My name was "Eric Allred", and I was the one telling you what jetting to change to. I was also there telling you to change the damed timing from 22 degrees total advance to 32 total advance.
I'd like to hear what "the" change that "did it" was. Those two things changed, along with stuffing paper towels around the leaking banjo fitting that you went from 74mph to 101mph. I also told you to shift when it first started to pop rather than try to wing it up through the rpms which made a big difference as well.
Next year if I go out there, i'm spectating ONLY, you guys can all tune your own cars. Good luck out there!

Hi Eric! I'm so sorry to have flubbed your name, especially since I truly am grateful for your help.
I believe the thing that "did it" was the elimination of the oil mist. There wasn't a single good gear on any run until after the oil leak was surrounded with rags. Yes, you apparently already made note of this, too. Sorry if my saying I didn't think the jetting was "the" thing pissed you off (as it apparently did) - I was hoping people might read the whole story instead of getting excerpts, but I guess we're a sound-bite nation these days.
As for shifting with popping - I was so damned tired I don't recall that. _I_ was running on fumes (nomatter how coherent I may have seemed) - serious lack of sleep. However, I do remember learning just how flat the torque curve is on that engine! Three runs with VERY different shifting patterns and all within one second?!
Thanks again,
Richard

Not enough testing!
We didn’t have the best Bonneville racing this year, but we sure met a lot
of really nice people. I put faces on a lot of the people from the internet
forums that I really wanted to meet. Great fun!
There were some very good VW race efforts but the one that should be
commended was the Blackline crew to make such a excellent
performance after such adversity. Well done!
Our little 36hp turbo motor is getting much more difficult to tune on the
road (my uphill road dyno is not long enough). You have to be at full
throttle for at least ¾ mile before the problems start to show up then it’s
quickly too late. What seems to be happening is the needle and seat in
the Weber DCNF turns into a main jet and it literally runs out of fuel in
the bowl. And then goes full lean & burns the pistons in about 3 seconds.
It has great potential, turned the ¼ mile at 88.3mph. the ½ mile at
102.6mph, and pulled up to 5300rpm in 4th gear (111mph) early in the
second ½ mile with 3.88 gears & 26” tall tires at 16psi boost and then
runs out of gas. Well with more testing and better parts we’ll get the right
combination found.
The jetting seems to be ok as long as we have enough fuel. We already
have a large fuel line from the tank to the pump, now it’s time for an
electric fuel pump, pressure regulator, large carb, big n&s, and a large
bowl, etc (maybe Holley 4 barrel?). Rules-wise we can make more or
larger holes in the deck lid but not use stand-offs or scoops. This time it
made a huge backfire in the intake and blew the bellows apart between
the manifold center section and the end castings making a huge air leak
and would not start. Kind-of a blow off valve of sorts that saved the
turbo compressor.

Go to an electric fuel pump with more pressure, and run a boost referencing regulator to increase fuel pressure when boost is present. You'll overcome that pesky needle and seat that way.
Hope to see you next year, I didn't make it out until Saturday so I missed you entirely (bummer!).

Hey Eric, don't let one self absorbed arrogant <delated>'s comments spoil the whole racer pool (I also read the blog on the other site... and will reserve further comment)
You are welcome in my pit at any track, anytime! I am sure that goes for 99.9% of the racers who have ever met you. Better yet, build a car for next year... maybe a Ghia? haha |

If I can achieve my goal of making my drag car street legal, i'll see about throwing in a donor trans in it and going for the 130 club!
Thanks, Tom. Hope to meet you soon! You going to Vegas?
