Steve, Powerdyne makes the compressor for these kits. Early on, these
kits shredded internal belts and were subject to bearing meltdown
when they were beat at the track on a hot day. What this means
is that if Duane had an early supercharged car, he would not
be a happy camper.
However, sometime during late 1996, Powerdyne addressed these problems
and redesigned the internals of the supercharger. Among one of the
changes was a switch from Kevlar to Fibreglass internal belts.
I believe this has solved the problem. (Though if your name is Duane
and you didn't hate forced induction so much, you'd probably pop for
ERT's _race_only_ Vortech supercharger setup [as opposed to ERT's
Powerdyne setup] .... the Vortech is completely gear driven, and
A side benefit is that the new redesigned Powerdynes are also very
very quiet. Almost no noise.
If you are considering buying the Dinan car, may I suggest you look
- The redesigned supercharger.
- Dinan's Vanos blocker. (Blocks Vanos out to reduce valve
overlap...which can be detrimental to forced-induction power)
- Cooling holes on the compressor which I believe Dinan implemented
on later setups.
One of the most knowledgeable people about Dinan's supercharged e36
setups (aside from Dinan themselves) is Chuck Quarton, who I believe
is also VP of the GCC. (I may be wrong on this.) He was on the
digest 2 years ago, but I don't know if he's still here. I do not
have his email address, but maybe one of our GCC members can point him
Other people on the digest who have or had ERT supercharged e36s are:
LinganC_at_aol.com, Jeff Tarr, fstbmwm3_at_yahoo.com (Vlasis), Matt Choi,
Mark Nernberg (of Pizza fame), and myself.
I am positive I am leaving some people out....
Anyways, I hope this helps.
Also, I may be a raging baboon, but I'm fairly confident I'm not
raging on this one. ;-)
