Boost and 100 Octane tune ought to fix any low end power delivery concerns. :)

Rowing 2nd/3rd seems like it would be awful.

...but I can't seem to drive a car in 3rd at all.

Im glad I ask this question.. Playing on my way to work this morning, I found that 3rd pulls pretty damm hard from 1500 rpms up,coming on hard around 3500. That may be because of the drastic difference in my tire dia. compared to yours Steve V.

Learning to do 2nd and then third sure is a lot cheeper than a rear gear!!! :lol: NOt to mention Harps theory of less wild ass torque thats there in 2nd.. 3rd may be my traction out of the turn ace. (JY, did you stay in 3rd all the way around Smokeys?)

once I went into 3rd.... I dont think Id go back to 2nd... well, unless somebody builds a damm pin cone turn. :pirate:

I'd probably bump the RPM's, if you can do it safely/easily.

...and you were wheeling that thing from what I could see Sunday. Kinda makes me want a CAM car.

I've had plenty that needed rowing between 2nd and 3rd. It sucks balls!! Every shift is a chance to screw it up and screw your time.

Only the kart is not much issue rowing gears since gear change is a toggle switch. Still a challenge to know what gear to slap it in

I don't know how you feel about the stock shifter John but I swapped mine out for a Barton. It got rid of a lot of slop and is a lot firmer and easier to feel what gear your going to. It's got a fairly stiff centering spring that lines it right up for the 3 shift.

I started in 2nd gear and stayed in 2nd cause my 2nd gear goes to 82, no need for 3rd but 3rd in my car does pull like a freight train.

I got it straight from Bartonshifters.com. They had just finished running a 10% off special but I sent him a message thru the forum and he took it off anyhow. Check mine out this weekend and see what you think.
