| Have a 95 Caprice with a LT-1 that had a rod knock. So I got a LT-1 from a 95 Roadmaster Wagion with 36,000 miles that was a old man 73 years young driver. He was backing up and took out 4 cars ,so his kids made him sell it. This is what I did to it
Stock intake ported (gasket match the throtal body to 54mm) Ported throtal body to 54mm Hooker super comp headers jet coated MSD coil Arazona marien and speed cold air intake MEZIER race type water pump 95 SS Impala twin fans 2 1/2 inch exhaust (Heartrthrob Exhaust ) mandral bent Knock off flowmasters PMT FABRICATION 91-96 B BODY EXTENDED REAR TRAILING ARMS 22" Zink rims
This car is a dog to me and I see other people take off the air pump and the bypass line that goes in the throtal body and I have not done that. What can I do to give this car some power and do not want to do a cam change. Please tell me and I will try it . Thanks eveyone
95 SS Impala 67 SS 427 Chevelle BMW M3 drop top BMW 850 5 speed V12 41 Willys coupe | |

| Get rid of the 22's and put a normal size wheel/tire combo on it. Then it will accelerate and stop noticeably better.
But while you have the motor out, why not swap in a cam and get a converter? | |

| The LT-1 is in it and has been for a year now . The rims is not what is killing the power the my 95 SS Impale has 26" and it runs 14.583 with the same 2 1/2 exhaust and throtal body and Hooker super comp headers and ran air kit and 4.10. Will the air pump and the bypas on the throtal body make a big deal. ? Going to SD consepts for a dyno tune on the 3ed but that is like $600 and thats killing me . Thanks everyone | |

| that car would run easily a second faster with 17s on it... | |

| The air pump and TB bypass will provide negligible gains, if any. Those just clean up the engine bay. A lot. As far as the 22's and 26's... If you must run silly tires, you'll need gears. 4.10's at least. Save your money on the dyno tune. You won't pick up enough power to justify that cost with the amount of mods you have. Your car is still pretty stock... | |

| as for tires, the car is designed to run a tire that is 27.4" in diameter if you're running 22s, your doubling the weight of the wheel and odds are, you've also increased the wheel diameter
if you've got 26s on a car, and if a 255/20/26 existed (I dunno about tires) you'd still be at 30" in diameter for the tire
if you want to go faster, get smaller wheels.
if you're running a stock rear end, bigger diameter tires are like going even bigger on gears. | |

| Yep, people don't like to hear it but there really is no need for wheels above 18" or so, just to clear brake parts really...anything bigger just increases unsprung weight, wears brakes, etc.! | |

| plus if you want to go fast with big ass rims like that you need bigger brakes. | |

Matt has it right. Just remember, you could have two tire/wheel combos that are both 30" in rolling diameter. If one set had 15" multi-piece, lightweight spun aluminum competition wheels mounted with lightweight racing tires, -and the other had 26" cast Chinese, mystery alloy, "trophy metal" and were sculpted into a garish, ostentatious shape -that "lookt-did" like a GIANT inner-city "project-gurl's ear-ring", then you might expect there to be a "SLIGHT" difference in ROTATIONAL INERTIA! Truth is, the two wheels with the same rolling diameter AND overall unsprung weight could have very different rotational inertia, if that same weight was stored at a much greater distance from the axis of rotation. It takes a LOT more HP to accelerate a given mass from motionless up to "X" RPMs, IF the concentration of that mass is carried at a great distance from the axis of rotation, common sense when you look at it this way. You must also take into consideration the "X-4 factor", that you are simultaneously attempting to change the rotational "speed" of ALL FOUR WHEELS! The MOST important key to making more horse-power is in the choice of heads and cam. All other modifications are helpful, but simply in facilitating whatever potential is possible from the heads & cam. Of course you will need to provide the appropriate compression, octane, timing, exhaust breathing, header tubing length and diameter, intake runner design, combustion chamber shape, cubic inch displacement, rod/stroke ratio, etc., etc.. But, without a GOOD choice of heads & cam, you are providing assistance to what? | |

| I know the 22" and 24" do not help the going faster but Ill never drop the big rim size. The Dyno time is to see the deal with the 95 Caprice as it is geting like 10 to 13 mtg and that sucks so somthing is wrong. My 95 SS Impala gis geting like 25 mtg with the 24" on it. If the dyno help at SD concepts with the mtg that will suck . I think I am going to put Meth Injection on the Caprice and a 155 Rocker on the intake and a 165 on the exhaust. My last thing if nothing works I will just go with a twin turbo set up. My Dad has the twin turbo SC concepts set up on his 94 SS Impala and that thing is nasty 11.08 is it best et. My trouble is just dont have the twin turbo money lol | |

Then stop worrying about how fast your car is. | |

Is your odometer still calibrated for the stock tire size? You might be going faster and traveling farther than you think. | |

| you've got a 95 LT1 caprice. Ok, so what is the rearend in it, is it a highway gear? 2:73? 2:93? is it a 9C1 car? My 94 LT1 car has a highway gear single in it.
95 impala ss cars had 3:08's in them. This would make it be a dog also? | |

| when my car was stock rearend,tranny and only intake and flowmasters on a 275/40 17 et street. it ran a 14.2 at 97 or 96.. those tires are shorter than stock. on stock tires and before a tune up it ran 15.1... tires make a differance also my wheels were a 1/3 of the weight of stock wheels (less rotating mass.) | |
