Little Gizmo in 4 sec to 100 km/h Ftt Kreidler engine, made by Luc Foekema

This is a heavy tuned Kreidler 90cc engine, original Kreidler cylinder with bore 53.7 mm stroke 39.7mm - 5 gears - Rotary valve - Ftt UltraSap ignition - Ftt calculated Exhaustpipe - Max power 30hp at 14.000rpm, with normal fuel 98 octan, no additions, beside lubrication 1:25 This test run was made Sept. 19, 2011 some days before te match. In less than 4 sec tot 100 km/h Topspeed in video is 106 km/h (at 150m about 130km/h) Km/h in 4 gears: 53 - 67 - 92 - 106 5th gear in video not used, the track is to short. The last Dutch Prostock record run over 150 meter was driven May, 2014 with time 6.62 sec, 0.01 sec reaction time. Which is 3.85 sec to 100km/h Ftt calculations for cylinder, combution chamber and Exhaustpipe exactly dedecated to your setup, The shortest and easiest way to realise the best performance possible of any twostroke and any ccm3. Just contact me by facebook or messenger or read: the comments of my Ftt calculations: https://www.facebook.com/notes/luc-foekema/comments-on-ftt-calculations/4094365256552 Profile: I started racing in 1964. Computers were still not there. I did hardly no calculation. With the advent of the computer everything has changed and complicated calculations are no problem any more. All old historical notes were struggling. In the past 15 years I got a number of programs. Beside I did developed many programs myself in Excel. It was my profession to do so for my employer for many years. In 2003 also began making calculations for third parties. Not everything, but a lot can be calculated very accurately for any twostroke engine. For instance the Exhaustpipe can be calculated in almost exactly the correct speed for which the setup and cylinder is optimal. Even by a large kart engines manufacturer (TM) was found to be not entirely correct. With a new calculated combustion chamber and Exhaustpipe it was far better then before. This is also partly due to the information I got from Jan Thiel and was freely available after retiring from Aprilia racing end 2007. Also the UltraSap ignition developed by my son Raimond was a very important part. The combustion and power are strongly influenced.

Prostock Dragrace Genemuiden 2008, less than 4 sec 0-100km/h
My fastest run ever was here https://www.youtube.com/watch?v=EnviMx6CLwQ I was born in 1943, startet 50cc racing in 1964 and I still enjoy twostroke tuning. Read everything about my racing career and all I wrote about twostroketuning, on facebook https://www.facebook.com/notes/luc-foekema/my-racing-profile/10203048642856 073 Genemuiden 1/2 final 2008: In this video me in the left lane against my friend Wiebe Plantinga, both on Kreidler, end time 150 meter 7.2 sec top speed 123km/h In that year one of the best times. Best ever 150 meter: 6.62 sec in NSSC Goes 2014 130.5 km/h NSSC Lisse 2013 My engine is a heavy modified Kreidler 90cc - air cooled - 5 speed - rotary valve - UltraSap ignition - only 98 octan BP petrol - 30hp at 14.000 rpm.. Ftt calculations are the fastest way to get the highest possible power in every two stroke engine. Just in 1 calculation and a good execution, you get that result. No need for futher experimentals. Example 24hp for a 50cc Kreidler engine is very high, but is absolutely not the end.

MAKING the JET BICYCLE
Why not put a massive pulse jet on the most rubbish bike to hand seems a cracking idea to me HAHAHA See jet ran van here http://youtu.be/BY-TYGpiGpU Making the jet here http://youtu.be/u5ceYtR22Ww Note:- When using liquid propane be sure you get the cylinders that are designed for liquid draw off Check my other pages for news and pictures Twitter https://twitter.com/colin_furze Instagram https://www.instagram.com/realcolinfurze/ Facebook https://www.facebook.com/Colin-furze-521680751253584 http://www.colinfurze.com song- Drugs Squad by march to the grave https://itunes.apple.com/us/album/drugs-squad/id506166537?i=506166702&uo=4"
