hondata is looking for a tsx to test fitment of a heat gasket. cmon honda ecu upgrade!

haha once again im screwed out of the cali offers

tuan209

Wonder wht are the differences b/w intakes and heat gaskets. hondata say it is about 5% increase in power so thats roughly ~10Hp gain. i think its a much better value than CAIs. i may opt for this.

accsuperstar

well as far as performance per dollar, the heatshield is supposedly better. however intake is still one of the best bang for the buck mods you can get so why not just get both?

Delmiroc

I would donate my car if they come pick it up in Florida

btw where are they located?

tuan209

actually i HATE modding my car. guess since im alil older now i dont really like lowering my car, adding intakes, and exhausts. I may or maybe not even do the hondata thing unless it gives the tsx som moree low end torque. kinda of odd that im even thinking about the mugen SS, but it does give it it alil sportier look, something along the lines of the stock IS and 3 series.

im glad to see hondata hasnt forgotten about the tsx!

I dont think you will see 10hp off this gasket...what you will see is a more consistant level of power with a small gain...maybe 2 to 3HP across the whole band. Not too bad for a $60 gasket.

Check out some testing results using the heat gasket. The second test was from me testing on a Civic.

Maxboost

Anyone ever had bad experience with the gasket before? I mean it can't be all good right? There has to be pros and cons?
anyone?

21_in_az

worse gas milage, would be my guess.

JTso

How do you figure? There isn't any bad things about the heat gasket except it's a little thicker (approx. 3mm + 2mm washer) so the stock studs may or may not be long enough. Certain applications require longer studs but most don't. The last I heard they have stopped shipping the gasket with the washers so it may not be a problem anymore. The good things is you never have to replace another intake manifold gasket, as it's reuseable and it doesn't need any sealant to install.

21_in_az

your big words dont scare me! i laugh.....hahaha

more hp=less mpg.......simple fisics man.

JTso

iTrader: (2)

I'm sorry that you are so misinformed. It all depends on how the "more hp" is achieved. If you drive a car that's not tuned correctly, then I agree it will use more gas for some hp gain and probably buffing smoke everytime you step on the gas. However, if the car is tuned correctly, you will not have that problem. Try talk to some Hondata users or tuners and see what they say.

21_in_az

oh, sorry i didnt know it was possible to tune a heat gasket.
my fault.

ClutchPerformer

This is true, but I think 21inAZ may still be right overall. I've never heard of these heat gasket things, but it sounds like all it does is lower the intake temperature. If that's the case, then your intake air will be more dense, thus more air per intake stroke, thus more fuel at the same A/F ratios. So, all things being equal (tuning, etc.) this thing should make your MPG drop. Right?

21_in_az

yup.

JTso

iTrader: (2)

Not necessary. For an OBD2 ECU (which the TSX has), as intake temp decreases, fuel increases, as well as ignition timing. The engine behaves a little peppier with less throttle. Don't get me wrong, the gasket alone is not going to make the car faster. It's just one of the components that compliments other mods that one would add their setup. It's just like the Hondata reflash that enhances the typical intake/header setup.

ClutchPerformer

Gotcha. So you're both right!

21_in_az

common sense says that when fuel increases, so does mpg.

were not talking alot worse, like 1mpg worse, maybe 2. i was saying that the ONLY con to doing this mod is that you will lose just a little mpg.

ClutchPerformer

Right. But Jtso is saying that the fuel use is cancelled by the extra power (you don't have to open the throttle as much to get the same response).

21_in_az

your still using MORE FUEL! no matter how you look at it, to gain the hp it claims to provide, you will lose some mpg, period.

TinkySD

It's all about raising engine efficiency. More power can be had with better mpg if the mod increases the efficiency of the motor.

Now while i don't think the gasket will give you any increase in efficiency something like a hondata ecu tune can.(it's used in conjunction with a CAI)

It is correct however that with an i-vtec system you can feasibly get more power(more advance) while using the same or less amount of fuel. The change in temp in this case probably isn't enough to have this effect but it is possible.

JTso

Haha... I don't mean to pick on you but yes, Hondata used to sell heat gaskets that you can tune. It's call standard gasket and race gasket. I have the race gasket which blocks off the coolant that flows through the intake manifold. Since hot coolant is not flowing through the intake manifold, intake air temp is lower. The race gasket can be modified (tuned) to become a standard heat gasket by cutting an opening to allow normal flow of coolant. However, I don't think the TSX has coolant flowing through the intake manifold.

Here is pic of a race gasket and the cut out area.

i am more interested in their ECU upgrade than the headgasket. yes, it's nice. but i am not sure how much diff it will make for regular everyday driving. besides, i found it a pain to get it installed when i helped my friend to install his on his si hatch.

21_in_az

i cant wait untill both the heat gasket is out, and the reflash!

combined with the vafc-ii hopefully we will have the same power as a v-6 accord......*heres hopeing*

accsuperstar

haha i highly doubt it. that is over 30 whp and not to mention we would still get destroyed in the tq category

21_in_az

i know, but i can hope...right? and pray.

21_in_az

this is for 300, sorry.

Stokeless_TSX

400 whp is the goal i will achieve this one day..even if i dont get the hondata reflash...i can do it with just the vafc II if i ever get the harness...

21_in_az

and, im following stokeless step for step....as far as engine goes, not interior or exterior though.

JTso

Stokeless, I'm assuming you're planning to run some form of forced induction to get 400whp. Just a word of caution, once you are in the boost territory, you want to have the ability to alter the build-in ignition timing maps to avoid detonation. Being able to add fuel alone with the vafc II is not going to be enough. In fact, too much fuel can also cause detonation. Also, it depends on how quickly the boost builds up and detected by the MAP sensor, there is a good chance that "tip-in" detonation can happen because the ECU is still in closed-loop mode trying to keep the A/F at 14.7:1, regardless how much fuel you are trying to add. The trick is being able to get out of closed-loop mode sooner, prior to atmophere pressure. Good luck man!

TSX Cman

i cant see the tsx with 400 HP
think about how much the tires slip out as they are, you wouldnt be able to use all that power you just worked to get

tuan209

no kidding. a 400whp car should be RWD. ill be happy to get the tsx to 220-230 hp w/ 190-200lb of tq!

jiggaman

stokeless i would think that you'd be better off selling your TSX and buying a TL if that's the kind of horsepower you're after. save yoursef alot of money and headaches and blown engines.

I-MOD

Anyone find out when they plan to start shipping the gaskets?

gsclifton

iTrader: (2)

My shop quoted $300+ for the install. WTF?

They did not have an ETA for the product though.

I-MOD

Damn that is high! I only charge $75.00 to do them on RSX's

D.

Well, now I have another reason to visit VA, again

21_in_az

forgive my ignorance here, but how will the gasket cost?
