im embaroused to have to ask this, but its been a year since i put a rod through the block of my 9.

i have a new evo 8 and i want to build it right from the get go.

i know engine knock and pre-ignition are inherent with our vehicles. this was obviously the curse that killed my old evo (which i had to sell as a rolling chassis)

anyways. i am looking for preventative measures that i can take to prevent knock and fortify my new evo.

I WILL NOT USE METH OR NITROUS ive seen too many people spend rediculous amounts of money on these systems and even more money on failsafes! these are not viable systems, i dont care how long youve been using yours, your taking that risk.

so that being said. i know there are various coatings out there that draw heat from specific intake parts. so will reducing the intake air charge lower knock?

i know higher octane fuel is an option (we have 92 here in washington)

will a larger radiator help with this?

will a larger intercooler help this?

will a higher efficiencey oil cooler help this?

will larger injectors help this?

anything else im missing?




i know from a tuning standpoint reduction of knock is achieved by enriching the air/fuel mixture.


im looking to make 450-500 horses on a stock bottom end.

 

Any e85 around?

 

no there are no e85 stations here.

 

bigger injectors just reduces the chance of running lean depending on the mods, and a bigger radiator is just for a better flow might keep the car temp a little lower, but as far as reducing your knock count, run 92 all the time, try a better quality 92 nothing from wall mart, and get a good tune on it and keep an eye on the knock you should be good.

 

agreed

I never thought I would say this, but meth cant be that bad

 

Its spelled embarrassing, I would suggest a full tune up and a ECU tune. Maybe something with a extra knock sensor like the Dtec or something.

 

come on, don't be rood...

 

meth! suck it up
