so you have them installed but didnt get a dyno yet? did you feel a difference power and performance wise? does the butt dyno tell you anything?

MaxSE-R

i would be in pending more details on these.

anyone know the melting temp for the plastic?? to an earlier post, i dont think they would make a plastic gasket that would melt that easier from the heat of the head. so you shouldn't be smelling any burning or melting plastics from these.

Ok, these are NOT Maxima dyno charts, but they are points to consider for these intake manifold gaskets. I know everyone is screaming for dyno data on a Maxima, and we are working on that. Hopefully in the next 3 weeks, we can have the data you are looking for.

In the mean time, here is some dyno charts from NextGear's website for a 2002 Civic Si with a short ram intake, and a 2000 VW Passat with an APR Stage 1 ECU upgrade.

I spoke with Don @ NextGear this morning and we are looking for a 2k2-2k3 Maxima in the Nashville, TN to Huntsville, AL (I-65 Corridor) for dyno testing on the NextGear Intake Manifold Gaskets in the next 3 weeks (before Maxus 2006).

I will be posting this in the SouthEast section also.

I have emailed them twice asking questions about their product but haven't gotten a reply. I'm assuming the emails never made it or else were somehow overlooked.

I'm about 6 hours away from Nashville, 7.5 away from Huntsville. Where exactly is their shop located? Since this is going to be a promotional test, everything is done for free? And why can't you be the test mule? It would seem that you have been in closer contact than any of us with him. I feel I am too far away to justify $3 a gallon gas and a hotel room to boot for a part that's only going to cost $100 if purchased! lol

I'm honestly interested in the results of the dyno and looking forward to seeing it on paper, provided all variables remain the same, just like everybody else.

Count me in for sure if the dyno results are positive. Thanks for finding these. lets hope the dyno results are good.

Well, to answer the first question, they do not have a shop. These tests would be done at a dyno shop (DynoJet). There is one in Nashville (that in the past has been less than accommodating(as far as getting a dyno scheduled, allowing parts swapping, and not to mention expensive as crap) and one in Huntsville (that is VERY accommodating).

Second question, will "everything is done for free"? I do not work for NextGear so I do not know. That would be a conversation that needs to happen with Don Napier after he decides on a test subject and location. I would expect them to pick up the tab.

Third question, why can't I be the test subject. I have some whacked out a/f ratios right now (i.e. a problem I am tracking down) and I wouldn't want to unfairly skew the numbers on the good or bad side. I dynoed stock about 10 hp lower than 'the norm' with a very very rich a/f. Once adding the Cattman Gen-II headers, I only picked up 11 hp and 7 tq and a horribly rich a/f (almost 11:1 at 6k).

Got ya. I understand about the shop and everything and you not being able to answer for them, makes sense to me. It looks like you should try to get someone closer to Huntsville than Nashville but they aren't that far apart.

Ouch, 11:1 is kinda rich. I understand. So you would want as stock a car as possible or very lightly modded? That should represent more of the .org community than most anything else.

Thanks for the reply, man!

maximaownsyou

would the increase in height mess with strut bar clearance? just wondering...

6spd_Hayes

There are advantages & disadvantages to both locations. Nashville is better because there is a higher concentration of 5.5 gens (there are only two 5.5 gens in Huntsville on the Org). Don Napier has the experience in how they set up their testing on dynos with their product. He has also installed these gaskets on a 2k2 6 speed before (guy from Murfreesboro, but no longer has the vehicle). I am providing him the Engine Mechanical in the service manual for a 5.5 gen also (so he has all of the correct tq values and tightening sequenses and such). Only drawback is the actual dyno experience.

I would think a close to stock car would be the best (because it would have the most 'unfooled with' core). My car, being halfway heavily modded, has a whacked out tune (and I think it is resultant from using an early model 2k3 MAF instead of the $100 more expensive 2k2 MAF). But I digress. Back to the topic at hand.

6spd_Hayes

Well, that depends on several factors. Raising the IM up nearly a 1/4" could pose a problem with the FSTB. I know on 350z's it is a problem (but it is with all kinds of spacers, whether it is a NextGear IM Gasket, or it is the Motordyne 1/2" Iso Thermal plenum spacer). It is just a tradeoff. Some people actually place washers and spacers on their strut bars to clear raised intake manifolds.

epacy, i want to be clear on this one...this is a TWO set gasket system correct? one that goes between upper IM and lower IM...and the other goes between lower IM and heads? i just took a look at the 2002 maxima FSM and...

the installation doesn't seem that hard...removing the upper IMing isn't a problem for me (taken it off many times)....the lower IM is new to me...but according to the FSM, there are 8 bolts that hold the lower IM to the heads...everything should slide right off after that...correct me if i am wrong for those who have actually done it...

as for the upper IM, its cake for me....for those who never attempted it, you might get frusterated by some of the stubborn hoses and the two bolts near the firewall (so hard to reach)...

SoonerFan

iTrader: (5)

i have a FSM too and it looks like an easy job for anyone with the right experience and tools...if you can lower a car...you can install these

steven88

when are you coming back btw?

The set is comprised of 3 gaskets. One for each side of the heads, between the lower IM and the heads. There are two 3 chamber gaskets for that. Below is a pic that shows the location. <courtesy Studman>



The third gasket goes between the upper and lower IM. The same one that is replaced when you pull the upper IM for spark plug changes.

steven88

iTrader: (28)

thanks for clarifying epacy....i hope the installation won't be a bi+ch....but according to the FSM, its 8 bolts and it should slide right off...

I can't wait for dynos....when do you think it will come through?

Nismo3112

iTrader: (12)

You will also have to unplug the 6 injector connectors. The fuel rail I think u can leave bolted onto the lower.

steven88

iTrader: (28)

oh yeah, forgot about that...damn i hate freakin electrical connectors...some are a PITA to remove...i wonder how stubborn these injector ones are

Epacy

iTrader: (6)

No problem. It doesn't sound like the lower install will be that bad. Someone needs to make a write-up. Perhaps 6spdHayes or the Maxima owner they got to do help dyno could make one as Nextgear installs the gaskets.


And speaking of the dyno....I am not sure. I have not heard from Don in about a week after I sent him a couple emails.
6spd said they were going to do them before Maxus, so that time is approaching. Any info 6spdHayes? Is Don still around?

steven88

iTrader: (28)

when is maxus anyway?

IIRC its the first weekend (like the 3rd) in june. So its only a couple weeks away

Nismo3112

i got another question....do these thermoshield gaskets actually replace your old steel gaskets? or do they mate together?

SoonerFan

iTrader: (5)

pretty sure they replace

Epacy

iTrader: (6)

Yes
