Testing tomorrow and Sunday - 300 shot

Post  psfracer on November 1st 2013, 7:53 pm

Testing tomorrow and Sunday at Famoso. Going to see if the changes I made will allow me to 60' in the 1.25s consistently. Going for some 8.50s in the 1/4 as well.

If Saturday goes as planned, I am going to try a 300 shot on Sunday and do some 1/8th mile passes. Hopefully high 5.3Xs. After looking at the plugs, some full 1/4 mile passes after that. My best on the 200 has been a 5.56.

This motor has been running great for 2 1/2 years, time to lean on it some.

I've got 3 go-pros and my bro on the camcorder, so I should get some good vids.

Testing for SCSN9 in Vegas on 11/14-11/17.

If all goes well you should run your number. I've been there with my junk and you have MUCH more than me

Yeah definitely going just to the 1/8th first.   If time allows I am going to try a 250 first on Saturday afternoon.  I run a 200 now on 22 degrees of timing with VP NO2 120 fuel--but a very conservative 2 spread on fuel/nitrous. 5 3/4 lbs fuel pressure.

I still can't believe how much it picked up after you did the heads. 9.41 to a 9.16.

I bet it would pick up more if I put a bigger carb on it to.

Oh yeah, silly me.

I will PM you about the carb and get your thoughts on what I need. I didn't realize you sold carbs.

1] Big compression
2] Fast burn chamber
3] 10 head bolts

I think you should evaluate your piston to head distance & consider a cam change when you go to 300 shot and above.

Be carefull with the timing also.

Just ran a 8.579 @ 158.78 with a 1.272 60' and an 1/8th of 5.495@ 127.15 mph.

250 shot, still conservative with a 4 spread, 5 3/4 psi, 20 degrees timing.

So no trips needed to the Hero parts trailer yesterday, and I always say that is a good thing.
Ok, so here is the deal:

The Saturday runs were just my "baseline" runs as I wanted to see the difference my changes made on the following day, Sunday. So on Sat I ran two 8.75s @ 156 mph.

Sunday: I changed the tune up as follows: OLD tune up was 26 N20 jet, 24 Fuel Jet, 7 psi fuel, 22 degrees timing. Was too rich, leaned it up a bit to a 28 N20 Jet, same 24 fuel jet, reduced fuel psi to 6 psi on the N20 regulator, and backed off the timing to 20 degrees. Car responded with the 8.579 @ 158.78 with a 1.272 60' time.

Still showing a little rich. Stayed with same 28 N20 jet, changed fuel jet to 22, kept fuel pressure at 6psi, timing 19 degrees. I could tell the car liked that even more, but unfortunately it blew the tires off, so its making some power.

I also ran a 8.66 @ 157 but my bottle pressure was way low on that pass as there was a delay on the track and I was in the staging lanes a long time.

Anyway--I am going to stick with the 250 shot and continue to refine the tune, as I am noticing the engine responding to minor changes in a big way. Also, the car will be hitting the limiter through the stripe at 160, so perhaps a little taller tire or a slight gear change is in order. In any case not worried about it right now as my cage is only good to 8.50 anyway, and I think by continuing to refine the tune I will reach 8.50.

Video. There is always video. Video of my best pass:

Thanks!  I really think this thing has a high 5.3X in it for the 1/8th.  I am running out of gear for the 1/4, I don't see me going any higher then 160 on the mph though in the cars current configuration.
