FishWick 21 Posted March 16, 2009 Report Share Posted March 16, 2009 Depends on the turbo size and target boost pressure. A GT35R sized, I'd use the Tial 44mm. GT30s are OK with the 38mm, but bigger is better with low boost (up to 15psi). Link to post Share on other sites
Bobtrude 0 Posted March 16, 2009 Author Report Share Posted March 16, 2009 Why is it better with bigger ? Link to post Share on other sites
FishWick 21 Posted March 17, 2009 Report Share Posted March 17, 2009 Because if the wastegate and wastegate dump route are restrictive, the unwanted gases will back up into the cylinders, robbing power and increasing EGTs.It's not essential to use a big wastegate in low boost applications, because it's mainly at high revs it becomes a problem, but if your project can afford the space and outlay, then I'd recommend it.You'll hold a better power and torque curve to 7000rpm with a big wastegate than you would with a small restrictive one.
