So has the grimmspeed intake proven itself????
 

So ya i am looking at intakes and am seriously considering the GS. I dont get on the forums much so i havent been following the feedback on the GS. For those of u that own the GS intake or have direct knowledge of its actual performance can u chime in. I am currently running the OFT stage 2 with an EL header. I want to round it off with an intake that actually works and doesnt trick the maf.

I know a lot of people have had better success with just a drop in rather than an actual intake.

If I could go back I would not have bothered with the grim intake. I didn't really see any gains from it compared the drop in. I am running e85 so results might be a little different on 93. Otherwise it's a great product and looks great under the hood.

What drop in a r u running? I was looking at the hks hybrid. Any info on that one?

I had the GS intake and it was a pretty nice intake. there was a stage 1 OTS tune from OFT that was specifically tweaked for the GS intake. I am not sure if there is a stage 2 tune for the GS intake though. however, I sold my intake to buy my oil cooler lol. now I just use a Perrin drop in filter. obviously, the intake did not do anything crazy to power levels but being able to hear the suction from the engine was pretty cool. the power difference from the GS intake and a drop in filter is minimal and I doubt you will be able to notice it.

basically all the drop ins are the same based on the tests it seems.

Intake dynos done at FFTec for Vishnu/OFT. Seems the GS does something, just a question of is it worth it to you. I like a clean engine bay and plan on a tune so why not. But I also got it during the GB so it was cheaper.

There are plenty more drop in dynos and GS intake dynos if you google

consider the new injen evolution intake that was just released on ft86speedfactory! Someone needs to test that sucker out to see if it really does make the 15hp and 11lbs of torque that it claims.....I'm veeery curious but don't wanna shell out the dough for it.

There was a filtration test done ages ago where the HKS performed the worst/4th place. Blitz was 3rd, K&N 2nd, and A'PEXi 1st. Assuming nothing's changed, A'PEXi should be your safest bet. Cosworth should also be a safe choice and I ran that for a year.

I'm just using OEM replacements now. The power gains from a high-flow filter aren't that noticeable in the real world, but you do get some extra whoosh sound.

To get maximum gains, you would need a custom tune. Running an off the shelf tune and an aftermarket intake will most likely net you negligible gains.

It cleans up the engine bay SO much. :)

It also performs without issues without a tune - something not all intakes will do! Whether you can squeeze more with a tune, well - it wouldn't surprise me at all. I'll keep it just to avoid all the plastic junk in the engine bay.

I just got my K&N today but I still plan on getting either Takeda or GrimmSpeed CAI after I get header and tune in about a year.

So has the grimmspeed intake proven itself????
 

Try the new injen evo2k it's the only intake that's on US market that's like a ram air intake like some JDM expensive stuff which you can't get on this side of pond...>.>

Please be the white mice for the community. :D


If you just want sound, blitz advance power is the absolute best...

This thread is pretty ugly, BUT I'm always down for some intake talk:

Lately when I cruise through these forums I read in pretty much every intake thread that you should just buy a drop in filter and call it a day, and that intakes are worthless. It's very short-sighted unfortunately.

During development we posted literally everything, including a study on the stock intake system, and pressure differentials across all parts of it. Lots of really really cool info, which showed us where we could make improvements. We also posted a 48 page thread, where we showed off tons and tons of dyno charts from our "141 pull, 61 miles at WOT, 23 intake configurations in a single day," dyno day (http://www.ft86club.com/forums/showthread.php?t=50492). It's a pretty long read, but there is all kinds of relevant info in there including stock runs, drop in filter, silicone elbow, modified snorkel, a few different brand intakes, prototypes, etc.

Now at some point people started to say, hey the horsepower per dollar of an intake isn't that great compared to a drop in filter. And that's true if you look only at the peak HP numbers. Even if you're looking at total power under the curve, it's not worth it to some people, and that's just fine. But lately the automatic response to any intake question on this forum is: Don't buy an intake, just get a drop in filter, it's way cheaper and almost as good!

This is why it's not almost as good:

http://www.grimmspeed.com/content/im...GSStckSnrk.jpg

What you're looking at here as far as runs go (in order) is: 1. Stock 2. Drop In Filter 3. Drop in Filter and Silicone Elbow 4. GrimmSpeed Prototype intake.

Before anyone comments on how low the horsepower numbers are, remember that this is a Dyno Dynamics dyno, which reads around 75%-80% of what a Dynojet reads. This applies to the deltas as well.

