Yes but what good is going and buying a tap going to do if it's not the correct freak helicoil size?
I'm sure Aaron will make it right when he's made aware of this as it's an issue that could affect other customers.
Now the problem is going to be when you run the correct 14tpi tap into the 13tpi holes you're going to change the thread form again....
If it were me I'd buy a set of 10mm Keenserts, these use a 14x1.5mm tap and have locking pegs to prevent them backing out ever.
Most times when the studs...
Yep but Helicoil sneakily made it so the next size up tap is too small so you HAVE to use theirs!
This is what I meant earlier by you can't "nest" coils to reduce a hole size and the Inserts won't screw into each other.
Done a bit of research and can't find mention of a 7/16-13 tpi tap.
The Helicoil part number is 91709A108 for the corrct tap.
I stand by my earlier post though the Helicoil taps AREN'T standard forms sizes meaning you CAN'T go and buy a 7/16-14 tap and use it for the inserts.
There's a bunch of online calculators like this one where you just punch in the numbers that will give an approximation BJ.
All you need are the base numbers Bore/stroke/Combustion chamber volume/Piston dish/Piston protrusion/gasket thickness and bore size.
I gave up trying to find em.....
Ended up using DTM female pins and silicone then a short fly lead and Deutsch plugs.
Drove mine a few times 1:1 and it was horrid the "curve" makes it so much nicer.
