What intake manifold is that?

Bringing this back.
I just got my setup running maybe a month ago. And while tuning I am seeing crazy high intake temps. (peaking at 140 with a small water to air setup.)
What are you guys seeing for temps or doing to combat them?
I am going to build a resivoir first and check my pump is flowing correctly.
Then maybe some insulation/heat shields... and if I have to, a meth nozzel in between stages....
What boost pressures are you running?
Air-to-water setups have to be designed quite well to keep temps down for any length of time, but I really don't think 140 is any big deal if you're running E85.
Meth in between stages might bring temps down, but I doubt it will help with power much.
Tyler did some experimentation with pre-turbo methanol injection on his 16G car. It always made less power everywhere with it on. And his intake temps probaby hit 400* (no that's not a typo).
Woah! I forgot you had a 2.4. The amount of restriction you have built into the exhaust system with a 16G and HY35 coupled with the cast iron manifold and I bet you have a CRAZY hot bay.
2 turbo blankets ordered I will post my results.
Also should I look at ordering one of those 8cm housings for my 16g?
An 8cm would be good yes, but I think something bigger than the HY's 9cm housing would be of most benefit to the system overall.
Ya I was just working with what I had...
I will put that on the list of things to change out. I am sure the backpressure is unreal.
But I am not aware of any other options for the HY35 at this time.

Upgrading down the road to something like an open T4 19cm HX40 could prove especially beneficial on a pump gas setup in terms of the amount of boost you can run and how aggressive the tune can get, with little or even negligible overall penalty in response as the HP stage will breathe better (read: spool quicker) with less resistance downstream.
Clever waste-gating could help light the LP stage faster as well, taking advantage of the unmolested energy from the motor by-passing the HP turbine.
I'd just stick a HX35 with a 14/16/22cm turbine housing on it.
A larger unit, like the 60mm HX40 map, being wider at low PRs (dictated by fuel in this case) may allow him more room before running off the right hand side.
The HX40 is seeing the system of the 16G and the motor as basically just one large motor, and it will have demand flow like a larger motor when you plot it out on the LP stage map.
The bigger turbine would also help with being on pump gas.
Well, when your PR is too low and you have more motor than turbo what happens? Same goes for a compound system when you run a low Primary stage PR and engine demand puts you into the choke below what the turbo would be capable of on a smaller motor at a higher PR.
Math is never over-rated.. thats just how the world works.
There are countless examples of this.
How much power do you think you'd get out of an LS7 running a single HX35 at 7psi?
You will have a heck of a time pushing even 40lbs/min and the motor would fall on its face well before stock redline.
A DSM example is Kevin's car, 90lbs/min out of a 67mm at 4.0PR as a single, can barely make that much out of a 75mm at 2.0PR on the primary stage.
The primary stage is what dictates how much air the system will flow. If you don't or can't run it at a PR where it moves the most air, you are going to fall short.
