    Help me choose a new everything! Block/Heads/Cam

    the most efficient way to get a new engine is to buy a short, or long block since you want a good HCI combo with it. The reason being is that even if you use the stock block (which will need to go to a machine shop to get freshenned up before you can use it again) and buy the parts and install...

    cobra intake

    The cobra is designed to make a broad power band. It will choke power at the top a little compared to other freer flowing designs, but it also produces a whole lot of low end torque. It does this through its long runner design wich creates high port velocity. My NA combo used it with trick flow...

    How much power are headers,ud pullies worth on my (stock) motor?

    both the pullies and the headers are worth 5-10hp. Note the pinch at the top of the stock headers. this alone chokes the rest of the exhaust system. I have never seen a dyno shoot out where a header was worth less than 5. So adding the two together you get 10-20hp. Saving for a good manifold is...

    What size of Fuel Pump?

    here is an equation to calculate what HP a set of injectors will make safely. HP= ((lb/hr of the injectors)(8 or the number of cylenders)(.85 inj duty cycle)/(.5 or Brare specific fuel consumption)) Now the way you use it is by plugging in the injector size a the X value. HP=...

    My friend is getting a Camaro SS!!!!!

    To beet an LT1 you need to have similar power to weight as they have. they weigh a couple hundred pounds more than you so you only need like 250-260 engine HP. I was able to beet them with boltons and nothing more than 1.7:1 roller rockers to add some lift to the stock cam. If you have a full...

    Vortech SC trim vs. H/C/I

    If you are looking to spend less than 2gs on your car, neither HCI nor blowers are going to be good ideas. the reason being each costs about that much with out any tuning. If you want an HCI to idle propperly you will need tuning wich will put you overbudget. Worse, if you do not buy a good fuel...

    Intercoollers??

    The prupose of an intercooler is to cool the intake air temperature. Thats it. It is merely a side effect that you can run more boost and thereby make more power with them. The reason Vortechs do not come with them is a space issue. There is simply no place to put vortech's air to water...

    opinions needed

    I have to agree. 9,000 is a little expensive for a cobra with that many miles on it. If you can really get a GT in good condition for 4-5,000 then you have some thinking to do. The GT is a better car to modify as it costs less and there is nothing on the cobra so good that you would not replace...

    Q's about Zex Kits, Please inform!

    Nitroua on a stock engine is fine. As long as you get a well made kit and inatall it propperly with all the safety stuff you should have no problem. Most things i have read say not to go over a 125hp shot on the stock bottom end, but if it was my car I would keep it to a 75-100hp shot just to be...

    HP question for all you Techy's

    I make 420 at the wheels with HCI and a stock vortech. This is better than 100whp increase vortech claims because i made 275 whp NA. do the math and you see it added 145 whp. that is 45% higher than vortechs claims on a stock motor.

    boosted stock engine

    I am not a fan of turbos on autocross cars. Drift cars maybe, but not autocross. the way the power ramps up, they are much more difficult to get on while cornering. Mustangs do not corner well to begin with so having to worry about boost hitting while you are powering out of a corner is not...

    need help

    On my T-5 with 3.73s 80mph is at 3000rpm. Even with the blower I get 22-24mpg on the highway with them. 3.55s will be a little lower, maybe 2800rpm at 80mph and will get you maybe 1mpg more. The difference between the two is maybe a tenth in the quarte mile. So, is the extra couple hundred rpm...

    What Should I Do Next?

    What you do to your car greatly depends on what you want your car to do. If you want big dyno numbers go with some headers and then save for the heads. Stock headers are bad for HP. If you want to drag race, you need traction, in which case some control arms and subframes will help a lot. If you...

    Help me decide TFS TW or AFR 165 heads

    I run TFS TW heads. I wish I had saved up the money and gotten the AFRs. The reason is not based on power, but because the TFS TW heads fell apart in 6 months. TFS makes a good bare casting but its drivetrain components are garbage. AFR is made with better stuff and according to MM and FF make a...

    Need more power

    If you already have gears, do not waste money on buying 4.10s. You are better off spending the money elsewere. Your sign says nothing about headers, as you know 5.0 headers are bad. New headers will get you 5-15hp through out the power band for a minimal investment. The pullies you have not...

    Just got back from dyno #s low

    Regardless of your outcome, various dynoes measure the output differently by using different masses for your wheels to accelerate and different equations to calculate power. Also, some dynoes use correction factors as part of the equation some do not. I have had my car dynoed 3 times since the...

    Need help with door speaker wiring!

    When I ran speakers in my car I used the old wires by taping the new wires to them and when I pulled the old wires out they pulled the new ones through. Be very gentle otherwise they will pull off in the rubber thing which will ruin your day. But, these were not component [because I only wanted...

    PCV-Intake Oil Catcher...SEE here VIB!

    Ever since my car's been supercharged it has had a lot of oil preure problems. Neither the breather nor rerouting the oil lines to the supercharger have worked. When I drag race the dip stick gets blown part of the way out sometimes spewing oil on my headers. Not good. Will a catch can solve...

    Kenne Bell vs Centrifical

    For starters the kenne bell is a twin screw design supercharger that uses two unequl sized rotors to create boost with less heat than a typical eaton roots blower. A vortec unit is a centrifugal unit that acts like a turbo that is turned by the crank and not the exhaust energy. A vortec will...

    Check Engine Light?

    I do not worry much about the check engine light. Depending on your mods any one of a number of things can set it off. Since my car had a HCI and a vortec supercharger my cel is pretty much a "you engine is warmed up" light. I have had the the thing checked out many times and it has always been...
