I cant find anything on changing the oil on my Magnuson TVS1900. I know it doesnt have to be changed for 80,000miles but would like to know. Also whats the max RPM that the SC can run at?
I bet I cant use a TVS1900 on a 7.0L that i want to use when the 6.2L is thru.

 

I think 18k is the limit...you can use it on the 7.0, but it will only make 4-5lbs with the smallest pulley.

 

Allot will depend on the cam and CR of the 7.0, but no matter how you cut it the 1900 is going to be small. Pulley wise you are looking at a 10 OD crank pulley and a 2.7" blower pulley on a 8 rib setup for max boost. I think 2.7 is the smallest, not sure if anyone has a 2.6 for the TVS.

 

I dont think you can physically fit smaller than a 2.7 because of how the pulley bolts to the blower.

 

Ya you may be right, I never took mine down that small so not sure. You would be limited by the location of the 4 bolts.

 

ya ill have to sell the 1900 and get a 2300 then. maby sell the 6.2l with the 1900 to pay for a long block 7.0l

 

old but never found out how to change the oil

 

I am not sure either, kinda curious myself.

 

Remove the snout.
