Granatelli 103mm TB anyone ?

Looking at these TB they appear to look good but skeptical? Says good for 25lbs of boost but when i search the forum I find very little relating to them...anyone have any first hand experience?

I know some people here don’t care abt price. But I believe you get what you pay for. At that price I’d be skeptical. I have my Nick Williams that will
Be installed during my next round of mods. They are pricey but only heard good things. So at that price I guess you could try and see how it works.

They make a billet version for $650. The one in the link is the cast version, that’s why it’s cheaper. I ordered one from Granatelli 2 weeks ago. I’ll let you know how it works out. Supposed to ship tomorrow.

I ended up upgrading to the billet version because of the backorder on the cast one. installed it 2 days ago. all is good so far. I have a tune set up for Wednesday. we will see how it handles all the boost.

At that price you're right inline with NW. Why not use tried and proven? Just wondering.

Since they were back ordered they gave me a deal on the billet one. I only paid $450 for a boosted 103 from them. NW booted is what? $900 so still way under.
If it works out, Great. We will all have another option choose from. I talked to senior Granatelli and he uses one on their own 2000 hp car with no problems. Time will tell.
