who said 2v sucks!

YouTube - Dave's Livernois Motorsports Built 2V on the Engine Dyno

So about 375 RWHP equivalent, pretty bad ass.

That's enough to keep up with a new camaro or 5.0 with a few bolt ons.

All the people that think 400rwhp is possible in n/a form from a 2v.... If these big shops cant build one, you definitely are not going to. It might "can" happen but shit, i wouldnt sell my house to try it!!

It's already been accomplished, people have made well over 400rwhp with 2Vs and some don't even have TFS heads.

"dont even have TFS heads".... you said it, not me. Im def not a TFS pp ryduh!

I have "heard" that it has been done but as I said, Im not selling my house to build a motor capable of that when you can put a cam in an LS1 and be there. LOL at our 2v's!

Just think about how much money they would have invested to make over 400hp N/A now take that money and put it towards FI and you have a much higher HP engine

Sash · February 5th, 2011, 08:55 PM

my stroker engine with those heads would run so good.......now with stock heads and stage II cams runs 12.5 @110 and my car is full factory weight,I can emagine with those heads and better cams, will definatly turn high 11s......

not nessesarily & N/A is far better for the real world in alot of cases than FI.

bottom line though, it comes down to the ultimate use of the car more than anything, if you want a dyno queen, FI is a given, other than that, NA has it's place for shure (especially at the track).

DarknessGT · February 5th, 2011, 09:06 PM

hmmm could i have that intake hooked up to a turbo??????

Sash · February 5th, 2011, 09:09 PM

how much are those TF heads?I might start saving for a set....

teej281 · February 5th, 2011, 09:19 PM

What cams is that motor running? I'm sure there are much more aggressive cams out there to make better power. Also, what compression ratio were they running? Also, fuel being used? I have a lot of reservations as to how much more you could get out of a 2v just because people don't usually try some things that could help tremendously. I'm going for 300rwhp with full bolt-on's and cams only and I have every intention of reaching that goal, without race gas or anything.

That intake is overrated, an edelbrock is much cheaper and will make as much or more peak power.

Scott2001GT · February 5th, 2011, 10:00 PM

where's the torque

86er · February 5th, 2011, 11:14 PM

there is also zero accessories being turned also.

If you want big N/A numbers you are gonna have to drop some coin, big bore kit and/or a stroker kit, unshroud the valves, put decent compression behind it and a good set of cams. Its gonna cost a lot, but it can be done

never thought of that..good point!

tbirdscwd · February 6th, 2011, 01:43 AM

the whole 400rwhp out of a 2v isn't a matter of being possible, it is a problem of making that power streetable. You can make 400rwhp out of a 2v without any crazy money like most people will have you believe. hp is calculater based on torque and rpm. The problem is that a 4.6 2v doesn't make a whole lot of torque.....because of it's displacement.........

Unfortunately the max toque out of these motors is in the 325-350 range. Given the tq(rpm)/5252=hp equation.....it is simply a problem of shifting the peak power far enough to the right in order to reach said hp figure. You can do it fairly easily. It just isn't very streetable and can't be done effectively without going deeper into modding the car. The stock PCM won't operate up in the range necessary and neither will the transmission. You need your peak power to be around 6500rpm or above which makes shiftpoints up over 7500rpm which is out of reach of the stock trans and computer system.

BTW, that motor is right at 400rwhp actually. Whoever said 375 gave a number probably even an auto would overshoot. That number is with a 16% driveline loss...manuals are closer to what, 10-12%?

I always though it was more like 15% for the manuals and about 18-20% for the autos

375 400 405 415 that's really not the point. The point is that it's expensive to make NA power with 281 ci or even 300 ci.

The design of the modular engine lends itself to FI, no doubt. Granted the pistons and rods are weak links but 400 rwhp is possible with a bolt on blower.

For example the LSx engines work well NA, just add cams, etc...

I'm a believer in doing what works and FI has been proven in the modular world.

If you want to stay NA that's fine too just be prepared to spend more money per HP than most FI setups.

When TF tested a STOCK pi headed, stock cams, stock pi intake and stock shortblock it made 307hp on the engine dyno with no accessories.
