Just sharing some progress
 

Thought I would share some inter cooler work that I completed. All the information I have researched and received from this forum has been fantastic so before I start I just wanted to say thanks. So this is what I did.
Bought a universal inter cooler off Ebay and made it a two pass setup.Put it in the stock location. Took another inter cooler, a mini cooper aluminum radiator and mounted it on the drivers side behind the fog light. Of course had to remove the fog lights and put new mesh in its place.
I have two CM30 pumps, one pushes through the system and one pushes out so to speak.
Took the supercharger off and cut open the lower inter cooler removing the two side tanks. Cut the tanks off and made it into a two pass, dual feed , dual outlet/return setup.Never new it was a single feed three pass set up. Now I have cool water passing through front and rear. Also got a little crazy and stripped down the blower ,greased her up and welded close the two silencer holes and ported the inlet for a 82mm throttle body. This sucker SCREAMS under boost!! I love it.
So total end results..... Completely stock looking set up... unless you own one of these cars you could not tell anything different.
Temperatures cruising are at the same temperature as it is outside,highway only. When supercharger is engaged on temps are 5-10 degrees above ambient and an all out red line pull through 3-4 gear temps never go over 105 degrees on a 80* day. Works perfect. On a 70* day we had, temps stay around 95-100* on very hard pulls .So all an all.... $150.00 for the two coolers off Ebay and a lot of labor/love/welding and its a total win!! Unfortunately my camera card has disappeared so no pictures. I'm searching!! So thanks to all on this forum,.....

Sounds like a nice little project. It'd be nice to see some pics of everything.

I will let others ( The guys who are extremely well respected that know their crap inside and out ) comment. However, if you did what you claim you did to me this sounds epic.

I also have to ask "what are your credentials"? Are you an engineer by trade some type of hotshot mechanic?
pictures please.
tk

I like what you did with the intercooler. If you ran cold in on opposite sides, both banks should get about the same temperature air. I don't understand welding up two silencer holes. On my S/C, the silencer is one whole corner of the outlet blocked off with a cut down the middle. I almost cut it all out, but didn't want to listen to part throttle S/C whine all the time.

StarvingArtist the supercharger idea came from you in one of your post's a while back. Someone asked what the slots where and you said it was for sound so i researched from there.Also I know someone that cut everything out and lost boost so I did not want to do that!

Wow, those temps sound amazing! You do not even get hot enough for the ecu to start pulling timing. Your full advance all the way through a hard redline pull. That's great! :y

Pics would be nice, Congrats!

First off, I apologize...up front...on my questioning of this set-up!
Second off, awesome job thinking outside the box!

That defies physics on heat transfer? The water will be above ambient by default. How would heated water cool the intercooler core that is being heated by hot air and heat soak (heated metal to metal contact) to ambient temps?



*Other than having factory boost with ported heads and long tube headers with your intercooler set up.....this defies our factory blower efficiency.

Let me explain why I'm asking....

I have a 4 gallon intercooler system with 3 heat exchangers/ 3 factory sized intercoolers/ 3 CM30 pumps. With......

Ported heads (reduces boost)
Long tube headers w/o cats (reduces boost)
Intake that doesn't suck in engine heat
Single pass factory intercooler
3/4 intercooler piping
17-18 psi of boost

Results with 96 degree ambient temps...

-10 degrees above ambient at highway speeds with supercharger never engaged

-18-22 degrees above ambient at highway speeds (70mph) with heat soaked engine (takes @3-5 minutes to bring temps down to this level)

-0-140 mph WOT yields anywhere from 8-16 degree increase from starting IAT's (meth/water keeps me at to below starting IAT's)

As stated before, heat exchangers do little on helping IAT's under boost. It's the intercooler surface area. Again, please take no offense!











*if so, please disregard my above post. lol

Well I new this was coming so I will give it a shot than delete the post, not that it will help, so I do not stir anything up anymore LOL

"Temperatures cruising are the same as outside temperatures, highway only"

Why not? The supercharger is not spinning, just floating along with no engagement, no heat being produced and pumps running. The only heat being combated is whatever the outside temp is and whatever heat is soaking in the intake valley. It dose not have to defy physics because NO heat is being produced. The temperature will be the same. No? I may be way off with this theory LOL.

Next. "When supercharger is engaged temps are 5-10 above ambient"

Yes. All that is going on now is the blower is just puttin' along with really no load or compression of air because the engine is still in a vacuum state, no load very,very little heat being produced and just cruising down the highway with supercharger engaged. I always will say highway because that's where the most air is being pushed through the coolers. City driving..... totally different with little air flow and much higher temperatures all around.

If I am wrong than I clearly have posted a huge blunder and apologize. But my temperature gauge tells me I have gone in the right direction as compared to before this project.No worry's and thanks for the input Erebus!

I have a single pass Intercooler for sale in classifieds

Still don't understand what you welded??? If no pics, how about a sketch.

I had this done along with some material removal and porting. Do you see where the pencil is pointing? Those slots are there for the sole purpose of noise reduction. No gain in power if closed/welded.......just a gain in noise. Is it worth all the effort? Why yes, it's absolutely freak'in worth it. Sounds evil. Just say'in. lol



*Side note?

That shading on the outlet of the supercharger posted above was removed during some work on the blower. Finney played with this area years ago and I followed suit. Gains? .5-.75 psi gain across the board. You can't help to feel the increase of boost with the damn noise the blower makes. Placebo effect? Yes. No improvement in lowered IAT's, though.
