Thread: where is my power gains??????

Most of what you have done are supporting mods for a pulley drop. They don't make noticeable power by themselves, but do when you drop the pulley. If you haven't read it yet, go the safely modding your 3800 thread and read up.

you may have gained 15 hp so far but your set up nicely for a 3.4 pulley drop and you will notice the diff

So basically all you've done is a tune and exhaust work...because wires/plugs/t-stat/intake really don't do anything on these cars.

Get the 3.4"...you'll see a huge difference then. Don't think it'll be a damn race car though. You won't get there till you put on an IC and drop to a tiny ass pulley or put a cam or rockers in it and re-tune it.

and make sure you have the rest of your tune up done, fuel filter, fresh engine and tranny oil, all the good stuff

If the coolant temperature sensor is faulty, that would give you some major problems.

But unless you drop a pulley size or get a custom tune, your not going to feel any more gains on the butt-dyno.

explain cammmmmmm.... how does camming get the power gain? I am interested in this information as well. I just had headers put in, and dropped to a 3.5 pulley. I have 104 plugs, CAI,... After all this, It actually feels like my car is slower than it was when i was stock. I have a tuner working on it now, he has tuned it, but my car still feels worse than stock. I am going to drop to a 3.4 and get a smaller 66" SC belt, hope this helps, any other ideas? sorry for the hijacking of this thread, but it is inline with the topic.

If you don't understand how a aftermarket cam makes more power...I suggest reading...its a great tool.

If not...it allows more airflow...since I don't want to get to technical with you...there are these things called valves and rockers that the cam moves...it allows more air...soo...umm, more power.

Well, more air does not always equal more power.. If that were the case, simply adding headers would make a huge power increase. a simple cam could actually decrease the power if not combined with a pulley drop or other adjusted mods. Again, this is from what I have "read". Reading and researching is not my issue, getting some inside information from people that have gone thru this is what i am after. But, thanks for not getting to tech on me..

Tell me how headers are a air ADDING mod?

They are a flow mod...as in exhaust...they get RID of air.

As for your car feeling slower...maybe...but it isn't. The headers/pulley/tune you have has merely shifted your powerband to higher RPM's. You want necksnapping torque? Go back to manifolds.

As for a cam...I had 1.84 Roller Rockers with Ported Manifolds and a 3" DP/U-Bend Delete with a 3.5" pulley and a DHP PCM with other small supporting crap mods...I got rid of all of that for Pacesetter Headers, XP Cam, LS1 TB, 3.2" Pulley, custom tuning...etc. I went from chirping the tires at or around 20 mph to totally annihilating them at 35.

Ok, now this makes perfect sence.... This is probably the case with my setup. so, is there anything I can do to get the "snap neck" feeling into this car? will the drop to the 3.4 pulley and the new belt make much of a difference? any other good ideas?

No...not really. Get more mods. Like a cam...or put meth on it...and get a tiny pulley...like a 3.2"

More Mods will get your TQ back. I know the neck snapping TQ was fun but it makes it a ***** to hook up with. Go to the track and see how much easier it is to hook up and run consistently with headers.
