How much boost is too much?

Brutal87 · 12-12-2005, 06:11 AM

I have a Vortech V1 charger thats putting out 6psi right now.

I would like to change the crank pulley & the blower pulley. What size can I goto? How much boost can I get out of this charger without killing it?

Also I planned to upgrade to 42lb injectors, larger mass air & 75mm T/B.

edit: What is this charger called? A-Trim?? S-Trim?? & will pulleys from other Vortechs work as long as they are the same rib?

Thanks
Carl

I believe it would a S trim.

Depending on your tune you could go up to 14 psi

How old is the blower? A-trim's also said V1 on the housing. I spun an A up to 13psi, but it wasn't very efficient. Went to a T-trim from there and the same pulley setup made 17#'s. T-trim=much more efficiency!

If it came with the 5-6# setup than it's either a A or SC-trim. The SC is the old S-trim, so they can be spun pretty high. So, we just need to know a little more info on the head unit.

I don't know about that part number, but the V1 could be an A-trim or an S-trim. Depends on the compressor wheel. If it has curved edges, it's an S-trim. Max around 14-15 psi. THe A-trim: about 9-10 psi. After that, they are generating more heat & you're better off upgrading the cam, etc.. to take the extra air.

I run my s trim to pretty much max capacity and its around 14 or 15

A-Trim huh??

Also I'm runnin a 3.33 charger pulley. What pulley sizes do you recommend to get 10psi?

Thanks guys.. You have been a huge help..

A 6.87 crank and a 3.33 upper will make 10psi on a smaller combo heads etc. the s trim will make 18 psi and is capable of about 610 to the tires through a stick depending on combo of course. I realy like the s trims for a street strip car that is driven on a regular basis.

I believe that's the SC trim. Nice blower either way. Take it to 10 at the very least.
