I already have custom plenum(2.2), 70mm tb, ported head, larger valves and t3 cam, npr intercooler would the benefit be that great or should I just stick with current 8v setup? Ive got an entire short block and new forged piston on shelf. I already know about all the work that needs to be done, Id just like to know how much better it truly is from those that are running the hybrid now.

I would stick with the 8v. There have been 8v's over 500hp so unless you are shooting for the moon i would keep trying to improve/optimize what you have. In the end it's more educational and more of an accomplishment than bolting on a 16v head. just my .02

OR Too hybird, or not to hybrid...lol....Ive got time to mull it over so no rush. First order of buisness is getting fender flares on for wider rubber, stock rubber width isnt nearly enough.I tried drag radials, but shouldnt had even bothered, even with the obx first and second gears seem useless without slicks....

We keep having this discussion, lol, its slicks or don't bother, :p

You guys need to step up your game. Bias ply tires is where it's at.

A lot of slicks are bias ply..

Ahh such usefull posts in this thread...bastages...lol...so is it that much 'better' than 8v? Suppose Ill need to see some dyno numbers.

Ok, 16 valve's are easier to make power over an 8 valve, but the complexity for some outweigh the advantages.

Shadow has a 500 whp 8 valve running an HE351 and aprox 35 psi, turboshad uses a 2.4 setup with the same turbo and puts out the same power at 25 ish psi. Both are done up but Shadow's has alot more time, money and R@D into it, also turboshad's car is heavier than Shadow's SC.

Good 8 valve heads are getting harder to find, 2.0/2.4 stuff is easy to find.

I guess it just depends on if you'd rather be near the top of the 8 valve heap, or in the lower-to-middle part of the 16v heap.

It is easier to make power with the 16v, but the inverse of that is it is less of an accomplishment. I still remember how 8valves (username) made ~407whp @ only 23psi on pump 93 with an 8v. To me that is WAY more impressive than the handful of people here who have made 400+whp on the 16v head.

I like the idea of less boost, that translates to lower octane, period. The 16valve must be that much more efficient. I have also heard of ppl getting better mpg...? However I did read no real gain by BadassPerf, that he didnt gain hardly anything going to 16v? Didnt see where he mentioned boost psi..

Usually you pick up mpg.

As for JT, I am sure his 16 valve has less work than his 8 valve, IE the head isn't heavily modified etc.

Vigo

Yeah and he did run the same times with less boost iirc.

There is one user here with a 16v omni that has run 12.6 @7psi. That definitely gives you something to think about.

He went faster but also that car is gutted.

Wow, twelves with 7psi...those Omnis are just the right weight. One other question Ive yet to answer is using 2.2 8v piston, I could easily get the valve notches cut in these new JE's I got but Ive yet to read if anyone has done it(yes looking for easy answer)

Good comparo but I dissagree with your last statement. I would think (just by looking at DJ's build thread) that he has more time and money into his Shadow than I have in the Charger? R&D is prob pretty even.

True on the whole build but engine wise, not as much we would think? There's nothing really special about it, home built header, he did run stock cams at first, home ported head, custom intake. JT is another example, his 16 valve is pretty basic.

Sounds about the same as what I've done with the 8v and the 8v parts are cheaper and easier (for me at least) to come by.

So your head is stock, your exhaust manifold is stock? :eyebrows:

???????? Are you hinting that DJ's is???????

Again not worried about complexity. Surely the 16valve spools sooner with less boost, or is that everyone goes 2.5 adn thats were they get sooner spooling mindset?

No, his is home ported, already said that earlier, you even quoted it, :nod: I was messing around a bit too, I know your stuff is ported.

What I am trying to say, is that to get an 8 valve car running 10's takes a shitload more time, money and effort than a 16 valve. Most 8 valve setups have massively massaged heads, alot more boost etc. Agree to disagree?

how fast your turbo spools will be directly related to how well you plan out your set-up And how much you know about tuning/matching proper components. 16v Should spool same turbo sooner, but depending on who's set-up your comparing to, it's not always the case ;)

Exactly, and 16 valvers are more forgiving in the tuning/finesse department, :p

You only need 300 and something whp to run an 8v k-car into the 10s, and PLENTY of people have made 300+whp with 8v setups. The thing is, they havent had light cars, experience racing, or any real determination to run 10s. Hell, many of them didnt even have slicks. The people (or person?) who DID have those things, ran 10s LOOOOOOOONG ago.
