My best time was a 13.2, but my 60' was a 2.3 (terrible) on shitty tires. My best trap speed was 111.5mph. For the boost reading, ambient temperature will also affect what is being read. Difference between winter and summer can be 1.5psi difference. With the SC, it's always a good thing if you can get the boost number to go down without changing pulleys, it means there is less resistance for air going into the engine and there will be more power and less heat.

I'm know researching this and 13.2 seems great especially on shitty tires lol. Did you get a alot of wheel spin going down the track?

I'm​ at 9psi with my setup running k24a2 CP + 3" BP. Car feels strong and after my last .Kal I loaded, I think I'm done ready to make a run lol. IATs are my worry since I'm not aftercooled. I'm spraying ~8gph of boost juice to help, but temps still climb.

I didn't make it. My brother was trying to get me to come up, but the wife and kids were sick.

There is a good bit of wheel spin, even with the BBG having 1st turned down a good bit. If you are at 8GPH and temps still rise, you should start stepping up the nozzle and see what happens. I'm about to go to 18GPH from 14, since mine is still on the rise as well.

I have a 1000cc nozzle (~15.85gph) that I could try. It just seems like a lot to jet as I'm spinning the blower at 15.5k max. I guess I can give it a try and see.

EDIT: So, I went home for lunch and installed the 1000cc nozzle. I updated my .kal to spray (minimum): 3500 rpm, 4psi, 75% throttle, 12mph. I'm pulling -400 fuel unit starting at 3500 and progressively increase to -600 at 7600. I'm advancing timing 1* to 6* progressively up to 7600. I'll report back results.

Nice. Are you using 2 tabs for the w/m? I've set it up that way, as described in the past by others, to overcome the delay between the need and the actual fluid being delivered. The first tab has everything set to enage sooner, but with no changes to fuel or ignition, while the second one makes all the subtraction of fuel and additional ignition. Also, you may end up pulling a good bit of fuel out of there. I couldn't really tell what it was doing with the factory o2 sensor until I could see it get closer to 12:1AF then back it down. At first it was so rich the car was much slower. Those settings are with my current 14GPH nozzle and 750 injectors. I've got my lean cut set for leaner than 12.4:1 over 300ms @3+psi to cut and even dropping from 6th to 3rd and hitting it there is never a lean condition.

Yessir, running 2 step. No1 sets pump at 3000rpm, 2psi, 65% throttle and no values adjusted. No2 sets minimum values mentioned above.

You are pulling quite a bit of fuel! From my logs, AFR seems to still be fine based on pulling around what swatson pulled when he first started his w/m journey years back. I'm not aftercooled, so Im sure this plays a factor. Do you still run factory O2 sensor? I'm interested to see why my numbers seem ok even though I'm spraying ~15 gph of 50/50 meth. One would think I should pull more fuel based on yours, but my pic shows -1% fuel adjust in the high speed fuel comp table during the datalog.

With 1000cc nozzle, I definitely felt a kick. No bog, but got 2 knocks between 4000 -4500 rpm. Stopped for gas and dialed back IGN a bit in No2. Attached is my current fuel & IGN compensation on No2. Car is pulling hard where I'm losing traction now, no knock, and temps are not spiking in the 170s* :fyea:

I'm still using an OEM Primary for tuning. The factory o2 sensor bottoms out around 11.5:1, so it may take a some experimenting to ensure you are pulling enough fuel. I'd pick an rpm range or 2 to pull more fuel from and see what it does. If it's running way to rich that can play into the knock as well. That only says 1% because of the lack of visibility by that oxygen sensor, I wouldn't only go by that. Also, remember the kpro is pulling fuel/ignition from 8 cells at any given time. 4 from the current cam angle, and 4 from the adjacent and blending all those numbers based on what it's closest to in terms of map/rpm.

Are you still on the 25 degree VTC? Can you send me a pic of the base ignition you've got at your max cam angle on the high cam? And your cam angles if you don't mind.

Ahhhh, good to know! I was very conservative in pulling fuel, so I'll pull more and see what it does!

Excellent, I can all but guarantee you need to pull a good bit more, which will make you even more power since it won't be pig rich. I'd guess you are closer to 10:1 right now if you had an aftermarket wideband hooked up. What RPM is your Vtec set to? I'm kinda surprised it doesn't bog at 3500rpm for you, but that's a good thing anyway.

Yes, still on 25* VTC. Wish I would have modded the VTC to 45 degrees lol. See attached base high speed IGN. This is based on my last dyno tune and I tried updating w/o meth. Any value I advanced in col 11-13, I would see knock, so I reverted back to it.

I'm tuning on stock O2 lol, so u could be right. VTEC set to 3200 rpm lower and 5200 upper. Zero bog when it starts spraying... I thought it was going to IMHO.

Updated to pull -800 units from 3500 to -1200 at 7600. Will see how it pans out when I leave work

Went and showed with cauqazn and his friends there. All supercharged :bow:
:awwyea:

Recognize 3... Also that CL :eek:. What is he running??? Does he even have a hood?

Blue car almost never takes its top off :happyg:
People love the CL he steals the glory ha. He has a hood cut to fit the blower but didn't run it :fyea:

Lol, ya I don't recognize the blue RSX. That blower looks huge on top of the j series. I've seen supercharged 3G TLs here, but never seen the blower mounted on top like that. Probably twin-screw :dontknow:

Mine VTC is set between 25 to 35 and at higher RPM after 6000RPM, it comes back down to 25. I didn't leave mine at 30 degrees or more as I didn't notice any more power. Have not dynoed so won't know until I see the torque map.

I have 2 stage Meth setup also. Tab 1/Nitrous 1 pulled all the fuel and add all the ignition and second tab just engagement of nozzle only. This way I can keep an eye on how much fuel is being pulled.

everytime it sprayed, AF is never leaner than 11.8 and my base ignition under boost on column 11 and 12 never get past 15 or 16 degrees.

Ah, good to know! Highest VTC reading I've seen was 26* during datalog a WOT pull. For your 2 step, you run dual nozzles as well, correct? So first tab is larger nozzle to get some performance improvement, and 2nd tab is the smaller nozzle for additional spray for cooling?

I changed my target lambda from 11.5 to 11.6, but I'll try 11.8. I think I'm uber rich when I spray based on factory O2 not able to read below 11.5.

Another random question... Since I converted back to an SRI, I want to run a vstack and filter. Right now I'm looking at the blox 3" vstack + 6" K&N filter to replace my eBay filter lol. Anyone else run this filter setup or something similar?
