18hp duromax ez-go txt swap
I just did a full engine swap on my ez-go txt, I bought the mounting kit from VC and installed a 780 torque converter and removed both governors from engine and took the governor bracket off axle. I installed stage 1 on engine with heavy valve springs. I took it on a ride for the first time and it only goes 21mph, I thought it would go abt 25+. Why am I not going 25+ at 3800rpm? I have a 6” lift with 23” tires setup. Any suggestions?

Re: 18hp duromax ez-go txt swap
It struggles to get to 21mph at 3400rpm. If I push it to the pedal, it wants to go but want. It’s like my setup want let my engine get higher than stock rpm. I don’t get why! With both governors deleted it should be hitting 25+.

Make sure your belt has only 1" deflection . Too lose a belt results in a top speed loss. And of course the right width belt for your clutches.

I check my belt tension a lot bc I think that’s my problem but I adjust tighter and loser and nothing changes. It make no sense.

I don’t get it bc I have the same setup what redbeardsgarage did. He was doing 21mph on the road with over 200lb people. I just weight 125lbs and it’s lifted so it should go faster bc it’s lifted with 23” tires.

Re: 18hp duromax ez-go txt swap
I am running an 1 1/4 extra HD belt pretty tight and picked up a couple more mph. Also note I changed the VC supplied comet's weights to 68 gms. and the springs from the yellow to the green. Also my secondary on the yamaha is set on B 1. All these changes result in clutches that reach full speed at lower rpms.

Re: 18hp duromax ez-go txt swap
I am running a new 28degree secondary clutch. If I change the weights on the 780 comet clutch, do you think I will gain any speed?

Re: 18hp duromax ez-go txt swap
Yeah, something isn't right, I got 28mph on my older EZ-go and I was running the original engine, 22" tires a tighter belt for stronger low end, and just adjusted the rear-end governor and I still had more adjustment to boost it up a couple more mph... not sure the difference in rear-end gearing between the txt and the Marathon...

Re: 18hp duromax ez-go txt swap
Yeah that what I been sayin, I have watched and read so my forums and they go over 25+. I am running stock rear gearing of 12:1, it makes no sense why it struggles to go 21 at 3800rpm, when I hit the pedal to the ground it really doesn’t do anything. I want to figure this out. Could my governor be stuck in my axle?
