New personal best. Spinning through 1st gear, 60 ft time could be better with traction. Too bad I forgot to get the gf to record video Haha. This was my 3rd and last run of the day, first pass was 10.76 @ 131.8 . 23-24 psi boost, t04r single turbo. My tune was a little too rich, I made some recent changes and didn't get to tune before today, so I could have made a little more power. I hope to do even better next week.

 

Congrats ... nice work!
with that trap speed it will be easy hitting the low 10's ...

 

Nice! Are you using the stock trans and diff?

 

Thanks. I am using a stock jdm tranny I put in recently, I shredded the 3rd gear in my old stock tranny when I was doing a bunch of 3rd gear pulls tuning it. And its a fc LSD and stock axles.

 

You just keep on rolling, impressive Tom!

 

What kind of power did u put down on the dyno

 

528 rwhp https://www.rx7club.com/time-slips-dyno-121/528-rwhp-428-ft-lbs-24-psi-pump-gas-wi-973231/

 

very nice Tom, keep making us proud!

 

What are your highest knock readings at what boost and rpm?

 

thats a great 60' in my eyes considering i do much worse. what tires are you using?

 

Thanks. Ya it is a decent 60 ft time, not bad, if I can get It to hook better it will be lower. Tire pressure was set to 13psi before that run. My best is 1.48 with the stock turbos. MT ET Streets 26x10.5x16. Crane 2 step.

I will upload my datalogit files later tonight.

 

My highest knock reading was 19 in 3rd gear at 7267rpm 26343pim (about 23.5psi), highest in 4th gear was 15, mostly between 3-11.

My datalogit maps and datalog files are attached. I was also logging AFR and fuel pressure.

 

Wow that is quite impressive! Congrats! Must be a heck of a car to drive.

 

Great work. Get some video!

 

Wow nice power im hoping to get over 500 once i get bigger injectors

 

Thanks guys. Ya its fun to drive, It's just a lot of tire spin above 15 psi boost. I'll get video next time. I'm still trying to get rid of a little boost flutter in 4th gear at 24 psi, I can see it on the boost gauge and hopefully that's why my fuel pressure flutters a little. I have a 14 psi wastegate spring in there now which was a nice improvement over the 10 psi spring, but I still need a stiffer spring so I Just ordered a 1.2 bar spring, that should work better for high boost but then I can't run low boost anymore, oh well.

This was done with the headlights up too, because of my custom cold air intake I have been leaving the passenger side headlight installed in the up position for night street tuning. I wonder if I would have went faster if they were not up lol. I have brackets to mount just my headlight cover in the down position.

 

damn thats fast.

 

Probably good for some trap, but probably not much time.
We demand videos!

 

bump for video

 

It's supposed to rain and snow tomorrow, this sucks

10.51 @ 133.2 mph 1.52 60ft spinning and pedaled it. first run was 10.54 @ 133.53

 

10.51 timeslip. 3rd and last run today was 10.56 .

 

So I found out today that my tire pressure gauge is off and was reading about 3 psi lower than the real pressure, so when I lowered them down to 11 psi trying to get traction, they really still had 14 psi in them. No wonder I been spinning so much in first gear. I should be cutting low 1.4s or 1.3s I think with traction, will try again next Saturday. Also will be installing a Hyperion in tank fuel surge cover so I shouldn't need to run 3/4 to a full tank of gas.

 

Glad to see that same engine still running. Traps in the 1/8th are awesome man, what boost were these runs on?

 

23-24 psi. Runs great. thanks
