Exactly what I was thinking.

Valid question and we all know how engine oil cooling is key on those cars and it is all counted for .

sounds great, sam.... look forward to watching the details unfold

do you really think it is that ugly ? I think both kits have their merits... the stillen intake is at least as attractive as the plastic engine cover that nissan slaps on OEM... and stillen can easily design something to complement the intake and cover the other parts of the engine for those that care... and the GTM kit is stealth, which some folks will like

so back to the very serious issue of oil cooling... where is it, please ? i've instructed liquidz's avatar to keep doing push ups until we get a satisfactory answer! lol

In my own opinion the problem with Stillen intake is lot bigger then the look of it, It will hinder the performance of the car period .

In regards to looks: I dont drive around with my hood up, whatever has the most gains and best quality please.

Honestly yes i think the stillen piping looks like something i would see on homemade turbo .com. While i've not seen it in person, the Y portion looks like it will flow horribly. (could just be the glimpse we get in the video, i'm waiting to see it in person). If you want to continue to compare the two kits my next worry about the stillen kit would be the SC sitting so far away from engine, which seems similar to the previous vortech kits. That usually causes a lot of deflection in the bracket contributing to the belt slippage that everyone complains about. Hopefully they learned a lesson and added a way to stiffen that thing up a bit. Final concern with the stillen kit would be MAF location. i'm waiting to see where they actually put them, but i'm guessing they are going to have to share that main charge pipe. Not sure how the factory ECU is going to like that, or the fact that they are not reading a real intake air temp. Unless they add another IAT sensor post intercooler how will the tune know to change if the temp changes? I mean you can make the most efficient IC set up in the world, but it will change temps to some degree through the course of driving/racing etc, and the ECU should be able to see this to properly compensate. I guess i just expected something truly amazing from stillen especially after all of the talk about custom intake etc. Turned out looking a lot like an older vortech kit, which i really am not a fan of.

As far as the oil cooler, i'm sure GTM has something figured out.

travisjb · 01-31-2010, 02:19 PM

you seem pretty knowledgeable about all this... mind if i ask what your involvement is in the industry? are you just an owner/driver, or do you have some skin in the game? i'm curious... also, have you posted those concerns over on the stillen thread? i'd like to see how they respond

now this is getting interesting! guessing you wouldn't say it unless you could back it up... looking forward to seeing some numbers

Indeed.

Can you give me the basics of how the bigger intake will hurt?

WICKED_GRIN · 01-31-2010, 02:32 PM

^^ me too!

Obsolutely, I have no idea what they were thinking. I will leave it at that for now .

There will be a time and a place for all the factual technical discussions, you can count on it .

StillenZ · 01-31-2010, 02:52 PM

lol... I saw Sam's response and went straight to the bottom to ask the same question... guess I'll just be patient lol, this sucks

Zguy · 01-31-2010, 02:57 PM

Sam is clearly an expert on these platforms, I am very excited to see what he has to say about the stillen system. For me I dont like the water/air cooling system on the stillen.... Im a fan of the Air/Air systems... Then combined with the intake actually housing the cooling fins with water running through it... I just dont like it...... It sounds like trouble waiting to happen.

m4a1mustang · 01-31-2010, 03:20 PM

It seems to me like GTM has the ideal SC setup of the two. However, they are a fair amount further along in the process than Stillen is at this point so I will keep my mouth shut (mostly) until we see numbers from both.
