i will try to put something together i suppose

although mark is the one who loves to post thirty paragraph posts

Hi all. I've recently rebuilt an original P5 that I have and I've typically used a 9901 on it but was asked why am I running a bottom end pipe on an engine that has plenty of bottom which was a good question. I've ran this pipe cuz its suppose to give better run time and better suited for a buggy. Can anyone offer any insight on this and why not run a high speed pipe on this particular engine?

.

Gentlemen.

Would a Plus 4 Team p/s fit in a normal Plus 4 (the ones with turbo head) house/bearings? Are the crank different?

Get a second opinion, but:

-the crank is different- stroke is the same

I'd use a Team p/s in a regular plus -4. I have a regular plus-4 p/s in a +4C case

Hey, I made sure to say thanks......

I hear ya though, with that many possible combinations, it could get lengthy. Heck, if it's detailed enough, maybe we can get it put as a sticky so everyone will benefit.

All plus 4 parts are interchangeable with the exception of the heads

Thanks Monty. Allways a pleasure

Monty,

whats the rear bearing size for the BTT ?? i know the front is 7x19x6mm but not sure the rear. thanks

its a 14 x 25.8 x 6

I just picked up a R21 nitrotec engine and have read on other threads that people are stating that it takes a couple gallons for break in to be complete???Seems odd ?

I have always used the heat cycle method, any reason for me to deviate from this method on this engine???

thanks

I would break it in however works for you.The heat cycle method works fine.I have a little over a gallon on mine and its doing great.I'm getting 11-12 min a tank on an re10 pipe.

does anyone have a good pipe combo for a plus 28-7 in truggy? have a dynomite 053 in it now but not sure if I really like it. always struggling getting a good tune/performance on the low end with it.

your run time is based on the buggy?? or truggy??
