Default Best pipe for a .21 Sportwerks V2?

Just wandering if anyone had an opinion?
Thanks!

DYN 053 works well or even an 086

What kind of temps are you guys getting out of your .21 v2 motor. Mine is constantly around 260 degrees and the motor feels like it is still running rich. It is also blowing a ton of smoke. I am currently running an OS 2050 pipe and the smallest carb insert. I do like the motor but I get smoked in the acceleration department. I think this is probably due to it still running rich.

As for breakin I used the RB Mods method and the motor now has just over a gallon of fuel on it.

The only good news is that I do get 7.5 minutes a tank on my RC8. Ran a 15 minute main last night with only 1 pit stop.

You are restricting the hell out of that engine with the 2050. Try a JP-2 with the 6.5mm restrictor. It will breath better and make much more power. The temp will come down as well.
I'm getting right at 9.5 to 10 minutes. This engine also likes longer headers.
Being a 7 port, it will be smooth with a medium torque.
I love mine.

I've been wanting to try a different pipe. I just didn't know which way to go. I'll see what the local hobby shop has this week.

I was wandering, it came with a Dynamite 007HT on it and 9.0 restricter in it,
I will just have to run it first and see how it runs..

You will find that the engine/pipe will come on like a cannon that only shoots 20 ft.
It is good for nothing in racing. Interesting to drive though.

The JP-2 will wake her up and let her stretch out without blowing the tires off the car everytime you breath wrong.

What ever you do... Get your self three quality headers. Short, med and long.
These tune engines more than anything.

The V2 also likes the 7.5 restrictor.
Have fun...

How about the JP-1 pipe? Will it work very well?

Default Dynamite 21xp

Is this the same motor as the dynamite 21XP im going to start with a 053 and then if nothing will switch to a 086. This motor came with a shim and on some motors I heard to use it till motor is broken in. Also this motor has O rings everywhere is it still necessary to seal it?
Thanks guys for your time..

It is different than the XP, but most of the advise will apply. I like the 053 on it.

I've ran the Sportwerks .21 V2 in my Jammin buggy with a JP-2 pipe & 7.5 carb insert for almost 2- full seasons before I sold it with my Jammin buggy. I changed the piston/sleeve & con-rod at 10-gals & I had 11-1/2-gals on it when I sold it still running strong!

It always blew a lot of smoke no matter what pipe &/or carb insert I used/tried. With the JP-2 or JP-3, 7.5 carb insert I always get/got 8-1/2 to 9mins of run time, never anymore!

Right now I have a new Sportwerks .21 V2 in my Mugen Truggy with a JP-3 pipe & 7.5-carb insert, it has blistering top-end, midrange is OK, the bottom end is lacking just a little bit in the infield BUT it is very smooth all around. This past weekend myself & a couple of buddys tried to tune it for just a little bit more bottom end & we got it! Only thing is after 3-laps around the track the idle jumped up & temp too from 235* to 265* SO, we tried to lower the idle but notice when you back the idle screw out just a hair more then flush the engine starts to act like it has an air leak???? I remember thats the same way the idle screw was on my last Sportwerks that I ran for 11-1/2gals...

For the price ($175,00) I think this is a great engine for club racing &/or back-up but Sportwerks needs to put some more time into the carb as far as fine tuning! I wonder if the Dynamite 21XP Carb will fit??? They are the same base, no!?! I think for now I'll just drop the engine in my RC8 buggy, it should do well in there....

Both are SH made engines and all parts are interchangeable , a great combo is the 7 port piston and sleeve in the XP , more torque Great engines that last forever , more or less run with any engine out there.

Thanks easyryder! I'm going to see if I can find a Dynamite 21XP Carb to see what it dose..... Will the Dynamite .28 carb fit & work as well in the Sportwerks .21 V2?!?!?!
