This landed on my desk today! Thanks to Joe@LeftCoast I'll be evaluating some higher boost levels on the L33/TVS R1900 combo.

See Joe's thread here...https://www.performancetrucks.net/fo...d.php?t=446271

With October's GTG coming up quick I thought it might be nice to see how well this little pulley holds the belt. With NAPA belt K081079HD I should be somewhere in the 11-12lb range, I'd expect.

More coming. Look out East Coast :nunchuk1:

 

It's gonna blow, I'm calling it.

 

I've heard that before, I hope you're wrong is all I can say. Wonder how the 75-shot will feel on top of that?

 

so what pulley and boost are you running now? This is with the TVS1900 right?

 

Yeah, currently making ~165kPa with the 3.2" pulley. I'll be going on the dyno asap to get the timing tables perfect.

 

is it pretty easy to get into boost with the TVS compared to the 112? I am really asking about part throttle..

 

Thanks for testing out the pulley for us. If the Gates K081079HD is too long then you can try a Gates K081074HD, it is a 1/2" shorter. Napa uses the same part number they just drop the K so for them the same belt is Napa 081074HD.

 

Ahhh, thanks Joe, I'll start with the shorter belt. When I called NAPA they didn't tell me this and I can't find it on their website, can you PM me a link perhaps?

Corey, the TVS get's into boost about the same as the 112 did, it just keeps on pulling and pulling.

 

I posted the 8 rib belt sizes above by mistake. Give me a call when you get home this evening and we can get the sizes you need ironed out along with a place to get them.

I am sending you a link for a place to purchase the belts cheap.

 

Humm.... my 3.6" pulley makes 200+++kPa,
