Has anyone installed a turbo on there n/a crossfire? I tried doing a search but had no luck. I ould be very interested in this, I have a turbo that is not being used. I onder hat the hp would be ith a turbo if it as tuned for everyday use.

 

do a search on this forum. many people have attempted some form of forced induction and as far as we no none have succeeded. there is one thread still in progress... look in technical and modifications for V8 turbo diary.

 

The only turbo as of now on this forum was an SRT that the owner had the supercharger removed and installed an aftermarket turbo. If I remember right this thing dynoed over 400hp.
No N/A Crossfires on this site, that I am aware of, have had forced air induction mods made to them. It's just easier and cheaper to buy an SRT for boost fanatics !

 

There is that picture of a na with a rear mount turbo. Im not sure if he or she is a member on the forum.

 

Would any other forums members care to start a theoretical turbo thread with me? I'd love to make one myself but I don't know enough about turbos to confidently do it. I don't know how to compute BSFC without a dyno (if there is a way) so I can't really move past the turbo selection stage.

 

I have looked into a turbo set up on an NA. I did this witht he guys at eurocharged.
They came up with a viable twin turbo system that i think will work well.

Here is the problem. for less than the cost of putting a turbo together wit an NA one can buy an SRT6 ready to go.
Still I have pursued the concept. Last week I narrowly missed an 05 Aerobue coupe at $8500 with a stick shift and reasonbly low miles. Add to that the $7K to $9K for teh turbo install and you ar in the $ 15k to $19 K range.
I believe the performace of an SRT but with the stick shift tranny would be the result of this mongrel combo.

A decent SRT6 can be had for less than $15K right now.

so, why would you do it?

That said, their may come a time when putting a taurbo on the NA will make sense.
If you are serious, chat with Jake or Gregg over at Eurogharged. They did the original SRT revision to turbo. I would say they are best equipped to take on the challenge.


But not today unless you just wanted to DO IT.


roadser with a stick

 

I'm confident I can build a turbo crossfire for about $3k. I would only be paying for parts, which I would be getting either at a discounted rate if they are new or used for close to nothing. I personally prefer every detail of my car over an srt6 (nothing personal guys) the interior, the wheels,the wing. I see no reason why it can't be done, I have alot of people willing to help me with enough collective knowlege to pull it off. I am not in a rush to do it because I feel like I personally need to do more reasearch and further develop my fabrication skills (starting with a certain flat black car, which I am in the process of turbah-chargin' for much less) to accomplish the task. And the way I see it, I'll have 2 fast cars for less than the 07 mustang gt I was considering struggling to afford ($30k in 2008). Worth it to me. I know you would love a turbo roadster with a stick if it were cheap enough.

 

Sounds like you have your plans all worked out.

So, go for it.

Our lips are wet with anticipation of the results.


roadster with a stick

 

It can be done, it is not cost effective unless you have a six speed though. The auto in the limited and base has clutch packs rated slightly higher than the factory output. So you have to replace the clutch packs or swap in a tranny from a SRT6. Maybe one day someone with a manual tranny will boost their crossfire. Everyone (to my knowledge)who has attempted to boost their car so far has had an autostick.

 

Saw one of the Saturday morning car shows a few weeks back, think it was Gearz where they took a stock, new base Corvette and dual turbo'd it. The turbo's were in the back not in the engine compartment. There was a lot of tubing involved but the end result was a twin turbo set up that was basically invisible if you didn't know where to look. I have no idea if it would fit our cars but it sure did fit nicely on the Corvette.

 

I haven't thought much about the location, but a rear mount will definately fit. I would prefer to keep it as close to the engine compartment to reduce costs (more aluminum piping, more braided stainless line and an oil pump are needed).

The biggest issue has been adressed, which is the tuning problem. As previously mentioned, the AEM FIC-6 will work with our cars because it is compatable with CAN-bus cars and has a built in MAP sensor. It is a piggyback controller which costs about $400, and just either taps or intercepts existing wires from the PCM. There's no reason why somebody can't build a junkyard setup (besides the aesthetics) for super cheap. If the setup proves to be too powerful for the stock drivetrain there are other options that will work with some re-tooling. Hot rodding/ engineering is a magical thing in that you can do anything with the right bank account.

