drag slicks and R200 diff

[zthis]

Anybody have any experience running cheater slicks

(ET Streets or BF Goodrich drag radials) on a

stock R200 i'm currently running 12.4s 2.0 60ft

with a 355 chevy, auto, and 24550R14 street tires

i need traction will the drivetrain stand up to

slicks or should i start lookin for rear end parts

now ?

naw, bolt up the slicks and let er rip, odds are halfshaft may go, but ive heard of people running 11s with slicks , auto, and half shafts. mind you, your getting power down, and almost everything starts becoming suspect.

I have an r200 lsd 3.7 / z31 turbo CV's in my 240 with a l28et. Best 60' time is 1.71 with 245/50/16 Nitto drag radials. No bad noises, or broken parts -yet- when launching at 3500-4000.

doug what year z31 did you get the cv axles out of? and if it was an 88 how did you adapt them?

Curtis,

 

Low 12's / High 11's will not destroy an R200. What may potentially break are the half shafts. I've run a handful of 1.60 sixty foot times with 275/50/15 BFG Drag Radials on OEM U-jointed half shafts. The key point to consider is the U-joint angles. If running stock, or lowering springs; the half shafts will be more prone to breaking under heavy loads.

 

A U-joint does not have the "Constant Velocity" that a CV joint has. What this means, is that the further the u-joint is angled, the more velocity differential it experiences. I'm a believer that a U-joint can be stronger than a CV axle. However, keeping the U-joint flat is a problem unto itself.

 

Good luck!

Besides the half shafts, the stub axles, and especially the 240Z ones, become the weak link, not the R200.
