Mods are in the sig. I want to tune for a race gas map but I am running 24psi now! I will be running c16 and I want to know since it's just on occasion can I run 28-29 psi with my stock head studs! I have 405whp and 407 torque on 91oct btw...

 

The amount of boost you can run will depend on too many variables to give a full answer. i.e. how the car is tuned, what the weather is like etc...

 

You should be able to easily do 28 - 30 psi peak (with a green on race gas)....You'll likely taper to ~24psi at redline...But, you'll need to tune accordingly and yes your stock headstuds are fine...

 

Thanks all I needed to know!!!!

 

there is no point to run c16 on stock head studs your car wont support 33-35lbs of boost. You can do 110 octane and do about 28-30lbs if the tune is safe, I would recommend getting headstuds before even running that boost level to not risk damage

 

So you are saying to do headstuds... It will only be for 4 times a year...

 

I'd do the headstuds. It's added insurance!

 

better safe than sorry

 

if your going to run c16 or q16 yes do headstuds cause the point of running that type of fuel is to run more timing and more boost and stock headstuds wont handle 33-35lbs which is wat your going to want to run on a fp green on c16 or q16

 

headstuds wont be needed... i ran 30 psi on the green on stock healdbolts on e85

 

C16 is horrible in my opinion for the stock turbo , I made more power off of unleaded vp-109 than the leaded c16. That and the fact that leaded gas with speed up the deterioration of your 02 sensors.

 

On a green not Stock turbo...

 

stock turbo 9, 30psi tappers to 25, on 110 sunnoco

there has been evo8 turbos as well

key key key, well tunned car

 

Thanks...
I'm pretty Excited to up the boost and tune it!!!

 

Hey Reno hows the car treating you since you swapped out to the green. Was it a ginormous upgrade? I will be installing it(WR) this weekend along with some Studs.
