hey guys
well it has been quite a while since this car has seen the light of day so here it is
the chassis is almost complete with only a couple of bars being needed for the roll cage and engine work has started car can be lifted by 3 guys without any worries gives you an indication of weight i am hoping for 850kg full wet weight (including driver)
I wouldn't be too worried about big bumps on a drag strip, but more about the constant downward pressure under accelleration.
Do you guys have some plans to beef up the mounts at all?
hey guys
the rear coilover mounts should be fine as i am running 90/10 shocks there will be very small movement also as i wind up the power/speed i have made provisions for wheelie bars and chute (see rear hatch photo) the wheelie bars will also absorb any load. I feel that most force applyed to the rear mounts will be in the initial 60ft as the weight transfer will be greatest at this point.
Nice work!, but I do agree those shock mounts look a bit light and might want to twist off that cross bar. On a drag strip you might get away with tit though, maybe....
Ummm theres been a lot of time and effort gone into fabricating up that juicy looking rear end but what screams at me is WHY?
The trailing arms look nice and light but all that added clobber/panhard rod and dare i say this: An "almost" De-Dion tube in there couldnt weigh a lot less than the stock trailing arms or at least some fabricated tubular trailing arms which would have been my choice.
How come youve gone down the "live axle" road on what ultimately only gets pulled along for the ride?
There is a significant down angle of the Panhard rod as well resulting in a fair sideways arc of the entire rear end ( a typical downside of a Panhard rod) unless you fabricate a fairly substantial horn to drop the chassis pickup point down the the suspension pickup point height.
Id be looking hard at this.
Not always feasable tho depending on the setup.
rear suspension movement will be fairly limited with the addition of those wheelie bars but nonetheless, Its still there.
A simple Watts link setup would solve your drama. farily easy to fabricate and since the pickup points are sharing load in both compression AND tension, the pickup points can be made extremely light with surprisingly small tie rod ends.
Even the center bearing assy would only have to be very light.
Secondly, those shock mounts will never actually break but that single and unsupported crossbar will be subject to some twisting AND bending up and down and just about any movement in there is undesireable.
I realise you have gone to lengths to have the shocks working perpendicular to the swing arc of the rear tube but the shocks angle barely a few degrees more and one major part of the issue dissappears and not cause any operation issues at all.
Just what I see M8.
Nice work. Keep us informed.

Mate i remember this car from quite a few years back.
I'm curious as i own a previous gearbox from the car which i am running now, the bellhousing is painted green, anything in particular different about it? Seems to be holding up well compared to other boxes ive had??
Fill me in......?

hey mate the only modification (if it is the standard e15 box which was our first box) it was just rebuilt and cryogenically treated mate our next gear box is a pintara gearbox which is in my neighbours n12 exa vert he brought our last setup
confirmed! you hinted at this engine a while back but didn't say for sure. will be interesting to see how it goes.
yeah ash well our research has told us that these engines are extremely strong and we will enjoy doing something different to an sr/ca swap
also tass i will pm you and discuss this with you i am very interested and you have made some good points
