Hello,

I've been posting on this forum for some time name under Stallion8797, so I hope I'm not too new of a face. I've begun to open a performance shop and will be starting with mainly focusing on these cars and their engine.

We currently have an intake, exhaust, manifold porting, and pulley set in the works. The intake should be finished and ready for sale within the next few weeks. It is similar in design to the one I had posted earlier, but much more visually appealing. The exhaust will be a Dual 2.5" with an X pipe, with options of with or without race cats. If all goes well the exhaust will be for sale some time in December.

The two new products that are in development are a pulley set and manifold porting. The pulley set will be more then just the crank and priced significantly more affordable then EVO Sport.

The Manifold porting will be on an exchange basis and will offer different level of porting depending on application. Throttle body porting will be added at a later time.

All our products will be dyno and track tested to provide our customers with rock solid performance.

This thread is mainly to gauge interest in the products we are offering. Once the products are finished we will offer member pricing.

Thank you,

Sounds great guys, thanks for supporting us.

As for the Throttle body, don't waste your time because at 75mm it will flow more CFM than most V8 engines can pull. and I don't think this 3.2L v6 is gonna suck more than 750cfm without serious mods.

Once you guys get things going, and start making some money I would seriously look into putting out CNC ported heads that really flow big numbers. that would truely rock!

I'd rather keep my car normally aspirated instead of going the turbo or supercharger route to make power. I would rather spend $900-$1,000 for a high flowing cylinder head instead of chasing the boost-dragon.


Hey if you guys are seriouse about this engine you should start building a demo engine with all your mods and parts, this would allow you to use an engine dyno, for more acurate numbers. If you are serious about a demo block I would order up the ML320 sleeve and piston kit from mercedes benz, so you can increase displacement to 3.7L. the ML320 I believe makes about 245 hp vs 215 for stock 3.2L.
Add to that your full exhaust and intake kit and pullies, you might just be able to squeke out 280-300 hp Normally aspirated, then and another 20hp with ecu tune and then Shricks racing cams. whoo knows what this motor is capable of when fully ported.

 

Build it (at a reasonable price) and they will come. Sounds promising!

 

+1

A stroker kit to increase engine capacity would be the the best similar to the way renntech has the 3.8L engine conversion, except resonably priced, that will net serious power gains especially for us srt- owners...

 

Nice to see Forum members taking care of each other. There appears to be genuine interest in the services you are talking about. I think you will get more takers as warranties start to run out.

Good luck and thanks!

 

As mentioned in the previous post, thanks for taking an interest in mods for the owners of this car...

I do have a few questions which makes me think you don't have all you ducks-in-a-row when it comes to the engineering of this power plant... First, which manifolds are you talking about porting ? And which pulleys are you planning on altering and what would be the diameter ? Most importantly, how are you going to port the throttle body ?

Also, why would you develop a 2.5" exhaust system when the exhaust manifold outlet and exhaust headers are only 1.5" diameter... Don't you think you should address that issue first ?

 

HDDP has been wrenching on these cars for a while now and has more track time than about anybody so You have to take his observations pretty seriously. That being said...welcome to the forum and good luck with your efforts on providing upgrades and mods for these cars. I think because of the deeply discounted Crossfires sales there are now a lot of new owners and forum members who are hungry for useful speed parts and mods for the Crossfire. I think an effective true dual exhaust system would be a good place to start. I already have the Magnaflow cat back. The good thing about that part is it uses two separate muffler/tips assemblies so If I later install a true dual system I can retain the Magnaflow mufflers. it would be great to be able to replace the restrictive factory four-cats-and-Y-pipe set up with a pair of high flow cats and X-pipe and true duals back to the rear of the car. I think the idea for a stroker kit is a winner to. I really don't want some high-strung 7000 rpm motor for my street car. A nice fat boost to the mid-range torque curve sounds like more fun to me !

Keep us posted and good luck...

i am more than willing to be open for any achievments that you may gain towards our crossfires. Please keep us udated on your gains and approx. prices. Thank you in advance for your time, care and concern with the crossfire. I also agree that HDDP is a great resource if you need knowledge on the entire workings of this car.

