hey the new low cell cats are not supposed to trip CEL light. the seccond o2 sensor should be further down the line for a better reading. i have fab speed cats on my car and no CEL light yet. i hope that it stays tha way.

if the engine is like a air pump. air in air out. you would think that the better flowing step up with low cell cats would be better for the car's preforamnce

 

I was just looking on EVO's site. Maybe my boost readings aren't that far off. For some reason I assumed the 3.6 was operating at 6 psi. They list the 3.6 as operating at 0.35 bar (5psi).

The 3.4 is listed at operating at .4 bar (6psi).

My installer has seen a top reading of around 4.5 psi, but that was only driving around town. He hasn't done a fourth or fifth gear run, putting the engine under a full load yet.

 

I'm being quoted $9400 for the EVO and $2k for the install (plus tax). Does this sound about right? Anyone have experience with Autodynamica in Houston, Tx? ..they were listed as an authorized installer on EVO's website.

 

that sounds about right. the kit price is a little low and the labor is a little high. together it seems like a good deal. check and see if they have done one before. did they lower the kit price to compensate for the sales tax difference if you ordered the kit directly from EVO? i think the labor time is around 10-12 hours for the kit, plus extras like coolant, new spark plugs, a new MAF (in my case). see what they're including for that price.

check out EVO's site. i don't remember what the 3.4 kit sale price was (i thought you had a 3.4), but they are running some really good prices on these kits for this december sale.

is this the same miykl from the zx10 board?

 

9399 is the sale price for the 3.4 kit

 

i would order the kit directly from evo then and let your local guy install it. sales tax on 9K is a lot of money.

Thanks, I'll ask those questions. I did ask for references from previous costumers. The reply (email) was that the Houston shop is new, but they have done the installs in Mexico and S.America for two years. He refered me to Todd for his references.

Yes, same Miykl of ZX10R.net "fame".

I was looking for a used kit to install under the 'ol shade tree. I'd still rather do it myself just to learn the car's workings better. I would not want to lose any warrantee that a new system would come with by not using an authorized installer though.

 

I never did a dyno run before I supercharged my car. I have a feeling I have a monster 3.4 motor. A few who have driven my car tell me it feels much faster than all the other car who are supercharged.

 

Dog: You might want to find another way of measuring your performance increase than dyno numbers. They really don't mean much anyway. You will find guys claiming some ungodly numbers and yet they can't get their cars to perform on the street. Measure your performance based on the kind of driving you do. Pick a safe stretch of road that you can regularly measure performance times and go there whenever you make a performance mod. For instance, if you like the short sprints in your 996, start measuring the time it takes to get from a dead stop to 100 mph. Your stock engine most probably took about 11.5 seconds to get there. See what it does now. Get it down to the 9's and then you are moving. Or 0 - 150 or whatever you want to measure. Or from some rolling start speed.

This is a the only way to see if the improvements you make are working or not. It is not measured in an artificial enviornment and takes all variables into consideration. You learn to know what perfromance differences there are with temperature changes, etc.

Saying your car has X HP will not, in anyway, tell you how it will perform, but if you measure the actual performance, you will know what your car CAN do and not what it SHOULD do. It will also alert you to any problems you might have with the engine or blower as time goes by. JMO.



You'll notice that most people love to boast about how much HP they have, yet will not tell you their performance figures. Is that because they don't know? Or is it that their perfromance number simply aren't reflective of the power they claim to have?

 

911: I am more of a tangible person, i like to see differences on paper (even if dyno numbers aren't accurate or reliable) than a sense or feeling for improvements in the car. Inaccuracies in human timing and sensation on a road just don't do it for me. I want to rule out any type of placebo or imaginary improvement that in my mind may tell me to the different mods on my car. Yes, although the dyno is a artifical enviornment, the conditions are somewhat controlled, measured and reproducable. (scientists have an artificial laboratory to control the enviornment during an experiment) I'll try to get dyno numbers after the sc and then after the headers and muffler install.

 

There is no possability of timing or speed errors running it on the street. Any good, inexpensive scanning software will record everything for you within 1/100 of a second. But, if paper power is what floats your boat...........


And you are correct about the science lab...and I am sure you are aware of the numerous lab experiments that do not work outside the lab. Your car does not live in a vacuum. But, different beliefs is what makes the world go around.

 

WOOOT WOOOT! you can now count me in. finally have my SC installed (too many track days )

a few things:

4500 to redline at WOT, amazing! kind scary. i don't know how the TT folk can handle their huge HP but i think i will soon get used to it

it's a little louder at idle than i expected. it's alright as it drowns out the lightweight flywheel rattle :O. i love the whine when i finally get on the throttle.

it's not fun in bumper to bumper traffic. i think the parasitic drag paired with my LWF bog the engine down. when i am at a crawl in 1st and i tap the gas a little the whole car bucks and i thought was gonna stall. maybe it's a software glitch. i solved it by just crawling around in second .

 

Try a G timer, ~100$, no better, and no worse than a chassis dyno, just as 'accurate'. It will tell you if mod A has improved performance or not and give you a hp estimate as well.

 

congrats carlos. enjoy. something doesn't sound right with your setup. my car drives like stock at low rpms. maybe it's your LWF.


the gtech is fine and all, but it won't tell you your AF ratio at wide open throttle though

 

A good scanner will tell you everything, including what the AFR is doing at all speeds.
