    Crazy tire idea

    You can get speed rated snow tires , the snow tires police vehicles run are still speed rated up to 149 mph , but I am sure there would be some limmits on sizing . I have no clue other than that , I know snow tires are usually a sotfer rubber compound , and have siping , I think they would work...

    Help: S472 twins with LB7 stocker

    The exducer is a 88 , most refer to it as a 96 because thats the inducer size ( turbine OD ) the turbo itself is not the problem but not nothing else about the kit so its hard to help with out more detailed info , better start checking for leaks , and also checking to see what your commanding...

    Billlet S480

    The answer on re balancing very's greatly , Some say as long as the comp wheel is balanced its OK , but when i put a billet wheel in one of our turbo's I have them rebalanced , they are never out far when we have it re-done but it can make a difference between getting 15k or 30k miles before...

    S366 Turbo Question

    You better have aloooooot of fuel , and a few extra turbo's to swap in when it pops , but yes with enough fuel the billet S366's have hit those numbers , but its being pushed very hard to do so . Its best to pick a turbo that can hit the desired power in the "sweet spot" of the map , at...

    S366 Turbo Question

    Depending on engine mods to hit the power level you've posted you will likely need more than a standard S472 , I would say min a S475 , the S472 would maybe hit that # but would take a great deal of fuel to get you there , and either will be running close to there limit at 850 hp with out...

    I would bet you have a 96mm turbine , in the 83 turbine the loosest housing made ( from Borg Warner any way ) is a 1.25 , post the part # on it and i can find out what the specs are for sure .

    Performance Cam Question

    I usually shift a truck with that combo at around 3600 on the 12 , 2-3, 3-4 and 3700-3800 on the 4-5 . maybe more if I am tuning it in person and can feel how hard it is pulling at 3800, but with a stock engine I wouldnt go much higher than 3800 .

    S366 Turbo Question

    I would say the S472 is going to run around 150-200 deg cooler at 600 hp , depends on whether its a billet S366 or cast, turbine size , ect. There are so many variables to EGT's that its impossible to answer dean on, but that number is good enough for purchasing comparisons .

    Performance Cam Question

    My best on the stock cam in going by MPH and weight was around 1150 at the rear wheels .

    Performance Cam Question

    There are other benefits to cams besides peak power , but in a nut shell IMOP you need to decide what RPM you expect to run before a cam can be decided on , if you plan to stay under 4k and have a decent charger a mild cam would work good , if you plan to go higher a bigger cam could net you...

    main studs

    X2 , I have ran plenty with out them so it can be done , but considering the bolts need to be replaced any way ( one time use / torque to yield ) the extra cost to do main studs in worth it IMOP , and don't even change the cost of a build by more than a few hundred dollars once you subtract the...

    S366 Turbo Question

    The S466 will be about the same as the S366 , a tad more due to the larger turbine , but not all S466's have the same exducer size , so if its the "box" wheel it will be close , if its a sled pulling model with a 100mm + exducer it could be 200 HP more depending on specifics .
