[smokintalon08]

Hi, i'm new on.. i usually post under the turbo mods.. but.. i decided to purchase a gt.. it is a 98 gt. it came with a cold intake, and 3.73 gears, and off road x pipe. I just purchased and put on a set of trick flo heads.. and got a 63mm throtle body.. and bout how much hp do you think i'm crankin out. ohh and i put a stedda shift kit in, and a king cobra clutch.

Trick Flow heads with a stock intake? Waste!
O/R x-pipe without headers or mufflers? Waste!
Steeda shift kit with a King cobra clutch? Priceless!

Troll!

LOL@ Hiflo

me thinks your getting to miss out on some power if your not getting your self I/H/E for your car probbly only getting few extra horse power cause its still trying to get enough air moving.

heres what you should do...if you want to get max power from those heads you have to get an intake and headers or you totally wasted a chunk of money, id go with a throttle body too, and after you do all that id say youd put around 350 to the wheels....rough guess dont know much about those OHC engines

I was just about to say that... WTF? Also Steeda makes shift kits? And a clutch for a car with a shift kit? Ok...

LMAO They make trolls? Yeah, as soon as I read this thread I was thinking to myself "Trick Flow heads? on a 98 GT?" Oh, and it's also good to know that you can get a king cobra clutch for an automatic. I'm thinking of getting one now for my automatic, but only after I replace my CV joints.

With That little throttle body, And the Xpipe you are right at 265-270 HP on that 98GT (mabey less). With those heads you may get another 10 HP to that..But I doubt it.
You really cannot get any HP from The 98 4.6's with heads alone. You must redo the Pistons, injectors, Mass air meter, and a &70-75mm throttle body. Unless you get a supercharger kit....lol
Just look at my list on my 98 below.........

BTW-Cold air intake..is just fancier hot air...it isn't any cooler than a Filter charger kit, just more expensive......
