question about aluminum ds

blackjack21 · Aug 12, 2008

what do you guys/gals recommend for an aluminum ds......site,name?

if you are at stock height, do you have to change the pinion angle?

Spydershafts are suggested a lot. You can read more here:

Spydershaft; had mine for over a year now... problem free

Spydershaft, Coast driveshafts, Driveshaft Shop, The Axle Exchange, etc...there are quite a few. Just gotta do good research.

I've had the spydershaft for almost a year with no problems. It comes with a pinioin flange.

Is anyone using a spydershaft with a FI engine? I've been told to stay away from aluminum unless it's at least 4" for supercharged cars. I've read that 4" shafts can cause clearance issues with lowered cars. I was thinking about going to an aluminum driveshaft but my future plans for FI made me decide to hold off.

Does anyone here have the real scoop on these issues?

I have the Coast Driveline shaft, & it's rated to 500 hp. they also sell one rated for 600 hp, so if you plan to build less than 600 hp they have a shaft for you.

The Spydershaft has been tested repeatedly at the track with slicks and 500 RWHP.

Shaftmasters is good too and very affordable.

Powerhouse 4" aluminum shaft.
Bolted in in 45 minutes. If you are not lowered there is no need to change pinion angle. I tested mine to 170 MPH without vibration and have run it for two years at the dragstrip without issue.

Runnin the spydershaft for a year now, with the car lowered on prokit springs, a hurst shifter, bmr adjustable UCA, and the bmr front driveshaft loop. I have zero clearance issues. Ran the car for months without the UCA and it was fine that way as well..

white07gt-cs · Aug 19, 2008

Thanks for all the informed feedback. It sounds like my concerns were not well founded.

blackjack21 · Aug 24, 2008

is it necessary to have the safety loops????? just my dd car

JPAC · Aug 25, 2008

I run a coast ds. I have the prokit springs and have had clearance issues only at the track. I was running ET street slicks and launching at 5000. Cured by adding a little more neg pinion angle and massaging the tunnel with a hammer and grinder.

JPAC · Aug 25, 2008

Oh, and it is a good idea to throw a loop on while you have it apart. Just in case you ever hit the strip with slicks. I put a BMR unit on mine for $99.

What kind of gains are people seeing with the Spydershaft?

mhanksii · Sep 1, 2008

Is there more or less gain with a F/I setup? I was thinking about a driveshaft but not sure if that would be better than some gears or maybe both. Any input/adivce?

No one?

BJ1000RR · Sep 5, 2008

You will see more gains with a F/I setup, but maybe 2 tenths on an otherwise stock car.

I personally like the stock 355 gear, because you dont have to shift out of third in the 1/4.

ranger04 · Sep 5, 2008

Not shifting out of 3rd isn't really a good thing. Gears are a torque multiplier, they get you to the sweet spot faster. Only using 3 gears seems like a lazy sorta run and your not getting the full potential of your engine. If your pounding 6,200 rpm's through 4 gears in the 1/4, your humping. I maybe looking at this all wrong, but with my 4:30's, it screams, the power stays on tap. It pulls hard through 4 gears. It's a lot quicker than it was with the 3:31's. Like I say, I might be looking at this all wrong, but with 3:55's your scrubing off some speed it seems to me.
