When he is 18 years old,I will give him my Impreza CG8 for practice. Have you seen that cartoon Initial D?

noobatron

ahhahah better start early then!!! and get him to deliver tofu or STS parts early in the morning ahhahah

I have some STS engines for awhile and finally taken measurement of their porting. I modified the exhaust port and intake timing on my engines for experiment. The result is better top end but slightly less punch. Good for smooth and large track. I just want to share the data to STS fans. Ok. here they are.

STS RS3
Schnuerle: 112 degree
Boost: 108 degree
Exhaust: 162 degree (mod.)
Induction(stock): 207 deg. (30 ABDC - 57 ATDC)
Induction(mod.): 212 deg. (30 ABDC - 62 ATDC)

STS D5
Schnuerle: 118 degree
Boost: 116 degree
Exhaust: 162 degree (mod.)
Induction(stock): 204 deg. (30 ABDC - 54 ATDC)
Induction(mod.): 212 deg. (30 ABDC - 62 ATDC)

I will take the measurement of my D3 next time.

I got the following data from rc magazine

Collari .12
Schnuerle: 114 degree
Boost: 114 degree
Exhaust: 159 degree
Induction: 213 degree (32 ABDC - 65 ATDC)

It looks like the induction of STS opens 2 degree sooner than Collari .12

By the way, if the crankshaft is lightened, say 1 or 2 gram, the engine will have quick acceleration from low rpm to high rpm. But the idle might not be as stable as stock one. Just need to tune the bottom and idle needles again, and it will be fine. Not sure if it is legal for ROAR to lighten the crankshaft....

Great info Wang, but could you tell us what was original exhaust degrees before moding???

Ref. crank, yes you can lighten it, ROAR rules have no restriction over moding cranks, they are similar to IFMAR rules....but wacht out for balance.

Hello afm,

I'm sorry, I did not have the chance to measure the stock exhaust port. I got the compass after I did the mod to my engines.

Thanks for the info on crankshaft.

Just a little piccy to showing my new thing for today.

to the best of my knowlege this statement is not true.

Our parts will retrofit into the sts line as they are produced for us by sts. They are a little different in some places but will all retrofit. We are changing a few things in our lines after we get them but I won't say what.

PS all front bearings leak somewhat. All Of them!! Novas too. If it leaks bad the low end is probably way to rich. The bearings are japanese 607Z type the same as most of the manufacturers are using. Their not cheap bearings by any means. There are also alot of bearing seal failures due to the fact that people are using the big centax shims between the collet and bearing. Those tend to warp inward and make the seal spin in the outer bearing bore killing it.

Thank you Dennis
