Just curious, out of all the FI members here, who is running a manual trans and who is running an auto? I'm going to make this a poll to find out how many of each. I would also like to hear why you think one is better over the other and what your car is primarily set up for. IE: Auto is better for the 1/4 mile because ??? and manual is better for street because ??? Thoughts and opinions?'

Maybe even talk about what converter or clutch you chose for your set up and why. Also post how it's working for you and any recommendations you might have.

I think an auto with turbo makes the most sense. It will spool alot faster and stay spooled inbetween shifts. For a manual i think a sc makes more sense. Since it rpm dependent lag would not be a big issue.

There is a million posts on this.....do a search....FyI auto is better for both cause of the way it loads the turbo and the ease of launching with it........but last week I was doing some from rolls against some turbo-nitrous busa's and I got the power shifting down mint "with the help of a few secret tricks" and walk by them in forth gear.....but the best part was is the turbo never really fell off and the nose never came down. So it's doable to go low nines and well into the eights with a stick, it's just more work and a little scarier, I need a SFI bellhousing, but the launching is some thing I still need to work on....

I apprieciate your input, but the last thing you need to say to me is do a search. I've been on this board for years and don't remember ever seeing a thread like this. Let me clarify: I'm not asking which is better, like all other posts. (What's the best turbo, what will will give me the most power etc.) I am simply asking: Who runs what and why? As an addition, I'm asking what their car is set up for.

BTW I did do a search and found only two threads:
1- Auto or Manual March 07 (not very informative)
2- Auto vs Manual 2004 (joke)

Very interesting thread.

Here is what i have read (am in the process of planning my next stage of upgrades and have considered going FI).

Track-car is an auto for obvious reasons. They are more consistent, and allow you to use a trans break.

Street cars will be dependant on your rwhp goals and the size of your turbo/turbos. For a relatively mild FI setup (talking 500-650rwhp), a manual transmission is fine. The size turbo for that application will spool fast enough to were lag between shifts shouldn't hurt you too bad. When you start getting into bigger rwhp catagories (650-1000+rwhp) th400 (or maybe a 4l80) is the way to go. There is the exception of a twin turbo setup where the lag is not to bad, but it better be right or you will be waiting for boost (experiencing lag) between each shift, thus not maximizing your application.


This comes down to the honest question you have to ask yourself. Do you want
1) a street car that you take to the track for fun (not trying to get deep into the 9s)
or
2) a track car that sees occassional street duty but that is gunning for mid-low 9s (or even 8s).



Anyways, probably enough talk from the NA/N2O guy huh?

Building boost through a stall converter rocks!

(landonew) - Thanks for your input. Again I don't need schooling on this subject. Just looking for who runs what and why. Thought it might be informative for others.

Turbo car should almost always be an auto car.. as said, it works and works damn well on many counts.

My gto was an m6. With the maggie it never hurt me but when I went to a plate kit with a 125 shot It cooked a centerforce d-f and then the spec-3 would get warm and slipp if I ripped 2nd or 3rd and hooked. I'm leanin towards an auto on my next toy. I'm torn between n2o,procharger or turbo.

Its entirely down to personal choice.


Performance cars in Europe all tend to be manual, old people's cars tend to be automatic

The US is obviously different, with the majority being automatic

For straight lines, there is no doubt auto will be faster....just depends what sort of driving experience you want from the car.

This has been beaten to death. Maybe your search was too narrow. Searching "titles only" for "auto" in this forum gives more than 2 threads. Check these out, there's a lot of opinion and bickering, but some good info too:

I run an auto and never go to the track. No doubt do I think it will be more fun to drive a M6, but it is nice feature to have an auto.

what is rpm s highway cruising at 70mph?
im debating between a 3.00 and a 3.25 gear with my th400

At 70mph, I'm at 1700rpm.....which isnt bad, M6

Not exactly sure. Haven't driven my car consistently for a while

My speedo also doesn't work since my cross bar under the dash pushes on the console a bit

I also run a zr1 wheel in back for street duty so the revs aren't super low. With the 28" slick its a little better. 70 is pretty fast. I bet I usually cruise around 60 on the highway.

Once you go Th400 with a turbo car... well, you make fun of all the M6 guys who don't know how good it is.

At 70 MPH I cruise at 2600 rpms in 3rd with a 25.5" tire and 2.75 gears. It's and odd setup compared to most, but it works pretty good for street/strip use.

My car is a M6 and thats what i wanted, i just think its more fun to drive, i make decent power, i know an auto would make more sense. Im not lookin to be the fastest guy around town, i have fun driving my car, its still fast and thats what matters to me.
