Or, to if you want to go insane, and have a burning wallet, what about a turbo or S/C on the engine and a small twin turbo set up in the back? Main issue I see with this is space...

no one really needs a trunk right....?

cdrazic93 · 01-17-2014, 02:44 PM

probably a tuning nightmare, but who cares, becauseracecar.

Yeah twin-charged cars have always been difficult to tune correctly, but it can certainly be done. There is at least one member on here who was going to use the Innovate/Sprintex kit with his own turbo setup but I can't remember who it was now.

I think an Innovate/turbo setup is probably the best one and not trying to use two turbos together.

Search MRT performance from Australia. They're the only ones I know of that did a twincharge setup.

I want this now!
lets see a kit that requires NO intercooler and no custom exhaust manifold should definitely cost significantly less that regular turbo kits. But
I'm guessing that there's a ton of idiots willing to dump $5k on this it WILL cost a ridiculous $5k. I expect this to cost less that the cheapest turbo kit available ($3,700). I'll give you $3k right now!

SStratos · 01-17-2014, 11:22 PM

Anyone here with one of the "Twins" and a turbo on top be able to give us some numbers on their HP and Torque numbers along with fuel economy before and after the install?

Ludacrits · 01-18-2014, 02:50 AM

I'd buy it if it wasn't 5k. Just so we could get more info about it. If it was around 3k I could afford it and try it out.

Ludacrits · 01-26-2014, 03:26 PM

We need a fa20club sts turbo throw down pot. If I can get 1k I'd pay for the rest and I'd be a guinea pig.

ScottDRFT · 02-13-2014, 03:46 PM

Bump, did anyone get this kit?

Coheed · 02-19-2014, 10:30 PM

I'm going to be stopping by STS next week to check out the car if it is available. I would love to be able to drive it and give you guys my impressions. My co-worker used to work at STS and he speaks rather highly of the system.

There are many benefits to running this setup as others have already said. Keep in mind though, the Comp turbos will require a service at 50k mile intervals. I would imagine the grease used in the bearings is similar to some greases you can find on the market with a temp rating of 3000*F. Sounds crazy to me, but if the greased bearings actually work then this setup could be worth looking at.

One of the big benefits this setup has for a turbo kit is the factory fans are retained, engine bay is cool, lower CoG, and very little weight gained. The whole turbo setup is supposed to weigh only marginally more than the factory exhaust/muffer.

Ludacrits · 02-20-2014, 12:15 AM

STS guys give me really vague responses and just give me the "competitively priced" bullcrap when I ask for more info about the setup. These dudes seem shady to me.

Coheed · 02-27-2014, 04:09 AM

As promised, I went to STS turbos to check out the kit and I have some initial impressions. They had 2 cars there with the kit. One was manual with intercooler, they also had a customers car that was automatic without an intercooler.

The fitment of the setup is really quite elegant. It seems to work really well for the car. Installation looked pretty straight forward, and about the only thing that looks to be complicated about the install is routing the coolant lines. The lines run around the fuel tank and seem to have plenty of clearance to prevent rubbing.

The kit itself is pretty nice. The fab work on it is really good, and the mounting points on all the pieces are solid. No rattles have been experienced.

The Comp turbo supplied on this car was a 450hp unit. The center section of the turbo is no longer a hollowed out Garret CHRA, but a full aluminum Comp setup. The comp turbo looks really good back there where the muffler used to be. One thing we did talk about is the weight of the parts. The turbo replaces the muffler. Not knowing how much the turbo weighs, I didn't get an answer to how much weight the kit is in comparison to the stock stuff. But lifting the stock muffler, it certainly seems like the turbo will add no extra weight to the car.

I didn't get to drive any of the cars, because they are still working on getting them dialed in. They don't do their tuning in-house, but rather a close-working 3rd party shop handles the tuning side of things.

The system retains all the factory exhaust, and the rear flange is cut off and replaced with a slip joint for the turbo system to slip on. The connection seemed really tight, so there is little worry here with the slip joint for me. The pipes are ceramic coated inside and out. The boost pipe is smaller than you would expect in a 450hp capable setup, 2" hotpipe going to the intercooler. The intercooler cold-side is a 2.5" and it expands to 3" for the MAF housing.

I probed several times to really be assured that lag or transient response are concerns to be addressed, but they were adamant that the setup was very responsive.

The base setup here was 5psi, and you can see full torque hitting around 4500rpm. I suppose this is in the realm of what most 500hp turbos spool at. It is making power sooner than the supercharger kits, with more headroom for more power.

Still, I've yet to drive one. I was told that I could drive their shop car after they are done with the tuning and have it road-worthy. I'll certainly make the trip again to go check it out. I am not too worried about the boost-onset, but I am very interested to see how the throttle responds once the turbo is in the happy zone. Transient response is of the utmost importance.

The setup has a lot going for it. It's very desirable from many different angles. Oil scavenging is no longer a potential reliability risk. The Comp turbos really seem like they are trying to make a name of themselves. The kit shouldn't add any weight, no heat in the engine bay, stock cooling system fans and components without modification, low center of gravity maintained, no header to cause cracks or potential reliability issues down the road, no cold-weather limitations, no washer reservoir modifications, no extra stress on the front of the engine, no special belts required, CARB approval is coming, no need to worry about upgrading exhaust. Though, I do wonder how much more power is available with cats deleted with headers etc. 260whp on 5psi is pretty good. I'd love to see 10psi on this setup and really get that turbo kicking.

So, these are my preliminary thoughts. Feel free to ask me any questions about the setup. I'll update again once I get to drive it, and hopefully see whether or not this kit can deliver the power quickly enough to be a viable option for us. After talking with the guys there and actual customers, the claims are favorable.

All I ask is for a video of when you do get to drive their shop car. I want to hear this thing go.

What octane were those graphs generated on? What is the 220 whp run? Non-intercooled or something?
