My friend had his Level 10 transmission fail at just over 500whp and less than a month of driving.. They also recommended no transmission cooler as their trans is "bulletproof" and here he is without a driving car.

Fast intentions does build transmissions and their reputation proceeds them.

I've learned that cutting corners will cost you way more in the long run. Just do it right the first time with the right shop and you will be better off in the long run

I just gave FI a call and asked about their 7 AT rebuilds...he said they only do that WITH their Twin Turbo package. If not, then they won't do it. They contract out to a local shop to do it for them but ONLY WITH their TT package.

So he recommended me to level 10 straight away lol, I was like uhhh...sir I heard people saying horror stories come from there but he said nah they for one, order the Flex Billet Plates from FI at times, and two, they are the best around as far as he knows when it comes to Automatic Transmission rebuilds.

I told him oh okay well they also send out the parts to the customer if they wanted to and they can either put it in themselves or have a professional aftermarket shop install it.

He said he was very surprised that they even do that because even FI said they will not touch in putting in transmissions for cars because he said too many things could go wrong.

Your tuner probably didn't have a masters' in Computer Science and prooobably wasn't titled a Master Tuner from ECUtek, haha or was he? O_O
My tuner is giving me 200% support and is willing to drive to my area (about an hour away for him) to tune the car, fine tune it, and make it close to perfect after we get the vehicle running.

He wants me to data log it weekly for him so we can fine-tune it over time.
Also he has a Masters' in Computer Science & just recently became a Master Tuner by ECUtek.

He takes a ton of pride in his customers and even though he is new to the tuning world, I have ton of faith that he will do really well with how he treats his customers (me being one of them), xD

I can always ask Seb for a 2nd opinion if anything as well since I know he is pretty much 6 hours away from me (driving). I'm in good hands both ways

*2nd Update Today* -- Informational!!!

So I gave Vortech a call asking if they upgrade the SCi blowers the same way 928 does.
They said the cost to upgrade the SCi to an SC is $306. You pay at the end, a lady will call you and ask for your payment information and you pay over the phone that way.
The upgrade that they service to is to replace the impeller with a better one that makes it a v3 SC blower.

I asked if they would take 928 parts and upgrade the blower that way with 928 parts but they said no -- that they only will do it with their parts only. I asked why, and he said because if the blower fails they don't want that to happen, I said well that would be the customer's fault and the customer's discretion as to them asking you guys to put it in or not.

Makes you kind of wonder are they only doing things for customers only or do they care about helping others at the same time? I mean, if I was a business, I would install it for them if they wish, as long as they sign something saying anything that goes wrong is not their fault afterward lol.

As for 928Motorsports, I read a full thread that had Car (The owner of 928) defend his company against someone who was crap talking them because he believed that they messed up his blower. So someone told Carl about the thread and how he was maliciously attacking 928, and Carl joined in and defended him and his company very well.
He asked if the guy could send in his blower to have 928 look at it to see the actual causes but all the guy would show is an ebay listing of pictures and how bad the blower parts looked lol.

Long story short -- he would refuse to send it to them for whatever reason which makes you wonder he probably has something to hide and is not willing to give into whatever that may be.

I want to send in my blower to 928 over Vortech because I trust Carl based on what I have researched and read. I believe they firmly stand behind their work and also some of the highest WHP supercharged Z's on this forum have had their blowers done by 928.

So in saying that, the cost of 928 is:
$1229 Base Pay + $36 Shipping + $30 additional optional rush order fee = $1295 USD.
The turn around time is about 2 weeks from the day the customer ships it and to the day it gets back to the customer.

I will give them a shot and send in my blower sometime next week (Probably Wed or Thursday) and hopefully get it back before May hits so it could be coming in at roughly the same time my engine does.

I will definitely keep you all updated on my journey and continuously upgrade the timeline as well.

================================================== ================
*Update 3 for Today*
I updated the OP regarding my tuner. It has all of his contact information on there and a bit of background information on him.
He isn't well known but I believe he is a very strong tuner and he has some unique qualities about him that made me give him a shot.
Originally I was set in stone going to Seb for my tune but I decided to give Eugene a shot and see how things go from there.
Seb has an excellent reputation already, and I know that I am in good hands with him if I went to him, however I decided to try someone who isn't very well known but whose customer service & support caught my attention (on top of the fact that he is 1 hour away from me and willing to visit me...to tune it which is unique IMO).

He does know a lot about 370z and Infiniti, and all about auto mechanical engineering and the ins and outs of why this and why that. Sometimes the information he provides to me is over the top of my head but I still try my best to understand, as one of his unique qualities is to educate his customers as best as possible about the tuning which I think a lot of tuners in the US don't do.

turtle64b · 04-03-2018, 06:24 PM

Hey, before you send it off to them, maybe look at trading it in to Vortech for the V-7! It can spin faster and push more flow than stock. Sure it can't spin as fast as theoretically possible with the 928 build, but you get more flow with the safety net of Vortech's warranty on their work. Just a thought!

