supercharger boost

[bimmer]

what is the highest boost you can get out of the trd supercharger??
like stock vs. aftermarket pulleys, etc.


are their any other companies that make s/c or turbo kits for the solara?


thanks

5.5 lbs of boost is with the stock pulley. 6.5 boost with an aftermarket 2.75 pulley.


2nd question: nope

Stock is 4psi. If you see anything over it's called manifold backpressure. Aftermarket...safest is 6psi...anything greater...you're kinda playing with fire unless you work with the fuel system.

Only for the 4cyl...Rippmods S/C for the 5S-FE and Turbo Performance kit for the same engine. Nothing for the 2AZ-FE or 1MZ-FE unless you go custom.

how much actual real world (wheel) hp are we looking at at 4 psi............how about at 6.5 psi or however much the 2.75 pulley gets you

i am debating whether or not the s/c is worth the price

thanks

Depends whether you have auto or 5spd.

Auto will get anywhere from 200-210
5spd will get 220-230

[bimmer]

which boost pressure is that?

im looking for the manual tranny

thanks

i'm pretty sure ross is referring to the stock pulley on the s/c

[bimmer]

yeah i am more interested in the 2.75 pulley

what are the wheel hp power numbers on that one?

anybody with dyno sheets

You won't find many guys with manual who have 6psi but I do know a few who have 5 or higher.

Steve (str8pyp) has 5 psi and hit 252whp, 240ft. lbs. torque
More info on his car is available here: http://www.schung07.com/performance.aspx

Most guys are around 240-250 at 5-5.5PSI. I believe Ericsol was seeing the low 240s but now that he has headers, ypipe and a hiflow cat he hit 273.

With simple mods you can see 250fwhp easy on the 5spd. (Exhaust, S-AFC and SC)

You are probably looking at about 240 or greater with the 2.75. With automatic tranny, expect way less than that. I don't recall who has dynosheets with the 2.75 in.

how dangerous is it to run the 2.75 pulley (6psi im guessing) with an s-afc vs. the 5.5psi pulley

dangerous enough that you could potentially blow your knock sensors. (info courtesy of Ryan)

I blew mine with a 2.9" pulley.

You should be safe...but if you're running california 91 octane...you're at a greater risk of blowing your knock sensoers. I'd stick to anything closest to stock size pulley if you don't want to run into greater risks.

A 2.8" pulley will get you 6 psi, so you're looking at around 6.25 psi with a 2.75" pulley. You'll probably be OK with it unless you're in CA and stuck with 91 octane gas. If you don't have an upgraded exhaust system already, that would probably be a good investment, as it would help power and eliminate some backpressure. At that boost level, you'll be right at the safety margin, so anything that will help you prevent detonation is a good thing.

I have a 5.5 psi pulley, and dynoed at 247 fwhp and 236 lb/ft. I have also been having trouble with my #2 knock sensor and will probably have to have it replaced.
