OK cool, so a T-Trim upgrade would suit it better... Not looking for 600+ really due to an auto tranny but.... I'd like to have a bit of fun.

I'll be giving Vortech a call on the 2nd and see about the cost and the time it takes to do an upgrade. Anyone done an upgrade around here that knows?? Tried to search and keep getting the run-around about it.

Thanks!

 

Thinking of doing 928 and T-trim! Has anyone seen any issues with that setup?

 

The 928 is meant for the standard S or SC trim blower; the T-trim volute will be too big for the 928 impeller....it's either one or the other, and I have a feeling both would have somewhat equivalent performance to 500whp...

 

Ok, thanks. I remember a while back I read somewhere that a SC could be built toward T-trim specs. Just exploring ways to get in the mid 500's.

 

T-Trim volute is a different shape than the 928 impeller and will definitely not work together. I would go with the 928 impeller although I am biased.

 

You are correct; Vortech does have some sort of program to rebuild your stock blower to a T-trim...contact Vortech for more details...

 

I will be contacting Vortech on the 2nd to check into the re-build and see if it preforms like the actual T-Trim... If using the SC trim housing, which is smaller, it will be interesting to see if it flows the same. If not I will see about a 'trade in' to see if they can give a credit to trade in my unit for an actual T Trim....

I am up in the air right now between the T Trim or the 928 upgrade... Seems the 928 works well also and would be a tad less expensive. Both would get into the high 400's to mid 500's without a problem it seems.

 

The Cost is just not Worth it..... and you can not get upgraded bearing with the rebuild and it will not be a True T-Trim.

928 is by Far the Best way to go and for less cost, if your not getting a Whole New Blower.

 

Vortech's Trade In Program SUCKS........First you will Pay Retail for your Blower, and they will give you about $700 credit for your old one......
Superchargers Online's is about $300 cheaper, and he will do better than that if you Call for a Price....
Buy a New Blower from SC online and Sell your old one on craigslist.

 

Ah that's right, I almost forgot about SC online. Thanks for the reminder! I'll see if they are open and around tomorrow.

 

This is a Quote from SC online...

Note: Vortech's Price on a V1 T-Trim is $2901


The V-1 CCW T-Trim that Vortech offers has these little metal "ears" that interfere with the bracket and this little ears need to be grind down in order to fit. So there is no direct drop in for this, and it will require a little modification to fit completely.

This V-1 head unit goes for $2,489.00.

Vortech also offers a V-2 T-Trim which is a direct replace (350z) for $2,449.00, in which does not have anything you need to grind off to fit. The difference is the V-2 is that it is slightly more quiet since they use helix cut gears where the V-1 has straight cut gears. And the bearings are not as good as the V-1. Both head units are heavy duty.

Hmmm?? Why wouldn't the bearings in the V2 be as good as in the V1? That's interesting to learn.

 

More Info from SC Online


Vortech does offer a V-2 SC-Trim to a V-2 T-Trim Upgrade for around $599.00. However, it does not convert the head unit over to a true heavy duty T-Trim.

Within this upgrade it uses the same bearings and seals of your head unit, and they only thing the modify is the Impeller and the Volute.

What makes a head unit heavy duty are the bearings. A heavy duty head unit has higher speed bearings and the gear case has larger housings to support these high speed bearings.

So when you upgrade to a T-Trim you do not get these heavy duty bearings for they do not include a case in their upgrade. So they only upgrade to a T-Trim impeller which flows more air and a larger volute to also support this increase air flow.

 

Because of the Gear Case Design, there is more room to fit a bit larger Bearing.....

 

$599 is not bad though... But for that it almost seems that the 928 upgrade would do the same thing...

Think I would rather replace the entire unit and have a brand new one for this build. Hope my pockets can withstand it.

 

So the V2 (not a rebuild) is a smaller overall unit than the V1? But the V2 has the helix cut gears where the V1 are straight?... Is the main difference just the quietness then and no difference on cfm or rpms?

 

V1 or V2 or V3 its just talking about the Gear Case (back of blower ) all the same size.

The V1 has super loud gear noise, V2 quiet.....

It has nothing to do with CFM (front of blower)

I would not worry about Rpm to much, I run my V2 with STD Bearing to 62,000rpm..... But their is always some belt slip with a Serp.

The V7 YSI is rated at 65,000, and I know many mustang guys say 72,000 Plus is the Sweet spot..... I read about running them up as much as 80,000.

 

That YSI does sound pretty sweet but a cog set up sounds like it would have to be fabricated to get it to stick and that can cost mucho bucks... Plus I would not even be able to use the potential of it since I am definately limited by an auto tranny.

 

You can have your trans Built just like your motor..... or just put a Hi Perforance Valve Body in it.

 

And for almost the same amount money... This build will be stretching my limits at this time and with the 2013 economy not looking all that hot I will have to save up again for the tranny build... I do not put anything on my credit cards unless I have the cash to back it up and I can pay it off the very next payment cycle... Unlike this government of ours, that is how I roll fiscally.

I will be having a TranGo VB put into it and I am also looking into ACT clutchpacks as well as a tranny cooler but still, how much can that take without having to rebuild it in a short amount of time.

I am going to be happy in the 500 range and STAY happy for awhile.
