power gains from PI headswap and Vt stage 1 cams???

98blackstallion · Jun 15, 2005

ok guys what kinda power gains can I expect from a PI headswap and Vt stage 1 cams on my 98 GT. I have flowmaster 40's dumped and I am soon to have my 4.30 rear gears installed. So if you guys could help it would be appreciated. thanks

hey man,
i would imagine that the power gains will be pretty good.i hope they will be anyway,because my pi head/intake swap is in the process right now.it will be finished friday morning.only thing i used different than you is i am using the stock pi cams right now.
i will let you know how much my swap helped if u'rs isn't finished by friday!!

hey man,
i'd be lying if i told ya.i wanted to go get my car dynoed before i did the swap,but didn't get a chance.if i had to guess at it i'd say around 170-190 maybe.
that damn mod bug keeps biting me.i woke up this morning with the thought of ordering some mac long tubes and matching dr gas x pipe...lol!!

98blackstallion · Jun 16, 2005

those mods should put you in the 250 rwhp range.
do you have an auto or 5sd...auto rob a little more power.
if you add a free flowing upper intake and a good mid pipe to your exhaust you should gain another 15rwhp with the head swap/cam.

90RanGer · Jun 16, 2005

You should be at 275-280rwhp with the head swap and those cams if you have all the little bolt ons. If my cams are ever shipped out I could start on my headswap :/

98blackstallion · Jun 16, 2005

I have a five speed and 280 to the wheels is awesome.

98blackstallion · Jun 16, 2005

yeah i have to catch my friends vehicles now..lol....One has a 97 SVT cobra with a 5 speed, BBK throttle body and thats it i think and says he is pushing 325 or so at the fly and the other friend has a 2001 Ford SVT lightning supercharged with around 385 to the flywheel. SO i am stuck at the bottom again with 225hp. Now I must be able to get atleast 325 flywheel hp outta my car so I can beat the cobra. Oh yeah I will also have 4.30 rear gears in my car.

98blackstallion · Jun 16, 2005

one more question I thought you didnt need a tune with the stage 1's but here lately it seems like you need one so i was only getting the 1's because I didnt need a tune but if i have to get one then how much more HP could i pick up going to a stage 2 VT cams?

.035 is good for the high compression from the swap, .054 is stock.

You'll beat the lightning before you beat the cobra.

98blackstallion · Jun 16, 2005

why do you say that? Is the lightning that much heavier? or whats its problem to the point i would beat it before the cobra.

It is an F-150 remember?

I've seen cobras run sub 14.0 stock. IF your friend can drive good he'll beat the cobra.
