As I told Marc Thomas when I wanted some new shocks, "I want what George has." Unfortunately, whatever Marc gave me, that was not what I got. George's car is a wonder - stock springs with konis and rock stable at extremely high speed.

Congrats to you and George for 198+. I'm positive 200+ will happen next season.

 

Congrats to your super fast run! I hope you can figure out what happened, and that it's minor.

 

Congrats on almost 200...199/200 you should of just received it by default...

 

Great Job George,

You were so close, I hope the mechanical problem is a small one. I'm sure you will archive 200+ mph at the B100 next year. Looking forward to seeing the video

 

great story, thanks for sharing it!

 

George,
You're MAF voltage is just about maxed out - I assume you're running a standard MAF. I would highly suggest that over the winter you get a MAF restrictor from Tim (or a slightly smaller one if you already have one) and re-tune the car with that so you have enough MAF to get you to 200+! Once the MAF gets maxed out, your AFR is likely to lean out.

 

George
Damm so close...198-199....with a touch of tuning this winter and maybe a super MAF you will get there..... Ideally it would be great to get a full sharktune at the elevation you run at...it will not be ideal here...but who cares about that right?

 

Thanks all. I appreciate your positive comments.

Andrew,

I am running Tim's restrictor, and do max out (6.1+ v) at sea level. So far I haven't run lean on
top, but it is an area that I'll have to look at more closely. I think I'll have to upgrade my in-tank
fuel pump, ARRFR (Aerometer 13105), oil breather system, intercooler system, and engine monitoring,
assuming I can get this motor back together soon...

 

OK, I finished the first video. This is the 1st speed trap. I had to use my laptop, since
my home desktop died a few weeks ago when it tried to upgrade to SP3 of Windows XP.
I did try a new thing with the LM-1 Log. What do you think?

The video does bounce around a little. I think we forgot to use the EIS...

 

Motor sounds very sweet. In hindsight, it looks like you could have carried even more speed through the sweeper before the trap. 170 is about 25 MPH faster than I have ever gone through it, but you appear to have had room for 180+. The car is on rails! The superimposed log adds a lot of suspense as the speed indicator slowly rises. And to think with your new 2.2 rear, you had 800 RPM to spare. Oh, I figured out the top indicator is boost, right?

 

You're right about being able to go faster. Since the course notes were set
up for averaging 160 mph, the turns are not posted at the limits. As I've moved
up in speed classes, I add speed to the corners. In this case, the notes said
155 (from last year), and we went through at 170. Next year, I'll up it to 175
or more. The same would be true with the turn before the 2nd speed trap.
I should be able to carry 170+ through that turn.

And yes, the top indicator is boost. It topped out at 10.6 psi on this run, though I
have seen 12.8 psi in 3rd gear at this altitude.

 

That is all the V1-T has, it can't spin any faster. No boost to be gained there without going to the V7-Ysi which will do 15-16psi at these altitudes.

 

Damm 10.6psi at 5700rpm 198mph....in probably 100+ heat at 6000ft....damm.....

I do like the data logger readout..... that looks sweet.....

Now upgrading the SC to the V-7Ysi at 15+ psi..... that might make close to 600whp?

 

Ballpark of 620-630rwhp, I haven't dyno'd it yet.

 

The motor internals are fine. It wasn't the LH brain, but we had some interesting results with brain swaps (that can be explained) that initially mislead us and had me scratching my head. Eventually we did find the major problem. Fortunately, it's not serious. George will have pictures and the full story at 11. Sustaining 10 PSI boost for 83 miles at a stretch will expose any weaknesses in the system. In this instance, it took about 60 miles.
