Hey Supertib..Still waiting for the above reply. Thanks
ORIGINAL: joydude630
Are the ofna pipes compatible with the OS Vspec or Speed?
ORIGINAL: supertib
053 or 086...both will make more power then the EFRA pipes.......
ORIGINAL: joydude630
086 is the tuned pipe you recommend for the GRP .21. What role does the pipe play for the GRP .21? Is it just the sound you are emphasizing on? Does it play any role in terms of top-mid- low end of the engine?

Also I am not knocking GRP engines by saying they are identical to the Ninja engines.... I love these engines and have modified many of them with exceptional results... These are high quality motors with amazing fit and finish.... I find the powerbands to be very smooth and linear and mileage to be excellent.....I would recomend them to anyone !

053 works decently..the 086 not so much...MSR 1005 works killer and so does a JP3.... and of course you know the 2060 is also well thought of on this motor.

Nothing mild about this engine. So far it has kept up with or passed any other engine on the track. So far it has been a screamer with great power.

the Dynamite pipe and OFNA pipe are nothing alike..the OFNA pipe is louder ( much much louder) and to me makes more HP....
ORIGINAL: jonnymac
The dynamite 086 and OFNA 086 (or Novarossi or any other 086) are all the same design. Same with the 053'3 063's etc.
The quality of construction and materials may differ though

just becaue they are noisier and give different power output doesn't mean they are not the same design.
hardcoating can provide more noise and different power profiles as the resonance is different. Do a search on OFNA headers and you will see some of the power issues with them and the fixes

Choose the OFNA pipe over the dynamite...its louder and makes more power...most likely they have the internal baffles drilled differently as the OFNA pipe is much much louder

The Dynamite 086 is hard coated and has a different header, but the design is the same. OFNA headers can be notorious for not being aligned and restrictive. The dimensions of the pipe however are the same. which is what i said in my post.

If I need to run 30% fuel on the GRP; do I need to add or remove shims?

you should see what a strong 21 looks like !!!! Many motors I consider strong cannnot be used in a Buggy, as they just have way too much power.....
As I say guys, a GRP Is a smooth easy to drive .21..it is not by any means the fastest or most powerful race .21... but it is one of my favorite engines

I got the promo kit and it came with no manual. That's disappointing. Does anyone know if I can download it somewhere?

Example I would say is a Picco .21 Evo2. As you once told me earlier it was always recommended in a truggy.

Yes a PIcco P7R or Jammin JPX will both out power and outrev the GRP engine......

Is the OS P3 a good glow plug for the GRP .21?
