Well, I just got back from dynoing my car today. I was pretty happy with my results.
I first dynoed the car as it sat with the stock pulley, intake, and 3" header back exhaust.




Here is the 1st pull Dyno Sheet:

--------208hp 186tq--------



I then took the car off the dyno and installed the Bosch 110 Sport BPV and the ZPI 9lb Pulley, and a Megan Racing Boost Gauge (Just cause I ended up doing it) (Pics of that to come later).
Here is the 2nd Pull Dyno with the New BPV and the New Pulley:

--------227hp 197tq--------



Here is a sheet of the two best pulls on eachother:

Nice! can't beat that for the price

Those headers are your bottleneck. Good numbers!

Nick06tC

Nice numbers, I am going to order the same i think

Here's a video of the second pull. Please right click, save as. This is being hosted courtesy of my car club.

go trevor kick butt! can't wait to see it next time we're at the same place

Munch

Sweet base run with the exhaust and homemade intake. Get a header on that thing and you'll make even more power

nice numbers

Awesome! I've been running the ZPI pulley for about 3 weeks now.. no problems.. such a quick and cheap way to pick up some horsepower Have you been able to check the boost level changes on the boost gauge?

HighlanderMac

Yeah, I am running 9 lbs, sometimes I hit around 9.5, all depending on what RPM I manage to take it too.. lol.. I cant wait to get some headers on her, hope to be close to 250 with some headers.

i heard getting aftermarket pulleys change the engine timing which isnt good 4 the motor... any truth to this?

the415_Dallas

you're thinking about cam gears which can advance or retard the cam timing. that's not the same thing as a boost pulley. the pulley trevor installed today was a smaller pulley on the sc to increase boost.

what an easy install trevor. that impact worked wonders.

HighlanderMac

Hahahah, Yeah, no kidding... time to get me one.

tcholic

wow very impressive #'s i cant wait to put the s/c on mine

Get an emanage ultimate and work on that a/f and bump up the rev limiter while your at it. Still looks like you can make some more power.

tikbhoy

+1 for the s/c

congrats on the dyno

You are running lean! Get that tunned asap.

TurboCustomz

Its not lean. With the progressive nature of a S/C, that a/f graph actually looks really good. I don't think I would want to lean it out much more then that on pump gas, but it looks really nice. I'd say its safe right where it is.

I suppose, but without an intercooler I think we need the extra fuel to keep the intake temps cooler. This was a big issue on my trd supercharged matrix. With past superchargers, TRD would set the tune rich to compensate for not having an intercooler.
I would like to know what the TRD a/f ratio is supposed to be. The use of an intake leaned it out a bit on the Matrix.... along with additonal tunning to what was considered a "safe" a/f... resulted in toasted cats and in one case a blown engine. If TRD says the a/f should be a certain ratio, than thats what everyone should strive for.
Everyone is jumping on the bandwagon with these pulleys and mods without really knowing what the a/f should be.

The AF was basically the same before and after the Pulley...

That is a reason I had the dyno before the pulley then after the pulley, to see what the difference was in the AF, and, well, it is right about the same.

Sooooo... I dunno.
