Blair and I made it to the Blood Enterprises shop and met up with Dave Hunt just in time. Kevin showed up a few minutes later and we got to watch Dave convince the owner that this is the day scheduled to do the dyno work and we weren't going away.
Finally, things were straighten out and the car got on the dyno. Dave was running his laptop to tune the car while the dynoguy was operating the car on the dyno. Made several baseline runs so Dave could calibrate his O2 sensor software to the dyno set up. Then the first real pass the 74 2.0L made 73.5hp, not too bad. Then the work started with multiple runs adjusting the A/F curve trying to get the mix close and flat. Had to big spikes in it that had to be fixed. Almost 2 hours later the last pass produced 80.5hp and a better fuel curve without the big spikes.
I test drove the car and it was really smooth, lots of torque.

Were you guys just working on wide-open-throttle pulls, or did you do tuning under light loads too? Weren't the tuning problems Dave was having regarding light-load cruising? Did this get worked out? 80.5hp at the wheels sounds great for a 2.0 w/ stock internals. Brad/others, what's a baseline for comparison? (ie what will a stock d-jet 2.0 put to the ground?)

At any rate, congrats to Dave on the megasquirt conversion sucess. I'd say 80.5hp to the wheels is sucess indeed.

99.8 fully tuned Djet set on kill. Header/K+N/Euro P+C's with timing set at 30deg. on 91 octane... with quiet muffler (street legal) Open made 101 hp

80 some odd is perfect for a mid-high mileage engine with stock P+C's.

I think Mueller and I tuned something like 73-75 hp in less than 1 hour with the MS. Didnt really try because Mueller didnt want to spend the cashola...

I have tested bone stock high mileage engines with headers (no tuning) and have seen 75-80 quite frequently.

I think he done good.. << Gomer Pyle voice

Here are the recent dyno results for Ed Carlson's 2.0. He rebuilt his motor in '99 and it is stock except for the fact that he had it balanced and he has a Crane points replacement system. The stock d-jet seems to do a very good job.

Hooo doggies, some numbers to look forward too!! BTW, Once I get the stupid

engine in, what the drive train HP loss percentage? I'll be doing some tests on a

gtec, and tuning with that. (if I can tune) What else should I do while the engine is

out (to the engine)? I am converting back to fuel injection, and I will be cleaning the

engine as best I can. I also will be putting on aluminum valve covers I got for 20

bucks. Anything else I can do? I have a very limited budget, so im not going to do a

full blown rebuild. Im going to take the tin off, clean the grime off the engine and tin,

and paint the tin. I will also be fixing the battery tray rust, what should I use to take

off the surface rust so when I weld up metal and Por-15 it? Thanks guys!

it was interesting, and there were a few humorus moments. i think that the guy running the test was more accustomed to verticle gate shifters in big american iron. one run he put it in reverse. the car started crab crawling sideways across the drums. ' WHOA, YOU'VE GOT THE CAR IN REVERSE!!" geoff, blair and i were standing behind the the car at the time (IMG:style_emoticons/default/ohmy.gif) . "ah, you guys might want to stand off to one side". who says the shifters in these car can be a bit vague. don't feel bad about the money we throw at our cars. there was a nova/chevell there w/ a buick turbo v6 grand am engine, more other mods than i can remember. $40-50 g min. when did the topics/ replies start running so wide across the screen?

It does that when someone posts a large picture. Resize your pictures to something like 640 pixels wide or less before posting, and everything will stay nice - no horizontal scrolling.

How do you resize pictures? Do you need a special program? When I used the software that came with my HP scanner to crop the edges of a pic, the size ballooned from about 300k to over 2.0 mb! Same thing happens when I try to reduce the dimensions of a pic.

I use Adode Photoshop Elements to resize pics for the web
open the pic
go to Image>resize
set the dpi to 72, then the size to 640 hit ok
then File>save to web, set it to jpeg, then adjust it to high, and the file should be under 200k, then ok.
There you have a small for the web jpeg pic, about 640 which is about a 5x7pic.
You can do the avatars here too.

if you have Win2000, it comes with the "Microsoft Photo Editor" which lets you resize pictures easily.

the program is called "PhotoEd.exe" and can usually be found here:
C:\Program Files\Common Files\Microsoft Shared\PhotoEd


open the pic with it, go to the "Image" then "Resize",
select "Pixels" as the "Unit" and specify a new size ...
then save ...

There are a ton of programs out there that will resize pictures, Photoshop, photo deluxe, image expert, photo impact illustrator etc.

Chances are if you ever purchased a digital camera the software that comes with the camera will include a photo editor.

Microsoft Photo Editor sucks!!! Actually it works ok and has a decent interface but the quality of the jpegs it makes sucks. Irfanview will produce a much higher quality end product. Irfanview is a little harder to learn though. Some of the things it will do are not intuitive. I also like Irfanview's batch features. For example you can easily could reduce, sharpen, and save a whole folders worth of photos.

Photoshop Elements is $99 and it does tons of editing. Well worth the $$
Course I take tons of pics with the digital and Monique has won 2nd prize ($300) in a local photo contest. I have them printed at Ofoto.com, all online uploading/ordering.
