V-2 S-Trim---how much boost/hp?

[StngStr]

Hey guys,

This s-trim I have sitting in the garage has what appears to be a 3.1" pulley on it. I also have another pulley that is 3.5". I'm assuming that the 3.5" pulley was stock. How many lbs do you think I'll be making with the 3.1" pulley that is on it?

Setup:

1996 Cobra
Vortech V-2 S-trim 3.125" pulley
42 lb injectors
80mm Pro-M
Vortech race by-pass
Anderson powerpipe
255 lph in-tank Walbro
march SFI crank pulley
o/r H pipe
flowmaster catback

What kind of power should I expect from this combo?

some pretty good numbers should come from it. probably like 8-9 lbs. tops...

I have a 3.12 pulley and see 15lbs on a t trim, and when my buddy had it on his s trim he seen 13 to 14lbs depending on the weather.

3.6 is the stock size, and the 3.5 you have should actually be 3.48. If its not intercooled I would think it should be around 10lbs with the 3.48. Don't know about the 3.12.

My 99 gt has a SQ-trim with a 3.12'' pulley and its seeing 10lbs of boost.

Really?? Damn, do you have an intercooler? That boost seems very low with that small of a pulley. You should probably be around 12-13lbs. I've got around 9lbs with my stock 3.6" pulley and MPH boost pipe.

I agree thats way low for that pulley, must have bell slipage.

 

[StngStr]

how much power w/15 lbs and those mods?

 

[sunburned]

You mean 15psi and a mean green's T-trim? He must be making over 500 easy.

Don't quote me but 3.125 pulley on a cobra must be running 12-14 psi and will probably make 450-475hp, which could possibly be too much power for your stock internals. Check out www.modularpowerhouse.com , they are pros with centri blowers on modular motors.
