View Full Version : Trilogy owners, how about a lower pulley?

For those of you who have the Trilogy kit and seek more boost, I may have found a local company who will make lower hubs that work with the popular rings to increase boost. I'm trying to get my car to around 18lbs, either by moding a Metco hub to be the same overall height as the trilogy lower. In my quest, I have found a tool shop that would be willing to CNC as many as were needed. Of course, the more units made the lower the price. Basically I'm trying to guage the interest. Post up with your thoughts.

Yes, I have a fully built and balanced 03 Cobra engine bored .010 over with forged pistons. It should handle 700 to 800 hp easily. ARP hardware was used throughout the engine and the flexplate is SFI approved.

It would be nice to see the kit make well over 500rwhp without Nitrous. I say try it.

No nitrous and using the 3.0 pulley.
Haven't tried the 2.8 pulley yet! :D

Rich Long had these made up about 2 years ago. And as far as i know there are only 2 cars that have them (NATEHAWK & ME).

Ask Rick in Miami how much air you can flow through the inlet duct on the back of a Trilogy Twin Screw, IIRC, he said 15lbs was about max, too much restriction.

Yes, 18#'s is possible, but it's only for a short burst and is not sustained. It's especially true with the roots blowers, that they'll spike high and fall back down several pounds.
I've been trying to run a very high boost on my twinscrew setup, which unlike the roots, shouldn't fall-off after peaking. However, what I've found is I can spike pretty high, but I always end up falling back down to 13-14 #s; even on my 10.44 run.
The actual airhorn is the restriction at this point, not the blower or intake.

My blower and inlet has been ported, but I'm not going to advertise for the company who did it for personal reasons. I failed to mention I will be cooling the boost with nitrous. I'll be going forward and getting the quotes on Monday, I'll keep you guys posted.

02-20-2011, 11:20 PM
You would have to get the blower done by Posi for sure.
Going past 16-18psi with an M112 Really doesn't help anything. You can pick up torque down low but by the time it spins up with RPM it turns into a huge heat pump and looses psi drasticly.
The Trilogy kit is great but if you really want to take advantage of the engine you've got drew ya need to go with their TVS upgrade.
Will the Metco lower kit work?

Hello Rick-n-Miami,
I have the twin screw kit and was going to go with high boost in the future and was curious what you describe as the air horn as the restriction. What part is the air horn? I personally ported the black adapter plate and the 90 degree inlet part because I saw quite a bit of mismatch in that area. The stock throttle body is also a big restriction.:burnout:
Rick-n-Miami
02-21-2011, 06:00 AM
The 90 degree inlet and adapter plate are a big part of it, and also the horn shaped section infront of the inlet part (that attaches to the throttlebody). I also have a larger throttlebody.

Vortech, the metco kit will not work with a triolgy, the blower snout is shorter thus putting the belt closer to the timing cover
Michael
02-21-2011, 11:38 PM
Thanks for the clarification Rick, at least the horn can be ported for a little more flow if it really comes down to it.
As you may know you are running at 5 liters so the engine requires more air, your boost will be a little lower than with a typical 4.6 pulley combo.:burnout:

Has anyone contacted Metco directly to make some Trilogy specific hubs? Seeing as we're trying to adapt their pulley system, it would only make sence to see if they could make the hubs too. If given the dimensions required, it shouldn't be too difficult a task.

Yes, that was my first call. They said they do not make custom hubs. Even though they make the Trilogy pulleys, they can not take the measurements from Trilogy and make a hub. Jerry Barnes was not very helpful when I spoke to him about modding the kit. He told me who to talk to at Metco and what was about it. I'm sure he's not going to divuldge the measurements of the lower after the bracket duplication issues.

First off, the Eaton swap brackets are not DUPLICATES for the exact reason you mentioned. Design is similar, but the dimensions are different; so they're not duplicates.
Now that that's out of the way, would it be possible to pull a stock trilogy lower and get the measurements? May need to have a machine shop with a layout table and precision measuring instruments do it, but would be worth it. Could prolly then give that info to Metco for them to use for modifications to their current hub machining program. Would be pretty straightforward for them to generate another program that would cut hubs to the necessary dimensions.

So Drew, this is a custom hub that you can use with a Metco lower pulley, correct?
Drewstang
03-07-2011, 03:16 PM
Correct. This is just the hub, the end user will still need the ring pulley from Metco for their application. I went with a 6 lb just to see where it will get me.
Here is a pic of the hub:

Imp, it helped a little since I could show the guy what I was looking for and get in the ballpark on the measurements. If you'd like, I can send it back now that I'm done with it.

But there is only one Trilogy unit so I'm curious whats its max'd out limits are...

Would you be able to tell me how much further your newly made hub sticks out or moved in compaired to the old metco hub you used as a template. Could you put it on a flat surface and measure the difference or maybe the hub maker was able to tell you what they changed distance wise. Thanks:burnout:
