[DML] Re: Turbos, transmissions etc



You are really doing your homework! This project sounds interesting.
The 200 HP limit is what Fred Dellis told us. If you look at the input
 shaft there is an extension on the input side of it with a large roll
pin through the splines. I suspect that is the problem. Remember I
said Legend Industries and DMC had to give out new car warranties so
they had to derate things to achieve some life. I heard Darryl
Tinnerset had special input shafts made up to solve this. The stock
PRV is a fairly low compression engine which allows for some boost
without internal modifacations. Of course the higher the levels of
boost you want the more you must modify the internals of the motor and
then the transmission. Boost is "progressive" anyway, you don't get it
at low RPM's. I found the Lambda enrichment in conjuction with the
enrichment on the CPR gives more than either individually. I am
running both on my Island Turbo install and neither by itself had much
effect, together they really make a difference. There is no low end
torque (which should help the trans take higher loads) but the power
just keeps comming and comming. I took some other Delorean owners out
for a demo the other day and had to teach them to stay in each gear
longer as the power just keeps comming on and on to the top of each
gear. IMHO the gearing is not right (the ratios) for the gears to
match the motor with the transmission once you add the turbos. Very
easy to tell if the dizzy has been recurved. You should see little or
no mechanical advance with a timing light. There should still be 20
degrees of vacuum advance so your total advance should be 20, not 40.
