i would think you would get a few more mph out of it, like close to 40 mph, thats no joke for a truck this size either. You will be pretty close to that aftershock since its a big truck and not very quick off the line, my buddy has the mega baja and its really not that fast and we put an os .30 in it. I am sure you would be happy with those few mods, you can also put a little larger clutch bell, like an 18 tooth to get better top end too, you may loose a little low end but with those hop ups, you would be pretty good still off the line, its really a quick truck off the line. I have nice vented clutch bells also, just not on the site yet. If interested you can pm me thru rcu or you can email me
