but his isnt ported.........

 

Got numbers........after a long 3-1/2 trip to the Long Island area...

as I drove it with pump gas, canned tune from RWTD (tuner at Mustang Magic thought my canned tunes were excellent FYI), 2.93" pulley: 445 rwhp...

Change over to the 2.76" pulley, pump gas: 461 rwhp, 444 torque
Race fuel added, 465 rwhp, 453 torque

Stock TB hurting me a little......but, I'm happy overall! ....long day as I logged over 1,000 miles in less then 24 hours as I came home from vacation on Friday.......

 

I WIN!!

 

Great numbers! Time to get a BilletFlow TB/Plenum combo

 

Thanks!! Yea, gonna have to look into it, TB could pick-up 15 hp....after 5800-5900 Eaton just making noise!!

 

Does anyone know if you need a tune when you install a new tb/plenum?

 

imo i say no cause you are not gaining lots of power out of the 2 so it wouldnt make sense to spend 300+ for small gains.

 

i'd just get the A/F checked on a dyno... by swapping the TB, you'll get more air

 

According to my tuner, YES, you will need to get a new tune if you swap the TB....

 

wow i am still not understanding that, when i had my stock tb with my kenne bell then put a 75mm tb on their i felt a lil difference in hp but nothing with the tune, she ran beautiful.
