@DRAGRCR - hey Ron, thoughts on the wear of MT ET Street R? How about ETR vs Hoosier QTP? I need to stick with the DOT tires to run in my street classes.
2 things. I used Diablosport tuner in my 2016 Hellcat. The 91 octane tune would open the throttle in about .3 seconds with me light switching the throttle. I went -20% on the throttle and it then opened the throttle in about 1.3 seconds. I went from spinning on all 5 passes one Thursday to hooking on all 5 passes the next thursday. Honestly my 60 foot was only off about .02 from what I expected. Even if the throttle takes 1.3 seconds to fully open, it's still opening some and making power way before that.
I do not have any resent exposure to the Hoosier QTP. I ran them years ago on my 71 Demon and they worked well. But they were 29" tall on a 15" rim.
Right now I likely would run the Mickey Thompson ET STREET R. It's a little perplexing but I have a good friend that just switched from the 29.5X10.5R17 Hoosier DBR to the Mickey Thompson 315/50R17 on his LOW 9 second PCP Demon.............And he went from having to be careful and likely going to spin anyways, at irwindale, to hooking EVERY time. In fact he is about 20 passes in and has not spun once. He said he is flooring the throttle every time and it hooks.
Not 100% sure but I just read an article in National Dragster about Race tires and they said they do sometimes make running changes to the compound (without releasing a new modle). The 315/50 ET STREET R never hooked like that on my Stock Power Demon, for comparisin. There were definately times it would spin.
If I were you and I had the cash I would run the 315/50 on a BS WIn Lite (has .200 less back space than the Weld and Forgestar etc.) and get out the hammer.
Here is another thing I just saw that I want to mention just because we are talking tires. I saw a Stock Demon rear wheel on a Narrow Body, but, it had a 305/45R18 ET STREET R on it. Honestly most of the Pics you see the wheel has a 315 on it and it sticks out and looks bad. But with the 305's on there it did not look that bad. AND, as an added bonus, that tire likes to be stretched and will work better.
