Klze lack of powe(hp)

wertys · Post by **wertys** » May 2nd, 2012, 10:01 am

Car runs very nicely, compression test from 1 to 6 is 200 205 195 195 205 205.
Idles at 900,
Klze curved neck everything stock but 2.5in exhaust line incl ebay headers, vibrant reso, vibrant cat and vibrant muffler. and kl36 ecu
I have no pflow im using my k8 air bowl(dunno english word lol)
Finally, the problem is that i do 16.3 on the 1\4 mile which i was told was very very bad for a ze i have a 1.01 reaction and 2.353 on 60ft
The only things not connected are the 3 egr connectors and a vacuum that goes into the charcoal canister(never found the hole) anyone has any ideas?

16.3

what size wheels are you running? also it sounds to me like perhaps your VRIS may not be opening up. Do you have a check engine light on at all?

205 55 15, no check engine and ill check vris in an hour...can this be checked just by winding?

start the engine and just move the throttle by hand up to about 3500rpm. You will see the VRIS actuators open and close.

By "air bowl" do you mean the air flow sensor? I think you do and that should be fine with the KL36 ECU as the JDM cars use the same sensor as us. Maybe your air flow sensor is not functioning properly. You can test it by following the instructions in the manual. http://www.mx-3.com/manuals/showimg.php ... F2-150.gif

Maybe the brakes are dragging? I don't know. If it feels string and runs nicely all the way to redline it should be faster than that.

My first time dragging I was 16.05, maybe it's the driver, took many many sessions to get down to 14's and tweaking the car, knowing how to launch, etc. Reaction time doesn't affect your actual 1/4 mile time.

Some guys also had issues with their throttle cables not pulling the butterfly all the way open on the TB

Hows your gas mileage? Should give you a sign on how well the motor is running...

I had that issue on mine, my car has a custom throttle bracket and was very loose not opening all the way.

Did you have someone else in the car with you? that could be a factor

Bigassed stereo system?

I remember taking my ATX RS out to the drags for the first time with stock steelies and my drilled out air box, 19.1 in the 1/4. That was with the hold button locked and launching from neutral to Drive at like 3500 rpm... The second time with the Turbo B6DE and MTX at a 14.1 on 6psi. My new house is only a couple of miles from the track

Not only that what rpm are you launching at and what rpm are you shifting at?

wertys · Post by **wertys** » May 2nd, 2012, 5:03 pm

900 idle to 6.5k...im scared to go higher

and humm i just found that both my VRIS were closed ALL TIMES... started looking around and found a hose that seemed plugged in but actually wasnt... could this be it?! so much loss of power being due to VRIS?!

Each VRIS solenoid has an electrical harness connector. Make sure they are both connected.

Here are all the parts of the VRIS system...

I don't think this would account for a large loss of power. I don't know your skill level, but I'm leaning toward agreeing with Nd4SpdSe. Perhaps you need practice?

Josh · Post by **Josh** » May 2nd, 2012, 6:04 pm

That very well could be it, no VRIS and a 900 rpm launch. Slow launches can be a killer. The VRIS is supposed to open up as you are making peek hp so if they are not opening you are not seeing your full potential, it is probably a difference of like 20 hp or so. Which may not seem like much but in a small car like the MX it is kind of huge. Unplug them and drive a round for a little bit, and then strap them open and drive around and see how much you notice.

kinda seen my wheels spin after i plugged them lol so tomorrow night imma test my skills again

how healthy is the engine ?? spark plugs / wires / air filter clean /

how about the fuel filter ? has it been replaced ?

other ideas are your flow sensor is messing up your ecu

wertys · Post by **wertys** » May 2nd, 2012, 6:59 pm

compression is good, brand new sparks , wires are just fine(NGK), air filter has 15k on it and i havent touched my gaz filter
