Which transmission type do you run with the Guard diff Eddie? (930, G50 or turbo G50-50/52?)

Tnx,
Walter

Sorry to bug you with the same question Eddie but have you ever considered a C4 driveline? I've just always wondered why not, I do like 2wd more but surely it would help you get the power down?

Bello's managed to turn low 9's in a 911.....I doubt there's a whole lot out there that he hasn't thought of already.

Thanks! Makes sense too of course to run the strongest factory trans .

Not sure how the extra front wheel drive would help a wheelieing (sp?) car? With that power there is really barely traction up top either I suspect. Even factory 4WD cars that are purely set-up for drag racing (EVO's, Impreza's) remove the front wheel drive and convert to 2WD as it doesn;t help and only makes the car heavier.

^^^What he said... (although I was ignorant to the EVO, SubY info) I'll say this, for what it's worth: I had the luxury of driving a 964 C-4 based RUF with a CTR engine a few times...On LOW boost (.6) bar or so, It absolutely roasted the front tires going into third gear...Although I feel it was probably only one tire, as the front diff is an open differential, If there were a Torsen type diff available, well, you would probably just roast BOTH tires...

(for the record, the electronics were taken out of the loop as far as controlling torque split, it was done with a hydraulic pressure regulator manually right next to the boost knob, the psi on the gauge was an indication of the torque split...the car was built for Pikes Peak)

tested on a friend car c4 where 3.3 turbo did not like it at all. gear ratios all wrong cost you 7000 in gears to change them all. the rear wheel drive works fine testing tomorrow at the track.

Thanks for the replies re 4wd, very interesting,

I just see the way 993TTs, 996TTs and 997TTs get off the line, stock ones beat the same model GT2s with more power. 9ff's fastest car is 4wd, quicker than their more powerful GT3 version, anyway, just askin....

Anyway, looking forward to seeing the Skyline drag! Awesome!

"he talks a lot of crap talk" LOL!

You're comparing apples to oranges imo: mostly stock cars and street orientated cars to a fully modified car with drag compound tires. 4WD is safer to sell to the general audience when a car has lots and lots of power.

I saw 9ff's 900+ hp car a few years ago doing a 10.25 1/4 mile and he spun his R-rated tires all the way. Talked to him for a while waiting together in the line (at Bitburg, germany). Even his soft circuit orientated semi-slicks at really low tire pressure were not right for a really fast drag pass.
With the right rubber, the weight transfer on a 'perfect' drag race start is always maximally to the rear axle. Tire choice is paramount.
With conventional tires (GT2), the same drag race start looses traction quickly and your better off with 4WD.
99% of the people are better off with 4WD and both 9ff and Porsche want to sell cars (and not held liable for people killing themselves, bad for business), not win drag races...

Eddy is that rare 1% I suppose

That old heavy Skyline won;t know what hit him LOL!

Congratulations, Eddie .. 161 is hauling butt. I know Matt appreciates mention of the GT LSD solving your handling and diff breakage problem. I'd heard about the previous string of bad luck ..

BTW, the Skinne Bug also uses a G50/50, but with the full GT dogbox conversion (links below). I haven't heard from them in a couple years, so I suppose "no news is good news".

Our Maui parts tester was pretty fast in its day (9.36 @ 146, but just VW stuff):

Wow! This is wheel-hp right?
I remember an older dynorun of 1200hp from you but that may have been crank-hp?

Always good to gain lower rpm torque What typ/model were the previous turbo's?
