I'm setting up everything for my turbo project. All parts get here in a week, so I just want to sort out everything right now. I have a turbosmart manual boost controller, but I would rather not use it. I have a Tial 40mm wastegate on the way, but I dont know what bar spring comes with those. I was just thinking of buying a 1.2 or 1.3 bar spring which is approx. 17.40 psi and 18.85 psi. And for the base tune, just use the spring that comes with the wastegate which is probably around .5 bar. I really wouldnt need to change it, cuz im sure 18 psi will be enough for a while. What do you think?

 

What motor? Ur gonna be running 17psi on a newly boosted car?! Are u crazy?

What's wrong with that?

My bad, i thought he was trying to jump the gun and start off at 18PSI

 

Sry for the little amount of info. It is a volkswagen, but i'm on the honda-tech forums quit a bit. The motor is a VR6 with JE 83mm 9:1 compression pistons, and steel headgasket lowered to 8.5:1 compression. Motor bored from a 2.8L to a 3.0L. P&P head with heavy duty valve springs. DTA P8Pro standalone engine mang. Motor already has about 2500 miles, so its nicely broken in.

 

anyone?

 

sorry we do not help volkswagen owners...

jk ...well if you have the boost controller why not use it?

 

yea i would put a boost controller on it.. but thats just my 2 cents

 

At that level of boost, you'll want to use the boost controller.
