is it true that MH Drag Slicks was nothing to MT Drag Slicks??

im using MH 23x15x9 on my 300hp civic eg (b20 pro 2 cam)... and i disapointed because my power doesnt go to the ground properly... it spining everywhere from 1st until 3rd gear with that tyre... (if it spinning only on 1st gear maybe it was from my suspension or driving style that sucks, but its still spining everywhere until 3rd gear)
anyway i've done a lot of suspension tuning for this car, i stiffen the rear suspension, mild in front (24 kg rear, 12kg front) so the center of gravity would be bounced back to the front end when the chassis get some impact from the launch.
i've traction bar, Quaife LSD, etc.

im sad, my 30hp power gain only reduce the time 0.2 sec, because the power was never putted to the ground properly.. i cannot floor maximumly this car everytime i shift from 1to2 and 2to3

some one said that MH slicks that comes to my country (indonesia) was having bad compound, and he recomended that MT drag slicks was far better than it.. and i plan to use 24.5 because the track in my country was extremelly sucks !! bad asphalt.!
and i need bigger tyre so the car would finish @ 9K in 4rth gear (now with 23" it forced me to shift to 5th gear arround 20meter before the finished line)

so i plan to change my tyre to MT...

please recomend me.... need advice a.s.a.p

 

How many psi are you running in the tire? Tubes? Rim screws? What's your camber and toe like?

 

10psi... toe zero, chamber -0.5 degree, so when the car lifted on launch it would be 0 chamber...

wich one bro? MT/MH???
sighh...

 

We run the MH's with great success...

 

is there any other compound in MH Racemaster type?? maybe i have the 2nd class compound (not trying discredit or what.. its a pure question bro)
thanks !

Are you getting the tires hott enough? Also try a little less air pressure then 10psi.

 

originally did you not have enough power to be at redline in fourth gear? shifting into 5th kills mph and ET. a taller tire or higher redline might help. as far as i know there is only one tire compound no matter what country you live in you should get the same tire.

what type of 60 foots are you seeing? 10psi might be too much pressure in the tire.

 

that 15" rim isent helping either

 

You have a lot of power. Have you ever thought about running a 24.5 MT? I ran them with less power and went 1.60-1.62 consistantly.

 

I have always used M&H's with good results but I do notice that alot of the big boys use MT's and they seem to get much stickier, maybe I will try them one day.

you already answered your own question to the problem buddy. Your tire is too small in the first place. you need the 24.5 MH. and as far as tire compound, you cant blame a tire because your spinning. there are other issues you are encountering. Lets say you're making 500hp and using a 22" tire, you cant blame compound because you cannot hook up. youre just not on the right combination...

im sure its hot ennough.. burnout on second gear arround 3-4 second...

yes, i ussually shifted @ 9.2k ... the powerband feels drop above that rpm
hhmmm... so no other compound type eh......
my 60 is disapointed... 2.0sec..
how much tyre pressure you recomend me? 8?

yes, i should run 13inch rims for the next tyre... wider side wall = better traction

yes, ive try 24.5.. but it was old tyre, and the thread wear was so close to end.. so maybe the compound was already bad... it still have 2.0 60ft.. but better finished rpm in 4th gear (arround 9.1-9.2K)

allmotorhatch, did you run MT or MH?

sory2.. im not blamming MH.. yes i know... im sure i should run bigger tyre.. but i just want to make sure about the differences compound issue that my friends tell me...
anyway thanks a lot will...

That is you answer.
Bad asphalt probably no tractoion compound just like overhere.

 

MT is a much better tire, go to a local sfwd race and you shall see.

 

bring the tire pressure down to where the tires wrinkle (7-8 psi) and do a large burnout. Also What rpm are you launching at? Are you using a 2 step limiter? If so what Boost are you leaving the line at. All of this info will affect your traction

 

I changed from M&H to M/T and the car is .1 slower on 60' almost every pass. I have not been very happy with them at all. Not to mention that the sidewalls leak air around where the letters are on the side. I will by M&H next time.

 

Hi jt-sport; The sizes you have is our M&H 8.5/23-15 and for the HP you have you should step up to the M&H 8.5/24.5-15. Our compound is the HB-11 and it's the best.

M&H

Danny, based on your times vs. hp, it's safe to say you do not have the car dialed in for traction to begin with, so your tire comparisons as far as traction is concerned don't hold much ground. Get the car dialed in running the numbers it should be and then compare the tires, i think you'll find why most of the fast guys run MT's...

 

I ran both M&H and MT. I had better results with the MT.

 

ok, at first i want to say sorry, i open this thread not to discredit or what... i just want to get some oppinion from the master arround here..

im sorry john @ MH and Will Exospeed... actually i've ennough satisfied with MH since the year of 2002...
but maybe yes, the 23 tyre was not right for my combination. and the 24.5 was too old so i might have wear problem with that 24.5

--------------
anyway i want to discuss about gearing that was connected with tyre diameter....

it was started from : https://honda-tech.com/zerothread?id=2065977
but no one ever comes there...

here it is the question bellow here :

<TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote, originally posted by jt-sport &raquo;</TD></TR><TR><TD CLASS="quote">now im using ats gear 3rd,4th and 5th close gear with 4.4 fd..
tyre was 23nch (MH).. power was 300hp crank hp... arround 250whp S.A.E correction
finished on 4th gear on 9.5k. (sometimes it forced me to slice it to the 5th gear arround 20 meter before finish line)

friend of mine that has already run 11.3 sec said that :
"it better with four gear to eat the strip, so we couldnt lose time by shifting"

but when i saw leslie, eric (old coupe), etc, they finished on 5 gear.

next i would go with 2.2L setup (target gain more 15-20 more hp with pro 3 cam, now i run pro 2)
so i plan change my gearing setup... :

1. if i want optimum 4th gear maybe i would run 4.0.
2. if i want 5th gear maybe i would stick with 4.4 fd

-which one should i choose???? 4 gearing or 5 gearing???

-and would it be better if i change the 1st gear to 2.9 or 2.8???? now im still thinking that it (longer 1st gear) doesnt really important, because when it goes to 2nd gear i dont feel any drop in rpm.... but friend of mince said that i would need longer gear when i go with 2.2L, so the car would launch better (more minimum wheel spin)
need advice about this 'longer 1st gear' also...

plss. and thanks</TD></TR></TABLE>

last year went 17.7 with a 24.5x15 it can be done it is all in the setup. and as stated above, most of the fast guys will tell you the m/t is better than the m and h.

i run the m and h though he hee. 3rd gear burnouts tonight w00t!

Just want to add, that this is a generalization and does not reflect every tire and combination possible out there. There are 1000s of Hp and engine combinations from 100hp to 1000hp, and each setup will require different tire size. some setup their cars with a certain tire, others will do it with another brand.
A racer will just have to try out and see what is best for his setup. what works for someone may not work for someone else.

 

It's not magic, there's not 1 tire that will work on one persons car and won't on another. Certain sizes will be better for different applications, but it's not like a different setup will not work with a tire.

The first hand results i've seen over and over is that MT tires last 2-3 times as long as M&H. When they're both new, traction is very similar, after 6-8 passes the M&H's are worn out and the MT's still have 10-15 good passes left in them.

ive got about 25+ passes at the track on my 22" m&h's and they are only about halfway worn out.

it has nothing to do with the actual wear holes, its more of a heat cycle issue
