Momentum turbo kit RELEASED!
That’s interesting, I’ve had the PowerLab kit for a while now & my brother has had it since 2008 and we’ve encountered zero issues with the placement of the wastegate, no issues with the piping and boost is holding steady…
What’s more is I’ve made 360 whp on 4 psi; my brother recently made 400 whp on 7 psi… the momentum kit is claiming 400 on 8 psi too…I’m not seeing how this kit is really an improvement on the PowerLab kit (especially the claim that “you can’t even compare it”, lol)... the PowerLab kit uses the same TiAL pieces (wastegate & BOV), v-bands for the down-pipe, etc.

Compared to Powerlab, Momentum is a far superior company in terms of product development, engineering and support. We have been hands on with both kits and there is no reason to consider a Powerlab kit with this one on the market.
It is a good match for people wanting forced induction on the stock engine with no plans to build later, and is a simpler / less expensive install than twin turbo alternatives.

When Bryan@Momentum showed up at our shop and said strap it down on the dyno and see for yourself I was stunned. Beautifully linear power curve right off the included base tune and 380whp on WG pressure on the Dyno Dynamics. Quality of kit is best in class. We will be installing our first kit on the 18th and we will report back with results.
Of course, no single turbo will have the beefy midrange of a pair of smaller twins but the results are outstanding is a great setup for the money particularly those looking to stay on a stock block. It's a couple grand more installed and tuned vs. a Vortech kit.
Our R&D team did a lot of research and designed our kit to provide reliable performance and power on all motors from completely stock to fully built. On the stock motor, our kit made 410whp at 8.2 psi on a dynojet dyno with a conservative tune. We are committed to building confidence with the end user and our products. With confidence in mind, our tune allows the end user to install the kit where they please and drive it to whichever tuner/dyno of their choice.
Different dynos make different horsepower numbers for the same given car. Our director of sales took one of our test vehicles to multiple shops and dynos and got varying results from 375 whp to 425 whp. We see the importance of a dyno as measuring performance gains as a result of modifications made.

It's all about percentage gains

Check out this blog on our website talking to more detail about this topic:
It's all about percentage gains
Baseline - 258 whp (with cold air intake, test pipes, HKS exhaust, plenum spacer, and an Osiris dyno tune)
PowerLab GT35R - 360 whp (4 psi, HKS exhaust, plenum spacer, ProEFI computer)
Gained 102 whp on 4 psi (39.5% gain)
Edit: Even more if you factor in the amount of whp I gained over stock, my baseline already included a dyno tune reflash, test pipes, and intake, and that added about 30 whp over my first naturally aspirated baseline…
Same wheels/tire setup, same dyno, etc. …obviously different days, conditions were similar (HOT…July in AZ).
Not bashing I’m just saying that comment “it’s superior, or not comparable, etc.” isn’t really true, lol…

Not bashing Momentum either... but I think it's a bit ridiculous and premature for vendors (especially ones with zero to minimal experience with the PowerLab kit in a shop, street, or track setting) to be making statements like "can't even compare this" or "best in class". And reviews from new Momentum dealers should be taken with a grain of salt for obvious reasons ($$$). Real world results and impartial reviews from end users are what really matter. But that takes time.So it's way too soon IMO for superiority claims to be given any merit. Although there are striking similarities with how Momentum copied PowerLab's basic design and most components... don't forget the Boosted Performance single turbo kit either. If comparisons are going to be made between single turbo kits, the BP kit should be included in the discussion also. It has received positive reviews for quality and ease of install as well, and several have praised Sasha for his customer service. But that kit also lacks enough end users and real world results at this point to substantiate any claims of performance superiority.
It's nice to see more single turbo kit options for the VQ community. The added competition from Momentum will motivate others, including PowerLab and Boosted Performance, to improve their products ...which benefits the whole community.

i couldn't find the most recent one, this is before meth and the sp cutout at 20psi IAT was around 130

Quite a few in depth pics, videos and graph of Momentum on a G coupe.

the only 2 GT37s that fit (without custom T3 turbine housing) are the 3776 and the 3782, neither or which according to Garrett are dBB.
The 3776 has a 55mm compressor and the 3782 has a 60mm compressor. Both smaller than the GT3582r. But it does use a 72.5mm turbine compared to the 68mm on the gt35r.
so in the end, and as we have seen, there's not much to gain by going to a gt37.
Just seems a little silly that in a wideopen market to manufacture a me-too product. There still must be a big marketshare available in the stock block/ limited hp single turbo arena.
The kit looks very good
, as one would expect with a known standard thats been on the market for years

(jk bud) Not exactly many ways to run things. They all have very similar placement for a reason. I've been in this business for a LOOOOONG time. I have NEVER seen a manufacturer be as in depth, as close with it's vendors and close to the end consumer like Momentum has. They came to the shop, they shook our hands, they showed us their product and we loved it. We're looking forward to doing a lot of business with them and building some great cars with their products.

thats not possible with Greddy, GTM, PL, SFR, JWT, BP, APS?
The hp levels were very conservative and you'd expect any turbo kit worth its salt to be able to run 400whp all day everyday. Thats more a testament to a proper motor/tune. If they dumped in race gas and bumped it up to 550whp, that woulda been a great test to see how the AITs change, since that is the #1 issue concerning that style kit. That would have been a good evaluation.
any of those incorporate a 67+mm turbo? Which combo would be better than the gt35r/GT37? Cuz, sounds like PL or Momentum should offer it as standard kit.
