Although I dont know how to reset the ECU right now, I know anytime you much with the intake, it was good to reset LS1's ECU - this Im sure is no different.

Tune will almost always be beneficial. Necessary, no.

however, after rethinking about the location of the filter in relation to the front fascia/bumper and chassis/foam, imo it will actually suck air from underneath the car or the air coming off the asphalt that is bouncing off the radiator... i cant find anywhere other paths the cold air can come in at...as such, i am thinking that if it is hot outside/at the track, this CAI will actually not be sucking cold air in... which kind of goes against what josh is saying and gives more reason to get the scoops...

my problem with this is that i dont like the scoops... so i think if stillen is in development of a front fascia body kit for the z... i think they should put in consideration to establishing better in flow coming from the top of the car/bumper... with that, i believe the 15-20hp gains will be easier to foresee... ( OORRRR ... just take out the foam that is blocking the air... but am no mechanic/engineer, which means i am not quite sure what the impact would be to the car)...

... all this thoughts will probably be answered after SEMTEX's dyno results... -Semtex, just in case my thoughts hold water... i think you should bring your shotgun and use it to put holes on your bumper and re-dyno the car...

There are only so many places you can put these. After looking at the other possible options, it is clear that STILLEN put these in the best possible place.
Remember we also have to install an oil cooler in there and there isnt much room anywhere else. We were pretty impressed with fitment actually, the intakes fit perfectly in that spot and dont need any type of supports. If I had to design the intakes again, I wouldn't change a thing. I may add some gold or plain reflexive foil or a thermo-tec sleeve to the pipes because I dont care as much for how they look, but rather how they perform. This is what Im talking about...

Leave the structural components alone while you can.

1) No, just drive a bit and it will adjust real-time

2) Necessary, no. Beneficial, always.

Thanks RCZ!

Video/write-up/dyno = rep points!

semtex · 03-27-2009, 10:59 PM

Good job, RCZ! I'll be getting another dyno on mine next week, so we can compare results then. (Plus we'll be able to see what these intakes combined with the exhaust and HFCs yield number-wise.)

Brazilbro · 03-27-2009, 11:11 PM

I'm glad we are seeing some different dyno results. The results posted by stillen was a little dissapointing to me because of the 18hp gain was really only after 6500k rpm -7500anything below that was about on par with stock numbers.. from your graph we see big gains from 0 all the way up to redline.

LOL! It's not our first rodeo..

We did over 50.. yes.. five zero.. iterations of this intake design before we were happy with it.. all of it on the dyno..

Every little detail of the intake can make or break the horsepower gains..

Thanks for the review Raul, it seems like everything went smooth, I'm glad.

I think your gas mileage this tank might not be so good.. after 5,500rpm this thing screams.. but you've got to dump the right pedal to get there..

RCZ · 03-27-2009, 11:42 PM

^ I was thinking about this while driving back home. Its so tempting to ride out the gears now

I think maybe you put that in just for me !

Super write up ! Great pics ! THANKS for taking the time to capture all the data and post !... I think we all have our validation that these are the ones to get... I'll be pretty dang surprised if we see anything better

RCZ · 03-28-2009, 12:00 AM

hehe, it wasn't, but it fits rather well

Endgame · 03-28-2009, 08:17 AM

RCZ... Well done Sir!! This is excellent and most encouraging news. Not to mention this thing sound HAWT!!!

I know it has been covered before, but I must ask... Are we SURE this will not cause further cooling issues with the partial blockage of the radiator with the bumper on??

Josh feel free to chime in on that also...

MightyBobo · 03-28-2009, 08:28 AM

Well done RCZ - thats funny, I seem to remember a discussion where I was saying something to the tune of 310 WHP with a top quality I/H/E setup and you agreed with it....hmmmmmm, eh?

semtex · 03-28-2009, 10:17 AM

FWIW, I'll be doing my dyno with the bumper cover on, not off. I'm going to see if they can fit me in on Monday. Of course, I have a different exhaust setup than RCZ, so it's not going to directly answer the question of whether or not he'd have seen the same gain had he put the bumper cover back on prior to the post-install dyno. But it'll at least give us some contrasting/corroborating numbers.

RCZ is running just stock exhaust, is he not?

I believe so, yes. I think he plans to go with the Stillen/Berk setup like mine for the exhaust. Not sure when, though. Hopefully, at some point in the not too distant future our cars will have the exact same setup (which is where we're headed), then it'd be REALLY interesting to compare our dyno numbers and see if there are any major variances.

Agreed. The Stillen exhaust is what I have my eyes on myself, so i'll be VERY interested in seeing your results. Will you be using a Mustang dyno, also?
