My RB26DETT 240sx @ KCIR Drag Strip Times

[HxC_Nismo]

well last night i took my car out to kcir with a few freinds and my best time last night was a 12.64 E.T. @110.67 mph with a 1.87 60ft. on bfg drag radials with 16psi on stock turbos. im going to be buying the gizzmo launch interface here in a month or so and going to be uprgrading my turbos and buy snow performance methonal injection kit and I plan to be in the low to mid 11's by next year as long as my finances works with me lol.

[Shocker]

nice. but only 110mph? damn.. my BPU 25 was trapping 109.. shows there isnt much difference between the two.....

[lucky7]

i agree, that sounds really odd. what was the temp like? i would expect my car to trap in the 109, 110 range. bpu 25. nice time though.

i want to get my 2 stage and get some welds with some mickey thompsons before i head to the track. as is i get zero traction in 1st.

[Ramius83]

Well, those times are not that bad, considering it is hot out there. In November, I ran my 11.86 on my stock RB26. But it was about 50ish degrees outside and I was using slicks. What were you "revving" the engine to at the tree, if any at all? With my slicks, I can rev it to 5500 RPMS and drop the clutch and go. That is the trick that I used.

umm im not the smartest person but i've "learned", read, and been taught a LITTLE on math. one class i had was "how can two cars end with the same speed but different times when they drag?" or something like that i believe.

well i think one of my friends hondas did 110 or close to it and only had like a 15.1 so im not sure final speed is a "big" thing to look at, besides aren't we all looking to get there asap when we drag? i care less if my final speed is the same as yours if i still get there sooner

doesn't that final speed have to with acceleration? seems pretty good to me. i would want and be real happy if my stock rb26 240sx ran 12's or less

i think anything in the 12's or lower on a stock car or stock swap is good.

i say congrats dude unless you r disappointed with your time and thanks for putting your time w/setup etc...

trap speed tells all in HP. Reguardless of how ****ty your 60ft time is trap speeds will be around the same ballpark between runs... Your buddy with the 110mph trap and 15.1 ET prolly cut a 3.0+ 60ft which is absolutely horrid.

Final speed is a huge thing. It shows how fast the car actually is in realation to how ****ty or good the pilot is.

troof, trap speed shows you how much you can improve, or at least it does in my case

precisely.

[HxC_Nismo]

well my best trap speed with my car was 111mph at gateway in st.louis, but anyways im running a j30 diff in my car wich is 3.92 gear ration instead of the stock 4.08 gear ratio and i was cutting 1.8 60ft times and i dont have a two step on my car so i just pretty much brake boost off the line at 7 psi and that around 4500 rpm and i was on bfg drag radials. but i was pretty happy with this time, this was the 3rd time i brought my car to the track and every time before this i ran in the low 13's with 2.1 60fts w/o brake boosting off the line. but im going to get the gizzmo launch interface two step and that should help me get out of the whole alot harder. my buddys s13 with stock rb26 ran a 12.8 with his car but theres room for improvement ill get some more track time when i get my two step. oh and i almost forgot im a pretty big guy so thats also a factor lol.

[meet07]

looks like alot of torque caused those numbers.

[Chaos the Xile]

One you get the Gizzmo hooked up you should be in the clear. I Agree 110 is a low trap, I was trapping 114 @13.2, but that all going to change soon!!

[95-S14]

Sounds about right I guess. I ran a 12.8@112 with 1.93 60ft in my car. Its still on the stock twins at 12psi with the J30 rear end on MT ET Streets.

[HxC_Nismo]

well i got my gizzmo launch interface installed last week and got my new clutch installed about 4 days ago and last night i broke my 3rd-4th gear shift fork and i was planning to go to the drag strip today and hopefull run low 12's but not with only 1st,2nd, 5th gear i dont see that happening so im once again stuck with a damm broken trans again.

[Chaos the Xile]

have you looked into any aftermarket dogbox transmission's like OS Giken? or are you gonna reinforce the stock RB25 transmission.

[HxC_Nismo]

where can i get the os giken gear set cause i really want to rebuild my broken trans with that and im in the middle of purchasing another rb25 trans just to get it back on the road cause my transmission in my daily driver just took a crap yesterday and i need to get my 240 back on the road so i can drive it. im parting out my dd integra to make some money to go towards another 240 for a daily (no swap just stock ka) cause i know where to find parts for 240s for cheap anyways lol.

[Chaos the Xile]

shoot me a e-mail or a IM sometime I'll send you all the info. My contact info is in my profile.

[cdorhout]

Dude, you're having the worst luck with transmission's.

The RB25 transmission should be able handle that kind of power no problem. Do you think it's necessary to go to the OS Giken$$$$ gear set?

