Lower compression offers a larger window for tuning, thats a fact...the higher the comp goes, the smaller the room for error is.

Keep that in mind.

 

wut kind of "octane booster" are you using? take your car to TonyT1 i think hes in texas. he will tune a stock motor to 400+ whp at stock cr. hes the only person id go to in texas. did alamo ever tune a S?

 

i would like to know as well, in all cases that i have been involved in or researched, the bottle says it will raise the octane 7 points or what not, it actually turns out being .7 points, most wont even raise it 1 point, please someone correct me if i am wrong.

 

I am running my stock JDM AP1 motor with 11.7cr and 13.5psi supercharged with no knocking or detonation. I am also running 50/50 water/meth.

 

Hey, LOOKINCO

What kind of WHP are you putting out??

 

So running a stock Ap1 engine with 11psi pulley on a comptech SC is very dangerous? I am not abusing the engine or track racing but is it really dangerous? Is the limit for stock AP1 compression 10psi pulley?

 

The universal psi for stock ap1 is no more then 9psi

Where did this # come from? not sure...

But if you're having 0 detonation at all RPM and can run 91 octance through any type of weather be it 100+ degree's F and your A/F ratios look good then 11 might be fine.

 

From what I have been reading, +104 Super Octane booster adds another 4-6 octane so, I am running 93 octane it bumps it up between 97-99 Octane, Correct me if I am wrong, but that's what i gathered from a few articles

 

That would be cool, anyone else have info in this?

 

Not even close.



Octane points are one TENTH (0.1) of an octane number ie. 93


Most octane boosters raise you 5-10 points, however there are some that you may find in the local parts stores that will genuinely give you 30-40 points.


Klotz is said to give like 10 octane numbers, but Ive never seen it here locally.
