Last year i was about 220 - 250 whp and i was running 20" slicks..
i hit 13.3@ 102 with 1.8 60' .... now i was scrapping almost 5th..
This year i will be close to 400 whp.. and when i upgrade my mani and turbo i should be at 450 next year...
what size slicks should i be running 22 or 24 ? and how wide?

 

anyone ??

 

go ahead with a 24" x8.5x13.
that would be a good size for 400+ hp
