rod berings)

gota be somewhere close to 650hp. my h22 will be done in the next few months.. we'll see.

not 650hp... but i do have several customers with mid 8:1 compression with ~475 on pump daily boosted with around 15k miles on the motor... couple stock sleeves even.

but yeah.. pump gas.. the lower the better, pump gas sucks

 

so if my goals even reasonable? cause i have a b18c1 motor i am goin to start building in about a month. and i have researched, asked questions, and everything. now that i have what i think is all i need i get this it cant be done ever on pump gas. soo can someone help me?

racegas

here is my fuel setup

aeromotive a1000 fuel pump
aeromotive regulator
10-an feed lines
6-an return
earls fuel filter
erl performance fuel rail
precision 1000cc injectors

 

can i achieve 475whp on pump gas? and then with racegas get well over 500whp? cause i am wanting a pretty raw car. i just need help on if its possible, cause i am goin to go with the best parts out there and build the motor top to bottom. nothing is going to be half assed.

 

you cant do it on 91 IMO safely

 

so how do u plan to reach 500whp?

 

i have a very efficient motor with very extensive port work/ custom parts/ custom turbo, etc. plus i have some very hard to get parts through sponsors

 

hard to get parts? So your saying its possible for you but not me , cause u have hard to get parts that Icant get my hands on? and how about did you receive these sponsors?

 

the easiest way would be to use some wiseco shelf -18cc pistons, get a GOOD head (rlz of course ) a nice tubular manifold, big turbo, good intake manifold and you shouldnt have too much trouble with 400-450hp.

i have never tuned anything with 91 octane... we dont get pisswater on the east coast, but it should be doable

 

pisswater? I am on the east myself.
