Intake Manifolds

[razorlab]

If they care about IAT might as well run nitrous and meth to cool the IAT down in that 10 seconds, or run Ice box setup and bring ice and drain the water every pass lolll.

They do.

Now, now guys remember here on the forums we are.....

I am running this manifold in my car actually. It does very well keeping the car cool. I have 40-130 logs and track day logs that I can share.

My IATs are usually only 10 above ambient, and then after a WOT multi gear pull it goes up around only 15 degrees.

One important factor to consider is that not every car is the same. I have seen good temps with stock turbo 93 stage 1 cars, but that same car with a pretty maxed out stock turbo can’t handle the high charge temps.

my charge temps hit high 300 during track days after continuous WOTs, so best way to compare these manifold is to include Charge pipe temp in the logs as well.

my Charge temp vs IAT has more than 240F delta. My temps right now in 80F amb temp is better than stock mani 50F amb temp.

I'm leaning towards this manifold or going back to EOS. I'll do a little more digging before pulling the trigger.

To bad you

To bad you Didn't decide that you were just going to get another supra. You could have bought back your old car and had lots of performance parts.

I'm kind of glad I didn't. I get to start with a clean slate. Lots of new stuff out there. The only thing I am concerned about is waiting for parts, which I've been assured shouldn't be too much of an issue.

Shhh. if you bring up ambient, pre-manifold charge temp deltas and other nonsense like recovery time the 1/4 mile guys are going to throw a fit and yell "THE ONLY THING THAT MATTERS IS IAT" into the void of 8 secs.

Wagner is a dual pass core?

Psssh.. We always talk about degrees above ambient and you say that doesn't matter.

 

[zrk]

eah I understand what you mean. If they care about IAT might as well run nitrous and meth to cool the IAT down in that 10 seconds, or run Ice box setup and bring ice and drain the water every pass lolll.

We do.

CSF finally announced their new race intake manifold today. Single pass with -16ORB for icebox. Maybe this will compete with EOS, at least for us drag guys.

If they’re still using a csf core, it’s still trash.

They knew they shit the bed with the b58 manifold so on the s58 manifold they used a pwr core.

Chinese intake manifolds have appeared

Also cool that there's a B48 manifold out there.

Some more data from my Wagner Manifold from my last track day at Lime Rock Park. Running a spicier tune now with 27-28psi out the top and good for 500whp/500wtq. You can see in the log that my oil temps are now starting to get up there, even on a not terribly hot, but humid day.

In this session, I did seven laps at full attack, then did one cool down lap and then did another four laps at full attack. The car is fully heat soaked at this point. Here are those four full laps beginning and end, so you can see how well the manifold is at keeping temps consistent.

For comparison, my track buddy @garudathree was seeing 160F temps with a 100% stock 2021 ecu tune and 100% stock cooling.

Lap 8

Lap 9

Lap 10

Lap 11

Saw this for the stock intake manifold, be interesting to see how much this works.
Idk how much heat actually transfers onto the stock plastic.

Again its been proven to work if you look at the history and evolution of CSF manifold. Getting the intake manifold off the block is common sense to reduce heat and heat soak.

Put your hand on your stock manifold, does it get hot enough to burn your hand? If not, the spacer probably won't help.

Teflon is basically just a fancy plastic polymer btw...

Installed a Wagner manifold today, spent a decent amount of time making lines to reroute the evap under the manifold, also rerouted the engine harness.

Note: if you plan to use a phenolic spacer with a Wagner manifold you will need the following:

-Light modification to the manifold is required for additional clearance to the cylinder head
-Spacers/modifications to mounting brackets
