Hoosiers semi slicks on 330D

[speeddemon]

Good day gents
As the topic states...I got a set of hoosiers semi slicks laying at home 17" to fit on my car to try to run better times at killarney.
The problem is that i am scared shitless to use it for fear of buggering my diff or something up:YesNo:
Can someone maybe give me some insight of how safe it is to use that has already tried it on same type of car...330D pre lci

My best so far was 14.5 but i can feel i can do better if i spin less from the line.
power figures a few months ago was 233kw and 590nm....havent done a dyno run again but planning to in Feb.
I'm trying to break into the 13's but cant see it happening on normal street tyres.

i know of someone on the forum - can't remember who - was running semi's on his 330D, extensively modded that run an exceptional time at ODI, in the high 12 iirc. these cars can make well around the 700nm. so i doubt there should be any problems running semi's once in a while

I ran it on mine at ODI with a flimsy gearbox and it was fine

Thanx Karsh...was that 17's as well and wht pressure did you run on it?
On my street tyres i normally drop the pressure to 1.8 bar

I really mean no offence here bud, but with that sort of power figures, you should be well into the 13s.
Both Karsh and Rayzor have run into the 13s with street tyres, and they made much less power than you.

None taken buddy....that 14.5 was done on 203kw and 540nm....havent done a timing event since then...also my mistake all along was turning dtc completely of which resulted in too much wheelspin...I finally figured out now how to launch the car with minimum wheelspin though so i'm waiting to do a timing event at killarney as soon as i can

I wish you all the best! :thumbs:
Should put down a killer time with those power figures

 

[Kish2604]

Put the Hoosiers on... yes they will grip immensely more than your street tyres and yes they can also rip subframe, suspension or differentials to pieces..
However being an auto the power is released into the driveline a little smoother than a manual, if your still concerned then start with higher tyre pressure of 1.5 bar and no track bite and keep dropping the pressure as you get more comfortable with what the driveline can handle.

I would say your car is capable of low to mid 13's once you get the whole thing launching hard, remember the time is won or lost in the first 60ft.

good luck!

I have not run slicks yet but run semis all round on track 18s with 265s on the rear and my car handled it fine .

I make similar power but a bit more torque...I had a previous file on my car and battled for traction from the line..How ever with my new tuner we have boost by gear so allot easier to get off the line with limited wheelspin once you get it dialled in...Try get your sw to lower your boost from 1st till 3rd.

If you don't come rite give RK a shout and he can custom tune something for you and you will gain about 130 nm on the rear :tiptoe::tiptoe::tiptoe:

Howsit Newby46...I hear you...but i prefer to stick to one tuner..so far i am happy with car's performance as is considering the mods i'm running...RK was my first option but they had/have no one in Cape town....car is doing exactly wht you just explained...i used to launch hard but now i just launch half throttle and once she grips i put full throttle....i'm still learning though...but thanx for all the advice guys...I appreciate itraise:

 

[newby46]

No problem buddy good luck

 

[ChrisBrand]

Just remember guys those are Flywheel figures

 

[speeddemon]

Howsit Chris...does it make a difference wether fkw or wkw for the slicks?

 

[newby46]

Those figures are low for flywheel considering up here an lci e90 330d sees 170 wkw and 540 nm stock

I got a pre lci and before sw and dp it only made 163kw (flywheel) and 420nm..also i'm at the coast and u guys are up there (lucky buggers)..lol

shouldnt it make more power at the coast thou?
something i am maybe missing here?

Honestly...I have no idea...I was under the impression that turbo cars make more power and performs better at higher altitude....so i dont really know buddy

 

[ChrisBrand]

Its only to bring across the point that 13s might not be bad considering the power is at the flywheel and not at the wheels.

 

[Rayzor]

Even though it's fly wheel power it's quite decent and more than enough to get you into 13s, practice on your launching and you will be just fine.

Not true

A forced induction car loses power at altitude, it just loses less power compared to an N/A car
