Iv'e made a comeback, the IM made VTEC so fast it sent me back in the time consortiom, haha i joke i joke i keed i keed. But the power was there, a very good improvement. Unfortunately my shitty track in this crap hole isn't open in the winter so i can't go and time it.plus I'm going to wait a few weeks and get his header so i can get the Hodata installed and tuned.I want to do everything at once, unfortunately. I may go to vegas and possibly have Dave tune it, we'll see.also at idle The stoichiometric reading should be 14.7 and at WOT ideal as hell would be 12.9-13.0.and how does a wideband o2 sensor install and a good brand? just looking for some insight and i like several opinions...

[wed3k]

how does the Hodata compare to Hondata?

LOL!^^

Anyways, WOT afr's should be between 13.4-13.8, every engine likes something different.

I recommend any zeitronix product, innovate product, or plx devices. Try and stay away from AEM as they read off a bit.

[oneoffaccord]

its like a 96-00 civc dx/lx intake

Perhaps you felt like vtec went by so fast because you lost lots of torque with that setup.

thats what i was thinking but i didnt want to make speculative guesses as i dont have enough tuning experience to discuss custom manifold designs... but... with no plenum, would you not lose lots of low end torque in exchange for the hp?

[wed3k]

is he running cams with that? id run some high end cams with that setup.

Yup, you don't have nearly enough velocity down low because of short runners but up top you get tons of velocity with enough air flow.

I'd like to have a day with the car and put a wideband o2 sensor on each runner to see how they differ in readings.

My aem always ran within .03 a/f ratio of the dyno's wideband so thats pretty acurate.

[d112crzy]

I've personally seen them read off by .2, compared to a dyno. A very reliable source has had them read off by .75!

When you pay a high price for something, you'd expect it to act as advertised.

They say its accurate to .01.

Big plenums are usually good for top end.

Nice IM. Looks like a lil side draft carb lol.

I dont use the aem anymore on to bigger and better things! The prologger!!

it seems to me that the small filter design may also be hurting the breathing capability.

by doing what you have done as explained earlier, you have lost low end torque. another way you are loosing the low end power is by placing the filter directly upon the throttle body. Notice that you rarely see this done, because it distrups airflow.

with an intake on their, it allows air to already be inside the filter creating a funneling effect, whitch in term creates better airflow throughout the rpm range.
