Default how could i gain MPH

well guys i been hearing that MPH is what matters for the street, is that right.?? ok now if i was to put some 373s in my car would it be quicker in the streets or slower.?? i know itll drop MPH in the quarter mile since it finishes faster but i need to know what works better for the streets, i also heard the faster you go thru your gears the better itll do in the streets too, and i know with some 373s it will rev up faster, can someone plz answer me all these questions, thanks for your time and help, just trying to get as much as i can in the streets

Actually I think this is an interesting topic for the street racing section.


A guy I know has a 408 wit 4.30s and a 26" tire. It definitely would haul *** at the track, but for roll racing, it doesn't work. (Actually it wouldn't work at the track either since 4th tops out at ~120.)

Here's a video of him vs my buddy's H/C LS1 (3.73s with 27" tire). 408 makes 508rwhp, WS6 made 446, both cars were close in weight at the time and had a passenger each.

ROLL STARTS AT 2:44

http://www.youtube.com/watch?v=ULv2r2QuPkQ


He should have pulled pretty easy, but because he's shifting so often it hurts him. He's going to a 28" tire now so that should help out a lot.


Some people may argue, but I think less (gear) is more on the street (for roll racing anyways). 3.73 with a 26" tire, 3.90 with a 27" tire, or 4.10 with a 28" tire would be perfect street combos for our cars in my opinion.

This is what "racers lounge" is for.

Street kills is for kills.

Only thing killed here is the english language.

Best most for an auto, no matter 2, 3, 4, 5, 6 speed, is always a converter. Properly picked, it'll get you right into the meat of your powerband, so gears aren't as big for an (stalled) auto car and much as a stick car. I have been told that gears do help tighten up a converter though.

Case in point- My buddy just got done building his LS3 for his 99 SS. When it was a cam only car, it flashed to 5200 on the hit. Now, it flashes to 5700 on the hit. Car has 3.23s and rolls out just fine. Can't wait to see what it flashes to on the nitrous. 6000+??

[The converter is a Yank SS4000 btw.)

I disagree. The title of the section is "street racing" and kills stories, and this is street racing related. Up to the mods though...

You getting soft in your old age these days??

LOL...I always went by "street racing & kills" means ONLY things related to actual street races. There are plenty of other areas for a topic like this (especially ones where you'd get much less ridicule).

I guess I am getting soft, at the ripe old age of 22...23 next month.

Like I said, if it needs to be moved or locked, so be it. But I see it as fitting in this section, it's kind of like a BS thread. Now if more like this start popping up then away.

That's why those new 5.0s run VERY hard on the street. 3.73s and 5th being the 1:1 instead of 4th really work well together. Always in the powerband it seems.

Lemons will come in here and say MPH means nothing in a street race, but I'd say yes and no. Yes, it can give you an idea of if 2 cars will be somewhat close, but 2 cars trapping around the same will run different. A 128 car and a 130 car isn't as close of a race as you would think, but a 120 and a 125 might sometimes end up closer than you expect...so it really can't be used as a failproof method.

I don't know how you can measure if a stalled car "lose" MPH on the street, but at the track, it can sap up some mph but it's big gains are seen in ET. That said, stalled auto cars run extremely hard in street (roll) races from what I've experienced.

Hahaha...well the age part was a joke. And the above comment is perfect for a BS section bash extravaganza, so I'm a bit interested now.
