Performance mods questions

[MikEy]

So what do you guys think about SLP?
In the future im thinking about going with SLP Longtubes/HFC, Powerflo exhaust.
All of these parts say that they are easy/bolt on installation so hopefully i can save some money on that.

some more questions...
What do you think about the SLP custom tuned predator? to go with these or just save the money and go with the regular predator?

What the hell is an underdrive pulley?? and are those performance increases real? How hard is the install?marylandspeed.com/slp-harmonic-balanceunderdrive-pulley-with-belt-2005-hemi-charger-magnum-300c-57-61l-slp-100235b-p-2206.html

Is a ported TB worth it? I have read a lot on these and always seems like mixed reviews. What do YOU think? Which is the best company? (BT, Moes, ModernMuscle, CNC, etc)

Let me know what you think and what company you plan to buy these type of mods from or not buy and why (Exhaust, headers/HFC, Underdrive Pulley, Tuner(mostly likely diablo), and TB).

This ended up a little longer than i expected...

Some things you need to know, from someone who did them.
Any shop will charge you a minimum 500 labor for whatever headers you go with. The reason is because to remove the stock ex mani's, you either need to disconnect the motor mounts to life the engine a couple inches, or, pull the heads. There is just so little room in the engine compartment to get to the exhaust studs.
Underdrive pulley spins everything driven by the serpentine belt slower. That means water pump, alternator, ac compressor, everything. Because the engine is working less (Turns the pulleys slower) it has more power going to the trans, thus more power. This is fine unless in a very hot environment. The power is noticable.
Order a regular predator, and do a cmr or dyno tune with it when your performance mods are done.
Here is what you should do.
Order your underdrive pulley, headers, and a cam (and a cam install kit). You will also need head gaskets, ex mani gaskets, stuff for an oil change, and a couple gallons of coolant from dodge. Then you pay Jack 500 bucks and give him a hand as we replace everything. Will take a weekend. If you can swing it, buy the heads too.

Do you have the underdrive pulley?
Is it easy to install?

[tbydaytona40]

install is pretty easy. No I dont have one

[MikEy]

I think im going to start off with the easy install stuff first.
CAI, Predator, Underdrive Pulley, Ported TB, 180 T-stat, Exhaust.

Are there any places that you can get a tune here in Utah

[tbydaytona40]

Skip the ported tb

[MikEy]

I would check out API

[RT722]

How come you say skip the ported TB? Is it really not worth it?

[tbydaytona40]

not worth it.

[tbydaytona40]

If your cam and engine cannot process more air flow, and if your exhaust system will not let a great air flow egree, having more air going in doesnt do anything for you.

[RT722]

Ya that makes sense. With the money you could just put it toward a cam. What cam do you recommend. I may have to take you up on that offer to get it installed one day

[MikEy]

I knew about the ported TB, thats why i asked the question before.
Always 50/50 reviews but no real hard evidence that it actually did anything

[tbydaytona40]

As far as cams go, the biggest thing 5.7 owners need to decide is, do you want to retain MDS? Also, are you doing heads? Some of the more highly aggresive cams can actually suffer on stock heads and exhaust systems. I recommend as far as companies Inertia Motorsports. Very good stuff. Stu is a pro. You have to get contact info on LXForums where he is a vendor.

If your gonna do the TB, you might as well get the Turbonater.
