I wanna keep my 2.73 rear and I want to sometime run high 11's with my combo. Currently @ 12.9 @ 108 with my minimal mods. What i'm shooting for is a TCI 3500/2.5 or Yank 3600-3800. I will do cam shortly thereafter and am looking at the Futral F11 and F13. I'll be buying HP Tuners here in the near future so I'll be able to get all of the tuning straight. Does anything think that the 3500+ with a F11 of F12 will be a great daily driver, 2.73, and all around track car? I'm not worried about the looseness, I've been in a 3800 2.73 geared car. Thanks guys!

With a 2.73 your going to need a ton more converter to go fast with a big cam like that.

My 02 daily driver in sig runs consistant 11.7s. I have a Yank SS3600, Absolute 5.3 S2 heads, MTI Stealth cam 220/220-5.81/5.81-115lsa and 2.73s. Full weight no suspension mods except LCAs, it sounds fairly stock and is great around town.

yea, I've heard of 3800-4000 to go with it, but i was looking towards TCI because of price. I already got a 24K cooler. Thats some nice times Caveman. A LS6 intake will be on my list too. I didnt think the F11 or F13 were big on todays standards. I had a friend with a 3.23/ PT4000/G5X3 run 11.97 on his one and only run at the track. That was on a minor tune also. I'm thinking 3800 is optimal, but which cams would be the best for that setup. Should i look towards reverse split cams at all?

can I ask why you want to keep the 2.73 rear ?

Likely daily-drivability. That's why I'm keeping my 2.73s but stalling it too.

yup.. good gas mileage on the highway its really nice going 70 at 1800rpm on the highway. Also the 2.73's are easier to get good 60' times at the track with a stall on radials. I'm keeping my 2.73's and putting a 3200-3800 stall converter into mine after I get headers, y-pipe, and HP tuners on board.

if you want some gas mileage, why not try some 2.56s . That's going to be one hell of a stall. I wonder if you're car would still creep off the line with a 3800rpm Stall TC.

1800 at 70?? What the crap?? I'm at about 2200-2300 when I'm going 70. I thought I had 2.73s. That's what the code on my door says.

yeah mine sits 1700-1800rpm at 70mph. I had 3.73's in my a4 v6 and it was at around 2500-2600rpm at 70mph. I bet you have 3.42's in your car or your converter is very loose. i'm still running the stock converter.

This link has a nice gear/speed/rpm calc. Its pretty acurate too.

I would lean to the SSF3500 & get rid of the steel drive shaft (you don't need the extra rotating weight). I bought a used stock M6 shaft for $100. Not sure about the cam's I do have a rev split TR227 & like it, But there's so many good cam's out there. Do alot of research.

being a daily driver I'd like to keep gas mileage anywhere that i could. I want to run a fast time on a 2.73 rear and it can happen. I bought a 3.42 rear carrier and it was too $$ just to get it all setup and everything. As said above. I'll be able to get better launches with the 2.73's and it'll be less stress on the rear and tires.

Not once you reach the point that your gears bog your car down when you hook because first gear is so tall. Been there, done that, 4.11s make for much fun

why dont you go with something like 3.23's then? i mean if you want the full potential of what your building, then your gonna have to break down and forget about gas mileage!

I'd suggest a slightly smaller cam or slightly bigger converter, but there's
otherwise nothing wrong with what you want to do. See sig for all motor times, and the car IS a piece of cake to make run fast on the street on DRs

I'll put in a 3.73 gear in the spring and show you the difference is about
-0.2 ET / 2 MPH on a stalled auto....

nice times also Crazy Bob. The F11 228/230 .595/.585 on a 114, is probably as small as i want to go, and 4000 stall would be the highest with 3500 being the smallest converter. Gears would be in my future, but that would be around the cost of a converter and I'd rather to converter over gears.

Why worry about the cam? You can get there Stock Internal (with 2.73's)

You would have to go a little bigger on the stall but it can be done. I think you will be fine with those converters. I had a Yank SS3600 for a little while. Loved it on the street and dropped a solid .4 at the strip. Might have given me more if I had the ET Streets then.

To the guys that say you will bog off the line with 2.73's......how many actually had a stall with those gears? Don't get me wrong, 3.73's and others will give you gains......but you will be just fine where you are. Not to mention road trips.

i had 2.73's, ssf 3500. got sick of it though- they are just too long for daily driving imho. i would also spin the hell out of my nitto's if they were not really hot and it was above 70* out. bog? no ******* way. not with the verter..

i think you will get sick of the longer gears also. i don't NEED to be going as fast as those gears would allow for cruising on the highway. my driving record already has 2 97/98mph in a 55mph zone on it, i won't be able to get out of another. i also didn't see any good gas milage because the converter would always unlock if you try to accelerate because of how low the rpms were. the only gas milage you would see is strictly highway, like when staying at 55mph or above because you can accelerate with the verter locked.

from a dead dig (like in a race) i think a nice sized cam would be fine w/ the 2.73's, but from any type of rolling punch it may suck. that would take alot of the fun out of driving the car around.
