Hi guys, i've been running 13.5 blinky for a while now and wanting to make the step up to open class. But i'm not really sure how to do it in terms of motor progression. I have heard of some people progressively go down in motor turns (13.5 -> 8.5 -> 4.5) in order to slowly step up to 4.5t motors.

I want to ask if you guys think it is too much going straight from 13.5 to 4.5 motors + timing?

Why not try running your current motor with some turbo/boost and go from there?

13.5T boosted is pretty damn quick!

This is a good thread to read on the subject:

+1. I would also recommend 13.5t boosted as a stepping stone to full mod 4.5t.

I have recently stepped up myself
While 13.5 boosted is faster (used to run that too), the power curve is very different.
Your better off with a 5.5-6.5 and dial down your settings to start with

Damn good thread. Thanks for that.

What really help to have a smoother throttle fingers is run 2wd open mod or 4wd open buggy.

You could start with a 5.5T in blinky and add timing/boost as you get used to the power and eventually progress to 4.5T. If that's even necessary, depending on the size of track you're running.

What size track?

About 50m x 25m, 50m straight med grip asphalt

Most mod guys at my track run 4.5t motors, I've been reading some other threads and it seems like a good way to go is to start with a low turn motor and dumb it down until I can control the power rather than getting an 8.5 or something. But mostly practice practice practice I guess...

Skiddins

Get a 4.5 and run it in blinky.

P.S. The gap between 13.5 blinky and boosted isn't enough to make it worth it (yes, I've run both and run open Mod at nationals)

Will do. I have heard that running some boost instead of blinky can make the car easier to drive in the infield? Is there any merit to this?

I have also heard of people recommending new mod drivers to start off with turbo only and no boost though... So a little bit of conflicting recommendations there

Depending on the speedo you use, blinky profiles can sometimes have a more aggressive low-end compared to boosted profiles. Low-end grunt is typically where folks get caught out when starting to run mod, so the boosted profiles can sometimes make things a bit easier. I am currently struggling with the opposite of this right now, where I have made my motor setup too soft and I am losing time out of the corners

Anybody can floor it on the straight with a 4.5t or whatever you want to run. The hard part about mod, especially with a grip-limited class like sedan, is throttle modulation in slower corners. Taming the speedo so the low-end is smoother and you are more comfortable in the middle of the throttle can really help out.

I have never heard the recommendation to use turbo and no boost. I would just pay attention to whether a) the track is large enough to really need boost and b) whether your boost ramp is too aggressive, which could make the infield tricky.

a 5.0 with a small rotor might be a better option than a 4.5. it will have less bottom end. mod tc --- just run blinky until you're kickin' everyone's butt
