Just wondering. Why don't I ever hear of guys on here running like even a small 25 shot ? Wouldn't that help with spool and cool intake temps a lot ?

 

Well right now. I'm huge on turbo compared to fuel.

I'm on stOck headbolts. Ferrea valve train. AFI kit. And a borg s300sx fmw turbo. I have a Walbro 400.

So I will probably run out of pump on e85 by 540wheel.

I was looking into running less boost and a 25 shot for when I race. I figured it will help with spool and make about 570. If that's even safe on stock headbolts?

Looking for some guidance on what to do I guess.

I figure 2 less pounds of boost and a 25 shot will help with intake temps and shit.

But I have worries about water meth being unreliable is all. And I figured to help spool.

Not sure on where to turn

 

Get head studs before you consider anything else seriously arps are like 150 bucks and will save you a lot of money. Personally I don't think you need it my buddy has a 91mm turbo c6 vette and he going to be doing this. Unless your into very competitive drag racing I don't see it worth it

 

I dont think the turbo you run is all that big. Its a mid frame, and it works well on the street. Nitrous adds a fair amount of complexity to the system, and unless you drag the car is not really worth it.

Some meth systems do fail, but getting a system with dual nozzles will help reduce the risk. However, running E85 makes the need for water/meth injection go out the window. You could safely get a smaller turbo and run more boost, decreasing spool time and maintaining power.

One thing to note: if you run out of fuel at 540whp, adding nitrous will not increase the amount of power. Nitrous molecules break down under heat and effectively increases oxygen in the cylinder, which increases the amount of fuel you need.

 

Yes but I figure, instead of 20lbs. Run 18, add fuel and nitrous. I figure the cooler air and spray will make
More then the 2lbs of boost and be safer and help with spool.

 

If the air temperature drops, so will the boost pressure. Not to say horsepower will drop, because pressure and mass flow are different. If you are running E85 the lower temps arent necessary. Ive seen guys run 40+psi on straight E85 with no problems, and thats whats great about it. It has a very high resistance to knock/pre-detonation so you dont need to worry about the safety margin.

 

So. As for studs. Do I need to have the head leveled ? Or can I just gets new gasket ?

 

Like. Technically. Couldn't I pull a headbolts, and put a stud in, then pull another head bolt, and put in the next stud and so on and so forth. My gasket isn't blown, nothing is wrong as of right now.

 

Just check the head with a straight edge and a feeler gauge. Even if it's off a few thousands off it's worth it just to have it machined. The worst feeling is to have everything together and you turn the car over and oil starts dribbling out just cause you were to cheap to to pay 80 bucks to have it machined.

 

My car has 25k on it. I know people who do studs with that method and work fine. But I wouldn't be asking you if it didn't make me nervous on my own car haha
