cam question
 
Ok, so i went out and just paid for a set of PI cams out of an 04 gt. and wanted to know the realistic gains i will see. I havn't found a good PI intake (yet) don't have the money for one right now. I saw this deal and jumped on it. its the cams and cam bolts. do i need anything else?? and with just these will i get noticeable gains, or do i need the intake first??

Have you researched to see if you need a cam gear kit? If you have the Windsor engine your stock cams gears are welded on the cams, so look into that. I'm not sure about your year, but i had to get the gear kit for my 2000. Look into upgrading your springs too, not sure about that either. Not sure about the gains, but if you are "upgrading" then i would think so. Find someone that has done the swap already and get your car on a dyno and you will find out for sure. Get the PI intake when you get a chance.

i have heard somewhere around 15rwhp for the cams, but i think that is probably high. From what i heard i don't need to change the springs, but will it help if i did (probably) and i really don't think i need the cam gear kit, from all the sites i read how to do it they never say anything about it..

Its the other way around windsor motors have the bolt on cam gears. The romeo motors have pressed on cam gears. If you had to buy cam gears then you have a romeo motor.

I'm not exactly sure what you will need other than most likely a cam gear set which will run you around 80-100 bucks. I don't think the lift or duration on the factory pi cam will be enough of a difference to upgrade to stronger valve springs. I've never seen anyone buy factory pi cams and put them in. Everyone buys aftermarket cams like comp and vt. Cams are a big job and expensive if you don't do it yourself. If you do it yourself, take your time, make time for breaks where you can walk away for a while, although the biggest pain by far is the valve springs which you may not have to change.

You'll see a slight bump in performance from the larger lift.
Also, Romeos have bolt on gears, not the Windsors. That's why every truck engine has it that way since all most trucks have the Windsor version. However, you don't need to worry since you have the Romeo engine since you are pre 99.
Lastly, you'll need springs since the stock springs were desgined for lower lift. Hope you picked up the PI springs too...

yeah i thought the windor had the pressed/welded on gears. Yellowstang you had it backwards. Yeah i would go ahead and replace the springs while your at it.

yellowstang99 10-09-2007 09:56 PM

Hmmmm....If that is the case, my vin is off. My vin indicates I have a romeo motor but when I did my cams i had pressed on cam gears

bassman97 10-10-2007 08:03 AM

Windsors appeared only in 99 & 00 mainly and since I'm assuming yours is a 99, then that explains why you had the pressed on gears. Also, don't go by the vin since if that was the case, I'd have a Windsor engine in my 03, which I don't. Easiest way to tell is by valve cover bolts (11=Romeo, 13=Windsor).

ok, so how much will it be to get new gaskets??? and i have found the pi springs if i need them...

ohh also any guestuments about gains?? I am currently looking/talking to a guy with a pi intake to get even better gains out of it...

also just brain storming, would it be of better benifits to try and locate a bullett intake??

bassman97 10-10-2007 04:42 PM

Yes, the Bullitt is a great intake so if you can, get it. However, for that or the PI intake, pick up a set of PI-NPI adpators to take full advantage of them since remember, the ports are different and though they'll bolt up w/o adaptors, the ports will be mis-matched, costing power.

SxyXc 10-10-2007 07:24 PM

how much are the adapters and where can you get them??

bassman97 10-10-2007 07:50 PM

HPS has them for $85.

SxyXc 10-10-2007 08:02 PM

ok thanks.

umm if i do try to find a bullett intake, how much if any gains will i make over a pi. if i remember correctly that is one of the things they changed for the bullet, but i really can't remember all that much about it. like whats diff about it... please enlighten me if i am remembering correctly about the bullett intake

bassman97 10-10-2007 08:29 PM

Basically, you'll get a bit better on the top end but you'll get a better overall power/torque curve (better area under the curve).
