I been thinking about how to get more HP and TQ....I tow a 8000 lb camper 6 or 8 times a year. Most of the time it's alright except the long mountains following my buddies with there desiels . My truck has 90,000 would it need rebuilt first and what is a good supercharger kit I could get,,since it would be cheaper that a new truck,,,thanks

 

At 90000 I think it would be a good Idea to have a basic rebuild done if your not going to run high boost levels. If your going to run high boost levels ,forged internals is a must.

 

go for a roots type or waste gated centrufigal, NOT a twin screw

 

Ok,,Thanks alot,,,I probably need the cam phaser job also,,you think ?

 

I Have a whipple on my truck with 4.88 gears, and air bags. The thing tows like a beast! my boat is about 8,000lbs when loaded with gear . I run 75-80 at 1/4 throttle. I havent towed through the mountains yet, Next June we are headed to Lake Powell so i will put it to the test then.......

The tune that whipple uses is horrible i would sugest getting a custom tune if you go that route.

 

Did you do a rebuild WhippleScrew ?

 

I say no. 7 to 8 year old truck , save the money

what rear gears do you have? going to a 4.10 would help. look at tow ratings and changing the rear gears get the biggest results.

had a centrifugal and at 2500 to 3000 rpm it did nothing, towed a 5000 pound trailer and i could not really see a difference.


to me a boat pulls different than a TT, the TT has the aero dynamics of a brick , the boat cuts the air so much better.

if you did rebuild the motor, you have to know the trans is right behind it. figure in a rebuilt trans, rebuilt motor, cost of SC and cost of installation and tune, you end up with a 8 year old truck that you put over 10k in that is still an 8 year old truck. at 7 to 8 years old realistically small things are going to start going wrong.

seriously work up a budget as to what it will all cost. if you have 10k to 12k cash and love the truck then that is up to you.

 

I'd be a bit more worried about the cooling system and trans temp. Pulling high into the mountains will create a ton of heat. I know when I pull anything with a good amount of weight to 7K feet the truck gets really hot.

 

Greatly put,,,I'll keep it stock for now,,,Going up N.C. mts..Trans temp got to around 225 on my scan gauge for about 10 mins.

 

my trans runs cooler on the highway once I added boost as it maintained OD on all the hills
