I decided not to paint the whole car white. I wanted to do a two tone paint job with black gravel guard coating on all the aero bits but I thought maybe that would not look that great . I did find a white Fiero with grey aero and lower bumper covers and I thought it looked good so that’s what I am doing. I have four cans of the grey that the car was painted with from 7 years or so and compared to the white cans this stuff is amazing. I do not know what they changed but this stuff doesn’t drip and using it in around plus 4 C temperature it glosses up evenly and looks great. The new white cans have been nothing but aggravation. Any way here is the lower half of the rear bumper:

Got the bottom of the doors and area in front of rear wheels done over the last couple of days. Slow going because of lots of sanding to get rid of splatter.

Bought a Simonize buffer/polisher the other day. It has a hook and loop base and I wondered if I could get a synthetic steel wool pad to stick to it to speed up the sanding process.





I am amazed how well that works.

Since I am waiting to get more paint and we all have time on our hands I decided to build a 4 lane 1/24 scale slot car track. Coming along nicely should have all the wood work done in a week or so.

Here is a short video (1 of 15 or so) https://www.youtube.com/wat...leA&feature=youtu.be

Track is almost done(each lane gets colour coded with pinstripes next)



Back to work on the Fiero soon.

I put the insurance on the car so I could test it out since I have not driven it since making all the changes to the turbo and intake and charge piping. I am happy to report that the car is running much better now. First drive I popped a charge pipe hose off. Fixed that, was a clamp I forgot to tighten up. Second drive, popped another hose off. Different spot, changed to a better clamp, tried again and everything went really well. Today I took it out and ran a scan on it with my HP tuners. With it set at 11 psi max boost I ran it through the lower gears up to 6700 RPM and the scans show everything in the green and only the odd KR of .1 to .4 degrees. And that was in totally random places, not where I thought I woud see KR.

For once I accompished everything I set out to do with this mod. The smaller turbo spools up quicker, it has more power when I leave it in fifth at low speeds and floor it. Intake air temps never went above 28 C (23C out at time of drive). Nothing leaks, I am happy.

But I am probably not going to drive it much till the fall or maybe next year. I took advantage of being able to drive with expired plate stickers because of covid19, so if I turn in the plates now I can avoid getting stung with a 2 year bill next may. In Ontario if you do not turn in the plates when the car is not insured, they ding you for the year it sat anyways. There might be a way I can avoid buying new plates next year, saving 40.00 but I will talk to the Service Ontario people on Monday.

I do not want to drive it until I can finsh the paint job. As you can see, the car looks like sh!t. There are so many little things I want to fix and finish that driving it now is just going to delay things. I have new headlight lenses to put on, I need some new pieces of trim and hope to pick up some rear lower quarters at the wreckers once they open. I am going to take off the aero bits, fenders, rear bumper and door skins so I can do them up right and get the fit right for once. And finally get some new dew wipes on. I will probably miss the track again this year oh well.

My tune turned out to be not as perfect as I thought. Yesterday, thinking I had everything right, I took the gopro and went for a spin. At about 6400 RPM I was getting a drop in power sometimes. So I decided to not publish that video. I took a look at the tune and the problem was that I forgot to look at the power enrich spark tables and they still had a huge amount of advance reduction at higher rpm's. I didn't notice it the other day because I did not put the pedal close enough to the floor to get PE to come in to play. A scan does not tell you what spark table you are running off of, just the amount of advance and KR at the time. So I put the PE spark tables back to stock and that problem got solved. The PE timing is abit too aggresive now, I am getting some KR from about 4400 to 6500 rpm. I can take some timing out of the PE tables to fix this or I can up the amount of watermeth injection. It is set to come on at 4 psi and hit max at about 14 psi. Setting the max at about 8 psi should do the trick. The whole KR episode starts and ends in 4/1000 of a second if I am reading the graph right.

I made another video today, uploading it now.
