like the topic says. is it hp related? amount of psi? cylinder pressure? i want to know because i would like to see how much power i can get out of my setup on 91 octane without blowing it up .

 

On a 9:1 motor, 400 WHP is very attainable on 91 octane. You can't even hook up that much on the street, so why try for more.

 

ran 20 psi at an estimated 425-450whp on 93 pump.

motor is sleeved, 9:1 b16

EDIT: this was on a street tune

 

i made 519 on pump 91 octane
street tune on 13psi

 

what turbo, displacement?

 

here is the linkl for ya

ur motor blowing up?

 

id also like to know, gonna be running a B18B1 94 octane with forged rods, pistons and the RM cam package eventually.

 

I made 358whp on a mustang dyno @14 psi w/gt35 turbo on a sleeved 9.5:1 gsr. I felt comfortable with that on 93 octane.

 

what A/F ratio and timing you guys are running on 91 pump gas?

 

what does it matter? if you use alcohol injection you can make 600hp+ on pump gas, and alcohol is $0.77 a bottle at walmart

rubbing
denatured
methanol

etc...

they all work

 

would you inject just the alcohol or mix it with water?

IPA that you get from the drug store is already 30% water.

 

so you'd just buy some bottles of whatever alcohol and use them in your alcohol injection system? i kind of thought itd be more expensive...

 

I'm not sure if IPA is good with its 30% water content. You also are unable to distill the alcohol out of the water when they are combined in this ratio. It's not as simple as dumping alcohol into your motor...you'll need a way to control the amount of alcohol going in, and then tune for it.

I think hybrid901 did it on pump 93 with 10:1 C/R.

Whaaa?
13psi?

 

IPA is good if you're in a fix and need something to dump in quick. I got a sleeved motor for a great price, but unfortunately it was already 10:1 compression, so I run an alkycontrol meth injection kit. I buy Sunoco methanol in drums, it's about 2 dollars a gallon and I usually run it straight.

And a gigantic GT4067 + 4" downpipe doesn't hurt either
