Hi, I have a 2000 first generation tahoe limited 5.7 at this time i have full exhaust, K&N intake, super chips programmer - "it's worth the $" power slot brakes It will do over 135 MPH. my goal is to run and film the gumball rally. most or these cars run 150 to 200 mph does anyone think that an old HO can do it with a LS7 and low stiff suspension? I know somone that has run a Benetly GT that car has a twin turbo V12 550 HP and it will run 180-200MPH and it is 800Lbs more than my HOE.
Thank's Shawn

 

Tahoes are slow, there's just no way around it.

 

Why would you ever want to take a tahoe to 180mph?? You might as well be trailering a casket behind yourself. Your suburban weighs 5123 pounds stock and and a Bentley GT is 5258 which is not 800 more pounds.

 

Anything is possible if you want to spend the money...and weight isn't the biggest issue with your hoe anyways.
You'll need much more than your set-up to get there. Figure a turbo charger with more than 650 rwhp. Anyways, at those speeds what's more important isn't weight but aerodynamics...weight is more important when considering how fast you want to get up to speed, otherwise stated as acceleration.
The fact that our trucks are bricks is your biggest issue and at those speeds will be your truck falling apart, 180mph is gonna start rattling your truck apart, issue isn't so much suspension or power, which you can easily achieve.

 

haha the "hoe" world speed record shootout 07! I ran a yukon with the same everything I had, same size wheels, motor, everything! I have escalade gauges and it went past 120 but I dont know what it really did but all I know is I aint doin it again lol little creepy so 180 is a negitive for me agh haha!

 

i have toped my tahoe out with my 5.3 and a kb super charger it dont feel to safe 6000 rpm and burried speedo my tuner tuned my truck up to 200mph but with 373 gears you will not get there. now i got a 6.0 with a cam springs push rods full exhaust pinned crank 9 lbs of boost kateck connecting rod bolts double roller chain ls6 oil pump and will be turning up the rpm to 6500 and now have an aeroforce gauge to read my mph when i get it tuned next week i will let you know how fast you can go unless the cops let me know how fast i was going and send me to jail im from Canada up here they just passed a law if your caught doing 50km over the impound car and suspened you lic on the spot. cant wait for the good whether to hit the track with the 6.0 ,14.7 best time with 5.3 looking for low 13s now
