what is the highest boost people are running on stock head studs ? i just got my car dynoflashed and dynoed by al on friday and i know he was running 1.5 bar like it was nothing so is anyone here running anything higher on 93 octane? i have a fuel pump , turboback, intake and other supporting mods i just want to know how safe i am. should i be worrying about blowing a head gasket? please let me know asap

 

Boost really isn't the issue......knock is the issue. I know people that are running 26PSI on the stock bolts but they are using alchohol injection to keep the knock down. If for some reason they got ahold of some bad gas or their alchy system died bad things would happen.

 

safc2 measures/detects knock. you can also slap on some cam gears and retard timing. Then boost away...

 

stock dont go past 21psi, after u stud....i`m at 35 psi thats enough.

 

wait, what? you're running 35psi with head studs and nothing else on pump gas (93) AZ?

 

I was under the impression that boost alone, without detonation, would stretch your head studs and gaskets, etc. So let's change the question around... At what boost level will harmful detonation occur whithout running race gas or alky, etc?

 

hehe he said : 2003 Evo 8-2.3 stroker-race ported head-1mm over valves-cams-gears-springs-equal length header-T67-all heat treated-NOS-MAGNUS intake-4" custom exaust-CENTERFORCE clutch(single disk) and custom flywheel-cut gears-AEM controls all...2 much 2 list..2SLWLOL

 

YOu can run 22psi with 93 pump gas, stock internals, etc. utilizing a WALBRO Fuel Pump for delivery insurance... Stock turbo will flow 24psi (not for long though).

 

sorry dudes its on c16 n shes fully built...totally dude.look at my sig.

 

we only have 91 octane pump gas in AZ. Then I`m at 20psi only 459whp,low boost.Sounds like u need any boost living in WA. Hows the weather,dude?

 

you have to worry about running lean

 

21 is what alot of people run on stock head bolts. To get higher than 23 you'll have to run 100+ octane gas, and by that time people will have aftermarket head studs for insurance.

 

sorry to hear ....

 

with a fuel pump and reflash you can run 28.2 psi on the stock turbo and internals with 93 octane. Please have in mind when doing a reflash that mail in crap yes it will lean out your car im not saying nothing about that. you must datalog your car (scan your car while u drive hard and easy to view every aspect of your car) then you get a reflash to suit the parts u are running.

This is not just me saying that its the V.P. of ECUTECK with is the same software that al at dynoflash uses and many of tuners.

 

I have not heard of a single instance of someong having problems with the stock head studs. Its all hearsay.
