I am now running the Mechtech turbo system. I want to run more safer boost, will a bigger intercooler help out?

I emailed AA and asked how much for their intercooler with their brackets, they quoted me 1250. Is dat rediculas.

Cant i just go with a Skyline or Silvia intercooler?

That price isn't really ALL that bad, if you do try to go with a different intercooler not specifically made for your car you will have to do a lot of custom brackets, piping, bends etc. Pipe bending is the biggest thing, you want a mandrel bend if you're going to be running nay kind of high boost but it will cost A LOT of money to get a custom mandrel bend. I say just go with the AA intercooler.

A custom intercooler can be made in SoCal for about $750 day in and day out. Look around. The core is off the shelf, it's just the end tanks and piping that's custom.

Does anyone know a good place to get a custom intercooler in the Bay Area?

this might help but I don't know my CA geography very well. http://www.spearcointercoolers.com/

Yeah dat place is down in So Cal i found out. Thx

Still the ? for Bay Area.

i got my endtanks made at speacro. And im using a silvia core...there is definately a difference in spooling. Its worth the upgrade and should run you no more that $700 for the IC with endtanks. The skyline is way to big to fit in your front bumper

Bump!

I know RMS makes an after cooler but it just doesnt look big enough to really make a difference and there isnt alot of room to make it any bigger. I know ESS made an innercooler for their E39 line that has a huge radiator in the front bumper.

What to do you think about a spearco setup for an SC?

The RMS aftercooler uses water to cool the air. The water is then pumped through a heat exhanger mounted in the front of the car. Its small cause it doesnt need to have air passing directly over it. Works good in my opinion. I dont notice much performance drop when it gets hot

How much is the aftercooler from RMS? And can it be adapted for other SC kits? And which one is worth more? The aftercooler or water/alcohol injection?

willy: the aftercooler is way expensive. Retail is like 3K. I think it will work with most kits.

injection is cheaper, but its more "maintenance" Plus, if it ever fails and you dont know about it......

RMS wanted $2000 for the AC i think. Their website doesnt help much either.

I think the water/alch would be the better bang for the buck

damn.. :eek: doesnt this forum move quickly.. :)

Its the Mod Bug..... I caught it damnit :b_blue:

Im up late looking for best prices for eibach sways.... Sigh...:embarrasm

I think the water/alch is probably your best shot. Let me know if you find a system cheaper than AA's price. $1100 seems steep for what it is.

everything for a BMW is steep for what it is.. u think $300 for ACS pedals is worth it?? :D

hehe...Willy you're askin lots of S/C questions, what are you up to?? :stickoutt

I'm also curious about the adaptability of the RMS Stage 2 kit to the Dinan S/C. Would be nice to hear from someone who's done it to find out for sure what's involved.

I have a apex skyline intercooler if anyone is interested.

A larger intercooler can't hurt, but you'd have to take some measurements of your current system to determine if it's really worth the time and money.

First, you have to determine how much of a pressure drop your current intercooler has. Measure the boost at the entrance to the intercooler, and at it's exit, at redline. If the pressure drop is greater than 2psi, then I'd say the IC could be optimized.

Next, you have to measure the efficiency of the IC. This involves taking several temperature readings before and after the IC. This will tell you if the current IC is efficient enough. I suggest buying Corky Bell's book "Maximum Boost". It outlines this procedure and has the formulas to calculate efficiency.

If you do determine you need/want a larger IC, check with Spearco. That's where AA gets their IC's from. Their current Stage2 unit uses the 7.8"x3.5"x20.0" core. You can probably get it directly from Spearco, with end tanks, for less than $800. Just make sure the end tanks are designed with air flow in mind, cause they contribute to a LARGE part of the pressure drop of the IC.

I agree with NickG, specially about Corky Bell's book, specially if you are just about to take a plunge into FI. It will definitely make you a more informed buyer.

The aftercool by rms would be much safer than the water injection if you plan on running high psi. If you just want to prevent heat soak then the water injection would be more cost effective.

buy the kit directly from aquamist, retail is 475.

Jason: Did u getmy PM?

Anyhoot the $475 is the pump alone. The tank? wireharness?
Accumulaters? etc.. etc.. tons of work needed..

If you guys can live w/regular water washing your windshield go
ahead on do it. I like my window washer concentrate. Besides
everytime i look at the engine bay of a turbo/sc car with a w/a
kit it pursuades me to eat italian that night.

I found this on the web it looks very similair to the AA kit. Its probably alot cheaper also since its for a ford focus.

That is the aqua mist kit, but like TKM3 said you will have to do some custom work yourself compared to the already prepared aa kit.

As you can see in my Sig line, Im using the AA aquamist system...But, Im still thinking about an aftercooler, which pretty much means RMS...While the winjection is excellent at suppressing detonation, and cooling temps in the cylinders, its main effect is to reduce the power loss due to heat soak...But thats not the same as Making Power...If you want to Make Power, you need an aftercooler. Some of the tech sites, like superchargersonline.com and vortecheng.comtell you that if youre not higher than 7 psi, an aftercooler will rob more power thorugh boost loss than it will make...But, Im not sure...when I had the out of the box Dinan kit, I swear that on hot days, I must have lost close to 40 hp due to heat soak...I dont know how much of that an aftercooler would have saved, and I dont know how much more starting hp it would have given me. But you can only count on winjection to save you maybe about 20 hp at the very max. Aftercoolers can do more than that, plus, it has the added advantage of Making power, which nobody claims for water injection!

Increasing the size of your intercooler will not impact the "safeness" of increasing boost. And while lowering your chage temperature, and increased intercooler will also reduce your low-end response. It's a balance you have to work out.

But as for your original question, let me modify my answer. While lowering the temperature of the charge will impact safeness of boost inasmuch as PV=NRT - remember that one? - but only at a secondary level. Pressure is the key ingredient, and you need internals and plumbing that will handle it.

My Viggen is running a Garrett T4 and I originally went to a larger intercooler, but the tradeoff for spool-up wasn't worth it. My stock SAAB (Viggen Spec) intercooler works better.

i got an intercooler from spearco.. 700cfm air/air for my s/c for around 600$

i got mine done at SPEARCO, endtanks and core. Even BLITZ NA recomends SPEARCO intercoolers over their own. SPEARCO/Turbonetics makes custom ICs. I just did alot of measuring first, then did a drawing and a design of my own IC, then faxed it to them and after a week, they sent me an IC exactly how I drew them down to my own specs.
