D’oh meant 19 ! Will it go up hills and round corners ? Do you need pit crew ? James :-) Oh, yes, been designed to do just that :-) Thanks, but I have a long list of volunteers already :-) However, NO ONE will be working on the car apart from me. Only I know every nut and bolt and I am not prepared to put my life in the hands of someone else. If it goes tits up it will be my fault.

Are you planning any ducting for the radiator? Looks like air will take the easy route through the intercooler. I know of people having trouble getting air through angled radiators in the off road racing world. Didnt take too much angle to cause a lack of flow .

I know of people having trouble getting air through angled radiators in the off road racing world. Didnt take too much angle to cause a lack of flow . The plan is to run without ducting initially and monitor temperatures. As the car will be used for 1/4 mile, sprints and hillclimbing ducting may not be necessary. However, if it is I have already designed it in my head :-)

Too many projects, not enough time.

I use colour coding, blue for imperial and red for metric.

This thing is already an absolute monster and it's not even finished yet! Really impressive work Have you done any aero testing? I've been thinking up ways to do it low-budget for my Spit. So far my thinking has been taped tufts of wool, a camera and as many leaf blowers as I can rig up in unison...

Present work is based on what generally works, basic principles and advice from my aero guru. Leaf blowers won't give you enough air. Better to add the woof tufts and drive the car and have someone in another car following, in the front and by the side filming.

Car is away having the final touches added to the wiring loom so I am at a bit of a loose end (apart from working on the bonnet) so I have been surfing the internet looking for a cheap way to monitor tyre temperatures, F1 style :-) The F1 remote sensors are available but are around £800 each and I will need two, way too rich for me. However, a little surfing turned up these little beasties, $175 each without cases. They need to be connected to a data logger but my ECU (Life F88) has the capability to deal with this so no extra cost of a dedicated logger. With my car being very grip limited I need to find ways to make the most of what I have. Being able to monitor tyre temperatures for the whole run and over the entire tyre width, as opposed to someone simply pointing a temp gun at the tyres after the burnout, will provide a lot of useful data. Knowing how the tyre is interacting with the track will allow me to adjust tyre pressure, suspension and tracking to optimise the tyre performance over the whole 1/4 mile. Can't do any harm :-) www.izzeracing.com/products/infrared-temperature-sensors.html

Those tyre temp monitors look very useful and you will be getting so much data from every run. That is a long way from my first attempts at data logging with a 4 channel VELA device and a BBC B computer back in 1986/7!

You can never have too much 'useful' data, as long as you understand and can utilise it otherwise it can cloud the issue and send you down blind alleys. We must be of an age, well, maybe within 10 or so years :-) Postscript - Just checked and we are of an age :-)

I was drag racing from 1973 to 1993 so am sure we must have been at some of the same meetings. Here is a pic of my V8 Sprite with 5th wheel at Avon Park in 1987.

[/quote] Collecting data even then :-) That must have been pretty lively, what sort of 1/4 mile figures do you get? Santa Pod late 70s. Notice our team name on the tow truck :-) And again in the early 80s. Ended up running high 12s (on Dunlop SP Sport road tyres) with a lot of off the line wheel spin. Someone who knew how to drive would probably have got the car into the low to mid 12s York Raceway at the 1983 Street Racer Championships And at the 1984 Championships as the favourite for the under 8 cylinder class. I won this round but exploded a cam follower in the next :-( This resulted in the car being stored for 19 years before I started on this rather protracted rebuild.

I've been looking at those too. What else are you thinking of logging?

I've been looking at those too. What else are you thinking of logging? The price is too good to refuse :-) I have 4 wheel speed sensors and all the relevant engine fuel, air and oil pressure/temp sensors. I have been thinking about remote tyre pressure monitors. Caleb also offers a rather neat 3 axis G sensor which I was temped to add to my basket, but refrained for now. There will be trips by us and my daughter to the States in the next 12 months so there is no rush :-) Also, spreading the cost over a few months seems to make it less painful :-) www.izzeracing.com/products/6-DOF-CAN-Inertial-Measurement-Unit.html

That three axis inertial measurement device reminded me of another Data logging effort of mine trying to use a small pendulum on a low friction rotary potentiometer as an accelerometer in the Sprite. Once I got the right degree of damping sorted out I got to the line at the Pod - dropped the clutch...... and broke a half shaft....but from the data logger I knew it was 25 milliseconds later!! The best time on street tyres was a 12.9/110mph ...and like you, I still have the car as well! When you were racing, I was running Comp Altered so in a different pit area (ECA74 Vicious Trait and DCA4 Muscle Sprout, 1976 - 1985).
