Gents,

Sorry I didn't get a chance to dyno the PLM headers like I wanted to but I had Benzworks install them plus a 180mm crank pulley, new intercooler pump and a canned OE tune. Car (CLS55) definitely feels faster and there is a noticeable difference in sound, but feels slower then my 04 E55 with EvoSport shorties+S/C pulley+can tune.

The problem is that now the car hits a wall after 2 or so hard runs which I'm guessing is due to the stock HE. For those with experience, would it more beneficial to get a meth kit installed or just get an upgraded heat exchanger instead?

TIA

Stock HE sucks. Upgrade that first.

Also have you split the cooling system yet?

You're on stock heat exchanger with a 180mm crank pulley?!

boostiality

lol I deserve that. Yes a miscalculation on my part, I thought we would have had cooler weather by now and the HE could be put off till February. Guess not


black06: no sir, just the upgraded intercooler pump

RBJ: So meth injection wouldn't be able to cancel the out the effects of the stock HE?

RedBullJnky

Meth would cancel out the effects for sure. Just ask the few upgraded sc 55 guys. They need it. but there's a couple guys down south (where it's hot as hell) that are running pulley, tune, HE, and pump with no issues. Just make sure you split the cooling.

Split is certainly key.

My mods are in my sig. I had a larger HE and its still on the car but bypassed since I run a killer chiller, trunk tank and meth. Overall a good setup for street and high speed runs in Mexico.

I am running a 180 lower and the smaller clutched pulley with split system, Johnson pump, ec he, and trunk tank and would see a peak 165 in Houston heat. That temp however still pulls timming so I added snow performance meth and now I can hot lap the car over and over and the highest I have seen is 110. To answer your question though start with the he and do some logginging to see where you are at.

Thank you for the suggestions gents, I actually found a brand new Snow Performance stage 3 meth kit locally for cheap which is another reason why I wanted to hold off on the heat exchanger. The results sound fantastic from the meth, so I'll have them do that plus the split while it's in the shop.

Might consider Split system and Killer Chiller . Amazing for daily driving. 100 degree day my IATs are 50-60 degrees while cruising around.

Worth the wait

Meth cures all.

Meth takes some managment to tune and manage but is a nice set up, if you dont mind the extra work. If you do an H/E, you might as well do the whole system with duel pumps, trunk tank , h/e and split system. Most of us start with an H/E but then the addiction keeps us adding, so easier to just do the whole system now

The h/e with a good pump will probably be best because meth does run out at the worst times so better having solid cooling instead of chemical

If you're just running basic bolt-ons, stick with the h/e. No tuning, no maintenance, and unless you're racing longer than the 1/4 mile, it will keep you cool enough for your needs.
