I run a 285/35 zr18 nitto 555 on the street. I wont hook if i nail it but if i easy into it, it will spin some but not much and eventually hook. Lower gears in an A4 are a esaier on the tranny, cause it doesn't take much to move ur car. Your rear end will eventually go, but till then save some money on the side.

Whoops again and this is the best explaination I have seen, sorry it is from a non-sponsor site.
Selection of the right stall speed for your vehicle should be matched to the engines peak torque; engines torque curve, and vehicle weight. In general, the desired stall speed would be 500-700 RPM below the engine RPM at peak torque. The speed allows a margin for application of the torque reserve on takeoff.

When selecting stall speed without having an accurate and precise engine peak torque rating, it is better to conservatively estimate the engine torque than it is to over estimate it. If you over estimate the torque output, the resulting stall speed will be lower than intended and is likely to make the vehicle slow off the line, increasing your ET.

lol I don't know if you rember me I think I raced you a while back....

Anyways I have a 4000 with 2.4str in my car now if you want to go for a ride when I put it back on the road next week.

 

that be awesome, i have the stall but i havent gotten it installed yet, maybe that will get me motivated...

i'm not sure if i remember who ya are, whats ur your look like?

 

What is the str mean?

 

Cams that large will demand a high stall speed. I run an MS3 and first installed it in front of my current 3500 stall speed converter. Big mis-match. Performance improved a bit with a 4,000 stall speed converter.

I vote 4,000 but make sure it can handle nitrous if you do that in the future. My current converter is a Yank SS4000. High enough to make the MS3 happy and I can spray it.


Search button?

Stall Torque Ratio. Search this sight and search engines for more in depth info. Or wait for someone to type it all out.

Basically the higher the STR the harder it will hit, and the tighter it will drive on the street. It will also, in general, handle nitrous a little better.

 

I have a white 98 formula....

 

ah, you Formula_ls1 from previous boards...?

 

Yep

You may not want to use the trex and a 4000 stall...its kinda small for that cam.

 

With a shift extention of 5200+ RPM, you're saying thats too small?

 

LOL at bring back a 2 year old thread.....by posting on the poll

 

It's a zombie, run away!!!
