Murnan MR-12 Crank

cybertoolzz

excellent work - i'm impressed. can u show the BEFORE pics?

u widened and polished the carb opening? u didn't open the carb inlet right - that's still 5.5mm - correct?
i'm no expert but what does a wider throat do other than allow more AIR?
and even if u open the throat by 1-2mm that is only a VERY SLIGHT increase in the air volumn entering the cab. i fail to see any SIGNIFICANT improvement here... (but again i'm not very l33t)

now the crank - again excellent stuff - very sharp and polished work- u shaped the scoop up into the bore and it looks like u beveled the scoop back INTO the bore opening slightly.
how far can u push this technique - can u take it back FURTHER into the bore opening?
what about the INLET PORT of the crank? did u do any work back there? widen the port - flare the sides, etc? can u post a pic?


what about sleeve work - that seems to be where most ppl get creative....

(i wanna be l33t 2!)

These things are great! I have a Murnan modded NovaMega MT12 and it has more power all the way through the rev range, and increased top end. I didn't know how much better it was till I got a really good exhaust system (NTC3), now that I have, this baby will scream...I've been running it hard since Feb. and its still gets stronger as it gets more wear.

Drive one or chase one, Uriah's got the HEAT!

grinder/murnan - chk out the discussion on the RB X12 Rody - how much would it cost to modify a STS RS5 like the mods used on the RB Rody? would it be worth it?

Hey Grinder

Do you do MT 12 Turbo's. I'm looking for an all out 12 Turbo to run in my GT4R. I'm going to be running against 835's(Serpent) with all out 15's.

If you do what's the price for Modding with motor. I'm looking at Carlsen's, but there harder to get here.


Thanks!!!
