I ran the Mephisto during practice for the GLC and then all the club races after. I also ran the ISON previous years on the same track. The ISON gave me tremendous mileage and a lot of torque around that layout. I ran my all time best runs on that layout with the ISON in 2015. The Mephisto uses slightly more fuel, but has a little more torque than the ISON. I am currently burning the wheels off the car with it. Been working on clutch setups to reduce tire wear. Been close to holding my own against the GSR2.7 which is a derivative of the OS 2103. Used the medium header on the Mephisto and the short header on the ISON. Used 2015 pipe and Byron's 25%WC fuel on all three engines mentioned here. Hope that helps.

Thank you for the insight. much appreciated.

Guess ill run the ISON a bit more until next year perhaps.

has it been released and any test result about this engine?

how many nitro and oil percentage u guys now running, with stock head shim.

Does anyone have any info about the new mephisto .12 from Novarossi?

Yes.

The new .12 will be a mephisto?

I think yes.
Because there's already 21 off-on Mephisto.

Hello guys,

Bought 2 .brand new 21 Flashes for € 358 including shipping ( $ 314,-). A couple of simple questions for the experienced expert:
* Does the 07009 (R7) conrod fit? It now has the 07006 (R4). I'm pretty sure it does but just checking
* I have to measure up the timings on the crank and ports yet and will post it overhere but does anybody have some values for me upfront? ie: crank timing mod? For example oepning @ 32 after BDC and closing @ 71 after TDC.
* Any other tips? I see the main bearing is an 11 ball ceramic standard 14.5 x 26 x 6 bearing which you can buy anywhere for little. My personal favour is Freerun on Alieexpress

You can also clearly see the booster port fanges in the sleeve which the ISON for instance doesn't have...

thx in advance

1) I told you last Sunday
2) I hinted it on yout 1/8 FB post about a simulair engine, although I expect that this is a same engine in timings.
3) Hmmmmm.....

Yes you did

Hello!

Does anybody know the difference between the usual Mito Wc and the Limited Edition?
It is written on the cooling head of it also.

Many thanks in advance!

I'm using Mito 12 WC with Hipex 2669 pipe and medium (30mm) manifold. Is there any sense to switch to Novarossi pipe 2660 and 41616 manifold?
