    Well, missed out on a set of SVO heads for a decent price, so I did the next best thing and purchased a tick flow plenum. OK, I know it's only a worth a few hp, but have to say that my first impression is that it goes well with the improved breathing of my NPI heads that have the PI cams and PI intake. I'll also have it when I eventually do get a set of heads. It's quite a bit higher than the stocker and it's a tough fit with the aftermarket TB tube. I'll have to revisit it to see if I can get it to fit better.

    Snapped a few pics going in....FWIW, it's the powder coated silver version.

    Yes, but only for now. I do plan on getting a matching TB in 70 or 75mm size soon.

    Congrats on your new Trick Flow plenum! :thumb:
    You should get yourself a 70mm or 75mm throttle body to match your
    new plenum you will notice better throttle responce with one and
    add more airflow too.
    I wouldn't put out all the money for the SVO cylinder heads even if you
    are getting a deal because their are other routes to take with the
    PI cylinder heads that will outflow the SVO cylinder heads unported.
    Good luck though..

    Yea you can get an PI head to outflow the SVO heads that aren't ported. .but thats like me saying i can get a set of ported NPI head to outflow stock PI heads... anything is possible, but why spend $500 on stock PI heads then $1000+ on porting to barely outflow the SVO cylinder heads. Especially if your getting them for a GOOD deal.. say $1200. thats atleast $300 cheaper than ported PI heads, and you can still port the SVO heads and outflow the ported PI heads...

    just doesn't make sense to me from a cost point of view. I know if i coulda got my heads on my ported SVO heads i have in storage, they would be on my current setup and i'd probly be making 100rwhp more than what i am right now on the same boost.

    You have a point but,a ported and polished set of PI heads will in most cases that I have seen cost
    you less than SVO heads ported or not.Don't get me wrong the SVO heads flow very well but,they will cost you
    more in the end.If it were me I would call Scott at VT and enquire about their stage three ported heads.

    I agree. .but if your looking for the most HP out of a 2v Set of heads, then the P&P SVO heads are the only way to go. and i've seen 4 sets of SVO heads go for less than $1300 lately. And the fact that stock SVO heads outflow stage 1 P&P PI heads makes them worth the extra money IMO.

    The SVO heads are the best we can get and when ported by the right people can flow @280cfm (race port) and that can't be done by a PI head even with a st3 race port but cost is always an issue... I was on the path to buying some SVO heads when i came across my VT st 2 PI's at a great price so i had to jump on them. If i was going to be building a all out power hungry car then i would have stuck with the goal of getting the SVO's and sending them to Jim at Renegade but this is just a street cruiser and cost won out.

    Now if i ever build another 2V it will be a BigBore topped with SVO heads for sure.

    Why yes it is (bright) atlantic blue. Thanks for asking. Here's a recent one taken at the track getting cooled down before the runs of the day. Man, you guys are making me feel even worse for missing out on those SVO heads. They sound like the real deal. Urrrgh.

    BAB's are a sexy color...

    yes they are the real deal...anytime you can get them at a good price you should jump on them. I doubt an aftermarket company will come out with anything better and if one does it would probably be Trick Flow and they would most likely copy the SVO design.

    well i hope Trick flow would make some heads for our cars b/c i would buy them if i had the money.

    the only thing i don't like about the svo heads is that they use the npi ports and then that means that you can't use any good intakes unless you shit rig a pi intake to it. I hope that if trick flow does make them i hope they use the pi ports that will match up with that super sweet trick flow intake :)

    do the SVO heads bump up the compression on our NPI motors like the PI do?

    The SVO Intake fits as does a Blower for NPI heads...KB on SVO heads = not bad combo...

    also you can have the SVO heads port matched to work with a Bullit Intake etc...

    No they have a large combustion chamber like the NPI so compression stays the same.

    O i forgot about the kb

    That is a good very good option....
    I would say a bullit or pi and the matching b/c the svo intake is almost impossible to find.....i haven't found one yet :( but o well i'm not really looking.

    So you can match the porting for the pi intake runner? that is a lot of port work

    O one more question, i noticed on the middle pic that the iac hole is smaller on the trick flow one.....does that mean the rev. thing is fixed and it rev's down faster like a 5.0 or is it still painfully slow coming down?

    Unfortunately, still painful. I didn't reset the puter after changing, so I don't know if that would make any difference or not.
