Stock C32 heat exchanger question
With my SC'er project in the works I'm going to need a H/E will a stock C32 H/E be enough to do the job if i'm only going to be running 6-8psi of boost? Jturkel has one and was thinking about taking it off his hands, I just want to make sure thats what i will need. Just following Moosejaw's advice and consulting my mbworld tribunal before i make anymore strange purchases.

If it were me I would go with the C3P HE and a CM30 pump. If you want a stock pump and/or HE I still have my stock units laying around. Actually I have 2 stock pumps now that I think about it...

If you're trying to do this as cost-efficiently as possible, you likely could go with the C32 stock HE since your boost level will be so low. That said, if you're going through the effort to bolt in a HE and pump in the first place, why not go overboard and get the better-than-stock aftermarket parts like the C3P HE and CM30 pump? More cooling efficiency will only help you make max safe power... can't hurt...

i would go with the e55 model. since you have higher compression and higher displacement then a c32. your going to be netting higher hp numbers even with the low boost.

Hooleyboy - my $0.02: ask C3P for their recommendation, and/or your install shop. GL!

It really isn't about HP numbers though, is it? It's about controlling his IAT's and what size of a HE core is needed to efficiently dissipate the heat from his IC. Renntech advised that he could get by with a stock C32 HE (saw hooleyboy post that somewhere) due to the low boost. C3P C32 HE would already be a substantial upgrade from that, and we know it definitely fits in the front-end of a w203. Buying the w211 E55 HE and then finding out it's a fitment nightmare wouldn't be fun for anybody...

his he has more displacement and compression then a typical c32, you can assume he would be displacing more heat as well. Also considering the c55 uses a clk front end, there not guarantuee that the fitment is the same as other w203's.
if the fitman isn't the same as the other w203's then he's going to need to redrill the holes anyways. Why not just go with a exchanger that can offer the lowest iat's if the amount of work is the same for both exchangers.
you also have to consider if he wants to upgrade to greater boost in the future. makes more sense to just to maxmize your cooling mods now.

It would be prudent to see if the E55 HE even fits. I can see Tremjins point on maximizing cooling while you're at it, but I think the C32 C3P HE and upgraded pump IS nearly maximizing the cooling needed. And as mentioned, at least the 32 upgraded HE is an easy fit. Not to mention it cost significantly less if memory serves me, although when it comes to stuff like this I don't imagine cost is that much of an issue or concern.

Saftey is the main issue. This supercharger puts out far to much boost than i can use. So I'm looking to keep the air as cold as i can at a safe boost level. IF I can get away with a stock H/E I will do that. IF a C3P H/E is what I should use then I will do that. I kinda feel that overkill might be better just to be safe. However if its not going to make a difference because i'm not going to be using the stock heat exchanger out of its efficiency rating than I will do that. I'm always up for keeping cost low but not at my cars expense.
