Just wondering. I'm guessing they do, but I know they have the new SQ trim so I wondered if they had phased out the V1 S trim.
Thanks

I think you can but the dealers would consider it a special order. The SC is the old V1 S-trim. Vortech spins it slower for the 5 psig rating.

As far as I know you can still get it, as for the S-trim and SC being the same, I'll have to disagree.
I called Vortech today, and you can still order the loud V1 S trim, you just have to specifiy that's the one you want.
This is incorrect. The V-1 S is still just as available today as ever. Although, the V-2 SQ seems to be the unit of choice from most of our customers, so many of our stocking distributors would be more likely to have an SQ system in stock over an S.Quote:

The SC-Trim has replaced the old A-Trim units because of its ease of upgradeability. The SC-Trim and S-Trim units are not the same supercharger. The SC-Trim has a different impeller which at the same RPM will produce less boost pressure than an S-Trim. The SC-Trim is capable of the same maximum boost as the S-Trim, it just needs to be spun faster in order to do so.
The concept of spinning the SC-Trim slower described by aseecobra could never apply because a belt driven charger's impeller RPM is directly correlated to the engine RPM. Unless, of course, he was implying we were including a larger supercharger pulley to make the supercharger spin slower, but this is also incorrect as both systems include a 3.33" drive pulley.
Do you think vortech will ever post the compressor map on their site for the SC-trim?
I was actually just reading a little blurb in an old MM and FF that was talking about how Vortech had just introduced the SC trim. They said that it uses the S trim impellar, but the tops are cut off to limit the amount of boost it produces. Other than that, they are supposed to be very similar. I personally have no real idea though, I'm just going off what I have read.
racer x,
Are you an employee of Vortech Engineering?
According to Vortech's technical people and the dealer I recently bought my SC-trim from the V-1 series SC-Trim head unit is the same as the V-1 S-trim head unit. I was told by Vortech that only difference is the SC-trim has a 6 rib pulley. The SC has the same straight cut gears, same gear ratio, same 3.33" pulley diameter and same impeller as the V1 S-trim.
Concerning the impeller, I have removed the S-trim that is 4 years old from my other mustang and compared the impeller to this new SC-trim and they are visually the same.
Now about what I meant concerning blower RPM and spinning it slower......the SC-trim has a 6" diameter crank pulley and the S and SQ-trim has a 6.87" diameter crank pulley. You do the math.
Chris
Did you actually remove the impellers from their housings and compare the two?Quote:

According to Vortech (And 5.0 magazine) the SC trim is a S trim impeller trimmed down to limit boost.
:) GOOD! If anythign ever happened to my S-Trim, I would never want a SQ! I love my nice and loud S-Trim!!!Quote:

Yes, I am an employee of Vortech, as it says in my sig. I can be reached at Vortech by calling (805) 247-0226 x236. My name is Brian Ellis.Quote:

Our technical assistance department would not tell anyone that the S-Trim and SC-Trim are the same unit because that is not the truth. It is true, however, that most of the components of the SC are identical to the S. A few of the other guys posting had the correct information in that the SC impeller has trimmed blades. So, the SC impeller appears quite similar to the S, but is in fact not due to the machined impeller blades. They may have the same gearcase and volute, but since the difference in impeller affects the output of the unit, it is not the same supercharger head unit, and cannot be referred to thusly.
It is unfortunate that any of our distributors would be unaware of the facts on this issue, but right after the conversion from A to SC in the entry level 86-93 5.0 supercharging system, there was some confusion as to what was what. However, by now all of our distributors should now be aware of what is included in that system.
Well, when are you guys at Vortech gonna post the SC-trim compressor map on your website???
Thanks, John
i would like to see a pic of the SC impeller
so then can someone tell me if the sc-trim is in fact different than the s and the a, why then does the vortech website say that the sc-trim comes with an a-trim supercharger, opposed to saying it comes with an sc-trim supercharger.
according to everything i have read the a is no longer being made and the sc is a new redesigned supercharger with the s impeller that is cut to limit boost. am i correct???
houstonstangguy, you are correct. The A-trim is no longer being manufactured by Vortech. I think they haven't gotten around to updating the website. You may possibly be able to find an A however, on a store shelf, it that's what you want. I have the SC-trim which is the replacement for the A. The A and SC are distinguishable by looking at the intake side of the blower. Straight impeller vanes indicates an A (or other first gen Vortech) and curved over vanes indicates an SC. When I bought mine, the A and SC had the same part number. Not sure if that's how it is now. So if you are buying new, make sure you confirm what your getting.Quote:

From Vortech's website (buried I believe under the tech/download/supercharger section) are specs for all compressors. On there, you can see that the SC has the same absolute hp potential of the S trim, but must spin several thou rpm higher to get there. One interesting note is that it has a higher max efficiency than the S-trim.
Are you thinking of getting one?

thanks for the reply. i saw that you had one and actually printed a few of the threads that you posted on because i am sure you had some of the same questions that i do.
the funny thing is that here in houston there is a pretty big performace shop that i emailed and asked about this blower. my old speed shop closed. this speed shops owner emailed me and asked me if i was talking about the "SQ" trim because there was no SC. i laughed and emailed him back and copied the vortech page with the sc trim on it and emailed it to him. i explained all that i had read about it and heard about it and he replied and told me that it "looked" like it was still the a trim blower, and i couldnt really argue with him because the info came straight from vortechs website. the thing is that i wanted them to do my install but im not gonna let someone who isnt even familiar with the blower install it. especially since i knew more about it than he did. his reply was that most of their customers prefer more boost than that and that is why he didnt know about this blower. he also said that vortech isnt very good about keeping their vendors up to date with the new systems. either way i didnt feel good about letting them do it.
to answer your question, yes i think after much debate between the novi 1000 and the sc, and going back and forth for the last 6-7 weeks i have decided on the vortech. did you get it dyno tuned when you installed it??
joe
Yeah, doesn't give you the warm and fuzzies if the speed shop doesn't know what they're installing or maybe selling you. I'm sure they "know" how to install a typical blower kit, but just aren't up on the new offerings. Actually, the kit is exactly the same as the former A kit, just the head unit is different. I installed myself. Was fairly straightforward.
Well, I think everyone who is seriously looking at the base offerings from vortech and paxton (same company, actually) goes through the same emotional rollercoaster ride deciding on what to get. I know I did.
I haven't been to the dyno yet or had it tuned and am totally itching to go check the numbers, but I want to install my boost and fuel pressure gauges before I go. And I've been lazy at getting that done (its about 65% done - just need to route the wiring and hook up to the sources). I hear a tune is worth a good 25 hp as typically the engine runs pig rich during boost with the 12:1 fmu. I'm not going to get a tune now, as I have other performance goodies awaiting install. I just want to check the numbers and maybe go with a smaller ratio fmu disk while there at the dyno. Also looking at the tweecer or pms for tuning in the semi distant future. IMO, the SC-trim is a great choice.:D
so which set of gauges did you go with? i still need those too and want them when i put the blower in.
i think im gonna go with the autometer cobalt series gauges.
That is correct. As I mentioned previously, for convenience and upgradeability, the A was replaced by the SC in the entry level 5.0 system. That way, the customer does not have to send in their head unit when they want to upgrade past 10psi., which was necessary prior to the change.Quote:
