My new Tial 38mm external wastegate just arrived today and I noticed that right on the box it says

**ATTENTION**: Regarding standard WG38mm valves. These valves are not intended for leaded fuel use. You may request a racing valve that is intended for leaded fuel use. There is an additional charge for this racing valve. Extended use of leaded fuel will cause performance problems.

I was going to just run 93 oct through it for the street but also tune it to higher PSI for track use with leaded 110 oct race gas for the added power from boost and timing. Do you guy's still run leaded race through your's or do you heed the warning?? thanks

 

they make unleaded racegas

use it or make your own, xylene owns

 

I never had a problem with leaded gas. It says 'extended use' which I guess is kind of up to your own descrection to define that.

Every day hundreds of people use leaded gas through their TIAL's

 

if you use it only on track days i dont think thats "extended use"

 

my 44m tial i just bought says its for both leaded and unleaded fuels.

 

gaysex, unless you just purchased a new wastegate for the B16 then it's a SSAUTO knock off wastegate.....? and in any case, I'd have to agree that just a night at the track shouldn't hurt anything.

 

ugh, i never ran the ssauto.

i dynoed with a 38mm REAL tial, and its too small, my 44mm REAL TIAL is on the way. thanks for coming

this is the one i bought

pay attention moron, he swapped it out because it didnt work right the night before the dyno.

 

i have been using the same tial 38mm gate for over 2 years, and have had no issues, on race or pump, i did not ask for anything different
