Hey guys

i am currently tuned at about 25-26 psi on a built 2.0 evo 8 with a 35r kit. the car made 506 whp @ 25psi.

my question is if i were to put straight 110 octane in my car without touching the timing or anything, could i raise the boost up lets say from the 25-26 to 28-30, without having to touch my map at all? or would i need to adjust everything and set it up for race gas.

This would be done on straight 110 no mixture.

im just wondering to see when it comes to track time , if i can do it or if it would be unsafe. plus would doing straight 110 get rid of any knock that i have?

thanks

 

What octane was your current results?

You would see gains immediately with 110. A tune on top of that would be advisable to really make the most of it. But even untuned you'd be ok.

 

my power was made on 93 . im just scraed to see if i made 506 on 93 at 25-26 would it be safe wen i run straight 110 to raise boost to maybe 28-30 psi

 

also will the stock ecu adapt to the 110 and compensate for the a/f since i dont want to adjust things on the tune already. nor do i have money or time to go back for re tune for race gas.

 

A higher octane will give you immediate results. But if you plan on keeping that octane as your regular setup (+ those results) you need a re-tune.

The stock ECU won't adapt but any potential knock at 93 won't be present using 110so your numbers will be WAY higher on 110.

I'm stuck with 91 which is ridiculous...

 

^ nice thats my main concern since i am seeing a small amount of knock but it's enough to pull timing so if i use that 110 then ill gain timing back. and that sucks for 91 man lol

 

I don't think this is true. Your talking of taking a car tuned specifically for 93 octane and filling her up with 110 and it'll be ok? NO that's a 17 Octane difference that's a big difference! I have never heard of anyone doing this actually. Everyone I know that runs race gas is tuned for it.

Of course you'll see gains, lol But you may blow something up, What you'll have to worry about is your timing, and fuel delivery, there is alot more to it than just turning up the boost.

Hey man I could be talking out of my ***, but I don't think it's a good idea.

 

^ true also lol i maybe if i do a 93/110 mix try to get liek 103 out of it or something might be safer

 

do it let me know how it goes man i was tuned on 91 now im on 93 need a retune

 

man that's your risk it's not a good idea. Adding race gas will reduce knock but only if your tuned for it. what your talking about is risky. If you do do it, and turn up the boost, post the results.

Your going to destroy something, tunes are vey specific they push your car to the limit's. They are meant to optimize the car and when you deviate the input it's going to change the output, and in most cases that's bad.

If you want to run 93, and 110 mix then go and get tuned for that mixture. The easiest way is to get tuned for 93, and get tuned for 110 save the map files, and reflash depending on what fuel your running, you'll just need a laptop to handle the flash.

 

^Agreed^ you have to run the gas your tuned for


No don't do it..................... your going to destroy something, LOL

 

lol i was just saying lol hahahahh

 

^ lol ^

 

did he do it yet lol

 

I'm pretty sure we'll know when he does.
