I'll get it dynod but it may not be for some time. I have a ton of other dynos and time consuming things in que. But when I do, it will be done in a manner that best simulates (or approximates) real world conditions. Dynoing the Iso Thermal system won't be as simple as dynoing a typical plenum mod.

Running a typical dyno with the hood open and a fan blowing on it for several minutes before the pull provides real results, but not real world test conditions. Ideally, it would be best to find out what the car does when it is heat soaked with typical heat soaked plenum temperatures and engine compartment temperatures.

I may be able to do a good approximation by creating similar pre/post "plenum temperature" test conditions.

The car could be taken right off a long freeway cruise, quickly slamed on the dyno with the hood opened just seconds before doing the dyno pulls. That would provide near realworld heat soaked test conditions. After doing three baseline pulls, install a MIT kit and repull 3 more runs. (But I can already tell you there will be some amount of gain)

Of course all other temperatures and variables would have to remain constant. Ambient air intake temperature, engine coolant temperature, transmission temperature, ECU and every other variable within reason.

Although I've done many, many research dynos there is always room for more. The only problem is my back is killing me from hours and hours of bolt turning over the engine while on the dyno. And I have so many more dynos to do for so many other cool projects. I love it!

I'm gonna have to get a dyno of my own just to keep up with the research requirements.

BTW,
Important announcement! The Iso Thermal system works on every engine, but the plenum spacers do not work on the 05 6MT "REVUP" engines.

I did pre/post testing of a plenum spacer on the revup engine and it did nothing. The test was fully controlled for all variables so I know the results are true.

Needless to say, I was disappointed in the results. This made me a little mad and I decided I wasn't going to leave it at that. So I set out to find a way to make power on the "REVUP" engine.... And its a good thing it worked out that way because I did indeed find a way to make very, very, very good NA gains on the "REVUP" engine. Details on this will be released in a different thread not too long from now. I'm working on production logistics.

I'll get you REVUP guys Reved up soon.

No on both!

Based on seeing many dynos performed on cool and heat soaked plenums,
For now, I will estimate the ~3-4 HP in California Summer weather. In cold environments it should do even better because the deltas and heat flux rates are higher.

The Iso Thermal system doesn't make power, it helps to prevent a loss of power as everything gets heat soaked. It essentially functions like a low level intercooler weather you are NA or FI.

Intercoolers obviously add power by making the charge air cooler and more dense. Conversely, the Iso Thermal system prevents power loss by preventing the plenum from getting scalding hot and transfering its heat into the incomming air.

So either way, its about reducing charge air temperatures.

Technically yes, but given the limitation in heigth that can be worked with, it is best to put the maximum amount of thermal insulation between the manifold and the lower plenum.

Besides, the manifold/lower plenum interface makes a great thermal choke point. There isn't much interface there so it make a good point to place the insulation. The upper and lower plenum interface has much more contact area. Thus any insulation will be much less effective there.

PS I am working on the Copper TB heater installation documentation now!

Thanks for the response. I found some background info and additional data on the Motordyne website. Doesn't the revup engine include a different intake manifold collector? That would explain the apparent lack of improvement on the revup engine.

Hydrazine...I enjoyed meeting and following up with you yesterday at the Turbonetics Open House. To all others I must say Tony is very commited to getting out product that is ensured to work as advertised and makes a GREAT product. I got my Motordyne 5/16" spacer and ISO thermal upgrades yesterday. These will be going on my car in the next week at which time I am going to arrange some solid pre-post dynos for it. Also I have got another turbo Z set up to do some before and after testing for Tony and he can also post results on his car as well. With two independent dynos of this on a boosted car you should all have some solid data with which to base your purchase. This time next week I think we'll all see that Tony has provided a great product that makes proven power and is reliable. Thanks again Tony for coming out yesterday. Hope you had a good time checking things out up there and I look forward to getting you some solid data next week.

Thanks Robert!

Can't wait to see the turbo results!

Tony: I looked around and did not find a GB; please post a link on this thread when it is set up. Thanks.

OOPS! I just looked a little harder and found the GB. Thanks.

I have a Crawford plenum . I need to run 3 gaskets to get it to seal properly . With the 5/16 in. spacer...will I still need the extra gaskets to get the plenum to seal ? Or does the spacer comform to the shape of the plenum ?

The spacers conform to the plenum very good.

Over 500 have been sold and sealing has never been a problem. One stock gasket on each side is all it takes.

So will I need to purchase 2 new stock plenum gaskets or does this kit come with them already? Forgive me, I just don't know any better.

Hydrazine

iTrader: (53)

No problem. It comes with a new gasket for the top side of the spacer and it uses your current gasket on the bottom side of the spacer.

Tony,

Are you going to post the installation instructions on the website so we can get a preview of what's actually involved in removing everything to get to the manifold?

Hi Dave,

Its already posted on the website.

Sorry to belabor this...So for us guys who already bought the spacer and are just getting the retrofit iso thermal kit can we reuse the two gaskets we have or should we buy two new ones for the best possible seal?

with what number do i get a hold of you guys? i called 661 993 5111 and i got a lady and her two friends...i have some questions i would like to ask over the phone, thanks.

Tony,

I reviewed the posted installation manual, but did not see any instructions on the copper isothermal option. It appears that both heater hoses are reconnected to the new copper plate? What happens to the old hose connection points? Are the old hose connection points on the manifold or on the TB? Between the bypass valve and the copper isothermal option, which one reduces IM temperature the most? If I just want the plate between the IM and the TB, would I order Item #2, Polarized Copper TB heater for $50? Forgive me if you have already answered these questions. Thanks

You can replace the gskets if you want to, but its not necessary. For my development testing, I used the same gaskets over and over and over. The Nissan gaskets are very good quality.
