I am thinking of adding one or both,
if I can get some feed back on either, an after market heat exchanger,
or a larger water pump pulley that is designed to take some drag off the engine,
I already have all this other stuff listed below so if anyone has put either a heat exchanger or larger water pump pulley on I would like to hear what
REAL GAINS,,, you obtained from the item,
RPM OUTLET give no horse power numbers for the Motoblue heat exchanger,
however they do say the 22% underdrive water pump pulley gives 4.5 HP and 6.1 Lbs of torque.

I have currently:
2.80 pulley
predator tuned
all billet idlers
Magnaflow X-pipe
Accufab throttlebody
cold air
95MM meter

talk to me?

I would recommend the Fluidyne Heat Exchanger and also the Fluidyne Radiator, as the Cast Iron blocks in the Cobras hold heat!
Just my .02!:rotf:

I haven't had the items installed yet, and no dyno, but as soon as I find out I'll post some info on it!
I'd email Tony at the need-4-speed, he's the one that helped me with all the info and power gains!
