after all bolt ons I put on my car the 3.73gears 1.6 roller rockers lpp long tube headers n y pipe cold air induction 52mm Holley MSD ignition yank 3600 and a tune from pcm and a set of nittos I ran 13.0 at 105 I had my 60' down to 1.8 and know I could've hit high 12s but the computer crapped out that read time and speed at the drag strip so I took it home..I wanna do a cam now lol I just want mid 12s as I like to drive it alot lol any idea of a good cam with the mods I have thanks and do I need injectors with a bigger cam fill me in thanks.

 

Whats your da and race weight? If you get some good drag radials and get that 60ft down. You would be close too mid 12s. Far as cam goes. I would call ai or le for custom cam. You shouldnt need injectors for just cam swap.

 

cc503

 

I agree. Were you spinning, how do you launch ? Any idea what your shift points are ? These are worth a lot at the finish line.

 

nice work! do you have stock suspension too?

 

PCM did the tune I shift it around 5800 and its full weight car I'm running 275/40/17 nitto 555r drag radials and I'm brake stalling it around 2000 rpm when I launch but this was my first time in a car racing lol I have rear drag shocks as well I am still spinning a little yes i don't think I was warming the tires long enough

 

Need get some lca and a real tire. Nittos aint all that great. Also try just bring rpm up above idle . Then stomp it. Back when my car was just bolt ons. It ran best shifting at 6k.

 

Next time try launching a hair above idle and stretch the 1-2 shift to 6k. I don't know the recommended tire pressure for the Nitto's but try to find out. I do know people say the need heated up well. Good luck, you should easily dip into the 12's.
Travis beat me to the punch, I type slow.

 

Also weight reduction is the cheapest mod. I ran 12.3s ay 108 with your exact same mods. Good luck with your quest for 12s

 

Set those Nitto's at 22psi for a starting point.

 

Thank you guys very much for the input.. So what do you think about a little insurance for that camshaft. cc503 cc306 or a xfi292. I know there is a lot of differences without arguing over which is better tell me what worked out best for you guys...then I'll try to base my decision thank you all for the time to help a brother out !!!!

 

The 503 is a good cam. Lots of people have had success with it.

With stock heads and SCR, you generally want to keep the intake duration no more than 225 or so. I would not select the 306 or 292xfi cam for your application, those peak at ~6600rpm and will be relatively lazy under the curve.

The XE 224/236 also works well in a stock engine when ground on a 112 lsa.

You might end up needing to swap injectors due to the fact that 1993 models have 22lb injectors stock. Back when I ran bolt-ons and a 224/236 cam in my stock engine making 355rwhp, my stock 24lb injectors were at 110% duty cycle. If you do swap injectors, all you are going to need is 28s or 30s, max. I think a set of stock 26 or 28lb injectors out of a LS1 or LS6 car would do fine.

 

93 cc503 cam only and supporting mods. on a 235/55/r17. still working on the tune as well.

 

Wow that's pretty good time there !!! I'm gonna get the 503 and try her out thanks again

 

Or I may call Mr Elliot and see what he has to offer heads and a cam may make her run even better lol

 

Get the rest of the supporting mods, springs, rockers ewp etc first. Dial in the car and then throw the cam in with a new tune.

 

Got the rockers just need cam and springs.. Do the electric water pumps help much??

 

Ok called LE going with the LE2 setup. That man knows his stuff about LT 1s ....also gonna throw an electric water pump and a line lock and a set of 36lb injectors for fun!! Also picked up a set of lower control arms. Can't wait for next spring !!!!

 

Get those shift points up to 62-6300 and you'll drop 0.3 probably.
