Also, 3 bags of ice is $6ish, which isn't a ton, but it's just another expense and logistic to track.

I'm honestly surprised by the number of people who are worried about inlet temps. As long as you're below like 180ish on E85 and 150ish on pump gas (assuming forged internals) it's fine. Don't worry about it and just keep going. Even above that it's fine for short stints.

Do you remember that I used bagged ice for YEARS in running XP, with never a complaint. I was always aware of the potential issue though, and at regional/ national events I would dump hot water into a bin under the car via a dump valve, then walk it away from grid a ways to dispose of it. It was nice having IAT's in the 90F range on boost. The funny part was in grid when people would notice condensation on my A2W intercooler and it was cold to the touch. I should have had it insulated, but never got around to it. Will do in the next iteration. Also, for full disclosure, I did run a radiator in the loop with a fan on it to pull a lot of the heat out. At some small events I never added any ice. The tune was very important, and very good.

I wasn't pointing fingers at you Sean I was referring to a few people that were local to me that did what I said.

I don't disagree that the air to water route can work very well. I just think it's a lot of added complexity in a system when it's not needed

Has anyone here tried the FZ-201? There's a soft 40UTQG and a medium 100UTQG. They're significantly cheaper than 200TW options. Size options seem limited 265 is the widest for the Soft and 285 for the medium. I'm currently running 255 RE71s though.. It seems like these could be faster than the 200TW street tires, based off a couple limited reviews. They're not going to beat Hoosiers, but they could be a cheap fast tire.

For those running surge tank what is your setup looking like? What brand and size surge tank do you use?

I'd like to be able to run low fuel level and easily empty my fuel tank to swap fuel type between Ethanol and Pump (car is still use in street). I was thinking installing 2 lift pump (DW makes nice one) on each side of the saddle tank and using the current Walbro 525 in the surge tank. Radium makes a nice single walbro plug and play one.

Personally I went with Radium's triple surge tank with a single pump installed for a few reasons. Increased capacity over the single hanger and the fact I can have at least 1 unconnected pump sitting in the surge tank incase the first craps out during an event, track weekend or when I'm driving it on the street and when I spend $$ on modifying my racecar I like to "future proof" it as well for when and if I need to run more pumps in the surge. I'm running a DW200 lift pump in a modified STi hanger in a STi tank (this is in my swapped '98 RS) with a Radium venturi jet pump kit and then a Walbro F900000274 pump in the surge.

As you can see in the pic below I'm also running a pre-surge tank Radium fuel filter (100 micron) and then I also have a post surge tank, pre engine 10 micron filter in the engine bay. Lines are Goodridge G-line XF 811 6AN braided stainless lines for complete SCCA/NASA compliance and there is no fuel smell whatsoever. Like you mentioned as well this setup made it super easy recently to "completely" drain the main tank and surge to switch to E85 while on the dyno.

Quick question on surge tank. I'm installing one in the trunk near the passager seat (see picture). Does the requirement for a "metal bulkhead" in section 3.3.3.B.27 applied or not?
