Hey all.. trying to think of what to do to get ready for race season in a few months

After the cam my 60' times hurt a bit and the car tended to sorta lug after the 60' and then pick up real nicely.

I have my 2800 Vigi in there with stock 3.23's out back... I have a free restall waiting for me, but not sure if I should just trying throwing in a set of 3.73's to pick up some more low end oomph, or should I just bump the stall up to 3200?

The cam is a 224/230 XE on a 112 LSA.

 

I'm pretty sure if you bump your stall up you wont have AS bad traction problems as with the 3.73's, unless you also get DR's, or already have them. I'd go for the stall to save my mileage. Just my .02

 

most say go with gears before heads/cam. but since you already have a cam that means your overdue for gears . did you get the car tuned after the cam install, i cant think of what else would make it sluggish on the low end like you said?

 

Let me correct.. it's by no means sluggish on the low end.. I still cut 1.7's, but they're higher 1.7's than before the cam.. I race the car quite often and compare slips quite a bit.

The car pulls the front end up (not the wheel.. yet).. pretty high (see http://www.zmydust.com/images/holyhell.jpg) but then kinda drops back down almost like too much traction holding it back, then takes a bit to wind back up.. this didn't happen before the cam...

The car has a mail order tune from pcmforless.. which is ok for now, but I'll be looking into a dynotune as soon as the availability comes up.. not too many people have LT1 edit for OBD2 lying around to work on these cars.

and kwikist.. see my 60's.. I have a tire although I'm pretty sure I'll soon be pushing the limit of what I can do with these nitto's.. 1.7's are about as fast as I see people go with them, not sure if I'll pull a 1.6 with them.. although I'd like to.

 

I don't read I just type

 

well what rpm do you cross the finish line at ?
is your converter locked when in third ?

I would recomend gears to put you in your cars power band when crossing the finish line since the cam changed that

 

ide grab a quality set of 3.73s and drag radials for now, and when you decide to get the convertor restalled grab a set of et streets (and 12-bolt if necessary)...youll have that m/f walkin on its hind legs then .

 

I'm pretty sure it doesn't lock up in 3rd automatically.. but I'm not sure how I'd know for sure? Somewhere in the high 4k's or low 5k's in the RPM's at the trap. just watched a video to doublecheck, a little blurry, but the MPH was close to my trap speed.

But it does feel sorta out of the powerband at launch.

chevyboy.. i do have DR's read the posts lol...

 

Hey I would go with more converter and a dynotune first then swap gears. I switched from 3.23's to 3.42's and didn't notice any improvement. There are some LS1's that are running 11's with cam only with 3.23's. You probably want to go more than 3200 and go with some BFG's and you should be rolling. SAR2k has a 3800 Vig with boltons and BFG's he 60's 1.55's He also has 3.73's though. I would go for the verter. JMO. Later Clint

 

Off topic but why doesnt that guy in the LS1 have a helmet on!!!

 

Yeah I was worried that 3200 might be too low.. so I was thinking a happy medium of 3400 ... Hard to decide really..

I think after my Nitto's are up I'm going to go with ET Streets since I only use them for track use I need to get a pair of matching weld's for the back anyways

Oh, and this was a track rental so they weren't enforcing the rules too well, but rest assured I took that car out

 

I'd go with gears. My reasoning behind this is one side wants to spin up quick, the other doesn't. I'm having a similar problem with a mild stall (2400), 224/230, and 2.73's. It's nothing major, but I'm thinking at least some 3.42's (for me) will get both sides on the same sheet of music.
