A hoist is the present to yourself that never stops giving .

Laying on the concrete gets old really quick.

I find getting down on the concrete the easy part getting up is more challenging

A hoist is definitely on the wish list, it's not getting up or down that's the issue, it's doing it 20 or 30 times that wears thin. I was ready to throw the billet servo piston over the back fence and put the stock one back in.

Success



It wasn't all roses, took me all night to get there, first run left in 2nd, second run shifted straight from 1st to 3rd, 3 run left in 2nd again, 4th run shifted into top but them bumped it back into 2nd, 5th and final run I finally managed to get through all 3 gears into the correct order and ran a new PB for this car. I'm going to have to look a little more closely at the shifter to see if I can make it a little more reliable.

Into the 13's, you are heading in the right direction.

Well it turns out that 4 foot of RHS is slightly cheaper than a $500 set of Caltracs, doesn't take 2-3 weeks to get here and on top of that, they don't actually make Caltracs specifically for the Gremlin.:



Some time later after a bit of welding and painting (note that the shock mount needed to be incorporated on the driver's side:



And installed on the car, still need to get some rubber bumpers for them:



Also did some work on the shifter gate to hopefully reduce the number of shifting errors:



Now it can shift between 1st and 2nd without pressing the button and going to either neutral of 3rd requires a button press (remember this is reverse pattern now)

Now this is seriously cool. I love the idea of building stuff not buying.

Hit the track again this week and my special new race shifter solved all of my gear selection problems, I’m pretty happy with that

The slapper bars seem to be working as intended but didn't really yield any significant gains on the strip. I did manage to run a new PB of 13.985 @ 98.4 mph, but that's only slightly better than last weeks 13.995 @ 98.1. The 60' times didn't improve at all, so maybe I've hit the wall as far as getting it off the line goes.

Little bit of video of the slapper bars in action:

Looks like it's time for that cam change:



It's had a noisy lifter for a while, I guess now I know why:

That's a lot of lifter height difference.
What does the cam lobe look like?

Fark! My next cam will probably be a roller. Might go all girly too & put some juice in it.

Cam looks like this:



It is an old engine of unknown history, so I guess this sort of thing is to be expected. It's lost 0.073" off the lifter and 0.105" off the lobe, so is making about 0.229" lift at the valve (1.6 rockers) compared to 0.512" from the cam spec. This is an exhaust valve, all the rest seem ok.

The real question is how much HP has this been costing me. The cam that came out is a Crane H-272-2, and actually has a fairly similar spec to the Comp XE262H that I was going to put in, so will I see a benefit from just fixing the problem or do I need to go bigger?