 

The TT Corvettes out there have been seemingly running the piping in conjunction with the sideskirts ll down the body of the car. They look sreally good and perform very well also.

A rear mount turbo setup on a crossfire would work, but you would most liely have to tub out some of the rear wheel wells to get the piping to stick close to the sides as well as create a true dual exhaust with two mufflers (if you have them at all), for the turbos...seems to me running a TT setup without a true dual exhaust doesn't seem very efficient to me.

 

This thread gets a giant .

 

Not that I'm going to be the guinea pig, but what are the limits of the manual trans as far as handling power? 300HP? 400HP?

Before I'd spend several grand on a turbo that *might* work, I'd just buy the Kleemann supercharger kit. Low boost and same numbers as the SRT crowd, both on HP and TQ. Sure, it's $7K but at least it's proven. And talk about exclusivity...

 

Our trans is only rated to 270 ft*lb, but there's no reason why stronger transmissions can't be swapped in if needed. Nothing drivetrain related is really rated in terms of HP because it's just a number, although it makes you go faster sometimes . It's called an NSG-370, and is also used in jeeps. My theory is that if it can handle the weight, and shear load of a jeep, 300 ft lb shouldn't be a problem in a crossfire. If I'm not mistaken, the classic hot rod formula is to buy the cheap model and make it faster than the top of the line model for less money.... All while using frankenstein parts and engineering skills to make something ultimately uselessly fast lol. A turbo setup making similar power to the kleeman would be safer and cheaper than the kleeman supercharger setup, as the supercharger increases the load on the engine in order to make power. If dudes in honda civics figured this stuff out years ago there's no reason we can't figure this out now . Plus, aftermarket companies only make stuff when there is an obvious demand for a product. Turn that frown upside down fellas.. WE CAN DO THIS!

Assuming you have no problem with the ECU handling the spliced in tranny's codes and the car will start you may have something. But consider that the turbo doesn't bring on extra power or torque untill 3000 RPMs at which point the torque curve begins to flatten and soon after descend So, you are unlikely to exceed the 270 FT pounds unless you develope more than 350 HP. I know, it's just a number.

Higher RPMs generaly mean fewer foot lbs especially after about 5700 so except for redline clutch popping, you will be within the capacity of the tranny.

Our twin turbo concept suggested a 300+ HP to start with 350 likely the limit with some tuning. I believe that is relatively easy to get cobbling the right parts together.

If it is your intent to make an NA dragster, You've got to plan on more than $2K to spend. I am pushing close to 290 HP on my roadster and the rear suspension is complaining already. Our Xfires are simply not built for drag racing.

So, if it is only about HP then slap on any old turbo and make it do. But, as you have said, it is only a number. If you truly want speed off the line, I think you have much more to do to nurse that NA into the 13's

An SRT is already there.

 

I know I've seen your mods list somewhere in the deep bowels of this forum, but what all have you done? (short version)

From memory, you've got a dyno tune, bigger injectors, CAI, rear cat delete. Am I missing anything? Those are pretty impressive numbers.

 

I corrected my post to 290. It is calculated from the dyno numbers from a baseline of 154 rwhp to start and a 193.5 rwhp at the end.
I admit to a little cheat. The posted nubers for the NA crossfire are 215 HP while the SLK boasts 229. There is not difference except a perception created by marketing. So using the 229 HP number you get 287.7370 HP.
Even using the 215 HP you get 270HP. Not really "Pushing 300 HP" Still impressive.

I did not mean to mislead and have posted these numbers before.

Eurocharged dyno tune.
19# injectors
Custom 3.0" CAI pulling from the passinger front fender box
Back Cat Deletes
NGK Plugs

The 193.5 WHP dyno was pulled at 90 degree air at 85% humidity.
DynoDynamics. Tony at the helm
It was the second tune.

Give me cool dry air and the car is on fire.

Any doubts, ask Jane Bridges if it can scoot.

You could do the hardware yourself and drop their stock tune in and likely get 175 RWHP. But nothing beats Tony and two hours on the dyno.

Haha I wasn't gonna bust your ***** if you were a few HP off... even the BEST dynos are approximate. IMO, 270~280HP is indeed 'pushing' 300.

That's pretty impressive. I certainly want to boost performance, but it's low on the immediate priority list. I'm simply enjoying the crap out of my poky little car. Three sacks of lemons later, and I'm still grinning.
