Right now, with Mods in sig (stock tune), I'm consistently running 13.4s at about 106mph at Sacramento Raceway on BFG KDWs w/ a 2.1-2.2 '60 time.

Next weekend (hopefully) I'm installing a TR224 (224.9/224.9 .567/567 114.7/114.7) w/ 918s, TI retainers, 7.4 chromoly pushrods, LS6 oil pump (not ported), and LS2 timing chain.

I'm thinking with Cam alone I'll be good for 13.1s (I'm going to run it a while before I get it tuned - I really want to know how much the cam did and how much the tune did). Then after I get it tuned and up the rev limiter to about 6500-6700 I'm hoping 12.9's are in the cards. I think I'm being realistic in my estimates, but I don't want to get my hopes up and be disappointed with the results.

I'm also planning on running true duals with a magnaflow X-pipe after the stock cat's, but I really don't think that's going to help much as far as performance goes but who knows I am running a flowmaster right now.

So what do you think folks, will this get me there or am I going to have to get the LS6 Intake and !EGR and !AIR to get 12's and just hope the cops/smog shops can't tell the difference on the visual (lot easier to change the intake if I get caught then it is to change headers )?

Thanks,
Scott


BTW, I've been searching for months for a good example of what I'm trying to do and just can't find anything similar, especially with the current search issues.

Also assume the following limitations:

1. I want to really pass california smog - no hook-ups!
2. I don't want to get stopped by a cop and fail visual - no mid/long tubes!
3. I am absolutely staying n/a - no N.O.S., blower, or Turbo
4. All racing will be on true street tires, no DRs or slicks/skinnies - not swapping the 10 bolt yet
5. Raceweight will remain unchanged for the time being.
6. I'll likely be moving out of California in 2-3 years so I want to build with the future in mind (i.e. Long tubes will eventually be on the car, CheaTr cam wasn't right for the future)
7. I like to Drag race, AutoX, and Open track the car.
7. I don't race dynos, I really don't care what the HP is and I don't know my current HP is. All I care how it performs on the track and on the street
8. Ultimately with longtubes, heads, and FAST 90/90, in the next state I go to, I'm pretty sure the TR224 will get me into the 11's with DR's so that's the five year plan - Right now though, I have to get into the 12's!!

With a cam you should be mid 12's or better. I ran a 12.87 with stock manifolds, 80mm tb, and a lid. I have a M6 so it is completely possible to get into the 12s without a cam or even longtubes.

A lot of it is the track, I was 2 tenths faster in Maryland before my pully, TR55's, MSDs, and Lid then I am here now and I was 2 tenths slower in Germany with the same mods I have right now.

I guess the real question is, will I pick up 5 tenths?

I ran 12.2 @ 117 CAM ONLY with the TR224.

You should manage 12s, but your exhaust will REALLY be holding that cam back.

That's what I was thinking to, but I hear so many people talking about "don't waste your time with a cam if you don't have headers," but I had to believe I'd get something out of it.

I assume that was with headers though? I figure I'm giving up 30-50 RWHP without headers on this cam, just a guess though.

Get yourself a pair of shorties, at least they will *help* and get yourself a cut out. Those two exhaust modifications SHOULD help. I'd also try and get a 3" catted Y-pipe if you can.I'd also advise on getting the tune immediately, it'll be a waste of time if you don't. With everything above theres no reason you can't get into the high 12's on regular radials.

Actually cutouts before the cats are illegal too. As far as tune, you don't think I'm going to get anything out of the Cam by itself?

Im running the TR224 .581 .581 114, LS6 intake, pulley, and shorties. At Sacramento Raceway the best I've been able to do was 13.1 @111mph. And that was with a horrible 2.5 60ft on GSD3's. Dyno showed 388rwhp.

Ouch! But that might actually be somewhat encouraging when I really think about it. If your 3 tenths faster then me in the 1/4 and I'm 3 tenths faster than you to the 60' mark, sounds like I got a good shot at making up 5 tenths or so, unless my maths all jacked up.

Your MPH looks pretty good at least, thats definately a 12 sec MPH if you could hook up better I bet you'd be there for sure.

Do you have lowering springs on your car?

edit: just looked at your sig, yea I bet the pro-kit is definately effecting your 60'

Shorties & a tune should get you into the 12's. Sucks you live in CA. Longtubes would send you there easier. A lot of people have hit 12's stock.

I'm pretty sure I'd be there by now in Maryland, but Sac Raceway is just a bit slower. Seem mostly a traction issue, I was always running 2.0s and 2.1s in Maryland. Track prep I guess.
