I was thinking about upgrading my stock TPI intake to either a holley stealth ram or an lt1 intake .For 2 reasons one too make more power obviously.

And two is the one i'm asking about.I'm trying to save the stock 150,000 mile rear end, for as long as possible and since the Tpi intake is such a low end torque monster,Would the change to an HSR or LT1 intake be less hurtfull to the rear end since they would move the power band up and reduce the amount of low end torque.

Any replies will be appreciated.

 

When you are trying to save it right now and you are concerned about it, chances are it will break. Yo said yourself that you are wanting to make more power, that can break a rear end, especially a 10 bolt. Go to a junkyard and dig out a 9 or 12 bolt and slap some gears in it and call it a day. Or dig out a 10 bolt and put a couple $100 into it. The 10 bolt can take punishment, but only so much. Many people on here running LS1's and fast traditional sbc's naturally aspirated are reporting breaking them.

 

The HSR makes more HP with some loss of torque, but I still tore up a b/w 9 bolt with it at a drag strip. If you are going to make more power you will need a rear end that will handle it. I would recomend the HSR over the LT1. I know guys who gained nothing with the LT1 on the L98.

 

Did you have drag slicks, street slicks or street tires on the car?

 

Street tires, the ones in my sig. I had the pressure down to 16 psi
