Would lowering the vtec point from 6000 to 5000 rpms help the s2k to be any faster?

 

it wouldnt change top speed at all, but i would think you would accelerate, because you are in VTEC for about 1/2 the power band, i would also think it would cause more wear and tear than nessecary(sp) because the motor is being over worked than it is used to, or designed to...
if you ask me, i would never change VTEC point, unless it was a motor swap because Honda changed the stock vtec point, IMO its not a good idea, to me, there are more risks than benefits

 

Why only drop it to 5K - why not just off idle?

Think logically - if Honda could do it, keep it within reliability targets, meet all Federal guidelines, and so on, wouldn't they have thought this themselves? But just doing it is likely not a good idea. Remember, it is a tuned system. Intake tuning,spark and fuel mapping, and most of all, the camshaft profiles must be considered. IMO, Honda did all the math and vame up with what we have today. It's not like the good old days, when a stock car almost invariably would benefit from a few more degrees of spark advance. I know that the aftermarket ECM's drop the VTEC start point by a few hundred RPM, but I think they advise other mods as well. It might gain a fraction of a second per lap, which is important in racing, not as important in a street car.

 

It's not as bad as you think it is. I got my V-tec set to kick @5000 and I love it. There are pro n cons. The chose is up to you. Have fun if you ever decided to do so. You should get a v-afc and then dyno your car..

 

So tell us what the pros and cons are

 

It will be faster if you have the right parts and tuning to go with it, if not, I would say it will be slower. Honda set it at 6000rpm for a reason!!

 

i'm with everyone else on this one.. honda aint no damn fools.. they set it at 6k for a reason. i wouldnt tamper with it !

I heard that when u rais the v-tec point you get more hp out of v-tec. I had a GSR and raised my v-tec from 5400 to 6100. When v-tec hit it hit very hard unlike the stock 5400. I set mine so it would hit right when i shifted from redline. My RPMs would drop to 6150 every time i shifted so why waist the v-tec that i am not using. It is easier to explain in person...being Italian i could use my hands to talk a little. LOL It is like cramming all that v-tec into a smaller box. I never got my car on a dyno b/c someone stole from a car show. But it felt better with the v-tec where i had it. Just my 2 cents

 

The biggest advantage of lower vtec is when you do a highway pass. It enables you to get going with ease when he vtec kicks in at 5000 its all smiles

The Comptech s/c car in the car and driver issue of tuner cars had a lower vtec. Its tricky to get the fuel just right with the vtec engagement lowered. But once ya do the vtec transition is very smooth. once in a while i switch back to the stock engagement and it is no fun seems like I am always waiting for vtec. I get caught in that dead mans zone between 5000 and 6000 to often. Having the vtec set at 5000 with the proper tuning is the best. Much smoother, better drivability.

If you just lower the vtec to 5000 with no fuel adjustment you will get a serious bog. But with the proper tuning it is a joy!

Be prepared though your gas milage will go down. You have to add fuel between the 5000 and 6000 rpm range or ya get a bog-hesitation and the a/f spikes lean! At this point I have not been able to go any low than 5000. If I go any Lower I have trouble with the a/f ratio and it has a hesitation.
