Question about HPI Aluminum Clutch shoe set
Sorry if this sounds stupid.
The set comes with two sets of springs, Silver and Gold. It says use the silver on s-25 engines and gold on the 4.6 engin. No mention of the 4.1 I have. Would it be safe to say that I can use the gold springs on my 4.1?
Since I am new to this and I am still learning the engines. I am assuming the S in the s-25 means small block. Am I correct? If I am correct, then since the 4.1 is a big block I should use the gold springs. Right?
Input please.
Thanks

RE: Question about HPI Aluminum Clutch shoe set
The "S" does not mean small block. The "S" means Savage. I'm not sure which is which for the springs but you can use either one on the 4.1. The stiffer the spring the more the engine revs up before engaging the CB and a harder take odd per say.

RE: Question about HPI Aluminum Clutch shoe set
Look closely at the springs, measure them with calipers if you can (diameter of spring wire), the thicker the spring, the later the engagement. A late engagement engages the clutch later in the powerband of the engine, giving you a faster take off, racers would do this. It doesn't necessarily cause undue wear unless you WOT it straight from the off, you can still build the revs slowly until it begins to bite and THEN give it some. Experiment...find what you prefer...

Use the gold they are thicker and made for the 4.6 but Im sure they would work great on the 4.1, you will be amazed by the improvement in the take off of your savage.

RE: Question about HPI Aluminum Clutch shoe set
I have found having the engine able to rev higher before taking off is an advantage because you can blip the throttle a little without the truck jumping around all the time, also the idle can be a bit higher without the clutch shoes dragging when you are stopped. I have not noticed any wear caused by late engagment. I do notice clutch wear from full throttle starts, is there any other kind?????? LOL...

Well we will see. I just threw em' on, along with a new Steel spur set and Racing CB. My dual brakes will arrive tomorrow and I will throw them on and then we will see what she's got.
And for the full throttle starts. Yup, no other way to go.

edit-Oh yeah, the included allen screws that thread into the shoes are only used with the gold springs/4.6 and up setups.

HPI says the golds are for a .28/4.6 engine and the silvers are for a .25/4.1. Use the silver springs with your .25/4.1. I'd stick with these guidelines for optimal performance. FYI-I'm using the gold springs and allen screws with my Axial .28 and this thing hits hard with that combo.

I still have to take it apart again tomorrow to add the dual disk breaks. Should I change the springs?
Also, How do I get the driveshaft off to get to the break assembly?
Sorry if the last thing is a topic jump. If someone wants to PM me with the info and stick to the subject thats cool.

RE: Question about HPI Aluminum Clutch shoe set
The dual disc brake set comes with instructions, follow them, I did, it wasn't hard...I kinda groaned when I realised I'd have to remove one entire side of the truck, but it really wasn't that tough.

RE: Question about HPI Aluminum Clutch shoe set
Remove the hex screws from the clutch. I used to run my S-25 with both setpus which means the silver and gold screws. With the silver the truck easily started moving on idle, its great for rock crawling but not for regualr driving. The gold springs are the way to go, my lhs guy told me the allen screws would put be too much for the S-25. Now I have upgraded to an STS .30 so I will be running gold springs with all screws on it. I cant wait till I start her up![>:]

I also happen to have a Savage X SS with a 4.6 engine. I also installed the Aluminum clutch shoes. I'm just curious of the screws being used for the clutch. What are the use of those screws? Are they used for weight or something?
Also, will it wear my racing CB?
Thanks!

RE: Question about HPI Aluminum Clutch shoe set
The allen set screws are used for weight. They make the engagement EARLIER, not later. I have the HPI aluminum shoes and I am using the silver springs with the set screws on my .25. I like them, and sofar have not noticed any fast wear, but I only have about 3 tanks or so on them so I cant really say.

The "S" does not mean small block. The "S" means Savage. I'm not sure which is which for the springs but you can use either one on the 4.1. The stiffer the spring the more the engine revs up before engaging the CB and a harder take odd per say.
