Thanks for all the great inputs you guys consistently provide! This time I'm looking for comments from:

- Guys who had a S/C, but then transitioned to single turbo or TT and why?

- Guys who went Turbo, then over to S/C and why?

I'm working through the decision process and want to make an informed decision. I understand that it depends on the goals I'm setting for my car, but am interested in why you swapped over from one to the other.

Thanks, Gordon

 

Had a Procharger, went to a TTiX setup.

Consistently broken or shredded belts, difficulty altering boost levels (pulley swap and in many cases, a different belt), damage to my alternator pulley (I had to tighten the system down so much to eliminate slip, it actually started wearing the alternator shaft!)

I know that not everyone has these kinds of symptoms. If you get your kit installed at one of the major shops you will most likely never have these issues -- they have it down to a science.

 

World War III is about to start...

Had Centrifugal S/C on a 32V Cobra
Had Twin Screw S/C on a 488CI (GTS)
Had Centrifugal S/C on a 347CI Factory Five Replica

Now have

Twin Turbo Z06
Twin Turbo GTS (switched from twin screw s/c)

Turbo's provide:

Better Torque
Better efficiency (no drag of belt on S/C)
Adjustable Boost
Compensating Boost for variable elevations/conditions
No belt hassles

Downside to turbos:
Bottom Mount: packaging/size
Top Mount: heat management

But, both S/Cs and Turbos can be made to go like stink. Pick your poison.

 

Good subject. I started with the A&A P1sc in 2004 and I'd like to say I never had a day of trouble with it for the 9000 miles it was on the car. It's a good solid kit and performer. I removed it last winter to install a TTi stage 3 kit. Mostly it was personal reasons; looks, reliability (real or perceived) and maintenance. The SC was IMO unsightly sticking off the front of the motor and looked out of place. The modified radiator shroud looked like it was home built. There was the constant concern of throwing a belt and having to tow the car home or worse, to a garage to repair it. The belts are difficult at best to R&R. I dreaded changing the SC oil on the ATI head unit. The blower although under a stock hood is not stealthy. I always had some jamoke ask me if the car was alright because of the rocks in a can sound the blower would make. The biggest reason though, The power is linear and you won't see max tq/hp until you reach 5000-6000rpm.

The current TT setup has lower maintenance/self-oiling, hung down low and less visable, less abuse on the drive belt system, power comes on sooner, especially in the power band I'm accustom to drive (2000-5500rpm) and almost 60#s of torque over the SC anywhere in the powerband.

I was not looking for more power, just a more usable powerband. I went from 490/444 to 493/507 and the power comes on around 3000rpm rather than 5000rpm and pulls to 6000rpm. 500/500 is not too much power that you roast tires just by giving it gas, but enough to beat just about anything on the road. The turbos are quieter. Oh yes, the TT Cache`.

If I had to go back to a SC(never would) it would be a Maggie. There's a bling factor that even the clueless can appreciate.

As for the install itself, the SC is hands down a cake walk compared to the turbo. I did both DIY.

 

I promise not to lob any weapons of mass destruction this time
1000000% agree

 

N/A all the way

 

 

Yea right

 

No reason for people who are happy with their superchargers to drag this thread off-topic.

I was in the same boat as DIYNOOB with my ProCharger. It had a taste for belts and enjoyed breaking tensioners along with power steering idlers.

I switched over to twin turbos and haven't looked back. *MUCH* more power under the curve and the car is now quiet once again.

 

I'm just gonna say "Hi" . Nothing more.

 

Never had a single problem with my Supercharger.

I have wanted turbos and the additional capability that came with them. Did not want to fight the belt issues that others were having when shooting for high HP.

Switched to the TTiX system and have been very happy with it. For roughly the same RWHP the increased torque is amazing.

 

That point can't be overstated in my humble opinion. It really is a night and day difference. A 650 rwhp turbo kit would spank a 650 rwhp supercharger car silly.

 

You are one to talk about being off topic as you are one who bashes SC more than most. I have nothing against TT setups and my DS1C has been one not to eat belts and it seems that the track guys at ECS and there are some of the A&A kits do a pretty good job of getting there SC cars into the 9's and maybe lower this year--so the under the curve probably is nill at the track, it is more about the driver

 

I did not mention the noise, because the noise was really a result of the headers more than the supercharger, but that was another big reason why I switched over.

As I said.. with my A&A kit I never had an alignment issue and as far as I know Bill who bought my kit never had an issue either. The kit was great for me and still is.

For what I was shooting for, turbos were the way to go. Hard to beat the blower kits for bang for the buck on the stock block.

As for one beating the other.. as far as I am concerned, whoever can put it down is going to win. Once you get to the 500+ rwhp point, traction in 1,2 and sometimes 3 because a tricky proposition.

 

do you run with drag radials on the street?

 

Have a P1 with the original twin intercooler. Not one problem in 9k miles, just a little sc whine. Drives and idles like a stocker.

 

Yes.. I run stock size BFG DR... 295/35-18

If you mean my sig picture.. no that is my CCW Drag Package.. that is right before the car went on the trailer one day to the track. I guess you know those are ET Streets and skinnies.

 

Unlike you I've had both setups and am in a position to answer the original posters question. I'm glad you're happy with your combo - my point was that has nothing to do with this thread. Even when my blower was dialed in and running perfectly it didn't compare to twin turbos.

Cheers,

Mark

 

Aren't there certain things that should be taken into consideration before the battle begins? Whats this guy using his car for? What about his budget? We all know that turbos are so wonderful, but they cost a damn fortune!!!

 

I've had them both and love them both.

2 x different SC on the C5 and 2 x TT on other cars a few years ago. All told I have had 2 x TTs and 5 x SCs over the years.

I never saw the point of anyone dissing one over the other - they both give you a serious case of PermaGrin(tm)
