Rod,

What will the time frame be between your pre and post Crawford Plenum dyno sessions? IMO it takes a little running time for the ECM and front cylinder spark plugs to adjust to the equalized air flow.

Hold your horses with the kinetix plenum not cracking anymore comments. The V4 just started shipping so how can you say that they won't crack anymore. I am getting mine delivered next Tuesday. I'll post my experience with the product after having it at least a month. Then, if nothing happens we can proceed to say that they won't crack anymore but it is too premature to say that right now.

wel im not getting the plenum for a while now i think.. I was considering doing performance mods and then wheels, but i have decided that if i do wheels first, i can sell my stocks for >$1000 with tires and then get exhaust. then im only a small 1000 from being able to buy ts ecu and plenum together. I thinnk that im gonna hold off on plenum until ts comes out with the software for the 2004.5's because i dont want to run any risks running lean until they do.

Dave,
I think that he did his stock dyno last week, though I beleive that he did not get an A/F measurement done.

DaveO, Dyno tomorrow at 9am that will make it 8 days and over 375 miles since plenum install and reset ECU....Rod

I just installed the Kinetix V4 last night. Pretty solid and fits like a glove. I'm not sure how this thing could ever crack, with the exception of heat cycling and getting brittle over time...but the lifetime warranty should remedy that. I like the fact I can keep my stock plenum because I trade cars often.

 

Rod,

It took my TS re-flashed ECU (and front cylinder spark plugs?) a few days and over 100 "open loop" miles to fully adapt to the Crawford V-5's increased, balanced, air flow.

This delay was in line with most all of my car's other modifications. The one notable exception happened recently when I did back to back heat soak tests of the stock air case (with K&N filter) vs the Stillen CAI. The power lost by re-installing the stock air case was immediately noticable and did not come back over two days of hard driving. Re-installing the Stillen CAI brought back the power after a couple of hard test loop drives.

sorry, but what does "open loop" mean exactly?

When you say that it takes time for the car to "get used" to a new mod, do you mean the ECU adjusting for new air flow and A/F, timing etc?
or are you talking about your other things also?

if you have a TS ECU, shouldn't it be already mapped for your mods?

thanks.

 

DaveO, I have my pre and post plenum dyno results on a thread I just posted but you raise a good point. For what ever reason I didn't go pop charger and just went k&n filter. From your results I bet I could add to the gain I got from the Crawford plenum if I went away from the stock air box....Rod
