Paladin with a small turbo its as simple as teaching your self to roll on the gas instead of straight wot. so no problems there. a spin would be driver error in that situation.
if you managed to spin... most likely you will kill the inside tire in a blazing puff of smoke after every corner driving like that. a diff would help in this instance.

My experience is with SCCA sanctioned events, or events ran in a similar manner. The courses we run in our local region keep speeds to the guidelines set in the SCCA rulebook.

Personally, I don't like to see the preception spread that autocross is a sport where you are going to go out there and crash your car, roll it over, run into barriers etc. These are questions I often get when working to introduce others to the sport. Sure people are going to spin their car, but most of time you can put two feet in and shut things down pretty quickly.

Now if your talking about time trials or non-scca events, then that's another spectrum of racing.
no no not time trials.. it is SCCA... just not parking lot auto X... it is basically the same thing on a large scale... depending on where we are at we will set cones up and do it that way but other times we are running on open track. it is a lot of fun... and you are right if all i herd about autoX was how im going to crash than i would never go.. when i started going i had people tell me kinda as a heads up this could happen.. i have never wrecked my self i have come close but never did...

if this is something you have never done before i recommend doing it at least once to get the experience from it... any one can tell you how much fun auto X is...

now back on topic.. i asked this same question two. and with i was told was that in a turn with a turbo when u hit the apex of the turn and are starting to come out of it and you hit the gas if you turbo is small enough it will hit max boost in the turn and can!! cause u to lose control. now i have lost full control of my car before and it never crashed but it scared the shit out of me. so i have been told by others not to go turbo.. now since my car is my daily driver and i do other forms of racing i want the turbo for the pick up i also want the extra power for the long run after some turns to get better time.. i could get the same result with a SC but im just a bigger fan of turbos...lol...

i guess what it all comes down to is do what you feel you can handle...

Paladin ^^ agreed. ive spun the fof severeal times (still learning,doh!!) i dint think i'll be putting r comps on it till i ca nrun a lapping day with my autocross group and not spin out like a fool,lol.

as for what type of power adder. i say turbo. it's the most flexible and can be lowered or raised depending on the size of the track and turns. my gues is 8.5 to 12 lbs. will do it for you.

No if you go from full power, to throttle off in a turn, you will spin, roll the car, no. Were you talking about cars flipping at an autox?

The recipie for flipping a car at an autox is to take a high cg car, stock rear swaybar and springs, slap on some hoosiers that are too wide for the wheel they are mounted on (225s on a 6in wheel) Then go run on concrete, makes sharp unsettling inputs to the car, and then you may be able to flip it, or at least scare the crap out of yourself.

A turbo setup can have a tremendous amount of flexability, and is the way to go for autox.
i think you need to reread what i wrote. i never said it would cause a wreck i said it could.. and most inexperienced drivers have a better chance of losing control of their car in a turn, that some one that has been doing it for some time..

come down to Texas and ill take you out on a big boy track and i can show you better what im talking about... it is hard to get my point across with out a reference i can fiscally show you...

almost any of the drivers that race competitively will tell you to go SC and like i said this is only IMO.

but first thing is first the OP needs to upgrade his suspension. after that i think it would be an ok idea to think about going FI.


i see u race STS. i don't know how long you have been doing autoX, but you do seem know what your talking about.. and i say lets agree to disagree.

blackoutSVT if you do any kind of power adder go with a SC and ill let you know why..

if you have a turbo on your car and you are going in to a turn your building boot up. if you build to much boost and hit your power band in the turn it can cause you to lose control and flip the car...

no with a focus it is unlikely this would happen to you but it could.. i have seen several cars flip over and go in to nasty rolls many times and it is not fun..

no personally i love turbo cars and plan to turbo my SVT some day but im going to set it up with a electric boost controller in the car so i can turn the boost down for running autoX

also think about this with a turbo or a SC it is going to stick you in a class that has cars in it that are built for it.

if i were you i would upgrade your suspension and have fun with it that way but this is only my 2cents.

focusedaddiction ^^I agree turbo a properly sized turbo will make power down low just fine, mine spools almost right away. plus turbos have way more adjustability and easier to turn up the boost if you so desire.
