Just what it says im looking for the low buck thermal intake gasket for a b18(Ls)
Who has the best bank for your buck? I saw a few no names on ebay for $30 shipped and im sure they are the same as hondata but has anyone had any problems with them?
-
Also, is Hondata really better as they say in this page?

Basically do the cheap ones get destroyed like that or are they full of shit?

I would like to see the res of the motor. I bet ya it fucking ran out of coolent and they drove it untill it overheated and locked up.......lol
-
It also looks like they left the stock gasket on and bolted this one on top.
-
chris may have those that are more resistant to heeat
-
I think he said he only had the dohc zc, and the 85-87 crx style ones. I already looked in his sale threads.
-
Yup all Im going to do is the bastard motors since there are way too many people doing it. Ill be doing old accords next and then the b20 prelude motors. The market is over consumed with people thinking they are going to get rich off making 5 dollar profit on a gasket.
Most people are using a very cheap plastic basically sheeted pvc. Any of the cheap white plastics gaskets are suspect.
-
I already did alot of redneck engineering with plastics+toaster oven
Stay away from the white material gaskets. Someday maybe Ill actually do a write up on my findings but thats the best advice I can give you guys in a short simple answer.
-
So what's better than white then? That's all I've seen, given I haven't looked too hard though.
-
blue.
Bisi has some too, but I think they are also pretty expensive.

He dosent have them for the b18a/b's

Low melting temp...
Melts at 347 degrees Fahrenheit. wikipedia posts in Celsius. if your intake temps are reaching 347 degrees you have a problem sir.
The white shit people use melted at 200 degrees in my toaster oven and gave off nasty fumes. Then crystalized and I shaped it into a ball with tongs. it has held that form ever since. The cheap white shit is basically pvc

Delrin smells like formaldehyde 8)

DELRIN PROPERTIES:
High modules of elasticity. High strength and stiffness.
Low coefficient of friction. Easily fabricated with hand tools and
automatic production machinery. Good abrasion and impact
resistance. Low moisture absorption. Excellent machinability.
Natural lubricity. Resistant to gasoline, solvents, and other
neutral chemicals. Useful in air temperatures of -60°
to +320°.

What's wrong with the vato zone paper ones?
-
i use to cut them out of 7 & 9 layer aircraft ply. fill the voids, paint it & done.
great for NA, questionable for boost
-

heat soak is a mother.
-
I have a used one if you want pay whatever it costs to ship it
-
god hondata is a joke. i have NEVER seen a cheap plastic gasket do anything like that. they indent the flange shape a bit but thats it.
this is boosted and n/a cars. seriously if the white ones melt your doing it wrong. :?:
-

Funny, as soon as I hit the gas so some air flows across the sensor, the IATs immediately drop to 25 degrees F over ambient on the turbo cars. Just as they should.

Well not all of us have turbo's and sitting at lights sucks.
-
It applies to NA cars, too. The ITB car on the dyno tonight was clocking 150+ IATs until I hit the gas pedal.
-
I've logged 135* doing 80mph....Then on the same motor but with a bisi gasket, logged 120* at the same speed and climate. Temps in the city didn't drop much going from stop light to stop light.
Maybe it's just H/F motors. I don't recall any D/B IAT's ever getting that hot.

i made mine out of 2x4
pine ftw

Everything I've tuned for the last two weeks, NA or turbo, hits 150+ IATs sitting still. 135 IATs aren't uncommon for 100 degree ambient temps.
-
Without intercooler, and having run the water tank dry, at the end of a pull I have seen IAT's nearly 300*. Keep in mind this was with ~55 psi boost, 2000* + EGT's (gauge stops at 1800) and 85 psi+ drive pressure. Water temps start to get a little hectic at that point as well, surprisingly oil temps were not bad yet, they were climbing quickly though.

anyone tried g10?

I don't think I've ever tuned at 100* ambient temps, too lazy. lol
-
It's probably a little worse than that. First, the dyno is in a still air enclosure that traps heat. Second, the dyno's weather box is a couple feet lower than the car with the shop's new setup - bet there's +5 degrees easy at my elevation.

i have...undersized cooling fan at DPU in Pasco....103* ambient, saw logs of 145* IATs with thermal IM and thermal TB gasket
ran a garden hose over the IC and the IATs dropped 30* though. back to back runs can do that when your snail is on the boundries of its efficiency though :noel:
