    ABS retro-fit

    It took me a little while to find out what a plymouth arrow was! The ABS is there I believe to assist the driver in adverse conditions, particularly as the fuel load is at least 100lt and is positioned behind the rear axle. Thank you for the information.

    ABS retro-fit

    Good to know...production cars are far too complicated for me!

    ABS retro-fit

    Yes, probably true, but is an endurance racecar from a major manufacturer in the UK. I believe the Daytona Reps produced in Melbourne have an ABS system adapted from a current HSV and partially controlled through a motec dash.

    ABS inputs

    With the current upper market segment ABS units, what inputs do the ECU's require and why? Obviously the wheel speed sensors are required, but why are some of the other inputs important?

    ABS retro-fit

    Has anyone seen an ABS system retro-fitted to a vehicle not originally designed for it? The reason I ask is that I have recently received information from a respected driver about a new vehicle he has just tested (sorry cannot disclose it). It has switchable ABS. With ABS braking was described...

    Weber 45 DCOE Aux venturi design

    Weber and Dell Orto have seemed to produce essentially similar products for some time. However weber seem to have followed some of Dell Orto designs with the more recent DCOE's. The Aux venturi in model 150 and some 152 DCOE's have become long, full body Aux venturi's. Does anyone have any...

    Engine tilting

    The whole suspension will be bespoke to the vehicle.

    Engine tilting

    I've rearranged the rear end a bit and should be able to get the angles I want for a 14 degree tilt.

    Engine tilting

    No the engine remains E/W and is moved from the front to the mid-rear position ala' Toyota MR2.

    suspension bellcrank bearings

    In a pushrod suspension, compressing the spring and damper via a bellcrank, much attention is placed on the bearings used in the bellcrank. In formula cars these bellcranks are in single shear and attach to the tub via a stiff post embedded into the tub. With a different application, i.e. using...

    Front/rear track width effects

    an update for those who may be interested. Going through my database of front/rear track differences in sportscars a new fact has come to the fore. When I compared F/R track in cars released in the last 4 years the ratio has changed from that previously noted. It is now 3:1 wider at the front...

    Engine tilting

    Thanks, I had missed the first thread, which is the one that seems most relevant. I will investigate further the engine's oil circuit and see how the drain-back to the sump is arranged. For this chassis I will tilt the engine (assuming the drain back seems sufficient) and see how it goes. The...

    Engine tilting

    mid engined, rwd vehicle for motorsport use. Using the FWD transverse engine/transmission relocated to mid/rear engine.

    Engine tilting

    Well it never rains it pours!...the angle is in reality 23 degrees! This will enable level driveshafts, but again how much is too much WRT rotation of the engine?

    High Speed Rebound, needless?

    Bildon, with the information received from PT and Claude, what will your decision be WRT the dampers and why?

    Real world loads

    Interesting days then. Interestingly a rally engineer I recently spoke to suggested 8-5-5 for the 'G'. Why I found this interesting was that WRC cars seem to have very good levels of travel...but then they do seem to hit a lot of things in a rally.

    Engine tilting

    Many thanks, I will check oil levels and drain back when the engine is running. The other option was to rotate the gearbox relative to the engine, but this is much more work than simply tilting the whole lot!

    Engine tilting

    I am in the process of making an attribute mockup of a individually constructed vehicle. I will be using a Mitsubishi 6G75 V6 engine and 5 spd manual gearbox. To get the drive output to the height I require I need to raise it 45mm. The simplest means is to tilt the engine/gearbox 12 degrees...
