Hey learn to read! I said i wanted to do the remote mount but the shop is against those kits and are wanting to keep it all under the hood.

 

darn, i wish i could read what you just posted

 

Yeah, come on mrphotoman! WTH?

We're not in Kansas anymore.

 

 

Is Speed Innovations even in business anymore?

We just hacked apart one of their ECUs. $500.00 custom tune, only change was 3 degrees advanced timing across the board. Same AFR as stock.

Good luck with the Turbo Tune!

Can you post a link to their Twin Turbo SLR I can't find it on their webpage.

Look, it can be done. Can it be done for cheap? NO. The thing I hate reading is all these cocky companies swearing up and down that they can make these things work. I have yet to see any TT MB cars other then one TT Crossfire that never ran (the tuner for that car actually lives nearme, we just met last week) and an E class with a swapped T56 tranny. And I'm pretty sure that car had a stand alone system.

I know LET was almost complete with their project and got a base map up, but that ended. I have a customer working on a rear mount kit for his C240, but, even though our hand's are in it, I won't even begin to admit that we can do it until we have some proof.

This is why I'm not going to Malaysia, that and it's Malaysia. It's been toyed with and in theory it can work, but I want to test this theory and blow my engine before a customer's.

By the way, here is a real TT MB that is nearing completion: http://www.mbworld.org/forums/c32-am...roject-12.html

 

Wonder why no one has ever posted up a completed turbo kit for the Crossfire? Let's see... maybe because one just needs to visit this forum and read all the garbage and pissy remarks from its members. It just screams, "We don't want a turbo kit!"

Let the guy head up the fabrication of the kit and hope for the best. I don't know him, you don't know him so shut the fu¢k up and let the man do his thing! No one knows his abilities so stop saying that it can't be done. Remember when everyone said that supercharging it couldn't be done??? Chuck Norris, thank you for proving the majority wrong my friend!

F-ing immature babies...

 

Sounds like you have quite a big project in mind and a fun one at that. It takes some big cajones (and a few $$) to attempt a project like this - due to the confined space under the hood and at the exhaust manifolds.

Once you get into it and if you really feel like you are going to have this turbo tackled - don't be afraid to spend a few extra $$ to make it right. Make sure you take good notes and make detailed lists of materials. If it works - you will have one heck of a hot conversion kit on your hands and it will soon pay you back for the extra investment.

I returned from a little trip to Nor Cal to help a friend move (in my SRT6) and when I arrived - this guy walked up and said he had just (last weekend) came back from Vegas in a twin turbo Crossfire. I asked if he meant an SRT6, and he said no - it had the electric spoiler and huge air-to-air intercooler and turbos on both sides. I asked him to call his buddy and bring his XF by (he lived about an hour away) but no joy.

Could have been a story but...I'm sure not all Crossfire owners live and die on this forum.

Good luck my friend and feel free to PM me if you have any questions.

SpeedInnovations has an awesome shop - state of the art Dyno-Dynamics chassis dyno, several lifts and work bays. A full on N/C mill and machine shop.

They were doing a custom dyno tune on a bad-as$ BMW when I got there and had finished on Porsche earlier.

He probably did a good 5-7 ecu flashes on various MB's while I was there getting my dyno-tune. Saw his twin-turbo project on a Ferrari as well as many different turbo / intercooler kits they designed and install for Mini's. Very nice stuff.

I haven't seen your garage TVT-- or your equipment -- but I'm willing to bet yours is pale in comparison with SI's operation. You can only dream of having the skill to tune so many different type of cars. SI has been tuning and modding euro cars long before you even heard of the Crossfire.

The reason most of the serious MB/AMG platform guys don't bother with this forum is the wae you folks treat them.

Wouldn't it be nice to see companies like Brabus, Kleeman, Renntech, or even ASP, VRP and Code3 discuss thier product or gauge our need on this forum?

 

ok after what brian said i feel that my point was proven. I may not do this still. I will not vanish. If i don't do it tvt will hear from me for their tvt265 kit. I am just wanting to bring something to the community. and i don't like the finish of Chuck Norris' supercharger. I feel that Mercedes products should look as clean and as profesional as they come from the factory.

