took the words right out of my keyboard!!
but as everyone else said... bigger = more flow

I can tell you that the 40mm HP can handle 30+psi and over 600hp.
FYI however, the 35mm and 40mm are discontinued. They are being replaced with a 38mm, and 44mm.
The 38mm HP will be be able to handle pretty much everyones goals, unless your shooting for the moon in hp #'s.

So is the 35mm able to handle up to about 20psi? I would imagine it could do that. If not, let me know.

Does the 38 have the same flange as the 35?

Re: whats the difference between tial 35 mm wastegate and a 40 mm (hpfsi)
for high power (it even says this on the tial site) , you would want a 35mm, cause you wanna use more xhaust to make more boost, i agree, it doesnt make sense to me to put a 40 on a fast car, you would actually want a smaller one so , just myopinion, actually best thing is the hybrid, thats what i use

What?
That is true to some extent, but why do you see 46mm+ Wg's on 800hp+ cars then? Those cars generate so much exhaust flow that it REQUIRES a larger valve to makes sure it doesn't KEEP producing boost.
Also, larger valves are great for those who want to run 30psi at the track and only 6psi on the street with a very large turbo.

that might be a good idea if your a big fan of boost creep

The way i understand it is that with higher boost you are letting more exhuast gasses go past the wastegate, so intern you would only need a smaller wastegate since you are using less of it. With lower boost you want to be more consistant and you would get that by using the bigger wastegate. If none of this makes sence dont worry i just got off of work, and cant think right.

That is a wives tale...
while it is true that more of the exhaust gases must go past the WG to create higher boost, you are also inturn creating more exhaust gases at those boost pressures thus needing the larger valve to PREVENT any further boost production.
It totally depends on the turbo. If you have a T-25 and boost 30psi (not that you would) the 35mm HP will do fine, because it has to flow a lot less gases to produce the 30psi than say a straight T4 would.
The main basis behind choosing a WG is if it can flow enough gases to prevent boost creep at your desired power output, NOT by the boost pressure it can handle.

The difference between the 35mm and 40mm is the 5mm larger valve to vent more exhaust pressure/gas. The housing and diaphram are larger accordingly to compensate for the larger valve size.

OK, i kinda understand now, i hear what youre trying to say, my theory (also teh tial one) i guess does make sense ,but i never thought of it like that, but i mean for all the daily's around here, 35mm will do, im sure plenty of people pay teh extra $$ for the 40mm for no reason, but the comparison of a 6 psi daily car that would run 30 at the track is also a good true idea,
anyways, i went 35/40 hybrid, in between,

Definetly.
The 35mm can handle a lot!
I choose to go with the 40mm for my setup which was most likely over kill, but I am going to be one of those 9psi on the street/25psi at the track people using a quite large turbo. I wanted to make sure I had enough valve to prevent any possible boost creep.

Re: whats the difference between tial 35 mm wastegate and a 40 mm (Bryson)
after reading all this i still can;t figure it out...
Can the new 38mm bolt onto the existing 35mm flange on the manifold?
