Yep, that car is 4V swapped. Condemnation might have been to harsh a word. Yeah 3Vs can and do make good power but that was never what I argued against.
Here's the world's 1st 7 second 3V: /watch?v=dvWIQcBmWbU
I agree the proof is in the pudding and the evidence shows us a stock cube 4V going 6.0 @ 236 mph in a 2,500 car, making in excess of 2500 rwhp on gasoline. The evidence also shows us that no 3Vs have broken the low 8 second barrier, even in a 25.5 chassis. I was involved with two comparable builds, an 03 Cobra with a 9:1 stock displacement/stock head build and an 08 GT with 9:1 with stock displacement/stock heads....
@LieKiller Actually, Team MMR has one (stock chassis) in the 7s off the top of my head which is way below the 'low 8' barrier that you mention. I didn't mean to stick a hornets nest and definitely no disrespect meant but let me reiterate the point I was making: If I already have a 3valve, why would I go through all the trouble to swap it away when I can make 1000+hp with what i have? Silly really. As far as all the other hairsplitting? I'm taking a break.
Under boost the 4V will offer significant advantages. The most powerful 3V I know of is making about 1100 rwhp, it's a BB/S with ported heads, 88mm turbo, etc. Stock cube 4.6 4Vs are in the 7s in drag radial type setups, 1000 rwhp is actually easy to come by for the 4Vs at stock displacement much less with big bore and bb/s.
@LieKiller Let's say I'm in the game to make 2500hp.. am I going to choose 3valve heads? probably not. Does that mean that I couldn't make 2500hp with them? probably not. has anyone tried? Don't think so. Do you get my point? The POINT is this.. 1000+ hp is not difficult to achieve with 3 valve heads, bottom line and you can't argue that away. If I already have 3valve heads I'm not going to toss them unless I have a REALLY good reason too. (I.E. beyond stock class.)
@SirtubalotTX A 3V will never make 2500 rwhp on gasoline, period. MMR doesn't have a 7 second 3V, Dana Cook's 180+ mph black S197 is 4V swapped. I should have said a 3V hasn't broken the 7 second barrier in a Mustang. The first 3V to make it into the 7s happened about 2 months ago and it was in a fox body FAIRMONT, 7.9 @ 170. 1000 rwhp with enough boost is possible with any decently stout engine, the condemnation is that 4Vs gets there a lot easier.
@LieKiller Has anyone ever tried? lol. This is the MMR 7 second Stang I was talking about:(/watch?v=rnzjYe14u38) I'm not entirely sure but your saying this is 4v swapped? let me know. We're not too far off base LK but I just don't agree with your "condemnation". My original point was 3 valves 'do just fine' and I'm sticking to my guns. Even though they are on their way out, many people still have them and as this video and many other prove, you 'arent hurtin'. hehe
@SirtubalotTX The 3V heads do do well, but 03-04 4Vs do a lot better, and Ford GT/GT500s do better still. Assuming the engines and turbos are otherwise comparable, of course.
@LieKiller I don't disagree with you LK but that's besides the point. Balls to the wall and compared to it's 4v counterparts, 3vs still surprise me on airflow and they are also superior when it comes to airflow 'geometry'. (That's another thread) Bottom line? the point I'm trying to make is you ain't got to fix something that ain't broken and ur running 3v heads? you ain't hurtin'. Only thing I would do is throw in an iron Cobra block under those 3v heads and that is not hard to do.
@SirtubalotTX Not sure what surprises you about 3V airflow, ~230 cfm for stock 3v intake port, ~268 cfm for a stock 03/04 4V intake port, ~315 cfm for a stock GT500 intake port. Airflow geometry? The 3V has a nice raised intake port but the small intake valves more than offset any advantage it has over the 03/04 4V, despite the 03/04 more pronounced short side transition to the valve seat. The GT500 has nice straight shot at the back of the intake valves. But that's overlooking...con't...
@SirtubalotTX ...overlooking the 3Vs biggest weakness, which is the exhaust side. The 3V's I/E ratio leaves a lot to be desired. Take the engine in the vid, I can pretty much guarantee if the same compression and boost level is maintained, and cam specs (including LCs, another big 4V advantage) are chosen wisely that BB/S would pick up a solid 80-90 rwhp at peak and it would build boost more quickly. Simply put, if you're running stock 3V heads you ARE hurtin.
@LieKiller I got you on that LK and I'm not sure it's that easy to quantify the 'disadvantages' on the exhaust port. n/a?, I'll concede the advantages of the 4v but under boost?Won't do it and like I said.. that's another thread. Proof is in the pudding and there are plenty of folks keeping their 3vs and making 1000+ relatively easy. If that's hurtin' in your book, I REALLY need to get my references straight. :)
@SirtubalotTX ...the 08 made 610 rwhp on 16 lbs and 16 degrees through an auto with locked converter, 670 rwhp on 18 lbs and 18 degrees. All on pump 93. The 03 Cobra made 690 rwhp through a TH400 (no lockup obviously) on 16 lbs and 16 degrees. Again, both 283 (.020 over), both 9:1, both running stock heads, both running stock intakes (Mach in the Cobra's case), both running kind of similar cams (222/222 114/114 in the 4V, 229/242 w/ VCT limiters in the 3V), the 4V was worth...
@SirtubalotTX ...80 rwhp over the 3V despite being run with a TH400, which itself probably robbed 30+ rwhp versus the locked converter 4R in the 3V. Oh, and both were running Precision 76s with .96 A/Rs. When everything is kept fairly even keel the 4V offers significant advantages with boost.
@SirtubalotTX I said, "The 3V has a nice raised intake port but the small intake valves more than offset any advantage it has over the 03/04 4V..."
Trying to keep it short and sweet, but to add the small intake valves and their WIDE placement in the combustion chamber is what pretty much kills the 3V versus the tumble port 4V heads. That wide intake valve placement limits valve size and promotes shrouding, impacting airflow. The 3V combustion chamber will also never be as efficient or...
@SirtubalotTX ...as detonation resistant as the 4V chamber, with it's pent roof design and perfectly centered spark plug. The 3V makes solid power, no doubt, but keeping everything on an even keel, or for max effort builds (N/A or power adder) the 4Vs offer a lot more potential.
@HusseFrassin In the u.s. we have 87 octane being the lowest in most states. 89 octane is mid and 93 is USUALLY the highest we can get as pump gas. But I've seen some people calculate it as being like our 93 octane is equivalent to 98 RON or some shit? I'm not sure.. Someone correct me im I'm wrong.
