another superb find from the paul sandiford clearance, was this turn up of parts, lurking in the deep corner of the workshop,
which turn out to the basis of what we think was an original Sprintex Suercharged motor!
if i recall, Paul being the engineer, sud racer, and overall clever bod that he is, was asked to complete the build following limited success to get the thing running correctly, which Paul promptly did and ended up owning the whole car, after i think the project had put the original company into money worries! something like that anyway,
but essentially what we have here is this,
a block, crank, and piston and rod set, that are purposely prepared as detailed below, to run forced induction of whichever type you chose i suppose, supercharge or turbo.
i took the parts along to BLS to have Tom give them the visual once over, and help identify things so that i could be more accurate for you, and it appears that the components are as follows...
block, is a 1.5 sud block bored out to accept 87mm (1700cc) pistons.
theyre is further work on the inside to allow more room too.
the block is clean, and appears in good condition, with only some minor marks at the very top of the bores, which should clean up easily without the need for anything heavier than a hone i suspect.
the pistons are Forged and Dished to lower the compression to allow for forced induction, and i think they are American Arias pistons. these have had further work to the underside of the crown, presumably to balance and lighten further. all seem in good clean order, perfectly useable.
the pistons are sat atop standard AR rods, but have had a little balance work to the bottom pads, and have Cosworth Bolts modification,
these rods and pistons are all marked up as a matching 1-4 balanced set.
and finally, possibly the crem de la crem, is a Nick Humphries Race Crank.
this has been worked on and initialled by Nick, and includes Cross Drilling and other oil gallery work, and possibly, but hard to tell, possibly has been toughtruite/nitrite treated, impossible for me to tell, but this was quite typical of the Nick Humphries work of the era.
it looks in fine order, no tramlines in the bearings and surfaces, no evidence of any failures or damage whatsoever that i can see, so without a micrometer, i'm assuming its in good working order, maybe a polish and a check to be 100%.
detailed photo's can be found here
but its like this...
all enquiries or offers by reply or pm, delivery possible, blah blah blah, you know the score by now! ha ha!
so, throw a nice set of heads on, cam to suit (there are a set of Holbay Supercharge cams on ebay right now!), and decide on the weapon of your choice,
Supercharger / Turbocharger / Turbochargers! now theres a thought!!!
