Well I was talking to the guys at SLS, about custom fabbing a turbo kit for me. They said it could be done for roughly 3,500-4,000. Thats with everything, FMIC, Turbo, Hard Pipes, Badass manifold, BOV, and tuning. Now my question to you guys is this, go turbo or go with Tag's Lysolm? They both will net me the roughly the same gains. But Nick told why take power to make it? He has a point, these guys do awesome work. He told me when he was at PIR when they were at the booth Hahn was asking them all sorts of questions. He told me not go with Hahn either he said quality is below average for the price you pay. SLS also has a 10 second Integra which is the fastest FF daily driver within 4 states.

I just think the supercharger sounds soooo much cooler!

 

Bump for more input

 

If it is street driven, supercharger. If it sees alot of track time, turbo.

A supercharger is more reliable and easier to deal with for a daily driver. The turbo does make more power in the long run though but has more parts which means more can go wrong.

My $.02

 

they both offer tremendous advantages... its all personal preference. The whipple will put added pressure onto all the components, and the crank, while the turbo doesnt greatly effect the crank or pulley system on the car.

 

Eatons are very reliable. Twin Screws superchargers need tight tolerances and aren't as reliable and maintenance free as an eaton.

 

I would go Lysholm simply for the lack of lag. But it depends on your preference.

If you only do straight line racing and are looking for max power, turbo. The lag will help from spinning off the line.

If you are looking for a road or Auto-X I would go with a twin screw. You want instant power the instant you hit the pedal regardless of RPM.

 

True.
I would still stick with a blower in a street car though.

Although if the pockets were deep or there was another daily driver, I would go turbo.

 

If it was me.. i'd wait.

 

Any eta, on when the blower swap for our cars will be avaiable for public purchase jim?

 

Rice Eater from the RL forums snapped his crank in two
Back on topic

 

How high does he take the revs up to?

 

Jim, does the whipple really limit it you to about 350 hp? I'd really like to go with the whipple, but my goal point was right around 400 hp. Any chance at all of hitting that?

 

From what I understand, he was around 7800 rpm when the crank let go.

 

NO!!! You could easily make 400+ with the Lysholm!

 

Safe to assume the engine wasn't balanced? That is pretty high if that is the case. Something had to give eventually. Musta been nasty.

 

I still don't see why ppl just don't build a High compression 2.2 and put a good bit of Nitrous through it. yeah I know people like the s/c and the turbo's but nothing is more consistent then Nitrous. for what you are going to spend on a turbo you could buil a 2.2. just a thought

 

So why would he say something like that?

 

You can only run so much nitrous without tuning, and currently there isn't any tuning out for the 2.2 Cobalt.

 

Maybe because with stock pistons its not safe to go more than 350 hp.

 

We honestly won't know what the limits of the blower will be. If Tag is willing to modify them like Whipple did they could have the potential of 20,000rpm and 35psi.

The fuel system will be more a limiting factor than anything else in my opinion. You can beef internals, but until someone creates a controller for a second set of injectors 60's are as big as we are gonna go. 60's at idle are below their minimum pulse width as it is. I couldn't imagine trying anything larger.

 

Mine idles at 1100 rpm and its smooth. A set of 160 lbs/hr injectors would simply have to idle at around 2500 rpm

 

Stilgar, here's my stand on this one. I'm favoring the blower to keep the car a SS/SC. I want low end power and torque and instant response when I romp on it. I have driven turbo'd cars and supercharged cars, and I prefer how a supercharger makes power over a turbo. I'm only aiming for 350whp to be easier on the tranny and other parts. Above that amount of power, a serious in depth build would be require for both the tranny and bottom end. 350whp will put people in the low 12's/high 11's with the proper supporting mods. Below are the Pros and Cons of each as I see it. There may be more depending on personal preferences and goals.

Supercharger Cons
1. Takes power to make power.
2. Oil changes required for the blower every 12000 miles.
3. Horsepower and torque downlow will make traction an issue.

Supercharger Pros

1. Makes full boost at 2000rpms.
2. Has a self contained oiling system.
3. Requires less effort to install and keep it clean under the hood.
4. Very reliable and consistant. +1
5. Great low end HP and TRQ all the way to the top end with any lag.

Turbo Cons

1. Intricate setup requires more involved installation.
2. Drilling and tapping for oil lines required.
3. Requires time to properly cool down oil after running to prevent bearing failure. Turbo Timer needed.
4. Lag down low, how much depends on several factors.

Turbo Pros

1. Makes awesome power up top.
2. If running an air-to-air intercooler, setup can be extremely efficient.
3. Doesn't require power to make power.
4. Doesn't require a specail oil change for itself.

 

Well, there are such things as turbo's that spool rather early. There are two in particular that could spool really early for the Balt and make up to 400whp or so, yet have the spool similar to a supercharger. The GT28RS would spool as early as 2500RPM's, making 350whp at 20+psi and the GT2871 would start spooling around 3000-3500 and making over 400whp with some higher boost levels. Mid-range would be enormous compared to S2 SS/SC right now.

Regardless of everything I just said..I would still have supercharger. It will always be more fun, and easier to drive on the street. That's an understood fact.
