Hey guys,

I know this question was asked before .. I tried finding the thread for it but I couldnt find it ... Anyway, I'm currently working on a forged 427 block .. In the beginning I wanted a YSi kit .. Then I thought which one would live longer?!! :-/ .. I asked the garage I'm getting my work done at .. He recommended the turbos from start but I kinda went with the cheaper method .. But now I kinda want the TTix kit 65 mm head units "I think"

So do u guys think I should go ahead ?!!! The difference is huge >_<

Thanks
-Moe

 

honestly for my self i dig the ysi. my father has a twin turbo c5r 427 c5 and a 408 f1r c5 both making around 1000rwhp. I just like the blower set up better, dont get me wrong both are crazy rides i just like how the blower hits better. Also the turbo car is very quiet as was my tt cobra which had twin 64s at 26 lbs boost made 944 rwhp and was really quiet. The blower is the opposite theirs nothing in the exhaust to muffle the noise and you get the loud blower whine and the flutter of the bov. . so with that said im in the process of putting to gether my ysi build. . . . again cant go wrong either way just preferance

 

also some shops say the turbos are easier on the motor cause their driven by exhaust so no extra load on the rotating assembly to drive it and theirs also no hp robbing again cause their exhaust driven . . .either 1 i think will get you to 1000rwhp and detenation or driver error can terminate a motor real fast with either set up

 

I completely agree with but my concern is the life of the engine

 

yeah that was my concern ,, I also believe that a huge part of the engine life depends on the driver and driving habits

 

ya seriously bro w.e. your set up is if you detinate, miss a shift, go lean, run outa meth, exc. under boost your F*cked. . I mean your building the bottom end if its put together right with good parts should last either way + ysi is an easier blower to spin than pro chargers. . . Turbos are less strain cause exhaust driven and some say easier to make power at lower boost cause no hp lost due to driving them. . . I just like the louder set ups and if you go turbo just size them correctly so its not like a single turbo super . . .wait 4 it. . .wait 4 it . . . .booom full boost,shift . .repeat

 

Turbos.

/end

 

IMHO whether turbo or blower,on the same motor there should be no measurable difference in the life of the engine as long as you don't screwup by detonating or over heating.Most guys that take care of their motors never reach the point were a motor just wears out.If you are sitting around waiting for your turbos to hit then you have the wrong setup.I have twins on a 403 and it hits so fast you don't have time to think.My car will kill Nitto DRs at anything under 60MPH and I don't make near as much power as a lot of other cars in this forum.My setup must be close though as if I hit it from a dead stop on street pavement the car almost dead hooks with the same tires.I've owned a lot of fast cars but this one feels like it would be tough to beat off the lights even by a more powerfull car.I think with a comparable blower setup the car would destroy the tires off the lights and that car would loose to something less powerfull that hooked.I've been a turbo guy for over 20 years but would not think twice about running a blower if all I wanted was pure power.30HP or what ever it takes to turn a blower means nothing when you get into the 900+ range.I also like the fact that with a proper boost controller you can control the power on a turbo car.In these power ranges the guy that hooks wins on the street.Not the guy with the most power.Blowers are usually an easier install and less money.

 

true true .. I'll think under this chair until I get a higher vote for what ever force induction

 

got it

 

Well said

I put my thinking hat on

 

Thank you guys

I really appreciate your time

You said it all - "I went with the cheaper method" Have twin turbos on both my 03's with the proper set-up there is no wait (lag) the turbo is much more efficient both in producing power/torque and much easier on the engine. While a sales pitch go to the STS site and review the differences they advertise. Good luck with whatever you decide.

 

They don't quite hsve that right. A turbo causes significant back pressure, and that's how the parasitic load of driving the compressor takes a toll on the power output. Either way, the compressor isn't driven for free.

I know, there's plenty in print saying otherwise. It's a popular wives tale that's been regurgitated for at least thirty years.

 

The print and wives tale just happen to be backed up by all kinds of technical information and studies. Being kind it takes less than 5 HP to drive a turbo and a supercharger takes well over 100 HP and can easily approach 150 HP. Per dollar spent the turbo will provide more HP.

Another point is that the supercharger is always on and using that necessary HP and gas, the turbos only on when you are using it. Seems that would also make it more fuel efficient and easier on the motor.

In any case do your homework and whichever way you go will be the right way for you

 

Turbos, because you can adjust boost without changing a pulley or using a restrictor plate. You can run low boost on the street and dial it up at the track and/or dyno. Also, the turbo setup will not have any belt alignment or slipping issues (not that its a big issue but it will require additional parts to get it 100% right imo).

I went with a sc setup though because its less expensive (initially) and its slightly easier to install but if I could start over I would go with a turbo setup. Its not a significant difference in price after you add in the cost of headers, flip drive/direct drive, 8 or 10 rib setup, balancer, tensioners, etc.

Turbo...much more fun, and cooler to say

 

I dig the TTiX and the sleeper personality. Maybe give your setup a try and if you want a change, sell it later? Look at z06wanted, he's tried one of everything on his.

 

A common thing for people miss is that while it may take a calculated or measured 50 horsepower to mechanically drive a supercharger at a certain uttput, part of this is recovered when the piston encounters less resistance on the intake stroke, or is even pushed down. So 50 hp to drive the blower isn't really a 50 hp parasitic loss. Of course, the same type of recovery also happens with a turbo.

 

true he had a ttix and now went to a ysi, would like to hear his rational for switching
