Hello, Exist some old tricks - recommendations for quick changes during fine dyno tuning to maximize power ?? (racing old style engine) for example: different fuel carb. height change (differet spacer) antireverse plate exhaust tailpipe diameter change etc etc Thanks for any tips Radek

Hi, what is Throttle body diemeter requirement for V6 engine? 2800 ccm 200hp target 7000RPM Thank You for ideas Radek

Hello, How way intake runner surface affects flow numbers and power results? (two same runner volume with different surface) (rough vs smooth) Thank You Radek

Hello, What is minimum (ideal) Quench dimension for flat-top pistons? Piston to head distance for racing engine. Thanks Radek

Hello , How way the asymmetry of the toe alignment (thrust angle) affects tire wear and car stability? Thank you Radek

Hello all, What is racing tire vertical load dependency (spring rate sensitivity) on wheel instant inclination angle? During cornering (body roll) Exist difference between radial and crossply tires? Exist generally difference between radial and crossply tires load dependency behavior? Thank...

Hello, exist recommendation for minimum flywheel weight? how way is harmony ballancer improtant? we build racing engine and try minimize engine inertia thank for all comments, Radek

Hello, Following the previous thread, What is tire vertical stiffness effect on handling, performance and cornering balance? what effect on balance during lateral load transfer? if vertical stiffness is affected with rim width,what tire load sensitivity? Thanks, Radek

Hello , is possible (helpful) to measure and compare the tire lateral stiffness in garage conditions? Thank You for ideas and opinions Radek

Hello, How much is usually acceptable king pin offset and scrub radius value for high powered FWD cars? thank you for experiences Radek

Hello, How racing tire is sensitive on any toe changes over full lateral load range? for example: Is toe-out (always) more significant change when tire approach his lateral limit ? Is same effect for both axles? Is just reason why want minimum compliance steer,roll steer on rear axle? Thank you...

Hello , How is defined the usable range for roll center height in racing conditions? How is possible to fight against bad RCH ? (how effective is?) Thanks for opinions Radek

Hello, how is defined "rear axle sideslip stiffness"? how does this value affect handling and performance? Thank you for explanation,

Hello, we can hypothetically determine, or give an examples: how way understeer gradient affects lap time results?? probably transitional state will different than steady state level requirement Thanks for expeiences

Hello experts, I am very interested about suspension lateral compliance data, exist some database or real examples toe and camber lateral stiffness for modern passenger cars or racing cars? or can we determine some ussual target values we want to achieve? Thanks for the answers

Hello All , How scrub radius affects steering feel when car approach lateral grip limit? driver complains for very bad tire response is FWD car which have really big wheel spacers but only 2 degree caster and 14 degree KPI he suffers also strong torque steer under acceleration..........is...

Hello All, what compound affect real tire grip? is softer compoud really faster? or depends only on teperature? ( then max grip at ideal temperature is same? ) Thank you for real experiences! Radek

Hi, how significant toe and camber affect car straight ride resistance? (top speed for example) what tire width and aspect ratio affect this all? (of course racing tires :-)) again Thank You Radek

Hello, what general effect same tire wide mounting on various rim wide? tire cornering stiffness,vertical stiffness,slip angle,etc. how affect cornering performance ? Thank You Radek

Hi guys! Can you tell me something about roller rockers? Is there any benefits between original rocker arms and roller rocker arms if stay on same arm ratio? I wondering how much influence does to the friction losses? Is there any benefits if i use lighter roller rocker? Thank you for ideas Radek
