racing from a dig in 1st gear (2000-5000rpm) my motor just dosent feel like its got the power it should have, once the vtec kicks in ive got plenty of power from then on, but its just that take off im missing, any ideas on how to get some low rpm hp? its a h22 with aem cold air and a full megan exaust, and maby a type s head after thursday..

there are no problems with the motor, and i just did a tune up and changed the belts and water pump, im just trying to figure out how to get more power

im planning on getting a skunk2 pro series intake manifold soon but i was told thats helping the high rpm more than anything

any input is greatly appreciated

doing little bolt ons and not synching the fuel and ignition will not result in much additional power. You have a 4 cylinder, not a v8. Its not going to have much "low end" unless you build the block with higher compression, bigger stroke, bigger bore.

 

Any reduction you can do to rotating mass will have the same effect as adding more power. Remove balance shafts, lighter flywheel, loose PS and AC, D-series alternator or lighter pulley, lighter crank pulley (no it won't blow up your engine), etc...

 

yeah the pulley(s) are something ive been thinking about changing, the ps will prolly be gone, but hawk as you may know, texas tends to get quite warm around this time of year, THE A/C WILL NOT GO! lol

 

Hahaha, yep it's about to get hot around here that's for sure. I just roll my windows down and sweat it Plus our other cars have AC if I get the urge.

 

yeah and that 5th gen sunroof comes in handy too especially on the highway lol

i work for an ac and heating company and believe me, when i get back to the shop to go home nothings better than nice cold ac lol

I dont know about that.... My crank pulley bolt was toruqe on their good and tight, to OEM spec, and it still managed to come undone, after 6 months with the UR Crank Pulley resulting in Epic Failure.

I seem to think that it was the lack of Harmonic Damper on that thing that caused that to happen.

I have had mine for 5 years now with no problems and lots of spirited driving. It was probably user error.

Lets not start that whole argument again

 

I dont know about that

User error, I dont think so as well. There is no reason, why a crank pulley bolt, torqued on there right, should wiggle off after 6 months of driving.

Unless someone came in the middle of the night and loosened it on me, which I highly doubt, but its possible.

There is no good reason, that the bolt should of come off. Now it was a junk motor, mabey thats it.

I dont know about that either, but the fact remains, that after 6 months of driving with UR Crank Pulley, the bolt came undone.....

And because of that, I will never use a crank pulley, with out the rubber damper thing.

And I dont care to argue the fact, cause it could be any number of things, except that its user error. No way in hell, that is my fault

Why so many, commas randomly scattered, throughout, the sentences?

I think a lot of us just became concerned when you were trying to pry your flywheel off with a crowbar (with bolts still in) and blamed someone else from another country for telling you to do it.

Each time the engine runs, it will tighten the crank pulley bolt a tiny bit more, so if you get it tight enough to start with it should never come loose unless you have other problems causing vibrations in your engine. I hand tightened mine many years ago and it has been fine ever since...no tq wrench or anything (not to say that that's a smart idea)

 

Lol, yeah I remember that.

Anywho, I still wont use that brand crank pulley again.

Yeah the commas, I talk, Like, I just, Ran a, Marathon...

So anyway how can one go about looking for harmonic distortion in a motor?

Hahaha, I was hoping I didn't offend you with that post

What brand pulley was it?

You may, have, athsma, ,,,,jk

The best thing you can do (that I know of) is to have everything balanced. A non balanced crank, flywheel, pulley, etc..or pistons & rods that don't match weights or bad timing or motor building could all cause harmonic problems. That's why Fords have giant rubber rings and are literally called harmonic balancers while ours just have a little ring to dampen the force of the AC coming on

 

Not offended.

How do you have everything balanced out, from a DIY point of view

 

Well, a stock engine will be balanced, and anything you add to it can be balanced at a machine shop. No real way to DIY...

I have installed a Fidanza flywheel and a UR crank pulley without balancing anything, but they are name brand parts that I trust, and no problems have occured.

You take in your crank, flywheel, pistons, etc. to a machineshop that does engine balancing.
