If that is the case, I'm going to start calling around and seeing what the minimum amount is needed to get someone to make it. I have some pretty good connections within the racing industry. If I have to, I'll just buy 10 sets and then sell them overtime on here.

Thoughts?

 

well so far there are none ... we had a member try and use SLK320 ones and it did not work out ...

you have a set made that can fit either SRT-6 or regular i am sure you will see plenty of people on it ... i am interested to see them made as well, would love a long tube design, stainless of course ... would definitely something i would buy, price would dictate how soon only, not if ... quality would dictate if i would buy them ...

 

You're right, the Super Sprint headers don't fit the bends in the car, but they fit the flange of the engine... I already have a custom set of headers in the works being built by a local race shop. One off ceramic coated that were carefully designed using the engine specs and a computer flow program. which included the additional lift and duration that the Schrick cams will provide when they are installed. My one off cost is going to be $2,700 including the design and analysis elements... But I am not going to ask them to make additional units, because the price is too high... IMO... And, based on their computer program, they only expect a 5hp increase...

 

ah, nice hddp... can't wait to see the outcome... too bad they can't produce them for less considering they had done the analysis already...

i'll be waiting to see the pictures of these... keep on troopin.

 

Yeah those headers are pretty efficient for OEM, but hey what do you expect from a benz.

The only improvement would be to the entire exhaust system after the headers. And opening up your intake. Not sure if SRT6 uses an intercooler, but since its Mercedes It probably does, so a larger more efficient intercooler might help.

I don't really see any need to mess with the SRT6, it's pretty much done except maybe computer tuning. And some weight loss, I would just leave it alone.

 

The car does have an intercooler. Using larger more efficient cores is going be a little work. Basically the route you are going to have to go is to purchase a set of laminova cores, remove the SC, bore out the existing cores to the new size and install.

If you want to try and use a larger radiator for the intercooler system you will need to watch pressure drop.

 

You guys may not be familiar with my65cuda.
Rest assured that if he is going to work on modifications, they're going to work. He's got close family and friends that are some of the most respected people in the drag racing industry. Not just drivers, but engine and chassis builders.
If he's going to take a look at something, rest assured that it won't be a back yard hack.
The computers may say that there's only 5 hp to be found. If that's true, he'll find it.

I'd love to have access to a small portion of what he's able to see and touch.

 

Well you have to remember, my father is into the older items far more than the newer stuff. Although, I have to admit, a few weeks ago we had Tom Hoover in town. He is the man that invented the 426 hemi. The smartest man I've come across in quite some time. The funny part, when chrysler decided to come back with the hemi, they sent a team of engineers to his house to find out what they should do.

The main thing I want to look at is easy bolt on stuff. Obviously I'm partial to the Srt-6. We're going to install the Renntech mods at the track so we can do a real world back to back test. Next weekend I'll raise the car up and have a peak at what's underneath.

 

Your father has been into some serious stuff. Old Hemi's and new engines may be a bit different in execution, but physics doesn't change. He still knows how to get air into a blower, out the ports, and get the most out of it in between.

I'm looking forward to what you find. My car fund is ear marked the new parts I'm dropping in the hot rod but it sure is tempting to mess with the SRT.
How many miles do you have on your SRT? It may take 3,500 or 4,000 to loosen up. They've got a long break in cycle that is held in check by the engine controller. Once it lets go, you'll be able to run a little better.

 

Got about 1,500 miles on it right now. I've put 1,000 on it in a week. I tend to drive a lot.

First thing I'm going to look at is high flow cats. Has anybody tried just punching them out and seeing how many codes get thrown.

 

You can just remove the back two cats all together and it wont throw any codes, there are no sensors behind them.
I'm thinking about doing it, along with removing the resonator.

 

if your gonna pop out the front cats, you will need O2 simulators.

 

NOT TRUE.

NOT TRUE.

 

Care to tell me what part of my quote is not true?

 

If you don't need O2 simulators when removing all the cats, how do you get around the problem of having emission sensors from throwing codes?

Please articulate what you know ...

 

HDDP, can you add more to this?

I talked with Kleemann about making some headers. First off, SUPER nice people. If I hadn't told Renntech I was getting their computer and pulley, I would have gotten it from Kleemann. Anyway, they said they would build a set of headers, but they'd be expensive as hell and no clue how much performance gain you'd see. They'd also need a donor car and would want to do it during the winter when things slow down a bit for them. He said the cost would be around 3k a set. I assume most aren't willing to pay that, especially when limited to the SRT-6.

I'm throwing the car up in the air today to get a look see. Hopefully I can figure out something. I want to make a true duel exhaust and get rids of these cats. Does anybody make o2 sensors for our computer? I emailed Kleenman about programming the computer to not throw the code, if that was possible . We'll see if they get to me over the weekend. Has anybody put high flow cats on their car yet?

 

Kleeman's price is about right for a custom header, the set I have on order (pending $) is going to cost me $2,700. I had Burns Stainless do a flow analysis on the engine to determine the optimum design for the N/A Crossfire. Obviously doesn't equate to the SRT. But the OEM headers and exhaust system are VERY restrictive. I would guess a good set would boost hp by about 5-7 hp.

Still haven't found anyone who has an 02 sensor bypass. And that does pose a problem if you start messing with the cats. Mine have been removed completely and i believe the sensors are trying to dial back the fuel mixture and leaning out the car.

Either way, I think your best bet is to clean-up the airflow on this car, intake and exhaust.

 

Has anyone compared the SRT6 header to the NA header? are they the same part numbers?

HDDP...
I'm still wondering why you said my earlier statement was not true?

My car does not have sensors behind the rear two cats, so how would the computer know if they were removed?
The front two cats would be a different story though because they have sensors.
