You may find that you will not need the 10,000 in the center as the Spider setup behaves like it has slightly thicker oil in it compared to the standard center diff.

Is that the VG you said you have a little over 2 gallons on it? From looking at the head you most be a great driver, as it does not look like it has 2 gallons on it. LOL Nice looking buggy.

I just about have everything to up grade my 8 to an 8.5. All I need is a center diff brace.

zJatoRad

yup that's it, no kidding, I don't like to show off or anything but I guess I'm a good driver lol.

You most be, as it does not look like there is a scratch on the head. I wish I could in 2 gallons have the heads on my engine look the nice.

zJatoRad

must be the hyper that doesn't flip much .

I have a question, in my Hyper 8 I used to run 7 - 7 - 3 which the center diff was standard, what should I put in my 8.5 in the center? more or less? to make it like it would be 7k? I've just never ran spider diffs.

I wish I could say I was a good driver but I am not and my Hyper flips quite a bit. [X(]

I never ran the 6 spider gear diff but like bentgear said I heard you run lighter with them.

zJatoRad

I thought it was the other way, so I guess I should use 5k? I'll just try that combo and see what happens =D

ProcessRacing

Yes, I think rc car action used 3-5-1 and they liked it.

ProcessRacing

I read thru the reviews on A-main and alot of people have been saying great value and steering, I just got to get rid of my revo stuff [:@] lol. One person with alot of drive time has told me 7-5-2/3 for the diffs. I am going to probably try this after stock settings.

I only have one more part I need to up date my Hyper 8 to an 8.5. Taking my time and only wining things on ebay when I get a real deal I should not have more then $125 in parts.

qbert110

hey i just got a hyper 8 pro off of ebay, what are they parts to upgrade to a 8.5? is there a list?

46u

My Feedback: (3)

FR 2 chassis
Longer center drive shafts (dog bones) for the longer chassis
FR2 center diff brace
Lightened CVDs
Lighten wheel hexes with full covered nuts
Front upper plate that holds the top of the steering bell which is longer do to the longer chassis.
Extened engine mounts (I have the King Headz so I do not need theses.
Front and rear big bore shocks and mounts. (I all ready have the big bore Jammin so I have this covered) I do have a set of the front Hyper 8.5 BB I got off ebay for $12.
Up dated much better radio box. (All ready did this to mine)
CNC front and rear arm holders
I do not care about the 6 spider gear center diff but might try one later.
That is all I can think of right off hand.

I got all my parts off ebay. I bid on many parts a month but only win a few as if I do not get them at my price I let them go. Got my FR2 chassis for $33!

zJatoRad

you got the front big bores for 12? man that's a great deal, also the chassis!

46u

My Feedback: (3)

If you only new what I paid for the other parts! Like I said I bid on a lot and only win a few but when I do win I normally get the stuff at a fraction of what it list for. The only thing I need to do the up date now is the center diff brace. Like I said I will more then likely have less then $125 in up grading my 8 to an 8.5.

Sorry if this has been asked before but, what's a baseline shock set up? Which pistons?

46u

My Feedback: (3)

Which shocks stock Hyper 8 stock Hyper 8.5 big bores, Jammin big bores like I run or something else?

dryvr

Sorry, Hyper 8.5 big bores.

46u

My Feedback: (3)

Sorry I have not run any of the Hyper 8.5 shocks yet so I cannot help. Have you tried to go to the Ofna forum?

dryvr

I'll go there and ask, I do visit that forum. I've been reading up on this forum though and have seen that you (46u) know quite a bit about the hyper 8. I'm interested in the 8.5 Are the 8.5 shocks bigger than the 8 and Jammin' shocks? Are there spring options besides the white springs that come with the kit? I will also ask in the ofna forum. Thanks.

46u

My Feedback: (3)

All I know right now is they are bigger then the stock Hyper 8 and even the Jammin big bores other then the newest ones that just came out. I have a front set of Hyper 8.5 shocks but have not done anything with them at this point since I have the older Jammin big bores.

zJatoRad

I just tried the stock 8.5 diamond tires at the track today and they worked very very good when the track is super dry, it won't slide at all, but once the track is humid and has traction, they will just push the car.

I love this bug, handles so good =)

thopper

What are you 8.5 owners doingwith the center spyder diff....replaceing,craming silicon in it, using the grease that it comes with? How does the spider work on the track?

ProcessRacing

Well since it has more gear surface area I have been told you could go a lighter weight then traditionally. You could start out with
3-5-1 or
7-5-2/3.

Hope this helps.

bentgear

Shocks will depend on where you run but on the 8.5 right now I have the white 4 hole pistons with 2 holes stock and 2 drilled to 1.5 40 wt in the front and 32 1/2 in the rear. Stock springs. Working good so far. Suspension seems to be working and the chassis staying pretty level. The 8.5 shocks are larger bores than the Jammin big bores but not as big as the super big bores they are currently releasing. Try the spider in the center before you change it out, you may find that you like it. Whiel mine has be completely leak free there are more places for it to leak compared to a stock center diff.

I found out that there are spring options for the 8.5 shocks. Blue = soft, Gray = medium, and White = firm.
