Poll: Who has ever hit the rev limiter?

[5ABI VT]

Bumped it about 10x last week when I took it out. have to get a feel for where it is on the tach because they aren't exactly accurate. Pretty much figured it out now. I have no fear with this motor at all. if it blows up oh well stroker time

Tach calibration is a relatively easy DIY fix for anyone familiar with basic electricity; just soldering in a resistor in place of the deteriorated, printed one.

I believe Dynomite (our club's Archive guru) has the procedure captured in his archive. Check there first. Or, I have a copy of the article I wrote on it...somewhere around here if you need me to dig it up for ya!



Course too, with any analog meter (tach in this case) there is a certain % of lag which increases with changing (rpm) rate; naturally there's more in first gear especially. SO...a shift light is recommended. And, in the archives too is procedures for installing one. (I installed a Raptor light which is small enough to be hidden behind one of the vent grills. All seven LEDs wink on and off in sequence when the ignition is first turned on - as a test mode.)



In the book, "Heart of the Beast" there was a problem discovered when a single chain was used. But, the cure was the double chain that the LT5s have now. In the book, it describes how Lotus engineers tested the motor by alternating the engine between peak torque and 7000 rpm for a little more than a week w/o issues. So, I don't think occasionally hitting the limiter at approx 7200 is "pushing it" at all, long as it hasn't been run out of oil or the like. It ain't no pushrod motor!

And just for the record I hit it twice because I needed to know where it was after all the mods lol.
