Thought I'd share my numbers. This car is no dyno queen, but it drives better than stock. Moves out well with light throttle and gets good gas mileage.
The before numbers are with PRC stage 2.5 243s(stock cumbustion chambers), varraram cai, underdrive pulley and Thunder Racing v.3 "cheatr" cam (219/230 .607 .604 117)with stock exhaust.
The after numbers are with an unported FAST 92/90 and TSP headers and Xpipe.

Also, it ran 12.29@117 in +1200 DA before the headers and intake. If I remember correctly there was a strong headwind. Going back to the track this Sunday to see what the gains translate to on the strip.

Nice. I think most of your gains were from the headers though.


I don't think your cam is big enough to take advantage of the FAST. I say that because typically h/c/i cars are in the 440+ range.

Would have been cool to see the gains from each right on the dyno. Headers, then fast.


In for track results. I am running a 219/231 cam myself in my setup. Nothing wrong with small cams. I was hitting low 12's at 120. I was hoping to add headers and trap deeper in the 120s.

quickc5zo6

I don't believe all the gains were attributed to the exhaust, but im sure most of the gains were. I think 30-35 hp was from the headers. The intake definitely increased airflow to the cylinders. I also have stock compression and an LS7 clutch that has been dyno proven to eat 10 rwhp. So with just thise 2 would put me in the 440 rwhp range.
I have also seen dyno sheets of stock CTSVs make around 422 rwhp on the same dyno. Who knows, what im after is track results though. When I ran the 12.29 there was a auto grandsport at the track trapping 109. Conditions weren't that great. This Sunday should be better as long as there's no headwind.
But if you're going thru the traps at 120, you should be in the mid 120s with headers and off road xpipe. What was the DA on that pass?

mchicia1

1) Haha, tell me about it with the LS7 clutch. I felt the weight of that thing immediately when I put it in. My car doesn't even dyno 400 rwhp lol. It's a lower compression forged 347 and I have ls3 heads/intake/ls7 exhaust with a babyish cam. It has never been a dyno queen with this setup, but always ran pretty well. I have no idea why it dynos like ****. The dyno doesn't match the trap speed.

2) The DA of my 120 mph passes were around 500 ft or so. It was cool around 58, but humid. I am going with the catted headers though...I hate that exhaust smell with catless. Waiting for xspower to come back out, but I had my eye on the TSP ones too. If I can hit 122 mph, I will be ecstatic because when I first dynoed this car with 241s and a bigger cam, I only made 340 rwhp!

Does your exhaust have that catless smell with your cam? I would think since you have such a baby cam, it might not. Where my cam differs from yours is the lsa, I am on a 111 vs your 117, so mine will definitely smell.

quickc5zo6

The dyno you're going to might just be stingy. Different dynos like to spit out different numbers. Even when they're the same type of dyno. I take the numbers with a grain of salt.
The TSP headers aren't bad. As you probably know they're stainless now so that's a bonus. I have no issue with them except if im roll racing and rolling in gear at a high rpm (6k rpm+) they'll make contact with the floor and I will feel some vibration. If im getting on it from a dead stop and rowing thru the gears I wont get any vibration or contact with the exhaust and floor. I think they're a great deal.
My car does get the catless smell, but I've smelt worse with larger cams with tons of overlap. But I have a higher threshold of what I can take in that sense. I dont mind the smell cause it constantly reminds me of race cars and I don't drive it everyday.

mchicia1

Ha, I agree with dynos, but this was the same dyno I always used. The same one where I hit 460 rwhp in my old h/c/i setup. And the same one where I hit 459 in my cam only GTO.


All I know is I don't care because all that matters is how it runs at the track and against other cars .

I drive mine every day, so cats are going on.

quickc5zo6

Going up against other cars is a great way to gauge the performance of your car next to the drag strip. Dynos.....not so much. I've seen cars put down hero numbers on a dyno and perform like poop at the track and vice versa as in your case.
Im looking for 122 traps also. If I go faster I'll be pretty happy. I know my ETs won't be anything special consider I will be launching softly to avoid braking somthing. Im pretty gonna use the same technique as my 12.2 pass. Im confident Iit will net me atleast a high 11 second pass.

Kreeess

impressive numbers especially for that cam!

skyavonee

Solid gains across the entire range.

quickc5zo6

Thanks! The most impressive part of this setup IMHO is the driveability. It moves effortlessly in normal acceleration. It doesn't feel like i'm driving a six cylinder cruising around town like some big cams do.

PRE-Z06

Nice results, very similar numbers to my sleeper cam (218/230 .605/.604 116) that I custom speced back in 2008...numbers are in sig profile if interested in comparing, I used to tell people the car was stock unless they looked under the hood and saw the CAI or noticed the headers

quickc5zo6

Your cam is very close to mine. I hope my track times are similar to yours too..but I doubt Iit. You have 4.10s, don't you?

PRE-Z06

Yes I did and the lighter clutch probably offset the difference in drivetrain loss on the dyno numbers. Don't hesitate if you have questions about track tips or anything else, good luck.

quickc5zo6

It looks like the track day I was going to with a bunch of buddies is being postponed. I'll post up numbers when I go. Kinda sucks was looking forward to making a few passes tomorrow.

quickc5zo6

Went to the track yesterday...track prep was garbage but it was opening day.
Was getting lots of tire spin (Nitto drag radials). My best 60ft was a 2.05 and a 11.80 ET. Best trap speed was 122 and some change.
4.10s and a real tire are my next mods...along with a clutch.

fastrob691

What was the air like???

quickc5zo6

DA was around + 330-400ft

PeteZ06

Great numbers... You easily have a low 11 sec car!!

quickc5zo6

Thanks brah! Gonna go back to the track before I get my diff built and 4.10s. I'll keep this thread updated.
I would love to try for low 11s with how the car sits, but I think i would end up breaking something. With a built diff and gear though...i'm shooting for 10s...high RPM clutch dumps here I come.

BTW..I think I seen your car in the Hoffman Estates/Dundee area before. Looks even better in person.
