Definitely sounds like it want to rev in your new video. For the N/A run you may want to play with a higher rpm limiter. Would let you rev first gear higher to try to get past some of the second gear bog.
nankang ns2 195 45 15 to simulate a final drive increase to 4.6ish. Tires don't look as far as i thought they would on a 5.5" wide ge8 wheel. Next time i'm definitely going for a 205 50 15.
changed spark plugs, cleaned air filter, fluids checked...still waiting for that nitrous fill.
k20 310 cc injectors installed and working...
trying 3500 to 6700 rpm for nitrous activation. At 3500 rpm that will equal a kick of 132 ft-lbs. (88 up shot x 5252 / 3500 rpm). Will raise that point if too much wheel spin. Shift light activates at 6500 rpm, red line is 6900 rpm. #engineporn
Heres my only 2 runs of the day. Due to late start (rain) and damage to my plugs after the 2nd run....man I need a tune next! All in all, it was a fun day, had an electrical issue that eventually got fixed, met lots of helpful people. Video soon!
14.55 at 95 mph...a new personal best but I let off near the end due to seeing smoke from under the hood. Probably the first damage I did to the plugs.
Second run was a 15.2 at 85...with misfires on 3 cylinders as a result. Now me and the mad scientist have to check out the piston rings I fried. 🤣 Hopefully not, but I was eager to tear this engine apart if so, so no disappointment here. Pumped I got a new PB, but a tune is definitely in order.
Did you take a few degrees of timing out of the tune? I'm betting the Hondata tune is quite a bit hotter than factory to start with so you'd definitely want some timing pulled on nitrous.
What heat range are you running for plugs? I run IK22's regularly, but also have a set of IK24's for when I get around to boosting the thing.
I would think that -4 or -5 on the timing, IK24's gapped to around .40 and a bigger hit of nitrous would get that thing moving even better.

Yup, wish I had time to do some all motor runs first, but it was a good day. You are probably right about the tune and I didn't get a chance to figure out how to reduce timing. I Was up til 2am chasing electrical gremlins last night, and a few today too. I was not overly concerned because i had the trailer incase it broke. I am running 1 step colder NGK copper plugs, as it dissipates heat faster than iridiums, just don't last as long. Running the gap like they come from the factory. Lots of room for improvement, learning as I go...Now not afraid to break things since she's a trailer queen haha.
Since the wind tore off one fender liner, I removed the other one...plus the rest of the ram air duct. Saved 6 lbs hahaha...going to rethink where the air filter gets its air.
Just an update, I'm in the process of parting out my engine bolt ons. Still going back and forth over J series choices while accumulating money for the block.
🤔
Truck and trailer are in the yard. Only thing to do is test the direct port for leaks and even flow. 😁