We will see what we can come up with. I may have to argue with the shop and find a better way to route piping and what not to keep the finish of the bay looking better.

I will post as more info arises!

Thanks to all! And i will post up how much the kits will sell for when we approach that spot too!

 

these ecu's can be tuned. and getting a shop to build you some manifolds is no big deal. You can turbo anything! Focus on just making it functional then you can purty it up afterwards

 

Wow man, no need to throw a hissy fit. That was not very mature of you.

 

I just get a kick out of how the all people who think it worthwhile to boost a NAxfire have very little experience or knowledge in turbocharging anything.

You can't simply TUNE an ECU to read boost. It needs to have the software inputs to start with. And if it doesn't (the NAxfire has a different computer than an SRT6 and doesn't come with a MAP sensor) you need to perform the required tasks (timing retard and additional fuel pressure or injector pulse) with piggyback equipment. And if you support boost that way you need to ensure the stock ECU inputs (sensors) never go out of range or the stock ECU will throw codes. In a NAxfire you will only get to half a bar (7 psi) before you surpass the largest injector you can run (and still idle with). Not to mention the detonation risks you would be taking with high compression and the weaknesses of a NAxfire drivetrain.

A custom remote turbo setup...

Remote Turbo: Garrett GT35 (Trim? Exhaust A/R?) installed in stock muffler cavity. Fabricate brackets.
Exhaust: Lose rear cats, Y into 3" off center (driver side), maganaflow round muffler?, 38mm Wastegate?, dump/recirc?, into V-band turbine housing, out V-band turbine housing to stock tips.
Charge air: Out of compressor and up passenger side, Intercooler location?, into stock intake.
Oil delivery: RB Racing Scavanger pump to oil cap.
Coolant Delivery: T from heater hose, scavange back to radiator?
Higher Volume Fuel pump (SRT6?)
Aeromotive Digital Fuel Management Unit (increase fuel pump voltage while under boost to match boost)
25lb/hr injectors (enough to support 325hp with the increased fuel pressure but not so large the PCM can't adapt during closed loop with a custom tune).
Timing Control: Split Second FTC1 (-024?) to filter timing and MAF output against RPM and intake pressure to fine tune timing retard and fuel delivery in all conditions (piggyback).
Fuel Pressure Gauge
Wideband A/F ratio Gauge
Boost controller (10psi max for higher resolution)

And that doesn't include all the bracket/piping fabrication, tuning time, clutch upgrade, etc.

Nobody said it can't be done. But those of us with experience know it isn't worth all the cash and risks for just 300hp. And the best part of it all is YOU HAVE AN AUTOMATIC! LOL! What's the point? Just buy an SRT6 (never though I'd say that).

So they've been tuning for over 5 years now?

In all honesty I really did not know they were still in business. If they've changed their practices that got them in trouble over the last 5 years or so then I'm sure they are more then capable of doing this.

I'm sure we all just want to see some pics and results. Only so many times you can pass over a new TURBO post before you really start to hate them.

I wish the OP a lot of luck, and if the shop doing the hardware wanted more recognition they'd give you a great deal on the fab work.

It's going to be a great day when we have a SC, a turbo, and a NA kit all bringing these cars to the 300HP mark.

 

haha, your joking right? When it comes to turbo fi, auto is the best you can go with. Reasons? Um, no clutch time?

auto: You get off the line, spool that ******* up, and as long as your foot is on the throttle, you'll be at 8psi, all night.
Manual: OFf the line, spool up, shift, spool up, shift, spool up.

Superchargers blow. Parasitic loss anyone? How about a side of roots type supercharging renown for leaks? MMm.. sounds delicious to me!

Lets keep going with this idea... why not? Super charger w/ manual or automatic. Either way, when the rpms drop, Whoa, so does the boost. Imagine that. Turbo w/ auto, off the line, spool, and keep goin all day.

And SRT? With the money I'll be saving on insurance from having a limited, i can probably afford the turbo.

 

Actually the crossfire only has 2 codes with the insurance companies, 1 for coupe 1 for convertables, it costs you no more on insurance for a srt vs limited.

 

Come on now... do not bash manuals. That is just preference. I would rather have fun driving my car rather than stomp and hold the wheel. It is just dumb bringing yet another manual/auto debate.
