Cooling and charging. On my 4.6 2V, I noticed insufficient charging output from the alternator (I had to boost the idle speed to 800+ RPM, stock was 560 RPM) and the "gain"in hp wasn't significant. The smaller diameter crank pulley was reported to be insufficient in dampening the vibrations which can damage the oil pump gears.

I went back to stock pulleys and didn't even notice a change in performance.

 

Doesn't the RoushCharger still covered under warranty?

 

The Roushcharger does cover warranties,but I think the Roushcharger has a unreasonable price for the power gains that it makes,and the fact that the warranty is kept is not a excuse for the outrageous price.

I have seen 8hp gains from the BBK TB,have heard positive things about the Motoblue UDP's,and Stage 3 Comp Cams have a mild idle,as shown in this example:When we picked up our 2005 Mustang GT back in late 2004 we knew it had tons of potential. Only through the detailed and intense R&D that we perform do you really find out what works and what does not. We have tested about every part on the market and not often is it worth writing about. With the introduction of Comp Cams 3 valve camshafts we knew it was time to put yet another part to the test. We opted for what Comp calls Stage 3 cams. These cams are VERY mild as far as we are concerned and should be called Stage 1. For various reason that we won't go into here this is the largest cam you will find Comp selling for a while. They idle mild, drive like stock, yet add a TON of power.

 

Do the headers not void warranty? Because I was under the impression that any set of longtubes would.

Also does anyone have a dyno graph of how much power can be expected from the stage 1 or 2 comp cams with springs?

 

Just because one mod give you x hp and another gives you y hp it does not mean you will get x+y=z hp. Also, the Roush charger and certain others DO NOT void your warranty not sure which others I think Ford Racing and possiblly Saleen.

 

Good point about hp gains from 2 or more mods together Greywolf. Which other supercharger does not void warranties besides the Roush one? I know the Fordracing one does void it,cuz it is made by Whipple,and sold by Fordracing,but I am not sure about the Saleen though.

 

I'm surprised superchargers don't void warranties. Someone on the Crown Vic board blew out the 4R70W after he ran a 9 psi AED kit (Eaton roots blower) and had the 4R70W replaced under warranty w/o any problems.

Meanwhile, some dealers will blame the color of the shift **** you bought for causing valve stem seal leakage and try to void the warranty.

 

Superchargers don't void warranties? No way!

 

If you look at my mods I have most of what you are looking to do...
I don't have cams... and I don't have a TB.
I did however opt for the Shorty JBA's and got the Livernois Motorsports Port and polish job on my heads...
I'm making 300 at the tires and roughly 365-370 at the crank... I think the combination of the cams and long tubes will get you there but you'll most likely have to do the heads too...
Oh and my $.02... don't waste your money on the TB... Stock flows more than you need for 400HP and the Coils won't help much either....
Save your money for the heads...

 

I will add the mods that I listed besides cams first,dyno it,and see where I am rwhp wise(I am shooting for 310-315rwhp w/o cams),and if I don't even get close to reaching my rwhp goal with cams,which is 340-350rwhp,then heads might be an option.

Also,I found out that you have approximately 352hp at the crank True HP. I was expecting that with the mods u have,you should be pushing 370-375 crankshaft hp.Out of all your mods,you only got 52hp over stock hp.

Did you dyno your car on a Mustang Dyno?

 

Like I said. Maybe he will listen to you. Either way, it's his money to waste.

 

Just like that you have 400HP.

 

Yeah,your right,I won't get the TB cuz they made exacty 400 crankshaft hp w/o the TB on Brenspeed,but when they put in on,it made 408 crankshaft hp,so the TB would not be needed to make 400hp then. Instead of the TB, I will get a meizere electric water pump.

 

Only some they have them set for low boost so hp is only around 425. I think the Roush and the Saleen have warranties only if you don't up the psi which would give you more hp.

 

Like I said though,just cuz a supercharger has a warranty does not mean I will buy it. Here are the 2 reasons why I won't buy a warrantied supercharger:
1.They usually have a outrageous price($5,500+ a.k.a Saleen & Roush)
2.The hp gains they make aren't very large over stock(+100-125hp a.k.a Roush & Saleen) compared to non-warrantied superchargers and the hp they make can pretty easily be made with bolt-ons for a much better price.

 

If you want 400 HP, you'll need to get a blower. I say this because if you are asking this question, than you have little to no experience with these cars.


DO NOT BUY A THROTTLE BODY OR GRANTELLI COPS....They are both pretty much useless.

If you want the most out of your Stang, save that money and get a blower.

As far as warranty goes, you will never reach those numbers and keep your warranty.

You can't even flash the PCM and keep the warranty. So there goes a CAI, LT's, Cams, Heads, Off Road Mid Pipe, Gears, pretty much everything.

Get a blower!

And please, please do not put a list in your sig of the mods you want to get, that's pretty sad. Your "proposed" list is bigger than your current list.

 

Where are you getting yor info?????

Are you saying that you can make the same power as me, with only bolt ons? And pretty easily on top of that? Come on, only if a blower is a bolt on...LOL!

It's not going to happen, and you'll spend just as much if not more trying to reach that goal.

I guarantee, that you'll spend more money trying to reach 400 rwhp than I spent on my blower!

 

I meant 400 crankshaft hp. The rwhp I want is 340rwhp. Ok? Also,I know you definitely have 460rwhp with your KB installed so I 99.9% doubt there is any way of matching your hp with every single bolt-on,and with every bolt-on, only someone that is very lucky could hit 400 rwhp. Just my $.02.

 

Sure, but just refer to it as rwhp as hardly anyone will take out their motor just to get the crankshaft numbers. So this way, people can compare their dyno numbers to yours.

340 rwhp, yep, it can be done! You'll need Heads, Cams, Intake, Full Exhaust including long tubes, Electric H2O pump, Charge Motion Delete Plates and that should get your there. If not, F.A.S.T. has a new intake manifold coming out that should get you there!

I have to reiterate that you should not waste your money on the TB or the COP's, as there have been soooo many people before you that tried these mods, all with similar results.

Don't believe everything you read in magazines, and definitely don't believe everything a vendor tells you. Always look for unbiased, real world experiances!

 

I took your advice on the GMS COP's and TB,so my plan to make 340-350rwhp is CAI,Tune,Headers,Water Pump,Cams,Pulleys, & CMDP's.
