it is an h22 pushin 25+psi, 500+ whp, at the track. less on the street of course, but it needs to handle the duties of the weekend. both are 40 mm. the price is about the same, from what i have found. also how hard is it to chang the springs?

 

I don't think you can go wrong with either wastegate! The HKS unit doesn't look as nice as teh Tial , but it works just as well.

 

This is a win-win situation, you can't lose with either one.

 

The new HKS Gen 2, or what ever they are called, are dope.

 

Damn, they are hot!!! Do they fit in the same flange as the previous HKS???

 

Well yes and no. They use a V-band.

 

id say Tial, ive had both, and i think the quality of Tial products is second to none, and there are my 2 pennys...

 

thanks guys, went w/tial. .45 bar spring, low boost in first, ~2 bar in 4th via an avc-r(maybe)

 

I dont think the 35mm Tial will hold 2 bar. This is what my problem is...think im going with the 40mm gate.

 

yep, thats why i went 40 mm, starting to wonder if i should have went 46 mm

 

hks

 

if you have a crazy built 6 cyl get a HKS racegate. Anything under 600whp the tial 40 is the best wastegate made.

 

with the tail you can only double your boost. so if you have a .45 bar spring, the highest you could run is .9 bar or around 13.9 psi

 

is that true?
seems weird... i thought when you installed a boost controller the spring was bypassed... ??

 

Tial is coming out with a v band wastegate in January. In 44mm and 60mm.

Tial gets my vote!!!

 

well im only going by what b18bturbo aka viren said. he said i could go over 2 bar w/this spring, with the aid of a bc.

 

with a boost controller on any tial you can go way past double as long as your turbo can produce the boost it needs to suffice the air flow.

The tial 35mm are good in the range of 350-400hp anything above that use the 40mm or 46mm the hks wg is also good choice but the flanges are way different that most of the std wg you see .

 

I have a 46mm and it works fine..for low boost and when u need to turn it up at the track..If u have the $$ go for a 40mm/46mm especially if u plan on turning up the boost at the track.
