I can feel the higher power....

[streethorse]

Ok, I just got back from a test drive down the highway after
installing my C&L plenum/70mm frpp TB on my 04 gt. ( only had for 1 month )
On Saturday I had 2 magnaflows welded on. Then, taking the advice of most
stangneters, I ditched my MAC CAI that was on my 99gt and went with a
K&N filter on the OEM setup with the silencer removed , which is awesome.
With these 4 upgrades added at the same time I could really feel a major
kick in the a$$, .... no ??? about it, my guess is about a 20 to 25 hp gain
And Im not finished yet.

I believe that you were able to feel it, I could deffinately feel a slight difference in higher rpm's with my x pipe, but I doubt you got 20-25hp outa the deal. The hardly add anything, and the plenum/TB prob wouldnt be much more than 10hp or so.

 

[scupking]

Yeah, also don’t think you are pushing 20-25hp. I know I also felt a nice SOTP when I had my mac catback installed with the stock H pipe and with a K&N and air silencer removed at higher RPMs. Then I got a MRT-H and felt another jump up on the SOTP meter. I figure I might be 10-15 hp over stock but not 20+, you are probably about the same.

I am sure you did gain something in the SOTP meter but, not 25 rwhp.
Congrats on your new mods and enjoy your car!

Id say 8-10rwhp with pl/tbdy/filter, maybe 2-3rwhp with the magna's, so Id say no more than 12-15rwhp. But, any gain is a +!

 

[streethorse]

Yeah , Im a bit overly optimistic and am overestimating the hp gain, but
anyway its nice to absolutly feel a positive gain. Next mod will be UDP's.
I am now at least faster than stock.

Now just ditch the stock H-pipe with 500 catalytic converters on it.

sadly most of what you were feeling was probly signifigantly improved throttle response. It all adds up though, change out that midpipe and you'll get another surprise for your pants.

The UDPs are going to be minimal SotP gains, but you will notice them under some conditions.
