i dont think you opend one up recently, here are three shimms ans i have a silver and a copper in the engine now. the closest i got with the calipers i have is .4mm. it dosent matter as long as its close i am only breaking it in with 20% and staying with it.
its all good

benzzyo5

after you brrreakin the egine and all, how many shimms should you have when your using 20%? one copper?

Sorry if I phrased it wrong but yes do not remove or change the shims till you have at least a gallon of run time on it.

jombo

thats just it, i copper is like .1mm and 2coppers are .2mm. with the shims i have or that came with the engine are more than .5mm. but the closest i got is a copper and a silver which is a little over .3mm.

One 3mm for 20%

benzzyo5

thanks!! so run one copper and one silver?

jombo

sorry 46u i'm going to be different, i am going to run it with the 2 shims for 20% and see if that makes a difference in breakin. in the directions it dosent say not to for breakin, it only gives recommended head shiming for the nitro you are using.

jombo

yes for 20% only a silver and a copper. but measure them to be sure.

benzzyo5

^^ if you have the V2 engine series then you have to break in the engine for at leased one gallon before moving any....you do because this engine is so tight that you need the shims to reduce the compession

benzzyo5

i don't have a thing to measure it.

jombo

i dont think you have that right or i may be wrong , i thought since your running a lower nitro content you use less fuel to ignite less compression, higher content (more compression) more fuel. isint that with full size cars higher octane more compression less compression lower octain.

I do not have a 30 or any 30 head shims but I just open a new pack of 28 shims and this is what they measure. One copper is .1mm, one is .2mm and the silver one is 3mm. Like I said when I got both my D21B engines they only had to shims.

So for 20% you only run the silver shim. But you cold run the .1 as wll to be on the safe side.

benzzyo5

i think i read that supertib was running one silver shim with 30%. but the .30 shims might be different.

i apriciate the help though...thanks

If you look at the explode view it shows all engine have one of each so I do not think there will be any difference. If you go to the link I posted above you will see. It plainly says as the instructions for ALL their big blocks are the same.
Up to 20% .3mm Will it really says under but I feel this is up to!
25% .4mm + or - .1mm
30% .5mm + or - .1mm
Now it is your engine so people many do as they like but do not talk bad about the engine if you have problems and do not fallow the advice of those that have been working with these engines for a while. The pinch is so tight and the compression is so great more shims during break in puts less stress on the engine.
Here is the link again.

off topic, but...

46u, I learned a little trick from my dad.

Never keep digital or dial calipers in your toolbox. if you have vernier calipers, nobody else knows how to read em so they don't borrow em

46u

My Feedback: (3)

So true as I have had people ask to borrow mine I hand them to them and they hand them right back. All so vernier calipers can take more of a beating with out getting messed up.

Hey all! I recently ordered an sts .30 with tuned pipe. Hopefully it will be here in the next couple of weeks. I would like to know if there is a clutch that anyone would reccommend to rplace the original. I will be putting it in a Savage X. Also if anyone who has run one of these engines can give me any tips and tricks for setting it up. Thanks.

HeatFire

Yes yes, allways seal your engine.. saves you alot of time if it leaks to already have it sealed since you dont have to clean it out either


edit: maaan, alot off time waiting for USPS to show my package on their tracking system.. want my engine nooooow... god bless USPS

BCKoots

Great, thnks for your help. USPS not showing my tracking info on there system either. Cant wait for my engine to get here!

HeatFire

BCKoots atleast you have an Axial 32 engine.. i'm stuck with my F4.1 for now.. sluggish engine..
4-6 days for it to come here? pffft 4-6 weeks if they dont get it mooooving soon
lets see who gets their engine first

vernier calipers?? easy to read.. never use anything else.. dont trust those digital once.. rather just use the good old vernier calipers :P

anyway.. internet got more guides about vernier calipers then needed.. so if you forget you can allways relearn..

anyone knows how many gallons the bearings can handle.. and sleeve and.. piston?

I agree as I all ways seal my engines when new to be on the safe side.
