Hmm. My Opel GT miata turbo project might be a good mileage machine. 1900 lbs, fairly slick.

I can get anywhere from 30 to 15MPG on the road depending on how I drive, (much less on the track) I have 550 apparently (suppose to be 440) injectors. I have a Mark1 link with a AEM wideband, modified for temp comp, no sequential yet. I am thinking the engine only has so much mileage performance in it, the camshaft may well yield more performance. My 97 1Z TDI diesel gets from 35 pulling a Large 2 Harley trailer thru the mountains at high speed, to 47mpg at 65 cruize set on any trip, and has 100+ hp with over 200ftlbs torque, just off idle. I have been unable to improve on 47, at the speeds I am willing to drive, with much injection timing tinkering. This car also has excellent aerodynamics, which the miata lacks, The VW pickup truck I have with brand new injection components, and IDI motor, is lucky to get 40, usually gets 35 at speeds around here (65 being minimum).with AIR! It also has atrocious aero, even with the cap, but I know mileage gets better at moderate speeds, this ain't the first pickup I have owened. Point is, if you get 40.with the ability to go 100MPH that would be outstanding. I would be totally amazed it you can get 50, even at 55MPH. OTOH the 79' fiesta with a webber carb VW engine ( IIRC1.6) got 45MPG (easy) at 65MPH+ light with crappy areo. So YMMV CB -----Original Message----[CB] w From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Robert McElwee Sent: Tuesday, August 26, 2008 6:23 PM To: Tony Cooper Cc: Bill Cardell; [email protected] Subject: MPG (was Dyno Results from Changing from a Link to a Hydra) I just swapped out the injectors in my MPG car (went from the 440's back to OEM) and had to decide whether or not to hack up the stock harness for sequential. I was hoping there was a significant difference so I stuck with sequential for the new injectors. I am installing some #4 heat range plugs with larger gaps in the MPG car today. Trying to chase down the miss fire problem I am having. I know people over estimate the MPG they get on their Miatas but DAMN I have been stuck at 35 MPG for weeks and can't get over that hump. I need to get the car out on the interstate for a nice long drive to see what my MPGs really are. I just can't understand how people are getting 28-30 on a stock Miata and my modified car doesn't get much better . I think it is time to check my speedometer against the GPS because I should be higher than this. I am running stock 14" 7-spoke wheels so I would figure my speed should be spot on but you never know.
