secondary heat exchanger??
I'm curious to know if anyone has ever thought of adding a secondary heat exchanger, VRP speed sells them. And would it make a difference?
I live in florida the heat here is crazy plus I have a clutch-less pulley 74mm and it produces a lot of heat. I will also add meth one day when i get around to.

I've heard of people doing it, not many that have said it makes a world of difference. It probably does help, it will add another restriction for the IC pump and I wonder what that does for the life of the pump. But it will effectively increase the fluid capacity and should help in theory.
Where are you going to stick it?
Meth will be definitely a bigger help than anything really. Do you have a bigger cooler in it already?

I had an extra HE on my SL55 with a bigger pump and split tank system but took it off and plugged the factory HE and installed a Killer Chiller with an isolator valve. I have a temp sensor in the tank and other than after a good stab at the throttle, my IC water is always less than ambient temp. No matter how many HEs you have the coldest the water could even theoretically achieve would be ambient.

Yes but if you want to daily drive your car worry free you should probably just stick to air to water heat exchange.
I like the idea of a KC though... just don't have the budget/free time to learn that system (not sure about OP)

With a 74mm pulley?!?! That's crazy talk. 
My thoughts would be skip the secondary and go straight to a big ol trunk tank full of ice, or meth. I would bet you still won't be happy with your IATs after the secondary any ways.
I just did meth with my 77mm pulley and with a big hx and cwa50 was.hitting 160 in the 1/4 mile. With meth in similar conditions and the same starting temps IATs are I'm the 90s the whole time.

I did my secondary with an engine bay tank at the same time but honestly I think it makes a big difference. Pretty good size and easy to install. If I had to do it again id do it 100%.

Can't find out until next year, track is done for the season :-[ With the 160 IATs, 1.8 60 fts, and the 77mm pulley/tune before meth I was running 12.5s at 6000 ish DA. I got the meth installed, to test it I drove around like a dick with meth off to get it nice and heat soaked, then did a zero to 110 pull starting at 117 IAT. Temps dropped into the 80s and peaked in the high 90s. Unfortunately I tried to log this pull and set the Torque sample rate to 0.1 seconds(from the 0.5 I was using before) to get a good idea of what timing was doing, but that must've been too much data for it and the log was trash.

At sea level? Or better yet, IATs at the end of the run, OAT, and starting IATs?
I'm not sure if you are implying that because you ran an 11.4 you don't need any more cooling other than the heat exchanger without any other information or just trying to point out that you go faster than me haha

Yup haha! 7 PSI peak stock. 10 PSI peak with 77mm pulley, and now I got 11 PSI peak with the pre-sc meth nozzle. Every one talking about 11 or 12 psi stock, makes me so jealous haha.

Yea that sounds right. I'm also running a 77mm upper and I hit 9psi peak. When i was testing nozzle at throttle body would increase to 10psi. Are you running headers?

Those are interesting timeslips. Your 1/8-mile traps looked like a car capable of 124-125 mph at the end of the 1/4-mile, but they didn't quite get there. Regardless, that 180 crank pulley is an absolute beast on the front half.

Also to OP, I also considered the VRP secondary HX, but mounting location on the E55 is limited. The way they have it on their website, it'd block like 90% of the airflow to the radiator which would obviously be stupid on a street car. Would there even be enough space with the airmatic pump removed to fit the HX in that cavity? It seems way too large.
