Is this worth the cash? This damn 17.12 is really making me want to hit the 16s sometime this year whihc half explains all thes eposts in the H/A tech forum. Thanks to John denise and wes for the help too BTW.

 

A VTEC controller might help to get you there. It also depends on what mods have you done to you car. HOw about swapping in a nice B16a or B18C..hell even one of those nice LS/VTEC combos sounds good ! !


Good Luck

The only real benifit of this would be its use to flatten out the curves but adjusting your vtec activation point. Dont think you throw it at 2k vtec and its gonna drop a second. I use mine to turn the vtec from the ECUs point of 5700 to 5300. Not sure hoe much benifit you would see on a SOHC. What about a test pipe for you cat? Its somewhat illegal (if you get caught) but for like 15 bucks its well worth it. Also try taking your power streeting belt off and you should hit it as well.

 

Ive yet to see a dyno graph of a test pipe on a mildly modded car that will do anything but cause it to lose power. Why is this? It would seem like common sense that by removing the obstruction a better flow would be created. Well theres this little thing called a venturi effect...

 

good call bill someone here knows what they are talking about

All I know is my Pig Tegra with only boltons go 1.5 MPH at the track with this. Not sure about on the dyno but i was happy with that.


Also PS belt is worth 2-3 hp throughout the band and someone has even told me that if you nuts enough the alternator belt is worth another 3.

You can also gut the car. That usually helps in dropping speed.

 

thats the sad thing I DID gut the car....Yeha Ill try the belt next test and tune session.

 

Test pipe with a stock motor = NO TORQUE. Hondas need a little restriction and back pressure. Its one of the very few things that GIVE our lil 4cyls torque.

As far as a VTEC controler - I wouldnt waste your money on one with an internaly stock car. Honda knew what they were doing with their production motors. The only time you really need to adjust your VTEC switchover point or change fuel curves is when you have some internal work. EXAMPLE - Going to camshafts with higher lift and longer duration will usually warrent you moving UP your VTEC point as to not drown out your motor with fuel in the low end and things like that. Id start saving for that swap. Save every penny that you would normaly throw at your car and one day youll be 200xs happier.

Mmmm I love backpressure arguments.
So how do you figure that backpressure will help your car? Well in some cases it does due to valve overlap since exhaust scavenging can actually over-scavenge and suck out some of the intake charge. Anyways in that case backpressure will prevent such an excess of scavenging BUT if you actually tune your car (cam-gears) you can play with the overlap and therefore negate the need for any backpressure and increase fuel economy as well since there will be no loss of intake charge and a greater loss of exhaust residue. Cars only need backpressure if they arent tuned well or factory requires a silent exhaust note. And as for the argument that larger exhaust piping decreases backpressure and thats the reason why you lose power nope its primarily due to the loss of exhaust gas velocity in relation to piping diameter. Well thats enough silly talk time to go grab a beer...

 

Ah ha but Bill arent we talking about an internaly stock motor here? Does the motor at hand (the one belonging to the person that started this post) even have an adjustable cam gear which can be tuned beyond facory specs? Are we going to argue this? I believe it was brought up that he should add a test pipe to his car which is internaly STOCK. In this case it does play a role.
