Come to find out, I have a v1 b trim. Emailed Vortech with numbers. What does anyone know about it? Max boost, rpm, is it a boat ancor? Thx

 

It will make some steam on that 306 if thats your plan, but there are certainly newer/better blowers out there

 

Might be worth it to see if they offer an S-trim upgrade.

 

Yes, I plan on putting it on my 306 in my sig. I do hav 10:1 compression. So planning on Snow meth/water injection kit. Thx for the reply. No its not upgradeable to a s trim. Thats first thing I asked them. They said its around 19yrs old lol. But it is rebuildable and sounds great.
Just don't know what its rated at boost, rpm???

 

b trim is the dead bottom, they cannot be upgraded either.
