I have tried a bunch of different things over the years to make more hp out of little Honda motors and have found quite a bit left on table by Honda. Heat in the intake manifold seems to be a big one. I have used just about every isolator on the planet and each has is goods and bads.
I like the Hondata but the material does crystallize after a while and there is a problem of vac leaks. I have even used an home made phenolic isolator before but even it transfers heat quite a bit. Delrin is a great product as a lot of road races will tell you to make self lubricating bushings but it is also a great heat blocker. I to satisfy my curiosity i built a isolator for my intake out of Delrin and it made a huge difference on the track car, it seals much better and is considerably more effective at stopping heat transfer from the head to the intake. Using an infer red heat gun i tested 4 types, Gasket " Honda"--- An e bay cheep version of the Hondata unit-- the Hondata unit and one i made out of Delrin-.
The Delrin one won hands down keeping heat much lower than the others. Or my inferred heat gun and two others lie..
So not liking the others on the market and mine being home made and not very attractive i set out to build a prototype which i then marched down to a friends place which owns a rather large Water jet cutter and made me a bunch of Delrin units for my street and track cars.
My track car has one and now so do two of my street cars along with a few other people i race with now I seem to have quite a few out there.
With all of the positive feed back i am getting i am rather shocked when people are approaching me i do not know and want to buy them.
I made a bunch because the sheet of Delrin i used was rather large and the nesting program uses the sheet efficiently so i ended up with a hell of a lot more than i was planning on.
One of the local guys who makes his living selling jdm stuff on line " of which i seem to always be buying for some reason" wants to retail them for me. So he has a few and seems to be selling them fast. I am rather take by all this and am thinking about making a few more products as well. Right now i have a set up for B16-B18c5 and another for the B18c1 GSR motor. I was thinking about some D series and even Ls motors later this month.
Any idea's or comments i value most of your opinions..

 

 

have you try profeb's one?

Cant say that i have, whats if made of?

 

It seems that you've only tested with the intake manifold gasket so far. Do you think there would be any worth gains with a full gasket kit such as the Outlaw?

Yep, and nope all at the same time. Its a Phenolic gasket , i have tried a phenolic gasket but not theirs. We had leak issues and were forced to run intake gaskets on both sides which make for a thick stack forcing us to use longer studs or compromise the thickness of the gasket it self. That was the one that worked ok but did not keep as much heat out as the Hondata unit even though it was thicker? I could also see where a fuel had begun to saturate it as well and would continue over time hardening the gasket and rendering it use less after a length of time.

We considered doing a throttle body spacer but down here in South Texas it does not get cold enough to really create cold weather problems so we just remove the cooling lines from the throttle body and IAC completely so the air that moving over the rather large throttle body super cools it as long as the air brought in was cooler that the engine bay. As a mater of fact at 60% throttle the tb was the coldest thing on the motor by 4-8%.....
If the coolant lines are still hooked up then all of this is useless to install since your piping heat to the intake and throttle body.

 

The test bed......

 

Or should i say test beds...

 

.....if you would make some of those gaskets without that coolant port cut out, I would buy a couple as well. (race configuration)

The first ones did not have the cooling ports in them but i noticed the motors ran warmer than the ones with the cooling port. My guess was a possible pressure build up at the head not to mention the fact that there were leak issues at high rpm from the pressure build up..... I can cut you some but i would not run them in any of my motors but that is just me and my .02.

 

So what kind of mileage (aka testing) has been put on these gaskets? It seems like a great idea. I wonder how many other materials are out there that haven't been tried yet...hmmm

My AN-R gasket did next to nothing, so as long as these have had thorough testing, I'd definately buy one.

 

I'll be installing the Hondata IM gasket in the next week or so.

My track car ( the Yellow CRX) has had the prototype on it for 14 months and i have had the intake off more times than i can count. ( the car runs a ported/ polished type R intake on a B16 a1). So i know that they are reusable at least that many times.
My street Type R has had the newer one on it for 4 months and the intake has been off only twice and i have never had to go back in an re tighten it up after the initial torque.
As for if they work they have done well on my motors. I really am not here to try to sell these but more to get some feedback on what people are using and how it works.

 

I too am interested in how they are holding up. Next time you take the IM off snap a pic of the gasket. What kind of mileage on the cars?

Ever play around with Delrin?? The stuff is real hard to destroy that is why a lot of road racers " and auto xers like me " use it for suspension bushings over say polyurethane.
Self lubricating and tough as hell. Yeah the next time the intake is off of the track car " which has the hardest ife of all of them" i will shoot some pics.

 

I understand its hard to destroy. I've seen a hondata gasket after about 30k of hard driving and repeated use, I'd like to see one of yours, thats all.

 

So the only way that this gasket would benefit somebody though, is if they aren't running any coolant lines that go to the IM? What would be the negative effects of doing this in a car that I drive in colder weather (I live in NY)?

 

i have the outlaw engineering gasket kit on my itr motor, and to be honest with you, if you were to give me a car with and without the kit, and not tell me wich is wich, i wouldn't beable to tell the difference.

 

When the time comes, I would be interested in a B18C1 and B18C5 gasket. I'l check this thread for updates.

Please make me one. The issue you describe is only if you don't block that coolant port off the head; and run the line which used to go there into a T at the heater core line.....

 

This is actually really cool, the thing that turned me off about the Hondata kits was the wear that people were getting on them, and the outlaw ones were the fact that you had to also swap out all the studs and bolts and use theirs.

I'm aware of the durability of Delrin and am actually considering this, do you have any photos of the gasket used on the CRX to show how well its helf up to wear, not to mention being removed and replaced all those times?

Pix of yours please Rene M....

and I'll take some race config ones too.... B16A/B18C5/PR3 head

I'll even take a couple for SOHC D16Z6/A6 (I think they are the same...still SOHC n00b)

Any idea of what they'll cost your fellow ITR elitists?
