Hi

my engine comp.ratio is 9.5 and i will use 20 psi do can I do that with 98 octane fuel

thanks

 

How built are your internals? I dont think that the information you gave us is enought to answer your question

 

Yes. With the proper tune.

 

are you sure

 

the internals can handle more than that no worries about them
my question is can I do that with 98 octane fuel (use 20 psi with 9.5 comp.ratio )

 

Intercooled?

 

meth...

 

Where are you from? (Is that octane rating R+M/2?) Also, 20psi doesnt exactly mean much. How much HORSEPOWER do you plan on making at said boost? What ci? list as much about your setup as possible please if you want accurate answers.

 

Yes it is 98 octane fuel and with that boost I plan making 700+RWHP and I said dont worry about the internals and ci or the tranny I am only asking can I the 98 octane fuel handle it with 9.5 comp ratio

 

yes it is

 

are you going to spray or go turbo or both lol? Why do you keep starting all of these vague threads in different sections with no details on your setup? If you want help give more details on your setup. Out of all the threads you have started, I don't think anybody knows your setup, so how can you expect to get accurate answers. Fwiw at 9.5 compression 98 octane most likely won't be enough for 20psi, but again more details are needed to give an accurate answer.

 

No. Running twin 91mm turbos at 20 psi will make way more power than your desired goal, and i beam rods, and off the shelf diamond street pistons can handle. It will likely create too much cyliner pressure for 98 octane.


Like everyone said. Give a DETAILED description of your build if you want accurate answers otherwise our "advice" will be useless.

 

Since the thread is pretty much generic. You can make 700rwhp on 93 octain and 12-14lbs of boost.

 

thanks guys

 

Hey guys, I have an ls1 and want to make 700hp. What can I do??? lol

 

^^^Slap on a Street Warrior intake, twin turbonators, and whistle tips... Should definately exceed your goals... lol

 

I am boosting 19.5# on a 427ci running 93 octane / meth.

 

He hit right on the head? Boost is a measure of restriction, an example is you can run 100lbs if you put a tennis ball in the intercooler piping. So cam, heads, intake will make more power with the same boost since your moving more are at the same restriction measurement.

Your real measurement should be horsepower and torque.

 

I put down 650 RWHP threw my 4L60 which is close to 800hp est engine on only 9 psi on my 364 (9.5 to1) CR on 98 octane with no problems at all .So 20 PSI might be over kill to reach your HP needs? The less boost you run to reach your HP goals the better you are and is way easyer on your engine IMO and wallet in the long run LOL
