This is for a SC kit. I was wondering what you guys thought on the 2. Since there are no Intercooler kits available, it would cost roughly 1 grand for a good set up. The water injection kit cost 500 dollars. Any input would be great, thanks.

 

I had an intercooler on my turbocharged car, it increased horsepower
about 10%. They work well on turbo charged cars because the turbo is exhaust driven and the air is heated by the turbo housing. Not familiar with intercooler on supercharged cars?? No experience with water injection.

 

The intercooler will give you solid gains with higher level of boost, read that as non stock. The watter injection will only be above 4500rmps.

 

Here is the product i am talking about:

as opposed to a custom intercooler setup, this is much more affordable but since its from their website, i guess its all sugar-coated and gains arent practical.

 

This is what Jane and I have: http://www.aquamist.co.uk

 

Hmm good to know : I am going to be taking the “route d’insanité à la Y2KevSE” – yeah Kev, you were right.. more boost is good and I need that 2.87” So I’m looking into this too... I didn’t know a water injection kit would only help beyond 4500rpm, but I think it might be a little more cost effective compared to having an intercooler setup done; it should be a few hundred bucks less at least right? Also, you won’t be seeing enough boost to worry about things below that mark anyways...or will you? I know it would *help* but still it’s not as much a safety risk as the driver

 

An intercooler is the better choice.

The WI makes the air coler by turning to steam when the ignition happens, it ocupies space in the combustion chamber so it really negates the cooler air effect. The usefullness of the WI is as a anti detonant, it will increase detonation threshold so you can run optimal timing.

What does this mean for a SC max? Until you pass 10psi WI is usless and will cause you to loose power because you will not detonate up to 10psi if your AFR is tuned right and the motor is in good shape. After 10psi it will stop some detonation. On a stock ECU max with no J&S it MAY allow you to run more boost, buyer beware. I will be using my DIY WI kit in a few weeks when I dyno tune. I have the J&S so I can see the detonation and if the WI is helping control it. With no intercooler I retard ~6deg of ignition timing on my way up to 15psi, 1deg per lb of boost starting at 9psi. if I can crank all this timing back I should get a sizable torque gain, perhaps 20ftlbs.

A well designed low pressure loss intercooler on a SC Max will help make more power just from the colder air at all boost levels. FMIC's are not recomended because all the plumbing and tube bends will cause a large boost loss, 2-3psi, which will negate any gains from the cooler air. I would prefer to have an AWIC, the boost loss is usually under 1psi and if you use ice at the track yo can get below ambient air temps BIG POWER!!! AWIC's are more complex because of the wiring but the cost should be about equal to a FMIC and no frame modifications are necessary.

 

I agree that an awi is the best route, although the front mount shoun't lose 2-3 if done right, mine did at first, but after the problems where fixed, it no only loses 1psi.

 

What core did you use?
How many 90 degree bends are in it?
Show those pics again please?
What intake temp drop did you see?

 

It's a custom griffin core.

1 out of the blower, one into the top side of the intercooler, one out of the side down to the ground.

Thats all I got for now, if you want I'll take some more when the car is finished being repared. But for now thats all i really have.

Don't know didn't measure it exactly, but It was noticeable just standing in front of the engine on a hot *** day.