I suppose it'd be nice, but I wonder how necessary that is.

maybe its because the transmission is dirty? ive seen a porsche that broke the same transmission bad 2x after being completley rebuilt. It turned out that a few pieces of metal shavings had goten between the gears and ruined them. they were smaller than nail clippings!i dunno tho im not a genius in cars especially trannies. maybe they are just really high millage? i wish i could help more!

double post sorry i kno but try contacting somone in jap on here. that way you could get a deal or maybe they can hook you up with a low mileage one for a decent price?i would say madscientis is pretty much auesome so... try and contact him?thats my stating the obvious help

[Dano]

Nice times. You should've come out to our little meet last night

I'd love to see the car sometime

[vashuba311]

HXc nismoI am from st louis and worked down the street from adrenaline. Ii am very interested in getting an rb26 swap. how much did that cost all together, and do you have ac and powesteering?thank you

[HxC_Nismo]

i have p/s but no a/c and i did my own swap and wiring so i didnt pay adrenaline to do my swap i just buy alot of parts from them since i get a discount. but i have a shop about 10 miles north of columbia that i perform swaps at. also back to the transmission issue. when i drained the gear oil out of the rb25 trans there were chunks of metal and also a clip off a synchro or somthing. im tearing the rb25 trans down tommorow and i already have the gear set out of my rb26 awd transmission and im going to transfer all the gear/synchros/ and shift forks over to my rb25 from my rb26 and clean the bellhousing out real good and also the gear set and maybe ill have a bit more luck this time lol cause im pretty much stock for now

[vashuba311]

where is your shop in columbia, thats where i go to school, have to come check it out.

[rb25drag]

Wat were your 1/8 mile trap times? I would think you would be cutting at least a 1.5-1.6 60 foot boosting 7PSI out of the hole. I run a 1.6 60 in the rb25 5 speed No boost off the line. launching at 5800RPM's.

Also your top end speed is going to be lower according to what wheel size you running. The bigger the wheels the slower the MPH.

[HxC_Nismo]

my 1/8 mile time was 8.157 @ 86.23 mph but im also running a 255/50/16 rear tires on z32tt wheels. but im going to the track on the 13th to midnight madness at gateway and im going to try out my new gizzmo launch interface and launch it at 5500rpm on my new mt et street radials. and im hoping to cut a 1.6 60ft.

also my shop is actually 10 miles north of columbia but its a personal shop i just offer swap services etc.

[rb25drag]

Well you should get alot better times, Wat kind of boost are you running topend?

I would think you could get at least a 1.5 60' on drag radials, Especially with boost off the line.

Good luck on your times, Give an update when you go back and run it.

[vashuba311]

just curouis on how much swaps would be.

[fast_s14]

hey Hans, any updates on times from gateway?

[Indolent]

I finally tracked my car for the first time

Stock R33 RB26DETT motor and trans-Intakes-FMIC with steel piping (gets pretty hot)-14/15 psi-Z32 VLSD-Downpipe - 3" exhaust piping-Coilovers-255/40/18 Azenis on TE37's all around (50 pound each rim, pretty damned heavy compared to my GTR32 wheels)

13.02 @ 110.24

R/T .39560' 2.1931/8 8.566MPH 87.57

-Didn't do any brake boosting (scared to move away from getting staged/red lit like my first run lol)-Tires weren't deflated-on my 13 flat i was reving at 5 or almost at 5

Best trap was 112, it was my first time at the track, I'm pretty newb trying to get off the linei went from 13.76 to 13.29 finally then I got the 13.02, so close to 12's! Too bad the day had to end there, I could use some tips/advice next time i go

Hey Hans, your friend with that ran the 12.8 at what psi? tires did he use?

[rb25drag]

All right first off your not going to launch with 50PSI in each tire and catch traction at all, Try getting some MT E:T Drag radials if you wanna run at the track alot. You will get alot better 60' times. Don't run over 15PSI in the drag radials, I personally run 10PSI in mine.

Second set your coilovers extremely soft in the rear if there adjustable it will help keep it from wheel hoping all over the place.

3rd do you have manual or auto trans? on the manual trans the best launch I have has is by feathering the throttle up to about 5500 on launch, I have tried a steady 5000 launch 5800 launch and 6500, on the 6500 I blew both my axles on the line, NOT GOOD, but on a steady launch without a 2 step it seems to bog down off the line more My best 60' on a steady launch has been 1.89, By feathering it I have went 1.67. I think it is loading up with fuel more on a steady launch killing it on the line.

Auto trans you should bring it up as much as possible in RPM on the line without pushing you through the lights. Thats about all you can do.

Believe it or not but with a good hard steady launch you can gain up to 1 sec off your E:T.
