sooooooo? arnt the 2tock intercooler systems single pass already

 

stock is 4 pass.

 

subd

 

Stock = 4 passes through the manifold, coolant enters in one nipple on the stock endplate, makes 4 passes back and forth through the manifold, then exits through the 2nd nipple on the stock endplate.

Dual Pass = Only 2 passes through the manifold, coolant enters through both the stock nipples on the stock enplate, makes only 2 passes through the manifold, then exits through a 3rd niple drilled into the center of the stock endplate.

Single Pass = 1 pass through the manifold, coolant enters through an aftermarket enplate on the passenger side of the manifold, makes 1 pass through the manifold, and exits through the stock enplate nipples on the driver's side.

FYI, $400 dollars is a very good price for a single pass manifold.

 

Price is good... Waiting on pic's and how-to as well as if their is a core charge discount for sending in our manifolds..

 

hmmm wonder what kind of flow rates they saw (increase/same/decrease) and overall performance gained. If significant enough this could allow us to push the tvs/m62 harder and without temp issues

 

SUBd not a bad price!
ANd yeah same bout the core charge!

 

i am still wondering if for the time and money if the dual pass end plate + option b is worth it. i can get the end plate for $120 shipped and the option b for like $120. so that's $250 in the hole + half a day or more installing it. Gains?!?! worth it or no?

 

i have my option b plus dual pass endplate plus smg fmhe still sitting in front of my tv here, but i would like to see what zzp has to say about this product ( not bashing for anyone keeping tabs )

 

This is the best cooling with the stock Intake manifold for a decent price if I was supercharged I'd hop all over this.

 

I would like to see some pics also

 

might be worth it if you had a pump that could keep up with the required flow rate, i doubt the stock one could keep the pressure up high enough to keep the top cores filled with coolant.

I am really interested to see how they did this as it should require a new/modified intake manifold.

 

The stock pump is perfectly fine as far as flow rate. I actually had to reduce the flow since the single pass gets rid of restriction and I needed to slow the coolant down a tad to help the exchange of heat in the manifold.

Some of you guys just spout **** out that gets others worried for no reason. It'd be better to do some research before talking. I haven't seen anything new pop up in a long time that hasn't already been answered on this forum.

Don't take that the wrong way.

 

I was actually just trying to figure out how to do this last month. I deemed that it was possible, so I'm interested to see how similar this will be to what I thought up.

Im making a single pass right now. Its not really much more work than making a dual pass.

 

post your results when you are finished man !!

 

can we get a diagram on howd this would be run? maybe some pics.....

 

I just installed the dual pass, option B and front mount H/E. Definately worth the money IMO. Other things to cool the intake charge but this doesn't require any tuning. IAT temps recover quickly.

 

Im going to post before and after IAT2 on a dyno run. Im sure the results with be very pleasing. Im already planning on making atleast 3. One for me, and one for 2 of my buddies.

 

sub.

 

I want pics and info from the seller

 

Any updates on this, I want to order for a dual passset up or possibly single pass
