hitting the drag strip 1st timer

[Munna]

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.

you will beat him no worries

Any idea on what tyre pressure I should try with the hankooks on 17" rims? I was thinking of starting at around 25psi.

[Robo's]

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.

[Robo's]

Road tyre, slick doesnt matter, they are rubber they all like heat. Notice how bad your tyres are before they warm up and when they heat up. I notice a fair difference.

Makes sence Robo's I had just read differently in other threads.

Yeah if I start at around 16:59:47 on a Wednesday you might be right

with road tyres though u odn't need a huge smokeshow to warm them up, but none the less it looks good so do it

[blackr32gtst]

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

Thanks guys looks like a burnout and 25psi in the tyres will be the go.

[morlock]

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.

[benm]

Just drop the clutch enough so that it skims the first layer of crap (plus the burnout water) off ur tyres, u dont need to perform a big smoke show.... all that will do is hirt your wallet.

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?

[siksII]

if u want to find out, just go down to the petrol station and let them down to about 20 and see what happens, thats what i did.
