Was on the xr6T forum today. They were comparing the new F6 with the w427. There speculating the F6 will have around 600nm of torque and about 320-330kw, compared to the w427 with 370kw and 650nm? torque. the F6 will probably cost 1/2 the price and may actually keep up with the w427.

Now I think the R35 doesnt weigh all that much less than the F6 and w427. It has less torque than both and its power figure sits in the middle of both.

Would it be reasonable to say that the F6 or the w427 could out accelerate the R35 if they were rolling and did not loose traction?

Im not too keen on anything with 7L but the F6 with launch control could be a ball tearer.

There was a comparison on the LS1 forums and the outcome of that discussion was that the R35 is quicker to 100 and down the quarter than it by a fair whack. So in short, in a straight line at least, no those cars couldn't keep up.

Well hard to say, I dont really know what both of the local offerings will hit the scales at. I know the GTR is heavy but it does make as much as the 427...I would still tip the Skyline to be a bit quicker.I believe one of the latest motor magazines compares some 427 holden against BMW and Merc.This car was tested making 400 kw ( according to the magazine )..it was quicker than both, but it only ran a 12.8 according to their tests..I am not sure this is the same car as HSV is building ( Maybe an aftermarket job ) but a 12.8 ..? I was expecting a low 12 or high 11 ...Dont really know much about what Ford is building. Potential is there to be fast..who knows

There's probably enough literature and automotive tests on w427 and the R35 (japanese version) to make a punt on who'd come out quicker. But then again, it's not really a fair comparison as the R35 has two less doors and is built ground up as a competitor to the Porsche 911.

i would have thought this would be due to traction. i have a feeling if they were rolling and had no traction loss these cars would keep up.

No way will the F6 come out with 320+kw, try 300...and no they won't compete with the GT-R.

The W427 and Typhoon will both be using either manuals or torque converting autos. Even if all else was equal, they wouldn't keep up on that alone.

The 997 Turbo has the same power and less weight than the GT-R (and both are AWD with fat, soft, rubber), but as it doesn't have the instantaneous gearchanges the cars are line ball in a straight line. The two cars' manuals are nowhere near as smooth and easy to use as the Porsche's, so they'll be slower. If you got the autos, they're only marginally quicker than the manual cars.

Unfortunately, not all else is equal. The GT-R's aerodynamics are far better than the two sedans', so once you get up to speed the GT-R will still dominate.

Only if you're talking about an high-gear roll start at low speeds and the R35 is off-boost will the 7.0L Holden have a chance of winning.

I would have to say the GTR, namely

horsepower / weight similar?

traction superior

gearbox changes faster

launch control

For the Ford to be quicker,

- it needs to match the traction (i.e. not one of those dodgy systems where the car puts on the brakes to stop wheel spin in acceleration. So without AWD, and assuming a good TCS then it would need the right tyres to make up for this

- gearbox either needs as quick a gearchange or no change at all i.e. 1st gear all the way to 100km/hr

launch control or an ace driver to make up for the balance of revs/wheelspin without smokin' it or bogging down

So it might be possible with equivalent power/weight and an 'ace' driver to keep up / maybe win but then the GTR will have repeatable performance.

A guy I worked with modded his XR6T so it had 355hp at the rears and it used to freak him out, the traction control would cut in and slow the car down enough to make him think he was going to get t-boned! it shows that a RWD TCS is not really a match for an AWD

Also if you haven't seen this article from Edmunds, then it is not too bad a read - especially for Nissan fans

A rolling start certainly doesnt take traction out of the equation

Lets think about that, based on my post that we're responding directly to Amir's question in the first post of this thread?

(Emphasis added by me, spelling mistake is by him)

Would you care to revise your statement, given the context of his question?

      SR20 to cefiro

      Given you already have the engine cross member to match and likely gearbox mount to. The SR20 has a head start on the RB in this case. They handle GREAT with an SR20, lots of fun.   One I did back in the day

      have no doubt and wanted too trust me and may regret later not necessarily worried about weight (would be 8 kg ish total) it was more the $$ to do it properly is about $6 - $7K in hardwear need long 310mm stroke jacks etc - plus install and call me whatever im not doing it myself even if wanted too cant weld etc  - thats $10K installed vs fraction of that cost while Ive spent some money on this POS I actually really dont like doing so unless its got a large chance to make me go faster 馃榿 hey in still carting this things around on a 15 yr old rusted open trailer so I can spend on racing not buy a new trailer to look better the manual jacks Ive had done are heavy and take space but are transportable and usable anywhere - taking or organizing even compressed air let alone nitrogen which is more whats needed coming from Perth to Winton or Sydney or the like honestly just adds to my brain headaches/ hurts of organisation also ha 15 mins job will get down to 2 - 5 min job vs 1 min job for airjacks - all tradeoffs I spose

      Purely out of curiosity, how do you know all this @dbm7? Do you work with automatic gearboxes professionally? This goes way way way beyond "I've had an automatic Skyline once and did some mucking around"

      I'll just reiterate that it's best to do all the wiring diagnostics, before even thinking about buying replacement solenoids ~ that is, be absolutely sure the solenoid is bad.....ie; bad connector(s), rodents chewed through a wire, etc etc. If you don't so this, you can fork out all the money for solenoids, only to find something else is wrong (this'll make you cry if you pull the valvebody only to find a broken wire is at fault... ...some more glue on the solenoid packs -- this is the RE5R01A shift solenoid assembly.... ...these are all shift solenoids ~ ostensibly they're the same as the shift solenoids from the 4-speed auto.... ...this is the RE4R01A solenoid set... ...with these, you have 3 shift solenoids attached to the plate, and the separate solenoid is the EPC solenoid (line pressure control) -- with both designs, the TC lockup clutch solenoid (also PWM so they could slide the clutch shut), is located on the lower valvebody half.... ...(story time)...back in the 90's, it was a common fault that the EPC solenoid (or TC-lock solenoid) would fail, but Nissan only sold them as part of the assembly (think ~$350 at the time) ~ thing was, Isuzu also used these boxes in light commercials, and you could buy the PWM solenoid as a separate part, so it was possible to buy/use that solenoid (around $65), and make it fit (remove the circlip, fit to old plate and deal with wiring)...making it a more cost effective repair. I've not seen the RE5R01A shift solenoid assembly, but with the 4-speed RE4R01A it was possible to hack/fit a single shift solenoid onto an other working set, using a donor solenoid from another set with failed EPC....(by rights the whole set should be replaced), but it ends up being a question of how much life is left in the box itself ; sometimes it's a viable repair to fix one solenoid, just to get another 100k of road miles out of it before it needs first overhaul...other times the box is that old/worn, you're as well doing first overhaul and replacing the solenoids and starting fresh... What Nissan did here with the 5-speed, was relocate the EPC solenoid to the lower valvebody (next to the TC lockup solenoid), and stuck the direct-drive clutch solenoid (for the extra gear) where the EPC solenoid used to be on the 4-speed....I can only imagine they did this for serviceability ; the PWM solenoids are most likely to fail, and it's a doddle to drop the pan and change these out (as opposed to dropping the valvebody itself to get at a top mounted EPC)... ...also keep in mind, that some BMW 3/5 series & Mazda (and maybe some Ford/Mazda rebadges, not sure), also used the RE5R01A box under a different name/part number...not saying parts availability is any better, but sometimes it helps to know this when it comes to NOS floating about in the EU....

      FWIW, air jacks are actually pretty light and simple to add, they are just 4 hydraulic cylinders (often at the main cage A and C pillar points) and an externally accessible airline  - they make quick work a breeze
