Here is Cody running the Discovery at Rev, you be the judge

Temp depends how tight the engine is. If it's running well and smoke is puffing out of the pipe, any temp 280 and below is fine. 290+ is bad.. we generally run around 230 range depending on ambient temp it can get into the 250-260 range on a hot day. Colder day with an older engine, 200.. we run the 2013 pipe in Truggy with CK edition 5 port and 7.5 insert in the carb.

What pipe does cody like for buggy like my disco motors alot but 2013 is a little much in buggy i am running 2058 is what i am thinking

Big horsepower only matters on a straightaway. You might gain a couple of tenths or a few feet there, who cares? A smooth powerband, proper tuning, and a good clutch matter a lot more.

Given what you have observed, it could be that a more powerful motor is making up for the tuning inability or a bad clutch. A driver with a dynamite mach 2 sport/budget motor can put the smack down on a bunch of OS speeds, it has happened before.

track surface and layout can make a massive difference on the amount of power needed....We have a ultra high grip technical track and unless you have some serious HP you struggle like crazy to clear the obstacles.....I have seeen people's lap times go down substantially when they upped the power of their engine....But we actually have a track with more traction then hot asphalt

I totally agree, but your track is a somewhat rare case. I'm just trying to debunk the frequent myth that more hp means better results. No offense to your engine mod skills, I think you crank out some wicked products. I just feel that unless engine tune, clutch, overall car setup, and plain old driving are up to par, hp doesn't mean a whole lot.

Yup!..i agree with that

DO you know the diameter of the outer race??

its amazing how much different things are for us here in Canada.... we are always struggling for more bottom end....Our track surface is soo tacky that often times you cannot spin the tires even if you wanted to...In a truggy even my modified Bonito can't break traction from a dead stop... And without the ability to spool up the tires many engines just do not have enough grunt to clear the obstacles..... Most of the stock engines just feel dead and gutless and do hurt laptimes, especially in truggy....... On high bite a Truggy requires a pile more HP then a Buggy does...of course on a loose surface it doesn't make as much difference........tho I will also say the persons skill in setting up the suspension will also play a big role in how much power they can put to the ground.. a properly setup car has a pile more traction to work with then a poorly setup car......

Hey PK. So I run my engine all seems well. It rips and rips but when I stop and let it idle for a few seconds it will then load up and fall on its face when I take off. Obviously this seems to be a LSN issue but my only concern is I'm constantly leaning out the bottom and it continues.

How new is your engine? It can take a 1.5 gallons to fully break-in.. What is your Idle gap set at? Set it for .5mm - .7mm then set your LSN. Warm engine fully, adjust topend, then readjust LSN if needed.

I have close to a gallon ran through it. Not sure on idle gap I never measure it.

It's kinda tough to figure out engine tuning stuff on the forums. Are you going to Toys 4 Tots this weekend? I can look at it there if you're going.

Yes we might go. The only thing is the weather is looking kinda nasty so we're not sure.

brisk and cool for Palm Desert, but should be a beautiful day.. I imagine it will get up to 70 degrees next to the hill. Hopefully see you there..
