Hey guys I want to get some of your opinions about high hp and big rims. Heres why, Im getting ready to do anoth project car and I want it to be close to my old car but with a few new upgraded parts. My old car was a b16 turbo i made 450whp and I had 15 inch wheels and BFG Drag radials all around And I loved the car it was real fast real responsive. Now of course with that much hp your gonna have traction issues but i had big beefy drag radials on. I didnt have any boost by gear so it made 450 in all gears. And I had tractions problems but over all for the hp it hooked up pretty good. Now One of the only things on that car that was stock were the brakes and I soon realized I could go to such a high top speed and I could get there so fast but there was nothing to slow me down at that speed. So for my next project I wanted to get a set of wilwood big break kit so I could actually stop and I would like to make around the same amount of hp so I was thinking if I got 17 inch wheels I could get a big brake kit and if I got boost by gear that would allow me to run around 400 whp and have decent traction. Im wrighting this hope to hear from people who have big brakes and high hp to see if theres anything I can do to gain traction. I would like to find out of this would work or with rims that big if it would just spin no matter what I did

 

I made 375 whp at 17psi (t3/t4 57 trim, .63 A/R) on my b16a turbo in a eg hatchback, I ran boost by gear via NLR AMS-500. The car would hold 15 psi in first from a roll with 205/45/17 Nitto Neogen tires at 30 psi no problem on warm days. Now if you ****** gears or drop the clutch it would burn the tires but if drove right it would hook!

 

the tire spinning would have more to do with compound than anything. (not including launch, where sidewall does come into play).

 

Its definatly going to be more of a rubber compound issue but when trying to launch the tiny sidewalls of the 17" tire are useless and traction will be non-exsistant

i personally like 15" for the street, yeah you dont get the baller look but you get alot more traction. Boost by gear will help you gain traction just dialing it in is what it will take

 

My B16 made 607whp and 390tq and it hooks 530whp in 3rd and the full 607 in 4th. Using 15 Gsr blades with 205/45 Nitto 555R drag radial.

 

Ok so it's possible than. I just figured with that amount of hp and speed it's nice to know you can stop if necessary. Now since rubber compound is what will matter most what do you guys reccomend

 

you're limited, in 205 40 17 you only have two choices. falken 615s or nitto nt01's the 615 lasts about 12k miles and the nt01 about 6-10k, both are warm weather tires only

 

keep what u have. get better blank rotors and use better pads and you'll be fine.

:edit: Thats IF you have the EX/SI rotors.. If you dont, then upgrade to those. then you'll be fine

 

my first hand experience says Nitto Neogens and the price cant be beat!

 

Im running 205/50/15's Falker ZE-912's which is an all season performance tire. i hook just fine on 400whp in a dc2 chassis. it will amost take full boost in 3rd gear and 4th gear it hooks 100%

 

hooking fine would be traction in 1st

that you do not have

 

Well if i wanted to swap out WG springs to a lower pressure and run a 4 port mac solenoid then i could hook in 1st gear as well, it doesnt concern me to much because im not street racing where i would need traction on the roads in 1st gear

 

These are always a great choice and easy on the bank and can use smaller rim. http://www.spoon.jp/eng/details.php?...md=civic&cid=6
Also if you are running rear drum brakes swap those out for rear disc from Teg, Si, Del Sol Si/Vtec that will help out a lot.

 

Ya I'm gonna swap my rear drums to disc from an SI and thanks for the site i'll check it out. Do you have any first hand experience ? whats your set-up
