Hi all,i want to buy a new engine and i have a complicated about 4 engines

1.Team Orion CRF
2.RB WS7T
3.OS VZB SPEED ALU HEAD
4.SIRIO KANAI EVO 4


I need to know how many gallons and how much time they hold the fuel.

OS Speed, Its very smooth, awesome millage and power. With the 5.5mm carb insert I was able to pull just over 13mins with a 16T bell. I would only use the OS Speed Pipe too, I have tried many others (JP3, JP4, RB pipes & Headers, AE FT Pipe & header, even some Dynamite pipes) nothing seem to do the trick. I also run the RC8 as well with the 120cc Xray tank. Hope I could help!

I would go with the CRF. The speed is an excellent mill but OS engines dont have the greatest longevity. So I wouldnt spend $500 on an engine that you may get only 6 gallons at most out of. I even know anexpierenced guy who only got 4.5 gallons out of 1, and parts are outrageously riced for the speed. I have seen the CRF in action and it is a fast mill, not shure on pipes or plugs for it though.

I'm going on 23 gallons on my speed. I've had three speeds and they have all lasted well over ten gallons. The speed clowns the CRF when it comes to power, usability, and runtime. You get what you pay for. there is a reason it is a world champion motor.

Your claim is redicoulous without rebuild...show me any engine that gets 23 gallons in stock form, with no rebuilds and I'll show you the Easter Bunny.

With that said, I see by your name you have some engine backround, so please share the secrets how you get 23 gallons of fuel through an engine

out of the 4 listed the speed is in a league of it's own.. I would look into the Mugen Ninja JX-B01. Identical power to the speed at a much cheaper price, and better reliability..
I run mine with a 8mm stack, P4 plug, and the 2060/2042 w/L header

I currently run the Sirio Kanai STI.. and have bout 7.5 gallons on it.. stock.. My previous motor Sirio BX STI, is still in my box as a backup with 7 gallons on it.. stock.. and love both.. still sticks on cold days.. very reliable, and rips on top end.. bottom is useable.. not rediculous like others.. I get 9 mins on a tank easy.. I only got the Kanai EVO III STI, cuz its the newest, and i wanted it..

The CRF, a friend of mine went from the Kanai STI, to the new CRF, and said its more powerful.. he also running orion pipe.. so.. i cant say..

I tried 2 Vspecs, and both of them lasted less than 5 gallons.. sure they were fast, but ran hot all the time.. when i mean hot.. i mean 250+ not hot.. but every other engine i ever ran never got that hot.. Awesome runtime on the tank.. but no longevity
