Too bad cost for performance is not linear! In my investigations for performance improvements to the PRV, the price starts to jump when you get around the 200-225HP area. Much more than $80 per Horse. -----Original Message----- From: wingd2@xxxx [mailto:wingd2@xxxx] Sent: Thursday, November 01, 2001 12:46 AM To: dmcnews@xxxxxxxxxxxxxxx Subject: [DML] Re: fuel injector / HP Gains <SNIP> Now lets see, that's a 20 HP increase over stock for $1600, or about $80 per HP. The DMC Houston Hi-Po engine gives about a 70 HP increase over stock.....at $80 per HP that equals $5600, which is real close to the actual cost to have this work performed. Maybe we've just established another Delorean "standard" or "average" cost factor of $80 per HP for performance gains ??? How fa$t do you want to go ? Marty
