What RPM do you launch at?

[umsports]

Hey Guys,

Well, I broke the R200 diff launching at about 5000 RPM last night in my RB26 240SX, So, I don't plan on future attempts to probably launch over 3000-3500...

What do you all launch at?

[whateverjames]

31 x 100 RPM

[SRBURG13]

Yeah, about 3000 - 3500.

[AlligatorBling]

depends... but on average 3 to 4k, lets you break out in a good portion of the torqe power ban for the ka ::edit, but you dont have a ka do you...:: lol

[24Zero]

3300 is always good

[Tygma]

does your car still make that nasty rattle?

[lbcklik1486]

Maybe next time instead of launching at 5K, try slipping the clutch a bit. Starting at 3K might be too low for the rb. The KA is relatively torquey down low so that's why it's ok to dump it from pretty low rpm.

[MakotoS13]

my advice is to buy a quaife diff and do whatever runs the best time :)

can you say: "warranteed under normal AND racing conditions"?

[ONEBAD240]

What do you mean by nasty rattle :naughtyd:

[NinjaGaiden]

depends on what kind of tires you have.

Kumho 712s.... I dropped from 2500rpm and it spun the rears without wheel hop.


Bridgestone Potenzas S02s... I dropped from 3000 rpms and car shook like crazy... damn wheel hop! Can't wait to get my sub frame spacers tomorrow.

i just installed my clutch and i cant even launch my car at 3000 rpm... it doesnt go anywhere... but i dont have any suspension yet....

I hate you! <-- HATE! ALL OVER!

Nah...

I want an RB26 damn you to hell... Broke youre R200 Dif... What a bragger. :)

You might just want to get diff rear while youre at it... With all the power of a RB26T-TT? you dont need the 4.083... you should look at the 3.9 or 3.8...

[silviadriftr]

7500 rpm on slicks. breaking tranny is a problem. I am now on my fifth trans. Doing a z32 trans for street and powerglide for the track.

[Touring240]

4600 rpm on 225/50/15 bfg g force drag radials with vlsd
I slip it a little off the line

[Zemus]

4500 on 245/50/15s, somtimes 5k KA, with super slipping of clutch, launchs like a AWD car haha, no tire spin

[andrave]

13,000 RPM
I want to go higher cause it bogs but I have the factory bottom end, so I try and keep it under 15,000 rpm.

[ryan hagen]

with v-lsd, and 255's i ll give it 4000-5000 little spin, then alot of hook up

[sykikchimp]

Slipping the clutch is the best way to get good times, and get the least damage.

[XxJaPxOxNeEs23xX]

dr1ft32. u jsut installed your clutch and your already spinning the tires with the clutch!?!?!??! did you buy another clutch set already?

[nissandr1ft]

Considering your setup this prob. doesnt help. But I always launched around 4k and sliipped the clutch on 195's.

[wootwoot]

i still have not been able to find a good description of slipping the clutch. the way i imagine doing it, you would heat the disc and flywheel extremly badly. but just dropping the clutch aint to good either. anyone want to give a decent explination?

[brianglawson]

yeah explain "slipping the clutch" please
