Tial or Deltagate

[samandw]

I'm trying to find a replacement for my piece of junk ATR wastegate. Can anyone tell me the pro's/con's of the Tial 38mm/Deltagate II/Deltagate evolution? Will they all be a bolt-on replacement onto my ATR headers?

Thanks:biggrin:

I choose the Tail, looks good and should be fine for the horsepower level it looks like you are at.

I was kinda leaning towards the Tial, but I don't know if it's a bolt on. . .is it?

 

[SGRIM]

Yes bolts right in place of the ATR unit, that is what I had to replace too!

I used them all, and I would have say that the Tial is the best.

Tial Hands Down!!!!!!!!


turbo magazine quote, "Tial products are so good you really should buy 2, one for the car,
and one for the wall." When I read about tial in the 90's they were on many lemans n lmp cars
which got my attention

Really? The Tial will fit right in place of the ATR one? Awesome! I thought only the Turbonetics evolution would fit but now i'll get a Tial for sure. Thanks!

I vote for a Tial. I have one and would not go back to my deltagate.

i vote for tial too

Why go with the Tial over the Deltagate or Evolution? What is different and/or better?

i have the evolution and i like it, i didnt think the tial was bolt on....maybe the 38mm but not the 44mm

Yes, unless flanges of the Tial models have changed again since 2006, that is true. The 38mm bolts up, the other Tials do not. I'd be concerned trying to run low boost with a very big turbo with the 38, but my intent was to run very high boost with a pretty big turbo, so I slapped a 38 on S2 ATRs with no flange change.

Tial All The Way

I'm running a tial 38mm with the ATR external downpipe. I'm significantly above the recommended HP for this gate and have had zero problems controlling boost.

wastegate size has NOTHING to do with HP ratings

 

[d90dan]

If a 38mm is rated at 450 hp (example) and a 44mm is rated at a higher hp, then where does the increased hp rating come from?

to put this simple, we have a tractor puller making god knows how much HP with a tripple turbo set up running 220psi of boost and using ONE 38mm wastegate.

only thing that matters when it comes to wastegates is flow, the lower boost levels you run, the larger the wastegate you need - running 1000 hp on a 2.0L for instance doesn't leave alot of exhaust gas that needs to be sent through the wastegate, so a 38mm would work in this situation....now we take a V8 with a GT45R that runs 6psi of boost, this application would need a 60mm wastegate to vacate large amount the exhaust gas that isnt needed to spin the turbo at 6psi

this is why we rate our 60mm wastegate at 330 CFM @ 1psi differential pressure

rating a wastegate for HP is complete horse ****

Interesting. That makes much more sense then what I've been told about the HP ratings vs. gate diameter.

What is the 38mm CFM @ 1psi ∆P?

Thanks for the excellent post, how about some more???

YES TIAL is great stuff!

The more posting you do the better off our board will be.
