Fairly safe to 10 thou under, beyond that the Induction hardening Toyota use just doesn't go deep enough so they need to be niterided which adds a good deal of time/expense as there's a heat treating/straightening process involved as well. (went through all this with my 7M cranks)
You need a flow map for your Turbo to work out the CFM @ a given pressure ratio then I have the data for up to 3" pipes below.
2" piping
1.57 x 2 = 3.14 sq in
300 cfm = 156 mph = 0.20 mach
400 cfm = 208 mph = 0.27 mach
500 cfm = 261 mph = 0.34 mach
585 cfm max = 304 mph = 0.40 mach...
Yeah it was but these days "LS" denotes the LS1 and later all aluminium series of engines, even back in the day "L" was the more common varient, there was an LS34,1,3 and 6 from memory, the more desirable engines were the ZL's ;)
It's NOT a kickdown cable... :nono:
It's for line pressure and yes it would need to be set up but it's not all that difficult to do, Yes the Jz Bellhousing bolts to the 7M trans, Yes the TC will bolt to a Jz Bellhousing but as I said you have to use the 7M TC as the input splines are...
You need to size the IC piping to keep the air under mach .4 (304mph) above this friction becomes a factor heating the charge air.
re the original question, there's no "flow" through the nipple being closed at it's end by the sensor/gauge so no speed.
Air is a fluid....
Better tell all the Aviation guys the Bernoulli Principle doesn't apply to aerofoils before their planes fall from the sky... :nono:
