600 rwhp with GT500 and stock eaton.

[98Snake03]

Is this possible? I am in a debate with a guy, and have seen 580 with an upper and boltons....ports don't count.

So is it possible? With upper and lower with full bolt-ons (no NOS, no meth)

and any proof?

Thanks guys.

George (I think his screen name is 91svtbird or something along those lines) has cracked 600rw with stock longblock/blower. He emailed me the dyno resuts months ago, sorry I don't have them anymore. I'm sure he still does though.

those 5.4 are amazing

with it ported 601 hp 600 torque with a 2.6 upper and 4lb lower dynoed last week in 90 deg weather. my buddy ran 585 with no port and different headders.

I have a customer with a upper/lower, single blade TB and long tubes that put down 606 rwhp & 617 rwtq
Not sure about SAE though

I see no reason it wouldn't. Mine is 561 Add 4lb. Lower with the 160mm TB and Ford GT cams and I would expect around 620hp.

I made 576 rwhp with upper/lower, tune, catback, heat exchanger, still running stock manifolds and cat convertors.

589 rwhp

mine is 589 rwhp and 573 tq on a mustang dyno. 2.6 upper 4# lower 160mm TB, stock exhaust with corsa mufflers and C&L cai.

Did you have to make any modifications for the 160mm tb to fit on the stock eaton? did you notice any improvements with the TB? I know on my old 04 cobra the larger throttle body made a difference on the dyno and seat of the pants.

What kind of cooling mods are needed to get 550-600rwhp???

I have heard the stock cooling system is very good but man the heat soak with my intake and stock boost is crazy and I could not imagine how bad the heat would get from chaning the upper and lower pulleys!

Bigger heat exchanger is a must when running 16+psi thru the stock eaton.

no mods needed for the TB. but had to change to the C&L cai from the JLT carbon to get the new FRPP strutt brace to work.
this thing is now a beast as if the stage two already was not - this is just wicked

Can the stock eaton handle the extreme RPMs and still be dependable with good life expectancy?

Even with the stock boost, the larger intercooler heat exchanger is of great benefit. Especially in warmer climates. Almost completely eliminates the heat soak problem for normal driving.

it is okay for me as i only drive it about 3-4000 miles a year. and i figure once i hit 11.5sec in the 1/4 i will most likely go back to the 3" on top, which will essentially get me back to a stage 2 car with a bit more torque because of the more efficient TB.
