Fact is, for me anyway and i just do not care what you guys says. Red putty in the crank works like a charm!!! I do not care shit whats the theory is behind it, it works. And it works even if the crank is not drilled and lightened. It is an advantage that it is drilled but it is not amandetory.

If you can not see this on a dyno, well, then the dyno is just not good enough!

I have a black ATV slicone. Will this work? Or is the red one better?
What are the one of the putty coming off? If it does, its end of the engine?

I have been experimenting with this quite a bit and all I can say is that it does make a significant difference.
I noticed that after the mod the engines spools up quicker. Making the engines accelleration faster. I believe that when you add the silicone you flow the crank and you decrease the crank volume. In doing this the pump pressure is increased and this in turn gives rise to faster acceleration.

I found that with this mod it does take away alot of bottom end control. On loose tracks you tend to loose traction easy. This mod will definitely benifit on-road engines more.

Today was the first time I read this entire thread and I think it's really funny. Almost sounds like someone trying to convince people that they saw a UFO, the Lochness monster or Bigfoot.

Nice.

I was going to try this (without the drilling) until I started reading some of the latter posts. I'm not sure what to make of it now. It made perfect sense to me before, but having mxwrench post that he doesn't see any difference on the dyno is making me think twice about it.

mxwrench knows a thing or two... So i would take his advice as he has made ALOT more dyno runs on the X-Dyno then all of us.

I've had motors that showed an increase in performance by adding material to the crank inlet area and some that you couldn't tell the difference, but I don't think (or at least what I want to believe ) that I've ever hurt a motor by doing this, (unless we want to talk about the one I siliconed on a Friday night broke in Saturday night and tried to run Sunday - boy undried silicone will mess up a motor!!!)

the dyno is giving you a plot of rpm/hp. It is not showing how much fuel is flowing to accomplish said HP, nor is is showing throttle response based on letting off alittle then nailing it for a corner.


I think you guys are both correct

It may not increase max hp or rpm but it could increase throttle response and/or fuel consumption.


I do know, neither JP nor Grinder would add something worthless to your engine, measurable or not


This thread is awesome, love modding discussion. I have sooo much to learn.

So you mean to say maybe it's similar to a carb restrictor?? (just thinking as I'm not really sure). It won't really mess with the max RPM or HP but makes the motor act differently coming out of the corner due to different spool up?? If that is the case, then the putty can be an advantage.

How much of a "per lap" performance gain have you seen once you've added a ramp?

It would be interesting to discuss the theory on what exactly is going on in the engine to impact throttle response. I don't know how or if throttle response can be inferred by the dyno results.

True

From a manufacturing standpoint, this seems easy and inexpensive enough to do, so why doesn't every engine come with a ramp?
