shorter gears will always make a car faster if top speed is not a consideration. shifting too many times can fubar that, but brrp, bbrp, brrp, is always better. this is simply because hp is torque divided by time. time, time, time. formula 1 teams are consantly improving shift times to nearly .1...

on B and K series honda engines, 7s are just fine with fi. i'm thinking where you are is cool all the time and fi friendly. go back to 6s and see, but it does sound more like tune is off. i think that 7s will run even in a properly tuned n/a car, they would just give very poor cold start and...

i agree. aem has released v3 of their software, but right now, iat is not something that can trigger an event like pull timing quick. whipples are better than roots chargers, but they all make tremendous heat. 6psi isn't too high though. i've seen them actually reset the iat sensor on aem tuned...

sorry, guess i gave you guys too much useful info. bov and divertor are the same. you are just making them different because of how the air is account for by the ecu. yes, the germans has been doing turbo forever. their management systems use a mass aif flow or maf to determine the air going...

sorry, but there is no 'magic' a/f ratio. check out one of efi101.com's newsletters. there's even a government paper on it from ww2 fighter planes. not that we can trust them today but back then they had superchargers on v-16 planes to kick some ass. i have found many aftermarket widebands to...

looks like a winner here. the s/c has enough displacement for the engine (a 3.5 yes!) and the i/c plenty of capacity. the important thing here is in boost cooling and recovery. if iats are 95 or so at start of pulls and peak 130 then back down to 95 in 10 seconds or so, then the i/c and heat...

important thing to remember is that nitrous adds SERIOUS cyclinder pressure, just like a turbo does. in fact, i have seen it, and if you're a frequent track junkie, you will too. n20 will often beat a turbo. that's because the extra oxygen is the "fuel" the engine needs to make power while the...

i'm guessing you mean iat (intake air temp) after the supercharger vs. before where the stock iat is? the diff. is HUGE. any roots-type s/c will skyrocket the iat. i have seen iats actually cycle the sensor. that is, it gets so hot that the sensor goes from peak to a disconnect value. on...

WOW, i've never seen so much keyboard wasted on such a simple thing. gear ratio is about where you RETURN on you shift rather than all these things listed. an exception is track racing where extending your time in a gear to get into a corner could be critical. also, in this case, perhaps, top...

guys, take off your egos. whatever you want to call it, what we want to do is relieve the intake track of pressure from whatever it is we're presurizing it with. call it whatever you like, but when you drop throttle, the pressure needs to go away. on a turbo it's because it can send a...

lw flywheel simply affects how the clutch engagement works. w/o a flywheel, the engine will die quick when you try to engage the clutch. add a/c to this and it's worse. example, just a clutch without a spring pack will make take off from a start very hard. the springs absord the kinetic energy...
