VintageRice Posted December 22, 2012 Report Share Posted December 22, 2012 Dangit you suckers quoted me before I got a decent pic up....DANGIT! Here! lol Quote Link to comment
VintageRice Posted December 22, 2012 Report Share Posted December 22, 2012 I predict that KA24E will have about 140 HP (120 rwhp). Are you talking about mine? Thats probably about right. After gaining flow with my carbs I probably gained back what I lost in not having a proper efi tune. Who knows. Specifications Stock Ka24eBore × Stroke: 89.0 × 96.0 mm Max power: 140 hp (105 kW) @ 5600 rpm Max torque: 152 lb·ft (206 Nm) @ 4400 rpm Valve Configuration: SOHC, 12 valves Compression ratio: 8.6:1 (9.1:1 for early 1989 240SX) Quote Link to comment
datzenmike Posted December 22, 2012 Report Share Posted December 22, 2012 So what your sayin is your building a carb'd KA?! I want build thread. P.S. I want to get my ka dynoed just to make sure I didn't loose HP lol but seriously I would like to see what it does, just hate that the dynos are innacurate like people have been sayin. Dynos are close enough. It's an indication of power and doesn't necessarily make you faster than someone with less power, assuming you both used the same dyno. Nor does it indicate how well the car will run. What it can tell you is if you are going in the right direction when tuning or adding a performance part. Many changes are subtle and not really noticeable like a small broad torque increase. On the other hand a dyno can be the ultimate arbiter of who has the most. Quote Link to comment

ggzilla Posted December 23, 2012 Report Share Posted December 23, 2012 Alright, 275 HP from the Nissan DOHC Turbo at 16 pounds boost! Now that's better than all this talk. 12 second quarters -- that is supercar territory! Quote Link to comment
72240z Posted December 23, 2012 Report Share Posted December 23, 2012 275 is a typo right? lol275hp at 16lbs would be pretty sad since a s15 makes 250hp @ 7psi. Should be more like 330-375 at over 1barThe 1/4 time is off to me too unless it was a bad launch or something. A heavier 240sx runs under 12 sec with a sr @ 16lbs. I would think A lighter 510 would be low 11's at well over 300hp. Quote Link to comment
ggzilla Posted December 23, 2012 Report Share Posted December 23, 2012 Yes 275 is transcription error. It is 269 hp per the dyno sheet Quote Link to comment
72240z Posted December 23, 2012 Report Share Posted December 23, 2012 Seems really low, there are a ton of dynos and vids of sr20's at 16lb. They are all well over 300hp. Not knocking the car or saying its not a blast or any shit worth arguing. Just that the numbers dont seem very good to me at all. Quote Link to comment
ggzilla Posted December 23, 2012 Report Share Posted December 23, 2012 It matches up. The 1/4 mile MPH (not the time) is perhaps the best way to tell the HP. It only takes 265HP or so to do 114 mph in the quarter with a 2300 pound car. Quote Link to comment
510T Posted December 23, 2012 Report Share Posted December 23, 2012 Yeah definitely not a pro at the lights and the 175 tires were spinning through 2nd hence the crappy 60ft. That was my second and final time out to the 1/4 for the year (and ever). I have replaced my clutch and tires but will not be back to the 1/4 until I upgrade axles. I think low 12's are possible with more seat time. Maybe get into the 11's if I got some drag tires. I feel the 269hp will improve with upgraded injectors, bigger muffler, and the installation / tuning of my AEM Series2 EMS. Goal is 325-350 on this turbo. It is a blast to drive at the current spec and still returns 30+mpg on the highway. Quote Link to comment
72240z Posted December 23, 2012 Report Share Posted December 23, 2012 I feel you missed my point ggzilla but its really not imp. bababooey good attitude. I'm sure you will reach that goal with that plan and break 12 sec easily too. It must have felt good to spank that supra lol Quote Link to comment
ggzilla Posted December 23, 2012 Report Share Posted December 23, 2012 Very possible you could do 11s with suspension/tire change. There's .7 seconds lost in your 0-60 time. The time is not a close indicator of HP like the MPH is. Quote Link to comment
510T Posted December 23, 2012 Report Share Posted December 23, 2012 I love the bench racing btw that's why i fed the fire :thumbup: Quote Link to comment
510T Posted December 23, 2012 Report Share Posted December 23, 2012 Yes best time yet and I beat the old man in the auto supra lol Quote Link to comment
72240z Posted December 23, 2012 Report Share Posted December 23, 2012 Ya I bet 11' wth a good launch, especially if you evenc ome close to your hp goal. THEN you'll be at proper supercar levels. 12-13sec is like 80s super car levels lol. The new Aventador runs the 1/4 in 10.5Bet the old guy never saw it coming haha Quote Link to comment
Dawa Posted December 23, 2012 Report Share Posted December 23, 2012 lol 175s, gross Quote Link to comment
510T Posted December 23, 2012 Report Share Posted December 23, 2012 Not really trying to go faster than 11.5 though, I do not want to install any kind of cage. 175's are gross haha. The old man was a friend of a friend. He was from supraforums and knew what was up. I was stoked. The next 2 and final runs I spun the clutch shifting into 3rd and times suffered.

Dat Lurka Posted December 23, 2012 Report Share Posted December 23, 2012 Yeah 110mph wont kill you but better get a cage for 130. 1 Quote Link to comment
