how much RWHP do 4.6 stangs have? (stock form)

[Road_Runna]

anyone, I know they have 260 at the engine but what about at the wheels.
and is this 260 true for all model 4.6's?

 

[blk2003GT]

260 minus a drivetrain loss of 15% would be 221RWHP. Only 99+ GT's were rated at 260hp.

230 rwhp on a stock 2002 GT http://home.golden.net/~trinity/Dyno/mustdyno1.jpg

 

[03redfiregt]

depending on the car the dyno runs ive seen . our cars usualy put down between 225 and 230 or so stock. And i believe the 260 to be accurate. The cobra and mach are both underrated but i don't think the gts are

 

[decoy562]

Yep, most seem to be around 220-230 rwhp, depending on the car and whether it's a 5-speed or automatic.

 

[StngStr]

231 rwhp here when stock. 2003 4.6L 5 speed.

 

[BlackenedSVT]

Damn. My stock 98GT came factory wit 225flyhp. Wonder what the rwhp would be like 190? yikes...

 

[Solid Snake]

99+ GT: 220-235rwhp
99/01 Cobra: 270-285rwhp
03/04 Cobra: 360-390rwhp
96-98 GT: 180-200rwhp
96-98 Cobra: 255-270rwhp

260hp with a 15% driveline loss is 226 hp

 

[R3VO3VOM]

260hp with a 15% driveline loss is 226 hp

226??? I know its anywhere from 220 to 233 but 260 minus 15% I get????oh saay 221.......not 226

 

[redlined50]

my stock auto 97gt got 190 at the wheels

 

[Blakers01GT]

remember to factor in that a TOTALLY stock GT will put out better numbers then a GT with JUST gears.

 

[redlined50]

i have heard that too.

 

[CottonBurnerz]

my 03 GT dynoed 227 rwhp with 700 miles...

 

[StngStr]

260hp with a 15% driveline loss is 226 hp

narmal math no worky fer yew? 260 - 15% = 221.

 

[robg860]

Yeh..... Take 260x.85 and you get the correct figure 221. Actually very simple math learned in Grad school!!!

 

[Modular2v]

260x.15= 39 260-39=221 But i see gts dyno higher than this...i have also seen that the 96-98 cobras dyno around 240ish

 

[Solid Snake]

Drivetrain loss based on a percentage doesn't sound right to me. So 260 x .15 = 221. What about a 600HP car? Why does it lose more power through the driveline than the 260HP engine?

more power
more friction
more heat
more loss of power

but there have been many debates about this
no real 100% positive answer

Does a Dynojet report...rearwheel HP, or crank HP?
Dynojet supposedly puts in a drivetrain loss correction.
Most posters use the term RWH.
If anyone from Dynojet reads this, feel free to post.
