Hi everyone, Looking to do forced induction and have been searching the forums and threads for information/likes/dislikes of TT and SC.

Could I trouble you for your comments and TT and SC, which one you like? Ease of install, tune, maintenance, HP for price? Best efficiency, fuel? Which is most popular?

Even your experiences with one or the other would help...

Thanks,

Kev

All things being equal turbo is the way to go. However in a C5, I think SC is a better option due to cost, space constraints, and the fact that turbo cars always put out a lot of TQ which equals a lot of wheel spin for most people.

For me the cost of a TT kit (~10k) vs Centi (~5-6k) is a big factor. I would rather take the 4k left over and forge my shortblock, and pulley for more boost

Turbo will have better results. More low end, more high end at 6K+ RPM (less parasitic loss), better MPG. Not a dramatic difference, but its there.

But, on C5's, turbo costs almost twice as much as centrifugal superchargers, both in terms of money and labor. And supercharging will get you about the same power as turbo. Turbo set-ups are harder to setup correctly also, to get the right size charge pipes, exhaust set-up, turbo selection, and if you decide to up the boost and make more power later you might have to change it up more etc. etc., while superchargers are pretty tried and proven for given power levels, adn switching out the supercharger head unit is pretty easy. Also, in either case the limiting factor quickly becomes your tires and drivetrain anyway.

S/C about the best way to go with the vette's. Robert

Ease of install:SC
tune: equivilant
maintenance: no belt to break. Both hard on driveline parts
HP for price: SC
Best efficiency: Turbo
fuel[mpg?]:turbo
Which is most popular?: SC
All depends on what you want. Personally prefer turbos.

Oh boy, here we go.

I had a Vortech centri. The things I didn't like about it were messing with belts and pulleys, and the gear drive sound that goes with it. Now I have a TT and the only downside I can think if, is maybe the extra plumbing I have to remove & replace every time I blow my engine.

UPP offers a TT kit for $5500. There goes that argument.

TT is the best for everything except maybe cost, ease of install.
Go turbo if you can.

True, I forgot about them until last night. I am on the fence between the UPP kit and an ECS kit...damn choices

With SC kit prices went up and almost equal to TT price range, how can you go wrong with TT kit or even single turbo kit? with the exception of TTix kit which is even more but ultimate very nice though.

However either way SC or TT, there's pros and cons, period.....bottom line how much you want to spend is the question?

then you also have the TVS blowers that are virtually maintenance free, easy to install, offer torque earlier than turbos, and with some extra modding can provide good top-end power, too.

Word. The tvs 2300 or 2.9 Whipple are the bees knees if you want 7-800 horsepower on a nicely set up engine.

SC vs Turbo/Twins? Money vs Money vs likes. Personally, nothing sounds better than a big cammed/big cubic inch motor with a procharger.

TT's are awesome-gobs of low end torque-but all done by 6k.

Plus:

lots of extra plumbing, wastegates, bov's, oil feed and return lines.

With the added benefit of:

Lots of underhood heat so things stay nice and toasty

Did I mention the torque-that's great for driveline upgrades!

bradenW

All done by 6k rpms? lol Make the sale.

Arun@Dasilvamotorsports

I think I just sold myself on one for my truck!!!!!

joshtownsend

don't forget the unreliability of them and never seem to work but 25% on street cars.

there is a difference is price. but where you push 12-15 psi to make the same power as a 7-8 on a turbo, in the end you buying a 5-6 k super kit that is deap by 800hp or a turbo kit that will keep going for 10k.

Chris Stewart

...bov's, oil feed and return lines..." You mean like on your SC?

The only times I see real TT heat that's destructive is when I've run it lean and the EGT's go sky high. That will burn some **** up.

topdown01

I appreciate everyones input...pros and cons to each...will just need to make up my mind I guess.

If I were to go TT what is the best package that you would recommend?

Same for SC?

sitting around 370HP (cold air and Borla exhaust)...she really needs something else...

Thanks again, Kev

for a supercharger - TVS2300 or the new heartbeat design if you plan on keeping it under 10psi-ish. the new one is supposed to actually fit under the stock hood, too

i'm at 11psi on my 2300 and making 535h/545t with 500+tq from the time i punch it... all on a stock 2000 LS1 with 853 heads. no extra maintenance either
