my conrod is not broke it has a lote of slop in it how can i fixe it

How will the p5xs preform with the Dynamite Platinum 053 Midrange pipe?
You mentioned the square header from OFNA with this pipe, is there a big difference over the header that comes with the Dynamite?

stock shimming for 21-4 running 30%?? How about plugs? Nova's? (so many to choose from, I get all messed up figuring them out)

huge difference when changing the header , it evens out the pipe and creates a balance . lots of punch and a nice pull all the way through the top , the medium round header makes the top end very flat .

the '09 p4's come shimmed at .80mm now perfect plugs, i usually use odonnell anymore odo77T/97T w/ turbo or odo77/99 w/ standard . i am going to use nova AGAIN this summer to see if everything got figured out ultra c5 standard the stock plug is good

do you think the square header from the OS T2050 pipe is similar to the ofna one you are referring to??

thanks for the shimming and plug info

that header would probably work pretty close to but that ofna square header or nova 41001 header are the best i have found . the 053 ofna pipeset works great

hahaha! I have that gonna pair to my N21 for my truggy!! but i think D8t is heavy what do you think do you accept trade in with a fair appraisal..lol plus 4/turbo/

on special occasions

you guys are awesome

i will try to help out as much as i possibly can over the internet

Houston, you need a website

i understand graves . the only problem is i dont want to get so big that i lose my personal touch by getting too many customers . i want to be able to know everybody by name and remember everything about their rc story . i have about 50 customers now and it is starting to get difficult starting

Whats the major difference with the Plus 4 vs. Jp B5 ???
can I get 10 mins out of the B5 ?
Which one will work better in Truggy ?

I also have access to a 421B probably needs to be freshened up pinched,bearings,etc.
Is that a smooth engine and how about mileage on it ????

sorry to have so many questions....

its all good

b5 or b5n ? p4 is a smooth 4 port , a b5 is a p5x in jp form 10 min. maybe but wouldn't rely on it to win 6.5mm restrictor at 250 w/ 9853 and 41001 or 41005 (square headers) and then you can rely on 10 min. . the p4 is a very smoooootthhh engine but still maintains a low end grunt that as most say feels electric motor like .

421b is a great powerhouse of an engine , 821b is the same porting but better block porting to maximize the port design . if the crank is good and the p/s still have some slight pinch it is worth it .

standard B5 its has the smaller bearing but has filled crank.... does it have more or less bottom than say a Plus 4 ?? I also have a p5x a guy at my local track hated it and gave it to me, besides bearing any major difference from P5 ? sleeves look exactly the same ... how do you feel about turbo buttons on both of those motors ??
