Hi guys im going to hit the dragstrip soon for the first time just after a bet of advice and an estimate on what eta to expect. maunual r33 gts25t mods to engine are in sig. suspention setup is completely stock. I will be using hankook ventus k104 tyres 235's on 17" rims.

What tyre pressure should I run with these tyres/rims?

Does the drag strip have a lot more grip then the street? (eg good street road surface.)

Can seems to launch well when you get it right to many revs wheel spin all the way though 1st to lower revs and it bogs down. does not diff hop on the street but will it on the drag strip with stock suspention?

Probably hard to say but with a reasonable driver what 60 foot times should I expect with this setup and what ETA.

:)

Going by your mods, id be looking at a mid 13 and if you hook up real well (say 2.0 60') a low 13 should be on the cards.

I always find the track to have a lot more traction than the street. Its the only time i can open it up in first gear, on the street it always spins.

Good luck

Thanks Robo's low thirteens would be nice. Hopefully I can beet my mate in his stock VX R8 manual clubby.

Start around 25psi and heat them up nicely.  Drop them down if you are struggling for traction, but honestly i didnt find much beneficial with pressures, they just need heat.

So a burnout before a run will be benificial with these tyres? I was under the impression that it would not make any difference as its a road tyre not a slick.

:)

its a must

when i leave my house and my tyres are cold i can spin all the way to theend of 3,rd just about but give them a couple of minutes and 3,rd is out of the question and second becames very hard and im running 255,s 17" advan smokahamas

i to want to take mine down the strip but ive got realy bad wheel hop ever since i changed wheels

cheers chris

if street tyres get out of their efficient operating temperature then you'll be driving on ice...with street tyres they are designed to operate well from cold and do not like to much heat in them....putting too much heat into them will only slow you down IMHO

They will be cold lining up for your run so putting a little heat into them shouldn't hurt.

i changed pressures from 38psi down to 20 and it made no difference, (255/40/17)

most low profile tyres have very stiff sidewalls such as mine, so even if u drop the pressures it wont do much.

Thanks can anyone using hankook k104s confirm this did it make a difference with the tyres left down? how stiff are the sidewalls?

    • Major thread necro but how bad of a job is it to DIY? Looking at it online it looks like if you reuse your ring and pinion as long as those are in good condition it should be fine to just pull the axles/front cover and replace the diff that way? Or should I be replacing everything and doing preload measurements/gear mesh testing like the factory service manual mentions for the rear diff?
    • in my list I had the R33 GTR as the best Skyline. Infact I had all GTR's (33>34=32), the NSX, the GTO, the 300ZX, the 180SX, the S15 better than the FD RX7. I had the MR2 and the A80 as 'just' better. I also think the DC5R Integra looks better but this is an 01 onwards car. I also think the FC>FD. It's almost like aesthetics are individual! The elements @GTSBoy likes about the FD and dislikes about the 180 are inverse in my eyes. I hate the rear end of the FD and it's weird tail lights that are bulbous and remind me of early hyundai excels. They are not striking, nor iconic, nor retro cool. The GTO has supercar proportions. I maintain these look much better in person (like the NSX) especially with nice wheels and suspension which is mandatory for all cars pretty much. Some (or all) of these you have to see in person to appreciate. You can't write a car off until you see one in the flesh IMO. Like most people we probably just like/dislike cars which represent certain eras of design or design styles in general. I also think the 60's Jag E type looks HORRIBLE, literally disgusting, and the 2000GT is nothing to write home about. FWIW I don't think the Dodge Viper Gen1's have aged very well either. You can probably see where I rate bubbly coupes like the FD. I know we're straying now but the C4 and C5 absolutely murder the Viper in the looks department as time goes on, for my eyes. Wouldn't surprise me if people who love the FD, also love the MX5, Dodge Viper, Jag E Type, etc etc.
    • I used to hate R31s, and any of the other Nissans that led up to it, and any of the Toyotas with similar styling, because of the boxiness. They were, and remain, childish, simplistic, and generally awful. I appreciate R31s a lot more now, but only the JDM 2 door. The ADM 4 door (and any other 4 door, even if they are unique compared to our local one) can eat a bowl of dicks. The Aussie R31 is also forever tarnished by their association with stereotypical bong clutching Aussie R31 owners of the 90s and early 2000s. I think the Nissans of the 70s (other than 120Y/180B/200B) are far superior looking to the 80s cars. The 240K era Skylines are boss. The same is broadly true of Toyotas. Hondas don't ever register in my thinking, from any era. Mitsus are all horrid shitboxen in any era, and so also don't register. Subarus are always awful, ditto. Daihatsus and Suzukis also don't generally register. They are all invisible. I think the SW20 MR2 looks fiddly. The 3000GT/GTO is like that but way worse. Too many silly plastic barnacles and fiddly gimmicks ruined what could have been a really nice base shape. Kinda-sorta looks like a big heavy ST165 Celica coupe (and I'm not sure if that's a good thing or a bad thing). I think the 180SX is dreadfully bland. It's not bad looking. But it has no excitement to it at all. It's just a liftback coupe thing with no interest in its lines, and bad graphical elements (ie wide expanses of taillight plastic on the rear garnish). The S13 Silvia is a little better - getting closer to R32 shapes. But still....bland. S14? Nope. Don't love it. S15...a little better. Probably a lot better, actually. Benefits from not being like a shrunk in the wash R34 (where the S13 was a shrunk in the wash R32 and the S14 looked like a Pulsar or something else from the stable on Nissan mid 90s horrors). The Z32 was hot as f**k when it came out but hasn't aged as well as the A80. Keep in mind that I think the R33 is the most disgusting looking thing - and out of all the previous cars mentioned is objectively closest to my precious R32. It's just....real bad, almost everywhere you look. And that is down to the majority of what was designed in the 90s being shit. All Nissans from that era look like shit. Most other brands ditto. In that context, the FD absolutely stands out as being by far the best looking car, for reasons already discussed. Going behind the aesthetics, the suspension alone makes it better than almost any other car.  
    • If they just called it the "Mazda Tiffany", it would have been spot on.
    • Yup but for me its the HR ! Cut my teeth on the old holden 6s in the day ! And here's me thinking in the day it was also the 300ZX and the Mitsubishi GT3000 ! All, as well had good lines, but always seemed to need finishing off, style wise.
