Hey guys, I'm curious of thoughts or experiences running turbo setups on the autocross tracks? I run my 67 c10 daily, and at the track every couple weeks. It has an ls3 with a mild cam and longtubes. Trans is a t56. I have 2 precision 6266 .82 turbos sitting around from a stalled project and was thinking about putting them on the c10. I'm so worried I'll be disappointed with lag on the short courses. Anybody have any thoughts. Will they come alive quicker than I think? Or should i just cam up some more and throw some heads on? Let me know your thouvhts.Thanks guys!
What exactly do you mean by a short course ? Just how short ?
What is your gearing like for whatever speeds you might see ?
What sort of power are you after, need...or can put to the ground ?
What is the expected rpm range you'd be using ?
Will they come alive quicker than you think ? I don't know, how quick do you think they will come alive ?
And is that last question asking whether you should just add cam/heads and stay n/a, vs a twin turbo build with turbos offering a potential 1000+ ?
There would appear to be some major goal differences between the two.
So again...more detail on your goals, expectations and usage.
But a n/a build vs a twin turbo build.....for me that is a no brainer. I dont think I've ever owned a turbo car that hasnt made me happy when boost comes on.
You only need enough power to leave black marks from the exit of one corner to the entrance of the next, anything more is just showing off!
I would not do it with some random turbo you have laying around. Also a single turbo will probably spool quicker. Also a turbo small enough to be responsive on a short course will limit you on a large course.
So you might want 2 single turbo setups a properly sized fast spooling unit for short courses and a large one for big tracks.
I know guys that run turbos in EMod but that is to get the HP without the weight, I don't know if that scales to a C10. (you are going to need really sticky tires)
do you guys do the parking lot autocross thing over there? i figured it was an american thing to teach us how to park at the grocery store.
usually its set up to emphasize driver skill, not vehicle power or speed.
a year or so ago i watched a fella stuff his new-to-him c6 into a jersey barrier at an event. was sad and funny.
That sort of thing is called autotesting here. Usually all very small lightweight vehicles, fwd tending to be the fastest but there are some rwd cars. Usually the likes of MX5's or the open wheel Caterham type cars, or custom build.
Fastest cars would be sub 1000lbs
Obviously it does take skill...but if the car cannot accelerate or brake fast too, obviously it is at a disadvantage. I'd still turbocharge or supercharge mine if I had one lol
If you don't think turbos belong in autocross try watching Optima's Search for the Ultimate Street Car.
Several TT Camaro's and Corvette's and all highly competitive.
Mike Dusold's TT Camaro makes about 1K HP and he's always in the top five on the leader board.

nearly none are running wide open trim as well- and Optima's courses are slightly larger. Plus many run automatics and lock them in second gear.
turbos on a super tight autocross suck. The transition onto boost is tough to deal with. Most courses have a sweeping curve, and modulating in and out of boost on those will cost you time.
Also turbos are just going to make you even more nose heavy.
I'd build a kickass motor that has a high rev limiter. You'll shave more time not shifting than anything else.
I would bet the top who ever autocross people who run twins has a pretty big budget.Short courses will need smaller turbos to even get into boost atleast here at the events i been . If ur running on road course set up u will need bigger turbos or ur oil water temps are going be high. Asking if it can be done is very vague .sure it can . 1000hp in autocross is just stupid overkill and a waist buy adding extra weight. Road course maybe different were u can strech out the power but it comes at a price.
I'd wonder if heat soak would be an issue with the LSA blower but it is an option.
I've seen several C10's and even an F100 raced on OSUSC and they give a lot of the cars a run for their money.
Judging by the comments you should just build the same car everyone else does...or build your TT C10 and auto cross the **** out of it.
If everyone built the same car this hobby would suck. $.02
Heat soak is only an issue if you do not build in adequate heat cooling capacity for the system.
And exactly...are you building to win..or just have a ******* good time ? You have the turbos already there so use them. If you hate it then take them back off lol
