Hey all. Wondering what everyone's preference is for the TIB, Turbocharger or Supercharger. I know for sure there is a turbo, but i dunno super. Some of my friends say turbo, some say super. Also, if you could put a reason why you like that certion "charger" it'd help a lot! Thanks in advance.

I prefer turbo but I don't have it. My reason is that superchargers run off of the engine so they cut down some power to make themselves run while turbo doesn't cut down the engine to make it run

i prefer a supercharger b/c it is more reliable and technically safer for your engine. also the power for a supercharger is throughout the powerband. power CAN be increased on a supercharger by exchanging the pulleys. most kits will offer certain pulleys and have others available to you. <img src=icon_smile_evil.gif border=0 align=middle><img src=icon_smile_approve.gif border=0 align=middle>

I also prefer a supercharger... if your going to run your car with a turbo, you have to let it warm up for half hour first, or you'll mess up your engine! Rudy probably knows more on why that is, but that's what I think he meant about superchargers being safer.

Heheh... I don't know where you got that 30 minutes waiting info, but it's far from the truth :) It's true that you have to wait a couple of minutes before you can actually go, when you have a turbo, so the oil is correctly feeding the turbo. You CAN go as soon as you want though, if you can manage to keep the boost to 0 for a few minutes (5-10).

Anyone know the price differences. Also after more discussions with friends I'm liking the idea of super because it is available throughout the powerband. I don't race too often. If I went to the track alot I'd get turbo.

About how long of a delay is turbo lag?
And do you have to reach a certain RPM before the turbo kicks in?
I need something that'll give me that extra boost at lower speeds, say around 60kph.
Will the turbo do it or should I go with the super?

Okay, I can sorta make a comparison here. I have the Alpine Turbocharger, Yamanko has the Alpine supercharger. The comments below are directly relating to the two Alpine systems, not Turbos or Superchargers in general.

The Supercharger runs at 7 psi, with no intercooling. It is good for 45 HP to the wheels, properly tuned on an otherwise stock motor.

The Turbocharger runs at 9 PSI, with an intercooler, and it was good for 63 HP <b>improperly</b> tuned.

The supercharger should be good for 60 HP to the wheels with 4-1 Headers and a decent full exhaust, CAI and re-tuning (after adding said parts).

The Turbocharger should be good for 100 to the wheels with proper tuning.

The main advantage of the turbo, is that it is easier to make MORE power. More HP is just a few PSI away. Adjust your wastegate/blow off valve and add the proper ammount of extra fuel (proper ECU)

The main advantage behind the supercharger is instant throttle response, and increased power across the whole RPM range.

Main disadvantage to the supercharger is that getting more HP out of the S/C means replacing parts, and possibly a new pulley. The problem you will run into, is that at high boost levels, the supercharger is heating the air so much, more pressure will not produce as much power, and if turned up too much no additional power. The design that alpine uses does not accomidate an intercooler after the supercharger.

The main disadvantage to the Turbo is complexity, and turbo lag. But the alpine kit has no turbo lag problem. I am at 9 PSI at anything above 2500 RPM. The complexity issue is a different story. If the company that designed the kit, had problems tuning it...how well do you think you will fare? To be fair to alpine, they were somewhat rushed due to the fact that they had tickets already booked for a return flight. If they had the ability to keep my car an extra day or two, they could have ironed out a lot of the tuning issues.

Yamaneko has 2 problems with his Supercharger. #1. It keeps blowing off the fuel lines (or they leak) due to increased fuel pressure. Double hose clamps or threadded fuel line connectors would solve that problem. #2. In third gear, the RPM's are so low, the supercharger is only making about 2-3 PSI, so the acceleration (in 3rd, 4th and 5th gears) is somewhat slower than the 18 HP difference between the Turbo and the supercharger would seem to indicate. (keep in mind, the turbo is making the full 9 psi at 2500 RPM).

The main problems I have had with the turbo system are the tuning of it, and the poor quality fittings/bolts accessories that Alpine chose to use. I am slowly tuning it better as time goes on, and I will eventuall spend about $2000 total to scrap the 5th injector, and Uni-Chip in favor of a HalTec ECU replacmeent and 4 larger injectors. I am also slowly replacing the crappy hardware they used, and upgrading it with more reliable fittings, hoses, and the like.

Yamanko and I will be Dyno'ing the cars on October 6th. It will be interesting to see if the Numbers/Dyno charts Alpine gave us match the new Dyno's.

Questions?

In regards to which one is for you? If you want to stick to mainly bolt on mods, and make decent HP, but not insane levels, the SC is the way to go.

If you want more power, then even more power, the Turbocharger is the way to go.

I'm still trying to weigh the two.
But anyways, you said the alpine turbo doesn't experience turbo lag?
This was my main concern with turbo.

I have no problems with lag as long as I am over 2500 RPMs...which is 99% of the time.

Cool...
Has anyone ever gotten it to work properly?
Random I know you've had probs with the Alpine unit. Have you fixed all the bugs?
How much extra costs are there?
and what are they?
If all goes well I'll probably get the alpine unit ready for next year...<img src=icon_smile_tongue.gif border=0 align=middle>

If I were to take it back to a qualified Uni-chip tuning shop, they could fix it up, but Alpine is unwilling to foot the bill for such a trip. ($100 to $200 bucks)

Since it is MY money, I am just going to yank the uni-chip and the 5th injector, and install a Haltec unit and 4 larger injectors.

I have seen people give prices for the Alpine Turbo, but never for the SuperCharger...Does anyone know what that runs?

The low priced deal is $1900 for the Turbocharger and $1300 for the supercharger.

Contact Alpine to see if that pricing is still in effect.

THANKS A LOT! Random,you are a god in the world of tuning. Many thanks! I'm leaning toward S.C. Thanks!
