So some decent runs iver the last 2 days.

The Difference between the HX and SC depends on outside temps.
Ambient 75* there is about a 6-8* difference just cruising
HX temp being 76*

Ambient 90* there is about a 10-12* difference just cruising
HX temp being 90*


On a WOT 0-80mph run the SC temps rose about 10*. So the difference was about 20*
HX temp being 90*

 

Excellent results from the HX getting the exiting coolant back down to ambient. I would have thought the coolant would absorb more than 20* under boost though. What are corrispoinding IAT's on the above runs?

 

Sooo things have been going fine with the truck so it is time to **** it up. Currently it is about 13.7psi (195kPa) @ 16* with 2x7 meth nozzles.

So i ordered the following

1. 2.5bar MAP sensor
2. 2x10 meth nozzle
3. 2.9 SC pulley
4. NW102mm TB new boost version


More than likely i will redo the i take tube to 5in depending on fitment of new TB.

We shall see how it turns out

 

What's the difference in the "boost" version? Does it use LS3 or LS2 internals?

 

I called and emailed that same question. This was the response.

I then called. They said they have sold alot of them and they have not had any issues.


Some research on various forums suggested the problem was not with the motors but with the plastic gears and the "fix" was to use metal gears. Which in my mind makes since because most issues i read about happen over time which means those plastic gears are wearing and slipping.

I have evey intention of taking it apart when i get it to see.

 

I hope it works for you!

I love the mod list! It's going to wake it up for sure.

How much timing do you run at 13-14PSI currently? I would think with more meth and more boost you dont even need to lower it.

 

Currently it ramps down to 16* @ 165 kpa and holds that amount to 185kpa at 195kpa it is at 15*

 

I cant find anything online about a "boost version" I have a NW 102mm and i'm curious if I have the "boost version" or the plastic gears.

 

Look on the corvette, camaro5 and ctsvowners forums. It is buried but it is there.

 

The only place i found that sells it.
