Cool

Mr Aaron,
I have a O.S. .18TM and i moved up to 30% race fuel. I was told i might have to shim it and run a cold plug. My question is that the motor has a brass ring wich i thought was a gsk. Is this the gsk the shimm or both?
And is ther a web site to help find wich shimm to use for what application.
Thanks Mason

rltanner - Anytime

teambighead - I don't think the cars are an indication of mullet size. It matters more where you're from!

smitty - Haha.

racing mason - Those brass rings are head shims, which function as gaskets. You can add and subtract head shims (they come in different thicknesses) to adjust head clearance.

It is generally thought that going up in nitro content requires a taller head clearance and a colder plug, but that's not always the case. Many of today's big-block engines run better and more efficiently with hot plugs, and many engines perform very well on 30% and the stock head clearance.

Your best bet, is to talk to people who have run 30% in those engines. See what plug and deck height they've had the best luck with, and give that a shot.

Hi Aaron,

I have a Mugen MBX5 Prospect. What adjustments can I make to gain rear traction. My tail is all over the place, where everyone else is stuck to the track like glue. Please note that I have good tire tread (crimefighters) and the track is moist/watered. As far as the track dirt type, I am not for sure. Also, if I can get a little more steering with same or other adjustments, that would help too.

Thanks in advance!!!

Unfortunately, gaining rear traction usually means less steering. Having traction problems both front and rear is usually a sign that you're running the wrong tires, but Crime Fighters (of any compound) should be fine on any watered track.

Your best bet is probably to compare your setup to the fast guys at your local track (if they are running the same car) and see what they're doing differently.

Try these adjustments to get more traction:
- more rear droop
- lower rear ride height (unless you need forward bite, then try raising it)
- thinner rear swaybar
- longer rear camber link (move the inner camber link location to a lower and longer location)
- more rear toe-in
- more anti-squat

Make small adjustments at first and run them back to back so you can tell if it made a difference.

What about shock pistons and oil? Does this play any roll to rear traction?

Shock pistons, oil, and location will all have an effect on rear traction. But they're also much bigger changes and will affect the balance of the car more than the changes I listed. If you're mostly happy with how the car works, like jumping and navigating rough sections of the track, those should help with rear traction without totally changing out the car works.

You could make the shocks softer to slow the car down and find more traction. Try thicker oil (like 5 wt.) and a larger piston, like going to a 1.4 from a 1.3. And/or a one-step softer spring.

Cool. Like I said, talk to the fast guys at your local track with the same buggy and see what they have come up with.

Aaron, what kind of temp drop's are you getting with the b-mods cooling head's? They look awsome, and i'd like to get one for next season.

You might want to look at the diff oils too. Having the wrong oils can cause the rear too get way wild on hard throttle.Just another thing to confuse you Like Aaron said ask the locals, they're a ton of help!!

About 20-30 degrees, which is perfect. Any more than that, and you run the risk of the engine cooling down too much through the infield and loading up, which will make your motor run inconsistently. Besides, if your engine is still too hot, you're tuned too lean and not getting enough oil into the engine to lubricate all the moving parts anyway.

One of the best parts of the B-Mods heads, is the weight...or lack of. The engine head is one of the highest and heaviest parts of your buggy. A B-Mods head will lower your car's center of gravity as well as making it lighter. That's what O.S. was aiming for with the magnesium head, but engine heat doesn't transfer well from the aluminum case to the magnesium head.

Hahaha. It's funny that you're doing something to protect against going bald, by doing something that has been proven to make your hair fall out!

Yeah, but the hat catches them. So I can save them for a re-plant later! Hair club here I come!
