Rise,

Since you saw my results with the 226cc heads and btr cam, and we have the same headers (1 3/4 primaries, 2.5" collectors, I had cats and their y-pipe though) I will let you know asap when I put on my Kooks and x-pipe set-up and ran. I have a feeling that they are decent/great bolt-on headers, but are restrictive in the CNC'd heads we are running. Seeing your results give me the feeling I may be right on my assumption of them holding me back.

Side note, Maryland Speed and some other vendors have facebook promos for percentages off items from time to time, picked up a Fast 92 for under 800 this spring, food for thought if you're patient.

I didn't realize the Stainless Works headers have 2.5" collectors. That will definitely hurt torque output.

To be honest, throw some TSP 1-7/8" headers on there if you don't want to blow up your budget or ARH/Kooks 1-7/8" headers with the HVMC. You'll probably pick up 20rwhp with just that change and close to that in torque. Iron out the tune issues and you could see 440rwhp and 400rwtq. Throw a FAST 92 on there and 450/410 are possible.

I didn't realize it either. They were already on my car when I bought it 7 years ago. Did some research after my dyno numbers. I expect some large gains from the headers, and getting rid of the y-pipe setup and cats on my car. Rise will see some nice gains as well.

BrntWS6 on here had Kooks True Duals and 1-3/4" Kooks headers on his car with TSP Stage 2.5 LS6 heads and the TQ V3 (231/234) cam. He swapped out the headers to 1-7/8" Kooks and picked up like 20/15. The 1-3/4" had the old stamped collectors and the 1-7/8" had the merge collector. The SW aren't as good as the original Kooks headers, so that's why I think you could pick up a ton of power. And remember, he already had True Duals. Those are worth a lot by themselves...

Getting these cars to breathe is the single most important thing you can do to reach your power potential.

Which is why I spent the money on the Kooks setup and a FAST 102.

Very true but the price of entry is probably more expensive than the whole H/C setup he has. It really comes down to how much your willing to spend.

Looks like the Texas Speed 1 7/8 headers is what I'll do. I'll just sell off the Stainless Works ones.

JakeFusion

That's why I suggested in the Dyno Thread that he sell off the SW and pick up the TSP. He can probably cover the cost or a lot of the cost of the TSP headers with the sale of the SW LTs.

Before you go spending a couple grand on parts, get a good tune first. Not a mail order tune, not a street tune, get a real dyno tune by someone who has a good reputation with these ECUs.

Through a stock LS1 intake manifold/TB and 1-3/4" headers, I made my numbers on Patrick Guerra's Mustang dyno and with the clutch letting go at 5000RPM. I'm sure you aren't being held back by the LS6 manifold or the 1-3/4" headers.

When I dynoed my car with AI 243s and a 226/230 cam, it only made 415 too. Took it to another tuner and I gained 20 rwhp. We did a before and after as well and it made dead nuts on 415 on the first pull just like the other dyno.

It needed more timing in the high end. I'd help you out if you were closer as I tune my own cars now.

The last dyno day I was at the dynojet was reading bad bad low. Cammed ls1 cars in the mid 300s low. A 243 headed big cam ls1 6 speed was at 380rwhp.

A friend who worked at a performance shop in NC said he had heard something from another local shop having the same deal with their dynojet. Something about a software update or something going on with the weather corrections as of recent.

I would run it at the track or find some other way to check it before I took those dyno numbers as gospel and started throwing parts at it. Even with the headers and intake you have it doesn't sound "right".

We can take care of the tune..
Lets get it set up to go on some rollers and dial it in.

Run it at the track and see what kind of mph you are getting, you said you were really happy with the power it was making before? Id expect that car to trap 120+ for the mods it has for sure. It would suck to add all those other parts to find out it was just a stingy dyno.

JakeFusion

iTrader: (7)

All those other parts would still make it even faster. It's not like he'd be throwing money away.

UDP, ported TB, and sell his SW LTs for some TSP LTs... he'd probably be out of pocket $350 or so. And he'd probably pick up 20-25rwhp regardless of the tune.

Call MD speed now or around Black Friday (which is right around the corner). I got a set of kooks 1-7/8" for only like $100 more than the TSP. The Kooks fit amazingly and they're not made in China junk like TSP. I had both. There's no comparison.

Glad you were brave enough to post your results. I had a feeling you would be disappointed with the #'s. I spent about 3 hours on the dyno dialing in my car when I put on the AI 226cc heads and it paid off. This included experimenting with timing to see how the car would react on the dyno. Yes the track is the real test to see how it performs, but I really believe in dyno tuning over street tuning with a wideband.

Before you go out and buy a FAST intake just be aware that I only picked up 10whp from a Vengeance ported intake with matching 92mm TB. The ls6 intake wasnt holding back the heads all that much at all.

I agree. I had the same mentality. A FAST 102 setup is just insanely priced for the power you pick up. Unless you plan on strictly staying N/A and want a max effort but you can easily spend as much or more trying to gain another 5hp NA than just going FI.

That's $350 that would be better spent on a dyno tune and there's nothing for him to install or swap out. He may pick up 50-60whp without even opening a toolbox.

The guy said he'd rent out the dyno for $100.00 an hour, which doesn't seem to bad of a deal to me. ****, with the tune that's in the car now, it wouldn't take longer than an hour to fine tune it on the rollers.

The tune that's in the car right now is money on the street. The street manners are great and the car feels responsive throughout the RPM band. I do think there is more to be had in the tune, but the only way to get that extra out of it is on a dyno, which we can setup. His dyno is at the Lake down Highway 42, right past the Shell gas station.

JakeFusion

I've said all along he needs the dyno tune as well. But if you're doing that, swap out parts ahead of time. Otherwise he's dyno tuning twice...

My motto is do it mother ******* overkill once or do it a whole bunch of times wrong.
