Yeah..360 pounds of torque, but at what RPM? Thats what matters... the turbos make the torque down low, where it really matters.

 

True, turbos are more functional in day to day driving in that sense. I'm pondering between single turbo or the Vortech, but am leaning towards the Vortech because if I blow my engine (which I've been reading on a regular basis recently on all forms of kits), I'd really regret going turbo. I was initially strongly thinking of ST, but in terms of long term reliability, I'd err on the safe side.

One question to ponder also is how much is really enough? Either way, both types of induction provide adequate power for most drivers. How many of us really push the car to the limits or hit the track where it can be used? The traffic in most U.S. cities are terrible; you'd spend most of your time bumper to bumper. When I start to think that I need all that power, I remind myself of this question lol.

 

My bad my TQ was 300lbs.

 

That's enough for me as well. Now they just need to get a version for the 298HP engine.

 

I thought that seemed high for a s/c. I was thinking that is one hell of a tuner.

 

I am also considering FI and I don't want to regret going Vortech...

My understanding is that the APS kits do not require tuning after installation. Is that true? I do remember reading about a thread along the lines of the "first blown APS" or some such - but as I recall it was attributed to installer error?

Anyway if I were going turbo, the vast consensus appears to be to go with the APS kit. So given that there is less chance of a tuning mishap - it would *seem* that there is more chance of blowing an engine with the Vortech.

Now I don't classify blowing the transmission in that statement. So I understand that the TT with their added low end torque put more strain on transmissions and valve body and torque converter (for autos) upgrades are a necessity.

My feeling has been that under 400 rwhp, the chance of blowing something is pretty low - for either Vortech or TT - can anyone find an instance where this has not been the case?

 

There have plenty of guys that blew their motor up well below 400whp. The most important aspect of FI is the tune. The reason for APS' success of not blowing up motors IMO (the 1 that blew was an overheating problem due to install) is that their kit comes with a pre-tuned and locked Unichip for engine management. Only authorized unichip tuners can tinker with it. These authorized unichp tuners are very experienced, thus the chances of them fuking up your motor because of the tune is highly unlikely. Also besides the fact that the APS kits come with a fuel system, they also come pre-tuned to run a little rich which adds another safety margin.

 

Gman, one question. Maybe we should ask Randy but I remember he was pushing about 330 ft/lbs of torque with his Vortech? I've been researching the Vortech option and a tuner said it was possible to get 350ft/lbs with a unichip for the tuning management.

RC, yeah I've been researching the transmission issue. The suggestions so far for longevity are a tranny cooler together with a VB. There are ATs out there pushing under 400hp for quite sometime with no mods, but for a long term reliable setup, I'd go with the cooler and VB.

 

Hey all,

I am not bashing the vortech kit at all. It definately brought a smile to my face when I smashed the gas pedal, but it wasn't enough for me. Before the ST's kits came on the market Vorteh was a good option IMO, but now I don't see the need when for about the same price you can get the same power, more tq, and upgradeability with the ST's.

I guess as more times go by and the ST's prove themselves to be safe more people will lean toward them instead of the vortech. Time will tell.

 

Gman, don't apologize, I'm not implying that you are lol. I'm just looking for your opinion thats all. The whole kit will cost me about 7k+, with larger injectors/ Unichip/fuel pump/ Vortech/tranny VB and cooler if I can squeeze it in. Don't get me wrong, I am considering the APS ST. But the downside is that the parts and support will not be stateside and that concerns me. Turbonetics kit is still new, though I read of one ST blowing on the Z forums (that appears questionable because it appears that the owner/tuner had issues).

 

[1] the reason every one changes out the belt is , that the Goodyear that comes with the kit stretches very easy
[ 2] Loose cogs ???? never
[3] breaking off the MAF sensor????? who did this ???? shouldnt happen unless your fooling around with it for some other reason
[4]dust...you mean belt dust.....only if the install was done wrong and the belt hits a the small bolts for the timing cover
[5]BOV whistles...some like it..some dont..sounds like a jet plane ....Also at idle ..the SC and idler pulley will make noise if the cog belt isnt at an exact tention...seems to be a sweet spot for it.


Would I go SC again if I had to do it all over again ? Dont know . Am I going to switch to a TT set up . Defenitly not any time soon . I broke a ringland on the #5 piston and rebuilt the lower end...added cams and return fuel system and 550 injectors....T-trim blower . With adjusted to Dynojet numbers...Im at 455whp and 345trq. making 13.5psi at 6000rpm...belt starts to slip after that . With a bigger intercooler to flow more air...I'll mkae close to 15psi.
ALL Kits , SC , ST , Or TT set ups will have problems to over come . EVEN APS Kits !!!!! The more I read about the small problems on this forum that all kits have the more I think I will just stay with what I have and work on it . I have an AT5 and if it was a MT6 I would be getting close to 500whp with this SC and that is plenty for me....DO I regret going with the Vortech ???? Hell No...would I do it again....Hell YES

 

I was gonna say...DAAMMNNN...I only got 328ft lbs peak torque at 4850RPM...
