Good day,  I am in the planning stages of constructing a monocoque for a F1 dublicate utilizing a 1000cc motorcycle engine (gsxr/zx,cbr...) it will be producing about 3-500hp being built and turbocharged.  I am working out the construction stages of building the monocoque and I will first be building a plug using pink panther insulating foam afterwards will be a 3 part split mold covering from the front to the back all the way up the middle then the upper piece will have two splits along the center line. I plan on using 8 layers of carbon with nomex 1/2" core sandwiched between them also it will have kevlar sandwiched between the two layers of carbon on either side of the core ex: C/C/K/C/C/Nomex/C/C/K/C/C.  I was planing to vacuum infuse the parts separately and will have to be done in stages with the first cloth layers being done then bonding the nomex core with wet layup after that finishing it with the rest as you can't infuse resin with a honeycomb cores.  My problem is how would the 3 section be finally bonded together and strengthen as it would need an overlap or additional layers where the bond would be but being a monocoque it would be difficult to reinforce it properly by the frontal area. 

You may find it more realistic to include a semi-structural space frame in the front section of the car.  You will need a space frame for roll bar backwards anyway (most road engines arent designed for structural use like in F1), so it might be easier to extend this forward around the cockpit and to include suspension pick ups up front.  If you then do all the roll bars, seat and harness pick up points to MSUK safety rules as in the Blue Book, then you can reassure anyone who might ask on the safety front.  Also means you will have the basic underpinnings to make it safe for use in some events like hillclimbs and some sprint series.  

Although as they have recently introduced engine/power limits to novice licence holders, so you may have to drive something lame to get enough signatures to go unlimited.
