I should be getting my TVS sometime soon, and I'm wanting to shift at around 6100-6200rpm.. I'm just worried the TVS will max out?

I've bought the tvs of MCN5, and installed is a 2.8 pulley.. He's sending me a 3.1 that I should be using intially until I build up my engine...

any ideas of ratio calculations?

 

You won't max out anything at that low of an rpm.

 

any idea what the max would be? Right now I've got my shift points set at 6500rpm, the truck loves pulling all the way up till there.. I was hoping it would with the tvs, but just worried something might go wrong

 

Stock cam, springs? I wouldn't worry about the TVS, all of the graphs I've seen (including mine) show the HP keep rising all the way, never falling off.

 

mast L92, 220/234 .570/.588 116 on PRC doubles.

I'm sure i can keep pushing it, but just want to know it's limit.. IATs are around 70*C over summer.

 

Spin the szhitz out of it and have fun.. Perhaps someone else who has run boost on a stock bottom end can add some input but I think you'll be fine with the 2.8 pulley and just over 10lbs of boost with the right tune. I didn't tighten the 2.8 up prior to placing it in the box so you'll need to tighten it up if you decide to leave it on there.

 

People are spinning the larger ones much faster to get their 18psi so I wouldn't sweat it one bit, but if you really wanna know PM brian but he'll tell you the same thing.

 

on a side note, if u wanna sell the 3.1, let me know!

 

Are you running an overdrive on the crank pulley?

 

i am running a 2.8 on my tvs1900 to 6400 with stock crank pulley...no issues and 9psi
