johns tvr rebuild part two

[Engineer1949]

got a couple of bits done today fitted the extra capacity lower tank to the expansion tank,and modified the throttle linkage, with the sc blower the plenum goes on round the other way so the throttle cable has to go through 360 degrees to operate the butterfly leaving a woolly feel to the pedal, so i have modified the linkage it now will have a solid link from where the cable used to attach to a machined quadrant which then has the cable direct to it from the inner wing, shortens the cable to so should be much improved ,also turned up a couple of top hat washers in stainless to fit into the existing speed sensor bracket which in turn accepts the racetech speed sensor for the new dash.

what`s that aluminium thing ?

[Engineer1949]

The threaded object is the speed sensor for the dasp2 pro and the large tank is the coolant expansion tank.

another day some more work, got the pulley of the blower and fitted the 80mm diameter one should now produce around 10psi also got the new green giant injectors fitted plus all the sundries vac pipes pressure pipes coils packs blower oil reservoir etc., managed to source the new length belt for the blower amazingly its only 14mm longer so getting there ,should have the new dash blank on friday so can get started on the dash2 pro install should be fun not least of all working out the number of pulses per mile from the speed sensor,

Looking fantastic :-)

John, will those new injectors supply adequate fuel or are you still going to have to use a rising rate regulator.

[Engineer1949]

The original thinking was rising rate but these can shift 440 cc/m so plenty of fueling available partly why i went for the giants as opposed to red top.

Hi John, the car's coming along brilliantly as always! I'm really interested in your throttle cable mod - this is a problem I've always suffered with too - Would you be able to post or send me a few more detail shots of your solution as I'd really like to do something similar - possibly commission you to knock up another linkage if it's a custom made part?

[Sardonicus]

John just my cents worth by I would seriously reconsider where you currently have the IAT sensor mounted trumpet base thermal insulator fitted or not keep up the good work

[Engineer1949]

I will get some good shots of the finished article i am waiting for the clevis linkage ends to arrive once done will post pics and yes i could easily make another if you supplied your original

The temp sensor has never been a problem it is as you suggest in a heat protecting medium plus the plenum is insulated from the manifold hot starts ert. never been a problem.

got some way to installing the new dash stripped out all the required elements from the old set up sorted the wiring which we now dont need and started wiring up the dash2 pro.

john

[SILICONEKID343HP]

Do you have one of those water cutter things ?

[Engineer1949]

I havent but i know a man who does although the dash was cut on a cnc mill designed for dashs control boards etc it can engrave as well cool piece of kit

Hi John out of interest what is the diameter of your intercooling pipe work bud ?

[Engineer1949]

got some more done today mostly wiring up the dash2 just a couple of not very good pics.


john

[Engineer1949]

Sorry for the delay intercooler pipe size is 62mm od 1.25mm wall thickness.

Hi John cheers for the reply , its a great help !! Great work as always, the Chimaera looks very !! Can't wait to see the wedge finished

[Engineer1949]

yes work seems to get in the way want to get the wedge painted before the bad weather, been finishing the reversing throttle linkage so as the back to front plenum dosent have to have a cable going right round in a circle taken a bit of working out always seems simple at first glance anyway heres some pics see what you think.


john

[jojackson4]

Nice way of doing it looks good

[Engineer1949]

a bit more done today got the track day inserts for the tailpipes fabricated, it hasent been to much of a problem but it only just squeaked through at bedford so got to be prepared and as i am upping the engine output might be a bit louder.
