fabbing an intercooler setup... if one were to put an intercooler on a setup that didn't have one (just air-air) what specs would be needed to support about 520 HP? If an undersized intercooler was put on, would it affect airflow or just cooling efficiency? anyone using any "used" intercoolers from other cars???

Re: fabbing an intercooler setup... Gonna give a try eh? I think for the powerdyne you need to make sure you size your intercooler and piping for as little loss in pressure as possible. These little blowers don't crank out much air to begin with and you may find your 6psi blower pumping out a whopping 3-4.
I'll tell you what though if you can do it I think the results would be well worth the effort.
Rode keyboard in an ATI stage II car yesterday. IAT before boost 82, IAT during and after a blast showing 6psi on the guage.... 82! Very impressive. Same run on my car IAT's would be 140+ at full boost.
What are your initial thoughts on routing everything? Only thing I can thing off of the bat is off the dischage basically S down low enough for clearance for an intercooler sitting parallel with the ground then out of the intercooler curve back up to the top of the engine compartment and curve around into the TB.
Also a deflector of some sort to route air up into the intercooler would be needed I would think.

Re: fabbing an intercooler setup... what about a ic somewhere near the fenderwell on the passenger side. routhe the output of the supercharger straight towards passenger side. route the output of the ic back over the front of the radiator to the intake. (kind of like incon). Has anyone got the results from water/alky injection yet?

Re: fabbing an intercooler setup... here is a log I made the other day with water/alky.
You can see how the iat started to climb as I have about a 1 second delay before it flows at full pressure and then temps began to drop.
That was 11psi at 6000rpm in 2nd gear where I had to let off.
Cruising iat was 99 degrees as the blower was real hot and I had been cruising for about 45minutes.

Re: fabbing an intercooler setup... sweet 24 degrees of timing with 11 psi.
I should be able to run full timing with my measely 5psi <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

Re: fabbing an intercooler setup... SJH,
Two more questions for you, what was the ambient air temp? and what IAT were you seeing before the alky injection and at what PSI. THe numbers look real good. I used to see 140+ IAT's with only 4 psi and 85 degree ambient. Kind of wish I would have kept the kit longer, I think I would be looking into an alky system.

Re: fabbing an intercooler setup... It was about 80 outside and the hot blower under no boost raised that to 99 just before the throttlebody, as you can see in the log just before I went into boost.
I don't think my motor liked 10-12psi though.I'm already seeing more blowby and a higher leakdown on a few cyls after about 10 runs.
Even with water/alky 10-12psi is a serious gamble on stock pistons.
