***K24Z1 project teaser***

What did you use to pull the AF ratios? the OBD2 port?

Innovative motorsports LC-1 wideband a/f gauge/data logger...

its a completely separate wideband o2 sensor which i calibrated before the run

now for the good news hehe did a trial run with the J32A3 throttle body and 3" intake this morning, i didnot port out the manifold so it was only running thru 62mm stock opening. I will be using this dyno as my baseline for the build.

So here is the printout (temp was 16degrees):


and here is my A/F log for a run:

Do you stick it up the exhaust or did you plumb it through a port in the toda test pipe?

its welded in the TODA test pipe just before my cat converter... pretty much directly opposite the stock o2 sensor

and yes i know its a little rich lol but thats good because once i get all that extra air smashing thru there, the ratio should lean out to more around the 13 mark

Hang on..is that dyno from your normal motor plus the new intake and bigger Throttle Body?? or have you installed the new K20z head and thats the results?

Im not sure what im seeing?

That a different dyno from the original dyno that you and i used that was showing 133kw? Bit hard to draw comparisons in that case.

Either way its looking mighty impressive.

Good idea to list all the mods for this run, seeing that this will be your baseline.

lol its my normal motor with the J32A3 TB and custom intake (plus the comptech exhaust)... i wanted my baseline on a dyno dynamics dyno, as the mainline one seems to read lower than every other dyno ive seen...

lol this is the dyno you got 86kws on lol

that dyno sheet is a little weird (dont know what happened there lol) i have another overlay printout, showing like 3 or 4 different runs i did this morning... ill try scan it in later tonight aswell...

Good idea to list all the mods for this run, seeing that this will be your baseline.

-J32A3 throttle body
-RBC intake manifold (stock 62mm inlet)
-P2R thermal gasket
-Comptech exhaust
-TODA racing headers
-hiflow metal cat
-custom 3" CAI



and yes, i did not have my P2R spacer in (it still needs to be modded to fit the J32A3 TB)

ok heres the overlay:

BLUE line = WOT to redline, then back off, then repeated
GREEN line = Normal power run (i think i got 142kws on that one)
PINK line = Max power run (using as my baseline)



A/F statistics for 3 runs on the dyno... this takes into account idle/WOT/injector cutoff (hence max 22a/f)

Its all good. Nice figures for those mods, but with respect i dont trust that dyno. thats why I went to the one you suggested. As you said i got 86kw on that one and 118 later on at the other one.

Why did you swap dynos mid mods?

this is actually the dyno i used for my very first run... so the mainline one was actually the one i swapped to "mid mods"... and as i said before, that mainline one reads low... i know plenty of guys who get lower than usual figures on mainline...

i trust that dyno... its been very consistant for me (and others)... lol its just a shame ur VSA was on when u did ur run... you mightve got higher than 118kw...

the majority of people seem to use dyno dynamics, so by me using that for all my mods, its a little better for comparison...
(and yes i know you cant compare different dynos done on different days - but using the same brand and program is better than nothing)

[Suntzu]

Ok. That fair enough.

Im just trying to gauge the improvement of the TB. And your last dyno was 133kw and the same the mainline where i got 118kw. ( i got 86kw at the dyno dynamics place you got 146kw)

So theres no baseline for the TB. But thats fair enough its not worth doing a dyno for every little mod.

Now you have a firm baseline on the Dyno Dynamics and now you can get stuck into the serious head work.

it will be exciting to see what you get next!

Let me know if you are going to pulfords again ( im only 3kms from their shop). Id love to see the next dyno run.

cheers

[aaronng]

Both of you need to stick to the same dyno so that you two have semi-comparable numbers. LOL

[Euro08Jaz]

so which dyno are you guys sticking with?
