hp? to pull 2nd gear

[henry rit]

I was wondering how much horse power it will take to pull my m in 2nd gear in 6000-7500# classes if its possible. I currently can pull 5000,5500# in 2nd gear the motor is working hard by the end of the track but I still spin out. I'm planning on redoing the motor this winter but not sure how far to go with it yet. was thinking about 4 1/4" bore with a 6" stroke, lp head, custom cam, pulling gov. , etc. would this combination be capable of what I'm shooting for. thanks

A lot of variables. Mainly, the track & your tires will dictate 2nd gear if you have the power. And just my 2 cents here...Example...if you have 16.9's SATS on a good track in 6500 let's say...you better have at least 90 - 100hp.

If you do what you say to engine you will get the HP. but than you have to be able to put the power to the track.

Like elkcagg says. But unlike he does...make sure you run near what the speed limit is, not at only half what it is! LOL. Right Greg????? LOL.

It takes 90-100 hp to win in NATPA Div two with 13.6es,18 inch hitch in 4500 !!!!!!!!! Just saying,some tracks bite hard,some say they pull on clay,but there are so many blends of clay around the country.

OK...I deserved that. Lol. For some stupid reason I had 3 mph locked in my head in that 4mph class. But I did alright anyhow. Got a 3rd place. Thanks Dale. It's all good. I had fun.
