Slick sizes

Hello,

I'm from the UK and currently only run road tyres. I've found the 5-10mph i want on my ET, Should be over 125mph now. (don't know how slicks will effect this) So i should be able to run a pretty good time with more traction 2.0 60foots on the road tyres.

Anyway,

I was thinking a 23" x 8" m and h drag slick. Just a few questions.

Where should I get them from, remember i'd need shipping to the UK. And what size?

Should i got 8 or 9" wide?
Should i go for 23" or 24 to give me some more top end in the future, (i'll probably never sleeve this block but would like to hit 500.

This is the main question, what will be the difference between a 13" and 15" wheel, I know the 13" will give me a better "cushion" for the tranny and possibly more traction, but what really is the difference in time? 0.1 on the 60 foot? More?

Many thanks for your help, I know this is probably the wrong section, but most the drag guys in here can answer my question directly.

:bigok:

Right ok, I thought as much, a 4" sidewall isn't very big for a slick is it.

I'm currently running a Z6 tranny but it's broke (again) So i'm going to swap it. I think we get the same trannys as you over here but I was looking for something longer. (to run road tyres) as I have to shift to 5th.

I will obviously have more top end on the slicks so might stick with the Z6 tranny.

Do you know the RPM i'd need to hit 130? That'd be a nice target IMO. Especially as my traps will probably fall a couple of MPH from what there at now.

Whats the difference between M&H drag slicks and "cheater" slicks?

How long are the ratio's do you know?

Also, i've just looked on that site,

It says my 225 50 15's have are 23.86 and i'm hitting the limiter in 4th at 7200rpm's. I suppose if i rev it to 7700 that'll be ok.

you should wait to see what kind of power you will be making before you get slicks. if you get to big they will slow you down!
im at around 300whp and plan on gettin 22X8/13
