[DML] Re: fuel injector / HP Gains

[DMCVegas@xxxx]

Just to let you know, there is also a setup from the Alpine which is 
6 single carbs! I was unaware of the cost for the 3 carbs, so that is 
new info.

I believe it was said in the back issues some time ago that the CIS 
system used on the DeLorean is capable of feeding a 250hp engine. But 
with carbs, CIS, or EFI, one thing remains: The exhaust will have to 
be modified. Don't get me wrong, the stock exhaust creates a nice 
tone, and is well suited to the car. Or I should say rather for the 
car designed for economy. But because of it's restrictions, it will 
have to go. No matter what you do, higher compression, port & polish, 
high flow intake, increased fuel delievery by means of whatever fuel 
delivery system, one thing remains: You will have to remove the 
restrictive exhaust & emissions control system.

Case in point. On pages 121 & 124 of the 1977-1995 edition of the 
DeLorean GOld Portfolio, the artice states that the european version 
of the DeLorean PRV is able to put out 156hp. This is w/o the 
emmisions system. As a side note, it also states that fuel economy is 
shot. Unfortunatly, there is no picture available of the exhaust 
system on this engine. But if I had to guess, I would imagine the 
catalytic converter has been removed, along with the LAMBDA probe, 
ECU, and the frequency valve. On the DOC's webpage about the freeflow 
exhaust, minus the muffler, this exhaust in completly redesigned. 
Here the output from he engine is 167hp. In both cases, the amount of 
fuel fed to the engine is increased. BUT ONLY BECAUSE THE EXAHAUST 
SYSTEM CAN QUICKLY DISPOSE OF ALL WASTE FROM THE ENGINE!

Bottom line: With the stock exhaust system on the DeLorean, the only 
adantages that I can see with the proposed EFI system would be for 
fuel economy & cleaner emissions. If you want better performance, 
start at the tailpipe, and make your way back. Granted if your engine 
is out tune, an EFI system can make the best of things to give the 
best performance/economy possible. But even then, the engine isn't 
running up to par, so it will be technicly running worse than factory 
specs.
