Thermo I/M Gasket, worthwhile upgrade?

[dorikin]

I'm thinking about upgrading to a thermo heatshield intake manifold gasket (B18C).

Has anyone here changed theirs and do you think it's a worthwhile upgrade?

Which brands are there available and is there much difference between them. Or is there a recommended one or proven choice

And lastly do they all require extended studs? Would rather not change the studs if I don't have to

street car I would'nt bother

[fatboyz39]

Not worthwhile.

[SLOBRO]

^^^^ what he said ^^^^

[na-118]

worthwhile

[bennjamin]

its not an upgrade and not worth the effort for a road or road/race car.




For drag cars that are chasing 1/100ths down the 1/4 mile or at the track - maybe this mod will decrease intake temp. for hi po engines or big turbo/supercharged builds....


but a total waste of time on a road car.

No point to a race car either...

If SPOON uses them I will say its good and useful

[e240]

Isn't the Spoon one a Venturi (they call 'em ventuli plate..haha) plate? not a Thermo gasket..

The innovative Spoon Sports ventuli plate increases mid-range horsepower and gives added torque. The ventuli plate replaces the stock intake manifold gasket. It's unique design gives the air flow a more streamlined approach towards it's entry into the combustion chamber. Good for about an extra 6-8 midrange HP. Available for the B16A/B16B and B18C5 engines.

Not a thermal gasket - its actually a choke for the intake runners.
Spoon also has fluid resevoir socks and "high tension leads" - both of which dont do anything.

The Spoon "Ventuli" has nothing to do with thermal dynamics and gets mixed reviews lol

I was meaning,if thermal gaskets were useful Spoon would use them coz I trust their judgement


@ bennjamin

the high tension wire is low resistance and more robustly made so I think its useful and the res. covers aid in soaking up spillage from boiled fluid on track

IM Heatshields as they call it.

It gives something like 1.5-2hp on a kseries. Where te manifold is right bang up behind the radiator.

I doubt it'll make any difference to a B where the IM is on the other side of the engine.

"Bisimoto Heat Shielding Intake gaskets which are designed with a special high temperature insulating gasket which replaces the factory intake gasket.
Reusable, this gasket isolates the intake from heat generated by the engine, allowing for a denser intake charge, and over 5-10 whp."

Noone with an n/a Honda should be scoffing at 5-10 WHP.
But that ofcourse, is if you believe Bisi?
He usually backs his products with Dyno Sheets.. So i'd say for $50 to my door, it's a worthwhile expense.
Besides it's reusable.. Saves you the headache of finding a new gasket each time.

5-10whp....on a worked drag car. Not anything else lol !

No.

On multiple, completely standard F22As.

5-10whp , lets call it 10kw at the *engine....thats significant for something overlooked on all production motors. I had a standard b18c7 which had no benefit from a thermal intake manifold gasket. Before / after dyno exactly the same.

Can you post up some more info for everyone ?

lolwut

derp. Typo. i meant engine.

[Jccck]

I'm no salesman.. Lol.
I googled it and found a tonne of info.

Shoot Bisi an emailt though, i'm sure he'd be happy to mail you some info.
And from how i see it, for $50.. Any power you gain is cheap and effective.

[bennjamin]

a quick search agrees with the bs statement as i think too -

If you honestly believe that an Intake manifold at elevated temperatures is honestly going to effect ~ 230L of air in one second (7000rpm x 2L @ atmos pressure) then you should really go back to school/college. Not to mention air has almost the worst thermal conduction value for heat transfer...

http://images.ibsrv.net/ibsrv/res/src:forums.evolutionm.net/get/images/smilies/smile.gif

I completely agree with this. Air is an insulator, with a thermal conductivity of about .024 W/mK. Aluminum, in comparison, has a thermal conductivity of 250 W/mK. The amount of air moving through the IM at WOT has no chance of heating up if the IM is at a higher temp.

There was a similar question in a related post where someone was asking about his hot IC pipes and whether they would affect his IATs. In short, no, they won't. At fast moving air conditions, there simply isn't enough time for a poorly conducting air mass to transfer the heat.

Mythbusters!

I would only purchase it if you fiddle with your engine alot and want a reusable gasket.
