I'm looking for a new engine. I narrowed it down to 3 engines. They have to be Efra legal.
- Sirio Evo 3
- JP FX T03 full option
- RB V12 Efra rody tuned

The JP and the RB or almost the same in pricce. The Sirio is cheaper.
How do they perfom againt each other?

the jp and the rody are the same as far as im concearned,i cant really feel the difference in the performance.,as far as the sirio goes i would go with the jp or rb over that anyday of the week,all the sirio engines i have ever had were somewhat difficult to tune,seemed like i always had to tweak it even more just after i thought i had the mix.my jp and rb mills arent like that.
if you have the $$ go jp,you wont regret it.

the jp and rb engines are fast and reliable but the Murnan Evo 3 is the fastest legal .12 i have seen. a good friend of mine picked one up and it has crazy power. it kept a good tune and ran cool.

This is a very easy Question to answer! Go with the JP, The Jp reputation speaks for it's self!" There is no equal"

If you would say the JP is a 100% engine. At how much would you classify the Sirio?

wendellc1

Sirio EVO3, 85% for performance, 95% for the price and 40% for reliability. Over half of the people that ran the Sirio 3 broke their cranks.

You should also consider the Palmaris PR12. www.palmarisracing.com. They also have a tread on the engines only forum.

Is the cranck still a problem for the sirio evo 3? I thought this was a problem with the evo 2 and the evo 3 has a whole new cranck.

It is completely new. As far as I know, there are no problems with the crank of the EVO3. I race with it and I am very satisfied with the reliability. After 5 races (12litres 16%), only the rear bearing was a little wear. The conrod and the pin were like new. However, I rebuilded the engine just for psychological purposes. I changed the two bearings, the conrod and the pin. I would also say that the rebuild cost was rather low. The power of the engine in the track, compared with all the other engines, is absolutely comparable. You can not say that EVO3 is weaker than the rest of the engines. I would say that it belongs to the most powerfull engines.

I just finished running the SIRIO EVO 3 at the Aussie nationals and the engine is at least as quick if not quicker than the quickest and latest around.
Infact I was in the same qualifiers as the winner (LRP) and was backing off at the end of the straight as courtesy to him so as i would not clean him up.
And balls out of the corner, lots of them.
The early cranks there were some failures but the latest ones are flawless.

Hi,
What fuel are you using for the EVO3?

Thybaut

Is the engine easy tunable, I read in other forum's that it was a bitch to tune.

I'm planning to get this engine end this month.

Thanks

has anybody tried nova tuned version?

etgdpu

I am not an expert in engine tuning but I have never had any problem with the EVO3.

But you will be running the I version and not the E version right?