So this is still when we were using our prototype intake and airbox, which was not as refined as the production version. You'll see it's making the same peak horsepower as the drop in filter and silicone elbow, but it makes more power literally everywhere, and sooner too. Granted its only a few horsepower here and a few ftlbs of torque there...

But it's not a fair comparison: Look how LEAN the drop in filter runs are. 14:1? That's wildly unacceptable at WOT. While our intake (untuned) is making more power, and at a safe, stock air to fuel ratio. Over time once the ECU starts pulling timing due to knock, that drop in filter isn't going to be making the same power.

So you'd want to get it tuned. And all of the sudden that drop in filter is a lot more expensive... Those drop in filter dyno comparisons are pretty cool and very consistent, but they also do not show the AFRs.

Also, just to reiterate once we took the production version (not the prototype) to a dynojet it made 10whp, which is double what a drop in filter makes. This is also where we learned that we were not putting the air filter on the correct distance on the intake tube, and were hampering our own power production. Once we figured that out, we immediately made the power we did:

So at the end of the day, yes our intake has proven itself. And it is a great candidate for a lot of people. Do you want something that looks better under the hood, requires absolutely no tune (even has a MAF-scaled OFT tune available if you want to make even more power), and sounds better? Then our intake is a great choice. However, if you want to just make some power, don't care about running leaner at WOT, like the look of the stock intake, and don't want to spend as much money, then a drop in filter is what you're probably looking for.

Basically, if you're looking to keep your car long term, and keep it NA, grimmspeed intake is a good option.

Personally I want a SC in a year or two, so for now all I have is a drop-in because anything more expensive wouldnt be worth it for me.

Thanks Chase @GrimmSpeed for the informative post and to everyone else with constructive answers :thumbsup:

Bravo bravo! Awesome reply chase! That was exactly the input i was looking for in a boiled down version!!! And because u gave an explanation with dyno chart on the actual benefits versus the drop-in i have decided to purchase the GS. Thanks so much.

That's rearly weird that just a drop in filter could cause the engine to run lean especially 14:1 lean. and don't understand why that would happen as your not altering the position or the size of the maf sensor housing, unless it created large amounts of turbulence or something, then with drop in and elbow or dropin elbow and modded snorkel is much better. Or it was an oiled filter and its contaminated maf ?


just not experienced or seen that issue with just a drop in filter

There's no way a dry drop in filter will make you run lean, unless you do something ridiculously stupid like reset the ECU before putting it on the dyno like some vendors like to do.

And we saw it repeatedly. When we did testing that day we did 3 pulls in 3rd gear, and 3 more in 4th gear. Every single one was consistently lean like that. All 6 pulls.

http://www.grimmspeed.com/content/im...norkel_4th.jpg

DIF and modded snorkel didn't make it much better, about a quarter point.

http://www.grimmspeed.com/content/im...eelbow_4th.jpg

And Silicone elbow, DIF, and modded snorkel wasn't much better than that either, still very lean.

And yes, the K&N is an oiled filter. But no, this is not an example MAF contamination. These were some of the first pulls of the day, and if we had a contaminated MAF we would have seen the same poor results on all of the other intake combinations were did.

I do agree that it is really weird for the reasons that you mentioned, but it also certainly is not the first time we or other people have seen this effect with drop in filters.

Also that post is right here: http://www.ft86club.com/forums/showp...&postcount=200

It's a good one because it shows stuff that people usually never see like power gain from the silicone elbow, modified snorkel, and combinations of everything.

Do you have any data on that, or is that just speculation? If you're insisting that based on the idea that the oil from the filter is contaminating the MAF, then that idea is already unfounded from what I posted above.

And I do agree with you, there are lots of vendors that do "stupid things" like reset the ecu before a dyno run. Usually before the dyno run that they want to look "bad." We reset the ECU before every single intake combination (so 23 times), but we were also using an OFT with stock tune, but that forced the IAM to 1.0 upon reset. This was done for consistency between all combinations, and to clear any sort of learned values.

So while I've seen a ton of dyno charts from people from all sorts of intakes and drop in filters, but they almost never have AFRs. We did extensive testing, and provided tons of data including all kinds of dynos with AFRs for competitor's products. And even better, we don't have a dyno, so 100% of it is 3rd party testing. The only thing we did was change the intakes on the car. There is no reason to think that this data isn't accurate, especially with the extremely large data sample that we have, and how consistent the results are.

I purchased the GS and am awaiting its arrival. Once installed and thrashed on for a while i will post a reply with my feelings on it.