 

HDDP,

The manifolds in question will be the Intake Manifold. We will provide gasket matching as well as full ports. As far as the exhaust question, the manifolds are not something that every owner can simply bolt on, or would simply bolt on. My experience with cars is that you will sell three exhaust systems for every one set of headers. This is an issue that will be looked at in the near future, provided slaes go well with the other products. Header research is expensive.
The dimensions on the headers measure 1.5" on the primaries I believe and go into a 2.25" collector. Our main focus is to allow a system that will bolt up to both the N/A and SRT-6 motors. I have a 2.5" system on my car and everything runs great, no loss of torque on the bottom end. If there is a greater interest we will develop different systems for the different cars.

As far as the pulley is concerned, we are looking at doing an underdrive crank pulley. I'm not not positive on the size, but figure 22-30% underdrive.

Like I mentioned before all of these modifications will be dynoed and track tested. We are located in the central New Jersey area, and will offer installation of all our products if need be.

The stroker kit is a great idea, but I've had difficulty finding decently priced MB parts. I sourced two ML320 engines in Cali, but they were a little overpriced and the shipping was crazy. I think this will be a project best saved for a later day. Once we have squeezed a decent amount of power from the stock size we will offer stroker and big bore kits.

Everything is planned over about a 14 month timeline for development and production. Look at it this way, in a little over a year our cars wil be as fast as they look.

 

good luck with the stroker kit, I would just order the Startech crank and have a casting company copy it. unless they are modifying stock cranks with more eccentric throw on the bearing surface? sounds like a lot of work, but if it was available I would probably buy it if it's a new forging and and made at least 80 hp, I could easily go $3,000 for that.

 

I am located in new jersey as well if you need any test fitments at a discount price you can rely on me... and yes about the stroker it is something we REALLY could use... as we to some point already have access to parts like pullies and an intake system.. well competition is good, but anyways..

for the stroker there is no competition... AT ALL...

 

I was looking over the Startech 3.8L stroker kit and and it's really nothing special, what they are doing is installing the 3.7L ML320 sleeves and pistons in your block and then somehow are increasing the stroke by barely a smiggin' probably doing some mild machining trick to increase the eccentric. so your only gaining 0.1L with thier so called "Stroker Kit" plus they are installing the Schricks sports cams and doing the ECU reflash to bring the performance up to 300 hp, 291 lb-ft

I also think thier big brake kit is the C55 front rotors and AMG 6 piston calipers.


STARTECH uses the sports camshafts and a high flow catalyst in the exhaust to bring stock power up to 243 hp.

 

One thing at a time guys. I want to be different then all the vendors that get your hopes up and never deliver. There has to be at least ten diferent twin turbo proposals on here.

Let me provide you my first produt which will be an intake, if you like it we will go from there. I will not ask anyone to put stock in something that has produced nothing so far.

I love the feedback though and it really does let me know where to focus our time and money. I promise that this will be a very productive venture I plan on going on, both for us and for the Crossfire owners.

 

I would really like to see an intake that alows the stock boxes to stay in place or at least something mocked up to clip just the tops on with very little Modification. That would sell the best on here I believe. You could very easly buy one box and run the intake pipe through it that would be sweet I know im just dreaming but I would be willing to pay more for something like that.

 

well thank you

 

OY VEY... Another intake ?

 

yup another intake threaed but the guy has to get his feet wet and bring in some income to build his business, this is easy to manufatuer, and most of us have all the tools and equipment to build speed parts, but we're too busy making money at our jobs to find the time to make our own speed parts. So I wish him the best and hopefully things go well!

All I ask is that his intake kit doesn't use K&N filters, they are crap and just allows more silica to enter the engine and contaminate the oil. not cool IMO

 

Well here you go. This is the prototype for the intake. It fits perfect and looks pretty good.

I do apologize to some on the board, but our kit does use a K&N filter, but only because it was the only filter matching the dimensions we needed. Green filters did not have an equivalent.

This will be one solid pipe when complete, so don't worry about the welds. ALso the elbow will be black, not blue, unless you really want it.

These will be put together, dynoed on two test cars (one an srt-6), packaged and shipped.

In the pic of the car the red circle is where the filter is located. It draws air in from the lower grille and radiator area. I've had this on my car for a while now and no rain, dirt, or other product has interfered with it.

Enjoy!!

 

If this were true how would they still be in business, let alone be the leader in the air filter aftermarket? I've heard complaints but have never seem proof of such claims. K&N is a stand up company.

 

I agree, some of us have painted our covers and would be nice to have an intake that allows us to keep them.
