So I pick up some ART pipes for my 07 HR. I have a lot of suspension work but the engine is basically stock besides an intake.

What kinda gains can I expect with these ART pipes with a stock exhaust and a tune? Would also having a Motordyne XYZ Pipe make a huge difference ?

I couldn't really find a clear answer on gains with a HR motor. Does anyone else have this setup?

 

somewhere in the neighborhood of 15-20 with a tune.
the oem cats and y are a big restriction. but don't go expecting gobs of power. best way to describe tp and tune is better driveability and the car feels more responsive.

 

Sounds good, thank u

 

i gained 17 whp on my hr on a mustang dyno, you will lose some torque though

takeda intakes, art, tdx2, and tune

 

My 07 hr automatic , dynoed at 272 whp with art pipes as my only mod . This was after I got the car tuned with uprev, before tune I felt no increase in power . I thought art pipes were designed to increase not lose torque

 

272? That's it. Couple questions:

What's a stock HR pushing? whp ?
I have some 600cc injectors from a old DE build, would putting them in help me out any after a tune? With a intake, ART pipe, Y-pipe setup (if not I'll just sell them).

 

Never mind guys I got the stock HR numbers, just not use to those low numbers. There like what, 254 stock or something. My DE has supercharged with a old Procharger. I got about 380ish on it.

I was hoping I could get close to 290ish on a decent budget with my intake, ART pipes, Y-pipe (stock muffler) and a Uprev tune. It's not looking like it tho

 

i was 286, see what i had in previous post below. not to mention, mustang dyno which are lower than dynojet

 

I'm sure you could get to 300 whp by adding a good exhaust to that list , I'm going with a supercharger kit , probably the stillen , which is basically the vortec kit for the hr. I'm getting tired of having to put my head down when I come up on a stang 5.0 or a camaro ss lol

 

I've been eyeballing that same SC, maybe some day

 

It's got just the amount of h.p I'm looking for , I will be happy with 330 whp for a long time , I do wish the kit was a lil cheaper , best price quote I got so far is $6300.

 

What mods do u have Travlee?

 

i have since sold the car, but it had (the stuff that you are interested in). for a full list of them, check out my profile.

Takeda intakes
art pipes
tdx2
uprev tuned

 

330 whp? Did you typo or is this the sad truth?

 

haha , the kit is rated at 450 crank h.p , which is about 377 whp. When I get the kit I'm gonna see if I can get it tuned to put out 333 whp which is about 400 crank h.p . My reason for this would be to put less stress on the engine .
