STILLEN Exhaust & Gen 3 Intake Dynos - 18hp Each!

Crash

Interesting... Nice looking engine bay. Clean. Mine was dirty as hell. (Always working on it, never tidying up. LOL)

Hey I'm sorry guys.. things have been busy and I've been relying on my email notification for this thread, which apparently I read in my email box without clicking back to the site to get more updates.. and hadn't seen these from the last couple of days..

Denny, I can't see the dyno sheets you've posted, both links head straight to photobucket, can you send those to me or repost the links? I don't think it's something on my end... but you never know.

Kyle@STILLEN

Hey Guys,

Josh just told me about the offer Denny has made and we're in. In the past we have always been ready to stand behind our products and put them to the test. We just ask that you follow a few simple guidelines to ensure a fair and equal testing environment.

1) You perform a minimum of 7 runs. We have found that these engines will learn the new parts and we have literally watched the cars gain more and more power on each pull up to about the 9th run. They don't typically climb any higher after the 9th run.

2) You do not remove the car or adjust the tie downs in between dyno pulls. By loosening or over-tightening the straps you can either gain or lose horsepower. The intake must be installed on the dyno with the straps not being touched at all.

3) You document the installation completely with pictures and feedback. Also, tell us what you think of the intake, construction, materials, out of box experiences.

4) This must be tested on a bone-stock car. No other modifications can be on the car for either the baseline or the STILLEN Gen. 3 testing.

If we can agree to these terms then we have a deal. We did the exact same thing for the G37 guys when they tested the intake and it proved to gain the power that we claimed.

These intakes are still in production so it'll be a couple of weeks before we can send them out but we will at least be able to get this ball rolling in the meantime.

Thanks!

Great numbers!!!!

Deal!

Ordered new cats and Y-pipe that should be in tomorrow but I'll hold off on putting them on the car. Is there a certain engine temp you like to see the runs performed at?? The car did lose a tiny bit of hp with the oil temp @220 vs just below 200 or was that an abnormality due to only 150 miles on the car?

Some cars loose quite a bit with heat soak (like my Ltx Vette) and some like the LS1 make more power typically around the third run so let me know.

Absolutely love to see vendors belly up at the bar like real men for a change. As mentioned, it's in everyone's best interest to sort out the posers from the players. You'd really be surprised at what dyno tricks some of the big name local tuners play.

Man.......I just love this stuff.

Josh

e-mail me at the e-mail address in the above and I send you the scaned jpeg sheets. Pretty good with cars.....missed a few geek classes on posting picturers though. What can I say??

Kyle@STILLEN

You bring up a good point about engine temps...I totally forgot that. We will have a set engine temp range that the tests will need to be performed in. We are more concerned with the coolant temp than the oil temp. I will check with my engineers tomorrow morning.

With that being said, you are not wrong about the oil temp rising in these cars and we are working on a solution to this. We work very closely with the Nissan engineer's and they told us a few little secrets about some of results from their testing. We are nearly finished with an oil cooler using a very high quality Setrab cooler. It should be ready in the next month or so.

Here is a similar review on a G37...

Review Stillen 3G Intake Review + Dyno - MyG37

RCZ

Did that guy really just rate an intake install a 9/10? 9/10 should be like a motorswap...

Took 4 guys, 2 hours. Dear lord.

Anyway, 15hp gains...pretty absurd. If it makes 15hp gains for Denny, I will buy with my eyes closed.

Sorry to ask this, but do you have any mounted pics on the 370z? I, along with some others, are curious as to where it sits...

Also, Setrab kit, count me in.

Denny McLain

Engine temp sweet spots are pretty much the norm for almost any car and the traditional way people massage the gain numbers. My problem is no way to monitor the water temp which I also consider is the critical parameter vs oil temp. If ya got something, throw it in the box and I'll nuke it right back.

David Vissard (sp? think I have his last name at least close) believes around 170 degrees to be optimal for making power in a traditional small block Chevy. Bob Norwood on the other hand is an old friend and used to preach to me "heat is horsepower." Bob is a god among the Ferrari crowd ,so tell me what these cars like.

Denny McLain

Quick point I've been thinking about and probably a good time to mention it.

Thermostats? Usually the factory installs these for engine longevity and emissions. Are other ones available where the engine is in the range it likes for more power?

The first thing most Corvette guys do is cold air intake, headers, exhaust, and lower temp thermostat.

JoeyD

^That's a very good point. If the Z is making the most power on the 7th-9th run it certainly likes it a little warmer. However, if we are already having heat issues on the track, won't this only exacerbate them? Or, with an oil cooler, could we keep the motor right in the sweet spot? Does this deserve it's own thread?
