i'm looking to buy a new .21 buggy engine.
have tried novarossi P5 based engines and the OS Vspec, looking to try out other brands.

currently in mind these 3 engines...
Sirio s21BX STI (with the blue head)
Werks Racing 21 7ports Team Line
Picco P7R evo

any comments on the above engines?
anyone using them, appreciate your feedback.
thanks in advance!

Get the Werks. The other two will cost enough more that you could get the Werks and a JP2 pipe for the cost of just one of those engines. Ther werks will run with or past any offroad engine on the market and get 9+ minutes a tank doing it.

JP Racing FX21 B5NS, JP 2 Pipe, Werks medium conical header and you have one ripping engine! I can't complain about my JP. It has excellent mileage, holds a tune very very well and runs awesome. I got many remarks about how well it runs on the track. Then again, my RG does all of the above, but is not putting out nowhere near the power the JP puts out. You have to remember, the engine only runs as good as you make it!

With this type of question, you can ask 10 different people and you will get 15 different answers. There are many high quality engines made by Novarossi, JP(is Novarossi based), RB, Werks, OS, etc. Anything Italian made is very good.

thanks for the reply guys!

juz curious, is the werks teamline pretty much the same as the older werks collari b7?
other than using a different head, are there any mods done to the engine?
i know that using the term 'teamline' might just be a gimmick, much like the team orion wasp .21 team edition which was basically a P7-R.
i did consider the wasp but a blue head is cooler looking than a silver one, not to mention that the wasp was abt $30~40 more than the picco.
correct me if i'm wrong, but they're the same engine right?
and is it true that the picco's piston/liner cost a bomb?

let's say that the 3 engines mentioned cost the same, which one wld you get?

no one's using the sirio STI?
cos i can get it pretty much arnd the same price as the others...

or shld i wait for the OSspeed V-Spec?

questions, questions and more questions...

The Werks "Team line" B7 is not the same as the standard B7. The newer engine is tuned for a little more bottom and a smoother power band and yeilds a little better fuel milage.

If those three engines were the same cost it would be the B7 hands down and even if they wern't I would still pick the B7.

IMO the Werks does not belong in that group.

Othere engines that would, would be the RB and the Nova.

Just my opinion!

OS V-spec with a t-2050 pipe. Why bother with anything else? Holds a tune, has power everywhere and is a proven winner over and over.

guess the Werks Team Line B7 is highly recommended.
quote from Werks site:
'The B7 is an excellent choice for larger circuits where horsepower and RPM is critical.'
does that mean the TL B7 is lacking in bottom end?

i've always preferred lots of bottom end (read P5 based engines), with a smooth transition to the top end.
not many engines are able to do this, mostly modified ones i guess.
(still my all time fav is the Novamax M5T MF )

that's why i was looking at the sirio BX21 sti. seen the kanai sti version and it hauls a$$. didn't like the green head tho...

correct me if i'm wrong, but the Werks TL B7 is made by sirio rite?

so far choice of engine...
1. Werks TL B7
2. Sirio BX21 STI

ruled out the picco, not too much rave reviews on it.
still waiting for comments on the sirio...

i am just giving you an honest opinion of the engines i have ran, i had a hot mod rossi p5x and a GO 5port race, i also had a hyper .21 8port (first engine) i like you feel that on the tracks i run on a 7port is too much top end and not enough bottom, One thing that is very important if you race is you need an engine that is fast and will go 7 1/2 min. between pit stops without a problem, if you can't go that time forget about doing good in a 20min race or longer. i can tell you that i would choose the Go 5port race over my hot modded p5x any day of the week even if it cost more. As far as i am concerened the power band on the Go engine is perfect and it is as fast as the more expensive mills, it has also shown to last more gallons than the other taiwan made engines. Fastest buggy down the straightaway is not what wins races its fastest from corner to corner, which means you need strong bottom end. Currently you can get the Go Tech engines from www.racefactorindustries.com, but you can ask your local hobby shop to carry them as well.

rdeppen,
i'm currently running the V-Spec with d T-2060 pipe.
change to novarossi bearings and had no prob with it. the powerband suits my driving style very much.
just thought of trying out a new engine for the new season.
maybe i shld wait for the OSspeed version?

rocket42,
thanks for the recommendation on the Go-Tech engines,
will check them out!

Haven't looked at what the other motors are your looking at price wise but I know the V-specs have come down in price as the next GEN OS motor is around the corner. I've seen them as cheap as $269.00. That's money well spent for the caliber of motor the OS is.

I always ran Nova based motors in the past, Top, Rex and so on. My all time favorite was the P5 Nova motors. If I couldn't get an OS I would run a P5x. Tried Picco's hated trying to get a consistent tune and the clutch setups they required. Ran a few RB's solid performance but never had the bottom end I liked no matter what pipe I tried and everyone of them seemed soft on the bottom and needed clutch work to go great on a tight track.

This is the first time I've run OS .21's always used there .12's and 18's in the past in 1/10th truck, On-Road and my Revo. I can't say enough good things about my V-spec though. I have just over 2 gallons on it and if I get a full 3rd gallon out it I'll be happy and toss it in the trash as I bolt in a fresh one. I've had no bearing problems with mine that I heard reported and the power is just amazing.
