i hoped 4 more power its fast but no wheelies
ne tips it runs on 30%

Foxy

what gearing?

HerrSavage

Mine wheelies almost too much with 18/47 and front ext TVP's... I was unintentionally wheelying at like 1/2 throttle on the first break-in tanks...

lauderboy

17/52 i think

Foxy

Maybe you just need to tune it.

lauderboy

i have its tuned sweet but still no wheelies
my k4.6 with the same gearing was very good

if anything the Axial has MORE power than the K4.6. they're very similar engines.

does it run funny? any stuttering at WOT or anything like that? does it idle high? sounds like it isn't tuned right to me.

Something is not right with your setup. Your truck should be popping wheelies all the time, regardless if at a stop or already rolling. What clutch are you using? If you are using plastic or carbon shoes, dump them and get aluminum ones. What gearing? 17/47 is a good place to start. How tight or loose is your slipper? Keep it on the tight side-mine is as tight as I can get it. Too loose and it'll just slip all that Axial power away, not to mention destroy the slipper pad.[8D]

Oh yeah, make sure your carb is opening up all the way at WOT. If not, that will kill power big time-adjust the linkage until you get the carb's slider all the way open.[8D]

just finished breaking mine in and it wheelies like nothing and i still have to lean it out some more. I dont want to gun it too much yet. but i still gun it more than i should. my setup is an X SS

The Axial .28ci and K4.6cc are just about identical engines down to the timing profiles. The only differences betwen the Axial .28ci and the K4.6cc is the Axial engines have the leading edge of the crankshaft cut with a scoop and the crank shaft 14mm diameter has 2 oil grooves instead of the K4.6's one oil groove. The Axial engines also have carb ventri inserts (I think) so you can choose between 8mm, 8.5mm, and 9mm (I cannot remember if these diameteres are correct). Also, the Axial engines use 2piece head button and heatsinmk and you can use tubo plugs with Axials where you cannot with the K4.6

Aside from what I just mentioned above, the cooling fin pattern on the block, and the color of the heatsink, they are identical engines.

1st it's tuned fine
2nd the spur is tight
3rd 52/17 combo this was fine with my k .46
4th 30% nitro
so it must be the poor clutch pads so i will need so tips for a good alloy setup thats going to fit my flywheel or is that not a problem

thanks for the help guys it's ALL GOOD

try 17/49 gearing. Also a nice aftermarket pipe will help. Nova aluminum clutches will fit also mugen makes some good ones.

The Axial .28 overpowers and outperforms the K4.6 by a wide margin, so all of these "little" differences add up to make the Axial a better engine. Also, calling them the same engine isn't really fair to the Axial, nor is it technically correct. To me, it's like calling the LS1 and LS6 or the LS2 and the LS7 the same engines. Aside from being "small block Chevys" and having similar appearances, they are not the same engines in and of themselves. The differences between all of them distinguish them as their own and thus the same principle should be applied to the K4.6 and Axial. That's my stance on it and others should consider that as well so as not to mislead people.[&:]

You have to buy the optional turbo head button from Axial to run turbo plugs. You can't run a turbo plug with the head button the Axial comes with. Another overlooked difference, and quite significant in my opinion, is that the K4.6 exhaust port is "oval" on the inside of the block casting and round on the outside-it's necked down and likely a restriction. The Axial is round the whole way through and there is no change in port size.[8D]

No kidding. Mine was popping wheelies during break-in too when it was still quite rich. Now that it's broken in and leaned out, it wheelies all the time-I'm probably going to tune it to kill the wheelies and/or go with a 18 or 19 CB.

There's no need to go with a 49t spur. A 47t is plenty.[8D]

lauderboy

is the ofna alloy clutch anygood

My Feedback: (3)

No, run mugen or STS shoes

tmdz28

i like the way you are thinking my good friend [8D]

Vigilante212

The ofna clutch shoes wear out fast. I have the blue ones and I think about 1/8" of them is gone
