I just received the thermoblock spacers from Outlaw Engineering. This was a complimentary kit from them for me to try out. I am very busy this week, so I'll install it next week and do some proper measurements of IAT etc.

Anyways, I opened the box and will describe the contents:

i. Thermoblock spacer for TB and Manifold
ii. 2x throttle-body gaskets (for either side of the spacer)
iii. 1x manifold gasket (the original metal one is used on the bottom)
iv. Several longer studs & bolts

The IAT guage and just a touch/feel of the manifold during warmed-up idle, cruising etc. will be a guage of how things are working. Given that my car is turbocharged, the results (temp etc.) might be a tad different.

 

if you show positive results, im sure the results would be even greater on a non intercooled sc car such as mine! glad to hear you got it and i hope it works out well as this is my next mod.

 

It definateley should help all CL-S's whether NA, S/C (non-IC & IC) and Turbo. Now, whether it really helps at WOT, not too much, but will definateley reduce heat-soak in the manifold and intake path leading to cooler air getting into the cylinders.

 

allmotor, do they come with any install instructions?

 

would a before and after dyno be out of the question? i'd be willing to donate some $$ for it.

 

True, but i was just pointing out that cars with setups like mine should have the most heat compared to even your setup. Ive noticed my car gets alot hotter than it used to when it was NA.
I remember seeing the S2000 getting over 10 whp and very noticeable drops in temps especially at idle, and it was pretty much stock! Ive been trying to locate the link (it was on a s2k forum), all i remember is the dude tested spacers (from hondata though) and had a very thorough review including temp measurements taken in two places along with dynos, with very controlled settings.

 

Yup, very nice install instructions!

 

I know this post is old, but were could i pick up some thermoblock spacers?

Installed my spacers about a week ago on my J32, tends to bring temps of the IM down one notch so the IM is almost never blistering hot, you can usually leave your hand on it for 5 seconds at its hottest, which wasn't even possible before.

I had IAT readings NA before on the J30, but I forgot what they were

The car seems to keep more of its daily driving torque as a result of heat soak being kept at a minimum and drag after drag seems to go easier since I can cool down the IM quicker.

 

^ This will be my next mod, the hot humid weather is killing my performance!

 

do the spacers really provide gains, or do they just restore lost power?
will they will work with mods such as cai, headers, exhaust, bc even though
its not that much $, 100 bucks is 100 bucks

 

Restore lost power. These coupled with the cooling mods kept my engine temps down a lot.

 

all of the cooling mods put together keep the engine nice and cool.

 

And my butt dyno showed great gains and responce in cool weather. I loved a 50 to 60 degree day when I was fully modded.

 

Not too sure about the low temp thermo stat, never had too much luck with it on my 3.0, seemed like it dropped my cars fuel efficiency as if it wasn't at optimal temps, anyone wish to comment on this? Meanwhile I just realized that in 84deg. weather im .3mph away from allmotors best NA trap speed

 

You are 100% correct. When driving around with an engine that is not at it's optimal operating temp, fuel effeciency and power will decrease.

 

So, it's not optimal for daily driving?

 

I am not talking about the spacers what so ever. I am simply talking about scenarios that would put your car at colder temps than it should be (i.e. running without a thermostat during a cold night). I do not speak of experiences with the thermo block spacers.

 

its fine. The loss of fuel efficiency is due because the vehicle is running cooler so a slight increase in rpms will be noticed. probably not enough that you'd even notice...

 

You guys know how those low thermostat work right? The reason you're seeing a drop in fuel efficiency is b/c the ECU sees that the temperature is not @ normal operating temperature. When this happens, the ECU will add more fuel hence why the fuel efficiency drops. My gas mileage was pretty bad during winter with the Mugen cooling mods.

Anyways, I ordered this for my J32 as well. Does anyone know if the TB gasket will fit with the supercharger? I only used the IM gasket on my J30 and sold the TB gasket. I thought I might give it a shot this time around.

 

^ So you'll only notice economy loss in really cold temps, not really hot temps, right?

 

Don't even bother with the TB spacer on a non intercooled compressed intake charge. I really doubt slightly isolating the TB from the SC heat will do you much good, since thats not your real problem but the compressed air itself. Sure you can give it a go, but your going to need the J32 TB spacer due to the increase in size of the TB.

 

Yeah, that's why I didn't bother the first time and sold the TB gasket. I thought I might as well use it this time unless someone wants to buy it. The motor has everything, even the VSA but that'll be removed.

 

Wait do you have the J32 TB spacer? If so I might want it since I still don't have one, I just have the IM spacer that I got from Siggy. VSA removal is a must

 

I will in a week or so. I ordered the kit from Outlaw a couple days ago. I'll let you know when I get it then. I'll have to sell my J30 IM gasket too.

 

Actually if you can since your getting the J32, you won't have the IM to hood clearance necessary for the spacers unless you completely remove the hood supports in that general area.

instead try rev racings 1/8" gasket, I think its around $30, and supposedly it works too, important part is that it won't raise the IM as much.

 

hey guys quick question.. do you have to use the stock manifold for this to work or would it also work with headers???

 

Has nothing to do with the exhaust system whatsoever, it goes between the upper and lower intake manifold, so yes you can use these with your headers

 

Blah, I already ordered it. You mean remove the black thing under the hood? I'll see how much room I have to work with without the spacer first.

 

I really want to get a new intake manifold, port and polish then get these spacers.

 

The hood insulation then you need to dremel the middle hood supports off the hood. Thats what I had to do at least

 

Would I have to do the same for a '01 CL-S? Or is it just a straight bolt-on? (I didn't see what type of car you have.)

 

No, I have an Accord thats why I had to do it
