HDJ81 - HP Diesel Series 2 Intercooler Install & Review (1 Viewer)

[Jan-78FJ40]

I'd guess there was a leak...

I would agree with you guys if that was what he's seeing, but based on what the OP has posted he's seeing 2 PSI higher after the intercooler install. I would expect to see 2 PSI less after the intercooler install if boost is being read post-intercooler.

Oops, I missed that too. Not sure what would cause that.

As requsted:
A little pricey but very blingy and worth the money IMO to protect my investments. No point letting a new intercooler get gummed up with oil. Super easy install. Takes about 15 minutes. Comes with nice bracket, hoses, clamps and fittings. View attachment 1267055 View attachment 1267057Has a handy little dipstick for checking oil levelView attachment 1267059Plus the bottom unscrews making it very easy to emptyView attachment 1267064

Is there enough room behind that catch can bracket for a clutch master cylinder? Looks like it could be tight.

Love the writeup, becoming convinced I should get an intercooler as RTT really bites my acceleration and EGTs in the ass.

Yes boost guage reads post intercooler and is off the HP intake adapter. As mentioned it is possible I could have had a slight leak before installing the IC

I have not ruled out the cause being outside berometric pressure either. Not uncommon for the guage to read between 0 and -2psi at start up.

This is from Auberns websire:
"Note. Since this is an absolute pressure sensor instead of gauge pressure sensor, the
meter will not display zero pressure unless the absolute barometric pressure at the
sensor location is 1.00 bars (or 14.5PSI). The barometric pressure reported from
location weather station is the pressure converted to the sea level, or relative barometric
pressure. It is not the absolute barometric pressure at the local altitude."

really cool thanks for the pictures for the catch can. quick question is this the 2 bolt bracket or the 4 bolt bracket version? im just on hpd website and almost ready to pull the trigger!!!

Mine is the 4 bolt. As in 4 bolts hold brake master cylinder to brake booster. The bracket itself only uses two of those bolts. I'm guessing the bracket for the two bolt master cylinder uses both bolts but is obviously configured differently. Just check which MC you have

I will check the measurement for you when I get a chance

Adding this to the FAQ, nice write up and egt before and afters!

Yes, there is

Outstanding write up..here's a catch can, with removable bottom, and dipstick for $170..I guess the extra price for the HPD comes with the brackets..thanks for sharing..did someone mention group buy?

This may be a newb question but does post intercooler addition require any other work to be done? IE does it affect idle, timing, etc... on stock configuration and boost?

 

[Tapage]

Not really .. you might get some " lag " depending on your IC setup ..

Hmmmm. "Required" depends on point of view
Intercooler ussually gives you the opportunity to increase fuel, and boost an power output.

So, yeah a few small changes are definitely required!

 

[mudgudgeon]

@Malahki great job on the write up. Looks like a really decent kit, particularly for a bolt on kit.

My only comment is it looks like they could possibly have gone a bit larger with core?


That catch can is porn!!

What size is the piping on the HPD intercooler 2 / 2.5?

 

[BCR4619]

Just looking though this as I just finished a safari install, similar in some aspects but I like the route of the Safari a little better... I am running 8psi and 570ish F at 100 on the highway which is better than before, amazing how much heat comes from compressing air.

I was able to squeeze a 3/4" tranny cooler between my Intercooler core and AC condenser but man is it a tight fit!!

 

[Malahki]

What size is the piping on the HPD intercooler 2 / 2.5?

Yes 2" & 2.5" OD

 

[IanB]

Yes 2" & 2.5" OD

If it's 2.5" OD, it's got to be more than 2" ID. It's not quarter inch thick walked pipe. Probably just over 2.25" ID.

 

[serenity]

Just converted your egt figures from foreignheight to Celsius. 680 degrees before install, 557 after! That's crazy good!

I think he meant the inlet is 2" and out 2.5"