Also, get an oil cooler!!!! haha

I picked up a 34-row relatively cheap and oil temps are great!

cupcakez · 04-03-2018, 06:57 PM

Where did you and how much was your 34 row cooler

If I get a v7 I cant use topz a2a kit. Means either I sell it to someone or, not lol.
Also, It isnt within my budget yet to get a v7

As much as I want to, unless the trade in value is not a lot and within like 1500 usd + the blower itself, i wont get a v7. or i can sell the a2a kit get 1500 back and trade in blower still be willing to spend 1500 that was gna go toward 928, that is also a possibility.

Does vortech do trade ins...? I only have about 6k miles on the SC lmao

I think they dont take v3 SCi superchargers that I can find...it only takes v1s it looks like and v2s?

Maybe Im tripping lol, I may call them and ask.

Also, you said the 928 upgrade is theoretically better than a v7 ysi? no way haha I would think the v7 ysi is better than the v3 sci 928 premium upgrade no? or am i tripping again lol

I got my oil cooler from a guy who bought it and then sold his car or something before he could put it on for $500 shipped.

I don't know about trading the V3 in, but it may be worth the phone call.

I said that the V3 with the 928 upgrade could spin faster than the V7 but the flow rate from the V7 was more.

milkcow500 · 04-04-2018, 04:03 PM

Vortech will give you $500-$1000 credit for a trade in, which is a joke. I literally asked them for an impeller and O-Rings and they told me that my unit needs "major repair" and is not worth keeping.

Frozenboost sells oil coolers for dirt cheap btw if you want to piece one together yourself.

So pretty much its like the situation with the v3/v7 head units vs the C38R coming out?

efficiency vs flow rate...hmm...

makes me think should i also invest in the c38r or not haha

So it sounds like you plan to buy a V7, c38r and the RJ mfg whipple...lol..

LOL
You right huh.... I didn't notice that til you said that xD
Noooo I'm not that crazy!
I just can't decide which one to get after maxing out the V3 SCi ... x_X

milkcow500 · 04-04-2018, 10:18 AM

So I'm actually swapping out my v3 for a V7 in the next week or two. Here's some things I learned from all my research.

Be very careful when listening to info provided by these supercharger companies. It's a very small market and it seems like they all like to keep things to themselves. I've had Vortech, 928, and Superchargerrebuilds all trash talk each other, which didn't give me much confidence in the industry in general.

Vortech is only interested in selling new units or doing trade ins, which is not worth it imo. I've seen harsh mixed reviews on both 928 and SCR, so I can see how it's difficult for people to decide where to send their business. To be frank, rebuilding a supercharger is not difficult. There's even full PDF guides in how to rebuild a V3/V7 you can get off other forums.

You can use the V7 with Topgunz's kit. You will need to use a different filter though, since there's less clearance and it has a larger volute (4" vs 3.5"). Here's the deal with the V3 vs V7. You want to pick which blower will suite your power needs (For efficiency sake). If you are finalizing on somewhere around Evan's power range, then a built V3 will be much better suited. You'll also have better power under the curve. Reliability issues start becoming a coin flip once you start overspinning the blower though, so keep this in mind. This is mainly because of the closed loop setup and the oil slinger being fragile. The V7 does not utilize an oil slinger.

Buy used and private sell your V3 if you are looking go this route. I bought a slightly damaged V7 for a fraction of the cost of the blower NIB. Play the waiting game and pick up a good deal. Lurk around on ebay and the mustang/corvette forums.

Best of luck.

Thanks so much for your feedback!
I just found a shop right now saying they are willing to take on the job to rebuild the v3 sci for me as long as I can provide them with the parts and the isolated head unit.

I told him its from 928motorsports and I am looking for a shop to replace the bearings and impeller with upgraded ones.

He says he never done a supercharger rebuild before because his shop does turbo rebuilds, not superchargers.
He said if I can provide him with the PDF file for help and the parts from 928 as well as the head unit itself, he is willing to take on the job.

He does not know the price to charge as he needs to look it up in the service manual for prices lol.

Now I have 2 choices:
1) Purchase 928 upgrade package and have them ship it to me, and I give it to this shop to rebuild.

2) Send in the headunit straight to 928 have them rebuild it and send it back.

What to do....
I would assume he is more than capable of doing it because he is experienced in rebuilding turbochargers.
.and said superchargers are much more simpler.

What do you guys think? Ideas?

milkcow500 · 04-04-2018, 01:29 PM

If he has a good rep and knows how to rebuild a turbo, then he should have no issues.

I know there's a pdf floating around for the V3, but I don't remember where it is. You can have him refer to this one in the meantime: http://www.starrland.com/supercharge...%202-22-08.pdf

cupcakez · 04-16-2018, 04:04 PM

IPP Stage IV Update:

I messaged Kyle and he said they just got the custom pistons in last week! (11.0:1 CR)

He will go to the machine shop tomorrow and see what's up -- try to get a firm ETA on it for me and then let me know, and then I will let /you/ guys know!

Super excited. Getting closer!

Also, I have a mobile mechanic that is going to rebuild the supercharger for me this coming Friday using the 928 parts (Impeller & Seals / Bearings) that I ordered from 928motorsports.

I did not know there is instructions for installing and rebuilding it.

https://928motorsports.com/installpd...on_Vortech.pdf

https://928motorsports.com/installpd...ealinstall.pdf

- It has torque specs and everything which is super helpful.
